Description
本发明涉及通信技术领域,尤其涉及一种数据传输方法及相关设备。The present invention relates to the field of communications technologies, and in particular, to a data transmission method and related equipment.
无线保真(Wireless Fidelity,WiFi)是一种基于电气和电子工程师协会(Institute of Electrical and Electronics Engineers,IEEE)802.11标准中的无线局域网技术,用于将个人电脑(Personal Computer,PC)、手持设备(如平板电脑、手机)等终端以无线方式互相连接。无线局域网络可以包括接入点(Access Point,AP)和用户站点(简称:站点(Station,STA))。STA可以与AP进行数据传输,但STA之间的数据传输需通过AP进行转发。因此,当STA之间进行数据传输时,一个STA先将数据传输给AP,再由AP传输给另一个STA,可见,在这个过程中,在两个不同时间段分别使用了信道,以致降低了信道利用率。Wireless Fidelity (WiFi) is a wireless LAN technology based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for personal computers (PCs), handheld devices. Terminals such as tablets and mobile phones are connected to each other wirelessly. The wireless local area network may include an access point (AP) and a user site (abbreviation: station (STA)). The STA can perform data transmission with the AP, but the data transmission between the STAs needs to be forwarded through the AP. Therefore, when data transmission between STAs is performed, one STA transmits data to the AP first, and then the AP transmits to another STA. It can be seen that in this process, channels are respectively used in two different time periods, so that the channel is reduced. Channel utilization.
为了解决上述问题,IEEE802.11标准中提出了直连链路(Direct Link),即两个STA之间不需要经过AP就可以直接进行数据传输。然而,当这两个STA进行数据传输时,如果存在离这两个STA较近的第三STA,第三STA也会侦听到这两个STA用于传输数据的传输帧,而传输帧包括物理头和媒体访问控制(Media Access Control,MAC)头,接收STA在解析传输帧时,是按照物理头到MAC头的顺序进行解析的,而用于识别传输帧是否为直连传输帧的信息包括在MAC头中,以致需要解析完MAC头之后才能确定传输帧是否为直连传输帧,以致降低了直连传输帧的识别效率。In order to solve the above problem, the IEEE 802.11 standard proposes a direct link (Direct Link), that is, the two STAs can directly perform data transmission without going through the AP. However, when the two STAs perform data transmission, if there is a third STA that is closer to the two STAs, the third STA also listens to the transmission frames used by the two STAs to transmit data, and the transmission frame includes The physical head and the media access control (MAC) header, when the receiving STA parses the transmission frame, parses the physical header to the MAC header, and identifies whether the transmission frame is a direct transmission transmission frame. It is included in the MAC header, so that it is necessary to parse the MAC header before determining whether the transmission frame is a direct transmission transmission frame, so that the recognition efficiency of the direct transmission transmission frame is reduced.

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
本发明实施例公开了一种数据传输方法及相关设备,用于提高直连传输帧类型的识别效率。以下分别进行详细说明。The embodiment of the invention discloses a data transmission method and related device, which are used for improving the recognition efficiency of a direct connection transmission frame type. The details are described below separately.
