Description

[Technical Field]

[0001] This application relates to the field of communications, and in particular to monostatic sensing methods and related products. [Background technology]

[0002] Wireless local area network (WLAN) sensing is a technology with wide application potential. WLAN sensing senses the surrounding environment by using radio frequency (RF) signals transmitted by WLAN devices and extracts corresponding parameters in the received signals for analysis according to a specific algorithm to obtain relevant information about the surrounding environment.

[0075] To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the system architecture and / or application scenarios of the monostatic sensing method provided in the embodiments of the present application. The scenarios described in the embodiments of the present application are intended to more clearly describe the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application.

[0076] An embodiment of the present application provides a monostatic sensing method that can be applied to a wireless communication system. The wireless communication system may be a wireless local area network or a cellular network. The method can be implemented by a communication device in the wireless communication system, or a chip or processor in the communication device. The communication device may be a Personal Basic Service Set Control Point (PBSS Control Point, PCP), an access point (AP) device, or a station (STA) device.

[0077] 1 is a diagram of a system architecture according to an embodiment of the present application. As shown in FIG. 1, the system architecture includes at least two WLAN devices (e.g., one AP and three STAs are included in FIG. 1). One WLAN device (e.g., STA) performs monostatic sensing, and the other WLAN device (e.g., AP) requests sensing results from the WLAN device performing monostatic sensing. The WLAN devices may support a WLAN communication protocol.

[0078] In this application, the device implementing the method of this application may be a PCP / AP or STA in a WLAN, or a chip or processing system installed in the PCP / AP or STA.

[0079] A PCP / AP is a device with wireless communication capabilities, supports communication according to a WLAN protocol, and has the capability to communicate with other devices (e.g., stations or other access points) within a WLAN device. A PCP / AP may further have the capability to communicate with other devices. In a WLAN system, an access point is sometimes referred to as an access point station (AP STA). A device with wireless communication capabilities may be an entire device, or a chip, processing system, etc. installed in the entire device. A device with a chip or processing system installed may implement the methods and functions of the embodiments of the present application under the control of the chip or processing system. A PCP / AP in the embodiments of the present application is a device that provides services for STAs and supports 802.11 series protocols. For example, an AP may be a communication entity such as a communication server, router, switch, or network bridge. A PCP / AP may include various forms of macro base stations, micro base stations, relay stations, etc. Alternatively, a PCP / AP may be various forms of chips and processing systems within these devices to implement the methods and functions of the embodiments of the present application.

[0080] A station (STA) is a device with wireless communication capabilities, supports communication according to a WLAN protocol, and communicates with other stations or access points within a WLAN network. In a WLAN system, a station may be called a non-access point station (non-AP STA). For example, a STA is any user communication device that enables a user to communicate with a PCP / AP to communicate with a WLAN. The device may be an entire device, or a chip, processing system, etc. installed in the entire device. A device with a chip or processing system installed may implement the methods and functions of embodiments of the present application under the control of the chip or processing system. For example, a STA may be a user device capable of connecting to the Internet, such as a tablet computer, desktop computer, laptop computer, notebook computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), or mobile phone. Alternatively, the STA may be an Internet of Things node in the Internet of Things, an in-vehicle communication device in the Internet of Vehicles, an inter-tainment device, a gaming console or system, a global positioning system device, etc. Alternatively, the STA may be a chip or processing system within the above terminals.

[0081] The following first describes the terms and technical features in the embodiments of the present application.

[0082] 1.802.11fb IEEE 802.11bf is a next-generation wireless standard that focuses on sensing passive objects (i.e., targets do not carry any devices). According to 802.11bf, corresponding parameters of a target (e.g., speed, distance, and angle) are estimated based on a received signal, and subsequent actions / movements are recognized. 802.11bf includes two main standard types: one is a standard for low frequencies (below 7 GHz, standard implementations are mainly based on 11ac, 11ax, 11be, next-generation standards, etc.), and the other is a standard for high frequencies (60 GHz, standard implementations are mainly based on 11ad, 11ay, next-generation standards, etc.). The technical solution of the present application can be applied to high frequencies (11ad / DMG and 11ay / EDMG) or low frequencies (standards corresponding to below 7 GHz).

[0083] Because high-frequency electromagnetic waves have greater attenuation, directional beams are usually used for transmission and reception in existing high-frequency standards DMG / EDMG. This is a major difference between high-frequency standards and low-frequency standards below 7 GHz. However, compared to low frequencies, high frequencies have larger bandwidths, higher carrier frequencies, and better sensing performance. Due to directional transmission, some angle information may be provided, and interference can be reduced to a certain extent, which helps improve sensing performance.

[0084] In the higher frequencies of 802.11bf (11ad, 11ay), monostatic, bistatic, and multistatic sensing modes are supported.

[0085] Monostatic mode is a sensing mode in which the same device is used for transmission and reception. In this mode, both transmission and reception are performed by the same device. Therefore, better (time and frequency) synchronization can be achieved, and the sensing performance is excellent.

[0086] Bistatic mode is a sensing mode in which transmission and reception are separated, and is sometimes called passive sensing. That is, transmission and reception are performed by two devices operating independently. In this mode, transmission and reception are not performed by the same device, and sensing performance may be affected (by asynchronization).

[0087] Multistatic mode is a sensing mode that includes one transmitter / multiple transmitters and multiple receivers, or multiple transmitters and one receiver / multiple receivers. In this mode, multiple devices work together. That is, this mode is a hybrid operation mode that includes multiple monostatic / bistatic modes.

[0088] 2. 802.11ad / ay beacon interval (BI) In 802.11ad / ay, the time axis is divided into BIs. Figure 2 is a diagram of the structure of a beacon interval BI. As shown in Figure 2, the beacon interval is divided into a beacon header indication (BHI) and a data transmission interval (DTI). The BHI further includes a beacon transmission interval (BTI), an association beamforming training (A-BFT) interval, and an announcement transmission interval (ATI).

