Detailed ways

In recent years, the research field of wireless sensing technology has attracted more and more attention. This technology can extract specific information or characterize the occurrence of a certain behavior by detecting changes in certain characteristics (such as phase, power, eigenvalues, etc.) of the received wireless signal. To meet expected services or assist in achieving more efficient communication transmission. This makes wireless sensing technology widely used in non-touch control (such as recognizing gestures), elderly monitoring (such as detecting falling movements), health monitoring (such as detecting heartbeat and breathing), weather detection (such as identifying the amount of rain and snow), UAV (unmanned aerial vehicle, drone) detection (such as illegal flying object detection), environmental monitoring (such as dangerous event alarm) and assisted intelligent transportation and other application scenarios.

This application proposes to utilize the wireless communication capabilities of the SparkLink Alliance system (hereinafter collectively referred to as the SparkLink system) as described in the background section to meet the sensing signal and sensing requirements in different wireless sensing application scenarios listed above. Results and other information transmission needs. In order to meet the needs of flexible and diverse wireless sensing services, the Starlight system can enhance related functions at the air interface level. Therefore, based on the characteristics of sensing services, this application designs a series of signaling and interaction processes between service nodes based on the air interface standard of the Star Flash system, which can mainly include resource coordination signaling on the air interface to support the sending and receiving of sensing signals. In addition, High-level signaling related to the basic service layer such as service establishment and sensing calibration is also considered. The combination of these signaling can flexibly support various existing wireless sensing architectures to meet sensing business needs.

For example, referring to the structure of the Starlight Alliance system that supports perception functions as shown in Figure 1, the basic unit of perception services can be introduced in the basic application layer of the system so that it can target different perception services such as gesture recognition and motion capture. , carry out business description and general behavior definition. And in the basic service layer, a perception control unit and a perception data unit can also be introduced. The perception control unit performs resource coordination with the existing communication devices of the Starlight system and transmits and processes perception control signaling. The perception data unit receives information for perception. The measurement data is analyzed and processed to obtain the sensing results corresponding to the sensing business.

In addition, in order to support sensing services, the access layer of the Star Flash Alliance system adds a link control layer and a media access layer, as shown in Figure 1, which can be based on the existing ultra-low latency support of the Star Flash 1.0 air interface standard. In both version (Sparklink Basic, SLB) and low-power version that supports low-power transmission (SparkLink Low-Energy, SLE), the link control layer and media access layer are introduced to enhance sensing capabilities and ensure signaling and For the transmission and implementation process of the corresponding signal, please refer to the description of the corresponding parts of the embodiment below, and this embodiment will not be described in detail here.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Combined with the above description of the technical solution of the present application and the system structure shown in Figure 1, in order to clearly describe the implementation of the wireless sensing function in the starlight system, the above sensing service can be implemented in any service node of the system. Basic functional unit, which can implement corresponding roles based on different functions and behaviors implemented in the sensing service process, such as sensing requester/node, sensing responder/node, sensing sender/node and sensing receiver/node. Signaling combination. The following will describe the sensing service processing method and process performed by different types of service nodes included in the StarLight system when they are combined as different roles, including but not limited to the content described in the embodiments below.

Referring to Figure 2, a schematic flow chart of an optional example of the sensing service processing method proposed in this application is shown. In this embodiment, the management node G-Node (denoted as the first service node) and the managed node T included in the Star Flash system -Node (i.e., the second service node) performs interactive implementation. In this embodiment, the first service node The implementation process is described on the service node side. In practical applications, the first service node can access at least one second service node, and is responsible for coordinating communications between different accessed second service nodes, as well as between the accessed second service node and itself, to implement the process. The application is not detailed.

Therefore, the perception service processing method described in the embodiments of this application can be based on the perception architecture composed of two or more service nodes of the Star Flash system. The multiple service nodes coordinate to complete the perception service, and in the form of interactive transmission and reception (i.e. perception The sending end and the sensing receiving end are located at different service nodes) for sensing, but this application does not elaborate on the structural relationship of this sensing architecture, and the sensing requesting end of the sensing service can be the first service node or the second service Nodes, depending on the situation.

Combined with the above analysis, as shown in Figure 2, the perceptual service processing method proposed in this embodiment may include but is not limited to the following steps:

Step S21: Send a sensing transmission resource indication for the requested sensing service to the second service node according to the sensing service request;

In this embodiment of the present application, the sensing service request may be a service node belonging to the sensing requesting end of the requesting sensing service this time, such as being triggered by a related application located in the service layer of the first service node or any second service node. The service request can usually include description information related to the sensing service, such as sensing service type, service quality requirements, etc., which triggers subsequent sensing processes. This application does not impose any restrictions on the trigger generation method of the sensing service request and its content, which may be determined based on the circumstances.

Combined with the above description of the sensing service request, if the first service node serves as the sensing requester, under different sensing services, after the corresponding first application in the service layer triggers the sensing service request, the first service node can Query, select and negotiate response nodes that can participate in and provide sensing services within the sensing range (i.e., the sensing responder of this sensing service). During the negotiation process, the sensing requesting end can send requests to the sensing node based on sensing service requirements and environmental conditions. The sensing response node (such as the second service node serving as the sensing response end) negotiates and determines the wireless resources required for the sensing signal, such as time, bandwidth, transmission power, etc.

