具体实施方式
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。

S220，根据该资源调度信息如果包含存在缺省的资源块分配信息的指示，且该接收端需要根据缺省的资源块分配信息进行传输，则按照协议约定或者双方约定的方式进行传输。
对于默认STA，其接收与发送流程相应的一致；而对于非默认STA，可以无需进行接收，不可以进行发送。
该方法100可以应用于各种通过资源调度的方式实现多用户传输的通信系统，例如，采用OFDMA或MU-MIMO等方式进行通信的系统。
并且，该方法100可以应用于无线局域网(WLAN，Wireless Local Area Network)，例如，无线保真(Wi-Fi，Wireless Fidelity)等。
图2是WLAN系统示意图。如图2所示，该WLAN系统包括一个或多 个接入点AP21，还包括一个或多个站点STA22。接入点和站点之间进行数据传输，其中站点根据接入点发送的前导码确定被调度给自身的资源，基于该资源与接入点之间进行数据传输。
可选地，该发送端为网络设备，该接收端为终端设备。
具体地说，作为发送端设备，可以列举通信系统中的网络侧设备，例如，可以是WLAN中的接入点(AP，Access Point)，AP也可称之为无线访问接入点或桥接器或热点等，其可以接入服务器或通信网络。
作为接收端设备，可以列举通信系统中的终端设备，例如，可以是WLAN中的用户站点(STA，Station)，STA还可以称为用户，可以是无线传感器、无线通信终端或移动终端，如移动电话(或称为“蜂窝”电话)和具有无线通信功能的计算机。例如，可以是便携式、袖珍式、手持式、计算机内置的，可穿戴的，或者车载的无线通信装置，它们与无线接入网交换语音、数据等通信数据。
应理解，以上列举的适用本发明实施例的方法100的系统仅为示例性说明，本发明并不限定于此，例如，还可以列举：全球移动通讯系统(GSM，Global System of Mobile communication)，码分多址(CDMA，Code Division Multiple Access)系统，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)，通用分组无线业务(GPRS，General Packet Radio Service)，长期演进(LTE，Long Term Evolution)系统。
相应地，网络设备可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，可以是微小区基站，可以是微基站(Micro)，可以是微微基站(Pico)，可以是家庭基站，也可称为毫微微蜂窝基站(femto)，本发明并不限定。终端设备可以是移动终端(Mobile Terminal)、移动用户设备等，如移动电话(或称为“蜂窝”电话)。
WLAN系统中关于资源块大小划分的规则为：最小的资源块包括26个子载波。除此之外，包括52个子载波，106个子载波，242个子载波，484个子载波，996个子载波的资源块。相应的，较大的资源块可以看作26个子载波的最小资源块的2倍，4倍，9倍，19倍，38倍。
如图3所示802.11ax一种可能的数据结构，AP将整个带宽分为多个资源单元(子带)，利用多个资源单元对多个STA进行数据传输。为了让STA 得知自己是否为目的STA，以及，让目的STA得知数据所在的资源块位置以及接收数据的物理层参数，AP需要在传输数据之前进行资源调度信息的指示。通常，在HE-SIG-B中包含多用户STA的资源调度信息，指示多个STA进行数据的接收。