为了更好地理解本发明实施例公开的一种数据传输方法及相关设备,下面先对本发明实施例使用的网络架构进行描述。请参阅图1a,图1a是本发明实施例公开的一种数据传输网络架构示意图。如图1a所示,该数据传输网络架构可以包括STA1-STA6以及AP,STA1与STA2间通过AP进行数据传输,STA1与STA2间的链路为非直连链路,STA3与STA4间以及STA5与STA6间直接进行数据传输,即STA3与STA4间以及STA5与STA6的链路为直连链路。直连链路的建立方法包括通道直接链路建立(Tunneled Direct Link Setup,TDLS)与直接链路建立(Direct Link Setup,DLS)。请参阅图1b,图1b是本发明实施例公开的一种数据传输示意图。如图1b所示,是STA3与STA4间分别为已建立直连链路和未建立直连链路时,STA3向STA4传输数据的示意图,当STA3与STA4间已建立直连链路时,STA3向STA4发送数据的传输帧为直连传输帧,当STA3与STA4间未建立直连链路时,STA3向AP与AP向STA4发送数据的传输帧为非直连传输帧,非直连传输帧可以包括上行传输帧和下行传输帧。在图1(a)所示的示意图中,当STA3向STA4进行数据传输时,由于STA2离STA4较近,STA2可能会接收到STA3向STA4发送的传输帧,因此,STA2需要识别这个传输帧是不是直连传输帧。For a better understanding of a data transmission method and related device disclosed in the embodiments of the present invention, the network architecture used in the embodiment of the present invention is described below. Referring to FIG. 1a, FIG. 1a is a schematic diagram of a data transmission network architecture disclosed in an embodiment of the present invention. As shown in FIG. 1a, the data transmission network architecture may include STA1-STA6 and an AP, and STA1 and STA2 perform data transmission through the AP, and the link between STA1 and STA2 is an indirect link, between STA3 and STA4, and STA5 and The STA6 directly performs data transmission, that is, the link between STA3 and STA4 and the link between STA5 and STA6 is a direct link. Direct link establishment methods include Tunneled Direct Link Setup (TDLS) and Direct Link Setup (DLS). Referring to FIG. 1b, FIG. 1b is a schematic diagram of data transmission disclosed in an embodiment of the present invention. As shown in FIG. 1b, when STA3 and STA4 are respectively connected to each other and the direct link is not established, STA3 transmits data to STA4. When a direct link is established between STA3 and STA4, STA3 The transmission frame for transmitting data to STA4 is a direct connection transmission frame. When a direct link is not established between STA3 and STA4, the transmission frame in which STA3 sends data to the AP and the AP to STA4 is a non-direct transmission frame, and the non-directly connected transmission frame. It may include an uplink transmission frame and a downlink transmission frame. In the schematic diagram shown in FIG. 1(a), when STA3 performs data transmission to STA4, STA2 may receive a transmission frame sent by STA3 to STA4 because STA2 is closer to STA4. Therefore, STA2 needs to identify that the transmission frame is Not a direct transmission frame.
基于图1所示的数据传输网络架构,请参阅图2,图2是本发明实施例公开的一种数据传输方法的流程示意图。其中,本发明实施例是从生成传输帧的
站点和接收传输帧的站点的角度来描述的,生成传输帧的站点是已建立直连链路的站点。如图2所示,该数据传输方法可以包括以下步骤。Based on the data transmission network architecture shown in FIG. 1 , please refer to FIG. 2 , which is a schematic flowchart of a data transmission method according to an embodiment of the present invention. Wherein, the embodiment of the present invention is to generate a transmission frame.
Described as the site and the point at which the station transmitting the frame is received, the station that generated the transmission frame is the station that has established the direct link. As shown in FIG. 2, the data transmission method may include the following steps.
201、发送站点生成包括第一字段的传输帧。201. The transmitting station generates a transmission frame including the first field.
