Description

Beam information indication method, apparatus and system

[0001] The present application claims priority to the Chinese patent application No. 202410458849.7, filed on April 15, 2024, with the State Intellectual Property Office of China, and the Chinese patent application No. 202410458849.7 has the title of “Beam information indication method, apparatus and system”, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a beam information indication method, apparatus and system. BACKGROUND

[0003] The institute of electrical and electronics engineers (IEEE) 802.11bf is a new generation of wireless standard focusing on passive object (such as target does not carry any device) sensing. The 802.11bf standard includes two categories of standards, low frequency (such as below 7 gigahertz (sub7GHz), the implementation mainly relies on 802.11ac, 802.11ax, 802.11be, 802.11bn and next generation standards, etc.) and high frequency (such as greater than or equal to 60GHz, the implementation mainly relies on 802.11ad, 802.11ay and next generation standards, etc.).

[0004] In the 802.11bf standard, the sensing device can estimate the parameters (such as speed, distance, angle, etc.) of the sensing target based on the signals it receives, and the estimation results can be used for subsequent action / behavior recognition, etc.

[0005] There is a problem of low sensing performance in the existing sensing by proxy (SBP) process. SUMMARY

[0006] The embodiments of the present application provide a beam information indication method, apparatus and system, which can improve the flexibility of beam allocation and improve the sensing performance.

[0007] In a first aspect, the embodiments of the present application provide a method for indicating beam information, which can be applied to a sensing-aware SBP initiator (or sensing-aware initiator). The SBP initiator can include a STA, or a functional module in the STA, or a circuit or chip responsible for communication in the STA, such as a modem chip, a baseband chip, a system on chip (SoC) chip or a system in package (SIP) chip that contains a modem core, etc. The method includes the following steps:

[0008] The SBP initiator sends an SBP request frame, which includes beam indication information. The beam indication information is used to indicate (or configure or suggest or recommend) at least one of a transmit beam list or a receive beam list for each sensing responder in N sensing responders when the SBP responder is suggested (or recommended or indicated) as a sensing initiator by the SBP initiator. The transmit beam list is used to indicate the index of a transmit beam used by the corresponding sensing responder in a sensing measurement session. The receive beam list is used to indicate the index of a receive beam used by the corresponding sensing responder in the sensing measurement session. N is a positive integer. The SBP initiator receives an SBP response frame for the SBP request frame.

[0009] The transmit beam list or the receive beam list shown in the present application can include three cases, i.e., including a transmit beam list, including a receive beam list, and including both a transmit beam list and a receive beam list. The transmit beam in the present application can be a beam used to transmit a sensing PPDU, and the receive beam can be a beam used to receive a sensing PPDU. For example, N can be equal to 1, or N can be greater than or equal to 2.

[0010] The SBP request frame is used to indicate that the SBP responder initiates a sensing measurement session. That is, the sensing measurement session is a session initiated by the SBP responder at the request of the SBP initiator. Alternatively, the sensing measurement session is a session established by the SBP responder at the request of the SBP initiator. Alternatively, the sensing measurement session is a session initiated by the SBP responder based on the SBP request frame.

[0011] In the embodiments of the present application, the SBP initiator can suggest the SBP responder to indicate the transmit beam list or the receive beam list for different sensing responders when the SBP responder acts as a sensing initiator, so that different sensing responders can use different transmit beam lists to transmit signals, or different sensing responders can use different receive beam lists to receive signals. Thus, the SBP initiator assigns the transmit beam list or the receive beam list in combination with the direction in which the sensing responder is located, which can improve the flexibility of beam assignment and improve the sensing performance.

[0012] With reference to the first aspect, in a possible implementation, the method further includes: generating, by the SBP initiator, an SBP request frame.

[0013] With reference to the first aspect, in a possible implementation, the method further includes: receiving, by the SBP initiator, a sensing measurement request frame, the sensing measurement request frame being used to initiate the sensing measurement session, and the sensing measurement request frame including the beam indication information.

[0014] In the embodiments of the present application, the SBP initiator can participate in the current sensing measurement session as a sensing responder. The current sensing measurement session shown herein is a sensing measurement session established by the SBP responder (i.e., the sensing initiator) in response to the requirement of the SBP initiator.

[0015] In the embodiments of the present application, the sensing measurement request frame can be determined based on the SBP request frame (or the SBP response frame), or in other words, the parameters allocated by the sensing initiator to the sensing responders in the sensing measurement request frame can come from the SBP request frame (or the SBP response frame). For example, the beam indication information in the sensing measurement request frame can be the transmit beam list or the receive beam list indicated by the sensing initiator for the N3 sensing responders respectively. N3 is a positive integer less than or equal to N, for example, N3 can be equal to 1, etc. For example, when N3 = 1, the sensing initiator can send a sensing measurement request frame to one sensing responder, and the sensing measurement request frame can include the transmit beam list or the receive beam list indicated for the above-mentioned one sensing responder. The beam indication information in the SBP request frame can be suggested by the SBP initiator, and the SBP responder acting as a sensing initiator can indicate the transmit beam list or the receive beam list to the N sensing responders respectively. Whether the specific form of the beam indication information in the sensing measurement request frame is the same as that in the SBP request frame is not limited in the embodiments of the present application.

[0016] In a second aspect, an embodiment of the present application provides a method for indicating beam information, which can be applied to an SBP response end. The SBP response end can include an AP, or a functional module in the AP, or a circuit or chip responsible for communication in the AP, such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core, etc. The method includes:

[0017] The proxy-aware SBP response end receives an SBP request frame, which includes beam indication information. The beam indication information is used by the SBP response end to indicate at least one of a transmit beam list or a receive beam list for each of N aware response ends when the SBP response end is suggested by the SBP initiator end as an aware initiator end. The transmit beam list is used to indicate the index of a transmit beam used by the corresponding aware response end in an aware measurement session. The receive beam list is used to indicate the index of a receive beam used by the corresponding aware response end in the aware measurement session. N is a positive integer. The SBP response end sends an SBP response frame for the SBP request frame.

[0018] The description of the second aspect can be referred to the first aspect, and details are not repeated here.

[0019] In combination with the second aspect, in a possible implementation, the method further includes:

[0020] The SBP response end parses the SBP request frame and determines the corresponding transmit beam list or receive beam list for each of the N aware response ends based on the beam indication information.

[0021] The aware response end in the aware measurement session includes at least one of the N aware response ends.

[0022] In combination with the second aspect, in a possible implementation, the method further includes:

[0023] The SBP response end sends an aware measurement request frame, which is used to initiate the aware measurement session. The aware measurement request frame includes the beam indication information.

[0024] In combination with the second aspect, in a possible implementation, before the SBP response end sends the aware measurement request frame, the method further includes that the SBP response end generates the aware measurement request frame.

[0025] In the embodiments of the present application, the sensing measurement request frame can be generated by the SBP response end (i.e., the sensing initiation end) based on the parameters suggested by the SBP initiation end in the SBP request frame. The description of the beam indication information in the sensing measurement request frame and the beam indication information in the SBP request frame can refer to the first aspect, and will not be described in detail here.

[0026] In a possible implementation manner, in combination with the first aspect or the second aspect, the beam indication information includes one sending beam list and N receiving beam lists indicated for the N sensing response ends, and each receiving beam list corresponds to one sensing response end; or the beam indication information includes one receiving beam list and N sending beam lists indicated for the N sensing response ends, and each sending beam list corresponds to one sensing response end; or the beam indication information includes N sending beam lists and N receiving beam lists indicated for the N sensing response ends, and each sending beam list corresponds to one sensing response end, and each receiving beam list corresponds to one sensing response end.

[0027] In the embodiments of the present application, as an example, the above content of the beam indication information can be defined by a protocol. For example, the content of the beam indication information can be set as N sending beam lists and N receiving beam lists indicated for N sensing response ends by default. As another example, the content of the beam indication information can correspond to the sensing type. The SBP initiation end sets the content of the beam indication information in combination with the sensing type or the role of each sensing response end, so that the content of the beam indication information is more matched with the sensing type.

[0028] In a possible implementation manner, in combination with the first aspect or the second aspect, the SBP request frame includes information of recommended sensing response ends, and the information of the N sensing response ends is included in the information of the recommended sensing response ends.

[0029] In the embodiments of the present application, the order of the N sensing response ends in the information of the recommended sensing response ends can correspond to the order of the N sensing response ends corresponding to the sending beam list or the receiving beam list indicated by the beam indication information. In other words, the order of each sensing response end in the information of the recommended sensing response ends can one-to-one correspond to the sensing response end corresponding to the sending beam list (or the receiving beam list) in the beam indication information in turn. For example, the information of the recommended sensing response ends can include information of M sensing response ends. M is greater than or equal to N. For example, the nth sending beam list (or the nth receiving beam list) in the beam indication information can correspond to the nth sensing response end in the information of the recommended sensing response ends. For another example, the N sensing response ends corresponding to the beam indication information can be located at a fixed position in the information of the recommended sensing response ends.

[0030] In the embodiments of the present application, the SBP request frame includes the information of the recommended sensing response end, so that the SBP response end can clearly know which sensing response end the transmission beam list or the reception beam list indicated by the beam indication information corresponds to.

[0031] In a possible implementation manner, in combination with the first aspect or the second aspect, the SBP request frame further includes a role bitmap, the role bitmap being used to indicate a role of each of the N sensing response ends, the role of the sensing response end being at least one of a sensing transmission end or a sensing reception end.

[0032] In the embodiments of the present application, the SBP request frame includes the role bitmap, so that the SBP response end can know the content indicated by the beam indication information based on the role bitmap, or can know the sensing type, thereby making it more convenient to analyze the beam indication information.

[0033] In a possible implementation manner, in combination with the first aspect or the second aspect, the SBP request frame further includes a beam list number, the beam list number being used to indicate a number of beam list pairs of the transmission beam list and the reception beam list; or the SBP request frame further includes a beam list existence, the beam list existence being used to indicate whether the beam indication information exists in the SBP request frame.

[0034] In the embodiments of the present application, the SBP request frame includes the beam list number, so that the SBP response end can effectively know how many sensing response ends are recommended by the SBP request frame based on the beam list number. The SBP request frame includes the beam list existence, so that the SBP response end can effectively know whether the SBP request frame includes the beam indication information. Of course, the SBP request frame can also include the beam list number and the beam list existence at the same time.

[0035] In a possible implementation manner, in combination with the first aspect or the second aspect, the SBP request frame further includes at least one of the following: a number of sensing response ends, a number of sensing response ends being mandatory, a number of recommended sensing response ends, a recommended sensing response end list existence, and recommended sensing response ends being mandatory.

[0036] In a possible implementation manner, in combination with the first aspect or the second aspect, the SBP request frame further includes at least one of the following: an SBP procedure expiration index, and a sensing response end to sensing response end (SR2SR) probe request.

[0037] In a possible implementation manner, the beam indication information is carried in an integrated millimeter wave (IMMW) SBP parameter element or an IMMW sensing measurement parameter element in the SBP request frame.

[0038] In a possible implementation manner, the beam indication information is carried in a directional multi-gigabit (DMG) SBP parameter element in the SBP request frame.

[0039] In a possible implementation manner, the beam indication information is carried in an SBP parameter element in the SBP request frame.

[0040] In a possible implementation manner, the SBP initiator comprises a module for executing the method in the first aspect or any possible implementation manner.

