DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

There is no order, nor does it indicate any special limitation on the number of objects in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application.

For example, at least one of a, b or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, where each of a, b and c can itself be an element or a set containing one or more elements.

[0056] In this application, "exemplary", "in some embodiments", "in other embodiments", etc. are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0057] The structures of each frame given in this application are only examples. Each frame may include more or fewer fields, and this application does not limit this.

[0058] In order to explain the present application more clearly, the relevant technologies involved in the present application are first introduced below.

[0059] In a wireless local area network, when two devices send data, they can encapsulate the data through the data link layer and / or the physical layer. The Institute of Electrical and Electronics Engineers (IEEE) 802.11 defines the data link layer and the physical layer, where the data link layer is divided into the logical link control (LLC) layer and the media access control (MAC) layer; the physical (Physical, PHY) layer is divided into the physical layer convergence procedure (PLCP) layer and the physical medium dependent (PMD) layer.

[0060] When data from the network layer enters the data link layer, it first passes through the LLC layer and adds some information to form a media access control service data unit (MAC Service Data Unit, MSDU). The MSDU enters the MAC layer, and after adding the MAC header information and the tail FCS check information to the MSDU, it is converted into an MPDU, i.e., a MAC frame, by the wireless network card driver. When the MPDU enters the physical layer, its name becomes the physical layer convergence process service data unit (PLCP Service Data Unit, PSDU), i.e., the PSDU is the same as the MPDU. After receiving the PSDU, the PLCP adds a preamble synchronization code and a PHY header in front of the PSDU to form a physical layer protocol data unit (Physical Protocol Data Unit, PPDU). Then, the PPDU will be handed over to the PMD layer and modulated into a bit stream for transmission according to different algorithms.

[0061] Among them, the structure of MPDU is as follows Figure 1 As shown, it includes: a MAC header, a frame body (Frame Body) and an FCS, wherein the MAC header includes a frame control (Frame Control) field, a duration (Duration) / identifier (Identifier, ID) field, an address (Address) 1 field, an address 2 field, an address 3 field, a sequence control (Sequence Control) field, an address 4 field, a quality of service (Quality of Service, QoS) control field and an HT control field.

[0062] When the Type subfield is not equal to 1 or the Subtype subfield is not equal to 6, the structure of the Frame Control field of a non-S1G MPDU (S1G (Sub 1GHz): supports devices running below 1 GHz) is as follows: Figure 2 As shown, it includes: Protocol Version subfield, Type subfield, Subtype subfield, To Distribution System (DS) subfield, From DS subfield, More Fragments subfield, Retry subfield, Power Management subfield, More Data subfield, Protected Frame subfield and High Throughput Control (+HTC) subfield.

[0063] The +HTC subfield in the frame control field indicates whether the HT control field exists.

[0064] When the value corresponding to the retry subfield in the frame control field is 1, it indicates that the data MPDU or management MPDU carrying the retry subfield is a retransmission MPDU to help the receiving end eliminate duplicate frames.

[0065] The MPDU for which the retry subfield is effective cannot be an MPDU of the block acknowledgment protocol or an aggregated MPDU. However, in practice, MPDUs are usually MPDUs of the block acknowledgment protocol or an aggregated MPDU. In addition, for an MPDU for which the retry subfield is effective, the receiving end can check the sequence control field to confirm whether the MPDU is a retransmitted MPDU. Therefore, the use of the retry subfield is becoming less and less.

[0066] The structure of the HT control field is as follows Figure 3 As shown, when the variant is HT, the HT control field includes an HT control middle (ControlMiddle) subfield, an access category (AC) constraint (Constraint) subfield, and a reverse direction grant (RDG) / more PPDU subfield; when the variant is very high throughput (VHT), the HT control field includes a VHT control middle subfield, an AC constraint subfield, and an RDG / more PPDU subfield; when the variant is high efficiency (HE), the HT control field includes an A control subfield.

