Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method and a communication device. Background Art

[0002] In the process of the evolution of the fifth generation mobile communication system (5G) to 5G-advanced (5G-A) technology, communication and perception integration technology is considered to be one of the key technologies that can expand the service capabilities of mobile communication networks. The core idea of ​​this technology is to add perception capabilities to the mobile communication network and build the ability to detect, track and image the target, so that the communication and perception capabilities can be integrated into one network to achieve harmonious coexistence and even mutual benefit.

[0003] In the communication and perception integration scenario, the network device can send perception signals and communication signals to the terminal device at the same time. The perception signal is used to obtain information such as the location, speed, and type of the terminal device, and the communication signal is used to transmit data information or control information. The terminal device obtains the perception signal and the communication signal; analyzes the communication signal, and obtains the data information or control information transmitted by the communication signal.

[0004] However, the following technical problems exist in the communication-awareness integration technology: the communication efficiency of the communication signal is low. Summary of the invention

[0005] The present application provides a communication method and a communication device, which are beneficial to improving the communication efficiency of communication signals.

[0006] In the first aspect, a communication method is provided, which can be executed by a terminal device, or by a module (such as a processor, a chip, or a chip system, etc.) applied to the terminal device, or by a logical node, a logical module, or software that can realize all or part of the functions of the terminal device. The method includes: receiving first indication information, the first indication information is used to indicate that a first signal in a first time period is associated with a second signal, or is not associated with the second signal, wherein the first signal is used for communication, and the second signal is used for communication, perception, or energy transmission; receiving the first signal and the second signal under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, or receiving the first signal under the condition that the first indication information is used to indicate that the first signal is not associated with the second signal; demodulating the first signal based on the first indication information.

[0007] The first signal is used for communication, that is, the first signal may include control information or data information, and the first signal may also be referred to as a communication signal, which is not limited in this application. The second signal is used for communication, one or more of perception or energy transmission. If the second signal is used for perception, that is, the second signal is used to obtain information such as the location, speed, and type of the terminal device, the second signal may also be referred to as a perception signal, which is not limited in this application.

[0008] In one possible implementation, the first indication information is used to indicate that the first signal in the first time period is associated with the second signal, that is, the first signal in the first time period is associated with the second signal. If the first signal is associated with the second signal, it means that the terminal device is in a communication perception integration scenario. Among them, the first signal in the first time period is used to indicate that the first signal is sent or received in the first time period. The first time period is used to represent a period of time, and the embodiment of the present application does not specifically limit the length of the first time period.

[0009] Under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first signal and the second signal can be received, and interference of the second signal can be removed when demodulating the first signal.

[0010] In this implementation, based on the first indication information, it can be determined that the second signal will interfere with the demodulation of the first signal. When demodulating the first signal, the interference of the second signal can be removed, which is beneficial to improving the communication efficiency of the first signal.

[0011] In another possible implementation, the first indication information is used to indicate that the first signal in the first time period is not associated with the second signal, that is, the first signal in the first time period does not have an associated second signal. If the first signal is not associated with the second signal, it means that the second signal will not interfere with the first signal. In other words, the network device does not send the second signal for perception, and the second signal will not interfere with the first signal.

[0012] Under the condition that the first indication information is used to indicate that the first signal is not associated with the second signal, the first signal can be received, and the second signal does not need to be considered when demodulating the first signal.

[0013] In this implementation mode, the terminal device can determine that the second signal will not interfere with the demodulation of the first signal based on the first indication information, and can ignore the interference of the second signal when demodulating the first signal, which is beneficial to improving the demodulation efficiency of the first signal.

[0014] In combination with the first aspect, in certain implementations of the first aspect, under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first indication information is also used to indicate the type of the second signal, wherein the type of the second signal includes one of a communication signal, a perception signal, a synaesthesia signal, or an energy transmission signal.

[0015] The type of the second signal may be a perception signal, a communication signal, a synaesthesia signal (i.e., a signal used for both communication and perception), or a signal with other functions other than communication and perception, such as an energy transmission signal (i.e., a signal used to transmit energy). When the type of the second signal is a communication signal, the second signal may be a data signal, a control signal, or a reference signal.

[0016] It should be noted that when the first indication information indicates the type of the second signal, it is not limited to directly indicating the function of the second signal, such as perception, communication or energy transmission, but can also implicitly indicate the type index of the second signal, such as the first type, the second type or the third type, wherein the first type can be used to indicate that the type of the second signal is a perception signal, the second type can be used to indicate that the type of the second signal is a communication signal, and the third type can be used to indicate that the type of the second signal is an energy transmission signal.

[0017] Under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first indication information is also used to indicate the type of the second signal. The terminal device can determine the type characteristics of the second signal based on the first indication information, thereby selecting an appropriate receiving method to eliminate the interference of the second signal on the first signal and improve the receiving performance of the first signal.

