In this embodiment of the present application, optionally, the relevant characteristic information of the sensing data includes at least one of the following:

1) The size of the sensing data to be transmitted;

Optionally, if the sensing data to be transmitted is a small amount of data, the sensing protocol stack can be based on the control plane. If the sensing data to be transmitted is a large amount of data, the sensing protocol stack can be based on the user plane.

2) Type of sensory data;

Optionally, the type of sensing data includes at least one of the following:

21) Perception request information;

The sensing request information is, for example, the sending node A requesting the receiving node B to assume a certain sensing function, where the sensing function may be sending sensing signals, receiving sensing signals, or processing sensing measurement results, etc. For example, SF requests base station A to assume the function of sending sensing signals, and SF requests UE B to assume the functions of receiving, measuring, and reporting sensing measurement results.

22) Perceive configuration information;

The sensing configuration information is used to indicate the configuration information of a certain sensing function, where the configuration information may include at least one of time-frequency domain resource configuration information of sensing signals, parameter configuration information for sensing measurement result transmission, and processing configuration information for sensing measurement results. item.

23) Perception auxiliary data;

Perception auxiliary data refers to data that assists perception, including at least one of the following:

Sensing data from other sensing devices, such as at least one of Global Positioning System (GPS) location information, cameras, lidar, etc.;

Perceive the prior information of the target, such as at least one of the radar cross-sectional area, breathing frequency range, some known environmental information in environmental reconstruction, etc.

24) Perceptual measurement results.

The sensing measurement result refers to the measurement result obtained after measuring the configured sensing signal. It can also be called sensing measurement. magnitude.

Optionally, the perceptual measurement results are divided into different levels according to the amount of information provided or the degree of processing:

The first-level measurement quantity (received signal or original channel information) includes: the complex result of the received signal or channel response, amplitude or phase, I-channel or Q-channel and its (I-channel or Q-channel) operation results, where the operation includes addition At least one of subtraction, multiplication and division, matrix addition, subtraction and multiplication, matrix transpose, trigonometric relation operation, square root operation and power operation, as well as threshold detection results of the above operation results, maximum/minimum value extraction results, etc.; the operation also includes fast Fourier Transform (Fast Fourier Transform, FFT)/Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT)/Inverse Discrete Fourier Transform Transform, IDFT), two-dimensional FFT (2D-FFT), three-dimensional FFT (3D-FFT), matched filtering, autocorrelation operation, wavelet transform and digital filtering, and at least one of the threshold detection results of the above operation results, Maximum/minimum value extraction results, etc.;

3) Perceive the information of measurement results;

Perception measurement results are usually a potentially large amount of data to be transmitted during the perception process.

For example, when the ratio of the channel response amplitude value in the target sensing delay interval to the amplitude value in other delay intervals is less than -5dB, it can be considered that the target has not been sensed this time. Then you only need to report that the target has not been sensed. Otherwise, you need to report the aforementioned First, second, third or fourth level measurement quantities to facilitate subsequent processing of perceptual measurement results.

Optionally, this information can also be used to determine whether the perceptual auxiliary data needs to be transmitted.

Correspondingly, the number of sensing nodes is smaller when the size of the sensing area is the same. If the UE serves as a sensing node, The corresponding number of sensing nodes required will increase slightly. When there are a large number of sensing nodes and each node transmits data in small packets, the design of the sensing protocol stack should minimize the number of transmission pipelines established by the sensing nodes and organize the data into appropriate locations to form packets with higher transmission efficiency. Make the transfer. For example, if there are multiple UEs serving as sensing signal receiving nodes, then the sensing data transmission method between the UE and the radio access network node can be considered.

The following is an example of the negotiation method of the sensing data transmission mode in the embodiment of the present application based on specific application scenarios.