图4是HE-SIG-B一种可能的结构，其包括公共域(common part)和逐个站点域(dedicated part)。其中公共域包含所有目的STA都需要读取的一些公共信息，如数据部分的保护间隔(Guard Interval,GI)，资源块或者资源单元分配的位置信息，需要发送的HE-LTF(High Efficient Long Training Field，高效长训练序列)的OFDM符号数目等；而在逐个站点域包含了每个STA或者在同一资源块内一组STA需要读取的信息，其中包含站点标识(STA Identifier,STA ID)，调制与编码策略(Modulation and Coding Scheme；简称：MCS)用于指示调制与编码策略，空时流数(Number of Space-Time Stream；简称：NSTS)用于指示使用的空时流个数，低密度奇偶校验码(Low Density Parity Check；简称LDPC)用于指示是否使用LDPC编码方式；空时分组编码(Space Time Block Coding；简称：STBC)为用来指示是否采用STBC；波束成形(Beamforming,BF)用于指示是否采用了波束成形技术。除此之外，还可以包括循环冗余码(Cyclic Redundancy Code；简称：CRC)用来保存CRC校验比特；尾部比特(Tail)用来存放二进制循环卷积码(Binary Convolution Code；简称：BCC)的6个比特的尾部。
如图4，资源块位置信息除了可以放在在公共域内之外，还可以针对每个STA分别指示其资源块的位置。也就是说，可以仅在公共域内包含资源块位置信息，或者仅在站点域部分包括资源块的位置，或者，可以在公共域和站点域都包含有资源块的位置相关的信息。其具体的指示方式本文不做限制。
实施例一
目前，存在有多种资源块位置的指示方式，一种较为高效的方式是把所有可能的组合存在一张表里，用索引指示各个资源块分配的情况。在802.11ax中，目前定义了多种资源块的大小，按照子载波的个数分为26,52,106,242,484,996等。其中26个子载波大约对应2MHz，52个子载波大约对应4MHz，106个子载波大约对应10MHz，242个子载波大约对应20MHz，484个子载 波大约对应40MHz，996个子载波大约对应80MHz。但又并非完全对应，举例来讲，当带宽为80MHz时，会存在4个242个子载波的大资源块，除此之外，在中间部分还会存在一个26个子载波的小资源块。
图5是针对20MHz的总带宽的可能的OFDMA资源块的组合方式，对于20MHz，资源块的大小可能为26,52,106(由于之前采用的是102，因此图3中由102代表106)，一共有25种情况，对应25个序列索引，然后只需要在公共部分携带ceil(log225)＝5比特就可以携带20MHz所有可能的情况，其中ceil表示向上取整。对于总带宽为40MHz，80MHz，160MHz的情况，同样可以列举出所有可能的情况，进行列表索引，最后通过若干比特指示所有可能的情况。当然，针对总带宽为40MHz，80MHz，160MHz的情况，还可以对每个20MHz分别进行列表索引，分别进行指示。
另外，参考图6，在OFDMA位置分配时，也可能同时考虑多用户MIMO(Multiple-user MIMO,MU-MIMO)传输，即在某个子带中进一步进行空间流上的多用户分配。例如，当资源块足够大，如106或者242个时，会允许进一步利用MU MIMO在该子带进行传输。此外，还有未占据所有资源块的情况，即有些资源块空着，没有进行数据的传输。同时考虑了以上两种情况，有一种包含更加全面的分配方式的表格索引，与前一种相比，需要更多的比特进行指示。其中标有1-8的资源块为满足传输MU-MIMO的情况，会针对1个用户至8个用户的每一种情况分别对应一个索引。
当然，与图5中提到的方案类似，针对图6所示的方案，针对总带宽为40MHz，80MHz，160MHz的情况，同样可以列举出所有可能的情况，进行列表索引，也可以对该总带宽中的每个20MHz分别进行列表索引，分别进行指示。
在本发明提供的实施方式中，通过列表索引的方式进行缺省的资源分配信息的指示。资源分配信息可以参考表格索引的方式，例如前面的图5、图6所示，其中包括一个或者多个用于指示缺省的资源分配信息的索引。
前述缺省的资源分配信息包括：
