Utilization rate.
  • Traditional WLAN technology does not have OFDMA technology, and uplink and downlink OFDMA will be introduced in HEW.

Description

资源配置信息的指示方法及装置 技术领域
本文涉及但不限于通信领域,尤其涉及一种资源配置信息的指示方法及装置。
背景技术
目前,随着更多的人使用WLAN(Wireless Local Access Network,无线局域网)进行数据通信,WLAN网络负载也在不断加重,IEEE(Institute of Electrical and Electronics Engineers,电气和电子工程师协会)工业规范802.11组,先后定义了IEEE 802.11a/b/g/n/ac等一系列标准来满足不断增长的通信需求,这些标准多是致力于改进802.11的技术以提高最大物理层传输速率或网络最大吞吐量。但是,随着用户数目的增多,WLAN网络的效率会出现明显下降的趋势,单纯提高速率并不能解决该问题,因此,工作组成立相关的HEW(High Efficiency WLAN,高效无线局域网)小组致力于解决WLAN网络效率问题,尤其是密集部署场景和室外场景的网络效率。HEW小组是IEEE802.11ax小组,因此HEW的标准也被称为802.11ax标准。
WLAN在演进过程中,带宽从最初802.11a/g的20MHz,到802.11n最大40MHz,到802.11ac的最大必选带宽80MHz,最大可选带宽是160MHz。目前HEW的带宽基本上认为与802.11ac一样。在带宽不变的条件下,HEW小组的目标是提升至少4倍于传统网络的吞吐量,OFDMA(Orthogonal Frequency Division Multiple Access,正交频分多址接入)和MU-MIMO(Multi-User Multiple Input Multiple Output,多用户多输入多输出)技术是性能提升的关键保证。
OFDMA技术的引入使得多个用户在整个带宽上频分复用,能更优地利用用户间频率选择的结果提高频率利用率,并能降低小包传输的竞争资源开销占整个传输的比例,提高时间利用率。传统的WLAN技术没有OFDMA技术,HEW中将引入上下行OFDMA。
MU-MIMO将MIMO的多层分给多个用户,直接利用空间复用技术提高了时间和频率的利用率。802.11ac下行已经引入了MU-MIMO,HEW中将引入上行MU-MIMO。
OFDMA技术将同一段时间的频率资源分配给多个用户,需要用调度信息指示每个用户的资源。以5MHz的资源分配粒度为例,160MHz上最多将支持32个用户。HEW小组确定的最小带宽粒度大约是2MHz。用户数量多,资源分配支持多种粒度都会引起调度信息开销增大。
在相关技术中,图1是相关技术中的帧结构示意图,如图1所示,包括传统帧头的3部分L-STF、L-LTF、L-SIG,接着是HEW的SIG部分,包括HE-SIG-A和HE-SIG-B,接着是HE-STF和HE-LTF,最后是HEW的数据部分。其中HE-LTF已经确定多用户多子信道之间是对齐的,即开始和结束的时间点相同。而HE-STF也是对齐的,表明HE-SIG-B也需要时域对齐。
HEW的SIG部分携带控制信息,其中HE-SIG-A的内容是公共类信息,需要HEW的设备能读懂。包括带宽,BSS(Base Station Subsystem,基站子系统)的color信息,解析HE-SIG-B需要的信息等;HE-SIG-B的内容主要是资源配置信息,其中包括资源分配信息和解数据包需要的信息等,主要是发送给本次调度的用户。HE-SIG-A与传统WLAN的L-SIG类似,以20MHz为单位在本次调度可用的频带上重复发送。HE-SIG-B分为两部分,公共部分和专用部分。公共部分包括所有用户或者多个用户共用的配置信息,而专用部分是单个用户或者用户组的配置信息,其中包括数据资源分配信息。本文涉及HE-SIG-B的专用部分占用的资源与其所指示的调度资源之间的关系。
