Description

一种多信道资源指示和确定方法、设备 技术领域
本发明涉及无线通信技术领域,特别涉及一种多信道资源指示和确定方法、设备。
背景技术
现有基于正交频分复用(英文:Orthogonal Frequency Division Multiplexing,简称:OFDM)技术的无线局域网(Wireless local Access Network,WLAN)标准,是由逐步演进的802.11a、802.11n、802.11ac等版本组成的。目前,IEEE(电气和电子工程师协会)802.11标准组织已经启动了高效率无线局域网(英文:High Efficiency WLAN,简称:HEW)的新一代WLAN标准802.11ax的标准化工作,并计划引入正交频分多址(英文:Orthogonal Frequency Division Multiple Access,简称:OFDMA)和上行多用户多入多出(英文:Uplink-Multi User-Multiple-Input and Multiple-Output,简称:UL-MU-MIMO)机制,从而提高了密集场景下单位面积的频谱使用效率。
现有WLAN***中,用户设备使用载波侦听多路访问/冲突避免(英文:Carrier sense multiple access with collision avoidance,简称:CSMA/CA)机制竞争信道的使用权利。如图1示出了现有802.11***的多信道资源使用方式。现有802.11***以20MHz作为资源分配的最小单位,并在信道上区分主信道(英文:primary channel)和从信道(英文:secondary channel)。信道的接入和使用都是在主信道上完成的。当用户设备希望使用信道时,就可以在主信道上发起信道使用侦听,在确认信道空闲分布式协调功能帧间隔(英文:DCF Interframe Space,简称:DIFS;英文:Distributed Coordination Function,简称:DCF)时间后启动退避过程。当退避计时器到达零点时,该用户设备就可以在主信道上进行数据的发送。如果用户设备希望使用比20MHz大的带宽时,则在主信道退避计时器到达零之前的点协调功能帧间隔(英文:PCF Interframe  Space,简称:PIFS;英文:Point coordination function,简称:PCF)时间监听从信道,这样,用户设备就可以捆绑(英文:bonded)主信道和从信道一起使用。这种方式可以有效地保证使用20MHz,40MHz,80MHz的用户设备共存,但是由于资源颗粒宽松(即用户设备必须在全频带上使用信道),资源使用效率低。
802.11ax***引入了OFDMA和UL-MU-MIMO机制后,用户设备可以工作在单信道(20MHz),也可以工作在多信道模式(40MHz,80MHz,160MHz)。目前,多信道模式下的资源指示如下:在使用OFDMA区分不同用户设备之前,接入点(英文:Access Point,简称:AP)传输OFDMA组(英文:group)信息元素(英文:Information Element,简称:IE)来指示每一个20MHz信道上用户设备。AP会在每一个20MHz信道上重复传输此OFDMA group IE让在每一个监听信道的用户设备都可以收到这个用户指示信息。在OFDMA分组正式开始之后,AP在各个子信道上传输信令字段(英文:Signaling,简称:SIG)会携带自身为每个用户设备所配置的资源的具***置。各个用户设备会根据SIG字段的信息找寻自己可以使用的资源的位置。
上述多信道资源指示方式是一种物理(简称:PHY)层和媒体接入控制(英文:Media Access Control,简称:MAC)层结合的资源指示方式。由于需要使用MAC层的IE指示信息,使得该资源指示方式灵活性差,反应速度慢,并且,使用MAC层IE指示信息会强制物理层在一定时间内使用固定的资源分配方式,使得每次更新资源指示方式都需要重新竞争信道发送IE指示信息,增加了信令开销。

具体实施方式
本发明实施例提供了一种纯PHY层的多信道资源指示方法,即网络设备 在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,以使用户设备能够确定自身在每个单信道上能够使用的资源块。由于本发明实施例提供的资源指示方法是纯物理层的指示方法,因此,资源配置灵活,反应速度快;另外,由于每帧的物理层帧头都可以携带上述指示信息,因此,本发明实施例提供的方法可以支持frame by frame的资源配置变更(即每帧都可以进行资源配置变更)。