[0089] Specifically, the PCP / AP transmits multiple beacon frames in the BTI based on the sector number. The beacon frames are used for downlink sector sweep. A-BFT is used for association and uplink sector sweep. The ATI is used by the PCP / AP to poll buffered data information from STAs and allocate resources within a data transmission interval (DTI) to STAs. The entire DTI is divided into several subintervals, and the subintervals are divided into a contention-based access period (CBAP) and a service period (SP) based on the access scheme. Within the service period, transmission scheduling is performed without contention.

[0090] 3.DMG Beacon-Based Passive Sensing The AP initially carries a sensing short capability element in the beacon, which indicates that the AP supports passive sensing. If a STA in the environment should use the beacon information transmitted by the AP for sensing, the STA may send an information request frame to the AP to request the AP to send information about the beacon. The AP uses an information response frame to send the beacon's transmission information (e.g., transmission time and transmission beam direction) to the STA. The STA may use the information to receive the beacon transmitted by the AP and perform passive sensing based on the beacon's transmission information.

[0091] 4. SSW frame and short SSW frame Beam training in 802.11ad is primarily performed during the Association Beamforming Training (A-BFT). First, in the BTI phase, the PCP / AP transmits a beacon frame in each direction. The A-BFT length field in the frame indicates the total slot length of the A-BFT phase. The STA that receives the frame randomly selects a slot from [0, A-BFT length - 1] in the next A-BFT phase for access and then transmits an SSW frame sequentially using a directional antenna (i.e., RXSS). In this case, the PCP / AP uses a quasi-omnidirectional antenna to receive beams from all directions and records the STA's optimal transmission beam. Then, in the sector sweep feedback (SSW feedback) phase, the PCP / AP feeds back the training information from the previous phase (RSS) to the STA using a directional beam. The feedback information is the initiator transmission sector list obtained by sorting by sector quality, including the responder's optimal sector from the previous phase. In this case, the responder is in quasi-omnidirectional receive mode. The sector sweep acknowledgment (SSW ACK) phase is the final phase. The SSW ACK phase may not be present if SLS is performed before the data transmission phase (DTI), and the SSW ACK phase is required if SLS is performed in the DTI phase. In the SSW ACK phase, the STA feeds back the responder transmitting sector list obtained by sorting by quality.

[0092] Furthermore, to meet the access training requirements of more users, an EDGM STA type is added to 802.11ay. The difference between the EDGM STA type in 802.11ay and the traditional DGM STA in 802.11ad is that the EDGM STA can transmit both SSW frames and short SSW frames in the A-BFT slots scheduled in the A-BFT phase. Compared with the SSW frame, the short SSW frame has a shorter frame length, so the EDGM STA can transmit more data in one slot.

[0093] 3 is a flowchart diagram of a monostatic sensing method according to an embodiment of the present application. The monostatic sensing method can be applied to the communication system shown in FIG. 1. The first device can be the PCP / AP shown in FIG. 1, or the first device can be the STA shown in FIG. 1. 3 As shown in Figure 1, the method includes the following steps:

[0094] 101: A first device performs monostatic sensing based on a first frame structure to obtain a first sensing result.

[0095] 102: The second device sends a first request frame to the first device, where the first request frame is used to request to obtain a monostatic sensing result, and the first device receives the first request frame accordingly.

[0096] 103: The first device sends a first response frame to the second device based on the first request frame, where the first response frame includes the first sensing result. In response, the second device receives the first response frame.

[0097] The first device may be a PCP / AP or a STA. If the first device is a PCP / AP, the first frame structure includes one of the following: a DMG beacon frame, a data frame, or a BRP. If the first device is a STA, the first frame structure is one of the following: a sector sweep SSW, a short SSW, a BRP, or a data frame. A training field (TRN) may be carried at the end of the first frame structure, and sensing is facilitated because the TRN is used for sweeping.

[0098] For example, if the PCP / AP has a monostatic sensing function, the PCP / AP may perform monostatic sensing based on a DMG beacon frame, a data frame, or a BRP to obtain a first sensing result. If the STA has a monostatic sensing function, the STA may perform monostatic sensing based on an SSW, a short SSW, a data frame, or a BRP to obtain a first sensing result.

[0099] In a possible design, the first device may perform monostatic sensing based on a first frame structure transmitted by the first device to obtain a first sensing result, and transmit the first sensing result to the second device. Specifically, optionally, the second device may request to obtain the monostatic sensing result from the first device by using a first request frame, and the first device may transmit the first sensing result to the second device by using a first response frame. Optionally, the first request frame may be a DMG sensing poll frame or an information request frame. Furthermore, the second device may perform passive sensing based on the first frame structure transmitted by the first device. The second device may request, from the first device, target beam information for transmitting the first frame structure by the first device and information about the target position of the first device transmitting the first frame structure. The target beam information may include a horizontal beam direction, a vertical beam direction, and a horizontal beam direction. beamThe target position information includes, but is not limited to, information regarding the orientation of the first device transmitting the first frame structure. Note that the position information may be position coordinates determined by using the first device as the origin of coordinates or by using other coordinates as the origin of coordinates. Correspondingly, the first device sends the target beam information and the target position information to the second device. The second device not only performs passive sensing based on the first frame structure, the target beam information, and the target position information, but also parses or interprets the acquired first sensing results by using the target beam information and the target position information to perform passive sensing and monostatic sensing based on the same procedure. In this way, sensing efficiency is improved and repeated transmission of the beam information and the position information is avoided. Furthermore, the second device may further perform comprehensive sensing based on the monostatic sensing results and passive sensing results transmitted by the first device. In this way, the diversity gain of simultaneous sensing is increased and the sensing performance is improved.

