Description

干扰消除方法、设备和计算机可读存储介质 技术领域
本申请实施例涉及通信技术，尤其涉及一种干扰消除方法、设备和计算机可读存储介质。
背景技术
非授权频谱指的是公共频谱，任何组织或者个人都可以使用，也就是各种设备可以自由的在非授权频段上通信。目前，在3GPP讨论的新频段52GHz至71GHz频段中，存在非授权频谱，因此存在NR(New Radio，新空口)与WiFi共存的场景，会有信号冲突、碰撞、干扰的情况。
一些实现中，NR与WiFi仍没有共通的信令可以相互交互协调资源，同时带宽宽度、时间单位等资源配置也不一定相同，因此同在非授权频段通信容易彼此干扰。另外，还存在隐藏节点(hidden node problem)的情况，特别是在52GHz至71GHz的高频段，由于系统发射的电磁波都是功率非常集中的窄波束，因此发送端(或接收端)并不一定完全知道接收端(或发送端)现有干扰情况，没有明确的回退机制，干扰可能因此不能被系统探测到，从而发生通信干扰加剧的情况。例如，发送端侦测到现有资源是闲置状态并发送指示信息尝试与接收端建立连线，此时接收端正处于其他设备干扰阶段无法正常接收传送端的任何信息，导致传送端周期性、非周期性的发送连线建立信息此时造成功耗以及形成不必要的干扰信号；或者，发送端知道有干扰的情况，但接收端不知道发送端有干扰仍持续监听资源，或是尝试发送连线建立信息，造成功耗以及形成不必要的干扰信号。
前面的叙述在于提供一般的背景信息，并不一定构成现有技术。

本申请实施例具体的应用场景如下：目前对于52GHz至71GHz的非授权频段，各种设备可以自由的在非授权频段上通信，因此会有信号冲突、碰撞、干扰的情况，同时考虑到WiFi 802.11ad已经有相关标准运作在相同非授权频段上LBT(Listen before talk，先听后说)的通信方式，因此也需要考虑NR与WiFi共存的场景。本实施例以71GHz高频非授权频段为例进行示例性地说明。
一种可能方案：采用WiFi 802.11ad LBT的方式，例如DCF(Distributed Coordination Function，分散式协调功能)；进一步地可以采用方向性(directional)LBT的通信方式，因为高频信号容易衰减、通信距离较短，因此必须透过波束赋形(Beamforming)的方式来补足其先天缺陷。综上，也就是在具有方向性的通信基础上实施LBT。
另外，还可以考虑隐藏节点(hidden node problem)，也就是发送端不一定知道接收端现有状况，接收端有可能正处于干扰阶段，可以采用基于接收端辅助(Receiver assisted/based)的LBT。
另一种可能的方案：采用WiFi DCF。本方案中RTS(Request to send，要求发送)为发送端用来与接收端建立连线请求的信号，CTS(Clear to send，可以发送)为接收端用来反馈发送端建立连线请求的信号，也就是接收端在接收到发送端发送的RTS后的反馈信息。本方案具体流程如下：
步骤1、发送端在即将发送的资源上监听(Listen)DIFS(Distributed Inter-frame Spacing，分布式帧间间隙)时长，在确认该资源空闲后发送RTS信息。
步骤2、接收端在接收到RTS信息后，在该资源上监听(Listen)SIFS(Short Interframe Space，短帧间间隔)时长，在确认该资源空闲后发送CTS信息。
步骤3、当发送端接收到反馈的CTS信息后即可开始与接收端进行数据传输。
步骤4、若发生例外情况，发送端需要再重新发送RTS信息。
其中，例外情况包括：接收端没能正常接收到RTS信息，因此无法反馈CTS信息；接收端反馈的CTS信息无法被发送端正常接收。
由于NR与WiFi目前仍没有共通的信令可以相互交互协调资源，同时资源配置(例如带宽宽度、时间单位等)也不一定相同，因此NR与WiFi同在非授权频段通信容易彼此干扰。
一种可能的场景中，考虑到存在隐藏节点(hidden node problem)的情况： 发送端并不一定完全知道接收端现有干扰情况，没有明确的回退机制，干扰可能因此加剧。
