Obviously, the embodiments described are only a part of disclosed embodiments of the present disclosure and not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

In the current research on Wi-Fi technology, wireless local area network (WLAN) sensing technology may be supported. For example, application scenarios such as location discovery, proximity detection, and presence detection in dense environments such as home and business environments. In the WLAN sensing procedure, it is necessary to provide a method to indicate the Channel State Information (CSI) threshold, to instruct the sensing receiver (responder) to perform the sensing measurement based on the CSI threshold.

Embodiments of the present disclosure provide a communication method and an apparatus thereof, an electronic device and a storage medium, to provide a method for indicating a CSI threshold in the wireless local area network sensing measurement process.

In some embodiments, the method and the apparatus are based on the same inventive concept. Due to the similar principles of solving problems by the method and by the apparatus, reference can be made between embodiments of the apparatus and the method, and the same will not be repeated.

As shown in FIG. 1, embodiments of the present disclosure provide a communication method, which can be applied to a network device. The network device serves as a sensing initiator, which can be a sensing transmitter or a device that does not participate in the wireless local area network sensing measurement process.

The method can include the following steps.

In step 101, a target radio frame is determined. The target radio frame includes a Channel State Information (CSI) threshold, and the CSI threshold is configured for a responder to send a CSI measurement value to an initiator based on the CSI threshold.

FIG. 2 shows a schematic diagram of a WLAN sensing architecture. The sensing initiator initiates the WLAN sensing (for example, initiating a WLAN sensing session), and there may be multiple sensing responders (or sensing receivers) responding to the WLAN sensing, as is shown by Responder 1, Responder 2, and Responder 3 in FIG. 2. The responder is the receiver that receives a null data packet (NDP) measurement frame sent by a sender. When the sensing initiator initiates the WLAN sensing, multiple sensing responders associated or not associated with the WLAN sensing can respond. As shown in FIG. 2, Responder 1, Responder 2, and Responder 3 can each have an associated or unassociated relationship with the initiator. In some embodiments, “associated” can refer that an association connection for the communication between the sensing initiator and the sensing responder is established, and “unassociated” can refer that the association connection for the communication between the sensing initiator and the sensing responder is not established.

As shown in FIG. 3, the sensing initiator communicates with the sensing responder through a link, as shown by a link S1, and the communication between the sensing responders is carried out through a link S2.

In some embodiments, each sensing initiator can be a client, and each sensing responder (for example, the sensing Responder 1 to the sensing Responder 3) can be a station (STA). The STA can assume multiple roles in the WLAN sensing procedure. For example, in the WLAN sensing procedure, the sensing initiator may be a sensing transmitter, a sensing receiver, or both, or neither. In the WLAN sensing procedure, the sensing responder may also be a sensing transmitter, a sensing receiver, or both.

Another architecture is shown in FIG. 4, the sensing initiator and the sensing responder can be both clients, and the two can be connected to the same AP for communication. In FIG. 4, Client 1 is the sensing initiator and Client 2 is the sensing responder.

In the WLAN sensing procedure, the initiator determines the target radio frame and carries the CSI threshold in the target radio frame. The CSI threshold is the threshold for measuring the CSI variation in the channel. The CSI variation refers to the difference between the currently measured CSI and the previously measured CSI. The CSI threshold is configured for the responder to send the CSI measurement value to the initiator based on the CSI threshold. After receiving the target radio frame, the responder obtains the CSI threshold in the target radio frame and determines, based on the data relationship between the current CSI variation and the CSI threshold, whether to report CSI to the initiator. In some embodiments, if the current CSI variation does not exceed the CSI threshold, the responder may not report CSI, thereby saving signaling messages.

In some embodiments, the target radio frame can be a trigger frame or a message frame in the sensing measurement process. The CSI threshold can come from an upper layer application, for example, the CSI threshold is directly indicated to the initiator by the upper layer.

In step 102, the target radio frame is sent.

The initiator sends the target radio frame to the responder, so that the responder can determine, based on the CSI threshold in the target radio frame, whether to report CSI.

According to embodiments of the present disclosure, the initiator determines the target radio frame and sends the target radio frame to the responder. The target radio frame includes the Channel State Information (CSI) threshold, which is configured for the responder to determine, based on the CSI threshold, whether to send the CSI measurement value to the initiator. Embodiments of the present disclosure provide a method for indicating the CSI threshold in the WLAN sensing procedure.

