Description

信息传输方法、用户设备及网络设备
本申请要求于2016年11月14日提交中国专利局、申请号为CN201611003694.X、申请名称为“信息传输方法、用户设备及网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术，尤其涉及一种信息传输方法、用户设备及网络设备。
背景技术
目前无线局域网(Wireless Local Area Networks，WLAN)大多工作在2.4GHz与5GHz频段，随着使用该频段的设备的增加，这一频段的频谱资源变得非常拥挤，而60GHz毫米波频段有着大量可用的频谱资源。因此60GHz频段将会在未来得到广泛的应用。
由于60GHz毫米波频段的路径损耗非常大，因而基于60Ghz毫米波频段的通信距离通常较短。为提高通信距离，可采用波束赋形(BeamForming，BF)的定向通信技术，可将发射天线的发射信号集中在一个很小的窄波束内，接收天线在一个很窄的波束范围内接收信号。在采用BF技术之前，网络设备可在信标间隔(Beacon Interval，BI)内的信标传输期间(Beacon Transmission Interval，BTI)内发送定向多千兆比特信标帧(Directional Multi-Gigabit，DMG Beacon Frame)，该DMG信标帧可包括BI内的关联波束赋形训练(Association BeamForming Training，A-BFT)的时长信息，接收到DMG信标帧的每个用户设备通过在该A-BFT期间，中随机选择的时隙(Timeslot)内向网络设备发送扇区扫描(Sector Sweep，SSW)帧，以实现用户设备的波束赋形训练。
随着通信技术的不断发展，用户设备个数在不断增多，这使得热点地区存在大量的用户，而一个BI内的A-BFT期间的时隙数目有限，这使得在A-BFT期间内，接收到信标帧的多个用户进行时隙竞争时，发生时隙冲突的概率较大，从而使得接入成功率较低。

本申请实施例一提供一种信息传输方法。图2为本申请实施例一提供的一种信息传输方法的流程图。如图2所示，该方法还可包括：
S201、网络设备根据待接入的用户设备个数和A-BFT时长，确定接入控制参数。
具体地，该待接入的用户设备个数可以为待接入的EDMG用户设备个数。该A-BFT时长可 以为一个BI内的A-BFT总时长，也可以为该一个BI内该EDMG用户设备的A-BFT时长。其中，该A-BFT时长可通过A-BTF的时长对应的时隙个数表示。
S202、网络设备向用户设备发送信标帧，该信标帧包括：该A-BFT的时长信息和该接入控制参数的指示信息。
具体地，网络设备例如可以是广播或组播的方式发送信标帧，以使得待接入的用户设备可接收到该信标帧。该网络设备可以是在BI内的BTI内向用户设备发送该信标帧。该信标帧例如可以为DMG信标帧。
S203、用户设备根据该A-BFT的时长信息确定该A-BFT的时间范围。
具体地，该用户设备可根据该A-BFT的时长信息确定该A-BFT的时长，继而预设的起始时间和该A-BFT的时长确定该A-BFT的时间范围。其中，该举例来说，若该A-BFT的时长为8，该预设起始时间为0，则该A-BFT的时间范围可以为时隙0至时隙7的八个时隙，可表示为[时隙0，时隙7]。
S204、用户设备根据该接入控制参数的指示信息确定该接入控制参数。
S205、用户设备根据该接入控制参数从该A-BFT的时间范围中选择时隙。
具体地，该用户设备可以是根据该接入控制参数确定该用户设备是否参与本次竞争接入，若是，则从该A-BFT的时间范围内随机选择一个时隙，继而在该选择的一个时隙内向网络设备发送SSW帧；若否，则该用户设备不参与本次竞争。
本申请实施例一提供的信息传输方法，可通过网络设备根据待接入的用户设备个数和A-BFT时长确定接入控制参数，并向用户设备发送包括该A-BFT的时长信息和该接入控制参数的指示信息的信标帧，使得接收到该信标帧的用户设备根据该A-BFT的时长信息确定该A-BFT的时间范围，根据该接入控制参数的指示信息确定该接入控制参数，并根据该接入控制参数从该A-BFT的时间范围中选择时隙，从而将同一A-BFT内竞争接入以进行波束赋形训练的用户设备的数量控制在一定范围内，降低A-BFT期间内用户设备间的发生时隙冲突的概率，提高接入成功率，提高波束赋形训练的效率，从而提高网络吞吐率。
