Description

资源分配方法、通信装置及相关设备 技术领域
本申请涉及通信技术领域,尤其涉及一种资源分配方法、通信装置及相关设备。
背景技术
传统的无线局域网(Wireless Local Area Network,WLAN)中,每个站点(station)需要发送上行数据时会通过竞争的方式占用整个信道进行数据传输,大降低了频率的利用效率。为了改善该情况,目前采用OFDMA技术在频域上将无线信道划分为多个子信道(子载波),形成一个个资源单元(resource unit,RU),用户数据承载在部分资源单元上,而不是占用整个信道,从而实现每个时间段内多个用户可同时并行传输,不必排队等待、相互竞争,提升了频率的利用效率。
在下行链路里,接入点(access point,AP)可根据各站点的下行数据的优先级来决定分配RU的情况,但在上行链路中,AP需要通过触发帧告知终端设备分配的资源单元。触发帧包括多个用户信息字段,一个用户信息字段包括一个站点需要读取的信息,如M个用户信息字段分别为站点1至站点M需要读取的信息。其中,在用户信息字段中资源单元分配子字段用于指示该站点被分配到的一个资源单元。进而,站点可在分配的资源单元上发送数据分组。
然而,每个站点需要上行传输的数据大小不同,如何为一站点分配多个资源单元是一个亟待解决的问题。
发明内容
本申请提供一种资源分配方法、通信装置及相关设备,能够为每个站点分配多个资源单元。
第一方面,本申请提供一种资源分配方法。该方法中,站点接收接入点发送的触发帧。该触发帧中包括与该站点的关联标识相同的多个用户信息字段,每个用户信息字段可用于指示为站点分配的一个或多个资源单元。因此,站点可确定该多个用户信息字段所分别指示的一个或多个资源单元,作为被分配的多个资源单元。
在另一种可能的设计中,该触发帧中包括与该站点的关联标识相同的一个用户信息字段,该用户信息字段可用于指示为站点分配的多个资源单元,从而也可实现为站点分配多个资源单元。该设计中采用一个用户信息字段为站点分配多个资源单元,能够降低所需的用户信息字段数量,从而有利于同时为多个站点分配多个资源单元。
在一种可能的实现方式中,站点根据所述触发帧确定被分配的多个资源单元,包括:所述站点从所述触发帧中,选择与所述站点的关联标识相同的一个或多个用户信息字段;针对选择的一个或多个用户信息字段中的每个用户信息字段,所述站点确定所述用户信息字段所指示的一个或多个资源单元;所述选择的一个或多个用户信息字段所分别指示的一个或多个资源单元为所述站点被分配的多个资源单元。
其中,触发帧中的用户信息字段可部署在用户信息列表字段中,因此,上述实现方式 也可为从用户信息列表字段中选择与所述站点的关联标识相同的一个或多个用户信息字段。
针对站点具体如何从用户信息列表字段中选择该一个或多个用户信息字段,以下阐述可选的四种可能的实现方式。该四种可能的实现方式也可相互结合使用,本申请不做限定。
一种可能的实现方式中,针对所述触发帧中的所有用户信息字段,所述站点分别解析每个用户信息字段中关联标识字段指示的关联标识;从解析的所有用户信息字段中,选择与所述站点的关联标识相同的一个或多个用户信息域。其中,所有用户信息字段可部署在用户信息列表字段中,站点可基于用户信息列表字段的边界,解析所有的用户信息字段。可见,该方式不需要修改用户信息列表字段,使得该资源分配方法的兼容性更好。
另一种可能的实现方式中,接入点可通过协议预定义的方式或信令的方式为站点配置N,该N为触发帧中包括与站点的关联标识相同的用户信息字段的个数。或者,接入点可通过协议预定义或信令的方式为站点配置能够分配的资源单元的个数N 1,每个用户信息字段能够指示的资源单元的个数N 2,这样,触发帧中包括与站点的关联标识相同的用户信息字段的个数N可等于N 1/N 2
该实现方式中,站点从所述触发帧中,选择与所述站点的关联标识相同的一个或多个用户信息字段,包括:所述站点根据所述触发帧中各用户信息字段的索引,解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同,直至与所述站点的关联标识相同的用户信息字段的个数等于N时,停止执行所述的解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同的步骤;从解析的各用户信息字段中,选择与所述站点的关联标识相同的N个用户信息字段。
可见,该实现方式能够降低站点解析用户信息字段的个数,从而有利于降低站点的处理负载。
又一种可能的实现方式,用户信息字段中可以包括结束标志。该结束标志可通过用户信息字段中在新增的比特位,或复用其他信息的字段,或利用预留字段的方式进行设置。该结束标志用于指示站点的资源单元分配是否结束。可见,该实现方式能够进一步的降低站点解析用户信息字段的个数,从而有利于降低站点的处理负载。
站点从所述触发帧中,选择与所述站点的关联标识相同的一个或多个用户信息字段,包括:所述站点根据所述触发帧中各用户信息字段的索引,解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同,直至所解析的用户信息字段中结束标志指示所述站点的资源单元分配结束时,停止执行所述的解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同的步骤;从解析的各用户信息字段中,选择与所述站点的关联标识相同的一个或多个用户信息字段。
又一种可能的实现方式中,站点从所述触发帧中,选择与所述站点的关联标识相同的一个或多个用户信息字段,包括:所述站点以所述触发帧中与所述站点的关联标识相同的第一个用户信息字段为起始,根据各用户信息字段的索引,解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同,直至解析到与所述站点的关联标识不同的用户信息字段为止;从解析的各用户信息字段中,选择与所述站点的关联标识相同的一个或多个用户信息字段。该实现方式中,各站点对应的多个用户信息字段可在 触发帧的用户信息列表字段中连续分布,能够大大降低站点的解析复杂度。
以下从一些可选的实现方式,阐述用户信息字段如何指示一个或多个资源单元,以及站点如何确定每个用户信息字段指示的一个或多个资源单元。
在一种可能的实现方式中,所述用户信息字段包括资源单元指示。所述站点确定所述用户信息字段所指示的多个资源单元,包括:所述站点确定所述用户信息字段中资源单元指示所指示的多个资源单元。可见,该实现方式中,资源单元指示可指示多个资源单元。

2个第一资源单元的组合,所述第一资源单元为包含996个子载波的资源单元;

320MHz内,频率最高的三个第一资源单元的组合;
2个第一资源单元的组合,所述第一资源单元为包含996个子载波的资源单元;
4个所述第一资源单元的组合。
在另一种可能的实现方式中,用户信息字段包括频带范围指示和资源单元指示。所述频带范围指示用于指示带宽中一个80MHz的频带范围;所述资源单元指示用于指示一个资源单元;所述站点确定所述用户信息字段所指示的一个资源单元,包括:所述站点根据所述频带范围指示所指示的频带范围,确定所述资源单元指示所指示的一个资源单元。可见,针对站点选择的多个用户信息字段,每个用户信息字段指示一个资源单元,从而能够获得站点被分配的多个资源单元。
可见,该实现方式中无论资源单元合并跨越的带宽大小有多大,需要多少个RU,均可采用同样数量的用户信息字段分别指示同样数量的RU即可。