[0018] In combination with the first aspect, in certain implementations of the first aspect, under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first indication information is also used to indicate a relative power value between the first signal and the second signal.

[0019] The relative power value of the first signal and the second signal is used to represent the power difference between the first power and the second power in the direction in which the terminal device receives the second signal. The relative power value may be positive, negative, or zero, and this application does not limit this. The unit of the relative power value may be decibel (dB), but this application is not limited to this.

[0020] The first indication information is used to indicate a relative power value between the first signal and the second signal, and includes multiple possible implementation methods.

[0021] In a possible implementation, the first indication information may include a value, which is a relative power value of the first signal and the second signal. This implementation is simple and direct, and the terminal device can directly obtain the relative power value of the first signal and the second signal from the first indication information.

[0022] In another possible implementation, the first indication information may include multiple relative power values, one of which is the relative power value of the first signal and the second signal. In this case, the terminal device may also receive another indication information from the network device, which is used to indicate the index value of the relative power value of the first signal and the second signal in the above multiple relative power values. Alternatively, the terminal device receives another indication information from the network device, which is used to indicate multiple relative power values ​​of the first signal and the second signal, and the terminal device also receives the first indication information from the network device, which is used to indicate the index value of the relative power value of the first signal and the second signal in the above multiple relative power values. Among them, the multiple relative power values ​​can be called candidate values ​​of the relative power values, which is not limited in this application.

[0023] This implementation indirectly indicates the relative power value of the first signal and the second signal through two indication information, which improves the security of information transmission compared with direct indication.

[0024] In combination with the first aspect, in certain implementations of the first aspect, under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the method also includes: receiving second indication information, the second indication information being used to indicate at least one of a sequence of the second signal, a frequency domain coefficient of the second signal, or a time domain position of the second signal; and demodulating the first signal based on the first indication information, including: demodulating the first signal based on the first indication information and the second indication information.

[0025] Under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the terminal device needs to consider removing the interference of the second signal when demodulating the first signal. The terminal device can receive second indication information from the network device, and the second indication information is used to indicate the characteristic parameters of the second signal, for example, at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal, so that the terminal device can remove the interference of the second signal when demodulating the first signal based on this information.

[0026] The second indication information is used to indicate at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal. In one example, the second indication information can be used to indicate the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal; in another example, the second indication information can be used to indicate two of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal; in yet another example, the second indication information can be used to indicate the sequence of the second signal, the frequency domain coefficient of the second signal, and the time domain position of the second signal. It can be understood that the more characteristic parameters of the second signal indicated by the second indication information, the more conducive it is for the terminal device to remove the interference of the second signal when demodulating the first signal.

[0027] In this implementation, the terminal device obtains at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal through the second indication information, which is beneficial for the terminal device to better remove the interference caused by the second signal when demodulating the first signal.

[0065] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0066] In the process of 5G evolving into 5G-A technology, communication and perception integration technology is considered to be one of the key technologies that can expand the service capabilities of mobile communication networks. The core idea of ​​this technology is to add perception capabilities to mobile communication networks and build the ability to detect, track and image targets, so that communication and perception capabilities can be integrated into one network to achieve harmonious coexistence and even mutual benefit.

[0067] For wireless communication air interface technology, in a wireless communication system, communications can be divided into different types according to the types of sending nodes and receiving nodes. Usually, 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 the long-term evolution (LTE) / long-term evolution advanced (LTE-A) communication system and the new air interface (NR) system, according to the different duplex modes, it can be mainly divided into frequency division duplex (FDD) mode and time division duplex (TDD) mode. For a wireless communication system 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 the orthogonal frequency division multiplexing access (OFDMA) method. The main feature of OFDMA is that the transmission resources are divided into mutually orthogonal time-frequency resource elements (REs). The signals sent by the transmitter are carried on REs and transmitted to the receiver. Since different REs are orthogonal to each other, the receiver can receive the signals sent on each RE separately.

[0068] The technical principle of perception is somewhat different from that of communication. In communication, the transmitter modulates information on radio waves and sends it to the receiver, which then demodulates the signal carried on the radio waves to obtain the information. However, perception requires the transmitter to send radio waves in a specific direction. When the radio waves hit the surface of the target, reflected radio waves are formed. The receiver then receives and processes the reflected radio waves to obtain information such as the target's location, speed, and type.

[0069] Perception can usually be divided into two types based on the mode: single-station perception and dual-station perception. In single-station perception, the transmitter and receiver of the perception signal are the same device. From the perspective of the perception signal process, the perception site must both send the perception signal and receive the signal reflected by the target surface. Therefore, the single-station perception mode is also called the self-transmitting and self-receiving mode. For dual-station perception, the transmitter and receiver of the perception signal are two different devices. From the perspective of the perception signal process, after the perception site A sends the perception signal, the signal reflected by the target surface is received by the perception site B. Therefore, the dual-station perception mode is also called the A-transmitting and B-receiving mode.