本实施例中,当发送站点需要向其它站点传输数据时,发送站点将生成用于传输数据的传输帧,传输帧可以为直连传输帧,也可以为上行传输帧,还可以下行传输帧。该传输帧可以包括物理头,物理头可以包括第一字段。第一字段可以为高效率信令域中基本服务集(Basic Service Set,BSS)颜色(color)字段或BBS子颜色(subcolor)字段。BSS由AP和与其关联的STA组成。由于不同BSS将采用不同的颜色进行标示,所以根据BSS Color字段,STA可以识别出所收到的传输帧是否来自STA所在的BSS。此外,在一个BSS内部,BSS SubColor字段是用于对同一BSS内的不同分组进行标识。当第一字段的值为第一预设值或第一预设范围内的值时,表明传输帧为直连传输帧;当第一字段的值为第二预设范围内的值时,表明传输帧为非直连传输帧,此时第一字段的值可以指示基本服务集颜色字段的颜色或基本服务集子颜色字段的子颜色。为了避免发生冲突,第一预设范围与第二预设范围必须无交集,且第一预设值不属于第二预设范围。其中,传输帧还可以包括MAC头,物理头在传输帧中处于MAC头之前。其中,非直连传输帧可以包括上行传输帧和下行传输帧。In this embodiment, when the transmitting station needs to transmit data to other stations, the transmitting station generates a transmission frame for transmitting data, and the transmission frame may be a direct transmission frame, an uplink transmission frame, or a downlink transmission frame. The transmission frame may include a physical header, and the physical header may include a first field. The first field may be a Basic Service Set (BSS) color field or a BBS subcolor field in a high efficiency signaling domain. The BSS consists of an AP and its associated STAs. Since different BSSs will be marked with different colors, according to the BSS Color field, the STA can recognize whether the received transmission frame is from the BSS where the STA is located. In addition, within one BSS, the BSS SubColor field is used to identify different packets within the same BSS. When the value of the first field is a value of the first preset value or the first preset range, indicating that the transmission frame is a direct transmission frame; when the value of the first field is a value within the second preset range, indicating The transmission frame is a non-directly connected transmission frame, and the value of the first field may indicate the color of the basic service set color field or the sub-color of the basic service set sub-color field. In order to avoid conflicts, the first preset range and the second preset range must have no intersection, and the first preset value does not belong to the second preset range. The transmission frame may further include a MAC header, and the physical header is in front of the MAC header in the transmission frame. The non-directly connected transmission frame may include an uplink transmission frame and a downlink transmission frame.
在一个实施例中,当第一字段的值为第一预设范围内的值时,第一字段的值不仅可以指示传输帧为直连传输帧,而且还可以指示发送站点所在直连链路的标识,即指示传输帧的源站点与目的站点间的直连链路的标识,源站点即发送站点。可以标识出用于传输该传输帧的直连链路的标识。可以对所有站点预先分配标识,使第一字段的值包括源站点的标识或目的站点的标识,以便指示发送站点传输该传输帧的直连链路的标识。也可以对站点间的链路预先进行标识,如STA1与STA2间的链路标识为1、STA3与STA4间的链路标识为2等,可以使第一字段的值包括源站点与目的站点间链路的标识,以便指示发送站点传输该传输帧的直连链路的标识。In an embodiment, when the value of the first field is a value in the first preset range, the value of the first field may not only indicate that the transmission frame is a direct transmission frame, but may also indicate a direct link where the transmitting station is located. The identifier of the direct link between the source site and the destination site indicating the transmission frame, and the source site is the sending site. The identity of the direct link used to transmit the transport frame can be identified. The identifier may be pre-assigned to all sites such that the value of the first field includes the identity of the source site or the identity of the destination site to indicate the identity of the direct link to which the transmitting site transmits the transport frame. The link between the sites may be pre-identified. For example, the link identifier between STA1 and STA2 is 1. The link identifier between STA3 and STA4 is 2. The value of the first field may be included between the source site and the destination site. The identity of the link to indicate the identity of the direct link to which the transmitting station transmits the transport frame.
在一个实施例中,物理头还可以包括字段集,字段集可以包括传输流个数(Number of Space-time streams,Nsts)指示字段、空时编码(Space-time Block
Coding,STBC)指示字段、波束成形(Transmission Beamforming,TxBF)指示字段和双载波调制(Dual Carrier Modulation,DCM)指示字段中至少一种,当第一字段的值为第一预设值时,即当传输帧为直连传输帧时,字段集可以指示发送站点所在直连链路的标识,即指示传输帧的源站点与目的站点间的直连链路的标识,源站点即发送站点。可以标识出用于传输该传输帧的直连链路的标识。请参阅图12a,图12a是本发明实施例公开的第一字段为高效率信令域中BSS颜色字段或BBS子颜色字段的示意图,请参阅图12b,图12b是本发明实施例公开的第一字段为高效率信令域中BSS颜色字段或BBS子颜色字段,且Nsts指示字段、STBC指示字段、TxBF指示字段和DCM指示字段属于高效率信令域的示意图。In an embodiment, the physical header may further include a field set, and the field set may include a Number of Space-time streams (Nsts) indication field and a space-time coding (Space-time Block).