[0100] In another possible design, the first device may announce that monostatic sensing is to be performed based on a first frame structure, and the second device may request the first sensing result of the monostatic sensing from the first device by using a first request frame. Optionally, the first request frame may be a DMG Sensing Poll frame. Specifically, optionally, if the first device is a PCP or AP, the first frame structure may be a DMG Beacon frame in the current or next BTI. That is, the PCP or AP announces that monostatic sensing is being performed based on a DMG Beacon frame in the current BTI or that monostatic sensing is to be performed based on a DMG Beacon frame in the next BTI. After the current or next BTI ends, the STA may request the first sensing result of the performed monostatic sensing from the PCP or AP. Alternatively, the first frame structure may be a Data frame in the current or next BTI. That is, the PCP or AP announces that monostatic sensing is being performed based on a data frame in the current DTI, or that monostatic sensing should be performed based on a data frame in the next DTI. After the current or next DTI is completed, the STA may request the PCP or AP for the first sensing result of the performed monostatic sensing. The first frame structure may alternatively be a BRP in the current or next DTI. That is, the PCP or AP announces that monostatic sensing is being performed based on a BRP in the current DTI, or that monostatic sensing should be performed based on a BRP in the next DTI. After the current or next DTI is completed, the STA may request the PCP or AP for the first sensing result of the performed monostatic sensing.

[0101] If the first device is a STA, the first frame structure may be an SSW or short SSW in the current or next A-BFT. That is, the STA announces that monostatic sensing is being performed based on an SSW or short SSW in the current A-BFT, or that monostatic sensing should be performed based on an SSW or short SSW in the next A-BFT. After the current or next A-BFT is completed, the PCP or AP may request the STA for the first sensing result of the performed monostatic sensing. Alternatively, the first frame structure may be a data frame in the current or next DTI. That is, the STA announces that monostatic sensing is being performed based on a data frame in the current DTI, or that monostatic sensing should be performed based on a data frame in the next DTI. After the current or next DTI is completed, the PCP or AP may request the STA for the first sensing result of the performed monostatic sensing. STA The first frame structure may alternatively be a BRP in the current or next DTI. That is, the STA announces that monostatic sensing is being performed based on the BRP in the current DTI, or that monostatic sensing should be performed based on the BRP in the next DTI. After the current or next DTI is completed, the PCP or AP may request the STA for the first sensing result of the performed monostatic sensing.

[0102] It should be noted that, in order to interpret the first sensing result, the second device may further request from the first device target beam information for transmitting the first frame structure and information regarding the target position of the first device transmitting the first frame structure.

[0103] In this possible implementation, the second device may or may not perform passive sensing, i.e., the monostatic sensing is not bound to passive sensing, thus increasing the flexibility of the monostatic sensing method.

[0104] Figure 4 is a flowchart diagram of another monostatic sensing method according to an embodiment of the present application. The method procedure of Figure 4 is a possible implementation of the method of Figure 3. As shown in Figure 4, the method includes the following steps:

[0105] 201: The first device announces that the first device has a monostatic sensing function by using the third information, and announces that the first device has a passive sensing function by using the fourth information.

[0106] In some implementations, the first device transmits the third information and the fourth information, where the third information is used to announce that the first device has a monostatic sensing capability, or the third information indicates that the first device supports monostatic sensing. The fourth information is used to announce that the first device has a passive sensing capability, or the fourth information indicates that the first device supports passive sensing, and other devices may request the first device to transmit beam information and location information. The first device may transmit the third information and the fourth information by broadcasting, multicasting, or unicasting. The second device receives the third information and the fourth information accordingly.

[0107] The third information and the fourth information may be included in the second frame structure. Optionally, the third information and the fourth information may be included in a function element field of the second frame structure, for example, a DMG short sensing function element field.

[0108] In a first optional implementation, the first device is a PCP / AP, and the PCP / AP performs monostatic sensing based on a beacon frame or a BRP, that is, the first frame structure is a DMG beacon frame or a BRP.

[0109] In a DMG short sensing capability element field of the second frame structure, the PCP / AP may announce that the PCP / AP has monostatic sensing capability. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a probe request frame, a probe response frame, etc.

[0110] The structure of the DMG sensing short capability element field may have the structure shown in Figure 5a. The third information and fourth information may be included in the short sensing capability field within the DMG sensing short capability element field. Figures 5b and 5c are diagrams of the structure of two optional short sensing capability fields. Within the structure, the monostatic sensing support subfield carries the third information, in other words, the third information is included in the monostatic sensing support subfield. The passive sensing support subfield carries the fourth information, in other words, the fourth information is included in the passive sensing support subfield.

[0111] In this embodiment of the present application, a monostatic sensing support subfield is added to the short sensing capabilities field to determine whether the AP supports monostatic sensing. If passive sensing support is 1 and monostatic sensing support is 1, the bit combination indicates that the AP supports beacon passive sensing and can provide beacon-based monostatic sensing results. It can be understood that after the monostatic sensing support subfield is added, the sensing support field in the short sensing capabilities field indicates that some other sensing mode besides passive sensing and monostatic sensing is supported.

[0112] In a second optional implementation, the first device is a PCP / AP, and the PCP / AP performs monostatic sensing based on a data frame, that is, the first frame structure is a data frame.

[0113] In a possible implementation, the PCP / AP may announce in the DMG short sensing capability element field of the second frame structure that the PCP / AP has monostatic sensing capability. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a data frame, a probe request frame, a probe response frame, etc. Specifically, optionally, the third and fourth information may be included in the short sensing capability field in the DMG short sensing capability element. For details, see the first optional implementation.