[0070] Currently, in the communication perception integration scenario, the following six sub-scenarios can be included from the perspective of perception mode. Figure 1Schematic diagrams of different sensing modes are shown. Figure 1 As shown, the sensed target is a vehicle, but the sensed target in the embodiment of the present application is not limited to vehicles, but can also be a low-altitude drone, a pedestrian, or other moving or stationary objects. At the same time, the sensed target can also be a terminal device with communication function.

[0071] like Figure 1 As shown in a in Figure 1, the network device must send the sensing signal and also receive the signal reflected by the sensing signal on the target surface, which is a self-transmitting and self-receiving signal of the network device. Figure 1 As shown in b in the figure, the terminal device not only sends the sensing signal, but also receives the signal reflected by the sensing signal on the target surface, which is the terminal device sending and receiving automatically. Figure 1 As shown in c, after network device 1 sends a sensing signal, the signal reflected by the target surface is received by network device 2, which is a signal sent by network device 1 and received by network device 2. Figure 1 As shown in d in FIG, after terminal device 1 sends a sensing signal, the signal reflected by the target surface is received by terminal device 2, which is the signal sent by terminal device 1 and received by terminal device 2. Figure 1 As shown in e in Figure 1, after the network device sends the sensing signal, the signal reflected by the target surface is received by the terminal device, which is the network device sending and the terminal device receiving. Figure 1 As shown in f, after the terminal device sends the perception signal, the signal reflected on the target surface is received by the network device, which is the signal sent by the terminal device and received by the network device.

[0072] The embodiments of the present application focus on the study of three sub-scenarios: network devices sending and receiving by themselves, network device 1 sending and network device 2 receiving, and network device sending and terminal device receiving. In these three sub-scenarios, while the network device is sensing, it is also communicating with the terminal device.

[0073] For example, Figure 2 A schematic diagram of a communication scenario integrating communication perception is shown. Figure 2 As shown in a in Figure 1, the network device must send the sensing signal, receive the signal reflected by the sensing signal on the target surface, and communicate with the terminal device. Figure 2 As shown in b in FIG, after network device 1 sends a sensing signal, the signal reflected by the target surface is received by network device 2, and network device 1 also communicates with the terminal device. Figure 2 As shown in c, after the network device sends the perception signal, the signal reflected on the target surface is received by the terminal device 1, and the network device also communicates with the terminal device 1.

[0074] The terminal device involved in the embodiment of the present application is used to send an uplink signal to a network device, or to receive a downlink signal from a network device. The terminal device may be a mobile phone, a tablet computer, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control, or other devices; it may also be a mobile object such as a vehicle or a drone with a communication function. The network device involved in the embodiment of the present application is used to receive an uplink signal from a terminal device, or to send a downlink signal to a terminal device. The network device may be a network device of LTE or NR, and may be a base station (NodeB), an evolved base station (eNodeB), a base station in a 5G mobile communication system, a next generation mobile communication base station (next generation Node B, gNB), a base station in a future mobile communication system, or an access node in a Wi-Fi system, etc.

[0075] In the above Figure 2 In the communication and perception integration scenario shown, the network device can send perception signals and communication signals to the terminal device at the same time. The perception signals are used to obtain information such as the location, speed, and type of the terminal device, and the communication signals are used to transmit data information or control information. The terminal device obtains the perception signals and communication signals; analyzes the communication signals, and obtains the data information or control information transmitted by the communication signals.

[0076] However, the following technical problems exist in the communication-awareness integration technology: the communication efficiency of the communication signal is low.

[0077] In view of this, an embodiment of the present application provides a communication method and a communication device, wherein a network device informs a terminal device through a first indication information that a first signal has an associated second signal. Based on the first indication information, the terminal device can determine that the second signal will interfere with the demodulation of the first signal. When demodulating the first signal, the interference of the second signal can be removed, which is beneficial to improving the communication efficiency of the first signal.

[0078] In order to facilitate understanding of the method provided in the embodiments of the present application, the following points are first explained:

[0079] First, in the embodiments of the present application, "used for indication" may include being used for direct indication and being used for indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated may be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated may also be indirectly indicated by indicating other information, wherein the other information has an association relationship with the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to implement the indication of the information to be indicated by means of a pre-agreement (such as a protocol provision) on whether a certain information element exists, thereby reducing the indication overhead to a certain extent.

