Description

Technical Field

[0001] Embodiments of the present application are related to the communication field, and more specifically, to an information indication method and a communication device.

Background Art

[0002] Signals transmitted by a Wireless Fidelity (Wi-Fi) system device are generally received by another device after being reflected, diffracted, and scattered by various obstacles. Therefore, the signals received by another device are usually obtained by superimposing a plurality of signals. This makes it easy for the wireless signal to sense the physical environment through which it passes. Also, sensing technology has been derived from this.

[0003] In sensing technology, a sensing transmitting end transmits a Physical Protocol Data Unit (PPDU) used for sensing measurement in the sensing process, that is, a sensing PPDU. A sensing receiving end receives the sensing PPDU and performs sensing measurement in the sensing process.

[0004] Regarding devices in a communication system, how to determine that a received PPDU is a sensing PPDU is an urgent issue to be solved.

Summary of the Invention

[0005] Embodiments of the present application provide an information indication method and a communication device to distinguish between a sensing PPDU and a non-sensing PPDU in a communication system.

[0006] According to a first aspect, an information indication method is provided. The method may be executed by a transmitting end device, or may be executed by a chip or circuit configured in the transmitting end device. This is not limited in the present application.

[0007] The method includes generating a PPDU, which contains sensing instruction information indicating that the PPDU is a PPDU to be used for sensing measurements, and that the PPDU is a directional multi-gigabit (DMG) single-carrier (SC) mode PPDU, an enhanced directional multi-gigabit (EDMG) single-carrier mode PPDU, or an EDMG orthogonal frequency division multiplexing (OFDM) mode PPDU, and transmitting the PPDU.

[0008] According to the solution in this embodiment of the present application, the PPDU generated by the transmitting end includes sensing instruction information, which may indicate that the PPDU is a PPDU to be used for sensing measurements. The receiving end may determine, based on the sensing instruction information, that the PPDU is a PPDU to be used for sensing measurements. The receiving end does not determine a PPDU that does not include sensing instruction information as a sensing PPDU. In this way, sensing PPDUs and non-sensing PPDUs can be distinguished in the communication system.

[0009] Furthermore, once a PPDU is determined to be the one used for sensing measurements, the receiving end does not need to listen on the channel. This helps to use communication resources more efficiently.

[0010] Referring to the first aspect, in some implementations of the first aspect, the PPDU is a DMG single-carrier mode PPDU, which includes a DMG header field, and the additional PPDU (A-PPDU) indicator field and the training length indicator field within the DMG header field carry sensing indicator information.

[0011] Therefore, in this embodiment of the present application, the current instruction field can be reused, and the instruction of the sensing PPDU is implemented without introducing a new instruction field, thus helping to save resources.

[0012] Furthermore, the solution presented in this application is compatible with current protocols and can offer better scalability.

[0013] Referring to the first aspect, in some implementations of the first aspect, the additional PPDU instruction field is field B30 in the DMG header field, and the training length instruction fields are fields B32 through B36 in the DMG header field.

[0015] Therefore, in this embodiment of the present application, the current instruction field can be reused, and the instruction of the sensing PPDU is implemented without introducing a new instruction field, thus helping to save resources.

[0016] Furthermore, since the A-PPDU instruction field in the DMG header is used for both DMG PPDU and EDMG PPDU, the sensing instruction fields in the DMG PPDU and EDMG PPDU can be integrated, thereby reducing implementation complexity.

[0017] Referring to the first aspect, in some implementations of the first aspect, the additional PPDU instruction field is the B30 field within the L-header field.

[0025] Therefore, in this embodiment of the present application, a dedicated bit can be used as the sensing indication field of the DMG PPDU or the EDMG PPDU, so the implementation is simpler.

The receiving end may determine, based on the sensing indication information, that the PPDU is a PPDU used for sensing measurement. The receiving end does not determine a PPDU without sensing indication information as a sensing PPDU. In this way, the sensing PPDU and the non-sensing PPDU in the communication system can be distinguished.