[0114] In another possible implementation, at least one bit may be further used in the assignment field corresponding to the extended schedule element of the DMG beacon frame to indicate that the assignment is used for / supports passive sensing and monostatic sensing. That is, the second frame structure is a DMG beacon frame. Figures 5d and 5e are diagrams of two structures of the assignment field. As shown, reserved bits in the assignment control subfield may be used to carry the third and fourth information. The PCP / AP may also announce that it supports passive sensing by using the DMG short sensing capability element and indicate that the assignment supports monostatic sensing by using a bit in the assignment field corresponding to the extended schedule element of the beacon.

[0115] In a possible implementation, at least one bit may alternatively be added to the data frame to indicate that the PCP / AP supports passive sensing and monostatic sensing, or to indicate that the PCP / AP has passive sensing and monostatic sensing capabilities. That is, the second frame structure is a data frame. For example, at least one reserved bit in either the PHY header or the MAC header may be used to carry the third and fourth information. The PCP / AP may also announce that it supports passive sensing by using the DMG short sensing capability element and indicate that it supports monostatic sensing by using one bit added to the data frame.

[0116] In a third optional implementation, the first device is a STA, and the STA performs monostatic sensing based on an SSW, a short SSW, or a BRP. In other words, the first frame structure is an SSW, a short SSW, or a BRP.

[0117] In the DMG short sensing capability element field of the second frame structure, the STA may announce that the STA has monostatic sensing capability or that the STA supports monostatic sensing. Optionally, the second frame structure may be an Association Request Frame, an Association Response Frame, a Reassociation Request Frame, a Reassociation Response Frame, an Information Request Frame, an Information Response Frame, an SSW frame, a short SSW frame, a Probe Request frame, a Probe Response frame, etc.

[0118] The structure of the DMG sensing short capability element field may have the structure shown in FIG. 5a. The third information and fourth information may be included in the short sensing capability field within the DMG sensing short capability element field. FIGS. 5b and 5c are diagrams of the structure of two optional short sensing capability fields. Within the structure, the monostatic sensing support subfield carries the third information, i.e., the third information is included in the monostatic sensing support subfield. The passive sensing support subfield carries the fourth information, i.e., the fourth information is included in the passive sensing support subfield. For details, please refer to the specific description of the first optional implementation. Details will not be described again here. Note that if the device is a STA, passive sensing support is 1, and monostatic sensing support is 1, the bit combination indicates that the STA supports passive sensing and can provide monostatic sensing results.

[0119] Optionally, the STA may transmit an SSW or a short SSW in the A-BFT process and may use a reserved bit in the SSW or short SSW to indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability. Figure 5f is a diagram of the structure of an SSW according to the present application. The reserved bit in the SSW feedback field of the SSW may indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability. Figure 5g is a diagram of the structure of a short SSW according to the present application. The reserved bit in the short SSW may indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability. In other words, the reserved bit in the SSW or short SSW is used to carry or represent third information.

[0120] In a fourth optional implementation, the first device is a STA, and the STA performs monostatic sensing based on a data frame, that is, the first frame structure is a data frame.

[0121] In a possible implementation, the STA may announce that it has monostatic sensing capability in a DMG short sensing capability element field of the second frame structure. Optionally, the second frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, an information response frame, an SSW frame, a short SSW frame, a probe request frame, a probe response frame, a data frame, etc. Specifically, optionally, the third and fourth information may be included in a short sensing capability field in the DMG short sensing capability element. For details, please refer to the first optional implementation. Note that if the device is a STA, passive sensing support is 1, and monostatic sensing support is 1, the bit combination indicates that the STA supports passive sensing and can provide monostatic sensing results.

[0122] Optionally, the STA may transmit an SSW or a short SSW in the A-BFT process and may use a reserved bit in the SSW or short SSW to indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability. Figure 5f is a diagram of the structure of an SSW according to the present application. The reserved bit in the SSW feedback field of the SSW may indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability. Figure 5g is a diagram of the structure of a short SSW according to the present application. The reserved bit in the short SSW may indicate that the STA supports monostatic sensing or that the STA has monostatic sensing capability.

[0123] In a possible implementation, at least one bit may be added to the data frame to indicate that the STA supports passive sensing and monostatic sensing, or to indicate that the STA has passive sensing and monostatic sensing capabilities. That is, the second frame structure is a data frame. For example, at least one reserved bit in either the PHY header or the MAC header may be used to carry the third and fourth information. The STA may also announce that it supports passive sensing by using the DMG short sensing capability element, and indicate that it supports monostatic sensing by using one bit added to the data frame.

[0124] 202: The second device transmits first information and second information to the first device, where the first information is used to request the first device to perform monostatic sensing, and the second information is used to request the first device to acquire target beam information and target position information, where the target beam information is beam information for transmitting the first frame structure by the first device, and the target position information is information regarding the position of the first device transmitting the first frame structure. Correspondingly, the first device receives the first information and the second information.

[0125] 203: The first device performs monostatic sensing based on the first information and the first frame structure to obtain a first sensing result.

[0126] 204: The second device sends a first request frame to the first device, where the first request frame is used to request to obtain a monostatic sensing result, and the first device receives the first request frame accordingly.

[0127] 205: The first device sends a first response frame to the second device, where the first response frame includes the first sensing result. In response, the second device receives the first response frame.

[0128] 206: The first device transmits target beam information and target position information based on the second information.

[0129] 207: The second device performs passive sensing based on the first frame structure, the target beam information, and the target position information.

[0130] 208: The second device parses the first sensing result based on the target beam information and the target position information.