Coding, STBC) at least one of a indication field, a beamforming (TxBF) indication field, and a dual carrier modulation (DCM) indication field, when the value of the first field is a first preset value, that is, When the transmission frame is a direct transmission frame, the field set may indicate the identity of the direct link where the transmitting station is located, that is, the identifier of the direct link between the source site and the destination site indicating the transmission frame, and the source site is the transmitting site. The identity of the direct link used to transmit the transport frame can be identified. Referring to FIG. 12a, FIG. 12a is a schematic diagram of a first field in the embodiment of the present invention, which is a BSS color field or a BBS sub-color field in a high-efficiency signaling domain. Referring to FIG. 12b, FIG. 12b is a disclosure of an embodiment of the present invention. One field is a BSS color field or a BBS sub-color field in a high efficiency signaling domain, and the Nsts indication field, the STBC indication field, the TxBF indication field, and the DCM indication field belong to a schematic diagram of a high efficiency signaling domain.
在一个实施例中,第一字段的值为第一预设值时,第一字段的比特位可以均为1,也可以均为0,还可以部分为0部分为1,本实施例不作限定。In an embodiment, when the value of the first field is the first preset value, the bit of the first field may be all 1s, and may be all 0s, or may be partially 0. .
非直连传输帧一般可分为上行传输帧(STA至AP的帧)和下行传输帧(AP至STA的帧),现有的IEEE802.11的信令域中定义了长度为1比特的上行/下行帧指示字段,用于指示传输帧为上行传输帧,或,下行传输帧/直连传输帧,当传输帧为上行传输帧时,该指示字段的值设置为1;当传输帧为下行传输帧或直连传输帧时,该指示字段设置为0,可见,由于共用同一个0值来指示传输帧为直连传输帧或下行传输帧,因此,接收站点接收到传输帧后,无法从该指示字段识别出该传输帧为下行传输帧还是直连传输帧。而本发明实施例中,可以利用传输帧的上下行指示字段(可以为现有的上行/下行帧指示字段)和第一字段的值识别传输帧为直连传输帧还是下行传输帧,解决了上述问题。因此,在本发明实施例中,物理头还可以包括上下行指示字段,以便与第一字段的值结合起来确定传输帧为直连传输帧或下行传输帧:当上下行指示字段的值为第二预设值时(如可以取值为1),上下行指示字段的值可以指示传输帧为上行传输帧;当上下行指示字段的值为第三预设值,且第一字段的值为第一预设值或第一预设范围内的值时,上下行指示字段的值可以指示传输帧为直连传输帧或下行传输帧,第一字段的值可以指示传输帧为直连传输帧,从而可以通过上下行指示字段的值和第一字段的值指示传输帧为直连传输帧。当上下行指示字段的值为第三预设值,且第一字段的值为第二预设范围内的值时,上下行指示字
段的值可以指示传输帧为直连传输帧或下行传输帧,第一字段的值可以指示传输帧为下行传输帧,从而可以通过上下行指示字段的值和第一字段的值指示传输帧为下行传输帧。因此,可以根据物理头中的信息直接确定出传输帧为直连传输帧、上行传输帧或下行传输帧,可以提高传输帧类型的识别效率。其中,第二预设值与第三预设值是不同的值。The indirect transmission frame can be generally divided into an uplink transmission frame (a STA-to-AP frame) and a downlink transmission frame (a AP-to-STA frame), and an existing IEEE802.11 signaling domain defines a 1-bit length uplink. / downlink frame indication field, used to indicate that the transmission frame is an uplink transmission frame, or a downlink transmission frame/direct connection transmission frame. When the transmission frame is an uplink transmission frame, the value of the indication field is set to 1; when the transmission frame is downlink When transmitting a frame or directly connecting a transmission frame, the indication field is set to 0. It can be seen that since the same 0 value is shared to indicate that the transmission frame is a direct transmission frame or a downlink transmission frame, the receiving station cannot receive the transmission frame after receiving the transmission frame. The indication field identifies whether the transmission frame is a downlink transmission frame or a direct transmission transmission frame. In the embodiment of the present invention, the