In this application.
本发明涉及通信领域,特别涉及一种发送数据帧的方法及相关设备。The present invention relates to the field of communications, and in particular, to a method for transmitting a data frame and related devices.
在无线局域网(Wireless local Access Network,WLAN)中,结合图1所示,接入点(Access Point,AP)负责与多个站点(Station,STA)进行双向通信,即AP向STA发送下行数据,或者接收来自STA的上行数据。In a wireless local area network (WLAN), as shown in FIG. 1, an access point (AP) is responsible for two-way communication with multiple stations (Stations, STAs), that is, the AP sends downlink data to the STA. Or receive uplink data from the STA.
现有基于正交频分复用(Orthogonal Frequency-Division Multiplexing,OFDM)技术的无线局域网(Wireless local Access Network,WLAN)标准由逐步演进的802.11a、802.11n、802.11ac等版本组成,目前IEEE 802.11标准组织已启动了称之为高效率无线局域网(High Efficiency WLAN,HEW)的新一代WLAN标准即802.11ax的标准化工作,该标准支持正交频分复用多址(Orthogonal Frequency-Division Multiple Access,OFDMA)技术。正交频分复用多址技术将宽带信道在频域划分为多个彼此正交的子载波,并为不同的用户分配不同的子载波,从而实现多个用户的正交复用传输。The existing WLAN (Wireless Local Access Network (WLAN) standard based on Orthogonal Frequency-Division Multiplexing (OFDM) technology consists of gradual evolution of 802.11a, 802.11n, 802.11ac, etc., currently IEEE 802.11 The standards organization has initiated the standardization of 802.11ax, a next-generation WLAN standard called High Efficiency WLAN (HEW), which supports Orthogonal Frequency-Division Multiple Access (OFDM). OFDMA) technology. The orthogonal frequency division multiplexing multiple access technology divides the wideband channel into a plurality of mutually orthogonal subcarriers in the frequency domain, and allocates different subcarriers for different users, thereby implementing orthogonal multiplexing transmission of multiple users.
结合图2所示,介绍802.11ax的物理层分组结构中的数据帧,数据帧的结构包括传统短训练字段(Legacy Short Training field,L-STF)、传统长训练字段(Legacy Long Training field,L-LTF)和传统信令字段(Legacy Signal field,L-SIG)及其重复(Repeat Legacy Signal field,RL-SIG)组成的字段;之后,中间部分由高效信令字段A(High Efficiency Signal-A field,HE-SIG-A)、高效信令字段B(High Efficiency Signal-B field,HE-SIG-B)、高效率短训练字段(High Efficiency Short Training field,HE-STF)和高效率长训练字段(HighEfficiency Long Training field,HE-LTF)等字段,最后为数据字段。其中,数据字段用于数据传输,L-SIG、RL-SIG、HE-SIG-A和HE-SIG-B等字段分别用于传输不同类型的物理层信令,L-STF、L-LTF、HE-STF和HE-LTF等字段则主要用于接收端定时和频率同步、自动增益控制与信道估计等目的。如图3
所示,HE-SIG-A用来承载带宽,AP标识符等基本服务集(Basic Service Set,BSS)以及重叠基本服务集(Overlapped BSS,OBSS)内STA都会读取的信息。Referring to FIG. 2, the data frame in the physical layer packet structure of 802.11ax is introduced. The structure of the data frame includes a legacy short training field (L-STF) and a legacy long training field (Legacy Long Training field, L). -LTF) and a field consisting of a legacy signaling field (L-SIG) and its Repeat Legacy Signal field (RL-SIG); after that, the middle part is composed of High Efficiency Signal-A (High Efficiency Signal-A) Field, HE-SIG-A), High Efficiency Signal-B field (HE-SIG-B), High Efficiency Short Training Field (HE-STF) and high efficiency long training Fields such as HighEfficiency Long Training field (HE-LTF), and finally data fields. Among them, the data field is used for data transmission, and the fields such as L-SIG, RL-SIG, HE-SIG-A and HE-SIG-B are respectively used to transmit different types of physical layer signaling, L-STF, L-LTF, Fields such as HE-STF and HE-LTF are mainly used for receiving timing and frequency synchronization, automatic gain control and channel estimation. Figure 3
As shown, HE-SIG-A is used to carry information such as bandwidth, basic service set (BSS) such as AP identifier, and STAs that are read by the overlapping basic service set (Overlapped BSS, OBSS).