[0080] Second, in the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0081] Third, in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that under certain objective circumstances, the device (such as the terminal device or access network device described below) will make corresponding processing, which is not a time limit, and does not require the device (such as the terminal device or access network device described below) to have a judgment action when implementing it, nor does it mean that there are other limitations.

[0082] Fourth, in the embodiment of the present application, "pre-defined" may be a protocol definition. Among them, "pre-defined" may be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit the specific implementation method.

[0083] Fifth, the “protocol” involved in the embodiments of the present application may refer to a standard protocol in the field of communications, for example, it may include a long term evolution (LTE) protocol, an NR protocol, and related protocols used in future communication systems, which is not limited in the present application.

[0084] In order to better understand the embodiments of the present application, the communication method provided in the embodiments of the present application will be described in detail below.

[0085] Figure 3 A schematic flow chart of a communication method 300 provided in an embodiment of the present application is shown. The method 300 can be applied to the above Figure 2 The communication perception integration scenario shown in Figure 1 is as follows. Figure 3 As shown, the method 300 may include the following steps:

[0086] S301. The network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information, where the first indication information is used to indicate that a first signal within a first time period is associated with a second signal, wherein the first signal is used for communication, and the second signal is used for one or more of communication, perception or energy transmission.

[0087] The first signal is used for communication, that is, the first signal may include control information or data information, and the first signal may also be referred to as a communication signal, which is not limited in the embodiments of the present application. The second signal is used for communication, one or more of perception or energy transmission. If the second signal is used for perception, that is, the second signal is used to obtain information such as the location, speed, and type of the terminal device, the second signal may also be referred to as a perception signal, which is not limited in the embodiments of the present application.

[0088] The first indication information is used to indicate that the first signal in the first time period is associated with the second signal, that is, the first signal in the first time period is associated with the second signal. If the first signal is associated with the second signal, it means that the terminal device is in a communication perception integration scenario. Among them, the first signal in the first time period is used to indicate that the first signal is sent or received in the first time period. The first time period is used to represent a period of time. For example, the first time period can be 1 time slot, 1 micro time slot, or a time period composed of multiple symbols. The embodiment of the present application does not specifically limit the length of the first time period.

[0089] S302. The network device sends a first signal and a second signal to the terminal device, and correspondingly, the terminal device receives the first signal and the second signal.

[0090] The network device may send the first signal and the second signal to the terminal device, and the sending time of the first signal and the second signal may both be within the first time period, but the embodiment of the present application does not limit this. The channels through which the network device sends the first signal and the second signal may be the same or different, and the embodiment of the present application does not limit this.

[0091] S303. The terminal device demodulates the first signal based on the first indication information.

[0092] The terminal device receives the first indication information and can determine that the first signal is associated with the second signal. The first signal is associated with the second signal, and when the first signal is demodulated, the second signal will interfere with the demodulation. After the terminal device receives the first signal and the second signal, it can remove the interference of the second signal as much as possible when demodulating the first signal based on the first indication information.

[0093] In the scenario where the network device sends and receives the signal by itself, the network device can receive the echo signal of the second signal and sense it based on the echo signal. The echo signal is used to represent the signal reflected by the second signal on the surface of the terminal device. In the scenario where the network device sends and other devices receive the signal, another network device or another terminal device can receive the echo signal of the second signal and sense it based on the echo signal.

[0094] In the communication method provided in the embodiment of the present application, a network device informs a terminal device through a first indication information that a first signal has an associated second signal. Based on the first indication information, the terminal device can determine that the second signal will interfere with the demodulation of the first signal, and can remove the interference of the second signal when demodulating the first signal, which is beneficial to improving the communication efficiency of the first signal.

[0095] In the communication perception integration scenario, the first indication information can be used to indicate that the first signal in the first time period is associated with the second signal. In the communication scenario, the first indication information can be used to indicate that the first signal in the first time period is not associated with the second signal.

[0096] For example, Figure 4 FIG. 4 is a schematic flow chart of another communication method 400 provided in an embodiment of the present application. Figure 4 As shown, the method 400 may include the following steps:

[0097] S401. The network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information, where the first indication information is used to indicate that a first signal within a first time period is not associated with a second signal, wherein the first signal is used for communication, and the second signal is used for communication, perception or energy transmission or one or more thereof.

[0098] The first indication information is used to indicate that the first signal in the first time period is not associated with the second signal, that is, the first signal in the first time period does not have an associated second signal. If the first signal is not associated with the second signal, it means that the second signal will not interfere with the first signal. In other words, the network device does not send the second signal for perception, and the second signal will not interfere with the first signal.

[0099] S402. The network device sends a first signal to the terminal device, and correspondingly, the terminal device receives the first signal.

[0100] The network device may send a first signal to the terminal device within a first time period.

[0101] Exemplarily, the network device may send a first signal to the terminal device within a first time period via a physical downlink shared channel (PDSCH).