Embodiment 1: A negotiation method for sensing data transmission mode between core network functions and terminals

In this embodiment, it is assumed that the sensing function (SF) is one of the core network network functions, and the UE receives the sensing signal and measures it (for example, the sensing method is: the base station sends the sensing signal and the UE receives it, the UE spontaneously receives it, and the UE transmits and receives it). Or, the UE provides sensing assistance data, that is, the UE locally needs to transmit sensing-related data to the network.

In this embodiment, the first device is SF, and the negotiation method of sensing data transmission mode includes the following steps:

Step 1: SF (the network function responsible for receiving sensing requests (sensing requests sent by the application layer or other functions) and/or providing sensing results, which can also be named by other names) receives the sensing request, which includes at least the following information One item:

1) Perception target area refers to the location area where the perception target object may exist, or the location area that requires imaging or three-dimensional reconstruction;

2) Perception target type. Classify the perception target object based on the possible motion characteristics of the perception target object. Each perception target object type contains information such as the motion speed, motion acceleration, typical RCS and other information of the typical sensing target object.

3) Sensing target objects. When one or more sensing target objects are sensed, the identification information of the sensing objects is provided. Potential identification methods include: feature identification on the distance, speed, angle spectrum or UE identifiable based on the network. ID identification.

4) Perception QoS, performance indicators for sensing the sensing target area or sensing target object, including at least the following One item: Perceptual resolution (which may further include: at least one of ranging resolution, angle measurement resolution, speed measurement resolution, and imaging resolution), etc., perception accuracy (which may further include: ranging accuracy, angle measurement accuracy , at least one of speed measurement accuracy, positioning accuracy, etc.), sensing range (which may further include: at least one of ranging range, speed measurement range, angle measurement range, imaging range, etc.), sensing delay (from sensing signal transmission The time interval to obtain the sensing result, or the time interval from the initiation of sensing demand to the acquisition of sensing result), sensing update rate (the time interval between two consecutive sensing executions and obtaining the sensing result), detection probability (when the sensing object exists) The probability of being correctly detected in the case), the false alarm probability (the probability of incorrectly detecting the sensing target when the sensing object does not exist).

Step 2: The SF determines the relevant feature information of the sensing data according to the sensing request, and determines the configuration information of the sensing data transmission mode based on the relevant feature information of the sensing data. In this embodiment, it is assumed that the UE is used as a sensing signal receiving and measuring node, the base station is a sensing signal sending node, and the SF is a processing node of sensing measurement results.

Relevant feature information of sensory data includes at least one of the following:

1) Type of sensing data, the type of sensing data includes at least one of the following:

Sensing request information, for example, SF requests base station A to assume the function of sending sensing signals, and SF requests UE B to assume the functions of receiving, measuring, and reporting sensing measurement results.

Sensing configuration information, for example, the SF negotiates with the base station for the time-frequency domain resource configuration of the sensing signal and sends it to the UE; the SF negotiates with the base station for the parameter configuration of sensing measurement result transmission and sends it to the UE.

Perception assistance data. For example, this perception service requires the UE's GPS location information and camera information to be reported as perception assistance data. The SF configures the UE to report the corresponding GPS location and camera data.

Perception measurement results, for example, after UE measurement, second-level measurement quantities (basic measurement quantities) are transmitted to and from the SF. The second-level measurement quantities include: delay, Doppler, angle, intensity, and their multi-dimensional combination representation.

2) The size of the sensing data to be transmitted. For example, SF determines the size or data size range of each type of sensing data mentioned above according to the sensing requirements.