图2展示了AP通过下行链路(Downlink,DL)OFDMA方式利用多个资源块同时向多个STA进行数据传输。其中,几个STA还可以共享同一个资源块,通过MU-MIMO的方式,在各自的空间流上进行数据传输。此时,AP将整个带宽分为多个资源块,利用多个资源块对多个STA进行数据传输。为了让STA得知自己是否为目的STA;还需要让目的STA得知数据所在的位置以及接收数据的物理层参数,AP需要在分配资源块之前进行资源调度信息的指示,对于下行多用户传输,通常在HE-SIG-B中包含多用户的资源调度信息,指示多个STA进行数据的接收。FIG. 2 shows that an AP performs data transmission to multiple STAs simultaneously by using multiple resource blocks in a Downlink (DL) OFDMA scheme. Among them, several STAs can also share the same resource block and perform data transmission on their respective spatial streams by means of MU-MIMO. At this time, the AP divides the entire bandwidth into multiple resource blocks, and uses multiple resource blocks to perform data transmission on multiple STAs. In order to let the STA know whether it is the destination STA or not, the destination STA needs to know the location of the data and the physical layer parameters of the received data, and the AP needs to perform the resource scheduling information indication before the resource block is allocated. For the downlink multi-user transmission, The resource scheduling information of multiple users is usually included in the HE-SIG-B, and the multiple STAs are instructed to receive data.
图4是HE-SIG-B一种可能的结构,其包括公共域(HE-SIG-B common)和逐个站点域(HE-SIG-B dedicated)。公共域包含所有目的STA都需要读取的一些公共信息,如资源块分配的指示信息(Resource allocation Signaling,RASignaling),逐个站点域包含了每个STA或者在同一资源块内一组STA需要读取的调度信息。Figure 4 is a possible structure of HE-SIG-B, which includes a public domain (HE-SIG-B common) and a site-by-site domain (HE-SIG-B dedicated). The public domain contains some common information that all destination STAs need to read, such as Resource allocation Signaling (RASignaling). Each STA is included in a site-by-site domain or a group of STAs in the same resource block needs to be read. Scheduling information.
当传输带宽大于20M赫兹时,前导码部分在每个20M赫兹频段上都需要传输。对于L-STF、L-LTF、L-SIG、RL-SIG及HE-SIG-A,是在每个20M上复制传输;对于高效信令字段B部分HE-SIG-B,是采用部分复制的传输结构。以80M传输为例,前导部分的传输具体如图5所示。When the transmission bandwidth is greater than 20 MHz, the preamble portion needs to be transmitted on every 20 MHz band. For L-STF, L-LTF, L-SIG, RL-SIG, and HE-SIG-A, copy transmission is performed on each 20M; for efficient signaling field B part HE-SIG-B, partial copy is used. Transmission structure. Taking 80M transmission as an example, the transmission of the leading part is specifically as shown in FIG. 5.
可以看到,HE-SIG-B在奇数20M赫兹频段和偶数20M赫兹频段上携带不同的内容,而奇数20M赫兹频段上携带相同的内容,偶数20M赫兹频段(第二个20M赫兹频段和第四个20M赫兹频段)上携带相同的内容,如图6所示。记奇数20M赫兹频段上的HE-SIG-B为SIGB-1,偶数20M赫兹频段上的HE-SIG-B为SIGB-2。SIGB-1和SIGB-2中包含的内容,包括公共域和逐个站点域。SIGB-1包含第一个20M赫兹频段和第三个20M赫兹频段的资源指示信息(RA signaling)和在第一个和第三个20M赫兹频段上传输的用户的调度信息。SIGB-2包含第二个20M赫兹频段和第四个20M赫兹频段的资源指示信息(RA signaling)和在第二个和第四个20M赫兹频段上传输的用户的调度信息。对于20M赫兹频段的传输带宽,仅包含一个HE-SIGB(SIGB-1)。对