具体地，发送端侦测到现有资源是闲置状态，并发送指示信息尝试与接收端建立连线，此时接收端正处于其他设备干扰阶段，无法正常接收传送端的任何信息，导致传送端周期性或者非周期性的发送连线建立信息，此时造成发送端功耗以及形成不必要的干扰信号。
例如，如图2和图3所示的NR与WiFi彼此干扰的场景中，WiFi AP(access point，接入点)为WiFi设备，TRP#1以及TRP#2为基站的两个TRP(Transmission Reception Point，传输接收点)，UE beam#1和UE beam#1分别为终端(UE#1)与TRP#1和TRP#2连线的波束。
如图2所示，终端(UE#1)接收到WiFi AP发射的波束指向WiFi UE的RTS信号，终端判断有干扰源：终端(UE#1)与基站的TRP#1以及TRP#2建立连线，此时终端在与TRP#1连线的波束(UE beam#1)上接收到WiFi AP发送的RTS信号，终端获知在这个方向的资源(如图2中斜线填充部分的UE beam#1)将被使用，将无法正常与TRP#1通信，而此时TRP#1不知道在这个方向上的资源(UE beam#1)将被使用，因为WiFi UE发回的CTS消息由于覆盖范围的限制没有被TRP#1接收到。
如图3所示，WiFi AP发起的RTS信号方向指向WiFi UE，基站(TRP#1)判断受到干扰：终端与基站(TRP#1以及TRP#2)建立连线，此时基站在TRP#1上的波束上接收到WiFi AP发送的RTS信号，基站获知在这个方向的资源(如图3中斜线填充部分的基站在TRP#1上的波束)将被使用，将无法正常与终端通信，而此时终端不知道在这个方向上的资源将被使用，因为WiFi AP发送的RTS消息由于覆盖范围的限制没有被终端接收到。
本申请提供的干扰消除方法，旨在基于上述场景，当第一通信设备与第二通信设备之间通过多个波束连接时，若第一通信设备确定第一连接波束上存在干扰，则通过不存在干扰的第二连接波束发送干扰指示信息，干扰指示信息用于指示第一连接波束存在干扰，也即通过不存在干扰的第二连接波束通知第二通信设备，使得第二通信设备可以获知当前第一连接波束上存在干扰，暂停使用第一连接波束进行通信，可以避免出现因为不同系统覆盖范围的限制导致RTS或CTS没有被接收端接收的情况，从而可以避免造成第二通信设备的功耗及形成不必要的干 扰信号，达到消除干扰信号的目的。
下面以具体地实施例对本申请实施例的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请实施例的实施例进行描述。
图4为本申请实施例一提供的一种干扰消除方法流程图。如图4所示，该方法具体步骤如下：
步骤S401、第一通信设备若确定第一连接波束上存在干扰，则通过不存在干扰的第二连接波束发送干扰指示信息，干扰指示信息用于指示第一连接波束存在干扰。
本实施例中，第一通信设备与第二通信设备之间通过多个波束连接。
其中，第一通信设备可以是终端设备也可以是网络设备，可以作为发送端也可以作为接收端。第一通信设备和第二通信设备进行通信时，第一通信设备可以作为发送端或者接收端，第二通信设备也可以作为发送端或者接收端。当第一通信设备作为发送端时，第二通信设备为接收端，当第一通信设备作为接收端时，第二通信设备为发送端。另外，第一通信设备可以为终端设备或者网络设备，第一通信设备为终端设备时，第二通信设备为网络设备，第一通信设备为网络设备时，第二通信设备为终端设备。
本实施例中，第一通信设备与第二通信设备通信过程中，若确定第一连接波束上存在干扰，那么第二通信设备通过不存在干扰的第二连接波束发送干扰指示信息，已通知第二通信设备当前第一连接波束存在干扰的情况。
步骤S402、第二通信设备通过第二连接波束接收干扰指示信息，干扰指示信息用于指示第一连接波束存在干扰。
在与第一通信设备通信过程中，第二通信设备通过第二连接波束接收用于指示第一连接波束存在干扰的干扰指示信息，可以获知第一连接波束存在干扰的情况。
步骤S403、第二通信设备根据干扰指示信息，暂停使用第一连接波束进行通信。
在接收到干扰指示信息之后，第二通信设备可以确定当前第一连接波束存在干扰，暂停使用第一连接波束进行通信，从而可以避免功耗及继续通过第一连接 波束发送或监听数据造成不必要的干扰。
