Description

一种无线局域网中的信息传输方法、装置及系统 技术领域
本发明涉及通信领域，尤其涉及一种无线局域网中的信息传输方法、装置及系统。
背景技术
随着通信技术的发展，用户需求日益增加，为提高网络吞吐量，提高信息传输效率，以WLAN(Wireless Local Area Networks，无线局域网)网络为例，在WLAN网络中，上行多用户技术可以同时向多个站点传输数据，提高了信息传输的效率。例如，可以通过OFDMA(Orthogonal Frequency Division Multiple Access，正交频分多址)技术或者MU-MIMO(Multi-User Multiple-Input Multiple-Output，多用户多入多出)技术实现。
在利用上行多用户技术同时向多个站点传输数据时，例如，可以传输数据帧，管理帧，控制帧，WLAN网络中的AP(Access Point，接入点)为每个用户分配具有相同时长的资源块，但不是每个站点都可以将分配的资源块全部使用，会使得不同站点接收信息的结束时刻可能会不对齐，为了使得每个站点接收信息时在时间上对齐，如图1所示，当某个站点没有将上行时间完全占用时，通过填充非数据信息使得每个站点接收信息时在时间上对齐。但是，这导致系统传输了没有用的非数据信息，浪费了资源。

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，所描述的实施例仅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。
本发明实施例提供一种无线局域网中的信息传输方法，优选的，应用于WLAN网络中，可以在OFDMA技术或者MU-MIMO技术中实现，参照图2所示，图2示出了一种WLAN网络的结构，该WLAN网络20包括AP201及STA(站点)202，多个STA202可以与同一个AP201进行通信，实现上行多用户技术。本发明实施例提供的无线局域网中的信息传输方法参照图3所示，包括以下步骤：
301、接入点向至少两个站点发送控制信息。
控制信息是至少两个站点共用的。至少两个站点根据共用的控制信息可以确定出的相同的传输速率并向接入点发送上行帧。优选的，接入点可以是图2所示的WLAN网络20中的AP201，至少两个站点可以是至少两个STA202。优选的，接入点可以通过广播的方式向至少两个站点发送控制信息，控制信息可以触发至少两个站点同时发送上行帧，当然，此处只是举例说明，并不代表本发明局限于此。
可选的，控制信息还包括帧模式信息，帧模式信息用于指示至少两个站点发送上行帧时采用的帧模式；接入点在生成控制信息之前，还可以确定帧模式并生成帧模式信息。此处，需要说明的是，上行帧中一部分控制帧是具有固定长度的，例如ACK(Acknowledgement，肯定应答)帧、CTS(Clear To Send，清除发送)帧等。也有一部分帧具有不同的模式，不同的模式对应不同的长度。例如BA(Block Acknowledgement，基础块确认)帧具有四种不同的帧模式，分别是：基础块确认(Basic Block Acknowledgement)帧长度为130字节，1字节为8比特、压缩块确认(Compressed Block Acknowledgement)帧长度为10字节、多业务标识符块确认(Multi Trafic Identifier Block Acknowledgement)帧长度为12×m字节，m为TID(Trafic Identifier，业务标识符)的个数，扩展的压缩块确认(Extended Compressed Block Acknowledgement)帧长度为11字节。此时，接入点可以确定帧模式，使得至少两个站点均采用相同的帧模式传输上行帧，需要说明的是，此处ACK帧作为BA帧的一种帧模式存在。当然，此处只是举例说明，并不代表本发明局限于此。
可选的，站点的传输速率可以通过设备的MCS(Modulation and Coding Scheme，调制编码策略)、带宽、公共NSTS(Number of Space Time Streams，公共空时流数目)、公共STBC(Space Time Block Coding，公共空时块编码)等参数确定。控制信息可以包含至少两个站点的公共MCS、公共带宽、公共NSTS、公共STBC中的至少一项。这样，至少两个站点就可以根据控制信息确定相同的传输速率发送上行帧。需要说明的是，至少两个站点的公共MCS、公共带宽、公共NSTS、公共STBC都可以包含在控制信息中发送至该设备，也可以是预先设定的，不需要通过控制信息发送。例如，可以预先设定至少两个站点都采用最低的MCS调制，此时，接入点不需要确定至少两个站点的MCS，控制信息中也不需要包含至少两个站点的MCS，当然，此处只是举例说明，并不代表本发明局限于此。