[0131] In some embodiments, the second device parses relevant information in the second frame structure, such as the third information and the fourth information. The second device may use the third information to determine that the first device supports monostatic sensing. The second device may use the first information to request the first device to perform monostatic sensing. The second device may use the fourth information to determine that the first device supports passive sensing, and the second device may use the second information to request target beam information and target location information from the first device. To help the second device parse the monostatic sensing results of the first device, the second device also needs to request target beam information and target location information from the first device.

[0132] For example, the first information and the second information may be included in an information request frame. For example, the first information and the second information may be included separately in different elements of the information request frame, or the first information and the second information may be included in a passive sensing information element of the information request frame (e.g., a DMG passive sensing beacon information element / DMG passive sensing SSW information element / DMG short sensing capability passive sensing short SSW information element / DMG passive sensing information element), or the first information and the second information may be included separately in different request frames. For example, the second information may be included in an information request frame, and the first information may be included in another request frame (e.g., a DMG sensing measurement setup request / DMG sensing measurement instance element / DMG sensing request). This is not a limitation of the present application.

[0133] Specifically, optionally, the second device may receive target position information of the first device (including information about the orientation for transmitting the first frame structure) and target beam information (horizontal beam direction, vertical beam direction, etc.) for transmitting the first frame structure by the first device. beamThe second device may transmit an information request frame to the first device to request information about the first device's target position (including the direction, horizontal beam width, vertical beam width, and beam gain), and then perform passive sensing based on the first frame structure transmitted by the first device. In addition, when the first device subsequently transmits the first frame structure, the second device may request the first device to perform monostatic sensing based on the first frame structure. After the sensing is completed, the second device may request the first device for the first sensing result of the monostatic sensing based on the first frame structure. It may be understood that the target position information of the first device and the target beam information for transmitting the first frame structure requested by the second device may also be used to interpret or parse the first sensing result.

[0134] For example, the first device is an AP or a PCP, the second device is a STA, and the first frame structure is a beacon. The STA may request the AP to transmit information such as target beam information for the beacon and target location information of the AP by using a DMG passive sensing beacon information element included in the information request frame. The AP transmits an information response frame to the STA, which includes a DMG passive sensing beacon information element (which describes the beacon transmission time, the AP's location, and other information) and one or more DMG beacon sector descriptor elements (which describe the beam information for the beacon transmission, etc.).

[0135] In an embodiment of the present application, the first information used to request the AP to perform monostatic sensing may be included in a DMG passive sensing beacon information element of an information request frame. In other words, the DMG passive sensing beacon information element further includes instruction information (i.e., the first information) for requesting the AP to perform monostatic sensing based on the beacon. FIG. 5h is a diagram of the structure of a DMG passive sensing beacon information element. The first information of the present application may be included in the beacon information control field, or may be included in another field of the DMG passive sensing beacon information element. For example, FIG. 5i is a diagram of a possible structure of the beacon information control field. A monostatic sensing request bit is added to the beacon information control field to request the AP to perform monostatic sensing. That is, the monostatic sensing request includes the first information, and the first information is carried in the monostatic sensing request bit. For example, FIG. 5j is a diagram of another possible structure of the beacon information control field. Compared with that of Figure 5i, the beacon information control field of Figure 5j includes a "Next Beacon" field, which indicates that the target beam information subsequently transmitted by the AP is used to describe a beacon in the current BTI or a beacon in the next BTI. It can be understood that the monostatic sensing request bit of Figure 5j is also used to request the AP to perform monostatic sensing. Specifically, the monostatic sensing request bit includes first information, and the first information is carried in the monostatic sensing request bit.

[0136] The STA uses an information request frame to request the AP's target location information and related information of the target beam that transmits the beacon, and in the information request frame requests the AP to perform monostatic sensing based on the beacon.

[0137] In this case, based on the target location information and the relevant information of the target beam transmitting the beacon transmitted by the AP, the STA performs passive sensing by using the beacon transmitted by the AP, and the AP performs monostatic sensing based on the beacon upon the request of the STA. Then, the STA may request the beacon-based monostatic sensing result, i.e., the first sensing result, from the AP. The AP feeds back the first sensing result by using a first response frame. After receiving the first sensing result, the STA performs analysis in combination with the passive sensing result.

[0138] Optionally, the monostatic sensing request bit used to carry the first information may alternatively be included in a new element, in which case the information request frame includes two elements: one element requests information about passive sensing (i.e., a DMG passive sensing beacon information element), and the other element requests monostatic sensing.

[0139] It should be noted that requesting target beam information and target location information and requesting the AP to perform monostatic sensing may be implemented separately by using two frames. Specifically, the information request / response is used to exchange transmission beam information for the beacon and target location information of the AP, and the STA requests the AP to perform monostatic sensing based on the beacon by using another request frame (e.g., DMG Transmission Measurement Setup Request / DMG Transmission Measurement Instance Request / DMG Transmission Request). Correspondingly, the AP feeds back the monostatic sensing result based on the response frame corresponding to the other request frame. It may be understood that if the first frame structure is a BRP, the beacon in the above interaction procedure may be replaced with a BRP.

[0140] Similarly, the monostatic sensing device is an STA, that is, the first device is an STA, and the second device is an AP or a PCP. Corresponding procedures can be used to complete the interaction of related information request and feedback. It can be understood that if the monostatic sensing device is an STA, the information request / response frame includes a corresponding DMG passive sensing (SSW / short SSW / BRP) information element. Correspondingly, the information in the element is mainly used to describe information about the SSW / short SSW / BRP sent by the STA in the A-BFT. A monostatic sensing request bit can be added to the DMG passive sensing (SSW / short SSW / BRP) to request the STA to perform monostatic sensing. The bit can be located in the (SSW / short SSW / BRP) information control field. Alternatively, the information request frame may include a DMG passive sensing (SSW / short SSW / BRP) information element and other elements, and the other elements include a monostatic sensing request bit and are used to request the STA to perform monostatic sensing. Alternatively, the information request frame may be used to request the STA to send target beam information of the SSW / short SSW / BRP and target location information of the STA, and the AP requests the STA to perform monostatic sensing based on (SSW / short SSW / BRP) by using other request frames (e.g., DMG sensing measurement setup request / DMG sensing measurement instance element / DMG sensing request).