在一种可实现方式中，如上所述的该接入控制参数可包括：第一接入阈值和第二接入阈值。该第一接入阈值，小于，该第二接入阈值。
若该接入控制参数包括该第一接入阈值和该第二接入阈值，则用户设备可以是根据该第一接入阈值的指示信息所在指示位对应的十进制数，确定该第一接入阈值；根据该第一接入阈值的指示信息所在指示位的比特数，确定该第二接入阈值。
其中，该第一接入阈值可表示为threshold，该第二接入阈值可以为最大接入阈值，可表示为MAX_Threshold。若该比特位数为N，则该MAX_Threshold的具体值例如可以为2N-1。举例来说，若该第一接入阈值的指示信息所在指示位为010，则可确定该第一接入阈值为2，由于N为3，则可确定该MAX_Threshold为7。也就是说，该第一接入阈值可以网络设备所设置的[0，MAX_Threshold]内的任一整数。
可选的，本申请实施例二还可提供一种信息传输方法。图3为本申请实施例二提供的一种信息传输方法的流程图。如图3所示，该方法在如上所述的S205中用户设备根据该接入控制参数从该A-BFT的时间范围中选择时隙可以包括：

S303、若该随机整数值小于或等于该第一接入阈值，则用户设备从该A-BFT的时间范围中随机选择一个时隙。
具体地，若该随机整数值小于或等于该第一接入阈值，则该用户设备可确定参与本次竞争。若该随机整数值大于该第一接入阈值，则该用户设备确定不参与本次竞争。
若该用户设备确定参与本次竞争，则该用户设备随机选择一个时隙，并启动该随机选择的一个时隙对应的定时器。若该定时器到时，则该用户设备可在该随机选择的一个时隙内向该网络设备发送该SSW帧。
如下结合下述表1进行实例说明。下述表1为本申请实施例二的信息传输方法中参与A-BFT时隙竞争对应的随机整数值与第一接入阈值的对应关系表。

表1
参照上述表1，若该第一接入阈值为000，也就是0，当用户设备生成的随机整数值为0的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为001，也就是1，当用户设备生成的随机整数值为0或1的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为010，也就是2，当用户设备生成的随机整数值为0、1或2的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为011，也就是3，当用户设备生成的随机整数值为0、1、2和3中任一的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为100，也就是4，当用户设备生成的随机整数值为0、1、2、3和4中任一的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为101，也就是5，当用户设备生成的随机整数值为0、1、2、3、4和5中任一的情况下，可确定参与A-BFT时隙竞争；若该第一接入阈值为110，也就是6，当用户设备生成的随机整数值为0、1、2、3、4、5和6中任一的情况下则可确定参与A-BFT时隙竞争；若该第一接入阈值为111，也就是7，当用户设备生成的随机整数值为0、1、2、3、4、5、6和7中任一的情况下则可确定参与A-BFT时隙竞争。
举例来说，若网络设备为PCP/AP，用户设备为站点，该站点可以为EDMG站点，该第二接入阈值为7，该第一接入阈值为4。图4为本申请实施例二提供的一种信息传输方法中一种PCP/AP与站点间的消息示意图。
如图4所示，PCP/AP在一个BI内的BTI内向各站点发送信标帧。站点1在接收到该信标帧后随机生成的整数值为2，小于该第一接入阈值4，因而，该站点1可从A-BFT时间范围内随机选择一个时隙7，并在该时隙7的定时器到来时向网络设备发送SSW帧，继而接收网络设备返回的SSW反馈(Feedback)帧。站点2在接收到该信标帧后随机生成的整数值为6，大于该第一接 入阈值4，因而，该站点2不参与本次A-BFT的时隙竞争。站点3在接收到该信标帧后随机生成的整数值为3，小于该第一接入阈值4，因而，该站点3可从A-BFT时间范围内随机选择一个时隙3，并在该时隙3的定时器到来时向网络设备发送SSW帧，继而接收网络设备返回的SSW反馈帧。