可选的，控制信息包括元素字段指示，元素字段指示用于指示至少两个站点发送的上行帧包含的元素字段。
元素字段是WLAN系统中管理帧中采用的一种通用结构。一个元素字段通常包括三部分：元素识别(Element Identification)字段、长度(Length)字段、信息(Infomation)字段。其中元素识别字段为1个字节(Octet)，用于标识该元素字段的类型；长度字段为1个字节，用于标识该元素字段的长度；信息字段用于承载该元素字段的内容。本实施例中的元素字段包含元素识别字段。
在一种应用场景中，接入点可以为至少两个站点分配子信道数目。具体的，接入点确定至少两个站点的子信道数目或信道数目，至少两个站点的子信道数目或信道数目为至少两个站点向接入点发送上行帧时所占用的子信道数目或信道数目。需要说明的是，通常情况下，一个信道占用20MHz(兆赫兹)的带宽，子信道是组成信道的单元，一个信道包含多个子信道。
或者，可选的，如果接入点并没有指定至少两个站点发占用的子信道数目或信道数目时，至少两个站点中每个设备可以在接收接入点发送的下行数据时所占用的至少一个子信道中的每个子信道上发送 上行帧，或者，每个设备在接收接入点发送的下行数据时所占用的至少一个信道中的每个信道上发送上行帧。即在每个子信道或每个信道上发送一次上行帧。
可选的，控制信息位于下行帧的PL(Physical Layer，物理层)的HE-SIG(High Efficiency Signal field，高效率的信令字段)，或者控制信息位于下行帧的MAC(Media Access Control，媒体访问控制)层。如图4所示，下行帧还可以包含L-STF(non-High Throughput Short Training field，非高吞吐率的短训练字段)、L-LTF(non-High Throughput Long Training field，非高吞吐率的长训练字段)、L-SIG(non-High Throughput Signal field，非高吞吐率的信令字段)、HE-STF(High-Efficiency Short Training field，高效率的短训练字段)、HE-LTF(High-Efficiency Long Training field，高效率的长训练字段)等。
302、接入点接收至少两个站点基于共用的控制信息生成并同时发送的上行帧。
所述至少两个站点发送的上行帧具有相同的时间长度。优选的，至少两个站点发送的上行帧可以是管理帧或控制帧。因为管理帧和控制帧的帧长度一般是固定的，这样，至少两个站点发送的上行帧的帧长度都是相同的，再根据共用的控制信息使得至少两个站点发送上行帧的传输速率也相同，就能够使至少两个站点发送的上行帧时间长度相同，在时间上能够对齐。当上行帧是数据帧时，如果数据帧的帧长度相同，也可以通过本发明提供的无线局域网中的信息传输方法使得至少两个站点发送的数据帧在时间上对齐。
相比于现有技术填充非数据信息的方式，本发明提供的无线局域网中的信息传输方法在使得至少两个站点发送上行帧在时间长度上对齐的同时，没有发送非数据信息造成资源浪费，节省了资源。
本发明实施例提供的无线局域网中的信息传输方法，接入点向至少两个站点发送控制信息，接入点接收至少两个站点基于共用的控制信息生成并同时发送的上行帧，因为至少两个站点根据共用的控制信 息，可以按照相同的传输速率发送上行帧，而上行帧的帧长度又相同，也就是至少两个站点发送的上行帧时间长度相同，能够使得至少两个站点的上行帧在时间上对齐，而且没有发送非数据信息造成资源浪费，解决了现有技术中通过填充非数据信息实现不同站点接收时间对齐时，造成资源浪费的问题。
结合上述图3对应的实施例，本发明实施例提供另一种无线局域网中的信息传输方法，对应上述图3对应的实施例中所描述的无线局域网中的信息传输方法的接收侧，参照图3所示，包括以下步骤：
501、站点接收接入点发送的控制信息。
控制信息是至少两个站点共用的，该站点属于至少两个站点。
至少两个站点可以根据控制信息确定出传输速率。至少两个站点根据确定出的相同的传输速率向接入点发送上行帧。优选的，接入点可以是WLAN网络中的AP，至少两个站点可以是至少两个STA，当然，此处只是举例说明，并不代表本发明局限于此。