In some embodiments, the target radio frame includes at least one of a trigger frame, a message frame for sensing session establishment, and a message frame for sensing measurement establishment.

The target radio frame can be the trigger frame, which is mainly configured for scheduling stations and allocating resource units (RU). In some embodiments, in the transmission mechanism based on Orthogonal Frequency Division Multiple Access (OFDMA) technology, the uplink transmission (UL-OFDMA) or the downlink transmission (DL-OFDMA) requires the use of the trigger frame to exchange scheduling information between multi-user communications.

The target radio frame can also be the message frame for sensing session establishment and the message frame for sensing measurement establishment. In some embodiments, the message frame for sensing session establishment is also known as the message frame for WLAN sensing session establishment, which is configured for establishing the sensing measurement session. The message frame for sensing measurement establishment is also known as the message frame for WLAN sensing measurement establishment, which is configured for establishing the sensing measurement process.

In some embodiments, in the uplink sensing measurement, the target radio frame can be the trigger frame, and in the downlink sensing measurement, the target radio frame can be either the message frame for sensing session establishment or the message frame for sensing measurement establishment.

In some embodiments of the present disclosure, the CSI threshold includes a first CSI threshold corresponding to a sensing session, or a second CSI threshold corresponding to a measurement process, or a third CSI threshold corresponding to a measurement instance.

The CSI threshold can be set to be at a sensing session level. That is, each sensing session corresponds to one CSI threshold, which is the first CSI threshold. In some embodiments, each sensing session includes multiple measurement processes. In the same sensing session, for each measurement process, the thresholds used by the responders involved in the measurement process are the same, i.e., the first CSI threshold corresponding to the sensing session.

As shown in FIG. 5, a WLAN sensing procedure is illustrated, where T represents a time axis, AID represents an association identifier, and UID represents a user identifier. FIG. 5 includes multiple sensing session establishment processes, for example, “1. session setup”, “2. session setup”, and “5. session setup”. That “1. session setup” is taken as an example, where the Media Access Control (MAC) of the sensing session (hereinafter referred to as Sensing Session 1) has an address (ADDR) of A, and an AID of 1. The Sensing Session 1 includes two measurement processes, namely Measurement 1 and Measurement 2. In this way, the thresholds used by the responders involved in the processes Measurement 1 and Measurement 2 are the first CSI threshold.

The CSI threshold can also be set as the second CSI threshold corresponding to the measurement process. That is, the CSI threshold is included in the measurement process. In some embodiments, a specific measurement process includes multiple sensing measurement instances, and the CSI thresholds used for each measurement instance are the same, all of which are the second CSI threshold corresponding to this measurement process. All measurement instances under each measurement ID correspond to the same CSI threshold. As shown in FIG. 5, Measurement 1 in Sensing Session 1 includes two measurement instances, namely Measurement instance ID=1 and Measurement instance ID=2. The CSI thresholds corresponding to these two measurement instances are both the second CSI threshold corresponding to the measurement process.

The CSI threshold can also be set as the third CSI threshold corresponding to the measurement instance. That is, the CSI threshold is at a measurement instance level. Each measurement ID contains multiple measurement instances, and each instance corresponds to one CSI threshold. That is, each combination of Measurement ID and Measurement instance ID corresponds to one CSI threshold. As shown in FIG. 5, Measurement 1 in Sensing Session 1 includes two measurement instances, namely Measurement instance ID=1 and Measurement instance ID=2, and these two measurement instances each has one third CSI threshold. Therefore, the CSI thresholds used by the responders involved in each measurement instance are the third CSI threshold corresponding to this measurement instance.

In some embodiments, in case that the CSI threshold includes the first CSI threshold, the target radio frame includes the message frame for sensing session establishment, i.e., the message frame for WLAN sensing session establishment (sensing session setup). The message frame for WLAN sensing session establishment carries the first CSI threshold indicating the CSI thresholds used by responders involved in each measurement process under this sensing session.

In some embodiments, in case that the CSI threshold includes the second CSI threshold, the target radio frame includes the message frame for sensing session establishment.

In the message frame for sensing session establishment, the second CSI threshold corresponds to a measurement process identifier. In some embodiments, the message frame for sensing session establishment can include multiple measurement processes, and each measurement process has one second CSI threshold.