本申请实施例二提供的信息传输方法，在如上所述的方法的基础上，通过网络设备向用户设备发送包括第一接入阈值和第二接入阈值的信标帧，该第一接入阈值小于该第二接入阈值，使得产生的随机整数值小于或等于该第一接入阈值的用户设备可随机选择时隙继而竞争接入，使得产生的随机整数值大于该第一接入阈值的用户设备放弃竞争接入，可有效将同一A-BFT时间范围内竞争接入以进行波束赋形训练的用户设备的数量控制在一定范围内，降低A-BFT期间内用户设备间的发生时隙冲突的概率，提高接入成功率，提高波束赋形训练的效率，从而提高网络吞吐率。
在另一种方式中，如上所述的该接入控制参数可包括：接入概率。
该接入概率可以为该网络设备确定的小于或等于1的概率值。
若该接入控制参数包括该接入概率，则用户设备可以是根据该接入控制参数的指示信息所在指示位对应的十进制数，以及该指示位对应的最大值的比值，确定该接入概率。举例来说，若该接入控制参数的指示信息所在指示位为BNBN-1…B3B2B1，该接入控制参数的指示信息所在指示位对应的十进制数可以为
Figure PCTCN2017097798-appb-000002
该指示位对应的最大值可以为2N-1。则该用户设备可以是根据如下公式(1)得到该接入概率。

可选的，本申请实施例三还可提供一种信息传输方法。图5为本申请实施例三提供的一种信息传输方法的流程图。如图5所示，该方法在如上所述的S205中用户设备根据该接入控制参数从该A-BFT的时间范围中选择时隙可以包括：

举例来说，该用户设备可以是从[0，1]内生成一个随机值。
S502、用户设备比较该随机值和该接入概率。

具体地，若该随机值小于或等于该接入概率，则该用户设备可确定参与本次竞争。若该随机值大于该接入概率，则该用户设备确定不参与本次竞争。
若该用户设备确定参与本次竞争，则该用户设备随机选择一个时隙，并启动该随机选择的一个时隙对应的定时器。若该定时器到时，则该用户设备可在该随机选择的一个时隙内向该网络设备发送该SSW帧。
举例来说，若网络设备为PCP/AP，用户设备为站点，该站点可以为EDMG站点，该接入概率为0.3。图6为本申请实施例三提供的一种信息传输方法中一种PCP/AP与站点间的消息示意图。
如图6所示，PCP/AP在一个BI内的BTI内向各站点发送信标帧。站点1在接收到该信标帧后随机生成的随机数为0.747，大于该接入概率0.3，因而，该站点1不参与本次A-BFT的时隙竞争。站点2在接收到该信标帧后随机生成的随机数为0.231，小于该接入概率0.3，因而，该站点2可从A-BFT时间范围内随机选择一个时隙4，并在该时隙4的定时器到来时向网络设备发送SSW帧，继而接收网络设备返回的SSW反馈帧。站点3在接收到该信标帧后随机生成的随机数为0.357，大于该接入概率0.3，因而，该站点3不参与本次A-BFT的时隙竞争。

如下结合实例进行说明。图10为本申请实施例四提供的一种信息传输方法中一种PCP/AP与 站点间的消息示意图。
如图10所示，现有技术中，站点的竞争接入仅是针对主信道的，并且，在该主信道上，每个站点均可随机选择A-BFT时隙，继而发送SSW帧，其同一时隙内站点间发生时隙冲突的概率较大。图10中，若该站点B和站点D均在主信道上选择时隙0发送SSW帧，则站点B和站点D在时隙0处发生时隙冲突，使得站点B和站点D均接入失败；若仅该站点H在主信道上选择时隙1发送SSW帧，则站点H成功接入；若该站点I和站点J均在主信道上选择时隙2发送SSW帧，则站点I和站点J在时隙2处发生时隙冲突，使得站点I和站点J均接入失败；若仅该站点A在主信道上选择时隙3发送SSW帧，则站点A成功接入；若该站点E、站点C和站点G均在主信道上选择时隙4发送SSW帧，则该站点E、站点C和站点G在时隙4处发生时隙冲突，使得站点I和站点J均接入失败；若站点L和站点K均在主信道上选择时隙6发送SSW帧，则站点L和站点K在时隙6处发生时隙冲突，使得站点L和站点K均接入失败；若该站点F和站点M均在主信道上选择时隙7发送SSW帧，则站点F和站点M在时隙7处发生时隙冲突，使得站点F和站点M均接入失败。