In some embodiments, if the sensing requester for a certain sensing service is a second service node, and the sensing service request is triggered by the second application located in the service layer corresponding to the second service node, the second service node serves as the managed The node usually needs to send a sensing transmission resource application to the first service node corresponding to the sensing range to which it belongs, and accordingly negotiate with the first service node the wireless resources for sensing expected by the second service node. The implementation process can be referred to below. Description of the corresponding parts of the embodiment.

It can be seen that the above-mentioned sensing service request can be triggered by the sensing requesting node as the sensing requesting end and the corresponding application in the service layer. The sensing requesting node can be the first service node or the second service node. For different types of sensing requesting ends and / Or for sensing service requests with different request content, the sensing process to complete this sensing service may be different, but it usually requires negotiation between the sensing requester and the sensing responder to determine the wireless resources required for the sensing signal, and then the sensing signal is determined by The management node in the system sends a sensing transmission resource indication for the requested sensing service to the managed node. The indication can be broadcast or unicast. This can be determined based on the request content such as the sensing service type included in the sensing service request.

Wherein, the above-mentioned cognitive transmission resource indication may be to define new G link control signaling in the starlight system, and the control signaling indicates the wireless resources including time and frequency band that can be used by the selected sensing response node, That is, the wireless resources used by the second serving node for sensing services can be determined through the cognitive transmission resource indication sent by the first serving node.

In this regard, this application can introduce G link control information predefined for sensing services (that is, a new type of G link control information that is different from traditional communication link control information) into the existing air interface standard SLB of the Starlight system. , and introduce the physical layer control information predefined for the sensing service into the existing air interface standard SLE to realize the definition of the new G link control signaling. The implementation process will not be described in detail in this application. It should be understood that the control information introduced by the air interface standard may include but is not limited to predefined sensing signal transmission formats, transmission characteristics, broadcast identifiers, given time/frequency, receiving/transmitting sensing signals and other sensing-related information. Determine the contents of the new G link control information and physical layer control information based on the actual situation.

As analyzed above, in the process of establishing a sensing service as described above, since the sensing responder is a service node that responds to sensing service requests, it can take corresponding sensing-related operations based on the requested service type and service requirements, such as sensing signals. Send or receive etc. For a certain sensing service request, there may be multiple sensing responders within the sensing range of the sensing requester, which may be determined when the sensing service request is triggered, or may be selected and determined by the first service node within its sensing range. This application provides There are no restrictions on the number of sensing responders and service node types for any sensing service request. And it can be understood that the second service node in step S21 may refer to one or more second service nodes within the sensing range of the first service node, and may be determined based on the content of the sensing service request. This application does not limit this.

Therefore, in the actual application of sensing services, this application does not limit the type of service node (such as the first service node or the second service node) of the sensing request end of the sensing service request. No matter what sensing application scenario, it is usually used as The management node of the StarLight system, that is, the first service node, sends the corresponding sensing transmission resource indication to one or more second service nodes within its sensing range, so that the second service node knows that it can be used in this sensing service. wireless resources in order to perform subsequent sensing processes accordingly.

Among them, the sensing range of the first service node can be a spatial area formed by taking the location of the first service node as the center and radiating to the surroundings until the maximum distance it can sense. This can be based on the sensing performance of the first service node. Determined by factors such as the sensing environment where they are located, this application does not limit the sensing ranges of different first service nodes.

Step S22: Send a cognitive wireless frame to the corresponding second service node according to the wireless resource, and the second service node processes the cognitive wireless frame to obtain a sensing result for the cognitive service;

In the embodiment of this application, the sensing transmitter may refer to a node that sends a wireless signal for sensing (i.e., sensing signal). The wireless signal may reuse the existing starlight air interface signal waveform and reference signal, or may be a newly designed one. The air interface signal waveform or reference signal is not described in detail in the embodiments of this application regarding the functional implementation of the air interface signal waveform and reference signal in communication applications. Among them, the transmission format of the sensing signal, such as time, frequency and power, can be determined by the sensing control function in the basic service layer of the StarLight system based on the service requirements in the sensing service request.

Correspondingly, the sensing receiver may refer to a node that receives and processes sensing signals. The signal processing method for sensing signals may be determined by the sensing control function in the basic service layer based on the service requirements in the sensing service request, such as obtaining channel status. Information or average power of received signals, etc., the embodiments of this application will not list them one by one here.

It should be understood that for a certain sensing service request, there may be multiple sensing senders within the sensing range, and both the first service node and the second service node may serve as sensing senders. In practical applications, the identity of the service node in this sensing service can be determined based on the sensing transceiver function and other information of each service node (which can be the sensing requester or sensing responder of this sensing service), such as Sensing sender or sensing receiver.

In the embodiment of this application, the identity of the first service node as the sensing sender of this sensing service is taken as an example. According to the method described above, it is determined that the second service node is used for this sensing service. After receiving the wireless resource of the service, the first serving node may send the cognitive wireless frame to the corresponding second serving node according to the wireless resource. Among them, this application can pre-define the wireless frame used for sensing in the starlight system, that is, the sensing wireless frame, which can include the sensing signal described above. Therefore, its control instruction indicates to the second service node as the sensing response node that the sensing wireless frame is used for sensing signals. The sensing wireless frame with the newly defined T link control information can be introduced in the SLB and can be introduced in the SLE. A cognitive radio frame with newly defined physical layer control information. Therefore, the above-mentioned cognitive radio frame includes predefined link control information and physical layer control information for the cognitive service introduced by the access layer of the wireless communication system.