本实施例中，若第一通信设备为发送端，发送端在其中一套连接资源(第一连接波束)上发生其他设备干扰下，通过另一套连接资源(第二连接波束)通知接收端(第二通信设备)暂停在该受干扰的资源上通信(监听)；若第一通信设备为接收端，接收端在其中一套连接资源(第一连接波束)上发生其他备干扰下，透过另一套连接资源(第二连接波束)通知发送端暂停在该受干扰的资源上通信(发送)；从而在第一通信设备与第二通信设备之间存在多套连接资源(多个方向上的连接资源且可以互补)的场景下，增加回退机制，避免干扰。
本申请实施例通过第一通信设备在确定第一连接波束上存在干扰时，则通过不存在干扰的第二连接波束发送用于指示第一连接波束存在干扰的干扰指示信息，第二通信设备通过第二连接波束接收干扰指示信息，可以及时地获知第一连接波束存在干扰的情况，并根据干扰指示信息，暂停使用第一连接波束进行通信，从而可以避免造成第二通信设备不必要的功耗及形成不必要的干扰信号，达到消除干扰的效果。
在高频71GHz频段，有部分频段与802.11ad重合，所以信道接入问题是一个在高频系统中首先要解决的一个问题。RTS/CTS作为一种已经在802.11ad中使用的技术，引起了广泛的注意。在新的高频场景，基于RTS/CTS的信道接入方法需要重新考虑设计。图5提供了在高频基于波束的系统中一个典型的多TRP连接场景，如图5所示的场景中，NR基站通过多TRP(如图5中所示的TRP/panel 1和TRP/panel 2)与NR UE(如图5中所示的NR UE 1)连接，此时NR UE 1可形成两个接收波束分别接收来自TRP/panel 1和TRP/panel 2的信号。此时在TRP/panel 1和NR UE 1中间有一个WIFI的隐藏节点WIFI AP，此时WIFI AP向WIFI UE 2发送RTS，NR UE 1因为接收波束同向，因此可以接收到该RTS，从而可保持静默，暂时不再与基站通信，WIFI UE 2此时接收到WIFI AP发送的RTS后，会回CTS消息给WIFI AP，但此时由于覆盖范围的限制，CTS可能并不会被NR基站接收到，所以此时TRP/panel 1可能会继续在该波束上向NR UE 1发送消息，进而导致对WIFI通信的干扰。
图6提供了在高频基于波束的系统中另一个典型的多TRP连接场景，如图6所示的场景中，NR基站通过多TRP(如图6中所示的TRP/panel 1和TRP/panel 2)与NR UE(如图6中所示的NR UE 1)连接，此时NR UE 1可形成两个接收波 束分别接收来自TRP/panel 1和TRP/panel 2的信号。此时在TRP/panel 1远离NR UE 1一侧有一个WIFI的隐藏节点WIFI AP，TRP/panel 1在WIFI AP与WIFI UE2中间，此时WIFI AP向WIFI UE 2发送RTS，由于覆盖范围的限制，NR UE 1无法接收到WIFI AP的RTS；WIFI UE 2接收到RTS后向WIFI AP发送CTS，TRP/panel 1因为接收波束同向，因此可以接收到该CTS，也即是TRP/panel 1可收到WIFI UE 2的CTS，但NR UE 1无法收到WIFI AP的RTS，所以此时NR UE 1可能会继续在该波束上向TRP/panel 1发送消息，进而导致对WIFI通信的干扰。
图7为本申请实施例二提供的一种干扰消除方法流程图。在上述实施例一的基础上，本实施例中，基于图5或者图6所示的应用场景，对本实施例提供的干扰消除方法的具体实现方式进行示例性地说明。如图7所示，该方法具体步骤如下：
步骤S501、第一通信设备若在第一连接波束上检测到信道被占用信息，则确定第一连接波束上存在干扰。
本实施例中，第一通信设备与第二通信设备之间通过多个波束连接。具体可以应用于高频非授权频段多波束连接场景下，其中多波束可以通过多个TRP或者单个TRP实现，本实施例此处不做具体限定。
其中，第一连接波束用于指代存在干扰的连接波束，第二连接波束用于指代不存在干扰的连接波束。在不同时刻，各个连接波束上是否存在干扰的情况可能会发生变化，第一连接波束和第二连接波束所包含的连接波束也可能会发生变化。
存在干扰的第一连接波束可以有一个或者多个，若当前有多个存在干扰的第一连接波束，第一通信设备可以选择通过其他不存在干扰的第二连接波束发送干扰指示信息。