[0032] Furthermore, after it is determined that the PPDU is a PPDU used for sensing measurement, the receiving end does not need to listen to the channel. This helps to use communication resources more sparingly.

[0039] Furthermore, since the A-PPDU instruction field in the DMG header is used for both DMG PPDU and EDMG PPDU, the sensing instruction fields in the DMG PPDU and EDMG PPDU can be integrated, thereby reducing implementation complexity.

[0072] The following describes the technical solution of this application with reference to the attached drawings.

[0073] The technical solutions provided in embodiments of this application may be applied to wireless local area network (WLAN) scenarios.

[0074] While embodiments of this application are primarily described using examples in which a WLAN network, in particular a network to which the IEEE 802.11 system standard applies, those skilled in the art will understand that various aspects of embodiments of this application may be extended to other networks using various standards or protocols, such as Bluetooth, high-performance radio local area networks (HIPERLAN), wide area networks (WANs), personal area networks (PANs), and other networks known or to be developed in the future. Accordingly, various aspects provided in embodiments of this application are applicable to any suitable wireless network, regardless of the coverage area used and the wireless access protocol used.

[0076] The communication systems to which this application applies are merely illustrative examples and are not limited to them. This is described collectively here. Further details are not provided below.

[0079] Figure 1 is a schematic diagram of an application scenario relating to the present application. In Figure 1, the AP (AP110 shown in Figure 1) may be a communication server, router, or switch, or any one of the above network devices. The STA (STA121 or STA122 shown in Figure 1) may be a mobile phone or computer, or any one of the above terminals. This is not limited to this embodiment of the present application. One or more STAs in a station device may communicate with one or more APs in an access point device after establishing an association relationship. For example, AP110 may communicate with STA121 after an association relationship has been established between AP110 and STA121, and AP110 may communicate with STA122 after an association relationship has been established between AP110 and STA122.

[0080] It should be understood that the communication system 100 in Figure 1 is merely an example. The technical solution of the embodiment of the present invention is applicable to communication between an AP and one or more STAs, as well as to communication between APs, and furthermore, to communication between STAs.

[0081] Access points are used by terminals (e.g., mobile phones) to access wired (or wireless) networks and are primarily located in homes, buildings, and campuses. Typical coverage ranges are tens of meters or over 100 meters. Access points may, alternatively, be located outdoors. An access point is equivalent to a bridge connecting wired and wireless networks. The main function of an access point is to connect various wireless network clients together and then connect the wireless network to Ethernet. Specifically, an access point may be a terminal device (e.g., a mobile phone) or a network device (e.g., a router) equipped with a Wi-Fi chip. Optionally, an access point may be a device supporting the 802.11 series WLAN standard.

For example, a station may also support the 802.11bf standard, the 802.11ad standard, the 802.11ay standard, or future Wi-Fi standards.

[0083] For example, access points and stations may be devices used in the Internet of Vehicles, Internet of Things nodes, sensors within the Internet of Things (IoT), smart cameras, smart remote controls, smart water or electricity meters in smart homes, sensors in smart cities, and so on.

[0084] The wireless communication system provided in the embodiments of this application may be a WLAN or a cellular network. The method may be implemented by a communication device in the wireless communication system, or by a chip or processor in the communication device. The communication device may be a wireless communication device that supports parallel transmission over multiple links. For example, the communication device is called a multi-link device or a multi-band device. Compared to a device that supports only single-link transmission, a multi-link device has higher transmission efficiency and throughput. A multi-link device includes one or more affiliated STAs (STAs). An affiliated STA is a logical station and may operate on a single link. An affiliated STA may be an AP or a non-AP STA. A multi-link device in which the affiliated STA is an AP may be called a multi-link AP, a multi-link AP device, or an AP multi-link device. A multi-link device in which the affiliated STA is a non-AP STA may be called a multi-link STA, a multi-link STA device, or an STA multi-link device.