In some embodiments, during the process of establishing a sensing service between the first service node and the second service node, the sensing service request may be based on the sensing service type and service requirements contained in the sensing service request, from within the sensing range of the first service node. Among the second service nodes, select one or more second service nodes. For example, you can select a second service node nearby within the sensing range, or you can select based on information such as the equipment type and function of each second service node. Of course, in actual applications, any or all second service nodes within the sensing range of the first service node can also be selected by default. The embodiment of this application provides a method for selecting a second service node that establishes sensing service with the first service node. There are no restrictions on implementation methods.

Based on this, the first service node may send the corresponding cognitive radio frame to the selected second service node according to the radio resources used for the cognitive service by the second service node. It can be understood that if the wireless resource contents used by the second service nodes for sensing services are different, the contents of the cognitive radio frames sent by the first service node to the second service nodes may also be different, depending on the situation. In this embodiment No details will be given here.

Step S23: When the second service node does not belong to the sensing requester of the sensing service, receive the sensing result fed back by the second service node.

Following the above description, this application obtains the desired sensing information through changes in the wireless propagation environment, and obtains sensing results that satisfy the sensing service. After any second service node as the sensing receiving end of this sensing service receives the sensing wireless frame, it can According to the signal processing method determined based on the service requirements of this sensing service, the sensing signal contained in the sensing wireless frame is processed, and the required sensing results are obtained based on the characteristic changes of the sensing signal. The signal processing implementation process can implement the air interface of the StarLight system. The protocol enhancement and implementation process will not be described in detail in this application.

After any second service node obtains the sensing result of this sensing service, if the second service node belongs to the sensing requester of this sensing service, it can indicate the end of the sensing process of this sensing service request, which can be done by the second sensing requester as the sensing requester. The service node sends stop-sensing signaling to each sensing responder. The stop-sensing signaling of this node can reuse or extend the service management function at the basic service layer in the existing StarLight system.

If the second service node does not belong to the sensing requester of this sensing service, the sensing receiving end needs to report the sensing result of this sensing service to the sensing requesting end. In this embodiment, the second service node of the sensing responder can The obtained sensing results are fed back to the first service node, so that the first service node can receive the sensing results fed back by the second service node belonging to the sensing responder. At this time, if the first service node is the sensing requester, this sensing service can be ended. If the first service node is also the sensing responder and some other second service node is the sensing requester, the first service node can receive the sensing request. The sensing results are reported to the second service node as the sensing requester.

It can be seen that in a sensing service, the service node belonging to the sensing receiving end will report the obtained sensing result for the sensing service directly or through the first service node (when it does not belong to the sensing requesting end) to the sensing requesting end. The implementation process of the embodiments of this application will not be described in detail here. Among them, for the reporting and transmission of sensing results, the existing StarLight system standard physical layer transmission channel can be reused or expanded, or a new transmission channel can be defined for sensing services to realize transmission between the first service node and the second service node. .

Referring to Figure 3, a schematic flow chart of another optional example of the perception service processing method proposed in this application is distinguished. Different from the above embodiment in which the first service node participates in the perception service as the perception sender, in this embodiment, the first service node The node will participate in the sensing service as a sensing receiver. As shown in Figure 3, the sensing service processing method described from the first service node side may include:

Step S31: Send a sensing transmission resource indication for the requested sensing service to the second service node according to the sensing service request;

Among them, the first service node and the second service node conduct interactive negotiation, and the determined cognitive transmission resource indication can determine the wireless resources corresponding to the second service node used for this sensing service, such as time, frequency band, etc. This application does not use wireless resources. There is no restriction on the information content to ensure that the second service node can reliably complete this sensing service according to the wireless resources. Regarding the determination and issuance of perceptual transmission resource indications For the sending process, reference may be made to the description of the corresponding parts of the above embodiment, and no further description will be given in this embodiment. And the first service node can implement the selection of the responding second node in the perceptual service management function according to the method described above.

Step S32: Receive the cognitive radio frame sent by the second service node according to the corresponding wireless resource to process the cognitive radio frame and obtain the sensing result for the cognitive service;

Step S33: If the second service node belongs to the sensing requester of the sensing service, the sensing result is sent to the second service node.

In this embodiment, if the first serving node serves as a sensing receiver, especially if it only has a sensing signal receiving function and does not have a sensing signal sending function, it negotiates with the second serving node to determine the wireless resources used for sensing services. Afterwards, the second service node can send a cognitive wireless frame; of course, if the first service node has the function of sending and receiving cognitive signals, it can also serve as a perception receiver, and the second service node sends unicast signals to the devices within its sensing range in a unicast manner. The first service node sends a cognitive radio frame.

It should be noted that, unlike the content of the cognitive wireless frame sent by the first service node in the above embodiment, the cognitive wireless frame sent by the second service node in this embodiment can be included in the The newly defined T link control information introduced in SLB, and the newly defined physical layer control information introduced in SLE. The sensing signals contained in the sensing radio frame and the indication function of the control signaling, as well as the information types contained in the newly defined control information are similar, and will not be described in detail here in the embodiments of the present application.

