Description

资源指示方法和装置 技术领域
本发明涉及通信领域,并且更具体地,涉及资源指示方法和装置。
背景技术
随着移动互联网的发展和智能终端的普及,数据流量呈现出爆发式的增长趋势。无线局域网(Wireless Local Area Network,WLAN)凭借其在高速率和低成本方面的优势,成为当今主流的移动宽带接入技术之一。
下一代WLAN系统802.11ax为了提升系统资源利用效率,可引入OFDMA技术,在同一时刻为不同的用户分配不同的信道资源,使多个用户高效地接入信道,提升信道利用率。对基于正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)的WLAN系统而言,接入点(Access Point,AP)可以在不同的时频资源上与不同的站点(Station,STA)进行上下行传输。在下行物理层协议数据单元(Physical Layer Protocol Data Unit,PPDU)中可以包含物理会聚协议(Physical Layer Convergence Procedure,PLCP)头域和数据域,PLCP头域可包括前导和控制域。其中控制域包括高效信令域A(High Efficient-Signaling A,HE-SIGA)和高效信令域B(High Efficient-Signaling B,HE-SIGB)部分。在HE-SIGB部分,包含AP对不同站点的上/下行(或下行)时频资源指示信息。站点通过接收并解码HE-SIGB信息,获知自身(上行和下行,或下行)传输的时频资源位置等资源指示信息,并在对应的时频位置上进行(上行和下行,或下行)传输。
同时,在接入点发送的触发帧(Trigger Frame)中,可以在PLCP头域的HE-SIGB控制域或MAC负载域(MAC payload)中,包含对不同站点的上行时频资源指示信息。站点通过接收并解码触发帧中的HE-SIGB信息或MAC负载域信息,获知自身上行传输的时频资源位置等资源指示信息,并在对应的时频位置上进行上行传输。
在密集部署场景下,多个站点的数据包特性不同,特别是某些站点希望接收或发送小包数据,如果小包用户与长包用户一起进行OFDMA传输,对每个小包的PPDU分别进行资源指示,存在PLCP包头开销浪费的问题,如 图1所示。

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的一部分实施例,而不是全部实施例。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的前提下所获得的所有其他实施例,都应属于本发明保护的范围。
本发明的技术方案,可以应用于各种无线通信系统,例如:基于无线保真(Wireless Fidelity,WIFI)、蓝牙(Bluetooth)、及全球微波互联接入(Worldwide Interoperability for Microwave Access,WiMAX)、无线局域网鉴别和保密基础结构(Wireless LAN Authentication and Privacy Infrastructure,WAPI)等等系统以及其它将终端以无线方式互相连接的通信系统。
接入点(AP,Access Point),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。
站点(STA,Station),可以是无线传感器、无线通信终端或移动终端,如支持WiFi通讯功能的移动电话(或称为“蜂窝”电话)和具有无线通信功能的计算机,例如,可以是支持WiFi通讯功能的便携式、袖珍式、手持式、计算机内置的或者车载的无线通信装置,它们与无线接入网交换语音和/或数据。
应理解,在本发明实施例中,术语“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系。例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
图2是本发明实施例可应用的WLAN部署场景示意图。如图2所示WLAN部署场景,包括一个AP和至少两个STA。示例性的,在图2所示的场景中,AP分别与STA1、STA2、STA3和STA4进行通信。可选的,AP可以为支持802.11ax制式的设备,并能够后向兼容802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。
图3是根据本发明实施例的一种资源指示方法300的示意性流程图。资源指示方法200可以由接入点执行。如图3所示,资源指示方法300包括如下内容。