AP(Access Point,无线访问节点)根据调度结果指示资源配置信息。基础方案是将资源配置信息放置在与所分配的资源对应的位置,便于用户解析。图2是相关技术中HE-SIG-B和数据域的帧结构示意图,如图2所示,payload(数据域)不同底纹代表分给不同用户的资源,HE-SIG-B专用部分不同的底纹代表后面同底纹资源的指示信息。
在相关技术中,帧结构要求资源配置信息域的每个20MHz信道可以放不同的内容,但是时间结束点必须一致。在此条件下,相关技术中的方案存在两个问题:问题1:当每个带宽上用户数量差异较大时,每个带宽上的资源 配置信息总长度差异较大,需要对短的信息做补齐,效率很低;问题2:当为用户分配的资源大于20MHz时,严格对齐的方式有两种方式:方式一、资源配置信息放在其中一个20MHz上发送,那么其余20MHz将被浪费;方式二、资源配置信息在每个20MHz上重复,本身也不是必要。两种方式也会导致效率低的问题。
针对相关技术中,全局频域指示时,资源配置信息开销大的问题,目前还没有有效的解决方案。

本可选实施例提供了在不限制终端的资源配置信息所在频域资源与为终端的数据分配的频域对应时,一种资源配置信息的指示方法,包括:

所述带宽跨度信息的长度可能为固定值,也可以为与支持的带宽或者与资源配置信息限定的带宽范围有关的确定值。
当所述关系指示信息中的所述分配的所述数据的频域位置的跨度相对大小指示信息指示所述资源配置信息的频域位置宽度大于或等于所述资源配置信息中分配的所述数据的频域位置时,所述关系指示信息中包括所述分配的所述数据的频域位置与所述资源配置信息的频域位置是否有交集的指示信息。

当所述分配的所述数据的频域位置与所述资源配置信息的频域位置是否有交集的指示信息指示没有交集时,所述关系指示信息中包括所述带宽偏移信息。根据第二预定规则确定所述资源配置信息中资源指示的开销。

上述的关系指示信息可以对应多个终端,即所述多个终端中所有的既定图样的资源都采用统一的关系指示信息配置。
接收端:
接收端在接收到所述无线帧后,依据所述无线帧中的关系指示信息对所述无线帧中的资源配置信息中指示的内容进行解析,其中,所述关系指示信息中指示的内容包括以下至少之一:所述资源配置信息的频域位置宽度是否大于或等于资源配置信息中分配的数据的频域位置的跨度,所述资源配置信息的频域位置与资源配置信息中分配的所述数据的频域位置是否有交集,带宽偏移信息,带宽跨度信息;根据关系指示信息获取资源指示的开销并解析整个资源配置信息,获得所分配资源的位置。
或者,接收端在接收到所述无线帧后,对其中的关系指示信息中的带宽跨度信息进行解析,获取资源指示的开销并解析整个资源配置信息,获得所分配资源的位置。
通过上述可选实施例,根据资源配置信息调整后的位置与所指示的资源位置的关系,以尽量小的指示开销达到资源配置信息灵活调度,提高资源配置信息的资源利用率的效果。
在相关技术中的帧结构如图1所示,包括传统帧头部分(同IEEE 802.11n及IEEE 802.11ac的帧结构中的L-STF、L-LTF、L-SIG),HE-SIG-A,HE-SIG-B,HE-STF,HE-LTF以及数据区域。其中HE-LTF根据空时流数或者天线数是可变长度的,例如每空时流对应1个时域的OFDM符号长,如果支持最大空时流数为N,则最大HE-LTF域的个数为N个OFDM符号长。HE-SIG-A承载公共调度指示信息,HE-SIG-B承载用户相关的用户特有的调度信息。 HE-SIG-A中指示解码HE-SIG-B必要的信息。
在相关技术中,基于OFDM技术的WLAN标准都是固定的子载波间隔,即每20MHz分为64个子载波,子载波间隔为312.5kHz。802.11ax将子载波间隔缩小为原来的1/4,在相同的带宽上子载波数量为原来的4倍。因此,将原来的子载波系统称为1X,而将4倍的新子载波系统称为4X。802.11ax的数据仅支持4X,因此20MHz内有256个子载波。在帧结构中将HE-SIG-A和HE-SIG-B放在1X区域,而将数据放在4X区域,HE-STF和HE-LTF是可变的。
图7是根据本发明可选实施例的HE-SIG-B和数据域的帧结构示意图,如图7所示,为了解决资源配置信息区域的资源利用率低的问题,本可选实施例不限制终端的资源配置信息所在频域资源与为终端的数据分配的频域对应。即允许终端的资源分配信息的频域位置与为终端的数据分配的频域资源不相同。