Regarding the implementation process of obtaining the sensing service after the first service node receives the sensing wireless frame, the relevant description of the second service node processing the sensing signal to obtain the sensing result can be followed above. And when the first service node belongs to the sensing requester of this sensing service, the sensing result does not need to be transmitted externally. If the first service node belongs to the sensing responder of this sensing service, and a certain second service node belongs to the sensing requester of this sensing service, the first service node needs to send the obtained sensing result to the sensing result through unicast. For the second service node, regarding the transmission implementation method of the sensing result, please refer to the description of the corresponding part of the above embodiment.

In some embodiments proposed in this application, for the above-mentioned step S21 and step S31, different processes are performed on different sensing requesting terminals of this sensing service. For example, if the first service node is For the sensing requester of this sensing service, this step may include: sending a sensing transmission resource indication for the requested sensing service to the second service node based on the sensing service request triggered by the first application of the first service node located in the service layer, In this case, the first service node serves as the sensing requester and the sensing sender, and the second service node serves as the sensing responder and sensing receiver, resulting in a sensing architecture as shown in Figure 4a. The first service node and the second service node Nodes can negotiate and indicate the wireless resources used for sensing services. According to several signaling and sensing signal transmissions shown in Figure 4a, unicast mode is used to complete this sensing service. The process is as follows:

The first service node may send a corresponding sensing transmission resource indication to the second service node; the first service node may send a sensing wireless frame to the second service node, and the second service node processes the sensing wireless frame to obtain the sensing radio frame for this time. The sensing result of the service; the second service node sends the sensing result to the first service node.

It should be noted that the second service node in Figure 4a can be any second service node selected by the first service node in the sensing service management function; of course, in conjunction with the above description, multiple second service nodes can also be selected as sensing service nodes. At the receiving end, each second service node can complete the sensing service according to the sensing process shown in Figure 4a. At this time, the first service node can feedback the sensing results for the same sensing service received from different second service nodes. Analyze and obtain the final sensing result of the sensing service. The implementation process will not be described in detail.

In some embodiments, combined with the description of the embodiment shown in Figure 3 above, the first service node can also serve as the sensing requester and sensing receiver, and at least one second service node can serve as the sensing responder and sensing sender, such as In another sensing architecture shown in Figure 4b, the first service node uses unicast mode to send a sensing transmission resource indication to the second service node, and the first service node receives the sensing wireless frame sent by the second service node in unicast mode. , detect the sensing signal to obtain the sensing result. It can be seen that when the first service node serves as a sensing requester, it can serve as a sensing receiver or sensing sender, receive or send sensing wireless frames, obtain the sensing result of this sensing service, and complete a sensing service.

It should be noted that under the sensing architecture shown in Figure 4a and Figure 4b, only the sensing process between the first service node and one second service node within its sensing range is shown. For the first service node and multiple identical The sensing process between the second identity service nodes is similar, and this application does not give examples one by one. In this case, the first service node can process each obtained sensing result for this sensing service, such as deduplication, etc., to obtain the final sensing result of this sensing service.

In some embodiments, if the first service node selects multiple second service nodes as sensing responders, the sensing process between the first service node and any second service node can adopt the above figure 2 or Any perception service processing method shown in Figure 3 is combined to obtain a new perception service processing method under a new perception architecture.

For example, assuming that the first service node as the sensing requester of this sensing service serves as the sensing receiver and the sensing sender at the same time, for different second service nodes, within the sensing range of the first service node, Select the second service node as the sensing sender of this sensing service, and another second service node as the sensing receiving end of this sensing service, to obtain another sensing architecture as shown in Figure 4c. Based on this, the first service The node can coordinate the wireless resources of multiple second service nodes for sensing services, and complete this sensing service according to but not limited to the sensing process shown in the following paragraph:

As shown in Figure 4c, the first service node uses unicast mode to send the sensing transmission resource indication to each selected second service node. After that, the first service node can send the corresponding sensing transmission resource indication to one of the second service nodes. wireless frame (for its sending process, please refer to the description of the corresponding part of the embodiment shown in Figure 2), and the selected second serving node can send a cognitive wireless frame to the first serving node (for its implementation process, please refer to the description shown in Figure 3 (Description of the corresponding part of the embodiment), it can be seen that for second service nodes with different identities, the control information contained in the sent or received sensing wireless frames is different, which may depend on the type of the service node of the sensing sender. This embodiment will not do this here. Repeat.

Afterwards, the first service node receives the cognitive wireless frame sent by the second service node belonging to the sensing sender (the second service reception on the left side of Figure 4c), and sends it to the second service node belonging to the sensing receiver (the right side of Figure 4c). The second service node) sends the cognitive wireless frame, and the second service node sends the sensing result obtained by the processing to the first service node. The first service node can process the received cognitive wireless frame and the second service belonging to the sensing sending end. The sensing results fed back by the nodes are processed to obtain the sensing results for the sensing service. That is to say, the first service node will synthesize the sensing signals received by itself and the sensing results fed back by some second service nodes to obtain the final sensing results, realizing There are no restrictions on the process.