[0102] S403. The terminal device demodulates the first signal based on the first indication information.

[0103] When the terminal device receives the first indication information, it can determine that there is no associated second signal with the first signal, and when demodulating the first signal, it can ignore the interference caused by the second signal to the demodulation.

[0104] In the communication method provided in the embodiment of the present application, the network device informs the terminal device through the first indication information that there is no associated second signal with the first signal. Based on the first indication information, the terminal device can determine that the second signal will not interfere with the demodulation of the first signal. When demodulating the first signal, the interference of the second signal can be ignored, which is beneficial to improving the demodulation efficiency of the first signal.

[0105] The first indication information can be used to indicate that the first signal in the first time period is associated with the second signal, and can also be used to indicate that the first signal in the first time period is not associated with the second signal. The terminal device can determine the demodulation method for the first signal based on the first indication information, which increases flexibility.

[0106] Exemplarily, the first indication information may include a field, which is used to indicate whether the first signal in the first time period is associated with the second signal. For example, the field may be a bit, and when the bit is 0, it indicates that the first signal in the first time period is not associated with the second signal; when the bit is 1, it indicates that the first signal in the first time period is associated with the second signal. Alternatively, when the bit is 1, it indicates that the first signal in the first time period is not associated with the second signal; when the bit is 0, it indicates that the first signal in the first time period is associated with the second signal.

[0107] Table 1 shows an example of one-bit indication information.

[0108] Table 1

[0109] Bit value meaning 0 The first signal is not related to the second signal 1 The first signal is associated with the second signal

[0110] As shown in Table 1, when the bit is 0, it indicates that the first signal in the first time period is not associated with the second signal; when the bit is 1, it indicates that the first signal in the first time period is associated with the second signal.

[0111] As an optional embodiment, under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first indication information is also used to indicate the type of the second signal.

[0112] The type of the second signal may be a perception signal, a communication signal, a synaesthesia signal (i.e., a signal used for both communication and perception), or a signal with other functions other than communication and perception, such as an energy transmission signal (i.e., a signal used to transmit energy). When the type of the second signal is a communication signal, the second signal may be a data signal, a control signal, or a reference signal.

[0113] Exemplarily, the first indication information may include a field for indicating whether the first signal in the first time period is associated with the second signal, and whether the second signal is a communication signal or a perception signal. For example, the field may be two bits, and the two bits are used to indicate whether the first signal in the first time period is associated with the second signal, and whether the second signal is a communication signal or a perception signal. Table 2 shows an example of two-bit indication information.

[0114] Table 2

[0115]

[0116] As shown in Table 2, when the values ​​of the two bits are 00, it indicates that the first signal is not associated with the second signal; when the values ​​of the two bits are 01, it indicates that the first signal is associated with the second signal, and the second signal is a perception signal; when the values ​​of the two bits are 10, the first signal is associated with the second signal, and the second signal is a communication signal; when the values ​​of the two bits are 11, it indicates a reserved state.

[0117] Exemplarily, the first indication information may include a field for indicating whether the first signal in the first time period is associated with the second signal, and whether the second signal is one of a communication signal, a perception signal, or a synaesthesia signal. For example, the field may be two bits, and the two bits are used to indicate whether the first signal in the first time period is associated with the second signal, and whether the second signal is one of a communication signal, a perception signal, or a synaesthesia signal. Table 3 shows an example of these two bits of indication information.

[0118] Table 3

[0119]

[0120] As shown in Table 3, when the values ​​of the two bits are 00, it indicates that the first signal is not associated with the second signal; when the values ​​of the two bits are 01, it indicates that the first signal is associated with the second signal, and the second signal is a perception signal; when the values ​​of the two bits are 10, the first signal is associated with the second signal, and the second signal is a communication signal; when the values ​​of the two bits are 11, it indicates that the first signal is associated with the second signal, and the second signal is a synaesthesia signal.

[0121] Exemplarily, the first indication information may include a field for indicating whether the first signal in the first time period is associated with the second signal, and whether the second signal is one of a communication signal, a perception signal, or an energy transfer signal. For example, the field may be two bits, and the two bits are used to indicate whether the first signal in the first time period is associated with the second signal, and whether the second signal is one of a communication signal, a perception signal, or an energy transfer signal. Table 4 shows an example of these two bits of indication information.

[0122] Table 4

[0123]

[0124] As shown in Table 4, when the values ​​of the two bits are 00, it indicates that the first signal is not associated with the second signal; when the values ​​of the two bits are 01, it indicates that the first signal is associated with the second signal, and the second signal is a perception signal; when the values ​​of the two bits are 10, the first signal is associated with the second signal, and the second signal is a communication signal; when the values ​​of the two bits are 11, it indicates that the first signal is associated with the second signal, and the second signal is an energy transmission signal.