[0041] In a possible implementation manner, the SBP responder comprises a module for executing the method in the second aspect or any possible implementation manner.

[0042] In a possible implementation manner, the SBP initiator comprises a processor for executing the method in the first aspect or any possible implementation manner.

[0043] In a possible implementation manner, the memory is located outside the SBP initiator.

[0044] In a possible implementation manner, the memory is located inside the SBP initiator.

[0077] For the purpose of understanding the technical solutions of the present application, the present application will be further described below with reference to the drawings.

[0078] The terms "first" and "second" and the like in the description, claims, and drawings of the present application merely mean to distinguish different objects, and are not intended to describe a particular order. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device, etc. comprising a series of steps or units is not limited to the listed steps or units, but can optionally further comprise steps or units not listed, etc., or can optionally further comprise other steps or units inherent to the process, method, product, or device, etc.

[0079] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It will be apparent to those skilled in the art from the descriptions herein that the embodiments described herein can be combined with other embodiments.

[0080] In the present application, "at least one" means one or more, "multiple" means two or more, "at least two" means two or three and more, and "and / or" is used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, "A and / or B" can mean that there are three cases: only A, only B, and A and B exist at the same time, where A and B can be singular or plural. "Or" means that there can be two relationships, such as only A, only B; when A and B are not mutually exclusive, it can also mean that there are three relationships, such as only A, only B, and A and B exist at the same time. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items. For example, at least one of a, b, or c can mean a, b, c, "a and b", "a and c", "b and c", or "a and b and c".

[0081] In this application, the "indication" can include direct indication, indirect indication, display indication, implicit indication. When describing that certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0082] In this application, the information indicated by the indication information is referred to as the to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be only indicated in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the pre-agreed (for example, the protocol stipulates) arrangement order of each information, thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending opportunity of these sub-information can be the same or different.

[0083] In this application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between network devices and terminal devices, or can be carried out within a device, for example, between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0084] The following introduces the communication system related to the present application.

[0085] The technical solutions provided in the embodiments of the present application can be applied to a wireless local area network (WLAN) system, such as Wi-Fi or ambient power (AMP). The method provided in the embodiments of the present application can be applicable to IEEE 802.11 series protocols, for example, 802.11a / b / g protocols, 802.11bf protocols, 802.11az protocols, 802.11bk protocols, 802.11n protocols, 802.11ac protocols, 802.11ax protocols, 802.11be protocols, 802.11bn protocols, or next-generation protocols, and the like. For example, 802.11ad protocols, 802.11ay or next-generation protocols, and the like, which are not listed one by one. The technical solutions provided in the embodiments of the present application can also be applied to a wireless personal area network (WPAN) based on ultra wideband (UWB) technology. The technical solutions provided in the embodiments of the present application can also be applied to millimeter wave (MMW) technology, including integrated MMW (IMMW) (hereinafter taking IMMW as an example). The method provided in the embodiments of the present application can be applicable to IEEE 802.15 series protocols, for example, 802.15.4a protocols, 802.15.4z protocols, or 802.15.4ab protocols, or future generations of UWB WPAN protocols, and the like, which are not listed one by one. The technical solutions provided in the embodiments of the present application can also be applied to a communication system, for example, can be an internet of things (IoT) system, a vehicle to X (V2X) system, a narrow band IoT (NB-IoT) system, a long term evolution (LTE) system, a 5th-generation (5G) communication system, and a new communication system to be appeared in future communication development, and the like.

[0086] The WLAN system can provide high-rate and low-latency transmission. As the WLAN application scenarios evolve, the WLAN system will be applied to more scenarios or industries, such as the Internet of Things industry, the Internet of Vehicles industry, the banking industry, enterprise offices, stadiums, exhibition halls, concert halls, hotel rooms, dormitories, wards, classrooms, supermarkets, squares, streets, production workshops, and warehouses. Of course, the devices (such as access points or stations) that support WLAN communication or sensing can be sensor nodes in smart cities (such as smart water meters, smart electricity meters, and smart air detection nodes), smart devices in smart homes (such as smart cameras, projectors, display screens, televisions, sound systems, refrigerators, washing machines, and the like), nodes in the Internet of Things, entertainment terminals (such as augmented reality (AR) and virtual reality (VR) wearable devices), smart devices in smart offices (such as printers, projectors, amplifiers, sound systems, and the like), Internet of Vehicles devices in the Internet of Vehicles, infrastructure in daily life scenarios (such as vending machines, self-service navigation stations in supermarkets, self-service checkout devices, and self-service ordering machines), and devices in large sports and music venues.

[0087] Although the embodiments of the present application mainly take WLAN as an example, especially the network applying to the IEEE 802.11 series standards. The various aspects of the embodiments of the present application can be extended to other networks using various standards or protocols. For example, Bluetooth, high performance radio LAN (HIPERLAN) (a wireless standard similar to the IEEE 802.11 standard, mainly used in Europe), and wide area network (WAN) or other now known or later developed networks.

[0088] In a possible implementation, the method provided by the embodiments of the present application can be implemented by a communication device in a communication system. For example, the communication device can be an access point (AP) or a station (STA).

[0089] The access point is a device with wireless communication function, which supports communication or sensing using WLAN protocol, has the function of communicating or sensing with other devices (such as non-AP STA or other access points) in the WLAN network, and of course, can also have the function of communicating or sensing with other devices. Alternatively, the access point is equivalent to a bridge connecting wired and wireless networks, and its main function is to connect various wireless network clients together and then access the wireless network to the Ethernet. In the WLAN system, the access point can be referred to as an access point station (AP STA). The device with wireless communication function can be a whole device, or a chip, processing system or functional module installed in the whole device, and the device installed with the chip or processing system or functional module can realize the method and function of the embodiments of the present application under the control of the chip or processing system or functional module. The AP in the embodiments of the present application is a device providing services for non-AP STA, which can support 802.11 series protocol or subsequent protocol, etc. For example, the access point can be an access point for terminals (such as mobile phones) to enter wired (or wireless) networks, which is mainly deployed in homes, buildings and parks, and the typical coverage radius is dozens of meters to hundreds of meters, and of course, it can also be deployed outdoors. For another example, the AP can be a communication server, a router, a switch, a network bridge and other communication entities; the AP can include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP can also be a chip or processing system or module in the above various forms of devices, so as to realize the method and function of the embodiments of the present application. Of course, the AP can also include an AP belonging to a multi-link device (MLD).

[0090] A STA is a device with wireless communication function, which supports communication or sensing using WLAN protocol, and has the ability to communicate or sense with other non-AP STAs or access points in a WLAN network. In a WLAN system, a station can be referred to as a non-access point station (non-AP STA). For example, a STA is any user communication device that allows a user to communicate or sense with an AP and then communicate with a WLAN. The device with wireless communication function can be a whole device, or a chip or processing system or functional module installed in a whole device. The device in which the chip or processing system or functional module is installed can realize the methods and functions of the embodiments of the present application under the control of the chip or processing system or functional module. For example, a STA can be a wireless communication chip, a wireless sensor or a wireless communication terminal, and can also be referred to as a user. For another example, a STA can be a mobile phone supporting Wi-Fi communication function, a tablet computer supporting Wi-Fi communication function, a set-top box supporting Wi-Fi communication function, a smart television supporting Wi-Fi communication function, a smart wearable device supporting Wi-Fi communication function, a vehicle-mounted communication device supporting Wi-Fi communication function, and a computer supporting Wi-Fi communication function. Of course, a STA can also be a chip or processing system or module in the above various forms of devices, thereby realizing the methods and functions of the embodiments of the present application. Of course, a STA can also include a non-AP STA belonging to a multi-link device (MLD).

[0091] For example, the communication system to which the method provided by the embodiments of the present application can be applied can include an access point and a station. For example, the embodiments of the present application can be applicable to a scenario of communication or sensing between an AP and a STA, between an AP and an AP, or between a STA and a STA in a WLAN, and the embodiments of the present application are not limited thereto. Optionally, an AP can communicate or sense with a single STA, or an AP can simultaneously communicate or sense with multiple STAs. Specifically, the communication or sensing between an AP and multiple STAs can be divided into downlink transmission in which an AP simultaneously sends signals to multiple STAs, and uplink transmission in which multiple STAs send signals to an AP. The communication between an AP and a STA, between an AP and an AP, and between a STA and a STA can support a WLAN communication protocol, which can include an IEEE 802.11 series protocol, such as an 802.11n / 802.11ac / 802.11ax / 802.11be / 802.11bn protocol, and of course is also applicable to a protocol after 802.11bn.

[0092] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. The communication system can include one or more APs and one or more STAs. In FIG. 1, one access point, e.g., AP1, and three stations, e.g., STA1, STA2 and STA3, are shown. For example, the method provided by the embodiments of the present application can be applied to data communication between one AP and one or more STAs (e.g., communication between AP1 and STA1, or communication between AP1 and STA1 and STA2, as shown in FIG. 1), or applied to communication between APs, or applied to communication between STAs (e.g., communication between STA2 and STA3, as shown in FIG. 1). The method provided by the embodiments of the present application can be applied to, but not limited to, single-user uplink / downlink transmission, multi-user uplink / downlink transmission, vehicle-to-everything (V2X, X can represent any thing), device-to-device (D2D). For example, the V2X can include vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P) or vehicle-to-network (V2N) communication, etc.

[0093] It can be understood that the STA is a mobile phone and the AP is a router in FIG. 1 as an example, which does not limit the type of AP and STA in the embodiments of the present application. Meanwhile, FIG. 1 only shows one AP and three STAs as an example, but the number of APs or STAs can be more or less, which is not limited in the embodiments of the present application.

[0094] Some devices related to the embodiments of the present application are introduced below.

[0095] Sensing initiator: a device that initiates a sensing behavior; or a device that initiates a sensing measurement session; or a device that sends a sensing measurement request frame. For example, the sensing initiator can send a sensing measurement request frame at a low frequency, or send a sensing measurement request frame at a high frequency. The sensing initiator can be a sensing transmitter or a sensing receiver.

[0096] Sensing responder: a device that participates in sensing in response to sensing behavior initiated by a sensing initiator. For example, a sensing responder can receive a sensing measurement request frame and reply with a sensing measurement response frame. For example, a sensing responder can reply with a sensing measurement response frame at low frequencies or at high frequencies. As an example, for a trigger-based (TB) sensing measurement exchange, a sensing initiator can be an AP and a sensing responder can be a STA. As another example, for a non-TB sensing measurement exchange, a sensing initiator can be a STA and a sensing responder can be an AP. A sensing responder can be a sensing transmitter or a sensing receiver.

[0097] Sensing transmitter: a device that transmits a sensing PPDU. For example, a sensing transmitter can transmit a sensing PPDU at low frequencies or at high frequencies.

[0098] Sensing receiver: a device that receives a sensing PPDU. For example, a sensing receiver can receive a sensing PPDU at low frequencies or at high frequencies.

[0099] In this application, high frequencies and low frequencies are relative. For example, low frequencies can be below a first threshold, such as below 7 GHz (sub-7 GHz), or low frequencies can include 2.4 GHz - 7.25 GHz (also referred to as sub-7 GHz). High frequencies can be above a second threshold, such as above 42 GHz, or high frequencies can include 42 GHz - 71 GHz. The second threshold can be greater than the first threshold. The specific values of the first threshold and the second threshold are not limited in this application. Of course, as the standard evolves, other frequencies of high frequencies and low frequencies can appear in the future, which are not limited in this application.