In some embodiments proposed in this application, if the second service node is the sensing requester of this sensing service, the second service node needs to apply for sensing wireless resources from the first service node and trigger The first service node sends a sensing signal, and the sensing result is directly obtained by receiving the sensing signal sent by the first service node. Among them, the application for sensing transmission resources sent by the second service node to the first service node through unicast mode may be the new T link control signaling defined in the Starlight system (that is, for the second service node Control signaling newly defined by the basic air interface layer), which includes wireless resources such as time and frequency band expected by the second service node for sensing services. New T link control information can be introduced in SLB and SLE respectively. and physical layer control information are implemented. In this way, after the first service node receives the cognitive transmission resource application, it can negotiate with the corresponding second service node to determine the wireless resources that the second service node can use.

Therefore, in this embodiment of the present application, the above-mentioned application for cognitive transmission resources may be sent based on the cognitive service request triggered by the second application of the second service node located in the service layer, and can indicate other devices located within the sensing range of the first service node. Whether the second service node responds to the requested sensing service, that is, whether the second service node, as the sensing requester, also wants more second service nodes within the sensing range to assist it in better completing the sensing service. If necessary, you can The description is defined in the cognitive transmission resource application, so that the first service node can negotiate with each second service node participating in this cognitive service respectively to determine the wireless resources used for the cognitive service based on the received cognitive transmission resource application.

Afterwards, the first service node may send a sensing transmission resource indication for the requested sensing service to the second service node that made the application and other indicated second service nodes that respond to the sensing service. It can be understood that if assistance from other second service nodes is not required, the first service node can directly send the perceptual transmission resource indication to the second service node that made the application.

Therefore, when any second service node serves as the sensing requester of this sensing service, the first service node corresponding to its sensing range, or even other second service nodes within the sensing range, serves as the sensing responder of this sensing service. Under the sensing architecture, if the second service node of the sensing requesting end serves as the sensing receiver, the first service node corresponding to the sensing range of the second service node serves as the sensing sender. As shown in Figure 5a, another sensing architecture can be based on The following signaling and sensing signal transmissions use unicast to complete this sensing service:

The second service node sends a cognitive transmission resource application to the first service node; the first service node sends a cognitive transmission resource indication to the second service node. The cognitive transmission resource indication is new G link control signaling defined in the StarLight system, and its implementation process can be combined with the description of the corresponding part of the above embodiment. No. After receiving the sensing transmission resource indication, the second service node can determine its subsequent wireless resources for sensing services, and execute subsequent sensing processes accordingly. The first service node as the sensing sender can send the sensing wireless frame to the second service node; the second service node receives the sensing wireless frame and processes it to obtain the sensing result. Since the second service node belongs to the sensing requesting end in this embodiment , you can end this sensing service, such as sending stop sensing signaling to each sensing responder participating in this sensing service. Regarding the process of obtaining the sensing wireless frame and sensing results, reference may be made to the description of the corresponding parts of the embodiment shown in FIG. 2 above, and this embodiment will not be described in detail here.

In some embodiments, when the second service node serves as the sensing requester of this sensing service, the second service node can also serve as the sensing sender and selects the first service corresponding to the sensing range where the second service node is located. The node is a sensing response end and a sensing receiving end. According to the sensing process shown in Figure 5b, the sensing signal sending and receiving operation is implemented, and the obtained sensing result is sent to the second service node.

Among them, the perception service processing method suitable for another perception architecture shown in Figure 5b may include: the second service node sends a perception transmission resource application to the first service node; the first service node sends a perception transmission resource to the second service node Instructions, the implementation process may refer to the description in the corresponding part above, and will not be described again in this embodiment. Afterwards, the second service node may send a cognitive radio frame to the first service node according to the indicated wireless resources, and the first service node receives the cognitive radio frame, obtains a sensing result after processing, and sends the sensing result to the second service node. In this implementation, the process of obtaining the sensing wireless frame and the sensing result can be as described in the corresponding parts of the embodiment shown in Figure 3 above.

In the embodiment of this application, the obtained sensing results can be transmitted through the existing or expanded physical layer transmission channels of the StarLight system, such as the second type of data information transmission in SLB and the data transmission link in SLE. It is also possible to define a new sensing result reporting channel and use control signaling to indicate that the result is sensing result data.

In some embodiments, the sensing transmission resource application sent by the sensing requester of this sensing service can indicate whether other second service nodes located within the sensing range of the first service node respond to the requested sensing service, which is different from the above The sensing service processing method described in the embodiments of Figure 5a and Figure 5b does not require other second service nodes to respond to this sensing service. When other second service nodes are required to assist the second service node belonging to the sensing requester to better complete the sensing service , the sending and receiving functions of the first service node and the second service node in the domain where the second service node is located can be enabled, so that the requested The first service node serves as both a sensing receiving end and a sensing transmitting end of sensing signals, and the other auxiliary second service nodes serve as sensing receiving ends of sensing signals.

As another sensing architecture shown in Figure 5c, this embodiment only enables the signal sending function of the second service node belonging to the sensing requester. That is, the second service node on the right side of Figure 5c serves as the sensing sender. During the sensing service processing process , the second service node uses a unicast mode to send a cognitive transmission resource application to the first service node, and the first service node sends corresponding cognitive transmission resource indications to the second service node and other indicated second service nodes to achieve For the process, please refer to the description of the corresponding part of the above embodiment. It should be understood that the cognitive transmission resource indication can determine the radio resources used by the second service node with different identities for the cognitive service, and the different identities include the cognitive transmitter and the cognitive receiver for the cognitive service.