1)、缺省的资源块的划分的情况。举例来讲，AP与STA约定或者协议规定的资源块的划分是，若带宽为40MHz，则将整个带宽分为两个242个子载波的资源块；若带宽为80MHz，则将整个带宽分为四个242个子载波 的资源块及一个26个子载波的资源块。或者，按照前序传输的资源块的划分情况，确定当前传输的资源块的划分情况，例如前序的上行传输时20MHz分为了9个26个子载波的资源块，则在下行传输时采用与前序上行传输时相同的资源块划分方式，同样为9个26个子载波的资源块。或者，
2)、缺省的资源块的目的STA(资源块上分配的STA)。即，参与前序传输的STA按照预先规定的模式在该资源块接收/发送数据。举例来讲，对于参与了前序传输的STA，会按照在本次传输中与前序传输相同的资源块内或者前序传输的资源块所属的242个子载波的资源块内接收/发送数据。除此之外，也可以之前通过信标(Beacon)帧或者某种管理帧预先规定好哪些STA要在哪些资源块内接收/发送数据。或者，
3)、作为一种特殊情况，缺省的确认帧的回复方式。其中包括资源块如何分配，确认帧在哪些资源块上发送，以及由哪些STA发送确认帧。其中，3)包含了1)和2)中需要默认指示的内容，除此之外，3)中还可以包括利用什么方式回复什么MAC帧类型的确认帧，例如O-BA,M-BA,OFDMA M-BA及BA。
具体的，实施例一里的索引不单单指示资源块的划分的情况,而是包含资源块的划分的情况和资源块的目的STA的信息。具体的，包括两种，第一种是：针对待分配的总带宽，该索引用于同时指示资源块的划分以及每个资源块的目的STA是否为默认的STA；第二种是：资源块划分的情况采用某种已知或者其他的方式进行指示，该索引用于指示每个资源块内分配的目的STA是否为默认的STA。
针对第一种的一个特例为，该索引用于指示缺省的确认方式，即限定资源块中承载的是某种MAC类型的确认帧。
除此之外，在发送关于缺省的资源分配信息的指示之外，也可以先指示示单播帧还是组播帧，再进一步指示组播帧的目的STA。
缺省的资源分配信息可以为以上几种默认分配方式中的某一种；也可以针对每一种分别指示，分别建立索引。在具体实施的过程中，各个索引及其对应的资源分配情况、以及目标站点等情况可以分别存储于发送端或者接收端，或者采用其他的方式为发送端和接收端共知。
一个例子中，如图11a，多个STA按照触发帧的调度进行了上行多用户传输帧的发送；在AP进行下行确认帧的回复时，资源块分配指示索引为26 (仅为举例可以是别的值)，该资源块的分配将按照图7中所示进行分配，分为两个242个子载波的资源块。然后利用242个子载波的资源块对前序在242个子载波范围内传输了上行数据的STA进行M-BA帧的确认。
如图11b，另一个例子中，若资源块分配指示索引为27(仅为举例可以是别的值)，资源块分配将按照图8a中的情况进行分配，资源块的分配与前序上行数据传输的资源块分配相同，若前序的某个子带为单个STA的数据传输，则回复O-BA；若前序的某个子带为多个STA的MU MIMO的数据传输，则回复M-BA。
另一个例子中，资源块分配指示索引为28(仅为举例可以是别的值)，则如图10a，默认逐个站点指示当中排在第K个资源指示的资源块中所包含的是M-BA帧。资源块分配指示索引为29(仅为举例可以是别的值)，如图9，则默认回复的方式针对需要回复确认帧的STA数进行资源块的平均分配，然后在每个资源块内回复O-BA。
对于这种实施方法，同样适用于触发帧中上行调度信息资源块分配的指示，指示下行帧中被索取立即确认帧的目的STA按照默认的资源块分配在相应的资源块上进行上行确认帧的发送。
图11a、图11b所示的两种情况为针对整个带宽进行缺省的资源分配信息指示的方法，即索引的值用于指示同时包含了资源块的划分与目的STA是否为默认STA的缺省的资源分配信息。