3) Information about the sensing measurement results. For example, the information about the SF configuration sensing measurement results is the threshold information that needs to be transmitted for the sensing measurement results. That is, the UE usually performs preliminary calculations on the perception measurement results, and determines whether it meets the transmission requirements through the relationship between the calculation results and the threshold information. For example, the information on the perception measurement results can be the received signal signal-to-noise ratio/signal-to-dryness ratio, signal to clutter ratio, target The ratio of the perceived signal component to other perceived signal components, or the ratio of the channel response amplitude value in the target sensing delay interval to the amplitude value in other delay intervals. For example, when the ratio of the channel response amplitude value in the target sensing delay interval to the amplitude value in other delay intervals is less than -5dB, it can be considered that the target has not been sensed this time, and then it is only necessary to report that the target has not been sensed, otherwise it needs to be reported The aforementioned second-level measurement quantity is used to facilitate subsequent processing of perceptual measurement results. Optionally, this information can also be used to determine whether the perceptual auxiliary data needs to be transmitted. In one case, the perceptual auxiliary data is processed the same as the perceptual measurement results. If it needs to be transmitted, both the perceptual auxiliary data and the perceptual measurement results are transmitted; in the other case The situation is that when the sensing measurement results do not need to be transmitted, the sensing auxiliary data needs to be transmitted for SF to recheck the preliminary calculation results of sensing.

4) Number of sensing nodes. The sensing nodes include processing nodes for sensing signal transmission, reception and sensing measurement results. In this embodiment, it is assumed that there is only one base station as a sensing signal sending node and one UE as a sensing signal receiving node. If there are multiple UEs serving as sensing signal receiving nodes, then the sensing data transmission method between the UE and the radio access network node can be considered. The sensing data can be aggregated and processed on the radio access network side to improve transmission efficiency.

Step 3a: Through the existing sensing data transmission method between the SF and the UE (for example, the sensing protocol stack 1 between the UE and the SF), the SF sends the configuration information of the sensing data transmission method to the UE determined to participate in sensing, sensing data The configuration information of the transmission method includes at least one of the following:

1) The configured sensing data identifier; optionally, the sensing data identifier includes at least one of the following: a sensing data type identifier and a sensing service identifier. For example, the types of sensing data are sensing assistance data and sensing measurement result data. If the UE undertakes multiple sensing measurements, different sensing measurement results can be distinguished through measurement identifiers. If the UE has multiple sensing assistance data, then the sensing services can be distinguished. Identification, etc. to distinguish different perceptual auxiliary data.

2) Whether to use the indication information of the sensing protocol layer. The sensing protocol layer refers to the protocol that terminates between the sending node and the receiving node. The intermediate transmission node cannot parse the sensing protocol layer and only serves to transmit data. For example, the sensing protocol stack 2 between UE and SF uses the sensing protocol layer.

3) Instruction information of the transmission network protocol layer of the sensing data, used for the sensing data sending node and the receiving node to use the same transmission network protocol layer to transmit the sensing data. Indicates which transport network protocol layers are required based on what common protocol information the sending node and receiving node have. For example, in the sensing protocol stack 2 between UE and SF, the transmission network protocol layer of sensing data needs to be divided into UDP/IP and N3 interface protocol layer (GTP-U/UDP/IP), because the N3 interface protocol layer standard has been defined, so From top to bottom, it can be expressed as UDP, IP, and N3.

A protocol definition method can also be to jointly define the indication information of whether to use the sensing protocol layer and the indication information of the transmission network protocol layer of the sensing data as indication information of different sensing data transmission methods, such as the sensing protocol between the UE and the SF. Stack 1 is defined as mode 1, the sensing protocol stack 2 between UE and SF is defined as mode 2, the protocol option 1 between UE and RAN node is defined as mode 3, the control plane (CP) protocol between UE and RAN node is based on The option is defined as mode 4, the option based on the user plane protocol between the UE and the RAN node is defined as mode 5, and the indication information of the sensing data transmission mode can indicate which pre-agreed mode is used.

4) The transmission channel identification of the sensing data, such as PDU session ID, QoS flow ID, etc. If the configured sensing data needs to be transmitted on the specified transmission channel, then the transmission channel information needs to be configured. If there is no need to specify the transmission channel, then this item does not need to be configured. .

Wherein, the indication information of whether to use the sensing protocol layer and the indication information of the transmission network protocol layer of the sensing data are used to jointly indicate the sensing protocol stack.