uplink and downlink indication field of the transmission frame (which may be an existing uplink/downlink frame indication field) and the value of the first field may be used to identify whether the transmission frame is a direct transmission frame or a downlink transmission frame, and the solution is solved. The above question. Therefore, in the embodiment of the present invention, the physical header may further include an uplink and downlink indication field, so as to determine, in combination with the value of the first field, that the transmission frame is a direct transmission frame or a downlink transmission frame: when the value of the uplink and downlink indication field is the first When the value is two, the value of the uplink and downlink indication field may indicate that the transmission frame is an uplink transmission frame; when the value of the uplink and downlink indication field is a third preset value, and the value of the first field is When the first preset value or the value in the first preset range, the value of the uplink and downlink indication field may indicate that the transmission frame is a direct transmission frame or a downlink transmission frame, and the value of the first field may indicate that the transmission frame is a direct transmission transmission frame. Therefore, the transmission frame can be indicated as a direct transmission transmission frame by the value of the uplink and downlink indication field and the value of the first field. When the value of the uplink and downlink indication field is a third preset value, and the value of the first field is a value within the second preset range, the uplink and downlink pointers
The value of the segment may indicate that the transmission frame is a direct transmission frame or a downlink transmission frame, and the value of the first field may indicate that the transmission frame is a downlink transmission frame, so that the transmission frame may be indicated by the value of the uplink and downlink indication field and the value of the first field. Downlink transmission frame. Therefore, the transmission frame can be directly determined according to the information in the physical header as a direct transmission frame, an uplink transmission frame, or a downlink transmission frame, which can improve the recognition efficiency of the transmission frame type. The second preset value is different from the third preset value.
202、发送站点发送传输帧。202. The sending station sends a transmission frame.
203、接收站点接收传输帧。203. The receiving station receives the transmission frame.
204、当第一字段的值为第一预设值或第一预设范围内的值时,接收站点根据第一字段的值确定传输帧为直连传输帧,当第一字段的值为第二预设范围内的值时,接收站点根据第一字段的值确定传输帧为非直连传输帧,并根据第一字段的值确定基本服务集的颜色或子颜色。204. When the value of the first field is the first preset value or the value in the first preset range, the receiving station determines, according to the value of the first field, that the transmission frame is a direct transmission frame, when the value of the first field is When the value is within the preset range, the receiving station determines that the transmission frame is a non-directly connected transmission frame according to the value of the first field, and determines the color or sub-color of the basic service set according to the value of the first field.