[0125] It should be noted that when the first indication information indicates the type of the second signal, it is not limited to directly indicating the function of the second signal, such as perception, communication or energy transmission, but can also implicitly indicate the type index of the second signal, such as the first type, the second type or the third type, wherein the first type can be used to indicate that the type of the second signal is a perception signal, the second type can be used to indicate that the type of the second signal is a communication signal, and the third type can be used to indicate that the type of the second signal is an energy transmission signal.

[0126] Under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the network device indicates the type of the second signal to the terminal device through the first indication information, so that the terminal device can determine the type characteristics of the second signal based on the first indication information, and thus select an appropriate receiving method to eliminate the interference of the second signal to the first signal, thereby improving the receiving performance of the first signal.

[0127] As an optional embodiment, under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the first indication information is also used to indicate a relative power value between the first signal and the second signal.

[0128] The relative power value of the first signal and the second signal is used to represent the power difference between the first power and the second power in the direction in which the network device sends the second signal to the terminal device. The relative power value can be positive, negative, or zero, and the embodiment of the present application is not limited to this. The unit of the relative power value can be decibel (dB), but the embodiment of the present application is not limited to this.

[0129] Exemplarily, the relative value of the power of the first signal and the second signal may be 10 dB, indicating that in the direction in which the network device sends the second signal to the terminal device, the power of the second signal sent by the network device is 10 dB higher than the power of the first signal.

[0130] In order to better understand the relative power values ​​of the first signal and the second signal provided in the embodiment of the present application, an example is given to illustrate the relative power values ​​of the first signal and the second signal.

[0131] If the power of the first signal sent by the network device is P1, the power of the second signal sent is P2, the maximum antenna gain of the first signal sent by the network device is G1, and the maximum antenna gain of the second signal sent by the network device is G2, because the first signal sent by the network device will leak to the beam pointing direction of the second signal, the gain value of the beam used by the network device to send the first signal in the direction of the maximum antenna gain of the second signal is G3, then the difference between the power of the second signal and the power of the first signal here is: P2+G2-P1-G3. If the unit is a linear value, the difference between the power of the second signal and the power of the first signal can also be expressed as a power ratio, that is, P2*G2 / P1 / G3.

[0132] The first indication information is used to indicate a relative power value between the first signal and the second signal, and includes multiple possible implementation methods.

[0133] In a possible implementation, the first indication information may include a value, which is a relative power value of the first signal and the second signal. This implementation is simple and direct, and the terminal device can directly obtain the relative power value of the first signal and the second signal from the first indication information.

[0134] In another possible implementation, the first indication information may include multiple relative power values, one of which is the relative power value of the first signal and the second signal. In this case, the network device may also send another indication information to the terminal device, and the indication information is used to indicate the index value of the relative power value of the first signal and the second signal in the above multiple relative power values. Alternatively, the network device sends another indication information to the terminal device, and the indication information is used to indicate multiple relative power values ​​of the first signal and the second signal. The network device sends the first indication information to the terminal device, and the first indication information is used to indicate the index value of the relative power value of the first signal and the second signal in the above multiple relative power values. Among them, the multiple relative power values ​​can be called candidate values ​​of the relative power values, which is not limited in the embodiments of the present application.

[0135] Exemplarily, one indication information indicates multiple relative power values, such as 10 dB, 15 dB, and 20 dB, and the first indication information is used to indicate the index value of the relative power value of the first signal and the second signal in the multiple relative power values. In one example, the first indication information includes a field, which is used to indicate the index value of the relative power value of the first signal and the second signal in the multiple relative power values. For example, the field can be two bits, and the corresponding relationship between the values ​​of the two bits and the relative power values ​​can be as shown in Table 5.

[0136] Table 5

[0137] Bit value meaning 00 10dB 01 15dB 10 20dB 11 Reserve

[0138] As shown in Table 2, when the values ​​of the two bits are 00, it indicates that the relative power value is 10dB; when the values ​​of the two bits are 01, it indicates that the relative power value is 15dB; when the values ​​of the two bits are 10, it indicates that the relative power value is 20dB; when the values ​​of the two bits are 11, it indicates a reserved state.

[0139] This implementation indirectly indicates the relative power value of the first signal and the second signal through two indication information, which improves the security of information transmission compared with direct indication.

[0140] It can be understood that the above-mentioned first indication information can also be used to indicate whether the first signal in the first time period is associated with the second signal. In an example, the first indication information may include a field, which is used to indicate whether the first signal in the first time period is associated with the second signal, and is also used to indicate the index value of the relative power value of the first signal and the second signal in multiple power relative values. For example, the field is two bits, and the two bits are used to indicate whether the first signal in the first time period is associated with the second signal, and are also used to indicate the index value of the relative power value of the first signal and the second signal in multiple power relative values. Table 6 shows an example of two-bit indication information.