此外，如图11c所示，可以针对每个资源块分别指示。例如，只针对资源块较大的情况(大于阈值106或者242个子载波的资源块)才传输组播数据，其中，针对该资源块传播的MU MIMO用户数的每一种情况分配一个索引值。其中图11c所示为简化的表示，第1行实际上相当于集中的表示了81行，对应81个索引值，分别为N1-N81，其中左右两个106(1～9)分别表示该位置的大小为106的资源块分配给1～8中任意一个数量的用户，第9种情况用于指示该资源块的目的STA为默认的STA，或者，用于指示该资源块上传输组播帧。从图11c可以看到，索引值一方面指示了资源块的分配情况：106的资源块、26的资源块、106的资源块，另一方面指示了某个特定资源块的目的STA是否是默认的STA。
图11d给出了图11c一种展开的标识方法，其中索引N90表示20MHz被按顺序分为106,26,52,52四个资源块，第一个大小为106的资源块的目的 STA为默认的STA，索引N99表示20MHz被作为1个完整的242个子载波的资源块，且其目的STA为默认的STA。
MU MIMO用户数为1～8中的任意一个值，在本实施方式中，还可以包含另一个索引值，相当于，例如针对较大资源块的第9种情况，用于指示该资源块的目的STA为默认的STA，例如，前序发送上行信息的站点。
此外，如图11c所示，针对每个资源块，还可以指示该资源块传播的是组播帧。关于组播帧的目的STA，可以通过限制只允许传输一个组播MAC帧，且参与单播接收的STA无需接收组播帧来完成。这样STA得知自己并未参与单播传输时，可以进行组播帧的读取，通过读取MAC地址或MAC帧体的STA ID来识别自己是否为该组播的目的STA。还可以通过携带特殊的多播ID，来指示是有固定分组的组播帧或者是临时分组的组播帧。或者，可以针对较大的资源块，第10种情况，相应的索引值用于指示该资源块传输的MAC帧为参与前序上行传输的STA才需要读取的MAC帧(临时分组的)，相应的，对于第9种情况的相应的索引值用于指示固定分组的组播传输。
前面提到的临时分组的组播传输中，多个目的STA(不一定是小区中的全部STA)没有共同的组播MAC地址(非广播MAC地址)来识别这一组STA。例如，任意调度的多个参与上行多用户传输的STA，对于这些STA，若采用M-BA方式回复，则M-BA的多个目的STA往往并没有共同的组播MAC地址。固定分组的组播传输中，有MAC层以上分配的共同的组播MAC地址，可以用于识别固定分组的组播传输的目的STA。
实施例一中，通过更多缺省的资源分配信息的索引的值来进行单播/组播数据的指示和、或者默认确认方式的指示。进行了公共部分的指示后，还可以针对每个STA或者针对每个资源块内的STA组(MU MIMO用户组或者组播传输用户组)分别进行物理层的资源调度参数的指示。由于在公共部分已经得知了每个资源块传输的MAC帧为单播/组播，若为单播数据，是单个STA还是一个MU MIMO用户组，所以逐个站点域可以针对每个资源块内传输方式的不同特别设计资源指示的方式。举例来讲，对于缺省的资源分配信息指示的资源块，可以不进行其资源块上分配的站点的STA ID的指示。对于组播传输，由于要保证边缘用户接收的鲁棒性，因此往往采用较低的MCS 以及单个数据流，因此可以采用缺省的资源分配信息进行组播数据的传输，而无需指示相关的物理层参数，如MCS,NSTS,LDPC,STBC,BF等。因此一种可能的方式是针对默认传输的组播数据，无需进行逐个站点域的指示而完全采用缺省的资源分配信息。若指示的缺省的资源分配信息为后续所有的资源块均采用缺省的资源分配信息，则可不进行逐个站点域的指示，而只进行公共域的指示。
对于STA侧，当STA读取资源分配指示时，读取的资源分配指示的索引为一种缺省的资源分配信息，且自己参与了前序的传输，则按照缺省的资源分配信息进行资源块的读取/发送；若没有参与前序的传输，则不继续读取/发送。
关于缺省的确认方式
前述实施方式中提到的缺省的资源分配信息的一个特例是缺省的确认方式。缺省的确认方式有多种，各实施方式对其不做限制。
例如，一种默认的确认帧回复方式1，如下图7所示的默认的回复方式。即对于所在20MHz内(242子载波资子带)进行上行传输的STA，AP在对应的子带利用M-BA的方式对齐回复。而针对不同20MHz上的M-BA，通过OFDMA的方式进行M-BA的传输。