于40MHz的传输带宽,包含SIGB-1和SIGB-2,但SIGB-1和SIGB-2都仅包含一个20M赫兹频段上的资源分配传输结构指示和用户调度信息,SIGB-1包含第一个20M赫兹频段(奇数20M赫兹频段),SIGB-2包含第二个20M赫兹频段(偶数20M赫兹频段)。It can be seen that HE-SIG-B carries different content in the odd 20M Hz band and the even 20M Hz band, while the odd 20M Hz band carries the same content, the even 20M Hz band (the second 20M Hz band and the fourth The same content is carried on the 20M Hz band, as shown in Figure 6. The HE-SIG-B on the odd 20M Hz band is SIGB-1, and the HE-SIG-B on the even 20M Hz band is SIGB-2. Content contained in SIGB-1 and SIGB-2, including public domain and site-by-site domains. SIGB-1 contains resource indication information (RA signaling) for the first 20M Hz band and the third 20M Hz band and scheduling information for users transmitting on the first and third 20M Hz bands. SIGB-2 contains resource indication information (RA signaling) for the second 20M Hz band and the fourth 20M Hz band and scheduling information for users transmitting on the second and fourth 20M Hz bands. For the transmission bandwidth of the 20M Hz band, only one HE-SIGB (SIGB-1) is included. Correct
The transmission bandwidth at 40MHz includes SIGB-1 and SIGB-2, but both SIGB-1 and SIGB-2 contain only a resource allocation transmission structure indication and user scheduling information on a 20M Hz band. SIGB-1 contains the first 20M. In the Hertz band (odd 20M Hz band), SIGB-2 contains the second 20M Hz band (even 20M Hz band).
为记录方便,定义下面表述[1,2,1,2]代表图5、图6中HE-SIG-B传输结构中。从上往下的顺序,第一个20M赫兹频段上和第三个20M赫兹频段上传输的HE-SIG-B信息相同,记为[1,2,1,2]中第一位置和第三位置的“1”,即由“1”表示前述的SIGB-1;第二个20M赫兹频段上和第四个20M赫兹频段上传输的HE-SIG-B信息相同,记为[1,2,1,2]中第一位置和第三位置的“2”,即由“2”表示前述的SIGB-2。For the convenience of recording, the following expression [1, 2, 1, 2] is defined in the HE-SIG-B transmission structure in FIG. 5 and FIG. From top to bottom, the HE-SIG-B information transmitted on the first 20M Hz band and the third 20M Hz band is the same, recorded as the first position and the third in [1, 2, 1, 2] The position "1", that is, the "1" indicates the aforementioned SIGB-1; the second 20M Hz band and the HEM-SIG-B information transmitted on the fourth 20M Hz band are the same, denoted as [1, 2, "2" of the first position and the third position in 1, 2], that is, the aforementioned SIGB-2 is represented by "2".
然而,这种[1,2,1,2]的结构在传输过程中存在缺陷,当第一个20M赫兹频段和第三个20M赫兹频段上的用户均较多,而第二个20M赫兹频段和第四个20M赫兹频段上用户数较少时,这种结构构成的SIGB-1就会比SIGB-2大小长很多,由于HE-SIG-B的结束位置在不同的20M赫兹频段是相同的,就造成了第二个20M赫兹频段和第四个20M赫兹频段的SIGB-2传输完毕后,该频段上出现空闲,造成浪费。这种浪费是由于HE-SIG-B传输结构单一造成了,这种单一的结构不能够很好的适应不同场景下、不同负载下的HE-SIG-B的灵活分配与调度,造成了资源浪费。However, this [1, 2, 1, 2] structure has defects in the transmission process, when there are more users in the first 20M Hz band and the third 20M Hz band, and the second 20M Hz band When the number of users in the fourth 20M Hz band is small, the structure of SIGB-1 will be much longer than SIGB-2, since the end position of HE-SIG-B is the same in different 20M Hz bands. After the transmission of the second 20M Hz band and the fourth 20M Hz band of SIGB-2 is completed, idleness occurs in the band, resulting in waste. This waste is caused by the single transmission structure of HE-SIG-B. This single structure can not be well adapted to the flexible allocation and scheduling of HE-SIG-B under different scenarios and under different loads, resulting in waste of resources. .