其中，信道被占用信息包括以下至少一项：连线请求信号，连线反馈信号。
可选地，连线请求信号为RTS，连线反馈信号为CTS。信道被占用信息还可以包括特定符合等其他信息，本实施例此处不做具体限定。
示例性地，在第一连接波束上检测到信道被占用信息，可以是在第一连接波束上接收到WiFi AP发送的RTS信号、或CTS信号、或特定符号；或者是在第一连接波束上检测到的信号强度高于阈值。
其中，特定符号和阈值可以根据实际应用场景进行配置和调整，本实施例此处不做具体限定。
步骤S502、若确定第一连接波束上存在干扰，第一通信设备暂停使用第一连接波束进行通信。
该步骤在确定第一连接波束上存在干扰时执行，可以在步骤S503之前，或者在步骤S503之后，本实施例此处不做具体限定。
当第一通信设备确定第一连接波束上存在干扰时，为避免造成不必要的功耗和干扰，暂停使用第一连接波束进行通信。
该步骤中，第一通信设备暂停使用第一连接波束进行通信，包括：暂停通过第一连接波束发送数据；和/或，暂停对第一连接波束的监听。
当第一通信设备确定第一连接波束上空闲时，恢复使用第一连接波束进行通信。
步骤S503、第一通信设备通过不存在干扰的第二连接波束发送干扰指示信息，干扰指示信息用于指示第一连接波束存在干扰。
可选地，第一通信设备可以通过下行控制信息或上行控制信息发送干扰指示信息。
例如，可以在DCI(Downlink Control Information，下行控制信息)或者UCI(Uplink Control Information，上行控制信息)中设置控制字段，通过此控制字段在其他不存在干扰的第二连接波束发送干扰指示信息。
步骤S504、第二通信设备通过第二连接波束接收干扰指示信息，干扰指示信息用于指示第一连接波束存在干扰。
可选地，第二通信设备通过第二连接波束接收干扰指示信息，包括：
第二通信设备通过第二连接波束接收包含干扰指示信息的下行控制信息；或者，第二通信设备通过第二连接波束接收包含干扰指示信息的上行控制信息。
步骤S505、第二通信设备根据干扰指示信息，暂停使用第一连接波束进行通信。
在一种可能的实施方式中，干扰指示信息包括第一连接波束的索引信息和/或第一连接波束的保持静默时间。其中，保持静默时间为：若第一连接波束存在干扰，需要暂时停止使用第一连接波束进行通信的时间，第一连接波束的索引信息用来指示是哪个波束上存在干扰。
第一通信设备在第一连接波束的保持静默时间结束、或接收到恢复通信指示时，确定第一连接波束空闲，恢复使用第一连接波束进行通信。
其中，恢复通信指示用于指示第一连接波束上的原有干扰通信结束。例如，恢复通信指示可以是向第一通信设备发送的可以恢复第一连接波束的数据传输的信令，表示第一连接波束上的原有干扰通信结束，具体由谁向其发送指示或者恢复通信指示包含哪些具体信息，本实施例此处不做具体限定。
该步骤中，第二通信设备根据干扰指示信息，暂时停止使用索引信息对应的第一连接波束进行通信，直至保持静默时间结束。第二通信设备在第一连接波束的保持静默时间结束时，恢复使用第一连接波束进行通信。
在另一种可能的实施方式中，干扰指示信息包括第一连接波束的索引信息和/或第一连接波束的停止传输标识。停止传输标识用于指示停止使用第一连接波束进行通信。
具体地，第二通信设备根据停止传输标识，停止使用索引信息对应的第一连接波束进行通信；也就是第二通信设备在接收到包含停止传输标识的干扰指示信息时，停止使用干扰指示信息中的索引信息对应的第一连接波束进行通信。
第一通信设备在第一连接波束的保持静默时间结束、或接收到恢复通信指示时，确定第一连接波束空闲，恢复使用第一连接波束进行通信。
进一步地，第一通信设备若确定第一连接波束空闲，则通过第一连接波束或者第二连接波束发送恢复指示信息。恢复指示信息包括第一连接波束的索引信息和/或第一连接波束的恢复传输标识。恢复传输标识用于指示恢复使用第一连接波束进行通信。
第二通信设备通过第一连接波束或者第二连接波束接收恢复指示信息。第二通信设备根据恢复传输标识，恢复使用第一连接波束进行通信。也就是，第二通信设备在接收到包含恢复传输标识的恢复指示信息时，恢复使用恢复指示信息中索引信息对应的第一连接波束进行通信。