又例如，一种默认的确认帧回复方式2，为资源分配与前序资源块相同的OFDMA BA(O-BA)传输。此外，若某个资源块为MU-MIMO传输，则可在对应的资源块上回复M-BA或者继续平均分配该资源块进行O-BA传输，如图9所示。
又例如，一种默认的确认帧回复方式3，为平均分配整个带宽的O-BA回复方式。为了平衡各个子带回复确认帧的开销，对整个带宽按照STA的数目平分，进行O-BA的回复，如图9所示。
又例如，一种默认的确认帧回复方式4，为逐个站点域(Dedicated part)第K个指示传的是默认的组播帧，且目的STA为前序参与了UL MU传输的STA，其他资源块由后续部分继续规定，可以传输单播帧或者有固定分组的多播帧。优选地，此情况适用于公共部分和逐个站点部分联合编码的情况。如图10a所示，默认第一个指示传的是默认的组播帧M-BA，资源块的位置可以指示，也可以默认。
以上几种默认的确认帧回复方式即包含了资源块划分的缺省的资源分配信息，同时包含了在各个资源块内的目的STA为默认STA。当然，在其他的实施方式中，也可以只包含资源块的划分，比如指示资源块的划分是按照以上4种方式的划分方法，但是每个资源块的目的STA再分别单独指示；也可以先进行资源块的划分，再在每个资源块里指示目的STA是不是默认STA。
关于缺省的资源块的目的STA(参与前序传输的STA)
前面提到缺省的(默认的)资源块的目的STA可以是参与前序传输的STA，或者，基于信标帧和管理帧提前约定好的STA。
除了下行多用户传输，802.11ax中还引入了多用户上行传输，如图12所示。AP发送触发帧，该触发帧用于触发多用户传输，并包含多用户上行传输的资源调度信息。多个STA接收触发帧之后，根据触发帧中的资源调度信息，几乎在同一时间内发送上行帧。AP收到多用户的上行帧之后为多个STA同时发送多用户确认帧。
具体的，AP发送trigger帧，需要STA在X帧间距(X Inter-frame Space)之后立即传输上行帧，并设定确认规则(Acknowledge Policy)，若设确认规则为立即反馈，则要求AP在正确接收数据XIFS之后立即回复确认帧。对于确认帧来讲，“参与了前序传输的STA”即参与了上行帧发送的STA。除此之外，对于参与了前序传输的STA需要在哪个子信道接收数据取决于默认的资源分配的情况。
若AP向多个STA发送下行多用户帧，并设定确认规则为立即反馈，则STA在正确接收数据XIFS之后需要立即回复确认帧。而AP在发送下行数据的同时会发送触发帧，传递用于触发确认帧的调度信息，指示STA如何回复确认帧。则对于触发帧中的调度信息中所指的“参与了前序传输的STA”，是说当前下行传输中索取立即回复的的下行帧的目的STA，如图10b所示。
若索求了确认帧的AP/STA在一段固定时间内没有收到/正确接收相应的确认帧，则认为数据没有正确接收，或者没有解对确认帧，则不再认定自己为参与了前序传输的STA。
实施例二
利用特殊的STA ID进行默认的资源指示
参考图13，在以图4所示为例的资源分配信息的基础上，除资源块位置信息的指示(具体方式不做限定)之外，采用特殊的STA ID指示在某个资源块内的MAC帧的一个或多个目的STA为前序参与上行传输的STA。而没有参与前序上行传输的STA则无需读取该资源块。其中特殊的STA ID可以为全0或者全1的STA ID，或者AP与参与前序传输的STA提前约定好的STA ID。
STA读取STA ID,若STA ID为特殊的STA ID，且该STA参加了前序对应资源块上的上行传输，则读取该资源块内的MAC帧；若该STA没有参与前序对应资源块上的上行传输，则无需读取该资源块。其中对应资源块可以为上行传输与该资源块相同的资源块或者属于相同的20MHz(242个子载波的资源块)。
此外，也可以利用特殊的STA ID去指示本资源块内的MAC帧为组播MAC帧还是单播MAC帧。