[0085] Signals transmitted by Wi-Fi devices are typically reflected, diffracted, and scattered by various obstacles before being received by terminal devices. This phenomenon means that the actual received signal is usually a superposition of multiple signals, resulting in a complex channel environment. However, this also makes it easier for the wireless signal to sense the physical environment it passes through. The surrounding environment can be inferred and perceived by analyzing the wireless signal, which has been affected by various obstacles, including channel state information. Sensing technology is derived from this.

[0086] Sensing technology involves four roles and four steps. The four roles are sensing initiator, sensing responder, sensing transmitter, and sensing receiver.

[0087] Specifically, a sensing initiator is a station that starts the sensing process. A sensing responder is a station that participates in the sensing process started by the sensing initiator. A sensing transmitter is a station that transmits physical layer protocol data units (PPDUs) for sensing measurements in the sensing process, and these PPDUs for sensing measurements are abbreviated as sensing PPDUs. A sensing receiver is a station that receives the sensing PPDUs transmitted by the sensing transmitter and performs sensing measurements in the sensing process.

[0088] One sensing technology is radar sensing, which typically features self-transmission and self-reception. An annex to standard 802.11ay provides methods for performing radar sensing according to standards 802.11ad and 802.11ay. A station (e.g., station #1) may perform radar sensing in the following ways:

[0089] (1) The PPDU used for sensing measurements, i.e., the sensing PPDU, is generated according to the DMG or EDMG standard. Both the transmitter address (TA) and receiver address (RA) in the sensing PPDU are set to the media access control (MAC) address of station #1. If the sensing PPDU is a short sector sweep (SSW) PPDU, the source associated identifier (AID) and destination associated identifier in the PPDU must be set to the same value.

[0090] (2) The sensing PPDU is transmitted based on the current channel access mechanism.

[0091] (3) After receiving the PPDU, other stations (e.g., Station #2) shall not continue unpacking the PPDU after reading the RA, and shall respect the station's transmission opportunity (TXOP) and not compete for the channel during this period.

[0092] In the above solution, radar sensing is indicated by using RA=TA. However, if the sensing PPDU is transmitted and received by different devices, for example in bistatic sensing or transmit / receive separation scenarios, the receiving end cannot determine that the PPDU is a sensing PPDU. In other words, for a receiving end device in a communication system, sensing PPDUs and non-sensing PPDUs cannot be distinguished. Thus, the receiving end cannot make the corresponding adjustments to maximize sensing performance.

[0093] In consideration of the above technical problems, an embodiment of the present invention provides an information instruction method that distinguishes between sensing PPDUs and non-sensing PPDUs in a communication system so that the receiving end can optimize its sensing performance.

[0094] The technical solutions provided herein are described in detail below with reference to the accompanying drawings. Embodiments of this invention may be applied to several different scenarios, including, but are not limited to, the scenario shown in Figure 1.

[0095] Figure 2 is a schematic flowchart of the information instruction method 200 according to an embodiment of the present application.

[0096] S210: The transmitting end generates a PPDU, which contains sensing instruction information.

[0097] The sensing instruction information indicates that the PPDU is the PPDU used for sensing measurement.

[0098] In other words, the sensing instruction information indicates that the PPDU is not the PPDU used for communication.

[0099] In other words, sensing indication information indicates that the PPDU carries a sensing signal, or that the duration indicated by the lifetime indicated by the PPDU is used to transmit the sensing signal, or that the sensing indication information indicates that the TXOP protected / set by the PPDU is used to transmit the sensing signal.

[0100] Specifically, at least one bit within the PPDU may be used as a sensing instruction field, the sensing instruction field carrying sensing instruction information, the sensing instruction field may be a dedicated instruction field, or the current instruction field may be reused.

[0101] PPDU is either a DMG single-carrier mode PPDU, an EDMG single-carrier mode PPDU, or an EDMG quadrature frequency division multiplexing mode PPDU.