如图10所示，基于本申请上述各实施例提供的单信道场景的方法，若该站点B和站点D均在主信道上选择时隙0发送SSW帧，则站点B和站点D在时隙0处发生时隙冲突，使得站点B和站点D均接入失败；若仅该站点H在主信道上选择时隙1发送SSW帧，则站点H成功接入；若仅站点I在主信道上选择时隙2发送SSW帧，则站点I在时隙2成功接入；若仅站点G在主信道上选择时隙4发送SSW帧，则站点G在时隙4成功接入；若站点L和站点K均在主信道上选择时隙6发送SSW帧，则站点L和站点K在时隙6处发生时隙冲突，使得站点L和站点K均接入失败；若仅该站点F在主信道上选择时隙7发送SSW帧，则站点F在时隙7成功接入。相比较现有技术，基于本申请上述各实施例提供的单信道场景的方法，在该主信道上，每个站点可根据如上所述的接入控制参数，如接入阈值或接入概率选择接入时隙，继而发送SSW帧，可有效减小了同一时隙内站点间发生时隙冲突的概率。
如图10所示，基于本申请上述各实施例提供的多信道场景的方法，若该站点B在主信道上选择时隙0发送SSW帧，站点D在从信道上选择时隙0接入，则站点B和站点D在时隙0处不会发生时隙冲突，使得站点B和站点D均接入成功；若仅该站点H在从信道上选择时隙1发送SSW帧，则站点H在从信道的时隙1成功接入；若仅站点I在主信道上选择时隙2发送SSW帧，则站点I在主信道的时隙2成功接入；若仅站点G在从信道上选择时隙4发送SSW帧，则站点G在从信道的时隙4成功接入；若站点L和站点K均在主信道上选择时隙6发送SSW帧，则站点L和站点K在主信道的时隙6处发生时隙冲突，使得站点L和站点K均接入失败；若仅该站点F在主信道上选择时隙7发送SSW帧，则站点F在主信道的时隙7成功接入。相比较现有技术以及本申请上述各实施例提供的单信道场景的方法，该多场景下的信息传输方法，可使得主信道和从信道上均每个站点均可根据如上所述的接入控制参数如接入阈值或接入概率选择接入时隙继而发送SSW帧，更有效地减小了同一时隙内站点间在同一信道的同一时隙内发送接入冲突的概率。
图11为本申请实施例四提供的一种待接入用户设备数与成功接入的用户设备数的对应图。如图11所示，现有技术中当用户设备数大于预设值时，随用户设备数的增加，由于时隙冲突的增加，使得现有技术中成功接入的用户设备数逐渐下降。而采用本申请上述各实施例提供的单信道场景的信息传输方法，由于用户设备可基于网络设备灵活配置的接入控制参数进行时隙竞争，使得用户设备数大于预设值时，随用户设备数的增加，成功接入的用户设备数还可保持在较高的水平， 其有效提高了用户设备的接入效率，提高了波束赋形训练的成功率。
图12为本申请实施例四提供的另一种待接入用户设备数与成功接入的用户设备数的对应图。如图12所示，现有技术中当用户设备数大于预设值时，随用户设备数的增加，由于时隙冲突的增加，使得现有技术中成功接入的用户设备数逐渐下降。而采用本申请实施例四提供的多信道场景的信息传输方法，由于用户设备可基于网络设备灵活配置的接入控制参数进行时隙竞争，并且可通过多信道接入，减小了用户设备在同一信道上的同一时隙内的接入冲突，使得用户设备数大于预设值时，随用户设备数的增加，成功接入的用户设备数还可保持在较高的水平，并且，该成功接入的用户设备数相比较单信道场景的信息传输，其还有明显的提高，有效提高了用户设备的接入效率，提高了波束赋形训练的成功率。
本申请实施例四提供的该信息传输方法，可通过在多个信道上采用上述任一实施例所述的方法，更有效地减小同一时隙内站点间在同一信道的同一时隙内发送接入冲突的概率。
可选的，如上所述的A-BFT的时长信息包括：主信道对应的DMG时长信息、主信道对应的EDMG时长信息；该主信道对应的DMG时长信息用于使得DMG用户设备确定DMG时间范围，从该DMG时间范围内随机选择一个时隙，继而在该随机选择的时隙内向该网络设备发送SSW帧。