可选的,所述资源单元指示所指示的一个资源单元为以下任意一个资源单元:
一第七资源单元,所述第七资源单元为包括2乘以996个子载波的资源单元;

具体实施方式
随着无线局域网的发展,站点进行上行数据传输需求的数据速率也随之增加,因此,接入点如何给站点分配多个资源单元,从而使得站点可利用多个资源单元进行上行数据传输,改善数据速率,成为一个亟待解决的问题。
为了解决该问题,本申请提供一种资源分配方法,该方法中,接入点能够为站点分配多个资源单元。其中,为该站点分配的多个资源单元也可以称为合并的多个资源单元或组合的多个资源单元。若不特别说明,本文中,“合并”、“组合”代表相同的含义。
首先,以图1为例阐述本申请所述的资源分配方法可适用的网络结构。图1是本申请实施例提供的一种网络结构的示意图,如图1所示,该网络结构可包括接入点(access point,AP)和多个非接入点类的站点(none access point station,non-AP STA)。为便于描述,后文将非接入点类的站点简称为站点。图1以该网络结构包括一个接入点(AP)和两个站点(STA 1、STA 2)为例进行说明。该网络结构中还可包括更多的接入点和站点。或者,该网络结构中也可以只包括两个站点,本申请不做限定。
其中,接入点可以为终端设备(如手机)进入有线(或无线)网络的接入点,主要部署于家庭、大楼内部以及园区内部,典型覆盖半径为几十米至上百米,当然,也可以部署于户外。接入点相当于一个连接有线网和无线网的桥梁,主要作用是将各个无线网络客户端连接到一起,然后将无线网络接入以太网。具体的,接入点可以是带有无线保真(wreless-fidelity,WiFi)芯片的终端设备(如手机)或者网络设备(如路由器)。接入点可以为支持802.11be制式的设备。接入点也可以为支持802.11be、802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等802.11家族的多种无线局域网(wireless local area networks,WLAN)制式的设备。
站点可以为无线通讯芯片、无线传感器或无线通信终端等,也可称为用户。例如,站点可以为支持WiFi通讯功能的移动电话、支持WiFi通讯功能的平板电脑、支持WiFi通讯功能的机顶盒、支持WiFi通讯功能的智能电视、支持WiFi通讯功能的智能可穿戴设备、支持WiFi通讯功能的车载通信设备和支持WiFi通讯功能的计算机等等。可选地,站点可以支持802.11be制式。站点也可以支持802.11be、802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等802.11家族的多种无线局域网(wireless local area networks,WLAN)制式。
例如,接入点和站点可以是应用于车联网中的设备,物联网(IoT,internet of things)中的物联网节点、传感器等,智慧家居中的智能摄像头,智能遥控器,智能水表电表,以及智慧城市中的传感器等。
其次,为便于理解本申请实施例的相关内容,对本申请实施例涉及的一些概念进行阐述。
本申请实施例中,触发帧中包括与所述站点的关联标识相同的多个用户信息字段,每个用户信息字段用于指示分配给所述站点的一个或多个资源单元;或者所述触发帧包括与所述站点的关联标识相同的一个用户信息字段,所述一个用户信息字段用于指示分配给所述站点的多个资源单元。
可选的,该触发帧的帧格式可如图2所示,图2是本申请实施例提供的一种触发帧的结构示意图,该触发帧中可只包括图2所示的部分字段,或触发帧中包括的字段可多于图2所示的字段,本申请实施例不做限定。
例如,该触发帧包括公共信息(common info)字段和用户信息列表(user info list)字段。该触发帧还可以包括帧控制(frame control)字段、时长(duration)字段、接收地址(RA)字段、发送地址(TA)字段、填充(padding)字段和帧校验序列(FCS,frame check sequence)字段等。
其中,公共信息字段也可以称为公共域或公共信息域。该公共信息字段包括触发帧类型(trigger type)子字段、长度(length)子字段、级联指示(cascade indication)子字段、需要载波侦听(CS Required)子字段、带宽(bandwidth)子字段、保护间隔+长训练序列(GI+LTF)子字段、基于触发帧类型的公共信息(trigger dependent common info)子字段等需要所有站点读取的公共信息。
其中,用户信息列表字段也可称为用户信息列表域、逐个站点域等。用户信息列表字段包括一个或多个用户信息(user info)字段,每个用户信息字段包括每个站点需要读取的信息,如关联标识(Association Identifier,AID)子字段、资源单元分配(RU allocation)子字段以及编码类型(coding type)子字段、调制编码策略(Modulation and Coding Scheme,MCS)子字段、预留(reserved)子字段、基于触发帧类型的用户信息(trigger dependent user info)子字段等。
其中,关联标识字段用于指示该用户信息字段所对应的站点的关联标识;资源单元分配子字段用于指示用户信息字段所指示的为该站点分配的资源单元(或资源单元位置)。本申请实施例中,用户信息字段可通过该资源单元分配子字段指示一个或多个资源单元,但也不限于该资源单元分配子字段。也就是说,用户信息字段包括的频带范围指示、资源单元指示和资源单元组合指示可部分或全部分布在该资源单元分配子字段中。
其中,本文所述的“字段(field)”也可称为“域”、“信息”等,“子字段(subfield)”可称为“子域”、“信息”等。图2所示的字段仅为举例,触发帧中也可以只包括图2所示的部分字段,或触发帧中包括的字段也可以多于图2所示的字段。
基于触发帧的调度式上行传输,即站点可以在分配的多个资源单元上发送数据分组,即物理层协议数据单元(physical layer protocol data unit,PPDU)。该数据分组可为高效基于触发的物理层协议数据单元(high efficient trigger based physical layer protocol data unit,HE TB PPDU)或极高吞吐率基于触发的物理层协议数据单元(Extremely High Throughput trigger based physical layer protocol data unit,EHT TB PPDU),该HE TB PPDU为高效物理层协议数据单元(high efficient physical layer protocol data unit,HE PPDU)中的一种。请参阅图3,图3是本申请实施例提供的一种基于触发帧的调度式上行传输的流程示意图。如图3所示,站点接收到触发帧后,可确定被分配的多个资源单元,从而在该多个资源单元 上发送PPDU。该PPDU的结构如图3所示,以STA 1发送PPDU为例,从HE-LTF到Data包括多个资源单元,传输STA1的上行数据。其中,该PPDU的各个字段的作用如表1所示。
表1
Figure PCTCN2021070882-appb-000001