[0141] It can be understood that when the PCP / AP or STA performs monostatic sensing and passive sensing based on the data frame, the information request / response frame includes a corresponding DMG passive sensing (data PPDU) information element. Correspondingly, the information in the element is mainly used to describe the relevant information of the data frame data PPDU sent by the PCP / AP or STA. For specific interaction procedures, please refer to the description of the above embodiment. The details will not be described again here.

[0142] The target beam information of the first frame structure transmitted by the first device and the target position information of the first device transmitting the first frame structure can be used to simultaneously interpret the results of both passive sensing and monostatic sensing. This improves sensing efficiency and reduces the overhead of exchanging position information and beam sensing information. Simultaneous passive sensing and monostatic sensing based on the same beacon / SSW / short SSW / data frame are also performed. In this way, sensing diversity gain at the same time is increased. Sensing performance can be improved compared to the performance of independent sensing.

[0143] 6 is a flowchart diagram of yet another monostatic sensing method according to an embodiment of the present application. The method procedure of FIG. 6 is a possible implementation of the method of FIG. 3. As shown in FIG. 6, the method includes the following steps:

[0144] 301: The first device announces that the first device performs monostatic sensing based on the first frame structure by using the fifth information.

[0145] 302: The first device performs monostatic sensing based on the first frame structure to obtain a first sensing result.

[0146] 303: The second device sends a first request frame to the first device, where the first request frame is used to request to obtain a monostatic sensing result.

[0147] 304: The first device sends a first response frame to the second device, where the first response frame includes the first sensing result.

[0148] Optionally, the method may further include step 305 .

[0149] 305: The second device sends a second request frame to the first device, where the second request frame is used to request to obtain target beam information and target position information.

[0150] 306: The first device transmits target beam information and target location information to the second device, where the target beam information is beam information for transmitting the first frame structure by the first device, and the target location information is information regarding the location of the first device transmitting the first frame structure.

[0151] 307: The second device parses the first sensing result based on the target beam information and the target position information.

[0152] In some implementations, the first device transmits the fifth information, which is used to announce that the first device should perform monostatic sensing based on the first frame structure, or the fifth information is used to announce that the first device is performing monostatic sensing based on the first frame structure. The first device may transmit the fifth information by broadcasting, multicasting, or unicasting. The second device receives the fifth information accordingly.

[0153] For example, if the first device is a PCP or AP, the first frame structure may be a DMG beacon frame in the current or next BTI, and the PCP or AP uses the fifth information to announce that the PCP or AP is performing monostatic sensing based on a beacon in the current BTI, or uses the fifth information to announce that the PCP or AP should perform monostatic sensing based on a beacon in the next BTI. After the corresponding BTI ends, the STA may request the first sensing result of the monostatic sensing from the PCP or AP. To parse the first sensing result, the STA may also request target beam information for the PCP or AP to transmit a beacon and information about the target position of the PCP or AP transmitting the beacon in the monostatic sensing process from the PCP or AP.

[0154] For example, if the first device is a PCP or AP, the first frame structure may be a data frame in the current or next DTI, and the PCP or AP uses the fifth information to announce that the PCP or AP is performing monostatic sensing based on the data frame in the current DTI, or uses the fifth information to announce that the PCP or AP should perform monostatic sensing based on the data frame in the next DTI. After the corresponding DTI is completed, the STA may request the first sensing result of the monostatic sensing from the PCP or AP. To parse the first sensing result, the STA may also request target beam information for the PCP or AP to transmit the data frame and information about the target position of the PCP or AP that transmits the data frame in the monostatic sensing process from the PCP or AP.

[0155] For example, if the first device is a PCP or AP, the first frame structure may be a BRP in the current or next DTI, and the PCP or AP uses the fifth information to announce that the PCP or AP is performing monostatic sensing based on the BRP in the current DTI, or uses the fifth information to announce that the PCP or AP should perform monostatic sensing based on the BRP in the next DTI. After the corresponding A-BFT is completed, the STA may request the first sensing result of the monostatic sensing from the PCP or AP. To parse the first sensing result, the STA may also request target beam information for the PCP or AP to send the BRP and information about the target position of the PCP or AP that sends the BRP in the monostatic sensing process from the PCP or AP.

[0156] For example, if the first device is a STA, the first frame structure may be an SSW or short SSW in the current or next A-BFT, and the STA uses the fifth information to announce that the STA is performing monostatic sensing based on the SSW / short SSW in the current A-BFT, or the STA uses the fifth information to announce that the STA should perform monostatic sensing based on the SSW / short SSW in the next A-BFT. After the corresponding A-BFT is completed, the AP may request the STA for the first sensing result of the monostatic sensing performed by the STA. To parse the first sensing result, the AP may also request the STA for target beam information for the STA to transmit the SSW / short SSW and information regarding the target position of the STA transmitting the SSW / short SSW in the monostatic sensing process.

[0157] For example, if the first device is a STA, the first frame structure is a data frame in the current or next DTI, and the STA uses the fifth information to announce that the STA is performing monostatic sensing based on the data frame in the current DTI, or the STA uses the fifth information to announce that the STA is performing monostatic sensing based on the data frame in the next DTI. DTI Within Data Frame After the corresponding DTI is completed, the AP may request the STA for the first sensing result of the monostatic sensing performed by the STA. To parse the first sensing result, the AP may also request the STA for target beam information for transmitting data frames by the STA and information about the target position of the STA that transmits data frames in the monostatic sensing process.