发送端发送包含多个终端的数据的无线帧,该无线帧至少包含上述多个终端的的资源配置信息和发送给所述多个终端的数据。其中资源配置信息包含为终端分配的资源的位置信息和所分配资源上的数据的编解码信息,所述无线帧还包含资源配置信息的频域位置与资源配置信息中分配的数据的频域位置的关系指示信息,该关系指示信息用于确定资源配置信息中资源指示(即分配的所述数据的频域位置的指示信息)的开销及所指示资源(即所述数据)的频域位置。
下面在8个实施例中分别描述该发明实施例的使用方法。
实施例1
图8是根据本发明可选实施例的实施例1的帧结构示意图,如图8所示,终端的资源配置信息标识为HE-SIG-B,占用20MHz带宽,其中指示的资源表示为payload中与其同底纹的资源。图8表示了3种情况,分配的资源为一块小于20MHz的资源、等于20MHz的资源、多于一块的总量小于20MHz的资源。这3种情况,判断条件1:终端的资源配置信息的频域位置宽度是否大于或等于资源配置信息中分配的数据的频域位置的跨度,结果都为是。因此需要继续判断条件2。
在该图8中,条件2是判断终端的资源配置信息的频域位置与资源配置信息中分配的数据的频域位置是否有交集,其结果是有交集。因此根据预定规则(相当于上述实施例中的第一预定规则)确定资源配置信息中资源指示的开销。
图9是根据本发明可选实施例的实施例1的资源块编号示意图,如图9所示,给出了802.11ax的20MHz内的资源块编号示例,20MHz一共有256个子载波(称为tone),除去两侧的保护边带和中心的直流子载波以外,剩余的资源组织如下:0到8号是26tone的资源粒度,9到12是52tone的资源粒度,13、14是106tone的资源粒度,15是20M的238tone的资源粒度。这样一共需要4比特指示20MHz内的RU(Resource Unit,资源单元)。因此该例中N1=4。
3种情况的payload,第一种是RU 13,第二种是RU 15,第三种是两个RU:RU 9和RU 13。
发送端在HE-SIG-B中指示以上两个条件值,并用确定的长度指示相应的payload,接收端解到HE-SIG-B信息时,判断其中指示的资源位置位于与HE-SIG-B所在位置为相同的20MHz上,带内的每个RU编号用固定长度例如4比特解析。
实施例2
图10是根据本发明可选实施例的实施例2的帧结构示意图,如图10所示,在实施例2的示意图中,终端的资源配置信息标识为HE-SIG-B,占用20MHz带宽,其中指示的资源表示为payload中与其同底纹的资源。图10表示了3种情况,分配的资源为一块小于20MHz的资源、等于20MHz的资源、多于一块的总量小于20MHz的资源。这3种情况,判断条件1:终端的资源配置信息的频域位置宽度是否大于或等于资源配置信息中分配的数据的频域位置的跨度,结果都为是。因此需要继续判断条件2。
在该图10中,条件2是判断:终端的资源配置信息的频域位置与资源配置信息中分配的数据的频域位置是否有交集,其结果是无交集。因此需要指示带宽偏移信息:资源配置信息的频域位置与其中分配的数据的频域位置的偏移。该偏移值是基本信道带宽,例如20MHz的倍数,需遵守传统协议例如 802.11ac中的带宽使用规则(信道化规则)。该偏移值可能是在支持的带宽内循环移位的数值。该带宽偏移信息的长度可能为固定值,也可能为与支持的带宽或者与资源配置信息限定的带宽范围有关的确定值。
循环移位的计算方式可以设定为从HE-SIG-B当前所在带宽开始朝频率增大方向计算有几个20MHz的移位。图11是根据本发明可选实施例的实施例2的循环移位计算示意图,如图11所示,两种带宽160MHz和80MHz上的循环移位计算方法。0代表HE-SIG-B的位置,其余位置中的数字代表带宽移位值。在实施例2中,假设HE-SIG-B所在的带宽是主20MHz,所指示的资源在辅20MHz上,并且辅20MHz的频率大于主20MHz的频率,因此带宽移位信息取值为1。
当该实例在80MHz范围内指示时,带宽移位信息用2比特指示;当该实例在160MHz范围内指示时,带宽移位信息用3比特指示;当该实例在40MHz范围内指示时,带宽移位信息用1比特指示(相当于上述实施例的第二预定规则)。
同实施例1,可以用固定的长度4比特指示20MHz内一个既定图样的资源的分配。3种情况的payload,第一种是RU 13,第二种是RU 15,第三种是两个RU:RU 9和RU 13.