在频域上将无线信道划分为多个子信道或子载波。图4是本申请实施例提供的一种信道分布示意图,如图4所示,该带宽为160MHz时可划分为主20MHz信道(或简称主信道,Primary 20MHz,P20),从20MHz信道(Secondary 20MHz,S20),从40MHz信道(Secondary 40MHz,S40),从80MHz(Secondary 80MHz,840)信道。其中,信道1可对应主20MHz信道、信道2对应从20MHz信道、信道3和信道4合并为从40MHz信道、信道5至信道8合并为从80MHz信道。
其中,信道中不同数量的子载波可组合成不同大小的资源单元。针对带宽为20MHz、40MHz、80MHz、160MHz或320MHz的情况,不同大小的资源单元可有以下七种:第一资源单元(包括996个子载波的资源单元,可称为996-tone RU)、第二资源单元(包括484个子载波的资源单元,可称为484-tone RU)、第三资源单元(包括484个子载波的资源单元,可称为484-tone RU)、第四资源单元(包括106个子载波的资源单元,可称为106-tone  RU)、第五资源单元(包括26个子载波的资源单元,可称为26-tone RU)、第六资源单元(包括52个子载波的资源单元,可称为52-tone RU)、第七资源单元(包括2*996个子载波的资源单元,可称为2*996-tone RU)。从而有利于接入点根据各站点的数据传输需求,为各站点分配多个资源单元进行上行数据传输。
请参阅图5,图5是本申请实施例提供的一种80MHz带宽可能的资源单元的分布示意图。如图5所示,第一行表示80MHz带宽可包括37个26-tone RU,第二行表示80MHz带宽可包括16个52-tone RU,第三行表示80MHz带宽可包括8个106-tone RU,第四行表示80MHz带宽可包括4个242-tone RU,第五行表示80MHz带宽可包括2个484-tone RU,第六行表示80MHz带宽可包括1个996-tone RU。如图5所示,20MHz的频带范围最多可以有9个资源单元,即9个26-tone RU。
请参阅图6,图6是本申请实施例提供的一种160MHz带宽可能的资源单元的分布示意图。如图6所示,第一行表示160MHz带宽可包括8个242-tone RU,第二行表示160MHz带宽可包括4个484-tone RU,第三行表示160MHz带宽可包括2个996-tone RU。
请参阅图7,图7是本申请实施例提供的一种320MHz带宽可能的资源单元的分布示意图。如图7所示,第一行表示320MHz带宽可包括4个996-tone RU。
其中,图5至图7中每行所示的资源单元并没有完全占用整个带宽,每行可包括一些剩余子载波用于资源单元之间的隔离。如图5所示,每20MHz的信道中具有2个子载波、1个子载波的间隔,484-tone RU与484-tone RU之间具有26个子载波的间隔。
其中,可能的资源单元的分布不限于上述图5至图7所示。例如,320MHz带宽可包括8个484-tone RU等。或者,320MHz带宽中每个80MHz的频带范围可采用图4所示的资源单元分布方式,160MHz带宽中每个80MHz的频带范围也可采用图4所示的资源单元分布方式。也就是说,本申请实施例不限定带宽可能的资源单元的分布,为便于理解本申请所述的资源分配方法,以图5至图7所示的分布为例,举例阐述为站点分配的多个资源单元有哪些,或分配的多个资源单元位置,或合并哪些资源单元,从而使得站点可在多个资源单元上进行上行数据传输。
下面结合附图,对本申请实施例所述的资源分配方法及相关设备进行阐述。其中,该资源分配方法也可以称为多资源单元指示方法或多资源单元的合并方法等。本申请实施例采用触发帧为站点分配多个资源单元。以下从两大方面进行阐述。其中,第一方面,触发帧通过多个用户信息字段,指示为站点分配的多个资源单元;也就是说,触发帧中包括与站点的关联标识相同的多个用户信息(user info)字段。第二方面,触发帧通过一个用户信息字段,指示为站点分配的多个资源单元;也就是说,触发帧中包括与站点的关联标识相同的一个用户信息(user info)字段。
一、该触发帧中包括与站点的关联标识相同的多个用户信息(user info)字段
其中,每个用户信息(user info)字段可指示一个或多个资源单元,该多个用户信息字段分别所指示的资源单元为分配给该站点的多个资源单元。
基于该触发帧的设计,请参阅图8,图8是本申请实施例提供的一种资源分配方法的流程示意图。如图8所示,该资源分配方法包括以下步骤:
101、接入点确定分配给站点的多个资源单元;
102、接入点向所述站点发送触发帧,该触发帧中包括与本站点的关联标识相同的多个用户信息字段,每个用户信息字段用于指示分配给所述站点的一个或多个资源单元;
103、站点接收该触发帧,并根据该触发帧确定被分配的多个资源单元。
其中,所述站点根据所述触发帧确定被分配的多个资源单元,包括:
1031、所述站点从所述触发帧中,选择与所述站点的关联标识相同的一个或多个用户信息字段;
1032、针对选择的一个或多个用户信息字段中的每个用户信息字段,所述站点确定所述用户信息字段所指示的一个或多个资源单元;所述选择的一个或多个用户信息字段所分别指示的一个或多个资源单元为所述站点被分配的多个资源单元。
可选地,以图2所示的帧结构为例,用户信息字段分布在用户信息列表字段中,故站点可从用户信息列表字段中选择与所述站点的关联标识相同的一个或多个用户信息字段。也就是说,站点接收用户信息列表字段,解析其中的关联标识字段所指示的关联标识,选择与本站点的关联标识相同的多个用户信息字段。
针对步骤1031中,站点如何从触发帧中选择与该站点的关联标识相同的多个用户信息字段,可以采用以下几种可选的实施方式,但不限于以下所述的实施方式。例如,可同时采用以下实施方式中的一种或多种以选择出该多个用户信息字段。
1.1、触发帧中所有的用户信息字段解析完毕
该实施方式中,针对触发帧中的所有用户信息字段,站点可分别解析每个用户信息字段中关联标识字段所指示的关联标识;从解析的所有用户信息字段中,选择与本站点的关联标识相同的多个用户信息字段。其中,如图2所示,触发帧中的用户信息列表字段具有边界,从而使得本站点可根据该边界解析所有用户信息字段。
为阐述方便,本文可将“与站点的关联标识相同的多个用户信息字段”称为本站点的用户信息字段,或本站点匹配的用户信息字段,或本站点的用户信息字段等。
其中,该触发帧中本站点对应的多个用户信息字段可连续出现,也可不连续出现。例如,假设用户信息列表字段包括M个用户信息字段,STA 1的关联标识为AID1,图9中STA 1对应的用户信息字段在用户信息列表中连续出现,即该用户信息列表字段中前两个用户信息字段为STA1对应的用户信息字段,第3至M个用户信息字段不为STA1对应的用户信息字段。图10中STA 1对应的用户信息字段在用户信息列表字段中不连续出现,即STA1对应的用户信息字段可为用户信息列表字段中的第1个用户信息字段、第3个用户信息字段,等等。可见,针对图9、图10所示的用户信息列表字段,该实施方式中站点可通过一一解析的方式,确定与本站点的关联标识相同的多个用户信息字段。
1.2、协议预定义或通过信令为站点配置,触发帧中本站点的用户信息字段的个数N
该实施方式中,站点可基于该N从触发帧的用户信息列表字段中,选择N个自身的用户信息字段。
