The received electromagnetic waves can be the echo of the electromagnetic waves emitted by the communication device itself, or they can be electromagnetic waves actively emitted by other objects.

[0003] However, there is some overlap between the communication function and the perception function of the communication device. The duplication of overlapping functions will increase the signaling overhead and increase the power consumption of the device. Summary of the invention

[0031] As described in the background technology, there is some overlap between the communication function and the perception function of the communication device. The repetition of overlapping functions will increase the signaling overhead and increase the power consumption of the device.

[0032] In the technical solution of the present invention, the communication device can determine the target information or channel information of the perception operation, and select a signal to send when the perception operation and the communication operation are concurrent. Compared with sending two signals, the perception signal and the measurement reference signal, the technical solution of the present invention can meet the perception requirements of the perception operation and the communication requirements of the communication operation on the basis of sending only one signal, reduce signaling overhead, and improve user experience.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Figure 1 The present invention is a flow chart of a communication method according to an embodiment of the present invention.

[0035] The communication method can be used on the network device side or on the terminal device side. When the communication method is used on the network device side, the communication operation is a downlink operation, such as downlink transmission; when the communication method is used on the terminal device side, the communication operation is an uplink operation, such as uplink transmission.

[0036] Specifically, the communication method may include the following steps:

[0037] Step 101: Determine target information or channel information of a sensing operation;

[0038] Step 102: When the sensing operation and the communication operation are performed concurrently, determining a target signal to be sent according to the target information or the channel information, where the target signal includes a sensing signal or a measurement reference signal.

[0039] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0040] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, and the software program runs in a processor integrated inside a chip or a chip module.

[0041] In this embodiment, the concurrency of the perception operation and the communication operation may refer to executing the perception operation and the communication operation at the same time, or may refer to executing the perception operation and the communication operation within a period of time with a preset time length.

[0042] The perception operation referred to in this embodiment may refer to a series of actions in which the communication device sends a perception signal to perceive surrounding target objects.

[0043] The communication operation referred to in the embodiment of the present invention may refer to an action related to a communication device sending a communication signal, such as signaling or data.

[0044] The sensing signal referred to in the embodiment of the present invention refers to a signal used for sensing operation.

[0045] The measurement reference signal referred to in the embodiment of the present invention refers to a reference signal used for positioning or channel estimation in a communication operation, for example, it may be a positioning reference signal (PRS) or a sounding reference signal (SRS).

[0046] In the specific implementation of step 101, when the communication device performs the sensing operation, it can obtain the purpose of the sensing operation, that is, it can obtain the target information of the sensing operation. Specifically, when the purpose of the sensing operation is distance measurement, the target information is the distance; when the purpose of the sensing operation is angle measurement, the target information is the angle; when the purpose of the sensing operation is speed measurement, the target information is the speed; when the purpose of the sensing operation is imaging, the target information is imaging information, such as an image or video of the target object.

[0047] Those skilled in the art will appreciate that the target information of the sensing operation may also be any other feasible information type, and the embodiments of the present invention are not limited to this.

[0048] In the specific implementation of step 101, when performing the sensing operation, the communication device may also obtain channel information of the sensing operation, which may specifically be relevant information of the channel used by the sensing operation.

[0049] In the specific implementation of step 102, when the sensing operation and the communication operation are performed concurrently, the communication device may determine the target signal to be sent according to the target information, or may determine the target signal to be sent according to the channel information. The target signal is one of the sensing signal and the measurement reference signal.

[0050] Compared with the need to send two signals, a perception signal and a measurement reference signal, in conventional operations, the embodiments of the present invention can meet the perception requirements of perception operations and the communication requirements of communication operations while sending only one signal, thereby reducing signaling overhead and improving user experience.

[0051] In a non-limiting embodiment, when the target information is positioning information, the target signal is determined to be the measurement reference signal.

[0052] Furthermore, the positioning information includes distance, angle and / or speed.

[0053] Specifically, please refer to Figure 2 , a network device is a device that performs sensing operations.

[0054] Step 201: The network device determines target information or channel information of a sensing operation.

[0055] Step 202: The network device sends a target signal.

[0056] In a specific embodiment, the network device determines that the target information is positioning information, and the network device sends a positioning reference signal.

[0057] In this embodiment, since the target information is positioning information, and the positioning reference signal in the communication operation can also complete the positioning function, the network device can send the positioning reference signal when the sensing operation and the communication operation are concurrent, and there is no need to send the sensing signal. In addition, since the frequency band occupied by the sensing signal is wider than that of the positioning reference signal, and the transmission period of the sensing signal is shorter than that of the positioning reference signal, sending the positioning reference signal in the above case can also reduce resource overhead.