Afterwards, since the second service node belonging to the perception requester of the perception service also belongs to the perception sender, it can send the cognitive radio frame to the first service node. When the first service node receives the cognitive radio frame sent by the second service node , sending the corresponding cognitive wireless frame to the second service node belonging to the sensing receiver; or when the second service node belonging to the sensing sender sends the cognitive wireless frame to the first service node, the first service node can send the corresponding cognitive wireless frame to the second service node belonging to the sensing receiver. The second service node sends a cognitive radio frame. Among them, the newly defined link control information contained in these two cognitive wireless frames is for the service node type of the sensing sender. One is the newly defined G link (that is, the link for the G node) control information, and the other is The newly defined T link (that is, the link for the T node) control information, information content, and definition implementation method will not be described in detail in this embodiment.

In this way, the first service node receives the sensing result obtained by processing the received sensing wireless frame by the second service node belonging to the sensing receiving end, and uses the received sensing result and the sensing wireless frame sent by the second serving node belonging to the sensing sending end to Processing is performed to obtain the sensing result for the sensing service, and the sensing result is fed back to the second service node belonging to the sensing requester, as shown in the sensing result sending step described on the right side of Figure 5c.

In some embodiments, different from the sensing architecture shown in Figure 5c above, if the second service node belonging to the sensing requester of the sensing service also belongs to the receiving end, that is, only the signal receiving function of the second service node of the sensing requester can be enabled. , enable the signal sending and receiving function of the first service node in the area, and the signal sending function of other auxiliary second service nodes. Referring to another sensing architecture shown in Figure 5d, during the execution of the sensing service processing method, according to the above In the manner described in the article, at the first service node After receiving the sensing transmission resource application, after coordinating the wireless resources for sensing with multiple second service nodes, sending corresponding sensing transmission resource indications to the multiple second service nodes, the first service node sends a request to the third sensing transmission resource belonging to the sensing receiver. When the second service node sends the corresponding cognitive wireless frame, it can receive the cognitive wireless frame sent by the second service node belonging to the sensing sender to process the cognitive wireless frame, obtain the corresponding sensing result, and then send the sensing result to the sensing transmitter. The second service node of the sensing receiving end enables the second service node to process the received sensing wireless frame and the sensing result to obtain the sensing result for the sensing service. However, this sequence of step execution is not limited and may depend on the situation. Depends.

In some embodiments proposed by this application, if the second service node is the sensing requester of this sensing service, the second service node does not have the sensing signal transceiving function, or is not suitable for transmitting and receiving sensing signals to obtain sensing results. , the second service node can expect the first service node in its domain to find other suitable second service nodes to perform sensing signal transceiver operations, obtain and return sensing results. In this scenario, the first service node corresponding to the sensing range of the second service node serving as the sensing requester will be the sensing sender, and the other second service nodes within the sensing range will be the sensing receivers. The configuration is shown in Figure 6a Another sensing architecture. Under this sensing architecture, the first service node and other second service nodes are also sensing responders participating in this sensing service.

During the sensing signaling and signal transmission process as shown in Figure 6a, the first service node can receive the sensing service request signaling sent by the second service node belonging to the sensing requesting end. This signaling is an indication of the high-level sensing service in the StarLight system. , can be sent to the first service node by mapping to air interface control signaling, and the first service node determines the subsequent transmission resources for this sensing service accordingly. That is to say, the second service node sends it in a unicast manner. The cognitive service request signaling may instruct the first service node to determine the radio resources for the requested cognitive service, and the second service node belonging to the perception responder of the cognitive service. This application does not elaborate on how to implement the air interface control signaling obtained through mapping.

Afterwards, the first service node can send a perception transmission resource indication to the second service node belonging to the perception responder. If the perception signal receiving function of the second service node and the sensing signal sending function of the requested first service node are enabled, The first service node can send a sensing wireless frame to the second service node belonging to the sensing responder. The implementation process can refer to the corresponding execution steps of the sensing service processing method shown in Figure 2 above. The second service node processes the sensing signal to obtain the sensing result. After that, you can The sensing result is sent to the first service node through the transmission channel, and then the first service node sends the received sensing result to the second service node belonging to the sensing requester of the corresponding sensing service.

In an application scenario where the second service node applying for a sensing service request needs to send a sensing service request to the first service node, triggering the first service node to send sensing signals to other second service nodes, this application also proposes a method suitable for sensing services Another sensing architecture of the processing method, as shown in Figure 6b, can enable the sensing signal receiving function of the first service node and enable the sensing signal sending function of other second service nodes. In this way, according to the method described above, After the first service node sends a cognitive transmission resource indication to other second service nodes, the second service node can send a cognitive radio frame to the first service node. After receiving the cognitive radio frame, the first service node can follow the predefined instructions. The content is processed to obtain the sensing result of this sensing service, and then the sensing result is sent to the second service node belonging to the sensing requester.

It should be noted that the above-mentioned second service node as the sensing responder can be instructed by the sensing requester when sending the sensing service request signaling, or the first service node can respond to the sensing service in the sensing service management function. The second service node performs selection, and the implementation process may refer to but is not limited to the selection process described in the corresponding part of the above embodiment.