本发明实施例中所述的单信道是指无线通信***中信道资源分配的基本单位。例如,针对使用5GHz频段的电气和电子工程学会(IEEE)802.11ax标准,其是以20MHz为基本单位进行信道资源分配的,则单信道即为使用的频带为20MHz的信道;又如,针对使用2.4GHz频段的标准,其是以5MHz为基本单位进行信道资源分配的则单信道即为使用的频带为5MHz的信道。
本发明实施例中所述的多信道是指包含至少两个单信道的信道。如使用的频带为40MHz的信道,其包含两个20MHz的单信道;又如,用的频带为80MHz的信道,其包含四个20MHz的单信道。
下面结合说明书附图对本发明实施例作进一步详细描述。应当理解,此处所描述的实施例仅用于说明和解释本发明,并不用于限定本发明。
本发明实施例可以应用于无线局域网,无线局域网可以为包含接入点的基本服务集(英文:Basic Service Set,简称:BSS)。应理解地,在无线保真(英文:Wireless Fidelity,简称:WiFi)***的基础网络结构下,网络中可以包括多个基本服务集,每个基本服务集可以包含一个AP和多个关联于该AP的STA。图2为一个典型的WLAN部署场景的***示意图,包括一个AP和一个STA,AP与STA之间通过多信道进行通信。
接入点(英文:Access Point,简称:AP),也称之为无线访问接入点或热点等。AP是移动用户进入有线网络的接入点,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。AP相当于一个连接有线网和无线网的桥梁,其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。目前AP主要采用的标准为电气 和电子工程师协会(英文:Institute of Electrical and Electronics Engineers,简称:IEEE)802.11系列。具体地,AP可以是带有WiFi芯片的终端设备或者网络设备。可选地,AP可以为支持802.11ax制式的设备,进一步可选地,该AP可以为支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种无线局域网(英文:Wireless Local Area Network,简称:WLAN)制式的设备。
站点(英文:Station,简称:STA),可以是无线通讯芯片、无线传感器或无线通信终端。例如: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通讯功能的机顶盒和支持WiFi通讯功能的计算机。可选地,站点可以支持802.11ax制式,进一步可选地,该站点支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。
当然,本发明实施例也可以应用于其他多载波通信***,如蜂窝通信网络。
如图3所示,本发明实施例提供了一种WLAN中网络设备侧的多信道资源指示方法,该方法包括:
S31、网络设备在用户设备能够使用的多信道所包含的每个单信道上,为所述用户设备配置资源块,并确定用于表示所述网络设备为所有用户设备在每个所述单信道上配置的资源块的指示信息;
S32、所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,其中,k个所述单信道的子帧的物理层帧头中包含全部单信道对应的所述指示信息,剩余n-k个所述单信道的子帧的物理层帧头中包含部分单信道对应的所述指示信息,n为大于或等于2的正整数,1≤k<n。
本发明实施例提供了一种多信道资源指示方法中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,由于该资源指示方法是纯物理层的指示方法,因此,资源配置灵活,反应速度快;另外,由于每帧的物理层帧头都可以携带上述指示信息,因此,本发明实施例提供的方法可以支持frame by frame的资 源配置变更。
在实施中,S31中,网络设备在用户设备能够使用的多信道所包含的每个单信道上为所述用户设备配置资源块时,可以将每个单信道上的频带资源按照预先设定的划分单元(如5MHz),将每个单信道上的频率资源划分为若干个资源块,并为用户设备在该单信道上配置能够使用的资源块。例如,用户1~用户3共享20MHz信道,在进行资源分配时,将该单信道划分为4个资源块,每个资源块5MHz,将该单信道的第一个资源块和第二资源块配置给用户1使用,将该单信道的第三个资源块配置给用户2使用,将该单信道的第四个资源块配置给用户3使用。其他单信道的资源分配方法类似,此处不再一一举例说明。