[0058] Specifically, the network device can use the positioning reference information to complete the perception operation.

[0059] In another specific embodiment, the network device determines that the target information is imaging information, and the network device sends a perception signal.

[0060] In this embodiment, since the target information is imaging information, which is more complex and has higher requirements than other target information such as distance, speed, etc., the network device needs to send a perception signal at this time, and does not need to send a positioning reference signal.

[0061] Specifically, the network device can use the sensing signal to complete the positioning function in the communication operation. That is, in this case, the role of the sensing signal is equivalent to that of the positioning reference signal.

[0062] In another specific embodiment, the network device determines channel information for the sensing operation. The network device may also determine channel information for the communication operation. The network device calculates the correlation between the channel used for the communication operation and the channel used for the sensing operation, and when there is a correlation between the two, preferably sends the sensing signal without sending the positioning reference signal and the channel state information (CSI) reference signal.

[0063] In a specific implementation, the correlation between the channel used for the communication operation and the channel used for the sensing operation means that the two channels are adjacent and have similar channel characteristics, so when the state of one channel is known, the state of the other channel is equivalent to knowing. For example, the two channels are in close proximity within the frequency domain bandwidth.

[0064] In an embodiment of the present invention, when the above two channels are related, the network device can avoid sending a channel state information reference signal by sending a perception signal. At the same time, the terminal device may no longer calculate the channel state information and report the channel state information report, thereby further reducing the signaling overhead.

[0065] In an optional embodiment, when a channel used by a communication operation is correlated with a channel used by a sensing operation, the network device may also send a positioning reference signal instead of sending a sensing signal.

[0066] Specifically, please refer to Figure 3 , the terminal device is a device that performs sensing operations.

[0067] Step 301: The network device determines target information or channel information of a sensing operation.

[0068] Step 302: The network device sends a target signal.

[0069] In a specific embodiment, the terminal device determines that the target information is positioning information, and the terminal device sends a sounding reference signal.

[0070] In this embodiment, since the target information is positioning information, and the sounding reference signal in the communication operation can also complete the positioning function, the terminal device can send the sounding reference signal when the sensing operation and the communication operation are concurrent, and there is no need to send the sensing signal. In addition, since the frequency band occupied by the sensing signal is wider than that of the sounding reference signal, and the transmission period of the sensing signal is shorter than that of the sounding reference signal, sending the sounding reference signal in the above situation can also reduce resource overhead.

[0071] Specifically, the terminal device can use the positioning reference information to complete the perception operation.

[0072] In another specific embodiment, the terminal device determines that the target information is imaging information, and the terminal device sends a perception signal.

[0073] In this embodiment, since the target information is imaging information, which is more complex and has higher requirements than other target information such as distance, speed, etc., the terminal device needs to send a perception signal at this time, and does not need to send a detection reference signal.

[0074] Specifically, the terminal device can use the sensing signal to complete the channel estimation function in the communication operation. That is, in this case, the role of the sensing signal is equivalent to that of the sounding reference signal.

[0075] Further, Figure 3 The communication method shown may further include step 303: obtaining channel information using the sensing signal, and calculating a precoding matrix according to the channel information.

[0076] In a specific implementation, the terminal device can obtain the channel information between the terminal device and the network device based on the perception signal: H1×H2'. Among them, H1 represents the channel state information between the terminal device and the network device, such as the base station, and H2 represents the channel state information between the base station and the terminal device. When there is a correlation between the uplink and downlink channels, it can be considered that H1=H2', where H2' represents the conjugate transposed matrix of H2. By performing eigenvalue decomposition on H1×H2', the corresponding eigenvector group is obtained. The eigenvector group can contain one or more eigenvectors. The terminal device can determine which eigenvector groups to use as its uplink precoding transmission according to the rank of its transmission. The above method can be used as a new uplink transmission mode.

[0077] In an embodiment of the present invention, the terminal device can calculate the precoding matrix by sensing the signal, thereby eliminating the need for the network device to specify the TPMI (Precoding Matrix Indicator, PMI) and the sounding reference signal resource indication set (SRS Resource Index, SRI), further reducing the signaling overhead.

[0079] A determination module 401 is used to determine target information or channel information of a sensing operation;

[0080] The sending module 402 is used to determine a target signal to be sent according to the target information or channel information when the sensing operation and the communication operation are performed concurrently, where the target signal includes a sensing signal or a measurement reference signal.