[0141] Table 6

[0142] Bit value meaning 00 The first signal is not related to the second signal 01 The first signal is associated with the second signal, 10dB 10 The first signal is associated with the second signal, 15dB 11 The first signal is associated with the second signal, 20dB

[0143] As shown in Table 6, when the values ​​of the two bits are 00, it indicates that the first signal is not associated with the second signal; when the values ​​of the two bits are 01, it indicates that the first signal is associated with the second signal, and the relative power value between the first signal and the second signal is 10dB; when the values ​​of the two bits are 10, it indicates that the first signal is associated with the second signal, and the relative power value between the first signal and the second signal is 15dB; when the values ​​of the two bits are 11, it indicates that the first signal is associated with the second signal, and the relative power value between the first signal and the second signal is 20dB.

[0144] In order to enable the terminal device to better remove interference from the second signal when demodulating the first signal, the network device can also send characteristic parameters of the second signal to the terminal device, such as the sequence of the second signal, the frequency domain coefficients of the second signal, and the time domain position of the second signal.

[0145] For example, Figure 5 A schematic flow chart of a communication method 500 provided in an embodiment of the present application is shown. The method 500 can be applied to the above Figure 2 The communication perception integration scenario shown in Figure 1 is as follows. Figure 5 As shown, the method 500 may include the following steps:

[0146] S501. The network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information, where the first indication information is used to indicate that a first signal within a first time period is associated with a second signal, wherein the first signal is used for communication, and the second signal is used for communication, perception or energy transmission or one or more thereof.

[0147] S502. The network device sends second indication information to the terminal device. Correspondingly, the terminal device receives the second indication information, where the second indication information is used to indicate at least one of a sequence of the second signal, a frequency domain coefficient of the second signal, or a time domain position of the second signal.

[0148] Under the condition that the first indication information is used to indicate that the first signal is associated with the second signal, the terminal device needs to consider removing the interference of the second signal when demodulating the first signal. The network device can indicate the characteristic parameters of the second signal to the terminal device through the second indication information, for example, at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal, so that the terminal device can remove the interference of the second signal when demodulating the first signal based on this information.

[0149] The second indication information is used to indicate at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal. In one example, the second indication information can be used to indicate the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal; in another example, the second indication information can be used to indicate two of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal; in yet another example, the second indication information can be used to indicate the sequence of the second signal, the frequency domain coefficient of the second signal, and the time domain position of the second signal. It can be understood that the more characteristic parameters of the second signal indicated by the second indication information, the more conducive it is for the terminal device to remove the interference of the second signal when demodulating the first signal.

[0150] S503: The network device sends a first signal and a second signal to the terminal device, and correspondingly, the terminal device receives the first signal and the second signal.

[0151] S504. The terminal device demodulates the first signal based on the first indication information and the second indication information.

[0152] Based on the first indication information, the terminal device can determine that there is an associated second signal with the first signal, and based on the second indication information, can determine at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal. When demodulating the first signal, the terminal device can remove interference caused by the second signal based on at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal.

[0153] In this implementation, the network device informs the terminal device of at least one of the sequence of the second signal, the frequency domain coefficient of the second signal, or the time domain position of the second signal through the second indication information, which is beneficial for the terminal device to better remove the interference caused by the second signal when demodulating the first signal.

[0154] In order to better understand the characteristic parameters of the second signal, they will be described in detail below.

[0155] 1) Sequence of the second signal

[0156] The sequence of the second signal may include N symbols, where N is an integer greater than 1. Each of the N symbols can be represented as a complex number, that is, x+j*y, where x is the real part and y is the imaginary part. The value of N is generally large, for example, the value of N can reach the order of several hundred. If the second indication information directly indicates the values ​​of the N symbols included in the sequence of the first signal, the number of information bits required for the second indication information will be large, and the overhead will be too large. Therefore, the network device and the terminal device can predetermine a candidate sequence set for the sequence of the first signal, and the candidate set can be several specific sequences or several input parameters for generating the sequence of the first signal, such as an initialization seed value. The network device can indicate the index of the sequence of the first signal in the candidate sequence set through the second indication information, or indicate the index of the input parameter for generating the sequence of the first signal in the candidate sequence set. The terminal device can determine the sequence of the first signal based on the second indication information and the candidate sequence set.

[0157] In a possible implementation, the network device and the terminal device may predetermine a candidate sequence set of the sequence of the first signal, and the candidate set includes several specific sequences, and the second indication information may be used to indicate the index of the sequence of the first signal in the candidate sequence set. For example, the candidate sequence set includes 10 sequences numbered from #0 to #9, and the second indication information may be used to indicate a value from #0 to #9, such as #5, indicating that the sequence of the first signal is the sequence numbered #5 in the candidate sequence set.