发送端在HE-SIG-B中指示以上两个条件值和带宽偏移信息,并用确定的长度指示相应的payload,接收端解到HE-SIG-B信息时,判断其中指示的资源位置位于与HE-SIG-B所在位置相邻的20MHz上,带内的每个RU编号用固定长度例如4比特解析。
实施例3
图12是根据本发明可选实施例的实施例3的帧结构示意图一;图13是根据本发明可选实施例的实施例3的帧结构示意图二;如图12和图13所示,终端的资源配置信息标识为HE-SIG-B,占用20MHz带宽,其中指示的资源表示为payload中与其同底纹的资源。在图12中,示意了两种资源分配情况:多于一块的跨度为40MHz的情况、一块连续的40MHz的资源。在图13中,payload的跨度也是同样的两种情况,跨度是40MHz。图12和图13图的区别是图12中HE-SIG-B所占资源与其所指资源有交集,而图13没有交集。
判断条件1:终端的资源配置信息的频域位置宽度是否大或于等于资源配置信息中分配的数据的频域位置的跨度。该实施例中图12和图13的条件1都是否。因此需要继续确定带宽跨度信息:终端的资源配置信息的频域位置与其中分配的数据的频域位置的合集的带宽跨度。该跨度的确定需遵守传统协议中的带宽使用规则。即802.11中规定的带宽原则,物理相邻的两个20MHz,带宽跨度不一定是40MHz,也可能是80MHz的主辅40MHz上的两部分,就属于80MHz。假设图12的HE-SIG-B所在位置是主20MHz,所指示的资源跨度为主40MHz,因此图12的带宽跨度信息为40MHz。假设图13的payload资源跨度为主40MHz,HE-SIG-B所在的资源是辅40MHz资源位置的一部分,则图13的带宽跨度信息为80MHz。另外一种假设图13的payload的资源跨度为辅40MHz,而HE-SIG-B所在的资源是辅80MHz资源位置的一部分,则图13的带宽跨度信息为160MHz。
上述带宽跨度信息的长度可能为固定值,即固定为2比特,支持20/40/80/160MHz,或者根据SIGA中的带宽信息确定该范围,小于80MHz为1比特,大于等于80M为2比特(相当于上述实施例第三预定规则)。
发送端在HE-SIG-B中指示条件1为否的情况下的带宽跨度信息,根据带宽跨度信息确定RU的指示开销,图14是根据本发明可选实施例的实施例3的带宽跨度信息的示意图,如图14所示,20MHz有16种RU待指示,用4比特,40MHz有至少33种RU待指示,用6比特,80MHz至少有68种需要7比特,160MHz需要8比特。另外,20MHz以上的带宽也可以用较少的比特指示非完全的图示的集合。例如,图14中40MHz本身有33种RU指示,可以减少一种20MHz的RU指示,同时限定等于20MHz的RU的数据资源的资源分配信息只对应其所在的20MHz。那么40MHz的RU指示开销就是5比特。类似地,80MHz可以用6比特,160MHz可以用7比特。
确定开销后,用确定的长度指示相应的payload,接收端解到HE-SIG-B信息时,根据带宽跨度信息判断RU编号的长度,解析其中指示的资源位置。
实施例4
图15是根据本发明可选实施例的实施例4的带宽跨度信息的示意图,如图15所示,如图15所示,本实施例提供一种20MHz用5比特固定长度指示 的方案。其中,16种情况指示20MHz内部的每个RU,用4比特足够,再扩展1比特,用其中的3个指示连续40MHz、连续80MHz,连续160MHz的情况。
在这种假定下,如果分配的数据部分资源是40MHz、80MHz、160MHz的连续资源,则条件1的判断都按照数据部分的跨度为20MHz来特殊处理,每个RU的指示开销是5比特。并且每个20MHZ以内的RU指示开销也是5比特(相当于上述实施例第四预定规则)。
实施例5
实施例3的图12和图13中,终端的资源配置信息标识为HE-SIG-B,占用20MHz带宽,其中指示的资源表示为payload中与其同底纹的资源。在图12中,示意了两种资源分配情况:多于一块的跨度为40MHz的情况、一块连续的40MHz的资源。在图13中payload的跨度也是同样的两种情况,跨度是40MHz。图12和图13的区别是图12的HE-SIG-B所占资源与其所指资源有交集,而图13没有交集。