如果根据不同20M赫兹频段上的用户数,灵活配对,做负载均衡(loadbalancing),组成SIGB-1和SIGB-2,并仍然按照[1,2,1,2]的方式传输。例如当第一个20M赫兹频段、第三个20M赫兹频段和第四个20M赫兹频段上用户数较少,而第二个20M赫兹频段上用户数较多,此时可以把第一个20M赫兹频段、第三个20M赫兹频段和第四个20M赫兹频段上的资源指示信息和传输的用户的调度信息组合成为SIGB-1,把第二个20M赫兹频段上的资源指示信息和传输的用户调度信息构成SIGB-2,按照[1,2,1,2]的传输结构,在第一个20M赫兹频段和第三个20M赫兹频段传输SIGB-1,在第二个20M赫兹频段和第四个20M赫兹频段传输SIGB-2。但是,这个传输结构存在一个问题,即在第四个20M赫兹频段的资源指示信息和传输的用户调度信息只在第一个20M赫兹频段和第三个20M赫兹频段上传输,而在第四个20M赫兹频
段上没有传输,AP无法保证第四个20M赫兹频段上的用户在第一个20M赫兹频段和第三个20M赫兹频段的信道情况如何、受干扰程度如何,即使灵活配对构成SIGB-1和SIGB-2,但仍按照[1,2,1,2]的结构传输,还是会降低了第四个20M赫兹频段上用户的性能。If it is based on the number of users in different 20M Hz bands, flexible pairing, load balancing, constitute SIGB-1 and SIGB-2, and still transmit according to [1, 2, 1, 2]. For example, when the first 20M Hz band, the third 20M Hz band, and the fourth 20M Hz band have fewer users, and the second 20M Hz band has more users, the first 20M Hz can be used. The resource indication information in the frequency band, the third 20M Hz band and the fourth 20M Hz band and the scheduling information of the transmitted user are combined into SIGB-1, and the resource indication information and the transmitted user scheduling on the second 20M Hz band The information constitutes SIGB-2, transmitting SIGB-1 in the first 20M Hz band and the third 20M Hz band according to the transmission structure of [1, 2, 1, 2], in the second 20M Hz band and the fourth The SIMB-2 is transmitted in the 20M Hz band. However, there is a problem with this transmission structure, that is, the resource indication information and the transmitted user scheduling information in the fourth 20M Hz band are transmitted only in the first 20M Hz band and the third 20M Hz band, and in the fourth 20M Hertz frequency
There is no transmission on the segment, and the AP cannot guarantee how the channel conditions of the users in the first 20M Hz band and the third 20M Hz band are affected by the interference in the fourth 20M Hz band, even if the flexible pairing constitutes SIGB-1 and SIGB. -2, but still transmitted according to the structure of [1, 2, 1, 2], or will reduce the performance of the user in the fourth 20M Hz band.
目前的HE-SIG-B的传输结构造成HE-SIG-B在超过20M赫兹频段频带上传输方式单一,无法适应实际中的多种负载情况,造成资源浪费的问题。The current transmission structure of HE-SIG-B causes HE-SIG-B to transmit in a frequency band exceeding 20 MHz, which cannot be adapted to various load situations in reality, resulting in waste of resources.

将每个频段的高效信令字段B在各自的频段上传输可以理解为,第一个20M赫兹频段的高效信令字段B需要在第一个20M赫兹频段上进行传输,这样可以满足同频传输的要求,保证用户的使用性能。The transmission of the efficient signaling field B of each frequency band in the respective frequency bands can be understood as that the efficient signaling field B of the first 20M Hz frequency band needs to be transmitted on the first 20M Hz frequency band, so that the same frequency transmission can be satisfied.

Let the length of the field B be the same or similar.
传输带宽可以为80M赫兹或160M赫兹,当采用80M赫兹时,每个频段分配20M赫兹,则可以分配四个20M赫兹频段;而采用160M赫兹时则可以分配八个20M赫兹频段,这里按照顺序可以是由上至下的顺序,即认为在读取数据帧时是按照从上至下的顺序进行读取,每一个20M赫兹的频段上都承载接入点分配额资源指示信息和用户分配信息,即对用户使用的资源进行分配,接收端通过对数据帧的解析可以得到自己所需要的资源所处位置。。The transmission bandwidth can be 80M Hz or 160M Hz. When using 80M Hz, each band is allocated 20M Hz, then four 20M Hz bands can be allocated. When 160M Hz is used, eight 20M Hz bands can be allocated. It is a top-to-bottom sequence, that is, it is considered that the data frames are read in the order from top to bottom, and each 20M Hz band carries the access point allocation resource indication information and user allocation information. That is, the resources used by the user are allocated, and the receiving end can obtain the location of the resources that need to be obtained by parsing the data frames. .