本实施例中,接收站点接收到传输帧之后,接收站点先解析传输帧的物理头,当物理头中第一字段的值为第一预设值或第一预设范围内的值时,接收站点可以根据第一字段的值确定传输帧为直连传输帧,当接收站点所在链路均为非直连链路时,表明传输帧不是发送给接收站点的传输帧,即接收站点不是传输帧的目的站点,将丢弃传输帧,不需要继续解析传输帧,可以提高传输帧的处理效率;当接收站点所在链路存在直连链路时,表明传输帧可能是发送给接收站点的传输帧,即接收站点可能是传输帧的目的站点,可以继续解析传输帧,以便进一步确定传输帧是否是发送给接收站点的传输帧。当第一字段的值为第二预设范围内的值时,接收站点可以根据第一字段的值确定传输帧为非直连传输帧,当接收站点所在链路均为直连链路时,表明传输帧不是发送给接收站点的传输帧,即接收站点不是传输帧的目的站点,将丢弃传输帧,不需要继续解析传输帧,可以提高传输帧的处理效率;当接收站点所在链路存在非直连链路时,表明传输帧可能是发送给接收站点的传输帧,即接收站点可能是传输帧的目的站点,可以继续解析传输帧,以便进一步确定传输帧是否是发送给接收站点的传输帧;第一字段可以为高效率信令域中BSS颜色字段或BBS子颜色字段,当第一字段的值为第二预设范围内的值时,即当接收站点确定传输帧为非直连传输帧时,接收站点也可以根据第一字段的值确定基本服务集的颜色或子颜色。其中,第一预设范围与第二预设范围必须无交集,且第一预设值不属于
第二预设范围,可以避免发生冲突。由于高效率信令域的比特数非常有限但是所需的指示信息又较多,所以无法提供独立的用于指示传输帧为直连传输帧的指示字段,因此本发明实施例提出与其它指示信息复用一个字段,用于指示传输帧类型为直连传输帧。虽然高效率信令域包括许多指示信息,但是用于指示传输帧为直连传输帧的指示信息与BSS Color或BSS SubColor指示信息复用同一字段时较合理。因为,直连链路站点组成的站点组可以当做一种特殊BSS,也可以当做BSS内部的一种特殊分组。故本发明实施例提出复用BSS Color或BSS SubColor字段,即采用BSS Color或BSS SubColor字段取一个或多个预设值或为某个预设范围内的值时,该字段的值用于指示传输帧为直连传输帧,而该字段在这些情况外的取值依然用于指示该字段本身具有的指示BSS Color或BSS SubColor的功能。In this embodiment, after receiving the transmission frame, the receiving station first parses the physical header of the transmission frame, and when the value of the first field in the physical header is the first preset value or the value in the first preset range, the receiving The station may determine that the transmission frame is a direct transmission frame according to the value of the first field, and when the link where the receiving station is located is a non-directly connected link, indicating that the transmission frame is not a transmission frame sent to the receiving station, that is, the receiving station is not a transmission frame. The destination station will discard the transmission frame and does not need to continue to parse the transmission frame, which can improve the processing efficiency of the transmission frame. When the link where the receiving station is located has a direct link, it indicates that the transmission frame may be the transmission frame sent to the receiving station. That is, the receiving station may be the destination station of the transmission frame, and the transmission frame may continue to be parsed to further determine whether the transmission frame is a transmission frame sent to the receiving station. When the value of the first field is a value in the second preset range, the receiving station may determine that the transmission frame is a non-directly connected transmission frame according to the value of the first field, and when the link where the receiving station is located is a direct link, It indicates that the transmission frame is not the transmission frame sent to the receiving station, that is, the receiving station is not the destination station of the transmission frame, and the transmission frame will be discarded. It is not necessary to continue to parse the transmission frame, which can improve the processing efficiency of the transmission frame; When the link is directly connected, it indicates that the transmission frame may be a transmission frame sent to the receiving station, that is, the receiving station may be the destination station of the transmission frame, and may continue to parse the transmission frame to further determine whether the transmission frame is a transmission frame sent to the receiving station. The first field may be a BSS color field or a BBS sub-color field in the high-efficiency signaling domain, when the value of the first field is a value within the second preset range, that is, when the receiving station determines that the transmission frame is a non-direct transmission At the time of the frame, the receiving station can also determine the color or sub-color of the basic service set based on the value of the first field. The first preset range and the second preset range must have no intersection, and the first preset value does not belong to
The second preset range can avoid conflicts. Since the number of bits of the high-efficiency signaling domain is very limited, but the required indication information is more, the indication field for indicating that the transmission frame is a direct transmission transmission frame cannot be provided. Therefore, the embodiment of the present invention proposes other indication information. A field is multiplexed to indicate that the transmission frame type is a direct transmission frame. Although the high-efficiency signaling domain includes a lot of indication information, it is reasonable to indicate that the transmission frame is a direct-transmission transmission indication information and the same field is multiplexed with the BSS Color or BSS SubColor indication information. Because the group of directly connected link sites can be regarded as a special BSS, it can also be used as a special grouping within the BSS. Therefore, the embodiment of the present invention proposes to multiplex the BSS Color or BSS SubColor field, that is, when the BSS Color or BSS SubColor field is used to take one or more preset values or a value within a preset range, the value of the field is used to indicate The transmission frame is a direct transmission frame, and the value of this field outside of these cases is still used to indicate the function of the field itself indicating BSS Color or BSS SubColor.