在实施中,网络设备根据***配置,可以允许每个用户设备使用单信道,也可以允许每个用户设备使用多信道。当网络设备只允许每个用户设备使用单信道时,则所有用户设备在该单信道上能够使用的资源块的指示信息都包含在该单信道的子帧的物理层帧头中,如图4所示,图中的信息块(英文:InfoBlock)中携带表示用户设备能够使用的资源块的指示信息。这样,每个用户设备通过接收解码子帧中的指示信息即可确定自己在该单信道上可以使用的资源块。
在实施中,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括如下两种优选的实现方式:
方式一、所述网络设备在第i个单信道的子帧的物理层帧头中,发送第i个单信道至第n个单信道对应的所述指示信息,其中,i=1,…,n,n为大于或等于2的正整数。
举例说明,假设网络设备允许用户设备1~用户设备3使用连续的40MHz的多信道,则该多信道包含的每个20MHz单信道均被等分为4个资源块,每个资源块5MHz。对于第一个单信道,用户设备1使用该单信道的前2个资源块,用户设备2使用该单信道的第3个资源块,用户设备3使用该单信道的 第4个资源块;对于第二个单信道,用户设备1使用该单信道的第1个资源块,用户设备2使用该单信道的第2个资源块,用户设备3使用该单信道的第3、4个资源块。此时,网络设备将用户设备1~用户设备3在第一个单信道和第二个单信道上能够使用的资源块的指示信息携带在第一个单信道的子帧的物理层帧头中,将用户设备1~用户设备3在第二个单信道上能够使用的资源块的指示信息携带在第二个单信道的子帧的物理层帧头中,如图5所示,图中Info Block中携带表示用户设备能够使用的资源块的指示信息。
又如,当网络设备允许用户设备使用连续的80MHz的多信道时,在该多信道所包含的第一个单信道上传输的子帧物理层帧头中携带该多信道所包含的每个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第二个单信道上传输的子帧的物理层帧头中携带除第一个单信道上每个用户设备能够使用的资源块的指示信息之外的其他单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第三个单信道上传输的子帧的物理层帧头中携带除第一个单信道和第二个单信道上每个用户设备能够使用的资源块的指示信息之外的其他单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第四个信道上传输的子帧的物理层帧头中仅携带第四个单信道上每个用户设备能够使用的资源块的指示信息,如图6所示,图中Info Block中携带表示用户设备能够使用的资源块的指示信息。
在实施中,所述多信道所包含的每个单信道中的每个资源块对应的指示信息可以采用如下方式表示:{Channel i,User j},含义为用户设备j在第i个单信道上能够使用的一个资源块的指示信息。
该方式下,对于所述多信道所包含的每个单信道的每个资源块均对应一个指示信息,用于表示能够使用该资源块的用户设备,在实施中,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括:
对于每个所述单信道,所述网络设备将需要在该单信道的子帧的物理层帧头中发送的所述多信道所包含的部分或全部单信道对应的所述指示信息, 按照资源块的编号顺序排列并发送。
具体的,对于所述多信道包含的每个单信道,该单信道的子帧的物理层帧头中携带的所有用户设备在该单信道上能够使用的资源块对应的指示信息,是按照该单信道的资源块的编号的顺序排列的。
举例说明,假设所述多信道包含的第i个单信道共有四个资源块,其中,网络设备为用户设备1分配第一个和第二资源块,为用户设备2分配第三个资源块,为用户设备3分配第四个资源块,则该单信道的子帧中携带的指示信息依次为:{Channel1,User1}、{Channel1,User1}、{Channel1,User2}、{Channel1,User3}。