[0102] PPDUs under 802.11ad are sometimes called DMG PPDUs, and it should be understood that DMG PPDUs have two types of modes: control mode and single carrier (SC) mode. PPDUs under 802.11ay are sometimes called EDMG PPDUs, and EDMG PPDUs have three types: control mode, single carrier mode (SC mode), and orthogonal frequency division multiplexing (OFDM) mode. The PPDUs of this application are PPDUs in SC mode under 802.11ad, PPDUs in SC mode under 802.11ay, or PPDUs in OFDM mode under 802.11ay, i.e., DMG SC mode PPDUs, EDMG SC mode PPDUs, or EDMG OFDM mode PPDUs.

[0103] It should be further understood that, unless otherwise specifically stated below in this application, DMG PPDU is DMG SC-mode PPDU, and EDMG PPDU is either EDMG SC-mode PPDU or EDMG OFDM-mode PPDU.

[0104] S220: The transmitting end transmits the PPDU, and the receiving end receives the PPDU accordingly.

[0105] The transmitting end transmits a PPDU containing sensing instruction information in S210, and the receiving end receives a PPDU containing sensing instruction information in S210.

[0106] S230: The receiving end determines, based on the sensing instruction information, that the PPDU is the PPDU to be used for sensing measurement.

[0107] Specifically, the receiving end can parse the PPDU, obtain sensing instruction information within the PPDU, and determine that the PPDU is one to be used for sensing measurements.

[0108] According to the above solution, the PPDU generated by the transmitting end includes sensing instruction information, which may indicate that the PPDU is a PPDU to be used for sensing measurements. The receiving end may determine, based on the sensing instruction information, that the PPDU is a PPDU to be used for sensing measurements. The receiving end does not determine a PPDU that does not contain sensing instruction information as a sensing PPDU. In this way, sensing PPDUs and non-sensing PPDUs can be distinguished in a communication system.

[0109] Furthermore, once a PPDU is determined to be the one used for sensing measurements, the receiving end does not need to listen on the channel. This helps to make better use of communication resources.

[0110] Optionally, after the receiving end determines that the PPDU is the PPDU to be used for sensing measurements, the receiving end can perform gain control in the subsequent automatic gain control (AGC) section to enhance sensing performance.

[0111] Optionally, after the receiving end has determined that the PPDU is the PPDU to be used for sensing measurements, the receiving end may prepare sensing results that need to be fed back as soon as possible.

[0112] In implementation, the PPDU is a DMG SC mode PPDU, and the DMG header field of the DMG SC mode PPDU carries sensing instruction information.

[0113] It should be noted that a DMG SC mode PPDU includes a header field, which is sometimes also called a DMG header field.

[0114] The DMG header field includes an EDMG PPDU indicator field. Specifically, the EDMG PPDU indicator field may be the B46 field in the DMG header field, which indicates whether the PPDU is an EDMG PPDU. In a DMG SC mode PPDU, if the value of the B46 field in the DMG header field is 0, it indicates that the PPDU is a DMG PPDU.

[0115] Based on the above solution, if the receiving end is not participating in any sensing, it can determine that the PPDU is a sensing PPDU by reading the sensing instruction information in the DMG header field. Furthermore, the receiving end does not need to continue performing decoding. This helps reduce the power consumption of the device.

[0116] Specifically, the additional PPDU (A-PPDU) instruction field and the training length instruction field within the DMG header field carry sensing instruction information.

[0117] The DMG header field includes an A-PPDU indicator field, which may indicate whether a PPDU is an A-PPDU. An A-PPDU means that one PPDU is followed by another PPDU, and the subsequent PPDU does not include a preamble portion.

[0118] The DMG header field further includes a training length indicator field, which indicates the length of the training (TRN) field contained in the DMG SC mode PPDU.

[0119] In this application, the A-PPDU instruction field and the training length instruction field within the DMG header field can carry sensing instruction information.