具体的,站点从触发帧中选择与该站点的关联标识相同的多个用户信息字段,可包括:站点根据所述用户信息列表字段中各用户信息字段的索引,解析并判断所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同,直至与所述站点的关 联标识相同的用户信息字段的个数等于N时,停止执行所述的解析所述的关联标识相同的步骤;从解析的各用户信息字段中,选择与所述站点的关联标识相同的N个用户信息字段。可见,该实施方式在保证用户信息字段部署灵活性的同时,降低站点解析该用户信息列表字段的复杂度。
例如,图9所示的用户信息列表字段,若用户信息列表字段中STA 1的用户信息字段的个数等于2,即N=2,则STA 1可在解析了第2个用户信息字段,判断出STA1的两个用户信息字段时,停止解析该用户信息列表字段。
再例如,图10所示的用户信息列表字段,若用户信息列表字段中STA 1的用户信息字段的个数的最大值等于2,即N=2,则STA 1可在解析了第3个用户信息字段,判断出STA1的两个用户信息字段时,停止解析该用户信息列表字段。
可选的,若协议预定义的,或接入点通过信令为站点配置的,或接入点计算的用户信息列表字段中该站点的用户信息字段的个数N。例如,假设每个用户信息字段所能指示的资源单元的个数为1个,则N可等于协议预定义的或通过信令为站点配置的能够分配的资源单元的个数。
1.3、触发帧中同一站点的用户信息字段连续分布
也就是说,不同的站点的用户信息字段在用户信息列表字段中分别是连续分布的。如图9所示,STA1的用户信息字段在用户信息列表字段分布结束后,再分布STA2的用户信息字段。
该实施方式中,103中从用户信息列表字段中选择与本站点的关联标识相同的多个用户信息字段,可包括:所述站点以所述用户信息列表字段中解析的与本站点的关联标识相同的第一个用户信息字段为起始,根据各用户信息字段的索引,依次解析并判断用户信息字段中关联标识字段指示的关联标识是否与本站点的关联标识相同,直至解析并判断到与本站点的关联标识不同的用户信息字段为止;从解析的各用户信息字段中,选择与所述站点的关联标识相同的多个用户信息字段。可见,该实施方式能够降低站点解析用户信息列表字段所需的复杂度。
例如,如图9所示,STA1、STA2的用户信息字段在用户信息列表字段中分别是连续分布的,一旦开始分布STA 2的用户信息字段,则表示STA 1的用户信息字段分布结束。这样,STA1解析并判断了第2个用户信息字段后,在继续解析第3个用户信息字段,判断该第3个用户信息字段不是自身的用户信息字段后,可停止解析后续的用户信息字段,即不再解析用户信息列表字段。
1.4、用户信息字段包括结束标志
也就是说,如图11所示,图11是本申请实施例提供的又一种用户信息列表字段的结构示意图。图11中,用户信息字段中还包括结束标志,该结束标志用于指示站点的资源单元分配是否结束。
该结束标志可占用1个比特,该1个比特可为用户信息字段中预留字段中的一个比特,或用户信息字段中新添加的一个比特,或复用其他信息的一个比特,本申请实施例不做限定。
该结束标志也可称为结束标志域、结束标志信息、结束标志指示、结束标志等。该结 束标志的值为1可表示所在的用户信息字段的站点的资源单元分配结束;该结束标志的值为0可表示所在的用户信息字段的站点的资源单元分配未结束,该站点还需解析下一个用户信息字段,反之也可以。
该实施方式中,所述站点从用户信息列表字段中选择与该站点的关联标识相同的多个用户信息字段,可包括:所述站点根据所述触发帧中各用户信息字段的索引,依次解析所述各用户信息字段中关联标识字段指示的关联标识是否与所述站点的关联标识相同,直至所解析的用户信息字段中结束标志指示所述站点的资源单元分配结束时,停止执行所述的解析关联标识相同的步骤;从解析的各用户信息字段中,选择与所述站点的关联标识相同的多个用户信息字段。
假设结束标志的值为1表示其所在的用户信息字段的站点的资源单元分配结束。如图9所示,若第2个用户信息字段为STA 1分配资源单元的最后一个用户信息字段,则AP可在该第2个用户信息字段中,将结束标志设置为1。这样,站点可在解析该第2个用户信息字段时,读取该结束标志字段为1可停止解析该用户信息列表字段,即不需解析第3个用户信息字段及其之后的用户信息字段。相应的,由于第1个用户信息字段不是为STA 1分配资源单元的最后一个用户信息字段,故该第1个用户信息字段中结束标志的值可设置为0。这样,STA 1在解读并判断第1个用户信息字段后,可继续解析并判断第2个用户信息字段。
如图10所示,若第3个用户信息字段为STA 1分配资源单元的最后一个用户信息字段,则AP可在该第3个用户信息字段中,将结束标志设置为1。这样,站点可在解析该第3个用户信息字段,读取该结束标志字段为1时,停止解析并判断该用户信息列表字段,即不需解析第3个用户信息字段及其之后的用户信息字段。相应的,由于第1个用户信息字段不是为STA 1分配资源单元的最后一个用户信息字段,故该第1个用户信息字段中结束标志的值可设置为0。这样,STA 1在解读并判断第1个用户信息字段后,可继续解析并判断第2个用户信息字段。另外,图10中,STA 1在解析第2个用户信息字段后,判断该第2个用户信息字段不是STA 1的用户信息字段,可继续解析并判断第3个用户信息字段。
另外,针对站点如何从用户信息列表字段中选择该站点的多个用户信息字段的方法,可包括上述1.1-1.4所述的实施方式中的任一种或多种,但也不限于这些实施方式。
针对选择的多个用户信息字段,站点如何确定每个用户信息字段指示的一个或多个资源单元,本申请实施例可从以下几种可选的实施方式进行阐述,但不限于以下所述的实施方式。
2.1、每个用户信息字段指示一个资源单元
用户信息字段可指示一个资源单元,例如,采用图2所示的资源单元分配子字段指示该资源单元。即用户信息字段包括的资源单元指示和频带范围指示,可包含在资源单元分配子字段中。
可见,该实施方式中无论资源单元合并跨越的带宽大小有多大,需要多少个RU,均可采用同样数量的用户信息字段分别指示同样数量的RU即可。
该实施方式可通过协议预定义或信令配置的方式告知站点,各资源单元与索引之间的 对应关系。AP可通过资源单元分配子字段指示其中一个索引,使得站点可根据该资源单元分配子字段所指示的索引,确定对应的一个资源单元。
无线局域网的带宽可包括20MHz、40MHz、80MHz、160MHz、240MHz、320MHz等,对于20MHz、40MHz、80MHz的带宽,AP为站点分配资源单元时,可利用资源单元分配子字段直接指示该带宽中的其中一个资源单元;对于大于或等于160MHz的带宽,如160MHz、240MHz、320MHz等,AP还需利用资源单元分配子字段指示资源单元在该带宽中的哪一个80MHz中。因此,该资源单元分配子字段可包括:频带范围指示和资源单元指示。
频带范围指示用于指示资源单元指示所指示的资源单元所在的频带范围;资源单元指示用于指示分配的一个资源单元。可选的,若资源单元指示所指示的资源单元的大小大于80MHz,或资源单元指示所指示的资源单元包括的子载波个数大于996,如2*996-tone RU,那么该频带范围指示可忽略,即站点不需要解读该频带范围指示。