[0100] FIG. 2 is a schematic diagram of stages of a sensing procedure according to an embodiment of the present application. As shown in FIG. 2, the stages of the sensing procedure can include a sensing capabilities exchange stage, a sensing measurement session establishment stage, a sensing measurement exchange stage, and a sensing measurement session termination stage.

[0101] In the sensing capability exchange phase, the devices can exchange their sensing capabilities. Through the exchange of the basic capabilities, the devices can learn each other's sensing capabilities. For example, the sensing initiator can send a sensing capability element to the sensing responder, which can carry the sensing capability of the sensing initiator. The sensing responder can send a sensing capability element to the sensing initiator, which can carry the sensing capability of the sensing responder. Generally, in the sensing capability exchange phase, the devices that exchange capabilities are not distinguished as sensing initiators or sensing responders. The sensing initiator or the sensing responder can be distinguished after the completion of the capability exchange, i.e., the device that sends the sensing measurement request frame can be the sensing initiator.

[0102] After the sensing devices complete the capability exchange, when it is necessary to initiate a sensing measurement session, the sensing initiator can initiate the establishment of the sensing measurement session by sending a sensing measurement request frame (or simply referred to as a sensing measurement request), and the sensing responder receives the sensing measurement request and replies with a sensing measurement response frame (or simply referred to as a sensing measurement response). Through the sensing measurement session establishment phase, the sensing initiator can assign different roles (such as the role of a sensing transmitter, the role of a sensing receiver, the role of a sensing initiator, the role of a sensing responder), parameters, etc. to different sensing responders for different sensing tasks, thereby completing the establishment of the sensing measurement session. In this sensing measurement session establishment phase, the relevant parameters in sensing are mainly negotiated, such as the receiving / transmitting role of the device, the sensing bandwidth, whether to feed back the channel state information (CSI) matrix, whether to feed back the sensing measurement report frame, etc.

[0103] After the establishment of the sensing measurement session, the sensing initiator can initiate one or more sensing measurement instances. That is, one or more sensing measurement instances can be included in the sensing measurement session. For example, the sensing measurement instance can be classified as a trigger based (TB) sensing measurement instance and a non-trigger based (Non-TB) sensing measurement instance. The TB sensing measurement instance is generally initiated by the AP (e.g., the AP as the sensing initiator), and the Non-TB sensing measurement instance is generally initiated by the STA (e.g., the STA as the sensing initiator). The classification of the sensing measurement instance is merely an example. For the sensing procedure of the IMMW, the sensing measurement instance can be classified as the TB sensing measurement instance and the Non-TB sensing measurement instance, or can not be classified as the TB sensing measurement instance and the Non-TB sensing measurement instance. The specific classification of the sensing measurement instance is not limited in the present application.

[0104] After a period of time, if the sensing initiator or the sensing responder does not need the sensing measurement session, the sensing initiator or the sensing responder can close (or terminate) the sensing measurement session by sending a sensing measurement session termination frame, as shown in the sensing measurement session termination stage of FIG. 2.

[0105] The sensing procedure shown in FIG. 2 can correspond to different sensing tasks. For example, the sensing initiator can initiate the sensing procedure for a fall detection task, and in the sensing measurement instance stage, the sensing initiator (or the sensing responder) can detect information of the target by sending a plurality of sensing PPDUs. For another example, the sensing initiator can initiate the sensing procedure for a breathing detection task, and in the sensing measurement instance stage, the sensing initiator (or the sensing responder) can also detect information of the target by sending a plurality of sensing PPDUs. The information of the target listed herein can include motion information of the target, etc. The target detected by the sensing procedure can be in a motion state or in a stationary state, and the embodiments of the present application are not limited thereto.

[0106] As an example, the above four stages can be applicable to sensing below 7 GHz (Sub 7GHz).

[0107] As another example, the above four stages can be applied to DMG sensing. When applied to DMG sensing, the names of the above four stages can be DMG sensing capability negotiation stage, DMG sensing measurement session setup stage, DMG sensing measurement interaction stage, and DMG sensing measurement session termination stage, respectively. Similarly, the sensing measurement request can also be referred to as DMG sensing measurement request, and the sensing measurement response can also be referred to as DMG sensing measurement response.

[0108] As another example, the above four stages can be applied to IMMW sensing procedure. When applied to IMMW sensing, the names of the above four stages can be IMMW sensing capability negotiation stage, IMWW sensing measurement session setup stage, IMMW sensing measurement interaction stage, and IMMW sensing measurement session termination stage, respectively. Similarly, the sensing measurement request can also be referred to as IMMW sensing measurement request, and the sensing measurement response can also be referred to as IMMW sensing measurement response. The names of the stages or frames or devices are not limited in the embodiments of the present application when the sensing procedure is applied to different frequency bands.

[0109] For DMG sensing or IMMW sensing, since the signal is transmitted directionally, the allocation of sensing beams can be performed in the establishment stage of the sensing measurement session regardless of the sensing type. The sensing type can include but is not limited to monostatic (or single-base) sensing (or coordinated monostatic (or coordinated single-base) sensing), bistatic (or double-base) sensing (or coordinated bistatic (or coordinated double-base) sensing), and multistatic sensing. For example, monostatic sensing can be referred to as self-transmitting and self-receiving sensing, and coordinated monostatic sensing can be referred to as coordinated self-transmitting and self-receiving sensing. Multistatic sensing can include one-transmitting and multiple-receiving sensing or one-receiving and multiple-transmitting sensing.

[0110] The procedure shown in FIG. 2 is only an example, and other sensing procedures can also appear in the future as the standard evolves, which are not limited in the present application.

[0111] The following describes some other devices related to the embodiments of the present application.

[0112] Sensing by proxy (SBP) initiator: a device that initiates the SBP procedure, or a device that initiates the SBP request frame. Generally, the SBP initiator can be a STA. For example, the SBP initiator can send the SBP request frame at low frequency, or send the SBP request frame at high frequency.

[0113] SBP response end: an apparatus responding to the SBP procedure, or an apparatus receiving the SBP request frame and replying the SBP response frame. Generally, the SBP response end can be an AP. The SBP response end can send the SBP response frame at low frequency, or send the SBP response frame at high frequency.

[0114] FIG. 3 is a schematic diagram of the SBP procedure according to an embodiment of the present application. As shown in FIG. 3, STA1 sends an SBP request frame to an AP as an SBP initiating end. The AP, as an SBP response end, after receiving the SBP request frame (referred to as SBP request in FIG. 3 for short), establishes sensing with a corresponding sensing response end according to parameters carried in the SBP request frame, completes measurement and feedback. For example, after receiving the SBP request frame, the AP replies an SBP response frame (referred to as SBP response in FIG. 3 for short). The AP can initiate a sensing measurement session as a sensing initiating end, for example, the AP can send sensing measurement request frames to STA1 and STA2 respectively. The sensing measurement interaction initiated by the AP as the sensing initiating end is generally TB sensing measurement interaction. The description of the TB sensing measurement interaction can refer to the foregoing description of FIG. 2, and will not be repeated here.

[0115] FIG. 3 is an example in which STA1 is both an SBP initiating end and a sensing response end. In a specific implementation, STA1 can not participate in the sensing measurement session initiated by the SBP response end (i.e., STA1 can not be a sensing response end). The sensing measurement request sent by the AP to STA1 or STA2 in FIG. 3 is only an example, and should not be construed as a limitation on the embodiments of the present application. The order between the SBP response and the sensing measurement request in FIG. 3 is not limited in the embodiments of the present application. The description of the sensing measurement request and the sensing measurement response in FIG. 3 can refer to the foregoing description, and will not be repeated here.

[0116] For example, the SBP procedure can further include a feedback phase (not shown in FIG. 3) and a closing phase (not shown in FIG. 3). For example, in the feedback phase of the SBP (not shown in FIG. 3), the AP as the SBP response end can collect the sensing measurement results and then feed back to the SBP initiating end (e.g., STA1). In the closing phase of the SBP (not shown in FIG. 3), the SBP initiating end can close the established SBP procedure. The closing phase shown in the embodiments of the present application can also be referred to as a termination phase, and the specific name of each phase is not limited in the present application.

[0117] As an example, the SBP procedure described above can be applied to sensing for sub-7GHz. The SBP request (or referred to as sub-7GHz SBP request) can carry SBP parameters element and sensing measurement parameters element. Of course, the SBP parameters element and the sensing measurement parameters element can also be set as one element, which is not limited in the embodiments of the present application. The SBP parameters element can carry the related parameters (such as the number of response ends, etc.) of the sensing measurement session initiated by the SBP response end (i.e. the sensing initiator) suggested (or indicated or allocated or specified) by the SBP initiator. The sensing measurement parameters element can carry the sensing parameters (such as the bandwidth, etc.) of the sensing measurement session performed by the sensing response end allocated / specified by the SBP response end suggested by the SBP initiator to the SBP response end. The sub-7GHz SBP procedure initiated by the SBP request can correspond to one or more sensing measurement sessions, which are initiated by the SBP response end as the sensing initiator based on the SBP request (or the SBP response).

[0118] As another example, the SBP procedure described above can be applied to sensing for DMG (i.e. DMG SBP procedure). When applied to sensing for DMG, the SBP initiator can also be referred to as DMG SBP initiator, and the SBP response end can also be referred to as DMG SBP response end. Similarly, the SBP request can also be referred to as DMG SBP request, and the SBP response can also be referred to as DMG SBP response. The SBP request can carry DMG SBP parameters element and DMG sensing measurement parameters element. Of course, the DMG SBP parameters element and the DMG sensing measurement session element can also be set as one element, which is not limited in the embodiments of the present application. The description of the DMG SBP parameters element and the DMG sensing measurement session element can refer to the description of the SBP parameters element and the sensing measurement parameters element above, which will not be described in detail here. The DMG SBP procedure initiated by the DMG SBP request can correspond to one or more sensing measurement sessions, which are initiated by the SBP response end as the sensing initiator based on the SBP request (or the SBP response).

[0119] As another example, the above SBP procedure can be applied to sensing of IMMW (i.e., IMMW SBP procedure). When applied to sensing of IMMW, the SBP initiator can also be referred to as an IMMW SBP initiator, and the SBP responder can also be referred to as an IMMW SBP responder. Similarly, the SBP request can also be referred to as an IMMW SBP request, and the SBP response can also be referred to as an IMMW SBP response. The SBP request can carry an IMMWSBP parameter element and an IMMW sensing measurement parameter element. Of course, the IMMWSBP parameter element and the IMMW sensing measurement parameter element can also be set as one element, and embodiments of the present application do not limit this. The description of the IMMWSBP parameter element and the IMMW sensing measurement parameter element can refer to the description of the SBP parameter element and the sensing measurement parameter element above, and will not be described in detail here. The IMMW SBP procedure initiated by the IMMW SBP request can correspond to one or more sensing measurement sessions, which are sessions initiated by the SBP responder as a sensing initiator based on the SBP request (or the SBP response).

