这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明实施例相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开实施例涉及的执行主体包括但不限于:无线通信网络尤其是Wi-Fi网络如IEEE802.11a/b/g/n/ac标准下,以及下一代Wi-Fi网络中IEEE802.11be标准下的网络设备,其中,网络设备包括但不限于:无线接入点(AP,Access Point)、无线站点(STA,Station)等。
本公开实施例的一种应用场景为,在IEEE802.11ax标准中规定,在一 定带宽下一次只能够分配一个RU给无线站点。为了提高频谱的利用效率,在IEEE802.11be中在一定的带宽下能够分配两个或两个以上RU给一个无线站点,具体可以分配给一个无线站点的数量没有确定。
如图1所示,本示例性实施例提供一种于通信资源单元分配方法,可以应用于无线通信的第一无线通信设备中,该方法包括:
步骤101:接收第二无线通信设备发送的消息,其中,消息包含指示第二无线通信设备具有的天线数量的信息元素。
这里,第一无线通信设备可以是Wi-Fi通信技术中的无线接入点(AP,Access Point),第二无线通信设备可以是Wi-Fi通信技术中的无线站点(STA,Station)。
在本公开实施例中,该消息可以为消息帧。在一些实施例中,该消息可以为管理帧和/或数据帧。当然,该消息还可以是任何恰当的方式,本公开实施例中并不对此做出限定。
在一些实施例中,消息可以是Wi-Fi通信技术中第一无线通信设备发送的管理帧。
示例性的,管理帧可以包括:探测请求(probe request)帧、关联请求(association request)帧或授权请求帧(authentication request)帧等。信息元素(Information Element)是消息中用于设置指示信息的基本信息单元。
在一些实施例中,该消息还可以是数据帧。
第二无线通信设在与第一无线通信设备在关联(association)过程或重新关联(re-association)过程中,会互相向对方发送管理帧。第二无线通信设备可以在关联过程或重关联过程中,向第一无线通信设备发送包含第二无线通信设备具有的天线数量的信息元素的消息。如此,第一无线通信设备可以通过该消息确定第二无线通信设备具有的天线数量。其中,包含第二无线通信设备具有的天线数量的信息元素可以是新应用的信息元素。其 中,无线站点与无线接入点进行关联,以便获得网络的完全访问权。关联属于一种记录保持过程,它让AP能够记录无线站点,以便将传送给无线站点的消息送给正确的无线站点。重关联过程是指无线站点与无线接入点脱离关联关系后,再次进行关联的过程。
第二无线通信设备可以设置有两个或两个以上天线,不同天线可以具有不同的指向,不同指向的天线在发送信号时可以将能量集中在想要传输的方向,增加信号传输性能,在接收信号时,可以接收不同方向的信号,加强接收效果。
第一无线通信设备可以根据第二无线通信设备支持的天线数量,确定第二无线通信设备的数据传输能力,作为后续进行波束赋形等操作的依据。
如此,第二无线通信设备通过消息中的信息元素指示第二无线通信设备具有的天线数量,提供了一种天线数量显性指示方式,第一无线通信设备可以根据信息元素指示信息确定第二无线通信设备具有的天线数量;第二无线通信设备具有的天线数量可以标注第二无线通信的波束成形等通信能力,进而可以提高第一无线通信设备对于第二无线通信设备通信能力的识别效率。
在一些实施例中,该方法还包括:根据第二无线通信设备具有的天线数量,确定分配给第二无线通信设备的资源单元(RU,Resource Unit)的数量。
这里,RU可以是由两个或两个以上子载波组成的传输资源。IEEE802.11ax标准中,支持的RU格式包括:26-子载波(tone)、52-tone、106-tone、242-tone、484-tone、996-tone或2*996-tone。
第一无线通信设备和第二通信设备在利用RU进行数据交互时,可以对每个RU的载波进行波束赋形。波束赋形和天线数量相关,一般一个连续带宽的载波进行波束赋形时可只占用一根天线。因此,天线数量可以决定连 续带宽的载波的数量,进而决定RU的数量。
示例性的,第一无线通信设备可以分配给第二通信设备与天线数量相同的RU。如此,每个RU的载波都可以占用一根天线进行波束赋形。
如此,将第二无线通信设备的天线数量作为RU分配的依据,使RU的分配与第二无线通信设备的天线数量相匹配,不会出现不连续载波的个数多于天线数量的情况,提高RU分配的准确性,提高数据传输可靠性。
在一些实施例中,其中,根据第二无线通信设备具有的天线数量,确定分配给第二无线通信设备的RU的数量,包括:
如果为第二无线通信设备分配的两个或两个以上RU在频域上不连续,则分配给第二无线通信设备的RU的数量,小于或等于第二无线通信设备具有的天线数量。
在工作带宽下,第一无线通信设备可以给一个第二无线通信设备分配两个或两个以上RU,两个或两个以上RU可以在频域上连续,也可以在频域上不连续。
如果分配的每个RU在频域上全部不连续或是部分不连续,则需要针对不连续的每个RU的载波分别做波束赋形,而连续的RU可以一起做波束赋形,也可以分别做波束赋形。由于一个带宽的载波在波束赋形时需要占用一个天线,即每个RU需要占用一个天线,因此,第一无线通信设备对第二无线通信设备所分配的最大RU的数量为第二无线通信设备所具有的天线数量,即第一无线通信设备可以分配的RU的数量小于或等于第二无线通信设备所具有的天线数量。
如此,一方面,使RU的分配更符合实际传输条件,提高RU分配的准确性,提高数据传输可靠性;另一方面,当第二无线通信设备的天线数量为两个或两个以上时,可以分配两个或两个以上RU,提高频谱利用率,进而提高传输吞吐量。
在一些实施例中,其中,根据第二无线通信设备具有的天线数量,确定分配给第二无线通信设备的RU的数量,包括:
根据第二无线通信设备具有的天线数量,确定在带宽中分配给第二无线通信设备的RU的数量。
第二无线通信设备可以支持在不同的工作带宽进行工作,例如:20MHz、40MHz、80MHz、160MHz、160MHz+80MHz、160MHz+160MHz或320MHz等。分配给第二无线通信设备的RU的数量可以是在一个工作带宽下的RU的数量。例如,第一无线通信设备可以根据在第二无线通信设备具有的天线数量,确定第二无线通信设备20MHz工作带宽下的RU的数量。
在一些实施例中,其中,该方法还包括以下至少之一:
如果为第二无线通信设备分配的两个或两个以上RU在频域上不连续,则分别对不连续的每个RU的载波进行波束赋形;
如果为第二无线通信设备分配的两个或两个以上RU在频域上连续,并且两个或两个以上RU包括的子载波数之和等于第一子载波数,则将两个或两个以上RU的载波合并进行波束赋形;
如果为第二无线通信设备分配的两个或两个以上RU在频域上连续,并且两个或两个以上RU包括的子载波数之和大于或小于第一子载波数,则对两个或两个以上RU的每个RU的载波分别进行波束赋形。
这里第一子载波数可以是IEEE802.11ax标准支持RU格式中包括的26、52、106、242、484、996和2*996七种子载波数中的任一种。即在IEEE802.11ax标准中,可以被传输的RU中的子载波数可只为上述七种中的任一种。
在一些实施例中,将两个或两个以上RU的载波合并进行波束赋形,可以是将两个或两个以上RU的载波合并成一个载波,然后对这一个载波进行波束赋形。
在工作带宽下,第一无线通信设备可以给一个第二无线通信设备分配两个或两个以上RU,这些RU可以在频域上连续,也可以在频域上不连续,还可以是部分RU在频域上连续而部分RU在频域上不连续。
如果分配的每个RU在频域上不连续或是部分RU在频域上不连续,则针对不连续的RU的载波需要分别做波束赋形。由于一个带宽的载波在波束赋形时需要占用一个天线,即不连续的RU中的每个RU各需要占用一个天线,因此,第一无线通信设备或第二无线通信设备需要针对每个RU的载波分别进行波束赋形。
示例性的,第一无线通信设备为第二无线通信设备分配了两个频域上不连续的两个RU,一个RU包括26个子载波,另一个包括52个子载波,第一无线通信设备或第二无线通信设备可以分别为两个RU分别进行波束赋形。
如果第一无线通信设备分配给第二无线通信设备的两个或两个以上RU在频域上连续,并且两个或两个以上RU的子载波数量之和为IEEE802.11ax标准支持的七种RU格式包含子载波数量中的任一种,则可以将两个或两个以上RU的载波一起进行波束赋形,采用一根天线进行发送。
示例性的,第一无线通信设备分配给第二无线通信设备的两个RU在频域上连续,两个RU包含的子载波数分别为26和26。两个RU包含的子载波数之和为52,属于IEEE802.11ax标准支持的七种RU格式包含子载波数量中的一种,则可以将这些RU的载波一起进行波束赋形,采用一根天线进行发送。
如果第一无线通信设备分配给第二无线通信设备的两个或两个以上RU在频域上连续,并且两个或两个以上RU的子载波数量之和不为IEEE802.11ax标准支持的七种RU格式包含子载波数量中的任一种,第一 无线通信设备或第二无线通信设备可以分别对每个RU的载波进行波束赋形。