请参见表2,表2是本申请实施例提供的一种频带范围指示的值、带宽、频带范围三者之间的关系。如表2所示,对于20MHz、40MHz、80MHz的带宽,该资源单元分配子字段可不包括频带范围指示。对于160MHz的带宽,该资源单元分配子字段中频带范围指示可占用1个比特,即需要的比特数为1;该频带范围指示等于0表示:资源单元指示所指示的资源单元位于该带宽中的主80MHz中,或资源单元指示所指示的资源单元为主80MHz中的一个资源单元;该频带范围指示等于1表示:资源单元指示所指示的资源单元位于该带宽中的从80MHz中,或资源单元指示所指示的资源单元为从80MHz中的一个资源单元。对于320MHz的带宽,该资源单元分配子字段中频带范围指示可占用2个比特,即需要的比特数为2;该频带范围指示等于0表示:资源单元指示所指示的资源单元位于该带宽中的主80MHz中,或资源单元指示所指示的资源单元为主80MHz中的一个资源单元;该频带范围指示等于1表示:资源单元指示所指示的资源单元位于该带宽中的从80MHz中,或资源单元指示所指示的资源单元为从80MHz中的一个资源单元;该频带范围指示等于3表示:资源单元指示所指示的资源单元位于该带宽中的第三个80MHz中,或资源单元指示所指示的资源单元为第三个80MHz中的一个资源单元;该频带范围指示等于4表示:资源单元指示所指示的资源单元位于该带宽中的第四个80MHz中,或资源单元指示所指示的资源单元为第四个80MHz中的一个资源单元。另外,表2中频带范围指示的各值与各80MHz频带范围之间的对应关系可调整,本申请实施例不做限定。
表2

Figure PCTCN2021070882-appb-000003
资源单元指示用于指示一个资源单元。该资源单元的大小可包括但不限于上文所述的七种。结合图5所示的80MHz中资源单元的分布示意图,如图5所示,80MHz的频带范围可包括37个位于不同位置的26-tone RU、或16个位于不同位置的52-tone RU,或8个位于不同位置的106-tone RU,或4个位于不同位置的242-tone RU,或2个位于不同位置的484-tone RU,或1个996-tone RU。另外,该资源单元指示还可以指示2*996-tone RU。因此,资源单元指示的值或资源单元指示所指示的索引至少从0至68,以能够分别指示上述所述的68个资源单元。
请参见表3,表3为资源单元指示的值、各资源单元之间的对应关系。为了指示上述所述的68个资源单元,资源单元指示至少需要7个比特,故该7个比特的值0-68可如表3所示分别指示各资源单元,69-127可预留(reserved)。另外,表3中各值与所指示的资源单元之间的对应关系可调整,本申请实施例不做限定。例如,资源单元指示的值可从大到小分别指示从大到小排列的资源单元,等等。其中,表3所述的相关内容可包括权利要求书中权利要求13的相关文字表述。也就是说,说明书中阐述是将第一资源单元至第七资源单元替换为对应的大小的资源单元,如第一资源单元为996-tone RU、第二资源单元484-tone RU、第三资源单元为242-tone RU,等等。类似,表2至表13中的各描述也是采用对应的RU进行阐述的,包括相应权利要求的内容。
表3
Figure PCTCN2021070882-appb-000004
Figure PCTCN2021070882-appb-000005
该实施方式中,频带范围指示用于指示带宽中某一个80MHz的频带范围;资源单元指示用于指示一个资源单元,该资源单元可为80MHz的频带范围中的任一个资源单元或大于80MHz的资源单元。也就是说,每个用户信息字段可指示某一个80MHz的频带范围中的 任一个资源单元或大于80MHz的资源单元。因此,本申请实施例可针对103选择的多个用户信息字段,利用每个用户信息字段中的资源单元分配子字段可确定一个资源单元。那么,该多个用户信息字段所分别指示的资源单元为分配给站点的多个资源单元。
其中,若带宽为20MHz、40MHz、80MHz,则该实施方式中,频带范围指示可默认为0,针对站点的每个用户信息字段,站点可根据资源单元指示确定一资源单元。若带宽为160MHz、320MHz,频带范围指示可占用1个比特或2个比特,针对站点的每个用户信息字段,站点可根据频带范围指示确定一80MHz频带范围,再根据资源单元指示从该80MHz频带范围中确定对应的资源单元。
假设无论带宽多大,频带范围指示占用2个比特,为资源单元分配子字段中的高两位;资源单元指示占用7个比特,为资源单元分配子字段中的低7位;以及表3中资源单元指示的各值以从小到大的顺序依次与图3中每行RU中从左到右的RU一一对应。
为便于举例阐述,以下结合附图阐述部分可能的RU合并方案。
以图12至图17为例,阐述80MHz内,某一个20MHz中52-tone RU与26-tone RU的合并方案,即分配给一个站点的52-tone RU、26-tone RU。
80MHz频带范围中某一个20MHz中,次低频率的52-tone RU与该20MHz中同侧相邻的26-tone RU的合并方案。其中,“同侧相邻”与该20MHz在该80MHz频带范围中的位置有关,若该20MHz在该80MHz频带范围内中心位置的左侧,则该“同侧相邻”为“左侧相邻”,若该20MHz在该80MHz频带范围内中心位置的右侧,则该“同侧相邻”为“右侧相邻”。
本文中,次低频率的RU、最低频率的RU、次高频率的RU、最高频率的RU均是相对于一个频率范围而言的。例如,如图5所示,第一个20MHz内,次低频率的52-tone RU是指图5中第二行的第二个52-tone RU,最低频率的52-tone RU是指图5中第二行的第一个52-tone RU,次高频率的52-tone RU是指图5中第二行的第三个52-tone RU,最高频率的52-tone RU是指图5中第二行的第四个52-tone RU。相应地,对于其他RU而言,次低频率的RU、最低频率的RU、次高频率的RU、最高频率的RU类似,此处不再详述。另外,本文中低频率的RU,高频率的RU也是相对于一个频率范围而言的。其中,该频率范围中该RU的个数一般为两个,低频率的RU是指两者中位于相对较低频率的RU,高频率的RU是指两者中位于相对较高频率的RU。例如,图5所示,第一个20MHz内,低频率的106-tone RU是指图5中第三行的第一个106-tone RU,高频率的106-tone RU是指图5中第三行的第二个106-tone RU。

由于一个80MHz中484-tone RU、242-tone RU的选择方案有4种,如图20-图23,频带范围指示所指示的某一个80MHz与其相邻的80MHz有两个80MHz,故4*4,即484-tone RU、242-tone RU、484-tone RU、242-tone RU的合并方案可包括16种,在此不一一展开阐述。

请参阅图37,图37为本申请实施例提供的两个996-tone RU的一种合并示意图。图37所示的RU分布为320MHz内的RU分布。该320MHz内,频带范围指示所指示的某一个80MHz(如第一个80MHz)对应的一个996-tone RU,与除其之外的第一个80MHz对应的996-tone RU的合并示意图如图37所示。

请参阅图39,图39为本申请实施例提供的两个996-tone RU的另一种合并示意图。图39所示的RU分布为320MHz内的RU分布。该320MHz内,频带范围指示所指示的某一个80MHz(如第一个80MHz)对应的一个996-tone RU,与除其之外的第三个80MHz对应的996-tone RU的合并示意图如图39所示。
上述图12至图39阐述了部分可能的RU合并示意图,本申请所述的资源分配方法以图12至图39所示的RU合并方案为例,阐述如何指示给站点,从而实现站点的多个资源单元分配。