The efficient signaling field B of the frequency bands is combined, and the efficient signaling field B obtained after the combination is replicated and transmitted in the three frequency bands respectively, where the copy transmission means that the content transmitted in multiple frequency bands is the same.
根据不同的传输带宽可以分配出不同的频段个数,当传输带宽确定时,对应分配的频段个数可以确定,可以根据每个频段上资源指示信息和用户分配信息情况采用多种传输结构进行数据传输,下面针对频段的组合情况进行介绍。According to different transmission bandwidths, different number of frequency bands can be allocated. When the transmission bandwidth is determined, the number of corresponding allocated frequency bands can be determined, and data can be used according to resource indication information and user allocation information on each frequency band.

表5 160M赫兹时高效信令字段B用1比特指示信息Table 5: High-efficiency signaling field B at 160 MHz indicates that the information is 1 bit.
对于采用显式指示或隐式指示的方法与前面实施例中提到的内容相同,以及对数据帧的解析方法,可以对应参见80M赫兹采用一个比特指示高效信令字段B的传输结构的实施例,此处不进行赘述。For the method using the explicit indication or the implicit indication, which is the same as that mentioned in the previous embodiment, and the method for parsing the data frame, an embodiment of the transmission structure in which the bit efficient indication field B is indicated by 80 bits is used. It will not be described here.
作为一种可选的方案,在160MHz频段上如果出现一个或多个大于20M赫兹频段的多用户多天线传输(multi-user multiple-input multiple-output,MU-MIMO)情况,根据现有的标准,该MU-MIMO上的用户调度信息可以动态分配到该MU-MIMO所占频段的前两个20M赫兹频段上,在第一个20M赫兹频段上的用户数记为n1,在第二个20M赫兹频段上用户数记为n2,n1≥0,n2≥0,n1和n2均为整数。例如,当MU-MIMO占用40MHz并服务5个用户时,这5个用户可以动态分配到这40MHz的两个20M赫兹频段上,满足n1+n2=5。此时,n1可以看成该MU-MIMO所占用频带上第一个20M赫兹频段上的高效信令字段B的用户调度信息个数,n2可以看成该MU-MIMO所占用频带上第二个20M赫兹频段上的高效信令字段B的用户调度信息个数。接入点可以调节n1和n2,并选择表5所示的高效信令字段B传输结构做负载均衡,此时接入点分配的n1和n2个用户调度信息,这样的传输满足所选的高效信令字段B的传输结构。例如,图10所示,第一个40MHz上的两个用户STA1和STA2的调度新信息分别分配到第一个20M赫兹频段上和第二个20M赫兹
频段上,并参照[1,2,2,1,1,2,2,1]的格式重复传输。特别的,由于第一个40MHz的资源指示信息涵盖两个20M赫兹频段的资源指示信息,这个40MHz的资源指示信息可在第一个20M赫兹频段上和第二个20M赫兹频段上重复传输,并按照高效信令字段B的传输结构进行重复传输,如图10所示。可选的,该40MHz的资源指示信息可在一个20M赫兹频段上传输,在另一个20M赫兹频段上不传输。As an alternative, if one or more multi-user multiple-input multiple-output (MU-MIMO) conditions occur in the 160 MHz band, according to existing standards The user scheduling information on the MU-MIMO can be dynamically allocated to the first two 20M Hz frequency bands of the MU-MIMO frequency band, and the number of users in the first 20M Hz frequency band is recorded as n1, in the second 20M The number of users on the Hertz band is recorded as n2, n1 ≥ 0, n2 ≥ 0, and n1 and n2 are integers. For example, when MU-MIMO occupies 40 MHz and serves 5 users, these 5 users can be dynamically allocated to the two 20M Hz frequency bands of 40 MHz, satisfying n1+n2=5. At this time, n1 can be regarded as the number of user scheduling information of the high-efficiency signaling field B on the first 20M Hz frequency band occupied by the MU-MIMO, and n2 can be regarded as the second frequency band occupied by the MU-MIMO. The number of user scheduling information for efficient signaling field B on the 20M Hz band. The access point can adjust n1 and n2, and select the efficient signaling field B transmission structure shown in Table 5 for load balancing. At this time, the access point allocates n1 and n2 user scheduling information, such transmission meets the selected efficiency. The transmission structure of the signaling field B. For example, as shown in FIG. 10, the scheduling information of two users STA1 and STA2 on the first 40 MHz is allocated to the first 20M Hz band and the second 20M Hz, respectively.