[0120] The SBP procedure described above, which is applied to sensing of sub-7 GHz (or referred to as sub-7 GHz SBP procedure), can be understood as follows: the sensing PPDUs involved in the sensing measurement session corresponding to the sub-7 GHz SBP procedure initiated by the SBP request can be transmitted in the frequency band involved in sub-7 GHz. As for whether other frames in the sensing measurement session except for the sensing PPDUs are transmitted in the frequency band involved in sub-7 GHz, embodiments of the present application do not limit this. The SBP procedure described above, which is applied to sensing of DMG (or referred to as DMG SBP procedure), can be understood as follows: the sensing PPDUs involved in the sensing measurement session corresponding to the DMG SBP procedure initiated by the SBP request can be transmitted in the frequency band involved in DMG. As for whether other frames in the sensing measurement session except for the sensing PPDUs are transmitted in the frequency band involved in DMG, embodiments of the present application do not limit this. The SBP procedure described above, which is applied to sensing of IMMW (or referred to as IMMW SBP procedure), can be understood as follows: the sensing PPDUs involved in the sensing measurement session corresponding to the IMMW SBP procedure initiated by the SBP request can be transmitted in the frequency band involved in IMMW. As for whether other frames in the sensing measurement session except for the sensing PPDUs are transmitted in the frequency band involved in IMMW, embodiments of the present application do not limit this. The transmission shown in the present application can include sending or receiving.

[0121] When the SBP procedure is applied to different frequency bands, the format of the SBP parameter element, the DMG SBP parameter element, or the IMMW SBP parameter element (or the MMW SBP parameter element) can have one or at least two different fields; or the formats of the three elements can be the same; or the three elements can have one or at least two same fields but different field values, and the like, which are not listed one by one here. Similarly, the format of the sensing measurement parameter element, the DMG sensing measurement parameter element, the IMMW sensing measurement parameter element (or the MMW sensing measurement parameter element) can have one or at least two different fields; or the formats of the three elements can be the same; or the three elements can have one or at least two same fields but different field values, and the like, which are not listed one by one here.

[0122] When the SBP procedure is applied to different frequency bands, the name of each frame or device is not limited in the embodiments of the present application. The name of each element in the frame is also not limited in the embodiments of the present application. The names of the DMG SBP parameter element, the IMMW SBP parameter element, the DMG sensing measurement parameter element, or the IMMW sensing measurement parameter element shown above are only examples and should not be understood as a limitation on the embodiments of the present application.

[0123] The present application is illustrated by taking the SBP initiator as the STA and the SBP responder (i.e., the sensing initiator) as the AP as an example. With the development of standards, other devices can implement the sensing procedure or the SBP procedure in the future. The specific product form of the SBP initiator or the SBP responder is not limited in the embodiments of the present application.

[0124] The above description about FIG. 2 or FIG. 3 also applies to the method shown in FIG. 4 and the like below, which is not repeated hereinafter.

[0125] The method involved in the present application is introduced below.

[0126] For the current DMG SBP sensing, the function field (Action field) of the DMG SBP request frame is as follows:

[0127] Table 1

[0128] The order in Table 1 can be the order of fields in the function field in the DMG SBP request frame. The embodiments of the present application are not limited to the order shown in Table 1. For ease of description, the embodiments of the present application are illustrated by taking "fields" or "elements" as examples, and "fields" or "subfields", "elements" or "subelements" are not specifically distinguished. Although the embodiments of the present application do not specifically distinguish "fields", "subfields", "elements", "subelements", but those skilled in the art can adaptively distinguish the relationship between each field shown in the embodiments of the present application.

[0129] In Table 1, the DMG SBP parameter element can carry information of a sensing measurement session that the DMG SBP initiator wants the AP (i.e., the DMG SBP responder or the sensing initiator) to proxy to establish. The information can include, but is not limited to, the number of sensing responders participating in the sensing measurement session, whether there is a preferred sensing responder, etc.

[0130] In Table 1, the DMG sensing measurement session element can carry parameters such as the type of the sensing measurement session that the DMG SBP initiator wants the AP (i.e., the DMG SBP responder or the sensing initiator) to proxy to establish, whether to use polarization measurement, etc. After obtaining the DMG sensing measurement session element, the AP can assign the parameters in the element to all sensing responders. In other words, the AP can assign the same parameters to all sensing responders according to the DMG sensing measurement session element in the DMG SBP request frame.

[0131] For example, the AP can allocate sensing beams through the transmission beam list (TX beamlist) and the reception beam list (RX beamlist) in the optional subelement (or called sensing subelement, etc.) field in the DMG sensing measurement session element in the DMG sensing measurement request frame. That is, the same parameters mentioned above can include the transmission beam list and the reception beam list. The sensing initiator can assign the same transmission beam list and the same reception beam list to different sensing responders.

[0132] Generally, the same sensing target can be located in different directions of multiple sensing responders. Assigning the same transmission beam list and the same reception beam list to different sensing responders by the sensing initiator not only causes different sensing responders to be unable to effectively sense different directions, but also causes these sensing responders to be difficult to implement joint sensing on the same sensing target or the same area, affects the flexibility of sensing, and reduces the sensing performance.

[0133] In view of this, the embodiments of the present application provide a beam information indication method, device and system, which can effectively improve the flexibility of sensing and improve the sensing performance.

[0134] FIG. 4 is a flow diagram of a method for indicating beam information according to an embodiment of the present application. The descriptions of the SBP initiator and the SBP responder in the method can refer to the descriptions in FIG. 1 or FIG. 2 or FIG. 3, which will not be repeated here. As shown in FIG. 4, the method includes the following steps.

[0135] 401. The SBP initiator sends an SBP request frame, which includes beam indication information. The beam indication information is used by the SBP initiator to indicate a list of transmit beams or a list of receive beams for each of the N sensing responders when the SBP responder is suggested to be a sensing initiator.

[0136] Correspondingly, the SBP responder receives the SBP request frame.

[0137] In a possible implementation, the SBP initiator can generate the SBP request frame before sending the SBP request frame. The description of the SBP request frame can refer to the following description, which will not be repeated here.

[0138] 402. The SBP responder sends an SBP response frame, and correspondingly, the SBP initiator receives the SBP response frame.

[0139] After receiving the SBP request frame, the SBP responder can parse the SBP request frame to obtain the parameters indicated by the SBP initiator. When the SBP responder initiates a sensing measurement session as a sensing initiator, the SBP responder can allocate (or suggest or recommend) parameters for the N sensing responders based on the parameters indicated by the SBP initiator. The parameters shown here can include the list of transmit beams or the list of receive beams shown below.

[0140] In a possible implementation, after receiving the SBP request frame, the SBP responder can also generate an SBP response frame. The SBP response frame can include a feedback result of the parameters carried in the SBP request frame. For example, the SBP response frame can include a status code field, which can carry at least one of the following fields: success, rejected with suggested changes, request declined. The "success" indicates that the SBP responder agrees with the request of the SBP initiator. The "request declined" and "rejected with suggested changes" both indicate that the SBP responder rejects the request of the SBP initiator. Optionally, when the status code field carries "rejected with suggested changes", the SBP responder can carry the suggested parameters, which can include but are not limited to the list of transmit beams or the list of receive beams allocated by the SBP responder for at least one of the N sensing responders.

[0141] In a possible implementation, after receiving the SBP response frame, the SBP initiator can parse the SBP response frame. The SBP initiator learns whether the SBP responder agrees with the request of the SBP initiator by parsing the SBP response frame.

[0142] In a possible implementation, the SBP responder can also send a sensing measurement request frame to one or more sensing responders, and the sensing measurement request frame can be used to initiate a sensing measurement session. When the SBP initiator participates in the sensing measurement session as a sensing responder, the SBP initiator can also receive the sensing measurement request frame.

[0143] The sensing measurement request frame can be determined based on the SBP request frame (or the SBP response frame), or in other words, the parameters allocated by the SBP responder as a sensing initiator to the sensing responders in the sensing measurement request frame can come from the SBP request frame (or the SBP response frame). For example, the beam indication information in the sensing measurement request frame can be a list of transmission beams or a list of reception beams respectively indicated by the sensing initiator to the N3 sensing responders. N3 is a positive integer less than or equal to N, for example, N3 can be equal to 1. The beam indication information in the SBP request frame can be a list of transmission beams or a list of reception beams respectively suggested by the SBP initiator to the SBP responder as a sensing initiator to the N sensing responders. Whether the specific form of the beam indication information in the sensing measurement request frame is the same as that in the SBP request frame is not limited in the embodiments of the present application.

[0144] The relationship between the sensing measurement request frame and the SBP request frame (or the SBP response frame) can be referred to the description of FIG. 2 or FIG. 3, which will not be described in detail herein.

[0145] In the embodiments of the present application, the SBP initiator can indicate to the SBP responder the list of transmission beams or the list of reception beams respectively indicated by the SBP responder as a sensing initiator to different sensing responders, so that different sensing responders can use different lists of transmission beams to transmit signals, or different sensing responders can use different lists of reception beams to receive signals. Therefore, the SBP initiator allocates the list of transmission beams or the list of reception beams in combination with the direction in which the sensing responder is located, which can improve the flexibility of beam allocation and improve the sensing performance.

[0146] The information of the SBP request frame involved in the embodiments of the present application is described below.

[0147] The SBP request frame can include at least one of the following: beam indication information, information of recommended sensing responders, role bitmap, number of beam lists, or existence of beam lists. The following is described respectively.

[0148] (1) beam indication information

[0149] The beam indication information is used for the SBP initiator to suggest (or recommend or indicate) to the SBP responder a list of transmission beams or a list of reception beams to be respectively indicated to each of the N sensing responders when the SBP responder acts as a sensing initiator. That is, the SBP initiator can suggest (or recommend or configure) to the SBP responder at least one of a list of transmission beams or a list of reception beams to be allocated by the sensing initiator to each of the N sensing responders when the sensing initiator initiates a sensing measurement session.

[0150] In the embodiments of the present application, the list of transmission beams or the list of reception beams corresponds to the sensing responders. That is, the beam indication information can indicate a list of transmission beams or a list of reception beams corresponding to each sensing responder. The list of transmission beams corresponding to different sensing responders can be the same or different. The list of reception beams corresponding to different sensing responders can be the same or different. For example, there are at least two sensing responders in the N sensing responders whose directions are different, then the sensing responders with different directions can correspond to different lists of transmission beams or different lists of reception beams.

[0151] The list of transmission beams can be used to indicate the indexes of the transmission beams to be used by the corresponding sensing responders in the sensing measurement session. The list of transmission beams can explicitly indicate the indexes, for example, the list of transmission beams can include one or more indexes of the transmission beams. Alternatively, the list of transmission beams can implicitly indicate the indexes, for example, by using a bitmap to indicate the transmission beams, the transmission beam corresponding to the bit with a value of 1 in the bitmap can be the transmission beam to be used by the corresponding sensing responder, and the transmission beam corresponding to the bit with a value of 0 in the bitmap can be the transmission beam that cannot be used by the corresponding sensing responder. For example, each sensing responder can correspond to a bitmap. The list of reception beams can be used to indicate the indexes of the reception beams to be used by the corresponding sensing responders in the sensing measurement session. Similarly, the list of reception beams can explicitly indicate the indexes, for example, the list of reception beams can include one or more indexes of the reception beams. Alternatively, the list of reception beams can implicitly indicate the indexes. The specific way of indicating the indexes by the list of transmission beams or the list of reception beams is not limited in the embodiments of the present application.