发送端直接给出关系指示信息指示带宽跨度信息。该带宽跨度信息是指终端的资源配置信息的频域位置与其中分配的数据的频域位置的合集的带宽跨度。该跨度值的确定需遵守传统协议中的带宽使用规则。即802.11中规定的带宽原则,物理相邻的两个20MHz,带宽跨度不一定是40MHz,也可能是80MHz的主辅40MHz上的两部分,就属于80MHz。假设图12的HE-SIG-B所在位置是主20MHz,所指示的资源跨度为主40MHz,因此图12的带宽跨度信息为40MHz。假设图13的payload资源跨度为主40MHz,HE-SIG-B所在的资源是辅40MHz资源位置的一部分,则图13的带宽跨度信息为80MHz。另外一种假设图13的payload的资源跨度为辅40MHz,而HE-SIG-B所在的资源是辅80MHz资源位置的一部分,则图13的带宽跨度信息为160MHz。
上述带宽跨度信息的长度可能为固定值,即固定为2比特,支持20/40/80/160MHz,或者根据SIGA中的带宽信息确定该范围,小于80MHz为1比特,大于等于80M为2比特(相当于上述实施例第四预定规则)。
发送端在HE-SIG-B中指示带宽跨度信息,根据带宽跨度信息确定RU的指示开销,如实施例3的图14所示,20MHz有16种RU待指示,用4比特, 40MHz有至少33种RU待指示,用6比特,80MHz至少有68种需要7比特,160MHz需要8比特。确定开销后,用确定的长度指示相应的payload,接收端解到HE-SIG-B信息时,根据带宽跨度信息判断RU编号的长度,解析其中指示的资源位置。
实施例6
图16是根据本发明可选实施例的实施例6的带宽跨度信息的示意图,如图16所示,实施例6是系统调度了6个终端,每个终端有一块RU资源,HE-SIG-B针对每个终端组织资源配置信息,每个终端带一个RU。对每个终端的资源配置信息指示HE-SIG-B所占用资源与对应的资源合集的带宽跨度,终端3的HE-SIG-B指示跨度为80MHz,因此终端3的每个RU占用7比特开销,RU在80MHz内指示资源。而其他终端的跨度都是20MHz,每个RU占用4比特开销。
实施例7
图17是根据本发明可选实施例的实施例7的带宽跨度信息的示意图,如图17所示,实施例7是系统调度了6个终端,其中终端5有两块RU资源,HE-SIG-B针对每个终端组织资源配置信息,每个终端的所有RU都用统一的资源配置信息。对每个终端的资源配置信息指示HE-SIG-B所占用资源与对应的资源合集的带宽跨度,终端3的HE-SIG-B指示跨度为80MHz,因此终端3的每个RU占用7比特开销,RU在80MHz内指示资源。终端5有两块资源,其HE-SIG-B与所分配资源的带宽跨度为40MHz,每个RU用6比特开销指示。而其他终端的跨度都是20MHz,每个RU占用4比特开销(相当于上述实施例第四预定规则)。
实施例8
为更多地节约指示开销,一个20MHz内的HE-SIG-B只配置统一的资源配置信息,在实施例7的图17中,辅20MHz带宽上有两个终端的资源配置信息,终端4的跨度是20MHz,终端3的跨度是80MHz,统一配置时按照较大开销的配置。一般地说,当一个20MHz带宽上有能力接纳其他带宽移入的HE-SIG-B时,其资源利用压力较小,每个带宽配置同样的开销,虽然会另接纳其他带宽移入的原来带宽上的HE-SIG-B开销变大,但是由于总体上资源 配置指示信息的开销减小,有利于压力较大的带宽上的指示资源节约。总体上,也是有好处的。
通过以上的实施例的描述,本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更普遍的实施方式。基于这样的理解,本发明实施例的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括一条或多条指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本发明实施例所述的方法。

可选地,在本实施例中,处理器根据存储介质中已存储的程序代码执行上述实施例的方法。
显然,本领域的技术人员应该明白,上述的本发明实施例的模块或步骤可以用通用的计算装置来实现,它们可以集中在单个的计算装置上,或者分布在多个计算装置所组成的网络上,可选地,它们可以用计算装置可执行的程序代码来实现,从而可以将它们存储在存储装置中由计算装置来执行,并且在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤,或者将它们分别制作成集成电路模块,或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。本发明实施例不限制于任何特定的硬件和软件结合。