[0158] For example, if the first device is a STA, the first frame structure is a BRP in the current or next DTI, and the STA uses the fifth information to announce that the STA is performing monostatic sensing based on the BRP in the current DTI, or the STA uses the fifth information to announce that the STA should perform monostatic sensing based on the BRP in the next DTI. After the corresponding DTI is completed, the AP may request the STA for the first sensing result of the monostatic sensing performed by the STA. To parse the first sensing result, the AP also obtains target beam information for the STA to send a BRP and the first sensing result in the monostatic sensing process. BRP and information about the target location of the STA transmitting the signal.

[0159] The second device may request acquisition of monostatic sensing results from the first device by using a first request frame, and the first device transmits the first sensing results of the monostatic sensing to the second device by using a first response frame. Optionally, the first request frame may be further used to request acquisition of target beam information and target position information. For example, the first request frame may be an information request frame. Optionally, the first request frame may be used to request acquisition of the monostatic sensing results, and the second device requests acquisition of the target beam information and target position information by using a second request frame. For example, the first request frame may be a DMG sensing poll frame, and the second request frame may be an information request frame. Furthermore, the second device parses the first sensing results of the first device based on the acquired target beam information and the acquired target position information.

[0160] In some arbitrary manners, the fifth information may be included in a third frame structure. If the first device is a PCP or an AP, the third frame structure is one or more of the following: an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a DMG beacon frame, an information request frame, an information response frame, a probe request frame, a probe response frame, a data frame, etc. If the first device is a STA, the third frame structure is one or more of the following: an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, an information response frame, a probe request frame, a probe response frame, an SSW frame, a short SSW frame, a data frame, etc.

[0161] For example, the fifth information may be included in a function element of the third frame structure, for example, in a DMG short sensing function element field.

[0162] Optionally, the fifth information may be included in a short sensing capability field within the DMG short sensing capability element. Figures 7a, 7b, and 7c are diagrams of the structure of a short sensing capability field according to the present application. As shown in Figures 7a and 7b, a monostatic sensing field may be added to the short sensing capability field to carry the fifth information. That is, the monostatic sensing field indicates whether the associated device is performing monostatic sensing based on the current transmission or whether monostatic sensing should be performed based on the next transmission. It may be understood that the monostatic sensing field may only indicate that the associated device is performing monostatic sensing based on the current transmission, or that the associated device should perform monostatic sensing based on the next transmission. This is not limited to this application. Alternatively, the monostatic sensing field may indicate that the associated device is performing monostatic sensing based on the current transmission or that the associated device should perform monostatic sensing based on the next transmission.

[0163] In some optional implementations, as shown in FIG. 7c, a first field (e.g., monostatic sensing with current beacon) and a second field (e.g., monostatic sensing with next beacon) may be further added to the short sensing capability field. The first field indicates that monostatic sensing is being performed based on the first frame structure in the current transmission (e.g., a beacon in the current BTI, or an SSW or short SSW in the current A-BFT). The second field indicates that monostatic sensing should be performed based on the first frame structure in the next transmission (e.g., a beacon in the next BTI, or an SSW or short SSW in the next A-BFT). The fifth information is included in the first field or the second field.

[0164] If the first device is a PCP / AP, it can be understood that the PCP / AP performs monostatic sensing based on a data frame, that is, the first frame structure is a data frame. In a possible design, the PCP / AP may announce in a DMG short sensing capability element field of the third frame structure that the PCP / AP is performing monostatic sensing based on a data frame in the current DTI or that it should perform monostatic sensing based on a data frame in the next DTI. The third frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a beacon frame, an information request frame, an information response frame, a data frame, a probe request frame, a probe response frame, etc. For details, please refer to the description of the above embodiment. The details will not be described again here. In another possible implementation, the PCP / AP may also use at least one bit in the allocation field corresponding to the extended schedule element of the DMG beacon frame to indicate that the allocation is performing monostatic sensing based on a data frame in the current DTI or that monostatic sensing should be performed based on a data frame in the next DTI. In yet another possible implementation, the PCP / AP may also add at least one bit to the data frame to indicate that the PCP / AP is performing monostatic sensing based on a data frame in the current DTI or that monostatic sensing should be performed based on a data frame in the next DTI. For example, at least one reserved bit in either the PHY header or the MAC header may be used for the indication.

[0165] If the first device is a STA, it can be understood that the STA performs monostatic sensing based on a data frame, that is, the first frame structure is a data frame. In a possible design, the STA may announce in a DMG short sensing capability element field of the third frame structure that the STA is performing monostatic sensing based on a data frame in the current DTI or that it should perform monostatic sensing based on a data frame in the next DTI. The third frame structure may be an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, an information request frame, a probe request frame, a probe response frame, an information response frame, an SSW frame, a short SSW frame, a data frame, or the like. For details, please refer to the description of the above embodiment. The details will not be described again here.

[0166] Optionally, the STA may use a reserved bit in an SSW frame or short SSW transmitted in the A-BFT to indicate that the STA is performing monostatic sensing based on a data frame in the current DTI or that it should perform monostatic sensing based on a data frame in the next DTI.

[0167] In a possible implementation, the STA may also add at least one bit to the data frame to indicate that the STA is performing monostatic sensing based on the data frame in the current DTI or should perform monostatic sensing based on the data frame in the next DTI. For example, at least one reserved bit in either the PHY header or the MAC header may be used for the indication.

[0168] It can be understood that the technical solution of the present application is not only applicable to high frequencies but also to low frequencies, which is not limited in the present application. The contents of the technical solution may be cross-referenced.