[0067] The HT control field carries link signaling and / or parameters to notify the peer end, wherein the HT control middle subfield corresponds to the IEEE802.11n standard, the VHT control middle subfield corresponds to the IEEE 802.11ac standard, and the A control subfield corresponds to the IEEE802.11ax, IEEE802.11be and other standards.

[0068] With the evolution of technology and the continuous increase in link signaling and / or parameters, the available space of the HT control field is getting smaller and smaller, and it is unable to carry more newly emerging link signaling and / or parameters.

[0069] In order to solve the above technical problem, the present application multiplexes the first control field on the HT control field, or adds the first control field to the MAC header of the MPDU, so that the MAC header can carry more link signaling and / or parameters.

[0070] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or displayed content will not be repeatedly described in different embodiments.

[0071] Figure 4 A flow chart of a communication method provided in an embodiment of the present application. Figure 4 , the method comprising:

[0072] S401. Transmit an MPDU, wherein the MAC header of the MPDU includes a multiplexing field, a first subfield, and a +HTC subfield, or the MAC header includes an HT control field, a first control field, a first subfield, and a +HTC subfield, and the multiplexing field is the HT control field or the first control field.

[0073] The execution subject of the embodiments of the present application may be a non-access point station (STA), an access point (AP), or a communication device set in a STA or AP. The communication device may be implemented by software or by a combination of software and hardware.

[0074] Transmitting an MPDU may refer to sending an MPDU or receiving an MPDU.

[0075] For example, the STA sends an MPDU to the AP, that is, the AP receives the MPDU sent by the STA.

[0076] In another example, the AP sends an MPDU to the STA, that is, the STA receives the MPDU sent by the AP.

[0077] In another example, STA1 sends an MPDU to STA2, that is, STA2 receives the MPDU sent by STA1.

[0078] In another example, AP1 sends an MPDU to AP2, that is, AP2 receives the MPDU sent by AP1.

[0079] In a possible implementation manner, the first subfield may be used to indicate whether the first control field exists.

[0080] The first subfield may also be referred to as an ultra-high reliability control (Ultra High Reliability Control, +UHRC) subfield, or may be referred to as other subfields, which is not limited in this application.

[0081] In a possible implementation, the first subfield multiplexes the retry subfield, that is, the position of the first subfield in the MPDU is the same as the position of the retry subfield.

[0082] Multiplexing means that in IEEE802.11bn and later versions, the subfield located at the above position (B11 bit of the frame control field) is the first subfield; in versions before IEEE802.11bn, the subfield located at the above position is the retry subfield.

[0083] When the subfield at the above position is the first subfield, whether the MPDU carrying the first subfield is a duplicate frame can be determined in the following manner:

[0084] Determine whether there is a sequence number corresponding to the MPDU in the receiving buffer; if so, determine that the MPDU is a duplicate frame.

[0085] By multiplexing the retry subfield with the first subfield, the usage of the retry subfield can be extended.

[0086] In a possible implementation manner, the first control field may be used to indicate subsequent newly occurring signaling and / or parameters.

[0087] Exemplarily, the first control field is used to indicate at least one of the following:

[0088] Multi-AP coordination control signaling and / or parameters;

[0089] Direct link cache status report control signaling and / or parameters;

[0090] Link adaptation control signaling and / or parameters;

[0091] Multi-link power management control signaling and / or parameters;

[0092] Roaming control signaling and / or parameters;

[0093] sub-channel access control signaling and / or parameters;

[0094] security control signaling and / or parameters;

[0095] Artificial intelligence control signaling and / or parameters;

[0096] Machine learning control signaling and / or parameters;

[0097] Low-latency flow control signaling and / or parameters;

[0098] Hybrid automatic repeat request control signaling and / or parameters;

[0099] Aggregate physical protocol data unit control signaling and / or parameters;

[0100] Cross-link traffic indication control signaling and / or parameters;

[0101] Multilink pause control signaling and / or parameters.

[0102] The first control field may be referred to as an ultra high reliability (Ultra High Reliability, UHR) control field, or may be referred to as other fields, which is not limited in this application.

[0103] The following describes how to indicate the first control field located at different positions in two cases.

[0104] Case 1: The first control field is multiplexed with the HT control field.