可选的,图12至图39所述的RU合并方案可适用于上行传输中资源单元配置中,也可适用于PPDU传输中资源单元的配置,如单用户协议数据单元(Single User PPDU,SU PPDU),多用户协议数据单元(Multiple User PPDU,MU PPDU),扩展距离协议数据单元(Extended Range PPDU,ER SU PPDU)中资源单元的配置。
针对该部分所述的实施方式中,用户信息列表字段中包括与站点的关联标识相同的多个用户信息字段,每个用户信息字段用于指示一个资源单元的情况,资源单元分配子字段中的频带范围指示可用于指示带宽中的某一个80MHz,资源单元指示可利用表3所示的对应关系指示其中一个资源单元。
例如,图9所示的用户信息列表字段中,AP将第1个用户信息字段中的资源单元分配子字段设置为000000001,那么,STA 1解读该第1个用户信息字段可确定资源单元分配子字段中的频带范围指示(高比特位00)所指示的是第一个80MHz,资源单元指示(低比特位0000001)所指示的是图3中第一行的第2个26-tone RU。另外,AP将第2个用户信息字段中资源单元分配子字段设置000100110,那么,STA 1解读该第2个用户信息字段可确定资源单元分配子字段中的频带范围指示(高比特位00)所指示的是第一个80MHz,资源单元指示(低比特位0100110)所指示的是图5中第二行的第2个52-tone RU。由于STA 1可基于1.1-1.4所述的实施方式确定用户信息列表字段中没有自己的用户信息字段了,故STA 1可最终确定自身被分配的多个RU分别是图5中第一行的第2个26-tone RU和图5中第二行的第2个52-tone RU。
同理,图12至图26所示的两个资源单元的合并方案、图37至图39所示的两个资源单元的合并方案,也可以基于表2、表3所示的对应关系进行指示,从而站点能够获得被分配的多个资源单元,此处不再一一详述。
对于图27至图34所示的三个资源单元的合并方案,用户信息列表字段中可包括与站点相同的三个用户信息字段,从而可利用该三个用户信息字段,以及表2、表3所示的对应关系,分别确定每个资源单元分配子字段中频带范围指示的值和资源单元分配指示的值。相应的,站点可采用1.1部分至1.4部分所示的实施方式从该用户信息列表字段中获取自身的三个用户信息字段;进而基于该实施方式中表2、表3以及每个用户信息字段中的值确定被分配的三个资源单元。
实施本实施例,通过使用用户信息字段将多个RU分配给单个站点,站点能够正确解密RU分配信息,有利地实现与传统接收STA的向后兼容性。
2.2、单个用户信息字段指示多个资源单元
一种情况,采用每80MHz需要一个用户信息字段指示的方式,那么对于大于80MHz以及小于或等于160MHz的RU合并情况,最多需要两个用户信息字段即可,对于大于160MHz以及小于或等于320MHz的RU合并情况,最多需要四个用户信息字段即可。其中,80MHz内多RU的合并情况,即可采用本实施方式,利用一个用户信息字段进行指示。
另一种情况,采用每160MHz需要一个用户信息字段指示的方式,那么对于小于或等于160MHz的RU合并情况,最多需要一个用户信息字段即可,对于大于160MHz以及小于或等于320MHz的RU合并情况,最多需要两个用户信息字段即可。其中,对于小于或等于160MHz内多RU的合并情况,可采用本实施方式,利用一个用户信息字段指示该160MHz内多RU的合并。
对于160MHz内4个RU合并的情况,如484-tone RU、242-tone RU、484-tone RU和242-tone RU合并,这种情况需要每一个80MHz使用一个用户信息字段来指示其中的一个484-tone RU和242-tone RU的合并,那么可采用两个用户信息字段来指示该合并的情况。
另外,对于三个996-tone RU合并的情况,每个996-tone RU采用一个用户信息字段进行指示,可需要三个用户信息字段指示该三个996-tone RU合并的情况。
可选的,无论资源单元合并跨越的带宽大小有多大,若不限定一个用户信息字段能够指示的带宽大小范围,则可采用一个用户信息字段指示多个资源单元。
2.2.1单个用户信息字段指示的多个资源单元与各索引之间的对应关系
该实施方式中,资源单元分配子字段中资源单元指示可指示多个资源单元(为阐述方便,下文阐述为合并的多个资源单元)。可通过协议预定义或信令配置的方式告知站点,各种可能的合并的多个资源单元与各索引之间的对应关系。AP可通过资源单元指示以指示其中一个索引,使得站点可根据该资源单元指示所指示的索引,确定合并的多个资源单元。
也就是说,与实施方式2.1不同之处在于,该实施方式2.2中,资源单元指示用于指示合并的多个资源单元。请参见表4,表4包括表3所示的对应关系,并补充了资源单元指示的值为69-127所表示的含义,即用于指示合并的多个资源单元。
表4资源单元指示的值与“资源单元或合并的多个资源单元”之间的对应关系

一种可选的实施方式中,所述资源单元分配子字段包括资源单元指示,所述资源单元指示用于指示多个资源单元。如表4中,资源单元指示所指示的值或索引为71、107-110时,站点可不解读频带范围指示所指示的是哪一个80MHz。
相应的,步骤104中,所述站点根据所述资源单元分配子字段确定每个所述用户信息字段所指示的多个资源单元,包括:针对每个所述用户信息字段,所述站点确定所述资源单元指示所指示的多个资源单元,为所述用户信息字段所指示的多个资源单元。
另一种可选的实施方式中,所述资源单元分配子字段包括资源单元指示和频带范围指示。该频带范围指示用于指示某一个80MHz;资源单元指示用于指示多个资源单元。相应的,步骤104中,针对每个所述用户信息字段,所述站点根据所述资源单元分配子字段确定用户信息字段所指示的多个资源单元,包括:所述站点确定所述频带范围指示所指示的频带范围;所述站点根据所述资源单元指示,确定所述频带范围中的两个资源单元,以及与所述频带范围低频相邻的或高频相邻的频带范围中的两个资源单元;将确定的四个资源单元作为所述用户信息字段所指示的多个资源单元。
例如,表4中,资源单元指示所指示的值或索引为111-126的情况,站点根据频带范围指示所指示的频带范围后,还需确定与该频带范围低频相邻或高频相邻的另一80Mhz的频带范围,进而根据该资源单元指示所指示的索引,确定合并的多个资源单元。
又一种可选的实施方式中,步骤104中,所述站点根据所述资源单元分配子字段确定每个所述用户信息字段所指示的多个资源单元,包括:针对每个所述用户信息字段,所述站点确定所述频带范围指示所指示的频带范围;所述站点确定所述资源单元指示所指示的多个资源单元为:所述频带范围对应的资源单元、以及与该频带范围对应的资源单元相邻的频带范围中的一个或多个资源单元。例如,表4中,资源单元指示所指示的值或索引为68-70、101-106的情况,站点可采用该实施方式确定该用户信息字段所指示的多个资源单元。
又一种可选的实施方式中,步骤104中,针对每个所述用户信息字段,站点根据所述资源单元分配子字段确定每个所述用户信息字段所指示的多个资源单元,包括:站点确定频带范围指示所指示的频带范围,以及从该所述频带范围中确定所述资源单元指示所指示的多个资源单元。例如,表4中,资源单元指示所指示的值或索引为72-100时,站点可采用该实施方式确定该用户信息字段所指示的多个资源单元。
可见,该2.2.1部分是通过频带范围指示、资源单元指示以及表4的相关内容为站点分配资源单元,不需要增加新的比特,有利于降低资源开销。