310、确定m个时间段(Time Segment,TS)的资源指示信息,资源指示信息包括m个时间段与n个站点的对应关系,m为大于1的整数,n大于或等于m的整数。
例如,每个时间段对应至少一个站点。
应理解,m个时间段与n个站点的对应关系可以采用多种方式来实现,可以直接指示时间段与站点的对应关系,或者间接指示时间段与站点的对应关系,本发明实施例对此不做限定。
320、发送下行物理层协议数据单元PPDU,PPDU的物理会聚协议PLCP头域携带该资源指示信息,以便所述n个站点中的每个站点根据该资源指示信息在对应的时间段内收发数据;或者,
发送触发帧,触发帧的PLCP头域或媒体访问控制MAC负载域携带该资源指示信息,以便n个站点中的每个站点根据该资源指示信息指示的时频资源在对应的时间段内发送数据。
需要说明的是,AP发送下行PPDU时,在PPDU的PLCP头域携带站点的上行和下行、或下行传输的资源指示信息,相应地,站点接收下行PPDU,并根据PLCP头域携带的资源指示信息在对应的时间段接收下行数据,或者接收下行数据并发送上行数据;AP发送触发帧时,在触发帧的PLCP头域或MAC负载域携带站点的上行传输的资源指示信息,相应地,站点接收触发帧,并根据PLCP头域或MAC负载域携带的资源指示信息在对应的时间段发送上行数据。
本发明实施例中,发送PPDU时,PPDU的数据域会相应地划分成m段,每段携带发送给对应的站点的数据。
本发明实施例的资源指示方法,通过在一个下行PPDU的PLCD头域或者在一个触发帧的PLCD头域/MAC负载域携带多个时间段的资源指示信息,指示该多个时间段内的多个站点资源,能够高效地进行资源分配指示,进而能够节省资源指示开销。
另外,当某些站点希望接收或发送小包数据时,如果小包用户与长包用户一起进行OFDMA传输,则会存在数据包长度无法对齐的问题,如图4所示。
可选地,m个时间段中每个时间段对应的至少一个站点的PPDU的长度相同。这样就能够保证数据包的长度尽可能的对齐。
需要说明的是,m个时间段的长度可以不同。这样能够满足多种长度的数据包的对齐问题。
m个时间段的资源指示信息可以包括m个时间段的数量信息和m个时间段中每个时间段的长度信息。应理解,本发明实施例并不限于此,例如, 时间段的数量和每个时间段的长度可以是提前预设好的,此时,该资源指示信息中可以不包括时间段的数量信息和每个时间段的长度信息。
通过限制时间段的数量,能够避免出现长时间等待的站点,例如,时间段的个数为4或8个。例如,可以用2比特(bits)来指示时间段的数量。
其中,时间段的长度信息可以用正交频分多址OFDMA符号的个数或者OFDMA符号单位的个数表示。
若采用OFDMA符号的个数表示时间段的长度信息,则在5.4ms中最多可以传输5400/13.6=398个OFDMA符号,可用9bits来指示;若采用OFDMA符号单位的个数表示时间段的长度信息,则可以定义以下符号单位,包括8/16/32/64/128/256个符号单位,那么可用3bits信息来指示,如图6或图10所示。
PLCP头域包括高效信令域A HE-SIGA和高效信令域B HE-SIGB。
其中,HE-SIGB用于指示数据域的数据传输信息,HE-SIGA用于指示HE-SIGB的传输信息。
可选地,如图5所示,HE-SIGA携带m个时间段的数量信息,HE-SIGB携带m个时间段中每个时间段的长度信息。
由于HE-SIGA用于指示HE-SIGB的传输信息,换句话说HE-SIGA为HE-SIGB分配传输资源,本发明实施例中HE-SIGA携带m个时间段的数量信息,在每个时间段的长度为预设长度时,HE-SIGB根据HE-SIGA指示的时间段的数量能够直接确定循环冗余校验(Cyclic Redundancy Check,CRC)码的位置,从而准确地进行CRC。
应注意,m个时间段的数量信息也可以携带在HE-SIGB的部分,本发明实施例对此不做限定。
当PLCP头域中的HE-SIGB或MAC负载域携带m个时间段的资源指示信息时,可选地,m个时间段的资源指示信息还包括所述m个时间段中每个时间段对应的每个站点的资源配置信息,HE-SIGB或MAC负载域包括公共部分(common part)和用户部分(individual part)。
相应地,HE-SIGB或MAC负载域的公共部分携带每个时间段的长度信息,HE-SIGB或MAC负载域的用户部分携带以下至少一种信息:调制与编码策略(Modulation and Coding Scheme,MCS)、空间数据流数量(Number of Spatial Stream,NSS)和低密度奇偶校验码(Low density parity check code, LDPC)编码信息,如图8所示。