示例性的,第一无线通信设备为第二无线通信设备分配了频域上连续的两个RU,一个RU包括26个子载波,另一个RU包括52个子载波,两个RU总共包括的子载波数之和为78个子载波,不属于IEEE802.11ax标准支持的七种RU格式包含子载波数量中的任一种;此时,为了兼容IEEE802.11ax标准,第一无线通信设备或第二无线通信设备可以分别对两个RU的载波单独进行波束赋形。
当然,如果IEEE802.11ax标准中支持的RU格式发生了变化,则本公开所有实施例中的第一子载波数也可以随之调整,本公开实施例并不对此做出限定。当然,也可以基于其他方式确定第一子载波数的数量,本公开实施例也不对此做出限定。其中,当本公开实施例中的第一无线通讯设备和第二无线通讯设备不遵循IEEE802.11ax标准时,则可以无需设定第一子载波数这一参数,即本公开实施例中的方法包括:
如果分配的每个RU在频域上不连续或是部分RU在频域上不连续,则针对不连续的RU的载波需要分别做波束赋形。由于一个带宽的载波在波束赋形时需要占用一个天线,即不连续的RU中的每个RU各需要占用一个天线,因此,第一无线通信设备或第二无线通信设备需要针对每个RU的载波分别进行波束赋形。
如此,第一无线通信设备为第二无线通信设备采用的RU可以与IEEE802.11ax标准兼容,从而提高数据传输兼容性。
如果为第二无线通信设备分配的两个或两个以上两个或两个以上资源单元在频域上连续,则将两个或两个以上两个或两个以上资源单元的载波合并进行波束赋形。即,不考虑两个或两个以上RU的载波包含的子载波总数,两个或两个以上RU在频域上连续时就一起做波束赋形。
在一些实施例中,其中,信息元素包括以下至少之一:信息元素标识,用于标识信息元素;长度标识,用于指示信息元素的长度;天线数量标识,用于指示第二无线通信设备具有的天线数量。
如图2所示,示例性的,信息元素可以占用3个字节。其中,信息元素标识可以占用1个字节,信息元素标识用于标识信息元素。长度标识可以占用1个字节。天线数量标识占用1个字节,可以采用二进制数表示天线数量。
如图3所示,本示例性实施例提供一种于通信资源单元分配方法,可以应用于无线通信的第二无线通信设备中,该方法包括:
步骤201:发送消息,其中,消息包括用于指示第二无线通信设备具有的天线数量的信息元素。
这里,第一无线通信设备可以是Wi-Fi通信技术中的无线接入点(AP,Access Point),第二无线通信设备可以是Wi-Fi通信技术中的无线站点(STA,Station)。
在本公开实施例中,该消息可以为消息帧。在一些实施例中,该消息可以为管理帧和/或数据帧。当然,该消息还可以是任何恰当的方式,本公开实施例中并不对此做出限定。
在一些实施例中,消息可以是Wi-Fi通信技术中第一无线通信设备发送的管理帧。
示例性的,消息可以包括:探测请求(probe request)帧、关联请求(association request)帧或授权请求(authentication request)帧等。信息元素(Information Element)是消息中用于设置指示信息的基本信息单元。
示例性的,该消息还可以是数据帧。
第二无线通信设在与第一无线通信设备在关联(association)过程或重新关联(re-association)过程中,会互相向对方发送管理帧。第二无线通信 设备可以在关联过程或重关联过程中,向第一无线通信设备发送包含第二无线通信设备具有的天线数量的信息元素的消息。如此,第一无线通信设备可以通过消息确定第二无线通信设备具有的天线数量。其中,包含第二无线通信设备具有的天线数量的信息元素可以是新应用的信息元素。其中,无线站点与无线接入点进行关联,以便获得网络的完全访问权。关联属于一种记录保持过程,它让AP能够记录无线站点,以便将传送给无线站点的消息送给正确的无线站点。重关联过程是指无线站点与无线接入点脱离关联关系后,再次进行关联的过程。

在一些实施例中,分配给第二无线通信设备的RU数量是根据天线数量确定的。
这里,RU可以是由两个或两个以上子载波组成的传输资源。IEEE802.11ax中,支持的RU格式包括:26-子载波(tone)、52-tone、106-tone、242-tone、484-tone、996-tone或2*996-tone。

示例行的,第一无线通信设备可以分配给第二通信设备与天线数量相同的RU。如此,每个RU的载波都可以占用一根天线进行波束赋形。
如此,将第二无线通信设备的天线数量作为RU分配的依据,使RU的分配与第二无线通信设备的天线数量相匹配,不会出现不连续载波的个数多于天线数量的情况,,提高RU分配的准确性,提高数据传输可靠性。
在工作带宽下,第一无线通信设备可以给一个第二无线通信设备分配两个或两个以上RU,这些RU可以在频域上连续,也可以在频域上不连续,还可以是部分RU在频域上连续而其他RU在频域上不连续。