2.2.2、用户信息字段包括频带范围指示、资源单元指示以及资源单元组合指示
该实施方式中,用户信息字段通过上述三个指示也可以指示多个资源单元。其中,频 带范围指示用于指示哪一个80MHz的频带范围,可选的取值或索引如表2所示,此处不再详述。资源单元指示用于指示频带范围中的一个资源单元,可选的取值或索引如表3所示,此处不再详述。资源单元组合指示用于指示合并的多个资源单元,合并的多个资源单元包括所述资源单元指示所指示的资源单元。该合并的多个资源单元作为所述用户信息字段所指示的多个资源单元。其中,资源单元组合(RU combination)指示也可称为资源单元组合域、资源单元组合字段、合并域或合并字段等。
其中,资源单元组合指示可占用1个、2个或3个比特等。可选的,该资源单元组合指示所占的比特数与资源单元的合并方案的个数有关。该资源单元的合并方案为:资源单元指示所指示的资源单元的合并方案。另外,资源单元组合指示所占的比特的位置不限,可连续或不连续。
该资源单元组合指示所占的比特可以在用户信息字段中新增、利用预留的字段或复用其他信息字段等。例如,图40为本申请实施例提供的一种用户信息字段的结构示意图,如图40所示,基于触发帧类型的站点信息字段包括多用户空间因子(MPDU MU Spacing Factor)、通信标识符聚合限制(TID Aggregation Limit)、资源单元组合指示比特1(RU Combination Bit 1)、优选的接入类别(Preferred AC)。资源单元组合指示占用两个比特,资源单元组合指示比特0可采用如图2所示的用户信息字段中的预留比特,资源单元组合指示比特1可以为如图40所示的用户信息字段中基于触发帧类型的站点信息字段中的一个比特。
图40所示的结构中,资源单元分配子字段(即频带范围指示和资源单元指示)和资源单元组合指示为独立的两个字段;另一种实现方式中,所述资源单元分配子字段和资源单元组合指示可以合并成一个字段,也即通过一个字段实现频带范围指示、资源单元指示和资源单元组合指示中的多个功能,该一个字段可以用原资源单元分配子字段扩展后实现,也可以用预留的比特实现。
相应的,站点确定所述用户信息字段所指示的多个资源单元,包括:所述站点根据所述资源单元组合指示和所述资源单元指示所指示的资源单元,确定合并的多个资源单元,作为所述用户信息字段所指示的多个资源单元。
以资源单元组合指示占用2个比特,以及图18、图19所示的106-tone RU、26-tone RU合并方案为例,资源单元指示可利用表2、表3指示某一个106-tone RU,该资源单元组合指示的值或索引与各描述或含义之间的对应关系如表5所示。
例如,频带范围指示为00,资源单元指示为53,则根据表2、表3可知,资源单元指示所指示的资源单元为图5中第三行的第一个106-tone RU,那么资源单元组合指示为01时,该用户信息字段指示多个RU,且该多个RU为:图5中第三行的第一个106-tone RU以及图3中第一行的第5个26-tone RU,如图18所示。
再例如,频带范围指示为00,资源单元指示为54,则根据表2、表3可知,资源单元指示所指示的资源单元为图5中第三行的第二个106-tone RU,那么资源单元组合指示为01时,该用户信息字段指示多个RU,且该多个RU为:图5中第三行的第二个106-tone RU以及图3中第一行的第5个26-tone RU,如图19所示。

以资源单元组合指示占用2个比特,以及图12至图17所示的52-tone RU、26-tone RU合并方案为例,资源单元指示可利用表2、表3指示某一个52-tone RU,该资源单元组合指示的值或索引与各描述或含义之间的对应关系如表6所示。其中,“同侧相邻”可参见图12至图17所述部分的阐述,此处不再详述。
例如,资源单元指示可利用表2、表3指示图5中第二行第二个52-tone RU,即频带范围指示为00,资源单元指示为38,若资源单元组合指示为01,该用户信息字段指示多个RU,且该多个RU为:图5中第二行的第二个52-tone RU以及图3中第一行的第5个26-tone RU,如图16所示。若资源单元组合指示为10,该用户信息字段指示多个RU,且该多个RU为:图5中第二行的第二个52-tone RU以及图5中第一行的第二个26-tone RU,如图12所示。
针对其他的52-tone RU、26-tone RU合并方案可采用相似的指示方式,从而站点可根据该三个指示确定该用户信息字段所指示的多个资源单元。

例如,资源单元指示可利用表2、表3指示图5中第五行第一个484-tone RU,即频带范围指示为00,资源单元指示为65,若资源单元组合指示为01,该用户信息字段指示多个RU为:图5中第五行的第一个484-tone RU以及图3中第四行的第三个242-tone RU,如图20所示。若资源单元组合指示为10,该用户信息字段指示多个RU为:图5中第五行的第一个484-tone RU以及图5中第四行的第四个26-tone RU,如图22所示。

可见,该实施方式针对多个资源单元分配给一个站点的情况,触发帧中不需要两个用户信息字段来指示,只需一个用户信息字段即可完成指示。即在站点所需分配的一个资源单元对应的用户信息字段,或站点对应的一个用户信息字段即可完成多个RU合并分配的指示。
可见,资源单元组合指示可基于RU的合并方案以及选择的灵活性确定其所占的比特数。该实施方式无论带宽多大,可采用一个用户信息字段指示多个资源单元的合并,或者针对大带宽,可采用两个用户信息字段分别指示每个用户信息字段所对应的80MHz中RU的组合方案。上述第一部分讲述了该用户信息列表(user info list)字段中包括与站点的关联标识相同的多个用户信息(user info)字段如何选择,或可选的实施方式;以及讲述了针对多个用户信息字段,每个用户信息字段可通过上述实施方式2.1指示一个资源单元,或可通过上述实施方式2.2.1、实施方式2.2.2指示合并的多个资源单元。从而,该部分可为站点分配多个资源单元。
二、触发帧中包括与站点的关联标识相同的一个用户信息字段
该实施方式采用一个用户信息字段,即可为站点配置多个资源单元。其中,该用户信息字段可采用上述实施方式2.2.1、实施方式2.2.2,以指示多个资源单元。
该用户信息字段可包括:频带范围指示和资源单元指示。或者,该用户信息字段可包括:频带范围指示、资源单元指示以及资源单元组合指示。
请参阅图41,图41是本申请实施例提供的一种资源分配方法的流程示意图。如图41所示,该资源分配方法包括以下步骤:
201、接入点确定分配站点的多个资源单元;
202、接入点发送该触发帧;该触发帧中包括与站点的关联标识相同的一个用户信息字段,该用户信息字段用于指示分配给所述站点的多个资源单元;
203、站点接收该触发帧,并根据该触发帧确定被分配的多个资源单元。
其中,站点根据该触发帧确定被分配的多个资源单元,包括:站点从用户信息列表字段中选择关联标识字段所指示的关联标识,与该站点的关联标识相同的一个用户信息字段;站点确定该用户信息字段所指示的多个资源单元,该用户信息字段所指示的多个资源单元为分配给该站点的多个资源单元。
站点如何从用户信息列表字段中选择与该站点的关联标识相同的一个用户信息字段,可以采用上述实施方式1.1至实施方式1.4可选的实施方式,但不限于以上所述的实施方式。
站点如何确定资源单元分配子字段所指示的多个资源单元,可参见上述实施方式2.2.1、实施方式2.2.2的相关阐述,此处不再详述。