可选的，控制信息还包括帧模式信息，帧模式信息用于指示至少两个站点发送上行帧时采用的帧模式。此处，需要说明的是，上行帧中一部分控制帧是具有固定长度的，例如ACK帧、CTS帧等。也有一部分帧具有不同的模式，不同的模式对应不同的长度。在步骤301有详细的说明，此处不再赘述。
可选的，设备的传输速率可以通过设备的MCS、带宽、公共NSTS、公共STBC等参数确定。控制信息可以包含至少两个站点的公共MCS、公共带宽、公共NSTS、公共STBC中的至少一项。需要说明的是，至少两个站点的公共MCS、公共带宽、公共NSTS、公共STBC都可以包含在控制信息中发送至站点，也可以是预先设定的，当某个参数预先设定时，该参数不需要通过控制信息发送。例如，可以预先设定至少两个站点都采用最低的MCS调制，此时，控制信息中也不需要包含至少两个站点的MCS，当然，此处只是举例说明，并不代表本发明局限于此。
作为一个特例，当所有的参数都通过预先设定的方式发送时，所 有的参数都不需要通过控制信息进行发送。此时，接入点发送控制信息以使得多个站点的上行帧能够同步地进行发送，该控制信息中还可以包含对多个站点的资源分配。
可选的，控制信息还可以包括元素字段指示，元素字段指示用于指示至少两个站点发送的上行帧包含的元素字段。
在一种应用场景中，当控制信息包含站点的子信道数目M或信道数目K时，站点根据控制信息在M个子信道或K个信道上发送上行帧，站点的子信道数目或信道数目为站点发送上行帧时所占用的子信道数目或信道数目，M、K为大于0的整数。需要说明的是，通常情况下，一个信道占用20MHz(兆赫兹)的带宽，子信道是组成信道的单元，一个信道包含多个子信道。
当控制信息包括子信道数目M的时候，接入点可以确定具体M个子信道的位置以避免不同的M个子信道有重叠的时候发生冲突。具体地，子信道数目M用于指示将所有可用的子信道中按照1～M个子信道，第M+1～2M个子信道，第2M+1～3M子信道，...进行分组，每一组包含M个子信道供站点发送上行帧使用。对于多个信道的情况，也可以采用这样的方式来确定信道的位置。当然，还可以采用其它的方式来确定多个子信道或者多个信道的位置。
或者，可选的，站点在接收接入点发送的下行数据时所占用的至少一个子信道中的每个子信道上发送上行帧，或者，站点在接收接入点发送的下行数据时所占用的至少一个信道中的每个信道上发送上行帧，即在接收下行数据的每个子信道上发送一次上行帧，或在接收数据的每个信道上发送一次下行帧，优选的，当控制信息不包含站点的子信道数目M或信道数目K时，可以这样发送。
可选的，控制信息包含于下行帧的公共控制字段，公共控制字段位于下行帧PL层的HE-SIG，或者公共控制字段位于下行帧的MAC层。
502、站点根据控制信息向所接入点发送上行帧。
至少两个站点的上行帧同时发送且具有相同的时间长度。
至少两个站点以接入点发送的下行帧作为同步帧，在下行帧之后间隔固定的帧间间隔，例如短帧间间隔(Short Interframe Space，SIFS)，同时向接入点发送上行帧。在本专利中每个站点所发送的相同类型的上行帧，当同一类型的上行帧具有多种模式或元素字段选择而导致不同长度时，将通过控制信息中的帧模式或元素字段指示使得至少两个站点中的每个站点选择的上行帧具有相同的长度。又由于控制信息中携带控制发送速率的公共参数，如公共MCS、公共带宽、公共NSTS、公共STBC等，因此每个站点传输上行帧所用的时间长度时相同的。因此至少两个站点的上行帧是同时发送且具有相同的传输时间长度，达到了对齐的效果。
本发明实施例提供的无线局域网中的信息传输方法，站点接收接入点发送的控制信息，站点根据控制信息向接入点发送上行帧，因为至少两个站点根据控制信息，可以按照相同的传输速率发送上行帧(一般的，指上行管理帧或者上行管理帧)，而上行帧的帧长度又相同，也就是至少两个站点发送的上行帧时间长度相同，能够使得至少两个站点的上行帧在时间上对齐，而且没有发送非数据信息造成资源浪费，解决了现有技术中通过填充非数据信息实现不同站点接收时间对齐时，造成资源浪费的问题。
基于上述图3对应的实施例，本发明实施例提供一种无线局域网中的通信装置，应用于无线局域网(WLAN)中，用于执行上述图3对应的实施例中所描述的无线局域网中的信息传输方法，优选的，该通信装置可以是图2所示的WLAN网络中的接入点201，参照图6所示，该通信装置60包括发送单元601和接收单元602。