Based on the embodiments of the multi-point sensing architecture described above, a sensing service request for a sensing service can be triggered by an application in the upper service layer, and the service node corresponding to the application is used as the sensing requester. The service node can communicate with the StarLight system. Other service nodes (such as G nodes and/or T nodes) coordinate to complete this sensing service. In the process of realizing the sensing service, different service nodes participating in the sensing service send and receive messages to each other (that is, for a certain The sensing transmitter and sensing receiver of the sensing signal are located at different service nodes) for sensing, and through changes in the wireless propagation environment, the sensing results for the sensing service are obtained.

Among them, the service node as the sensing responder can calibrate the perception of the sensing environment, such as detecting wireless channel information when there is no one in the room, and saving the sensing results to determine whether someone enters the area later. This process can be implemented through enhanced air interface signaling support. Specifically, it can be performed during the establishment process of sensing transmission to achieve air interface enhancement. This application does not limit the implementation method of sensing environment calibration, which can be determined based on the sensing service.

In practical applications, for different sensing services, it is supported to implement sensing service processing methods. The cognitive architecture may be different, including but not limited to the perceptual architectures described above. In some embodiments, the entire sensing service processing process (ie, the sensing process described above) may not require the participation of other service nodes, and the first service node as the sensing requester itself completes a sensing service.

Based on this, refer to Figure 7a, which is another schematic flow chart of the sensing service processing method proposed in this application. This method can be executed by the first service node as the sensing requester, and is suitable for the first service node itself, as shown in Figure 7b A single-point sensing architecture. In this scenario, the first service node itself has the function of sending and receiving sensing signals at the same time, completing sensing service operations in the form of spontaneous and self-receiving, and both signaling and sensing signals are output in a broadcast manner.

Based on this, as shown in Figure 7a, the perception service processing method in this embodiment may include:

Step S71: Send a sensing transmission resource indication for the requested sensing service to the second service node according to the sensing service request;

In the embodiment of this application, the sensing service request is triggered by the first application of the first service node in the service layer. In order to support the sensing service, the sensing time window and guard band are reserved for the sensing service to avoid potential data transmission interference. , the first service node adopts the broadcast mode, and the output sensing transmission resource indication can determine the wireless resources used for the requested sensing service, and also instructs the second service node located within the sensing range of the first service node to transmit information on the corresponding wireless The resource is in a no signal transmission state, so that the second service node does not participate in the transmission operation of the communication signal of the starlight system within the wireless resource, but participates in sensing services within the wireless resource. It can be seen that the embodiments of the present application improve the reliability and accuracy of the sensing results for the sensing service through this processing method of indicating that the sensing responder is in a no-signal-transmitting state within the wireless resource.

It should be noted that the signaling of the cognitive transmission resource indication in this embodiment is different from the definition of the cognitive transmission resource indication sent in the unicast mode in the above embodiments. The cognitive transmission resource indication in this embodiment is in the starlight system. A new system broadcast message is defined. This system message can be used to instruct the second service node in the sensing area to maintain no signal transmission state within the indicated time and frequency band. This can still introduce new types of signals in SLB and SLE respectively. G link control information and physical layer control information are implemented, and the implementation process will not be described in detail in this application.

Step S72: Send the cognitive wireless frame according to the wireless resource, so that the second service node in the no-signal-transmitting state ignores the cognitive wireless frame, and the first service node receives the cognitive wireless frame to process the cognitive wireless frame and obtain the cognitive service. perceived results.

The cognitive wireless frame in this embodiment also includes wireless signals for perception, that is, the above-mentioned perception signals, such as newly defined reference symbols for perception services or reusing existing reference symbols of the Starlight system, etc., in order to obtain the required perception results accordingly. . This control signaling can indicate that the wireless frame is used for sensing signals, and the sensing wireless frame is sent in a broadcast nature. After receiving it, the second service node determines that it is in a no-signal-sending state under the corresponding wireless resource, and can ignore this In the control signaling, the first service node itself receives the broadcasted sensing wireless frame and processes it to obtain the sensing result. Regarding the process of obtaining the sensing results and the control information contained in the sensing wireless frame, reference may be made to the description of the corresponding parts of the above embodiments.

Among them, the first service node of this application, as a star flash node covering a specific area (that is, having a certain sensing range), can sense the sensing service suitable for the target occurrence class within the sensing coverage range, that is, whether a target appears within the range. .

In some embodiments, when any second service node in the Starlight system serves as a sensing requester, it can also enable its own sensing signal transceiver function and complete the sensing service operation by itself. Refer to Figure 8a. In another sensing architecture, in order to ensure the quality of sensing service, the second service node still needs to apply for wireless resources for sensing service from the first service node it serves. Accordingly, the corresponding signaling and process included in Figure 8a are designed. Referring to Figure 8b, which is a schematic flowchart of another optional example of the sensing service processing method proposed in this application. The method can be executed by the second service node. As shown in Figure 8b, the method can include:

Step S81: Send a sensing transmission resource application to the first service node according to the sensing service request;

Step S82: Receive the sensing transmission resource indication for the requested sensing service sent by the first service node;

The cognitive transmission resource indication can determine the radio resources used by the second serving node for cognitive services. Regarding the implementation process of step S81 and step S82, reference may be made to the description of the corresponding parts in the above embodiment in which the second service node serves as the sensing requester.