本申请实施例中,无论RU合并跨越的带宽大小有多大,若不限定一个用户信息字段能够指示的RU合并的范围,则可采用一个用户信息字段来指示各RU的合并方案。
例如,对于80MHz内的多RU合并的情况,可采用上述实施方式2.2.1所述的用户信息字段进行指示,如表4中资源单元指示的值为72-100,可指示的RU合并方案;或者可采用上述实施方式2.2.2所述的用户信息字段进行指示,如表5所示,106tone RU与26tone RU之间的合并;如表6所示52tone RU与26tone RU之间的合并;如表7所示484-tone RU、242-tone RU之间的合并;如表8所示242-tone RU与242-tone RU合并,等等。
对于大于80MHz,但小于或等于160MHz的RU合并的情况,可采用上述实施方式2.2.1所述的用户信息字段进行指示,如表4中资源单元指示的值为101至106时,可指示该范围内RU的合并方案。或者,对于大于80MHz,但小于或等于160MHz的RU合并的情况,可采用上述实施方式2.2.2所述的用户信息字段进行指示,如表9所示,可采用一个用户信息字段中频带范围指示和资源单元指示指示一个996-tone RU,再采用资源单元组合指示来指示该996-tone RU可能的合并方案。
对于大于160MHz,但小于或等于320MHz的RU合并的情况,可采用上述实施方式2.2.1所述的用户信息字段进行指示,如表4中资源单元指示的值为107至110时,可指示该范围内RU的合并方案。
或者对于大于80MHz的RU合并的情况,可采用上述实施方式2.2.2所述的用户信息字段进行指示。如表10所示的方案进行指示,该情况下资源单元组合指示可占用3个比特,需要用户信息字段中新引入1比特以组成3比特的资源单元组合指示,例如在大于80MHz下可复用上行双载波调制字段,作为资源单元组合指示。
可见,对于实施方式2.2.2来说,对于小于或等于80MHz的情形,资源单元组合指示可以使用2比特或1比特指示的方法,如表5至表8、表11至表13。对于大于80MHz但是小于或等于160MHz的RU合并情形,资源单元组合指示需要2比特指示,如表9所示,可在该站点所需要分配的996-tone RU对应的用户信息字段中进行指示即可。对于大于80MHz的RU合并情形,资源单元组合指示需要3比特指示,如表10所示。
可选的,表10中可要求在大于80MHz的多RU合并中,资源单元指示可用于指示频率最低的996-tone RU。
可见,图41所示的资源分配方法中,可采用一个用户信息字段为站点配置多个资源单元,从而能够降低用户信息字段的开销。
另外,本文中,上述两部分所述的资源分配方法可应用于同一网络结构中,比如可根据各站点所需传输的数据量或数据的优先级等,分别为部分站点配置合并的多RU,为部分站点配置一个RU等等,本申请实施例不做限定。上述两部分所述的资源分配方法可应用于同一站点中,比如可根据站点不同时刻所需传输的数据量或数据的优先级的不同等,分别为该站点配置合并的多RU或一个RU等等,本申请实施例不做限定。
综上所述,本申请提供了一种资源分配方法,接入点给站点发送的该触发帧中包括与该站点的关联标识相同的多个用户信息字段,每个用户信息字段可用于指示为站点分配的一个资源单元,从而能够为站点分配多个资源单元,如上述实施方式2.1部分所述的相关内容。
另一资源分配方法中,该触发帧中包括与该站点的关联标识相同的一个用户信息字段,该用户信息字段可用于指示为站点分配的多个资源单元,从而实现为站点分配多个资源单元,能够减少用户信息字段的使用。该用户信息字段可采用实施方式2.2.1部分的所述,利用表2、表3,资源单元指示和频带范围指示能够指示多个资源单元。该用户信息字段可重新设计,如实施方式2.2.2部分的所述,在用户信息字段中增加资源单元组合指示,即重新设计触发帧中的资源单元分配子字段,通过复用其他信息字段或预留字段,或新增比特的方式设置资源单元组合指示,以指示合并的多个资源单元,作为用户信息字段指示的资源单元。
又一种资源分配方法中,该触发帧中包括与该站点的关联标识相同的多个用户信息字段,每个用户信息字段可用于指示为站点分配的多个资源单元如实施方式2.2.1、实施方式2.2.2。可见,该方法能够在一个用户信息字段所指示的RU合并所跨越的带宽大小被限制的情况下,也能够为站点分配更多的资源单元。
三、下行传输中资源单元的分配方法
本申请还提供了一种资源单元分配方法,该资源单元分配方法是为站点分配下行传输所占的资源单元。接入点可向站点发送PPDU前导消息,如图42所示,该PPDU前导消息中包括用户信息字段(User Specific field)和公共字段(Common field)。其中,公共字段用于指示RU分配信息;用户信息字段由一系列用户字段(User field)构成。需要说明的是,此处用户信息字段是下行传输中PPDU前导消息中的字段,不同于上述实施例中上行传输中的用户信息字段。
每一个用户字段指示一个RU或者一个组合的多RU,并将其分配给对应站点。
其中,如表14所示,用户字段可包括用户标识、空间流配置、调制编码策略、编码域等字段。此外,也可以将上述除用户标识外的其他字段移动至合并的用户域的最后一个字段中。该用户字段还包括新增的连续字段,以及,“RU个数或者RU分配位图”字段。其中,连续字段可由2比特构成,连续字段的取值0代表单个RU分配给该站点,这种情况下不存在“RU个数或者RU分配位图”字段;连续字段的取值1代表分配给该站点的是多个连续的RU,这种情况下“RU个数或者RU分配位图”字段的取值代表分配给站点的RU个数;连续字段的取值2代表分配给该站点的是多个不连续的RU,这种情况下,“RU个数或者RU分配位图”字段的取值代表未来X(例如X等于9)个RU的分配方式结果,如果未来X个RU中的某一个RU恰好也分配给了本站点,则对应比特置1,否则置0。如果分配位图字段的取值为0,则表示未来X个RU都未分配给本STA,可以直接跳至未来第X+1个RU对应的用户字段进行读取。
表14
Figure PCTCN2021070882-appb-000020
Figure PCTCN2021070882-appb-000021
例如,假设X等于9,连续字段的取值为2表示为站点分配的是多个非连续的RU,用户信息字段中第1个用户字段中的用户标识与该站点的用户标识相同,若RU分配位图字段的取值为010000000,则表示用户信息字段中第三个用户字段所对应的RU是分配给改站点的;若RU分配位图字段的取值为000000000,则表示用户信息字段中第二个至第十个用户字段所对应的RU均不是分配给该站点的,该站点需跳到第十一个用户字段,读取该第十一个用户字段中用户标识是否与自身的标识相同,若相同,可从该第十一个用户字段中读取其RU分配位图字段的取值,以确定第十二个用户字段至二十个用户字段所分别对应的RU是否为分配给该站点的RU,依次类推,直至解析完该用户信息字段。
可见,该资源分配方法能够在多用户传输中,实现接入点为用户分配多个资源单元。
上述本申请提供的实施例中,分别从接入点、站点的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能,接入点、站点可以包括硬件结构、软件模块,以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能可以以硬件结构、软件模块、或者硬件结构加软件模块的方式来执行。