[0120] In other words, the location of the sensing indicator field is the location of the A-PPDU indicator field and the training length indicator field within the DMG header field. Alternatively, the A-PPDU indicator field and the training length indicator field within the DMG header field may together indicate whether the PPDU is a sensing PPDU.

[0121] Specifically, in 802.11ad, the A-PPDU instruction field is field B30 in the DMG header, and the training length instruction fields are fields B32 through B36 in the DMG header.

[0122] In this embodiment of the present application, it should be understood that the “Bxx field” may also be referred to as the Bxx bit. For example, the B30 field represents the B30 bit, i.e., the bit in which B30 is located.

[0123] Figure 3 is a schematic diagram of the DMG SC-mode PPDU format. As shown in Figure 3, the DMG SC-mode PPDU includes a short training field (STF) field, a channel estimation (CE) field, a header field, at least one block (BLK), automatic gain control (AGC), and a TRN field. The STF and CE fields form the preamble portion. The header field is the DMG header field. Field B30 in the header field is the A-PPDU indicator field. Fields B32 through B36 in the header field are the training length indicator fields. Fields B32 through B36 indicate the length of the TRN field. Field B46 in the DMG header field is the EDMG PPDU indicator field. In the format shown in Figure 3, the value of field B46 is 0. Fields B30 and B32 through B36 may indicate the following information:

[0124] (1) If the value of field B30 is 1 and the values ​​of fields B32 through B36 are 0, then the PPDU is an A-PPDU. If the PPDU is an A-PPDU, the PPDUs following it do not carry an STF field or a CE field.

[0125] (2) If the value of field B30 is 0 and the values ​​of fields B32 through B36 are 0, then the PPDU is a non-A-PPDU that does not carry the TRN field.

[0126] (3) If the value of field B30 is 0 and the values ​​of fields B32 through B36 are not 0, then the PPDU is a non-A-PPDU carrying the TRN field.

[0127] (4) If the value of field B30 is 1 and the values ​​of fields B32 through B36 are not 0, then the PPDU is a sensing PPDU.

[0128] Specifically, the TRN field carried by the sensing PPDU can be used for sensing. If the value of B30 is 1 and the values ​​of B32 through B36 are not 0, the receiving end determines that the DMG SC mode PPDU is a sensing PPDU based on the B30 field and the B32 through B36 fields. Furthermore, the receiving end may parse the contents of the TRN field and perform sensing based on the contents of the TRN field.

[0129] Therefore, in this embodiment of the present application, the current instruction field can be reused, and the instruction of the sensing PPDU is implemented without introducing a new instruction field, thus helping to save resources.

[0130] Furthermore, if B30=1 and the training length indicator field is not 0, this does not occur in DMG SC mode PPDUs generated by devices not participating in sensing. Therefore, DMG SC mode PPDUs generated by devices not participating in sensing do not cause misreadings by DMG devices participating in sensing. However, DMG SC mode PPDUs generated by devices participating in sensing have the characteristics of B30=1 and a training length that is not 0. Therefore, when reading the B36 field from the B30 and B32 fields, it can be considered that an error has occurred in the PPDU for DMG devices not participating in sensing, meaning that misreadings by DMG devices not participating in sensing do not occur.

[0131] In other words, the solution of this application can be compatible with current protocols and have better scalability.

[0132] Furthermore, since the training length indicator field can indicate the length of the training field, and the training field is used to perform sensing, the A-PPDU indicator field and the description portion of the training field used for sensing (i.e., the training length indicator field) are used together as the sensing indicator field. This solution is more compact and efficient because, once the receiving end determines that the PPDU is a sensing PPDU, it can further determine the length of the training field used for sensing.

[0133] In implementation, the PPDU is either an EDMG SC mode PPDU or an EDMG OFDM mode PPDU, which includes an L-header field, and the L-header field carries the sensing instruction field.