In some embodiments, the above-mentioned sensing transmission resource indication may also be output in a broadcast manner. In this case, it is used to determine other second service nodes within the sensing range of the first service node as the sensing requester. The wireless resources of this sensing service are in a no-signal-transmitting state, so that any other second service node ignores the received sensing wireless frame, so that the second service node as the sensing requester can obtain better sensing. result. Other articles here The second service node refers to the second service node other than the second service node that sends the sensing transmission resource application within the sensing range of the first service node.

Step S83: Send cognitive radio frames based on the wireless resources, receive cognitive radio frames, process the cognitive radio frames, and obtain sensing results for cognitive services.

Different from the sending method of the cognitive wireless frame in the above embodiment, this embodiment can use the broadcast method to output the cognitive wireless frame. After receiving it, the first service node and the other second service nodes mentioned above can ignore the content through control signaling instructions. Sensing the wireless frame, the second service node itself as the sensing requester receives the sensing wireless frame, and obtains the sensing result after processing. In practical applications, this sensing architecture of a single second service node can be suitable for sensing information about targets near the second service node, such as gesture recognition type sensing services. This application describes the sensing service types used in different sensing architectures. No restrictions.

The steps that the second service node can perform in the perception service processing method under the above multi-point sensing architecture will be described from the side of the second service node. The implementation process can refer to the relevant descriptions of the corresponding sensing architecture embodiments above. , will not be described in detail in the following examples.

Referring to Figure 9, a schematic flow chart of another optional example of the sensing service processing method proposed in this application is executed by the second service node (T node) in the StarLight system. If the second service node serves as this For the sensing response end of the sensing service, combined with the sensing architecture shown in Figure 4b, this method can include:

Step S91: Receive the cognitive transmission resource indication sent by the first service node;

Wherein, the cognitive transmission resource indication can determine the wireless resources used by the second serving node for the cognitive service;

Step S92: Send a cognitive radio frame to the first service node according to the radio resource, so that the first service node processes the cognitive radio frame and obtains a sensing result for the cognitive service.

Optionally, under the architecture shown in Figure 4a, after receiving the cognitive transmission resource indication, the second service node can receive the cognitive wireless frame sent by the first service node based on the wireless resource to process the cognitive wireless frame and obtain the cognitive information for the perception. The sensing result of the service is sent to the first service node.

Under the sensing architecture shown in Figure 4c, multiple second service nodes can participate in sensing. One second service node can send sensing wireless frames as shown in step S92, and another second service node can send sensing wireless frames as shown in step S92. The point can receive the sensing wireless frame and send the obtained sensing result to the first service node. The first service node integrates the sensing signal and the sensing node to obtain the final sensing result for the sensing service.

In some embodiments, refer to Figure 10, which is a flow chart of another optional example of the sensing service processing method proposed in this application. This embodiment is still executed by the second service node, but at this time a certain second service The node serves as the sensing requester of the sensing service. Combined with the sensing architecture shown in Figure 5b, this method can include:

Step S101: Send a cognitive transmission resource application to the first service node according to the cognitive service request;

Step S102: Receive the cognitive transmission resource indication sent by the first service node;

Step S103: Send a cognitive wireless frame to the first service node according to the wireless resource, so that the first service node processes the cognitive wireless frame and obtains a sensing result for the cognitive service;

Step S104: Receive the sensing result fed back by the first service node.

Optionally, under the sensing architecture as shown in Figure 5a, the second service node serving as the sensing requester also serves as the sensing receiving end. Then, after receiving the sensing transmission resource indication, the second service node can receive the sensing transmission resource indication from the first service node. The sent sensing wireless frame is processed to obtain the sensing result, and there is no need to transmit it again.

In some embodiments, referring to the sensing architecture shown in Figure 5c and Figure 5d, in the case where the first service node sends corresponding sensing transmission resource indications to multiple second service nodes, the sensing result fed back by the first service node It can be obtained by the first service node processing the received sensing wireless frame and the sensing result sent by the second service node belonging to the sensing responder of the sensing service. You can refer to the sensing service processing applicable to the sensing architecture shown in Figure 5c above. Description of method embodiments; or, with reference to the above description of the sensing service processing method embodiment applicable to the sensing architecture shown in Figure 5d, the sensing result fed back by the first service node may also be a second sensing response end belonging to the sensing service. The cognitive radio frame sent by the service node is processed and obtained. The implementation process will not be described in detail in this embodiment.

In addition, for the sensing service processing method performed by different second service nodes under the multi-point sensing architecture as shown in Figure 6a and Figure 6b, please refer to the relevant descriptions of the corresponding embodiments above, which will not be described in this application. Detailed examples one by one.

Based on the descriptions in the above embodiments, for different sensing services, single node sensing method/architecture or dual node (G node and T node) sensing can be used according to the corresponding sensing service request content. Method/architecture, multi-node (such as G node, multiple T nodes) collaborative sensing method/architecture suitable one or more sensing architectures, according to the sensing service processing method described in the corresponding method embodiment above, complete this Aware services. For a sensing service under a dual/multi-node sensing architecture, it can be divided into five stages of signaling: sensing service establishment, sensing environment calibration, sensing signal transceiver (i.e. sensing wireless frame transceiver), sensing result reporting, and sensing service end. Interaction, but under the single-node sensing architecture, there is no need to transmit sensing results between nodes. The implementation process of signaling interaction can refer to the description in the corresponding part above, and this embodiment will not be described in detail here.