在一个实施例中,当第一字段的值为第一预设范围内的值时,即当接收站点确定传输帧为直连传输帧时,如果接收站点所在链路存在直连链路,接收站点可以通过第一字段的值进一步确定接收站点是否为传输帧的目的站点,即将第一字段的值所标识的直连链路的标识与接收站点所在的直连链路的标识进行比较,当接收站点所在直连链路的标识中存在与第一字段的值所标识的直连链路的标识匹配的标识时,表明接收站点为传输帧的目的站点,将继续解析传输帧,当接收站点所在直连链路的标识中不存在与第一字段的值所标识的直连链路的标识匹配的标识时,表明接收站点不是传输帧的目的站点,将丢弃传输帧。In an embodiment, when the value of the first field is a value in the first preset range, that is, when the receiving station determines that the transmission frame is a direct transmission frame, if the link where the receiving station is located has a direct link, the receiving The station may further determine, by using the value of the first field, whether the receiving station is the destination station of the transmission frame, that is, comparing the identifier of the direct link identified by the value of the first field with the identifier of the directly connected link where the receiving station is located, when When the identifier of the direct link that is located at the receiving station matches the identifier of the direct link identified by the value of the first field, indicating that the receiving station is the destination station of the transmission frame, the transmission frame will continue to be parsed. When there is no identifier in the identifier of the directly connected link that matches the identifier of the direct link identified by the value of the first field, it indicates that the receiving station is not the destination station of the transmission frame, and the transmission frame will be discarded.
在一个实施例中,物理头还可以包括字段集,字段集可以包括Nsts指示字段、STBC指示字段、TxBF指示字段和DCM指示字段中至少一种,当第一字段的值为第一预设值时,即当接收站点确定传输帧为直连传输帧时,如果接收站点所在链路存在直连链路,接收站点可以通过字段集进一步确定接收站点是否为传输帧的目的站点,即将字段集所标识的直连链路的标识与接收站点所在的直连链路的标识进行比较,当接收站点所在直连链路的标识中存在与字段集所标识的直连链路的标识匹配的标识时,表明接收站点为传输帧的目的站点,将继续解析传输帧,当接收站点所在直连链路的标识中不存在与字段集所标识的直连链路的标识匹配的标识时,表明接收站点不是传输帧的目的站点,将丢弃
传输帧。In an embodiment, the physical header may further include a field set, where the field set may include at least one of an Nsts indication field, an STBC indication field, a TxBF indication field, and a DCM indication field, where the value of the first field is a first preset value. When the receiving station determines that the transmission frame is a direct transmission frame, if there is a direct link on the link where the receiving station is located, the receiving station may further determine whether the receiving station is the destination station of the transmission frame through the field set, that is, the field set The identifier of the directly connected link of the identifier is compared with the identifier of the directly connected link where the receiving station is located. When the identifier of the directly connected link of the receiving station has an identifier matching the identifier of the directly connected link identified by the field set, , indicating that the receiving station is the destination station of the transmission frame, and will continue to parse the transmission frame. When the identifier of the direct link of the receiving station does not exist in the identifier of the direct link identified by the field set, the receiving station is indicated. Not the destination site of the transmission frame, will be discarded
Transfer frames.
在一个实施例中,第一字段的值为第一预设值时,第一字段的比特位可以均为1,也可以均为0,还可以部分为0部分为1,本实施例不作限定。In an embodiment, when the value of the first field is the first preset value, the bit of the first field may be all 1s, and may be all 0s, or may be partially 0. .