[0105] That is, the MAC header of the MPDU includes a multiplexing field, a first subfield and a +HTC subfield, and the multiplexing field is the HT control field or the first control field.

[0106] In a possible implementation manner, the first subfield may be used to indicate that the multiplexing field is the first control field, and / or the +HTC subfield may indicate that the multiplexing field is the HT control field.

[0107] Exemplarily, when the first subfield is 1, it may indicate that the multiplexing field is the first control field; when the first subfield is 0, it may indicate that the multiplexing field is not the first control field.

[0108] When the +HTC subfield is 1, it may indicate that the multiplexing field is the HT control field, and when the +HTC subfield is 0, it may indicate that the multiplexing field is not the HT control field.

[0109] When the first subfield is 0 and the +HTC subfield is 0, it may indicate that there is no multiplexing field.

[0110] In a possible implementation manner, the first control field includes an unmodified first control field or a modification of the first control field.

[0111] That is, the MAC header of the MPDU includes a multiplexing field, a first subfield and a +HTC subfield, and the multiplexing field is the HT control field, the unmodified first control field or a modification of the first control field.

[0112] In a possible implementation manner, the first subfield and the +HTC subfield may be combined to indicate a multiplexing field.

[0113] When the value indicated by the +HTC subfield and the first subfield is the first value, it may indicate that the multiplexing field is the HT control field;

[0114] When the +HTC subfield and the value indicated by the first subfield are the second value, it may indicate that the multiplexing field is the unmodified first control field;

[0115] When the +HTC subfield and the value indicated by the first subfield are the third value, it may indicate that the multiplexing field is a first variant of the first control field;

[0116] When the value indicated by the +HTC subfield and the first subfield is the fourth value, it may indicate that the multiplexing field does not exist.

[0117] Among them, the first value, the second value, the third value and the fourth value are different.

[0118] Exemplarily, the multiplexing fields may be indicated by the following table:

[0119] +HTC subfield First subfield Multiplexing Field 1 0 HT Control Field 1 1 Unmodified first control field 0 1 Variants of the first control field 0 0 Does not exist

[0120] Note: when the +HTC subfield is 0, it may cause compatibility issues. Therefore, when the device versions of both communicating parties are IEEE802.11bn and subsequent versions, they can be parsed according to the above table. Alternatively, the MPDU in the PPDU of IEEE802.11bn and subsequent versions can be parsed according to the above table.

[0121] The purpose of the HT Control field can be expanded without increasing the size of the MAC header, that is, the HT Control field in the MAC header can carry more link signaling and / or parameters without increasing the size of the MAC header.

[0122] Case 2: Add the first control field in the MAC header.

[0123] That is, the MAC header of the MPDU includes the HT control field, the first control field, the first subfield and the +HTC subfield.

[0124] At this time, the first subfield may be used to indicate whether the first control field exists, and the +HTC subfield may be used to indicate whether the HT control field exists.

[0125] Exemplarily, when the first subfield is 1, it may indicate that the first control field exists; when the first subfield is 0, it may indicate that the first control field does not exist.

[0126] When the +HTC subfield is 1, it may indicate that the HT Control field exists, and when the +HTC subfield is 0, it may indicate that the HT Control field does not exist.

[0127] The MAC header of the MPDU may carry both the HT control field and the first control field, that is, by adding the first control field, the MAC header may carry more link signaling and / or parameters.

[0130] In a possible implementation manner, the first subfield multiplexes the retry subfield.

[0131] In a possible implementation manner, the first subfield is used to indicate that the multiplexing field is a first control field, and / or the +HTC subfield is used to indicate that the multiplexing field is an HT control field.

[0132] In a possible implementation manner, the first control field includes an unmodified first control field or a modification of the first control field.

[0133] In a possible implementation manner, the first subfield and the +HTC subfield are used to combine and indicate a multiplexing field.

[0138] In a possible implementation, when the MAC header includes the HT control field and the first control field, the first subfield is used to indicate whether the first control field exists, and the +HTC subfield is used to indicate whether the HT control field exists.