当然，进一步的，参考图14，可以预留两种特殊的STA ID，当STA读到特殊的STA ID 1，则认为是参与了前序对应资源块的上行传输的STA才需要读取；而读到了特殊的STA ID 2，则认为该帧是一个固定分组的组播帧，并按照某些规则进行选择性的读取。如果不是两种特殊的STA ID，若规定参与了单播帧的STA无需读取组播帧，则根据是否有发给自己的单播帧，决定是否进行读取。若STA支持单播数据和组播数据的同时接收，则可以共同进行读取。
需要补充说明的是，对于MAC(Media Access Control，媒体接入控制)帧传输方式，存在单播传输(unicast)，多播传输(multicast)以及广播传输(broadcast)，其中多播传输与广播传输又统称为组播传输(Groupcast)。单播是指封包在计算机网络的传输中，目的地址为单一目标的一种传输方式。它是现今网络应用最为广泛，通常所使用的网络协议或服务大多采用单播传输，例如一切基于TCP的协议。除单播传输方式外，还有广播和多播。它们与单播的区别是，广播的目的地址为网络中的全体目标，而多播的目的地址是一组目标，加入该组的成员均是封包的目的地。这里与前文单用户传输的数 据和多用户传输的数据并不相同。通过多播进行视频传输/授课内容传输是802.11ax中一种重要的应用场景，在运动场馆，阶梯教室中将会广泛应用。
实施例三
利用特殊的组播ID进行缺省的资源分配信息的指示
参考图15，在以图4所示为例的资源分配信息的基础上，除资源块位置信息的指示(具体方式不做限定)之外，还包括单播或者组播的指示，以及，针对组播，采用特殊的组播ID指示该组播不是通常的享有共同组播MAC地址的组播帧，而是需要默认的STA去读取的组播帧。
其中，单播和组播数据的指示可以采用实施例一中提到的利用资源块位置信息的索引进行指示，或者其他的方案进行指示，本发明方案不作限制。其他的指示单播和组播的方案例如，通过1比特明示或者特殊的STA ID暗示某个资源块上的MAC帧为多播/广播MAC帧(组播)，还是单播MAC帧。若通过1比特指示某个资源块的MAC帧为多播/广播MAC帧，还可以通过组播ID进一步指示是哪一个多播组。
其中组播ID可以由STA与AP通过握手协商的方式同组播MAC地址对应起来。
相应的，在接收侧，STA可以通过读取接收到的信息，确认某些资源块传播的MAC帧是组播MAC帧还是单播MAC帧。STA区分某资源块内的MAC帧是多播帧之后，读取组播ID，发现组播ID为特殊的组播ID，且该STA参加了前序对应资源块上的上行传输，则按照缺省的资源分配信息接收组播数据，或者，读取该资源块内的MAC帧；若该STA没有参与前序对应资源块上的上行传输，则无需读取该资源块。
对于实施例二和三，需要指出，STA ID或组播ID也可以通过加扰或者异或的方式隐式携带，接收端通过利用特殊的ID进行解扰或者反异或来识别AP是否隐式携带了特殊ID，对于此种方法仍然在本发明方案考虑的范围内。
实施例四
利用单用户分组结构进行缺省的资源分配信息的指示
802.11ax中有三种不同的分组结构，而对于单用户分组结构，只需要进行单个STA的资源指示，因此无需传输HE-SIG-B，节省了HE-SIG-B的开销。因此实施例四首先指示该分组结构为单用户分组结构，其中指示方式可以通过HE-SIG-A中显示指示，也可以通过L-SIG+RL-SIG部分隐式携带，本发明方案不作限制。接着，通过特殊的STA ID或者特殊的组播ID指示该分组结构的带宽是按照缺省的资源分配信息进行的资源块分配，并且所有的资源块内的MAC帧的目的STA都为默认STA，即参加了前序上行传输的STA。特殊的组播ID是当确认该地址为组播ID时特殊的ID，如全0或全1，或者AP与STA预先规定好的ID。
对于该种方式，可以利用单个站点的物理层参数对多个资源块内的MAC帧进行统一的指示，其中物理层参数，如图16所示，可以包括MCS,NSTS,LDPC,或者STBC等；也可以直接采用默认的物理层参数而不进行指示，比如MCS固定采用MCS0，NSTS固定采用1个空间流，LDPC固定设为0，即采用BCC的方式，STBC固定设为0，即不采用STBC的方式。