如果分配的两个或两个以上RU在频域上不连续,则需要针对不连续的每个RU的载波分别做波束赋形,而连续的RU可以一起做波束赋形,也可以分别做波束赋形。由于一个带宽的载波在波束赋形时需要占用一个天线,即每个RU需要占用一个天线,因此,第一无线通信设备对第二无线通信设备所分配的最大RU的数量为第二无线通信设备所具有的天线数量,即第一无线通信设备可以分配的RU的数量小于或等于第二无线通信设备所具有的天线数量。

如果为第二无线通信设备分配的两个或两个以上RU在频域上连续,并且两个或两个以上RU包括的子载波数之和大于或小于第一子载波数,则对两个或两个以上RU的每个RU的载波分别进行波束赋形。
这里第一子载波个数可以是IEEE802.11ax标准支持RU格式中包括的26、52、106、242、484、996和2*996七种子载波数中的任一种。即在IEEE802.11ax标准中,可以被传输的RU中的子载波数可只为上述七种中的任一种。
在一些实施例中,将两个或两个以上RU的载波合并进行波束赋形,可以是将两个或两个以上RU的载波合并成一个载波,然后对这一个载波进行波束赋形。
在工作带宽下,第一无线通信设备可以给一个第二无线通信设备分配两个或两个以上RU,这些RU可以在频域上连续,也可以在频域上不连续,还可以是部分RU在频域上连续而部分RU在频域上不连续。

示例性的,第一无线通信设备为第二无线通信设备分配了频域上连续 的两个RU,一个RU包括26个子载波,另一个RU包括52个子载波,两个RU总共包括的子载波数之和为78个子载波,不属于IEEE802.11ax标准支持的七种RU格式包含子载波数量中的任一种;此时,为了兼容IEEE802.11ax标准,第一无线通信设备或第二无线通信设备可以分别对两个RU的载波单独进行波束赋形。
当然,如果IEEE802.11ax标准中对于支持RU格式发生了变化,则本公开所有实施例中的第一子载波数也可以随之调整,本公开实施例并不对此做出限定。其中,当本公开实施例中的第一无线通讯设备和第二无线通讯设备不遵循IEEE802.11ax标准时,则可以无需设定第一子载波数这一参数,也就是本公开实施例中的方法包括:
如果分配的每个RU在频域上不连续或是部分RU在频域上不连续,则针对不连续的RU的载波需要分别做波束赋形。由于一个带宽的载波在波束赋形时需要占用一个天线,即不连续的RU中的每个RU各需要占用一个天线,因此,第一无线通信设备或第二无线通信设备需要针对每个RU的载波分别进行波束赋形。
如此,第一无线通信设备为第二无线通信设备采用的RU可以与IEEE802.11ax标准兼容,从而提高数据传输兼容性。
如果为第二无线通信设备分配的两个或两个以上两个或两个以上资源单元在频域上连续,则将两个或两个以上两个或两个以上资源单元的载波合并进行波束赋形。即,不考虑两个或两个以上RU的载波包含的子载波总数,两个或两个以上RU在频域上连续时就一起做波束赋形。
以下结合上述任意实施例提供一个具体示例:
1、RU分配最大数量的考虑
a、在一个的传输带宽下,无线接入点给一个无线站点分配一定数量的RU,在通信之前无线站点与无线接入点之间会进行波束赋形的操作,如果 每个RU的分配是不连续的,或者RU的分配连续,但RU子载波数之和与IEEE802.11ax规定不兼容,则所分配的RU可单独看作为一个信道通信。无线接入点在通信之前会对每个RU做波束赋形,由于波束赋形涉及到无线站点所支持天线的数量,所以无线接入点对无线站点所分配的最大RU的数量为无线站点所支持的最大天线数量;进行波束赋形时,可以首先发送零数据帧(NDP,Null data packet)作为波束赋形的探测帧。
b、兼容问题
在现有的IEEE802.11ax中,所支持的RU的格式包括:26-(子载波)tone、52-tone、106-tone、242-tone、484-tone、996-tone及2*996-tone七种,如无线站点在一个的带宽下所分配的连续RU为26-tone和52-tone,但考虑到兼容的问题,则在波束赋形时,只能作为两个信道,如连续分配了两个26-tone,则可作为一个信道做波束赋形。这里,无线站点可以工作在:20MHz、40MHz、80MHz、160MHz、160MHz+80MHz、160MHz+160MHz或320MHz的带宽下。当然,在不需要兼容IEEE802.11ax,则无需考虑IEEE802.11ax对于RU格式的限制,只需要根据分配的RU是否连续就可以确定如何进行波束赋形。
无线站点在与无线接入点的交互过程中将无线站点所支持天线最大数量的能力信息值发送给无线接入点,具体的可在探测请求帧、关联请求帧或授权请求帧中以信息元素的形式携带,信息元素具体格式可以如图2所示,其中元素标识(element ID)定义信息元素为新的信息元素,信息元素标识无线站点支持的最大天线数量。