[0152] The index shown in the embodiments of the present application can also be replaced by identification or numbering or other information used to identify the beam, and the embodiments of the present application do not limit this. The embodiments of the present application are exemplified by taking the sending beam list or the receiving beam list, and in specific implementation, the sending beam set or the receiving beam set, or one or more sending beams, one or more receiving beams, etc. can be used to replace this, and the embodiments of the present application do not limit this.

[0153] The above perception measurement session can be a session established by the SBP response end in response to the requirement of the SBP initiation end. Or, the perception measurement session is a session initiated by the SBP response end in combination with the SBP request frame or the SBP response frame. Or, the SBP response end as the perception initiation end can establish the perception measurement session according to the SBP request frame or the SBP response frame. The establishment stage of the perception measurement session, the perception measurement interaction stage, etc. are described above with reference to FIG. 2 or FIG. 3, and will not be described in detail here.

[0154] The above N can be a positive integer. For example, N = 1, or N = 2, or N is greater than 2, etc. will not be listed one by one here.

[0155] The content of the beam indication information is described below.

[0156] The beam indication information can include N1 sending beam lists and N2 receiving beam lists indicated by the SBP initiation end for the SBP response end as the perception initiation end for N perception response ends, N1 is a positive integer less than or equal to N, and N2 is a positive integer less than or equal to N. That is, the SBP initiation end indicates, through the N1 sending beam lists in the beam indication information, the sending beam list respectively indicated by the SBP response end as the perception initiation end for each of the N perception response ends, and indicates, through the N2 receiving beam lists in the beam indication information, the receiving beam list respectively indicated by the SBP response end as the perception initiation end for each of the N perception response ends. The following mode 1 takes N2 = N as an example, mode 2 takes N1 = N as an example, and mode 3 takes N1 = N and N2 = N as an example.

[0157] In a possible implementation, the content of the beam indication information can be as follows:

[0158] Mode 1: The beam indication information includes one sending beam list and N receiving beam lists indicated for N perception response ends, and each receiving beam list corresponds to one perception response end. The N perception response ends can correspond to the same sending beam list.

[0159] For the way 1, the SBP initiator can not only suggest the SBP responder to indicate the transmit beam list and the receive beam list for each of the N sensing responders, but also save the signaling overhead by including one transmit beam list in the beam indication information.

[0160] For the way 2, the SBP initiator can not only suggest the SBP responder to indicate the transmit beam list and the receive beam list for each of the N sensing responders, but also save the signaling overhead by including one receive beam list in the beam indication information.

[0161] For the way 2, the SBP initiator can not only suggest the SBP responder to indicate the transmit beam list and the receive beam list for each of the N sensing responders, but also save the signaling overhead by including one receive beam list in the beam indication information.

[0162] For the way 3, the beam indication information includes N transmit beam lists and N receive beam lists for the N sensing responders, each transmit beam list corresponds to one sensing responder, and each receive beam list corresponds to one sensing responder.

[0163] For the way 3, the beam indication information includes N transmit beam lists and N receive beam lists for the N sensing responders, each transmit beam list corresponds to one sensing responder, and each receive beam list corresponds to one sensing responder.

[0164] For the way 4, the beam indication information includes N transmit beam lists for the N sensing responders, each transmit beam list corresponds to one sensing responder. The N transmit beam lists can also implicitly indicate N receive beam lists. For example, when the sensing responder performs self-sensing and self-receiving, the sensing responder can transmit signals through the transmit beam and receive signals through the same beam.

[0165] Alternatively, the beam indication information includes N receive beam lists for the N sensing responders, each receive beam list corresponds to one sensing responder. The N receive beam lists can implicitly indicate N transmit beam lists.

[0166] As an example, the content of the beam indication information can be defined by a protocol. For example, the content of the beam indication information can be set as the above-mentioned way 3 by default.

[0167] As another example, the content of the beam indication information can correspond to a sensing type. In other words, the content of the beam indication information is associated with a sensing type. In other words, the content of the beam indication information can be determined based on the SBP initiator wanting to sense the sensing type initiated by the sensing initiator proxy. In other words, the content of the beam indication information can be determined based on a role of each of the N sensing responders, which can include at least one of a sensing transmitter or a sensing receiver. The above-mentioned sensing type or the role of the sensing responder is relative to the sensing measurement session, i.e., the role of the sensing responder is the role it plays in the entire sensing measurement session. The role of the sensing responder can be referred to the sensing type shown below or the role bitmap shown below, which will not be described in detail here.

[0168] For example, the sensing type can include self-sensing, transmit-receive split sensing, one-transmit-multiple-receive sensing, or one-receive-multiple-transmit sensing.

[0169] (1) For transmit-receive split sensing:

[0170] Transmit-receive split sensing can be understood as the device that transmits the sensing PPDU and the device that receives the sensing PPDU are not the same device. For transmit-receive split sensing, the sensing responder can be one of a sensing transmitter or a sensing receiver. Thus, one sensing responder can correspond to one transmit beam list and one receive beam list. In other words, each sensing responder has its own transmit beam list and receive beam list. In other words, the transmit beam list and the receive beam list can appear in pairs in the beam indication information. In the case where each of the N sensing responders performs transmit-receive split sensing, the beam indication information can include the transmit beam list and the receive beam list that the SBP initiator suggests for the SBP responder as a sensing initiator, and the SBP responder can indicate the transmit beam list and the receive beam list for each of the N sensing responders.

[0171] FIG. 5a is a schematic diagram of a format of the beam indication information provided by an embodiment of the present application. As shown in FIG. 5a, the beam indication information can sequentially include a transmit beam list 1, a receive beam list 1, a transmit beam list 2, a receive beam list 2, and the like. Among them, the transmit beam list 1 and the receive beam list 1 can correspond to a sensing responder #1 in the N sensing responders, and the transmit beam list 2 and the receive beam list 2 can correspond to a sensing responder #2 in the N sensing responders. FIG. 5a is an example illustrated with the transmit beam list located before the receive beam list, and in a specific implementation, the receive beam list can also be located before the transmit beam list.

[0172] Fig. 5b is another format of the beam indication information according to an embodiment of the present application. As shown in Fig. 5b, the beam indication information can sequentially include a transmitting beam list 1, a transmitting beam list 2, …, a receiving beam list 1, a receiving beam list 2, …, wherein the transmitting beam list 1 can correspond to the sensing response end #1 in the N sensing response ends, the transmitting beam list 2 can correspond to the sensing response end #2 in the N sensing response ends, the receiving beam list 1 can correspond to the sensing response end #1 in the N sensing response ends, and the receiving beam list 2 can correspond to the sensing response end #2 in the N sensing response ends.

[0173] Figs. 5a and 5b exemplarily show the transmitting beam list and the receiving beam list corresponding to two sensing response ends, but should not be understood as a limitation to the embodiments of the present application. As to the transmitting beam list and the receiving beam list, the correspondence between the sensing response ends can refer to the description of the recommended information of the sensing response end shown below, which is not described in detail here.

[0174] (2) For the self-initiating and self-receiving sensing:

[0175] The self-initiating and self-receiving sensing can be understood as that the device transmitting the sensing PPDU and the device receiving the sensing PPDU are the same device. For the self-initiating and self-receiving sensing, the sensing response end can be both the role of the sensing transmitting end and the role of the sensing receiving end. That is, the transmitting beam and the receiving beam used by the sensing response end can be the same. Thus, one sensing response end can correspond to one transmitting beam list, or one sensing response end can correspond to one receiving beam list. In the case that each of the N sensing response ends performs the self-initiating and self-receiving sensing, the beam indication information can include the transmitting beam list that the SBP initiating end indicates for each of the N sensing response ends as the SBP response end as the sensing initiating end, or the beam indication information can include the receiving beam list that the SBP initiating end indicates for each of the N sensing response ends as the SBP response end as the sensing initiating end.

[0176] Fig. 6a is another format of the beam indication information according to an embodiment of the present application. As shown in Fig. 6a, the beam indication information can include a transmitting beam list 1, a transmitting beam list 2, etc. The transmitting beam list 1 can correspond to the sensing response end #1 in the N sensing response ends, and the transmitting beam list 2 can correspond to the sensing response end #2 in the N sensing response ends.

[0177] Fig. 6b is another format of beam indication information according to an embodiment of the present application. As shown in Fig. 6b, the beam indication information can include a receiving beam list 1, a receiving beam list 2, etc. The receiving beam list 1 can correspond to the sensing response end #1 of the N sensing response ends, and the receiving beam list 2 can correspond to the sensing response end #2 of the N sensing response ends.

[0178] In the embodiments of the present application, although the beam indication information includes N sending beam lists, the N sending beam lists can not only indicate the sending beam list corresponding to each of the N sensing response ends, but also implicitly indicate the receiving beam list corresponding to each of the N sensing response ends. Similarly, although the beam indication information includes N receiving beam lists, the N receiving beam lists can not only indicate the receiving beam list corresponding to each of the N sensing response ends, but also implicitly indicate the sending beam list corresponding to each of the N sensing response ends.

[0179] (3) For one-to-many sensing:

[0180] One-to-many sensing can be understood as that one sensing sending end sends a sensing PPDU, and multiple sensing receiving ends receive the sensing PPDU. As an example, for a sensing response end, the sensing response end can be a sensing sending end, and the sensing sending end can send a sensing PPDU to multiple sensing receiving ends. For example, the sensing response end can send the sensing PPDU through a sending beam list, and the multiple sensing receiving ends can respectively use their own receiving beam lists to receive the sensing PPDU. As another example, for a sensing response end, the sensing response end can be one of the multiple sensing receiving ends, and the sensing response end can receive a sensing PPDU. For example, the sensing response end can use its own receiving beam to receive the sensing PPDU.

[0181] Fig. 7a is another format of beam indication information according to an embodiment of the present application. As shown in Fig. 7a, the beam indication information can include a sending beam list, a receiving beam list 1, a receiving beam list 2, etc. That is, each of the N sensing response ends can use the same sending beam list to send a sensing PPDU, or the sensing response ends can use their own receiving beam lists to receive the sensing PPDU. The sending beam list shown in Fig. 7a can also be referred to as a common sending beam list or a shared (or common) sending beam list, etc.

[0182] In the embodiments of the present application, although the beam indication information includes one sending beam list, the sending beam list implicitly indicates the sending beam list corresponding to each of the N sensing response ends.

[0183] (4) For many-to-one sensing:

[0184] One-to-many sensing can be understood as that multiple sensing sending ends send sensing PPDUs, and one sensing receiving end receives the sensing PPDUs. As an example, for a sensing responding end, the sensing responding end can be a sensing receiving end, for example, the sensing responding end can receive the sensing PPDUs by using the same receiving beam list. As another example, for a sensing responding end, the sensing responding end can be one of the multiple sensing sending ends, and the sensing responding end can send the sensing PPDUs by using its own sending beam list.

[0185] FIG. 7b is another format of beam indication information provided by the embodiments of the present application. As shown in FIG. 7b, the beam indication information can include a receiving beam list, a sending beam list 1, a sending beam list 2, and the like. That is, each of the N sensing responding ends can send the sensing PPDUs by using its own sending beam list, or the sensing responding ends can receive the sensing PPDUs by using the same receiving beam list. The receiving beam list shown in FIG. 7b can also be referred to as a common receiving beam list or a shared (or common) receiving beam list, and the like.