[0134] It should be understood that the 802.11ay protocol is compatible with the 802.11ad protocol. In the case of EDMG PPDUs, the L-header field is sometimes called the non-EDMG header field of the EDMG PPDU, or the DMG header field of the EDMG PPDU.

[0135] The L-header field contains an EDMG PPDU indicator field. Specifically, the EDMG PPDU indicator field may be the B46 field in the L-header field, which indicates whether the PPDU is an EDMG PPDU. For an EDMG PPDU, if the value of the B46 field in the L-header field is 1, it indicates that the PPDU is an EDMG PPDU.

[0136] Based on the above solution, if the receiving end is not participating in any sensing, it can determine that a PPDU is a sensing PPDU by reading the sensing instruction information in the L-header field. Furthermore, the receiving end does not need to continue performing decoding. This helps reduce the power consumption of the device.

[0137] Specifically, in the case of EDMG SC mode PPDU or EDMG OFDM mode PPDU, the L-header field also includes the A-PPDU instruction field. The A-PPDU instruction field within the L-header field can carry sensing instruction information.

[0138] In other words, the location of the sensing indicator field is the location of the A-PPDU indicator field within the L-header field. Alternatively, the A-PPDU indicator field within the L-header field indicates whether the PPDU is a sensing PPDU.

[0139] Specifically, in the 802.11ay protocol, the A-PPDU indicator field in the L-header field is the B30 field in the L-header.

[0140] Figure 4 is a schematic diagram of the EDMG SC-mode PPDU format. As shown in Figure 4, the EDMG SC-mode PPDU includes the L-STF field, the L-channel estimation field (CEF) field, the L-header field, the EDMG-header-A field, the EDMG-STF field, the EDMG-CEF field, the EDMG-header-B field, the data field, and the TRN field. The L-STF and L-CEF fields form the preamble portion. The L-header field is sometimes also called the DMG header of the EDMG SC-mode PPDU, and the B30 field within the L-header field is the A-PPDU indicator field, and the B46 field within the L-header field is the EDMG PPDU indicator field. In the format shown in Figure 4, the value of the B46 field is 1.

[0141] For a non-sensing EDMG SC mode PPDU, the value of the B30 field is 0. If the value of B30 is 1, the EDMG SC mode PPDU is a sensing PPDU.

[0142] In the case of an EDMG OFDM mode PPDU, the header format is the same as that of an EDMG SC mode PPDU. Therefore, the position of the sensing indicator field in an EDMG OFDM mode PPDU is the same as that of an EDMG SC mode PPDU. Specifically, in the case of a non-sensing EDMG OFDM mode PPDU, the value of the B30 field is 0. If the value of the B30 field is 1, the EDMG OFDM mode PPDU is a sensing PPDU.

[0143] Therefore, in this embodiment of the present application, the current instruction field can be reused, and the instruction of the sensing PPDU is implemented without introducing a new instruction field, thus helping to save resources.

[0144] Furthermore, since the A-PPDU instruction field in the DMG header is used for both DMG PPDU and EDMG PPDU, the sensing instruction fields in the DMG PPDU and EDMG PPDU can be integrated, thereby reducing implementation complexity.

[0145] Optionally, an EDMG SC mode PPDU or an EDMG OFDM mode PPDU may further include a training field. Specifically, it should be understood that the training field of a sensing PPDU may be used for sensing, as shown in Figure 4. The training field includes two format types: the format of the training field used in the DMG PPDU, and the dedicated training field format within the EDMG PPDU. The two formats of the training field are referred to as the DMG training field and the EDMG training field, respectively.

[0146] The training field included in an EDMG SC mode PPDU or an EDMG OFDM mode PPDU may be a DMG training field or an EDMG training field. An EDMG single-carrier mode PPDU or an EDMG quadrature frequency division multiplexing mode PPDU includes an EDMG-Header-A field, and the DMG Training (DMG TRN) indicator field within the EDMG-Header-A field indicates that the PPDU includes a DMG training field or that the PPDU includes an EDMG training field.