In some embodiments, in case that the CSI threshold includes the third CSI threshold, the target radio frame includes the message frame for sensing measurement establishment (measurement setup).

In the message frame for sensing measurement establishment, the third CSI threshold corresponds to the identifier combination of the measurement process identifier and the measurement instance identifier. That is, the CSI threshold is at a measurement instance level. Each measurement ID contains multiple measurement instances, and each measurement instance corresponds to one CSI threshold. In the message frame for sensing measurement establishment, each combination of Measurement ID and Measurement instance ID corresponds to one CSI threshold.

In some embodiments, after the target radio frame is sent, the method further includes following steps.

A CSI measurement value sent by the responder is received. The CSI measurement value is sent by the responder to the initiator, in response to the measured CSI variation exceeding the CSI threshold. The responder determines, based on the CSI threshold in the target radio frame and the CSI variation, whether to report CSI. If the CSI variation does not exceed the CSI threshold, CSI will not be reported, thereby saving signaling messages.

As shown in FIG. 6, embodiments of the present disclosure also provide a communication method, which can be applied to a responder (i.e., the sensing responder). The method can include the following steps.

In step 601, a target radio frame is received and a Channel State Information (CSI) threshold carried in the target radio frame is obtained.

FIG. 2 shows a schematic diagram of a WLAN sensing architecture. The sensing initiator initiates the WLAN sensing (for example, initiating a WLAN sensing session), and there may be multiple sensing responders (or sensing receivers) responding to the WLAN sensing, as is shown by Responder 1, Responder 2, and Responder 3 in FIG. 2. When the sensing initiator initiates the WLAN sensing, multiple sensing responders associated or not associated with the WLAN sensing can respond. As shown in FIG. 2, Responder 1, Responder 2, and Responder 3 can each have an associated or unassociated relationship with the initiator. In some embodiments, “associated” can refer that an association connection for the communication between the sensing initiator and the sensing responder is established, and “unassociated” can refer that the association connection for the communication between the sensing initiator and the sensing responder is not established.

In the WLAN sensing procedure, the responder receives the target radio frame and obtains the CSI threshold carried in the target radio frame. The CSI threshold is the threshold for measuring the CSI variation in the channel. The CSI variation refers to the difference between the currently measured CSI and the previously measured CSI. The CSI threshold is configured for the responder to send the CSI measurement value to the initiator based on the CSI threshold. After receiving the target radio frame, the responder obtains the CSI threshold in the target radio frame.

In step 602, a processing operation is performed based on a CSI variation and the CSI threshold.

After obtaining the CSI threshold, the responder determines, based on the data relationship between the current CSI variation and the CSI threshold, whether to report the CSI measurement value to the initiator. In some embodiments, if the current CSI variation does not exceed the CSI threshold, the responder may not report CSI, thereby saving signaling messages. In response to the measured CSI variation exceeding the CSI threshold, the responder sends the CSI measurement value to the initiator.

In some embodiments, the target radio frame includes at least one of a trigger frame, a message frame for sensing session establishment, and a message frame for sensing measurement establishment.

In some embodiments, in case that the CSI threshold includes the first CSI threshold, the target radio frame includes the message frame for sensing session establishment.

In some embodiments, in case that the CSI threshold includes the second CSI threshold, the target radio frame includes the message frame for sensing session establishment.

In the message frame for sensing session establishment, the second CSI threshold corresponds to a measurement process identifier.

In some embodiments, in case that the CSI threshold includes the third CSI threshold, the target radio frame includes the message frame for sensing measurement establishment.

In the message frame for sensing measurement establishment, the third CSI threshold corresponds to the combination of the measurement process identifier and the measurement instance identifier.

In some embodiments, performing the processing operation based on the CSI variation and the CSI threshold includes following steps:

- a null data packet (NDP) sent by the initiator is received, the CSI is measured, and the CSI variation is determined;
- the CSI measurement value is sent to the initiator in response to the CSI variation exceeding the CSI threshold; and
- the NDP sent again by the initiator is not processed, in response to the CSI variation not exceeding the CSI threshold. That is, the subsequent NDP sent by the initiator is ignored, and the CSI measurement value is not reported to the initiator, thereby saving signaling messages.

According to embodiments of the present disclosure, the responder receives the target radio frame, which includes the Channel State Information (CSI) threshold. The CSI threshold is configured for the responder to determine, based on the CSI threshold, whether to send the CSI measurement value to the initiator.