[0186] In the embodiments of the present application, although the beam indication information includes one receiving beam list, the beam indication information implicitly indicates the receiving beam list corresponding to each of the N sensing responding ends.

[0187] The position of the sending beam list shown in FIG. 7a and the position of the receiving beam list shown in FIG. 7b are illustrated by taking the first word element in the beam indication information as an example. In a specific implementation, the sending beam list shown in FIG. 7a and the receiving beam list shown in FIG. 7b can also be located in the last sub-element in the beam indication information, or in other special positions, and the embodiments of the present application are not limited thereto.

[0188] In the embodiments of the present application, the SBP initiating end sets the content of the beam indication information in combination with the sensing type, so that the content of the beam indication information is more matched with the sensing type.

[0189] As a possible implementation, the sensing types corresponding to the N sensing responding ends are the same. At this time, the content of the beam indication information can refer to FIG. 5a, FIG. 5b, FIG. 6a, FIG. 6b, FIG. 7a or FIG. 7b, and the like.

[0190] As another possible implementation, the perception types corresponding to at least two of the N perception response ends are different. At this time, the beam indication information can indicate a transmission beam list or a reception beam list for each of the N perception response ends. The content of the beam indication information can be set according to the perception type corresponding to FIG. 5a, FIG. 5b, FIG. 6a, FIG. 6b, FIG. 7a or FIG. 7b. For example, N1 can be less than N, or N2 can be less than N. When N1 is less than N, the transmission beam lists of at least two of the N perception response ends are the same. When N2 is less than N, the reception beam lists of at least two of the N perception response ends are the same. Or, when N1 is less than N or N2 is less than N, the perception types of at least two of the N perception response ends are different. For example, the N perception response ends have at least two of the following in the current perception measurement session: some perception response ends have a perception type of transceiving distributed perception, some perception response ends have a perception type of self-transmitting and self-receiving perception, some perception response ends have a perception type of one-transmitting and multiple-receiving perception, and some perception response ends have a perception type of one-receiving and multiple-transmitting perception. The current perception measurement session can be a perception measurement session established by the SBP response end at the request of the SBP initiator. The specific content of the beam indication information is not repeated here.

[0191] For example, the beam indication information can be carried in the optional sub-element field of the SBP request frame. The number of bits occupied by the optional sub-element field is not limited in the embodiments of the present application. Similarly, the field carried by the beam indication information is also not limited in the embodiments of the present application.

[0192] In the embodiments of the present application, the SBP initiator can indicate a transmission beam list or a reception beam list for different perception response ends, so that different perception response ends can use different transmission beam lists to transmit signals, or different perception response ends can use different reception beam lists to receive signals. Therefore, the SBP initiator can assign a transmission beam list or a reception beam list in combination with the direction of the perception response end, thereby improving the flexibility of beam assignment and improving the perception performance.

[0193] (II) Information of recommended perception response end

[0194] In a possible implementation, the SBP request frame includes recommended perception responder information, and the N perception responders are included in the recommended perception responder information. The recommended perception responder information can be used to indicate the perception responders recommended (or suggested) by the SBP initiator for the SBP responders. For ease of description, the M perception responders are used to represent the perception responders indicated in the recommended perception responder information below. M is a positive integer. As M can be a positive integer greater than or equal to N.

[0195] As an example, M = N, and the M perception responders are the same as the N perception responders. For example, the order of the N perception responders in the recommended perception responder information can correspond to the order of the perception responders corresponding to the transmission beam list indicated by the beam indication information, or correspond to the order of the perception responders corresponding to the reception beam list indicated by the beam indication information.

[0196] For example, the transmission beam list 1 and the reception beam list 1 in FIG. 5a can correspond to the first perception responder indicated in the recommended perception responder information. The transmission beam list 2 and the reception beam list 2 in FIG. 5a can correspond to the second perception responder indicated in the recommended perception responder information. The same applies to the subsequent ones, which are not listed here.

[0197] The beam indication information in the SBP request frame can be located after the recommended perception responder information. In this way, the SBP responder can learn the perception responders corresponding to the subsequent transmission beam list or reception beam list in the SBP request frame by parsing the recommended perception responder information, thereby improving the parsing efficiency.

[0198] As another example, M > N, and the N perception responders are included in the M perception responders. For example, the N perception responders can be sequentially located in the first N of the recommended perception responder information. For example, the N perception responders are the first N of the M perception responders by default.

[0199] For example, M=5, i.e., the recommended perception responder information indicates five perception responders, which are the first perception responder to the fifth perception responder in sequence. N=3. For example, the sending beam list 1 and the receiving beam list 1 in FIG. 5a correspond to the first perception responder indicated in the recommended perception responder information. The sending beam list 2 and the receiving beam list 2 in FIG. 5a correspond to the second perception responder indicated in the recommended perception responder information. The sending beam list 3 (not shown in FIG. 5a) and the receiving beam list 3 (not shown in FIG. 5a) in FIG. 5a correspond to the third perception responder indicated in the recommended perception responder information. The fourth perception responder and the fifth perception responder are not indicated in the beam indication information.

[0200] The correspondence (or sequence) between the N perception responders and the M perception responders shown above is only an example and should not be construed as a limitation on the embodiments of the present application. For example, the perception responders corresponding to the sending beam list or the receiving beam list indicated in the beam indication information can also be located at a fixed position in the recommended perception responder information. The value of N can have a correspondence with the fixed position. For example, when N=2, the two perception responders can be the first perception responder and the second perception responder in the recommended perception responder information (or the M perception responders).

[0201] For example, the recommended perception responder information can include at least one of the following: an identifier (ID) of the recommended perception responder, a medium access control (MAC) address of the recommended perception responder, or an IP address of the recommended perception responder. The information listed above for identifying different perception responders is only an example and should not be construed as a limitation on the embodiments of the present application.

[0202] For example, the information of the recommended sensing responder can be carried in a sensing responder address field or a sensing responder ID field of the SBP request frame. When the SBP request frame includes both the sensing responder address field and the sensing responder ID field, the sensing responders carried in the two fields are the same. The order of the sensing responders carried in the two fields can also be the same. The field in which the information of the recommended sensing responder is carried is not limited in the embodiments of the present application. The number of bits occupied by each field is not limited in the embodiments of the present application. Of course, the information of the recommended sensing responder can not include the sensing responder ID field, for example, the sensing responder ID field can be carried in the SBP response frame.

[0203] For example, the information of the recommended sensing responder is carried in the sensing responder address field, the sensing responder address field can carry MAC addresses of M sensing responders. For example, the sensing responder address field can sequentially carry the MAC address of each of the M sensing responders. The description of the sensing responder address field herein also applies to the sensing responder ID field, which will not be described herein again.

[0204] In the embodiments of the present application, the SBP request frame includes the information of the recommended sensing responder, so that the SBP responder can clearly know which sensing responders correspond to the transmission beam list or the reception beam list indicated by the beam indication information.

[0205] (Three), role bitmap

[0206] In a possible implementation, the SBP request frame includes a role bitmap, which is used to indicate the role of each of the N sensing responders, and the role of the sensing responder is at least one of a sensing transmitter or a sensing receiver. Alternatively, the role bitmap is used to indicate the role of each of the M sensing responders. The M sensing responders include the N sensing responders.

[0207] As an example, the role bitmap can occupy 2N bits. That is, each sensing responder can correspond to 2 bits. The first bit of the 2 bits can be used to indicate whether the sensing responder is a sensing transmitter, and the second bit of the 2 bits can be used to indicate whether the sensing responder is a sensing receiver. For example, when the values of the 2 bits are both 2, it indicates that the sensing responder can be both a sensing transmitter and a sensing receiver in a sensing measurement session, that is, the sensing responder can perform transmit-receive-disposed sensing. For another example, when the values of the 2 bits are both 0, it indicates that the sensing responder can be both a sensing transmitter and a sensing receiver in the same sensing measurement session, that is, the sensing responder can perform self-transmit-self-receive sensing. The order of the sensing responders corresponding to each 2 bits in the role bitmap can be the same as the order of the N sensing responders shown above.

[0208] As another example, the role bitmap can occupy 3N bits. That is, each sensing responder can correspond to 3 bits. The first bit of the 3 bits can be used to indicate whether the sensing responder is a sensing transmitter, the second bit of the 3 bits can be used to indicate whether the sensing responder is a sensing receiver, and the third bit of the 3 bits can be used to indicate whether the sensing responder can perform self-transmit-self-receive sensing. The order of the sensing responders corresponding to each 3 bits in the role bitmap can be the same as the order of the N sensing responders shown above.

[0209] Optionally, to explicitly indicate the sensing type, the SBP request frame can include sensing type indication information, which can be used to indicate the sensing type. The SBP request frame can include at least one of the role bitmap or the sensing type indication information. The specific form of the sensing type indication information is not described in detail in the embodiments of the present application.

[0210] It can be understood that the above is described by taking N as an example. The above N can be replaced by M, which is not described in detail here.

[0211] The role bitmap can also be referred to as a sensing responder role bitmap, and the name of the role bitmap is not limited in the embodiments of the present application.

[0212] In the embodiments of the present application, the SBP request frame includes the role bitmap, so that the SBP responder can know whether the content indicated by the beam indication information is the above-mentioned mode 1, mode 2 or mode 3, etc. based on the role bitmap.

[0213] (Four) Beam list number

[0214] As a possible implementation, the SBP request frame can not include the beam list number. The number of sensing responding ends indicated in the information of the recommended responding end in the SBP request frame can correspond to the number of beam list pairs. For example, the number of beam list pairs = M. That is, N = M.

[0215] As another possible implementation, the SBP request frame includes a beam list number, which is used to indicate the number of beam list pairs of the transmission beam list and the reception beam list. The beam list number can indicate the number of beam list pairs, or implicitly indicate the value of N. The beam list number can also implicitly indicate whether the beam indication information is included in the SBP request frame. For example, when the beam list number is 0, it indicates that the SBP request frame does not include (or does not exist or does not appear) beam indication information. When the beam list number is greater than 0, it indicates that the SBP request frame includes (or exists or appears) beam indication information.

[0216] As an example, for the transceiver-disposition sensing, the transmission beam list and the reception beam list appear in pairs, and the transmission beam list and the reception beam list corresponding to one sensing responding end can be referred to as a beam list pair (or a beam list group, etc.). The beam list number indicates the number of beam list pairs.

[0217] As another example, for the self-transmission and self-reception sensing, one sensing responding end can correspond to one transmission beam list, and the beam list number can indicate the number of transmission beam lists. Since the transmission beam list can also be used for receiving signals, the number of transmission beam lists can also be referred to as the number of beam list pairs. Similarly, one sensing responding end can also correspond to one reception beam list, and the beam list number can indicate the number of reception beam lists.

[0218] As another example, for the one-transmission and multiple-reception sensing, or the one-reception and multiple-transmission sensing, N sensing responding ends can correspond to one transmission beam list and N reception beam lists, and the beam list number can indicate the number of reception beam lists. Alternatively, N sensing responding ends can correspond to one reception beam list and N transmission beam lists, and the beam list number can indicate the number of transmission beam lists.

[0219] In the embodiments of the present application, by including the beam list number, the SBP responding end can effectively know how many sensing responding ends are recommended in the SBP request frame based on the beam list number.