举例来说，图13为本申请实施例四提供的一种BI控制域的结构示意图。如图13所示，BI控制域可包括：一个比特(bit)的当前簇控制(Clustering Control Present)字段、一个比特的发现节点(Discovery Mode)字段、4个比特的下一信标帧(Next Beacon)字段、一个比特的当前ATI(ATI Present)字段、3个比特的A-BFT长度字段、4个比特的扇区扫描帧(Frame of Sector Sweep，FSS)字段、1个比特的是否应答方发送扇区扫描(Is Responder Transmit Sector Sweep，Is Responder TXSS)字段、4个比特的下一A-BFT字段、一个比特的分散发送扇区扫描(Fragmented TXSS)字段、7个比特的发送扇区扫描范围(TXSS Span)、4个比特的N BIs A-BFT字段、6个比特的A-BFT计数(A-BFT Count)字段、6个比特的天线接口的第N个A-BFT(N A-BFT in Ant)、一个比特的基本服务集控制点关联准备(Personal Basic Service Set Control Point Association Ready，PCP Association Ready)字段及4个比特的预留(Reserved)字段。
主信道对应的DMG时长信息例如可位于该图13中的A-BFT长度字段，即比特7(Bit7，B7)至比特9(Bit9，B9)。主信道对应的EDMG时长信息例如可以位于该图13所述的BI控制域中的该A-BFT长度字段外的预留字段，即比特45(Bit45，B45)至比特(Bit47，B47)中至少一个比特位。主信道对应的EDMG时长信息还可以位于该图13所述的BI控制域中的该A-BFT长度字段外的其他字段的至少一个比特位。
EDMG用户设备可根据A-BFT长度字段的值加一，确定该EDMG时间单位的起始时间。
可选的，如上所述的S902中用户设备根据该一个可用信道对应的时长信息确定该一个可用信道对应的时间范围，可以包括：
若该一个可用信道为主信道，用户设备可根据该主信道对应的EDMG时长信息确定该一个可用信道对应的时间范围。
可选的，如上所述的信标帧还包括：从主信道对应的EDMG时长信息；
可选的，如上所述的S902中用户设备根据该一个可用信道对应的时长信息确定该一个可用信道对应的时间范围，可以包括：
若该一个可用信道为从信道，用户设备根据该从信道对应的EDMG时长信息确定该一个可用信道对应的时间范围。
可选的，如上所述的方法中，该主信道对应的DMG时长和该主信道对应的EDMG时长为该网络设备根据待接入的DMG用户设备的个数、待接入的EDMG用户设备的个数和该待接入的EDMG用户设备的可用信道的个数确定的。
具体地，若该待接入的DMG用户设备的个数为N1，该待接入的EDMG用户设备的个数为N2，那么，一个BI内的A-BFT时间范围内可接入的EDMG用户设备个数为N2*P，DMG用户设备的个数为N1。该信息传输方法中可根据N2*P与N1，在保证可接入的DMG用户设备的个数和EDMG用户设备的个数相等或相近的情况下，将一个BI内的A-BFT时间范围分成两部分。其中，一部分为DMG时间范围，另一部分为EDMG时间范围，实现主信道上对应的A-BFT时隙分离，对于次信道上A-BFT时间范围的所有时隙可以均为EDMG时间范围。
举例来说，若一个基本服务集(Basic Service Set，BSS)中，待接入的EDMG用户设备个数为20，待接入的DMG用户设备个数为4，一个BI内的A-BFT的时长为8即包括8个时隙。其中，EDMG用户设备具有两个可用信道，包括主信道和一个从信道；DMG用户设备仅具有一个可用信道，即主信道。若为了使得能够接入的用户设备个数尽可能多，可使网络设备下发的EDMG用户设备的接入概率P＝1/2。为保证EDMG用户设备和DMG用户设备的接入公平性，可对A-BFT时间范围进行如下图14所示的划分。图14为本申请实施例四提供的一种DMG用户设备和EDMG用户设备对应的时隙结构图。如图14所示，该信息信息传输方法中，可将主信道的A-BFT时间范围中的时隙0-时隙3配置为DMG时间范围，将主信道的A-BFT时间范围中的时隙4-至时隙7和从信道上的A-BFT时间范围的所有时隙均配置为EDMG时间范围。
本申请实施例四提供的该信息传输方法，还可通过控制该主信道对应的DMG时长和该主信道对应的EDMG时长，保证DMG用户设备和EDMG用户设备间的接入公平性。