[0158] In another possible implementation, the network device and the terminal device may predetermine a candidate sequence set for the sequence of the first signal, and the candidate set includes several initialization seed values ​​for generating the sequence of the first signal, and the second indication information may be used to indicate the index of the initialization seed value for generating the sequence of the first signal in the candidate sequence set. For example, the candidate sequence set includes 10 initialization seed values ​​numbered from 0 to 9, and the second indication information may be used to indicate a value from 0 to 9, such as 5, indicating that the initialization seed for generating the sequence of the first signal is the initialization seed value numbered 5 in the candidate sequence set.

[0159] If the network device and the terminal device do not preset a candidate sequence set of the sequence of the first signal, the network device can indicate the initialization seed value of the sequence of the first signal through the second indication information, for example, the initialization seed value can be 100 or 1000, and the terminal device can obtain the initialization seed value based on the second indication information, and generate the sequence of the first signal based on the initialization seed value. In this implementation, the second indication information requires fewer information bits, which is simple and convenient.

[0160] 2) Frequency domain coefficients of the second signal

[0161] The frequency domain coefficients of the second signal can be used to preprocess the sequence of the second signal. Therefore, the frequency domain coefficients of the second signal can also be referred to as the preprocessing coefficients of the second signal. The embodiments of the present application do not limit this.

[0162] The frequency domain coefficients of the second signal can include M coefficients, and the sequence of the second signal can include N symbols, where M can be equal to N. Any one of the M coefficients can be a real number or a complex number. The embodiments of the present application do not limit this.

[0163] The m-th coefficient among the M coefficients can be denoted as a[m], the m-th symbol among the N symbols can be denoted as x[m], and the method for the frequency domain coefficients of the second signal to preprocess the sequence of the second signal can be y[m]=a[m]*x[m], where y[m] is the m-th symbol in the preprocessed second signal. In one example, both x[m] and y[m] can be represented as a complex number, including a real part and an imaginary part.

[0164] The second indication information is used to indicate the frequency domain coefficients of the second signal. In one example, the second indication information can indicate the M coefficients included in the frequency domain coefficients of the second signal. In another example, if there is a special rule for the M coefficients included in the frequency domain coefficients of the second signal, the second indication information can indicate the L coefficients included in the frequency domain coefficients of the second signal, where L is less than M.

[0165] Exemplarily, the M coefficients included in the frequency domain coefficients of the second signal satisfy that for a pre-determined positive integer k, k<M, for all coefficients with indices less than k: a[1], a[2], …, a[k−1], there is a[i]<a[i + 1], i<k; and at the same time, for all coefficients with indices greater than k: a[k + 1], a[k + 2], …, a[M], there is a[i]>a[i + 1], i>k. Or, the M coefficients included in the frequency domain coefficients of the second signal satisfy that for a pre-determined positive integer k, k<M, for all coefficients with indices less than k: a[1], a[2], …, a[k−1], there is a[i]>a[i + 1], i<k; and at the same time, for all coefficients with indices greater than k: a[k + 1], a[k + 2], …, a[M], there is a[i]<a[i + 1], i>k. Under this special rule, the second indication information can be used to indicate the k-th coefficient in the frequency domain coefficients of the second signal.

[0166] For example, M takes a value of 12, and the M coefficients may be {0.3, 0.35, 0.4, 0.45, 0.5, 0.6, 0.6, 0.5, 0.45, 0.4, 0.35, 0.3}, or {0.6, 0.5, 0.45, 0.4, 0.35, 0.3, 0.3, 0.35, 0.4, 0.45, 0.5, 0.6}. Under this special rule, the second indication information may be used to indicate the 6th coefficient and the 7th coefficient (i.e., 0.6 or 0.3) in the frequency domain coefficients of the second signal. For another example, when M is 24, the M coefficients may be {0.9, 0.8, 0.75, 0.7, 0.65, 0.6, 0.55, 0.5, 0.45, 0.4, 0.35, 0.3, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.9} or {0.9, 0.8, 0.75, 0.7, 0.65, 0.6, 0.55, 0.5, 0.45, 0.4, 0.35, 0.3, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.9}. Under this special rule, the second indication information may be used to indicate the 12th coefficient and the 7th coefficient (ie, 0.9 or 0.3) in the frequency domain coefficients of the second signal.

[0167] 3) Time domain position of the second signal

[0168] The time domain position of the second signal, that is, the position of the symbol occupied by the second signal in the time slot, can also be said to be the symbol position carrying the second signal in a time period, and the time period can be one or more time slots. The second signal can occupy one or more symbols in the time slot, which is not limited in the embodiments of the present application.