The communication device of the embodiment of the present application will be described in detail below with reference to FIGS. 8 to 10.

[0171] FIG. 8 is a diagram of the structure of a communication device 100 according to an embodiment of the present application. The communication device 100 may correspondingly perform the functions or steps performed by the communication devices (e.g., the first device and the second device) in the above method embodiments.

[0172] In some possible implementations, the communication device 100 may correspondingly perform the operations and functions of the first device in the above method embodiments. For example, the communication device 100 may be the first device, or may be a component (e.g., a chip or circuit) applied to the first device.

[0178] In each implementation of the communication apparatus shown in Figure 9, the transceiver may include a receiver and a transmitter. The receiver is configured to perform receiving functions (or operations), and the transmitter is configured to perform transmitting functions (or operations). The transceiver is configured to communicate with other devices / apparatuses over a transmission medium.

[0179] Optionally, the communication device 200 may further include one or more memories 230 configured to store program instructions and / or data. The memory 230 is coupled to the processor 220. The coupling in this embodiment of the present application may be an indirect coupling or communication connection between devices, units, or modules in an electrical, mechanical, or other form, used for information exchange between the devices, units, or modules. The processor 220 may cooperate with the memory 230 to perform operations. The processor 220 may execute program instructions stored in the memory 230.

[0180] The specific connection medium between the transceiver 210, the processor 220, and the memory 230 is not limited in this embodiment of the present application. In this embodiment of the present application, in FIG. 9, the memory 230, the processor 220, and the transceiver 210 are connected by using a bus 240. The bus is shown by using a thick line in FIG. 9. The connection method of the other components is only an example for explanation and does not imply limitation. The bus may be classified as an address bus, a data bus, a control bus, etc. For ease of representation, only one thick line is used to represent the bus in FIG. 9, but this does not mean that there is only one bus or only one type of bus.

[0181] In this embodiment of the present application, the processor may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, etc. The processor is capable of implementing or executing the methods, steps, and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor may be a microprocessor, or any conventional processor, etc. The steps of the methods disclosed with reference to the embodiments of the present application may be performed directly by a hardware processor, or may be performed by a combination of hardware and software modules in a processor, etc.

[0182] In this embodiment of the present application, memory may include, but is not limited to, a hard disk drive (HDD) or solid-state drive (SSD), random access memory (RAM), erasable programmable read-only memory (EPROM), read-only memory (ROM), or non-volatile memory such as a compact disc read-only memory (CD-ROM). Memory is any storage medium that can be used to carry or store program code in the form of instructions or data structures and that can be read and / or written by a computer (e.g., a communication device as shown in this application). However, the present application is not so limited. Memory in this embodiment of the present application may alternatively be a circuit or any other device capable of implementing a storage function and configured to store program instructions and / or data.

[0183] The processor 220 is primarily configured to process communication protocols and communication data, control the entire communication device, execute software programs, and process data of the software programs. The memory 230 is primarily configured to store software programs and data. The transceiver 210 may include a control circuit and an antenna. The control circuit is primarily configured to convert baseband signals and radio frequency signals and process the radio frequency signals. The antenna is primarily configured to receive and transmit radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, display, or keyboard, is primarily configured to receive data input by a user and output data to a user.

[0184] After the communication device is powered on, the processor 220 can read the software program in the memory 230, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, after performing baseband processing on the data to be transmitted, the processor 220 outputs a baseband signal to the radio frequency circuit, which performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside through an antenna in the form of electromagnetic waves. When data is transmitted to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal to a baseband signal, and outputs the baseband signal to the processor 220. The processor 220 converts the baseband signal to data and processes the data.

[0185] In other implementations, the radio frequency circuitry and antenna may be located independently from the processor that performs the baseband processing, e.g., in a distributed scenario, the radio frequency circuitry and antenna may be located independently and remotely from the communication device.

[0186] It can be understood that the communication device shown in this embodiment of the present application may further include more components than those shown in FIG. 9, etc. This is not limited to this embodiment of the present application. The above methods performed by the processor and transceiver are merely examples. Please refer to the above methods for specific steps performed by the processor and transceiver.

The transmitting unit may be an output interface, and the receiving unit may be an input interface. The transmitting unit and the receiving unit may be integrated into one unit, e.g., an input / output interface. As shown in FIG. 10, the communication device shown in FIG. 10 includes a logic circuit 301 and an interface 302. That is, the processing module 110 may be implemented using the logic circuit 301, and the transceiver module 120 may be implemented using the interface 302. The logic circuit 301 may be a chip, a processing circuit, an integrated circuit, a system on chip (SoC), etc. The interface 302 may be a communication interface, an input / output interface, a pin, etc. FIG. 10 illustrates an example in which the communication device is a chip. The chip includes a logic circuit 301 and an interface 302 .

[0188] In this embodiment of the present application, the logic circuit and the interface may be coupled to each other, and the specific manner of connection between the logic circuit and the interface is not limited in this embodiment of the present application.

[0189] For example, when the communication apparatus is configured to perform a method, function, or step performed by a first device, the logic circuit 301 is configured to perform monostatic sensing based on a first frame structure to obtain a first sensing result, and the interface 302 is configured to receive a first request frame and send a first response frame to a second device.

[0190] For example, when the communication device is configured to perform a method, function, or step performed by a second device, the interface 302 is configured to send a first request frame to the first device and to receive a second location response frame sent by the first device, and the logic circuit 301 is configured to generate the first request frame.

Furthermore, the shown or discussed mutual couplings or direct couplings or communication connections may be implemented through some interface, and indirect couplings or communication connections between devices or units may be implemented in an electrical, mechanical, or other form.

[0198] The units described as separate parts may or may not be physically separated, and the parts shown as units may or may not be physical units, and may be located in one place or distributed over multiple network units.