[0147] Specifically, in the 802.11ay protocol, the DMG training instruction field is the B101 field within the EDMG-Header-A field.

[0148] Accordingly, in this embodiment of the present application, the types of training fields included in the PPDU may be further indicated so that the receiving end can parse the training fields based on the corresponding types and perform sensing based on the training fields.

[0149] In the example, the DMG training instruction field indicates that the training field included in the EDMG SC mode PPDU or EDMG OFDM mode PPDU is a DMG training field.

[0150] In this case, the training length indicator field in the L-header field of the EDMG SC mode PPDU or EDMG OFDM mode PPDU indicates the length of the DMG training field.

[0151] In other words, if the training field included in the EDMG PPDU is the DMG training field, then the training length indicator field in the L-header field may indicate the length of the DMG training field.

[0152] Specifically, in the 802.11ay protocol, the L-header field of an EDMG SC mode PPDU or EDMG OFDM mode PPDU includes the training length indicator field, which is fields B32 through B36 within the L-header.

[0153] Therefore, if the training field included in the EDMG PPDU is a DMG training field, in this embodiment of the present application, the training length indicator field in the L-header field may indicate the length of the DMG training field included in the PPDU, so that the receiving end can parse the training field and further facilitate the performance of sensing.

[0154] In another example, the DMG training instruction field indicates that the training field included in the EDMG SC mode PPDU or EDMG OFDM mode PPDU is an EDMG training field.

[0155] In this case, the DMG Training Length (DMG TRN Length) indicator field in the EDMG-Header-A field of the EDMG SC mode PPDU or EDMG OFDM mode PPDU indicates the length of the EDMG training field, and the value of the Training Length indicator field in the L-Header field of the EDMG SC mode PPDU or EDMG OFDM mode PPDU is 0.

[0156] Specifically, in the 802.11ay protocol, the EDMG-Header-A field of an EDMG SC mode PPDU or EDMG OFDM mode PPDU contains the DMG training length indicator field, which is fields B64 through B71 within the EDMG-Header-A field.

[0157] In other words, if the training field included in the EDMG PPDU is an EDMG training field, the value of the training length indicator field in the L-header field is 0. In this case, the training length indicator field in the EDMG-header-A field of the EDMG PPDU may indicate the length of the EDMG training field in the PPDU.

[0158] Therefore, if the training field included in the EDMG PPDU is an EDMG training field, in this embodiment of the present application, the training length indicator field in the EDMG-Header-A field may indicate the length of the EDMG training field included in the PPDU, so that the receiving end can parse the training field and further facilitate the performance of sensing.

[0159] It should be understood that the above relationship between the training length indicator field and the training field is merely two examples, and is not limited to this application. For example, if the training field contained in the EDMG PPDU is a DMG training field, a person skilled in the art could design the training length indicator field in the L-header field to 0 and use the training length indicator field in the EDMG-header-A field of the EDMG PPDU to indicate the length of the DMG training field in the PPDU.

[0160] In implementation, the B47 field within the DMG header field of the DMG SC mode PPDU carries sensing instruction information.

[0161] As shown in Figure 3, the DMG header of a DMG SC mode PPDU further includes a reserved bit, for example, the B47 field. The reserved bit may be used as a sensing indicator field to indicate whether the DMG PPDU is a sensing PPDU.

[0162] Therefore, in this embodiment of the present application, implementation is simpler because a dedicated bit can be used as the sensing instruction field of the DMG PPDU.

[0163] In implementation, the B47 field in the L-header field of the EDMG SC mode PPDU or EDMG OFDM mode PPDU carries sensing instruction information.

[0164] As shown in Figure 4, the L-header of the EDMG SC mode PPDU also includes a reserve bit, for example, the B47 field. The reserve bit may be used as a sensing indicator field to indicate whether the EDMG SC mode PPDU is a sensing PPDU.