STA读取该帧为SU的帧，且STA ID/组播ID为特殊的STA ID/组播ID，且该STA参加了前序的上行传输，则按照缺省的资源分配信息读取该资源块内的MAC帧；若该STA没有参与前序的上行传输，则无需读取该资源块。读取HE-SIG-A中SU的物理层参数或者按照默认的物理层参数进行MAC帧的读取。
实施例五
利用信息比特进行缺省的资源分配信息的明示指示
通过在L-SIG和RL-SIG中进行隐式携带的比特或者在HE-SIG-A或者HE-SIG-B中利用信息比特直接进行缺省的资源分配信息的指示。可以针对整个带宽直接进行1比特的指示，指示采用某种缺省的资源分配信息；也可以对多种缺省的资源分配信息分别指示。此外，也可以在以图4所示为例的资源分配信息的基础上，除资源块位置信息的指示(具体方式不做限定)之外针对每个资源块分别利用1比特进行指示。举例来讲，通过1比特指示确认方式为某种缺省的资源分配信息，即资源块按照某种缺省的资源分配信息 分配，且目的STA为参与了前序上行传输的STA。
对于STA侧，STA读取在L-SIG和RL-SIG或HE-SIG-A或HE-SIG-B中的缺省的资源分配信息比特指示，若指示位缺省的资源分配信息读取，且该STA参加了前序的上行传输，则按照缺省的资源分配信息读取该资源块内的MAC帧；若该STA没有参与对应上行传输，则无需读取该资源块。
实施例六
通过不传输STA ID进行缺省的资源分配信息的指示
AP通过不传输逐个站点域或在逐个站点域不携带STA ID的方式来进行缺省的资源分配信息的指示。而对于STA侧，会通过对比HE-SIG-B的符号数来推算出是否包含逐个站点域或者逐个站点域部分是否携带STA ID，从而得知是否进行了缺省的资源分配信息的资源指示。
在HE-SIG-A中会携带HE-SIG-B的符号数指示。而HE-SIG-B中公共部分所占据的OFDM符号数一般来说是固定的。可以通过符号数指示HE-SIG-B部分只包含公共部分而不包含逐个站点部分，即HE-SIG-A中指示的HE-SIG-B的符号数等于公共部分的符号数；此外，还可以通过公共部分的信息进行HE-SIG-B符号数的计算，来指示逐个站点字段不包含STA ID。举例来讲，若：
Figure PCTCN2015083617-appb-000001
，则说明逐个站点域不包含STA ID，通过不包含STA ID的方式来隐含指示后续传输的MAC帧的目的STA为默认的STA，即参与了前序上行传输的STA。
其他发明实施例
此外，针对HE-SIG-B公共部分与逐个STA指示部分的某一个STA/MU MIMO用户组/组播用户组的指示联合编码，并利用标识信息进行加扰的情况，可以通过L-SIG和RL-SIG或HE-SIGA中携带比特，指示数据部分存在组播传输，且组播传输的资源指示的顺序可以为默认的位置(例如，假设永远为逐个站点域指示的第一个)或者通过信息比特进一步指示组播传输指 示的顺序(指示为第K个)。当STA得知所有逐个站点域指示的第几个为组播传输时，则可以利用组播ID或者特殊的组播ID去解扰，简化了STA的接收流程。当STA得知某个位置上传输的MAC帧为组播帧时，可以进一步利用实施例一中所述的方法进一步区分组播帧的目的STA。
对于此种情况，STA读取L-SIG和RL-SIG或HE-SIG-A中的组播信息比特指示，若指示数据部分存在组播数据传输，则在默认的位置或者所指示的位置利用特殊的ID进行解扰。

11.STA读取该帧为SU的帧，且STA ID为特殊的STA ID，且该STA为默认STA，则按照默认的资源块分配读取相应资源块内的数据；若该STA不是默认STA，则无需读取该资源块内的数据。此外所有的组播帧采取统一的物理层参数或者默认的物理层参数。
12.STA读取在L-SIG和RL-SIG或HE-SIG-A或HE-SIG-B中的比特指示，若指示为缺省的资源分配信息读取，且该STA为默认STA，则按照默认的资源块分配或明确指定的资源块分配读取相应资源块内的数据；若该STA为非默认STA，则无需读取该资源块内的数据。