Step 3b: If the configuration information of the sensing data transmission method includes multiple sensing protocol stacks, the SF can also determine the usage rules of the sensing data transmission method based on the relevant feature information of the sensing data obtained in step 2 and send it to the UE. The usage rules of the sensing data transmission method determine which sensing data transmission method is used. Optionally, the usage rules of the sensing data transmission mode are included in the configuration information of the sensing data transmission mode and are sent simultaneously with the configuration information of the sensing data transmission mode. The usage rules of the sensing data transmission mode can also be sent separately. For example, it can be sent through the existing transmission method between the SF and the UE (for example, the sensing protocol stack 1 between the UE and the SF).

Optionally, the usage rules of the sensing data transmission method include at least one of the following:

1) The configured sensing data identifier; optionally, the sensing data identifier includes at least one of the following: a sensing data type identifier and a sensing service identifier. For example, the types of sensing data are sensing assistance data and sensing measurement result data. If the UE undertakes multiple sensing measurements, different sensing measurement results can be distinguished through measurement identifiers. If the UE has multiple sensing assistance data, then the sensing services can be distinguished. Identification, etc. to distinguish different perceptual auxiliary data.

For example, in the sensing protocol stack 1 between the UE and the RAN node, the transmission network protocol layer of the sensing data is RRC (such as UE Information Response (UEInformationResponse)). Because the RRC signaling data transmission protocol layer standard has been defined, it only means RRC. .

The transmission channel identifier of the sensing data. If the configured sensing data needs to be transmitted on the specified transmission channel, then the transmission channel information needs to be configured, such as SRB2, etc. If you do not need to specify a transmission channel, you do not need to configure this item.

For example, the information on the perception measurement results can be the received signal signal-to-noise ratio/signal-to-dryness ratio, signal to clutter ratio, target The ratio of the perceived signal component to other perceived signal components, or the ratio of the channel response amplitude value in the target sensing delay interval to the amplitude value in other delay intervals. For example, when the ratio of the channel response amplitude value in the target sensing delay interval to the amplitude value in other delay intervals is less than -5dB, it can be considered that the target has not been sensed this time, and then it is only necessary to report that the target has not been sensed, otherwise it needs to be reported The aforementioned second-level measurement quantity is used to facilitate subsequent processing of perceptual measurement results. Optionally, this information can also be used to determine whether the perceptual auxiliary data needs to be transmitted. In one case, the perceptual auxiliary data is processed the same as the perceptual measurement results. If it needs to be transmitted, both the perceptual auxiliary data and the perceptual measurement results are transmitted; in the other case The situation is that when the sensing measurement results do not need to be transmitted, the sensing auxiliary data needs to be transmitted for SF to recheck the preliminary calculation results of sensing.

Then the indication information of the sensing data transmission mode can indicate which method to use. A pre-agreed way.

The base station can The usage rules of the sensing data transmission method determine which sensing data transmission method is used. Optionally, the usage rules of the sensing data transmission mode are included in the configuration information of the sensing data transmission mode and are sent simultaneously with the configuration information of the sensing data transmission mode.

Embodiment 3: A negotiation method for sensing data transmission mode between the radio access network function and the UE

In this embodiment, it is assumed that the radio access network function is responsible for the negotiation and configuration of the UE sensing data transmission method, the situation where the UE receives and measures the sensing signal (such as the base station sending the sensing signal and the UE receiving it, the UE spontaneously receiving it, and the UE transmitting and receiving it), or The UE provides sensing assistance data, that is, the UE locally needs to transmit sensing-related data to the network.

In this embodiment, the first device is a wireless access network function (such as RRC, etc.), and the negotiation method of sensing data transmission mode includes the following steps:

Step 2: The SF determines the RAN node participating in sensing according to the sensing request. The node may be a sensing signal sending node, a sensing signal receiving node, or a sensing measurement result processing node, etc. The selected RAN node determines whether the UE is required to participate in sensing. Take the UE as a sensing signal receiving and measuring node, the base station as a sensing signal sending node, and the SF as a processing node for sensing measurement results as an example.