Repeat the transmission in the frequency band with reference to the format [1, 2, 2, 1, 1, 2, 2, 1]. In particular, since the first 40 MHz resource indication information covers resource indication information of two 20M Hz frequency bands, the 40 MHz resource indication information can be repeatedly transmitted on the first 20M Hz frequency band and the second 20M Hz frequency band, and The transmission is repeated according to the transmission structure of the efficient signaling field B, as shown in FIG. Optionally, the 40 MHz resource indication information may be transmitted on one 20 MHz band and not transmitted on another 20 MHz band.
特别的,当出现80MHz的MU-MIMO时,接入点可以把该MU-MIMO所调度的用户分为n1和n2两部分,分派到该80MHz的第一个20M赫兹频段和第二个20M赫兹频段上分别传输,接入点可动态调节n1和n2。可选的,接入点可以调节n1和n2,并选择表5所示的高效信令字段B传输结构做负载均衡。此时,接入点分配的n1和n2个用户调度信息,传输满足所选的高效信令字段B的传输结构。例如,图11所示,第一个80MHz上的三个用户STA1、STA2和STA3的调度新信息分别分配到第一个20M赫兹频段上和第二个20M赫兹频段上,并参照[1,2,2,1,1,2,2,1]的格式重复传输。特别的,由于第一个80MHz的资源指示信息涵盖两个20M赫兹频段的资源指示信息,这个80MHz的资源指示信息可在第一个20M赫兹频段上和第二个20M赫兹频段上重复传输,并按照高效信令字段B的传输结构进行重复传输,如图11所示。可选的,该80MHz的资源指示信息可在一个20M赫兹频段上传输,在另一个20M赫兹频段上不传输。In particular, when 80 MHz MU-MIMO occurs, the access point can divide the user scheduled by the MU-MIMO into two parts, n1 and n2, and assign to the first 20M Hz band of the 80MHz and the second 20M Hz. The frequency bands are transmitted separately, and the access point can dynamically adjust n1 and n2. Optionally, the access point can adjust n1 and n2, and select the efficient signaling field B transmission structure shown in Table 5 for load balancing. At this time, the n1 and n2 user scheduling information allocated by the access point transmit the transmission structure satisfying the selected efficient signaling field B. For example, as shown in FIG. 11, the scheduling new information of the three users STA1, STA2, and STA3 on the first 80 MHz is allocated to the first 20M Hz band and the second 20M Hz band, respectively, and refer to [1, 2 The format of 2,1,1,2,2,1] is repeatedly transmitted. In particular, since the first 80 MHz resource indication information covers resource indication information of two 20M Hz frequency bands, the 80 MHz resource indication information can be repeatedly transmitted on the first 20M Hz frequency band and the second 20M Hz frequency band, and The transmission is repeated according to the transmission structure of the efficient signaling field B, as shown in FIG. Optionally, the 80 MHz resource indication information may be transmitted on one 20 MHz band and not transmitted on another 20 MHz band.
本实施例中采用的是[1,2,1,2,1,2,1,2]和[1,2,2,1,1,2,2,1]两种可选传输结构的高效信令字段B传输结构。可选的,本实施可采用[1,2,1,2,1,2,1,2]和以下10种传输结构中的一种:[1,2,2,1,1,1,2,2],[1,2,2,1,1,2,2,1],[1,2,2,1,2,1,1,2],[1,2,2,1,2,1,2,1],[1,2,2,1,2,2,1,1],[1,2,1,2,1,1,2,2],[1,2,1,2,1,2,2,1],[1,2,1,2,2,1,1,2],[1,2,1,2,2,1,2,1],[1,2,1,2,2,2,1,1]。此时,在发送端指示表格中,即表5,传输结构2即改为上述10种传输结构中的一种。In this embodiment, the efficiency of two optional transmission structures [1, 2, 1, 2, 1, 2, 1, 2] and [1, 2, 2, 1, 1, 2, 2, 1] is adopted.