[0220] (Five), beam list exists

[0221] The SBP request frame includes a beam list presence, which can be used to indicate whether the beam indication information exists in the SBP request frame. When the beam list presence is set to 1, it can be indicated that the beam indication information exists in the SBP request frame, or the beam indication information appears in the SBP request frame, or the beam indication information is carried in the SBP request frame. When the beam list presence is set to 0, it can be indicated that the beam indication information does not exist in the SBP request frame, or the beam indication information does not appear in the SBP request frame, or the beam indication information is not carried in the SBP request frame.

[0222] In the case that the SBP request frame includes the beam list presence, as a possible implementation manner, the SBP request frame can be set to N perception response ends respectively indicating the transmission beam list or the reception beam list by default. For example, N = M, or N = M-1, or N = M-2, etc. Alternatively, the protocol predefines the value of N or the position of N perception response ends in M perception response ends, etc. The specific value of N is not limited in the embodiments of the present application. As another possible implementation manner, the SBP request frame can include a beam list number field.

[0223] The beam list presence can also be referred to as beam list appearance or beam list carrying, etc. The name of the beam list presence is not limited in the embodiments of the present application.

[0224] In the embodiments of the present application, the SBP request frame includes the beam list presence, so that the SBP response end can effectively know whether the SBP request frame includes the beam indication information.

[0225] Further, the SBP request frame can further include at least one of the following: the number of perception response ends (see (c) below), the number of perception response ends is mandatory (see (d) below), the recommended number of perception response ends (see (e) below), the recommended perception response end list presence (see (f) below), the recommended response end is mandatory (see (g) below), the SBP procedure expiration index (i), the perception response end to perception response end SR2SR probe request. The description of each field can be referred to below, which is not described in detail here.

[0226] The name or the number of bits occupied of each field shown in the present application, or the relationship between the bits and the meanings should not be understood as a limitation on the embodiments of the present application.

[0227] As an example, the SBP request frame can have different names when the SBP request frame is transmitted in different frequency bands. For example, the SBP request frame can be referred to as a DMG SBP request frame when the SBP request frame is transmitted in a frequency band involved in DMG. For another example, the SBP request frame can be referred to as a MMW or IMMW SBP request frame when the SBP request frame is transmitted in a frequency band involved in MMW or IMMW.

[0228] As another example, the SBP request frame can have the same name when the SBP request frame is transmitted in different frequency bands. The SBP request frame is transmitted in a frequency band involved in a sensing measurement session corresponding to a SBP procedure initiated by the SBP request frame.

[0229] Embodiments of the present application do not limit the specific format of the SBP request frame or the applicable scenario. As shown above, each piece of information can be carried in a first element in the SBP request frame. Alternatively, part of the above-mentioned information is carried in the first element, and the other part is carried in a second element in the SBP request frame. Embodiments of the present application do not limit whether each piece of information shown above is carried in the same element in the SBP request frame. Embodiments of the present application also do not limit the element name in which each piece of information is carried. The description of the SBP request frame is also applicable to Examples 1-3 below, which will not be described again.

[0230] The specific format of the SBP request frame is described below in combination with the information shown above.

[0231] Example 1,

[0232] Each piece of information shown above can be carried in a first element, which can be referred to as an SBP parameter element. For another example, the first element can be referred to as an IMMW SBP parameter element. For another example, the first element can be referred to as an IMMW sensing measurement parameter element. That is, each piece of information shown below can be included in the relevant parameters of the sensing measurement session initiated by the SBP response end recommended by the SBP initiating end to the SBP response end. Alternatively, each piece of information shown below can also be included in the sensing parameters of the sensing response end performing the sensing measurement session allocated by the SBP response end to the sensing response end recommended by the SBP initiating end to the SBP response end. For ease of description, the IMMW SBP parameter element is taken as an example for description below. The SBP request frame can be referred to as an IMMW SBP request frame.

[0233] As an example, the IMMW SBP parameters element can be used to initiate an IMMW SBP procedure. The IMMW SBP parameters element can be carried in an IMMW SBP request frame. As another example, the IMMW SBP parameters element can be carried in a sub-7 GHz SBP request frame.

[0234] As another example, the IMMW SBP parameters element can be used to initiate a sub-7 GHz SBP procedure. The IMMW SBP parameters element can be carried in a sub-7 GHz SBP request frame.

[0235] That is, the IMMW SBP parameters element shown in embodiments of the present application can be used to initiate an IMMW SBP procedure or a sub-7 GHz SBP procedure. The description of the IMMW SBP procedure or the sub-7 GHz SBP procedure can be referred to the above, such as FIG. 3, and will not be described in detail here. The other elements or fields included in the SBP request frame carried by the IMMW SBP parameters element are not limited in embodiments of the present application.

[0236] FIG. 8a is a format diagram of the IMMW SBP parameters element according to an embodiment of the present application. As shown in FIG. 8a, the IMMW SBP parameters element can include at least one of the following: element ID, length, element ID extension, IMMW SBP parameters control, sensing responder address, sensing responder IDs, or optional subelements (or sensing subelements). The number of bytes occupied by each field can be as shown in FIG. 8a, which will not be described here in detail. The number of bytes shown in FIG. 8a is only an example and should not be construed as a limitation on embodiments of the present application. It can be understood that the names of each field or element or the number of bytes or bits occupied by each field or element shown in the present application are only examples and should not be construed as a limitation on the present application. The order of each field shown in the present application is only an example and should not be construed as a limitation on the present application.

[0237] The element ID field and the element ID extension field can be used to identify the IMMW SBP parameters element. The length field can be used to indicate the length of the IMMW SBP parameters element.

[0238] The IMMW SBP parameter control field can include the relevant parameters that the SBP initiator suggests for the SBP responder to initiate a sensing measurement session. The IMMW SBP parameter control field can include at least one of the following: IMMW SBP request, sensing responder, IMMW number of sensing responders, IMMW mandatory number of responders, IMMW number of preferred responders, IMMW preferred responder list, IMMW mandatory preferred responder, number of beam lists. The order, name or bit number of each field shown in FIG. 8a is only an example and should not be construed as a limitation to the embodiments of the present application.

[0239] (a) IMMW SBP request field: This field can be used to distinguish whether the IMMW SBP parameter element is in the IMMW SBP request frame or the IMMW SBP response frame. If the IMMW SBP parameter element is in the IMMW SBP request frame, the field is 1. If the IMMW SBP parameter element is in the IMMW SBP response frame, the field is 0.

[0240] (b) Sensing responder field: This field is 1 when the SBP initiator participates in the sensing measurement session (also referred to as the current sensing measurement session) initiated by the SBP responder proxy, i.e. the SBP initiator participates in the sensing measurement session initiated by the SBP responder proxy as a sensing responder. This field is 0 when the SBP initiator does not participate in the current sensing measurement session. In other words, the sensing responder field can be used to indicate whether the SBP initiator wants to participate in the subsequent sensing measurement session as a sensing responder, which is initiated by the SBP responder in response to the IMMW SBP request frame (or IMMW SBP response frame) sent by the SBP initiator.

[0241] (c) IMMW-aware responder number field: This field can be used to indicate the number (or number of, or quantity of, etc.) of aware responders (or IMMW-aware responders) participating in the SBP measurement session. Alternatively, this field can represent the number of aware responders requested (or suggested or recommended) by the SBP initiator for the SBP responder proxy to initiate the SBP measurement session. When the aware responder field indicates that the SBP initiator is participating in the subsequent SBP measurement session as an aware responder, or in other words, the aware responder value field is 1, the number indicated by the IMMW-aware responder number field includes the SBP initiator.

[0242] (d) IMMW-aware responder number mandatory field: This field can be used to indicate whether the IMMW-aware responder number field is mandatory. Alternatively, this field can be used to indicate whether the number of aware responders indicated by the IMMW-aware responder number field is mandatory. Illustratively, when the field is 1, it indicates that the IMMW-aware responder number is mandatory. When the number of aware responders participating in the SBP measurement session as SBP responders / aware initiators does not match the number of aware responders indicated by the IMMW-aware responder number field, the AP cannot successfully establish the SBP measurement session. That is, the SBP measurement session established by the AP does not meet the requirements of the SBP request frame, and the AP can close the SBP procedure by sending an IMMW SBP close frame. Illustratively, when the field is 0, it indicates that the number of aware responders participating in the SBP measurement session can be less than or equal to the number indicated by the IMMW-aware responder number field.

[0243] (e) IMMW-recommended responder number field: This field can indicate the number of recommended aware responders (or preferred aware responders) suggested by the SBP initiator. Similar to the IMMW-aware responder number field, when the aware responder field indicates that the SBP initiator is participating in the subsequent SBP measurement session as an aware responder, or in other words, the aware responder value field is 1, the number indicated by the IMMW-recommended responder number field includes the SBP initiator.

[0244] (f) IMMW recommended responder list field: This field can be used to indicate whether a list of recommended (or preferred) sensing responder is carried in the IMMW SBP parameter element. If this field is 1, it means that a list of recommended / preferred sensing responder is carried in the IMMW SBP parameter element. If this field is 0, it means that no list of recommended / preferred sensing responder is carried in the IMMW SBP parameter element. When this field is 1, the MAC addresses of the recommended / preferred sensing responder can be carried in the sensing responder address field, and the number of recommended sensing responder can be indicated by the IMMW recommended responder number field. Similarly, when the sensing responder field indicates that the SBP initiator is to participate in the subsequent sensing measurement session as a sensing responder, or in other words, the sensing responder number field is 1, the sensing responder address field includes the MAC address of the SBP initiator. Exemplarily, this field can also be referred to as recommended sensing responder list present field.

[0245] (g) IMMW recommended responder mandatory field: This field indicates whether the list of recommended / preferred sensing responder provided by the SBP initiator is mandatory. If this field is 1, it means that the list of recommended / preferred sensing responder is mandatory, and the SBP responder (e.g., an AP) cannot select a sensing responder other than the recommended sensing responder list when establishing a sensing measurement session. If this field is 0, it means that the list of recommended / preferred sensing responder is optional, and the SBP responder (e.g., an AP) can select a sensing responder other than the recommended sensing responder list when establishing a sensing measurement session.

[0246] (h) Beam pair number field: This field indicates how many transmit beam lists or how many receive beam lists are included in the IMMW SBP parameter element.

[0247] As an example, the value indicated by the beam pair number field is the same as the value indicated by the IMMW recommended responder number field. That is, M = N.

[0248] As another example, the value indicated by the beam pair number field is less than the value indicated by the IMMW recommended responder number field. That is, N < M.

[0249] The description of the beam pair number field can be referred to the above (iv), and will not be described in detail here.

[0250] Optionally, the IMMW SBP parameter control field can further include an IMMW SBP procedure expiration index field or an SR2SR probe request indication field.

[0251] (i) IMMW SBP procedure expiry index field (not shown in Fig. 8a or Fig. 8b): This field can contain an unsigned integer indicating a time duration. After the AP monitors the channel and finds no frames (e.g., frames related to the sensing measurement session) within the agreed time window, it starts counting down the time duration indicated by this field. When the counting down ends, if there is still no frame interaction in the channel, the AP can consider that the current sensing measurement session procedure ends. For example, the value of this field can be 2procedure expiry exponent+8 ms, where the value of the parameter procedure expiry exponent is equal to the time duration indicated by the IMMW SBP procedure expiry index field.