或者,HE-SIGB或MAC负载域的用户部分携带的每个站点的资源配置信息中包括该站点对应的时间段的长度信息,如图7所示。
可选地,HE-SIGB或MAC负载域的公共部分还可以携带m个时间段的数量信息,如图6所示。即HE-SIGB或MAC负载域的公共部分携带m个时间段的数量信息和m个时间段中每个时间段的长度信息。
需要说明的是,在公共部分携带时间段的长度信息只需以时间段为单位分别指示每个时间段的长度信息。而在用户部分需要在每个站点的资源配置信息中指示该站点所在的时间段的长度信息。当每个时间段对应多个站点时,在用户部分会出现重复指示一个时间段的长度信息的情况,因此在公共部分携带时间段的长度信息相对于在用户部分携带时间段的长度信息能够节省比特开销。
可选地,m个时间段的资源指示信息还可以包括m个时间段中每个时间段的频率配置信息。
例如,该每个时间段的频率配置信息包括每个时间段对应的每个站点的频率配置信息。
每个时间段的频率配置方式可以不同。以20MHz为例,若采用位图(Bitmap)的方式,则20MHz内可用9bits来表示每个时间段的频率配置方式。
相应地,HE-SIGB或MAC负载域的公共部分还携带m个时间段中每个时间段的频率配置信息(Frequency Resource Allocation,简称Freq RA),如图6或图8所示。
或者,HE-SIGB或MAC负载域的用户部分携带的每个站点的资源配置信息中包括该站点的频率配置信息,如图7所示。
也就是说,m个时间段中每个时间段的频率配置信息可以携带在公共部分,也可以携带在用户部分。
当HE-SIGB或MAC负载域的公共部分携带每个时间段的频率配置信息时,由于频率配置信息中包括站点和频率的对应关系,即间接包括了时间段和站点的对应关系。此时站点通过读取频率配置信息即可获知自身对应的时间段。
可选地,资源指示信息还可以包括m个时间段中的每个时间段对应的 站点的标识信息。例如,站点标识(Identifier,ID)。
相应地,HE-SIGB或MAC负载域的公共部分还携带m个时间段中的每个时间段对应的站点的标识信息,如图6所示。此时,站点可以根据公共部分携带的内容确定该站点对应的时间段。
或者,HE-SIGB或MAC负载域的用户部分携带的每个站点的资源配置信息中包括该站点标识信息,如图7或图8所示。此时,站点可以根据用户部分携带的内容确定该站点对应的时间段。
也就是说,每个时间段对应的站点的标识信息可以携带在公共部分,也可以携带在用户部分。
应注意,在多用户多入多出(Multi-User Multiple-Input Multiple-Output,MUMIMO)场景下,每个站点的资源配置信息中可以包括该站点所在的组的ID(Group ID)。
需要说明的是,HE-SIGB的公共部分还可以携带其他公共信息,如图9所示,本发明实施例对此并不限定,例如,还可以包括每个时间段的LTF模式。
在本发明实施例中,通过将HE-SIGB划分为公共部分和用户部分,在公共部分指示每个时间段的资源指示信息,如长度信息、频率配置信息和站点的标识信息等,能够节省比特开销。
可选地,HE-SIGB的公共部分携带的每个时间段的长度信息后面设置结束标识,如图10所示,该结束标识用于指示后续是否还有时间段的长度信息。例如,可以用1bit信息来指示结束标识。
从上面描述可知,公共部分携带的m个时间段中每个时间段的频率配置信息可以作为体现时间段与站点的对应关系的一种具体实现方式,公共部分携带的m个时间段中的每个时间段对应的站点的标识信息可以作为体现时间段与站点的对应关系的另一种具体实现方式。应理解,还可以携带能够指示时间段与站点的对应关系的其他信息,本发明实施例对此不做限定。
应理解,本发明实施例中HE-SIGB或MAC负载域也可以不划分为公共部分和用户部分,直接在HE-SIGB或MAC负载域中携带m个时间段的资源指示信息,本发明实施例对此并不限定。
图11为图6和图10中每个时间段的频率配置的例子。图12为图6和图10中每个时间段的站点标识的例子。
本发明实施例的资源指示方法,通过在一个下行PPDU的PLCD头域或者在一个触发帧的PLCD头域/MAC负载域携带多个时间段的资源指示信息,指示该多个时间段内的用户资源,能够高效地进行用户资源分配指示,进而能够节省资源指示开销。
图13是根据本发明另一实施例的资源指示方法1300的示意性流程图。资源指示方法1300对应于资源指示方法300,在此适当省略详细的描述。资源指示方法1300可以由站点执行。如图13所示,资源指示方法1300包括如下内容。

1330、在对应的时间段内收发数据或发送数据。