该方式下,由于所述多信道包含的每个单信道上均携带有网络设备为所有用户设备在所述多信道所包含的部分或全部单信道上配置的资源块的指示信息,这样,即使用户设备在所述多信道所包含的某个单信道上接收指示信息失败,但该用户设备仍可以在所述多信道所包含的其他单信道上获取于表示网络设备为所有用户设备在所述多信道所包含的部分或全部信道上配置的资源块的指示信息,从而使该用户设备可以确定自身能够使用的资源块。
该方式下,为了提高信号接收的性能,降低误解码率,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括:
所述网络设备在每个所述单信道的子帧的物理层帧头中的同一位置,发送所述多信道所包含的部分或全部单信道对应的所述指示信息中相同的指示信息。
具体的,网络设备将所述多信道所包含的不同单信道的子帧的物理层帧头中所包含的相同的指示信息的起始位置,在不同单信道的子帧的物理层帧头中进行对齐处理,以使用户设备在接收到不同单信道的子帧的物理层帧头中携带的指示信息后,可以将不同单信道的子帧的物理层帧头所包含的相同的指示信息进行合并处理后再解码,从而提高信号接收的性能。
举例说明,如图7所示,从时间轴的起始位置开始,指示信息依次为 {Channel3,User6}、{Channel3,User5}、{Channel2,User4}、{Channel2,User3}、{Channel1,User2}和{Channel1,User1},其中,指示信息{Channel3,User6}和{Channel3,User5}表示所述多信道所包含的第三个单信道的第一个资源块被User6使用,且第三个单信道的第二个资源块被User5使用;指示信息{Channel2,User4}和{Channel2,User3}表示所述多信道所包含的第二个单信道的第一个资源块被User4使用,且第二个单信道的第二个资源块被User3使用;指示信息{Channel1,User2}和{Channel1,User1}表示所述多信道所包含的第一个单信道的第一个资源块被User2使用,且第一个单信道的第二个资源块被User1使用。由于三个单信道的子帧的物理层帧头中均包含第三个单信道上用户设备能够使用的资源块的指示信息,因此,网络设备可以将该指示信息的边缘对齐,这样,用户设备在接收到所述多信道所包含的不同单信道的子帧的物理层帧头中携带的指示信息后,可以将不同单信道的子帧的物理层帧头中所包含的相同的指示信息进行合并处理后再解码,从而提高了信号接收的性能。
方式二、所述网络设备在第i个单信道的子帧的物理层帧头中,发送第1个单信道至第i个单信道对应的所述指示信息,其中,i=1,…,n,n为大于或等于2的正整数。
举例说明,当网络设备允许用户设备使用连续的80MHz的多信道时,在该多信道所包含的第一个单信道上传输的子帧的物理层帧头中携带第一个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第二个单信道上传输的子帧的物理层帧头中携带第一个单信道和第二个单信道上每个用户设备能够使用的资源块的指示信息之外的其他单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第三个单信道上传输的子帧的物理层帧头中携带第一个单信道、第二个单信道和第三个单信道上每个用户设备能够使用的资源块的指示信息之外的其他单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第四个信道上传输的子帧的物理层帧头中携带第一个单信道、第二个单信道、第三个单信道和 第四个单信道上每个用户设备能够使用的资源块的指示信息。
该方式下,由于所述多信道所包含的每个单信道上均携带有网络设备为所有用户设备在所述多信道所包含的部分或全部单信道上配置的资源块的指示信息,这样,即使用户设备在所述多信道所包含的某个单信道上接收指示信息失败,但该用户设备仍可以在所述多信道所包含的其他单信道上获取于表示网络设备为所有用户设备在所述多信道所包含的部分或全部信道上配置的资源块的指示信息,从而使该用户设备可以确定自身能够使用的资源块。
在实施中,所述多信道所包含的每个单信道中的每个资源块对应的指示信息可以采用如下方式表示:{Channel i,User j},含义为用户设备j在所述多信道所包含的第i个单信道上能够使用的一个资源块的指示信息。
该方式下,对于所述多信道所包含的每个单信道的每个资源块均对应一个指示信息,用于表示能够使用该资源块的用户设备,在实施中,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括:
对于每个所述单信道,所述网络设备将需要在该单信道的子帧的物理层帧头中发送的所述多信道所包含的部分或全部单信道对应的所述指示信息,按照资源块的编号顺序排列并发送。
该方式下,为了提高信号接收的性能,降低误解码率,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括:
所述网络设备在每个所述单信道的子帧的物理层帧头中的同一位置,发送所述多信道所包含的部分或全部单信道对应的所述指示信息中相同的指示信息。
在实施中,网络设备可以采用上述任一方式,在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,具体采用哪种方式可以由网络设备确定并通知给用户设备,也可以由网络设备和用户设备协商确定,还可以预先设定,只要保证网络设备与用 户设备对指示信息的理解一致即可。当然,本发明实施例不限于采用上述方式在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,也可以采用其他方式。
当然,除了上述优选的实现方式,本发明实施例中所述网络设备还可以采用其他方式,在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息。具体如下:
1、所述网络设备在至少两个所述单信道的子帧的物理层帧头中发送所述多信道所包含的全部单信道对应的所述指示信息,且在剩余n-k个所述单信道的子帧的物理层帧头中发送所述多信道所包含的部分单信道对应的所述指示信息,其中,剩余n-k个所述单信道的子帧的物理层帧头中包含的指示信息部分相同或全部相同。
举例说明,仍以网络设备允许用户设备使用连续的80MHz的多信道为例,在该多信道所包含的第一个单信道上传输的子帧的物理层帧头中携带第四个单信道、第三个单信道、第二个单信道和第一个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第二个单信道上传输的子帧的物理层帧头中也携带第四个单信道、第三个单信道、第二个单信道和第一个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第三个单信道上传输的子帧的物理层帧头中携带第四个单信道和第三个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第四个信道上传输的子帧的物理层帧头中也携带第四个单信道和第三个单信道上每个用户设备能够使用的资源块的指示信息。
2、所述网络设备在一个所述单信道的子帧的物理层帧头中发送所述多信道所包含的全部单信道对应的所述指示信息,且在剩余n-k个所述单信道的子帧的物理层帧头中发送所述多信道所包含的部分单信道对应的所述指示信息,其中,剩余n-k个所述单信道的子帧的物理层帧头中包含的指示信息部分相同或全部相同。
举例说明,仍以网络设备允许用户设备使用连续的80MHz的多信道为例, 在该多信道所包含的第一个单信道上传输的子帧的物理层帧头中携带第四个单信道、第三个单信道、第二个单信道和第一个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第二个单信道上传输的子帧的物理层帧头中携带第四个单信道和第三个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第三个单信道上传输的子帧的物理层帧头中也携带第四个单信道和第三个单信道上每个用户设备能够使用的资源块的指示信息;在该多信道所包含的第四个信道上传输的子帧的物理层帧头中携带第四个单信道上每个用户设备能够使用的资源块的指示信息。
基于上述任一实施例,本发明实施例应用于不同的***中,子帧中能够携带表示用户设备能够使用的资源块的指示信息的字段也不同,作为一种优选的实现方式,若应用于OFDMA***中,S32中,所述网络设备在每个所述单信道的子帧的物理层帧头中,发送所述多信道所包含的部分或全部单信道对应的所述指示信息,包括:

S81、用户设备在自身能够使用的多信道所包含的每个单信道上,获取网络设备发送的子帧,所述子帧的物理层帧头中携带所述网络设备为所有用户设备在所述多信道所包含的部分或全部单信道上配置的资源块的指示信息, 其中,k个所述单信道的子帧的物理层帧头中包含全部单信道对应的所述指示信息,剩余n-k个所述单信道的子帧的物理层帧头中包含部分单信道对应的所述指示信息,n为大于或等于2的正整数,1≤k<n;