[0252] In the embodiments of the present application, when the IMMW recommended responder list field is 1, the IMMW SBP request frame can carry a recommended sensing responder list, and the SBP initiator can assign sensing beams to these recommended sensing responders through the optional sub-element field. That is, the optional sub-element field can carry the beam indication information shown above.

[0253] As shown in example 1 in Fig. 8a, for transceiver-separated sensing, every two beam list sub-elements (i.e., a transmit beam list sub-element and a receive beam list sub-element) can correspond to one recommended sensing responder. The sensing responders corresponding to every two beam list sub-elements in the optional sub-element field can one-to-one correspond to the sensing responders corresponding to the MAC addresses in the sensing responder address field. The order of the transmit beam list and the receive beam list shown in example 1 is only an example, and every two beam list sub-elements can also include the receive beam list and the transmit beam list of the corresponding sensing responder in turn. As shown in example 2 in Fig. 8a, for transceiver-separated sensing, the optional sub-element field can include the transmit beam list of each sensing responder in turn, and include the receive beam list of each sensing responder in turn. Alternatively, the optional sub-element field can include the receive beam list of each sensing responder in turn, and include the transmit beam list of each sensing responder in turn.

[0254] As shown in example 3 in Fig. 8a, for self-transmitting and self-receiving sensing, the optional sub-element field can include the transmit beam list (or the receive beam list) of each sensing responder in turn.

[0255] As shown in example 4 in Fig. 8a, for one-transmitting and multiple-receiving sensing or one-receiving and multiple-transmitting sensing, the optional sub-element field can include the transmit beam list of each sensing responder in turn, and include one common receive beam list of N sensing responders. Alternatively, the optional sub-element field can include the receive beam list of each sensing responder in turn, and include one common transmit beam list of the N sensing responders.

[0256] The description of the example 1 to example 4 in FIG. 8a can also refer to the above description of the beam indication information or the number of beam lists, and the like, and will not be described in detail herein.

[0257] FIG. 8a is described with M=N, that is, the SBP initiator can assign a sensing beam for each recommended responder (that is, the responder indicated by the responder address field). As described above, M can also be greater than N, that is, the SBP initiator can assign a sensing beam for part of the M responders indicated by the responder address field. The format of the optional sub-element field or the IMMW SBP parameter element when M>N will not be described in detail herein.

[0258] FIG. 8b is another format of the IMMW SBP parameter element provided by the embodiments of the present application. As shown in FIG. 8b, the IMMW SBP parameter control field in the IMMW SBP parameter element can include a preferred responder beam list present field. The description of other fields or elements in the IMMW SBP parameter element can refer to FIG. 8a, and will not be described in detail herein. The description of the preferred responder beam list present field can refer to the description of (v) above, and will not be described in detail herein.

[0259] When the preferred responder beam list present field is 1, the responders corresponding to the transmission beam list or the reception beam list indicated by the optional sub-element field can one-to-one correspond to the responders indicated by the responder address field; or, the responders corresponding to the transmission beam list or the reception beam list indicated by the optional sub-element field can be part of the responders indicated by the responder address field. The description of the responder address field and the optional sub-element field can refer to the description of M and N above, and will not be described in detail herein.

[0260] For example, the IMMW SBP parameter element can also include the beam list number field and the preferred responder beam list present field. This will not be described in detail herein.

[0261] FIGS. 8a and 8b are examples in which the SBP request frame is the IMMW SBP request frame, and the above information is included in the IMMW SBP parameter element.

[0262] In the embodiments of the present application, the independent IMMW SBP parameter element is designed, so that the IMMW SBP parameter element is more independent and concise.

[0263] In the embodiments of the present application, the IMMW SBP parameter element shown in FIG. 8a and FIG. 8b is exemplified by taking the SBP initiator as an example to recommend the SBP responder to respectively indicate the transmit beam list or the receive beam list for N sensing responders. In a specific implementation, for the IMMW SBP parameter element shown in FIG. 8a or FIG. 8b, the SBP initiator can also recommend a unified transmit beam list or a unified receive beam list for the N sensing responders. That is, the transmit beam list of the N sensing responders can be the same, and the receive beam list of the N sensing responders can be the same.

[0264] Example two,

[0265] The various information shown above can be carried in a first element, which can be referred to as an SBP parameter element.

[0266] As an example, the SBP parameter element can be used to initiate a sub-7GHz SBP procedure. For example, the SBP parameter element can be carried in a sub-7GHz SBP request frame (or an IMMW SBP request frame, etc.), and the SBP parameter element is carried in the sub-7GHz SBP request frame together with a sensing measurement parameter element. When the SBP initiator initiates a sub-7GHz SBP procedure, the SBP initiator can carry the sensing measurement parameter element and the SBP parameter element in the SBP request frame. Under sub-7GHz, since the signal is omnidirectionally transmitted, the SBP initiator can not need to assign the transmit beam list or the receive beam list to the recommended sensing responder. At this time, the beam list number field can be set to 0, or the recommended responder beam list present field can be set to 0. In addition, the optional sub-element field in the SBP request frame does not carry the transmit beam list and the receive beam list.

[0267] As another example, the SBP parameter element can be used to initiate a DMG SBP procedure. For example, the SBP parameter element can be carried in a DMG SBP request frame (or a sub-7GHz SBP request frame, etc.), and the SBP parameter element is carried in the DMG SBP request frame together with a DMG sensing measurement parameter element.

[0268] As another example, the SBP parameter element can be used to initiate an IMMW SBP procedure. The SBP parameter element can be carried in an MMW SBP request frame or an IMMW SBP request frame (or a sub-7GHz SBP request frame, etc.). The SBP parameter element is carried in an MMW (or IMMW) SBP request frame with an MMW (or IMMW) sensing measurement parameter element. In a DMG-involved frequency band or an IMMW-involved frequency band or an MMW-involved frequency band, since the signal is transmitted directionally, the SBP initiator can assign a transmit beam list or a receive beam list to the recommended sensing responder. At this time, the SR2SR request field shown below can be a reserved field.

[0269] That is, the SBP parameter element shown in Example Two can be carried with a sensing measurement parameter element (only an example) in a frame to complete an SBP request in a sub-7GHz frequency band, or can be carried with an IMMW (or MMW, etc.) sensing measurement parameter element (only an example) in a frame to complete an SBP request in a millimeter wave frequency band.

[0270] FIG. 9a is a format diagram of an SBP parameter element according to an embodiment of the present application. As shown in FIG. 9a, the SBP parameter element can include at least one of the following: an element ID, a length, an element ID extension, an SBP parameter control, a sensing responder address, sensing responder IDs, a sensing responder role bitmap, or optional sub-elements.

[0271] The SBP parameter control field can include at least one of the following: SBP request, SBP procedure expiry exponent, sensing responder, number of sensing responders, mandatory number of responders, preferred responder list, number of preferred responders, mandatory preferred responder, SR2SR sounding request, preferred responder role bitmap represent, or number of beam lists.

[0272] The SBP request field, SBP procedure expiry exponent field, sensing responder field, number of sensing responders field, mandatory number of responders field, preferred responder list field, number of preferred responders field, mandatory preferred responder field, and number of beam lists field can refer to the above description, and will not be described in detail here.

[0273] The preferred responder role bitmap represent field can be used to indicate whether the sensing responder role bitmap field exists in the SBP parameter element. If the field is 1, it means that the SBP parameter element has the sensing responder role bitmap field, or the SBP parameter element will have the sensing responder role bitmap field, or the SBP parameter element carries the sensing responder role bitmap field. If the field is 0, it means that the SBP parameter element does not have the sensing responder role bitmap field, or the SBP parameter element will not have the sensing responder role bitmap field, or the SBP parameter element does not carry the sensing responder role bitmap field.

[0274] The SR2SR sounding request field can be used to indicate that the SBP responder initiates an SR2SR sensing measurement.

[0275] FIG. 9b is another format of the SBP parameter element provided by the embodiments of the present application. The description of FIG. 9b can refer to FIG. 9a or FIG. 8a or the above description of various information, and will not be described in detail here.

[0276] Comparing example one and example two, it can be found that the IMMW SBP parameter element shown in example one and the SBP parameter element structure shown in example two have high similarity. Thus, the SBP parameter element shown in example two can be not only suitable for the sensing of sub-7GHz, but also suitable for the sensing of DMG, and suitable for the sensing of MMW or IMMW. Thus, the SBP parameter element is designed uniformly, which is simple and efficient, and can make the SBP response end obtain different information based on different contents of one frame format, and has high multiplexing efficiency.

[0277] Example three,

[0278] The various information shown above can be carried in a first element, which can be referred to as a DMG SBP parameter element.

As shown in FIG. 10a, the DMG SBP parameter element can include at least one of the following: element ID, length, element ID extension, DMG SBP parameter control, sensing responder address, sensing responder ID, or optional subelement.

[0280] The DMG SBP parameter control field can include at least one of the following: DMG SBP request, sensing responder, DMG number of sensing responders, DMG mandatory number of responders, DMG number of preferred responders, DMG preferred responder list, DMG mandatory preferred responder, and number of beam lists.

[0283] The DMG SBP parameter element and the DMG sensing measurement session element can be sent through a DMG SBP request frame, so as to initiate a DMG SBP procedure. Alternatively, the DMG SBP parameter element can be carried in a SBP request frame in a sensing procedure in the sub-7GHz, or can be carried in an IMMW SBP request frame in a sensing procedure in the IMMW. Thus, the DMG SBP procedure is initiated through the SBP request frame or the IMMW SBP request. The description of the DMG SBP parameter element in Example Three can refer to the description of the SBP parameter element in Example One or Example Two shown above, and will not be repeated here.

[0284] In the embodiments of the present application, the sensing scenario of the DMG SBP is optimized, so that the DMG SBP initiator can allocate a beam list for the DMG sensing responder, improve the flexibility of beam allocation, and improve the sensing performance.

The transceiver is configured to communicate with other devices / apparatuses via a transmission medium.

[0309] Optionally, the apparatus 120 can further include one or more memories 1230 configured to store program instructions and / or data. The memory 1230 is coupled to the processor 1220.

The processor 1220 can operate in cooperation with the memory 1230. The processor 1220 can execute the program instructions stored in the memory 1230. Optionally, at least one of the one or more memories can be included in the processor.

[0310] The specific connection medium between the transceiver 1210, the processor 1220 and the memory 1230 in the embodiments of the present application is not limited. In FIG. 12, the memory 1230, the processor 1220 and the transceiver 1210 are connected through a bus 1240, which is represented by a thick line in FIG. 12, and the connection mode between other components is only schematically illustrated and is not limited. The bus can be divided into an address bus, a data bus, a control bus, etc. For convenience of representation, only one thick line is used in FIG. 12, but it does not mean that there is only one bus or only one type of bus.

The general processor can be a microprocessor or any conventional processor, etc. The steps of the method disclosed in combination with the embodiments of the present application can be directly embodied as execution completed by a hardware processor, or executed by a combination of hardware and software modules in the processor, etc.

[0314] When the apparatus is powered on, the processor 1220 can read a software program in the memory 1230, interpret and execute instructions of the software program, and process data of the software program. When data needs to be sent wirelessly, the processor 1220 outputs a baseband signal to the radio frequency circuit after baseband processing on the data to be sent, and the radio frequency circuit converts the baseband signal into a radio frequency signal and sends the radio frequency signal in the form of an electromagnetic wave to the outside through an antenna.