[0165] Similarly, the reserve bits of the EDMG OFDM mode PPDU, for example, the B47 field, may be used as a sensing indicator field to indicate whether the EDMG OFDM mode PPDU is a sensing PPDU.

[0166] Therefore, in this embodiment of the present application, implementation is simpler because a dedicated bit can be used as the sensing instruction field of the EDMG PPDU.

[0167] Furthermore, since the reserve bits in the DMG header can be used for both DMG PPDUs and EDMG PPDUs, the sensing instruction fields of DMG PPDUs and EDMG PPDUs can be integrated, reducing implementation complexity.

[0168] In implementation, the EDMG SC mode PPDU or EDMG OFDM mode PPDU includes an EDMG-Header-A field, which carries sensing instruction information.

[0169] As shown in Figure 4, the EDMG SC mode PPDU further includes an EDMG-Header-A field. Below are two implementations in which the EDMG-Header-A field carries sensing instruction information.

[0170] Method 1: One of the reserve bits in the EDMG-Header-A field carries sensing instruction information.

[0171] Specifically, any of the reserved bits in the EDMG-Header-A, for example, any bit in fields B102 through B111, can be used as a sensing indicator field to indicate whether the EDMG SC mode PPDU is a sensing PPDU.

[0172] Similarly, any of the reserved bits in the EDMG OFDM mode PPDU, for example, any bit in the B102 to B111 fields, can be used as a sensing indicator field to indicate whether the EDMG OFDM mode PPDU is a sensing PPDU.

[0173] Therefore, in this embodiment of the present application, implementation is simpler because a dedicated bit can be used as the sensing instruction field of the EDMG PPDU.

[0174] Furthermore, in the case of EDMG PPDU, the reserve bits in the EDMG-Header-A field can be used, thereby improving the diversity and flexibility of the solution implementation.

[0175] Method 2: The additional EDMG PPDU instruction field (additional EDMG PPDU) and the EDMG training length instruction field within the EDMG-Header-A field carry sensing instruction information.

[0176] The EDMG-Header-A field includes an additional EDMG PPDU indicator field. This additional EDMG PPDU indicator field may indicate whether the EDMG PPDU is an A-PPDU. An A-PPDU means that one PPDU is followed by another PPDU, and the subsequent PPDU does not include a preamble portion.

[0177] The EDMG-Header-A field further includes an EDMG training length indicator field, which may indicate the length of the EDMG training field contained in the DMG PPDU.

[0178] In this application, in the case of EDMG SC mode PPDU or EDMG OFDM mode PPDU, the additional EDMG PPDU instruction field and EDMG training length instruction field in the EDMG-Header-A field may carry sensing instruction information.

[0179] In other words, the location of the sensing indicator field is the location of the additional EDMG PPDU indicator field and the EDMG training length indicator field within the EDMG-Header-A field. Alternatively, the additional EDMG PPDU indicator field and the EDMG training length indicator field within the EDMG-Header-A field may together indicate whether the PPDU is a sensing PPDU.

[0180] Specifically, in the 802.11ay protocol, field B95 in the EDMG-Header-A field is the additional EDMG PPDU instruction field, and fields B64 through B71 in the EDMG-Header-A field are the EDMG training length instruction fields.

[0181] Therefore, in this embodiment of the present application, the current instruction field can be reused, and the instruction of the sensing PPDU is implemented without introducing a new instruction field, thus helping to save resources.

[0182] It should be understood that the two implementations described above, in which the EDMG-Header-A field carries sensing instruction information, are merely examples. The specific location of the sensing instruction information within the EDMG-Header-A field is not limited in this application.

[0183] The above describes the method embodiment in the present invention, and the following describes the corresponding apparatus embodiment. The description of the apparatus embodiment corresponds to the description of the method embodiment, and therefore, it should be understood that for parts not described in detail, one should refer to the method embodiment described above.