该步骤中，第二通信设备根据干扰指示信息，暂停使用第一连接波束进行通信，包括：根据干扰指示信息，暂停通过第一连接波束发送数据；或者，根据干扰指示信息，暂停对第一连接波束的监听。
示例性地，若第二通信设备作为发送端，则根据干扰指示信息，暂停通过第一连接波束发送数据。若第二通信设备作为接收端，则根据干扰指示信息，暂停对第一连接波束的监听。
可选地，可以使用一个比特来存储停止传输标识或者恢复传输标识，例如， 用“0”表示停止传输标识，“1”表示恢复传输标识。
步骤S506、第一通信设备在第一连接波束的保持静默时间结束、或接收到恢复通信指示时，确定第一连接波束空闲，恢复使用第一连接波束进行通信。
步骤S507、第二通信设备在第一连接波束的保持静默时间结束、或接收到包含恢复传输标识的恢复指示信息时，恢复使用第一连接波束进行通信。
示例性地，基于图5或图6所示的场景，为了解决如图5或图6所示场景存在的问技术问题，在高频非授权频段多波束连接场景下，基站或终端当前有多个波束连接。当其中一个或多个波束(非全部连接波束)上检测到RTS或CTS后，在其他没有收到RTS或CTS的一个或多个波束上的对应上行或下行控制信息中，发送包含对应RTS或CTS上的保持静默时间和波束索引信息的消息，基站或终端收到此消息字段后，就知道需要在哪个波束上保持静默(不发送任何信号)；或者，在其他没有收到RTS或CTS的一个或多个波束上的对应上行或下行控制信息中，发送指示信息和对应RTS或CTS的波束索引信息，其中指示信息包括停止传输标识或者恢复传输标识，基站或终端收到此指示信息和波束索引信息后，就知道需要在哪个波束上停止或恢复数据传输。
例如，RTS字段可以如下：
1.Frame Control
2.Duration
3.RA(Receiver Address，接收端地址)
4.TA(Transmitter Address，发送端地址)
5.FCS(Frame Check Sequence，帧检验序列)
CTS字段可以如下：
1.Frame Control
2.Duration
3.RA
4.FCS
其中，Frame Control(帧控制)表征传输的数据来自控制帧还是管理帧。Duration指示了接收端需要等待保持静默的时间。终端或基站在接收到RTS/CTS时，将此段信息(Duration)连同对应的TRP或者波束索引(TRP/beam Index)通过UCI或者DCI在其他没有干扰的波束上发送给接收端，这样接收端可知道 信息需要保存静默的时间，避免出现因为覆盖范围限制导致RTS或CTS没有被接收端接收的情况。
那么，如图5中所示，在TRP/panel 1上有波束连接至NR UE 1，此时有干扰WIFI AP，在NR UE 1收到WIFI AP发送的RTS后，随即将RTS中的Duration和波束索引(TRP/beam Index)信息组成字段【duration TRP/beam 1】，并通过UCI发至TRP/panel 2。此时基站可以知道TRP/beam 1有干扰，也知道需要保持静默的时间Duration，即使此情况下由于覆盖范围NR UE 2发送的CTS没有被TRP/panel 1接收到。
例如，可以使用一个比特来存储停止传输标识或者恢复传输标识，例如，用“0”表示停止传输标识，“1”表示恢复传输标识。
那么，如图5中所示，在TRP/panel 1上有波束连接至NR UE 1，此时有干扰WIFI AP，在NR UE 1收到WIFI AP发送的RTS后，使用干扰指示信息发送字段【0，TRP/beam#1】告诉基站暂时停止在TRP#1上通信，待NR UE 1判断TRP#1空闲时发送字段【1，TRP/beam#1】告诉基站可以在此TRP上恢复通信，NR UE 1判断信道空闲的方法包含但不限于以下方式：根据自身收到的RTS/CTS中的“Duration”判断静默时间已过、或者根据收到的可以恢复数据传输的信令。
示例性地，第一通信设备可以在多波束连接情况下，内部可保存一个向量，保存对应连接波束的有无干扰情况以及相应的需要保持静默的时间。
例如，如图5中所示的NR UE 1中有两个连接波束，NR UE 1可以保存如下表1所示的信息：
表1
TRP 1 NAV
TRP 2 No
在NR UE 1收到TRP 1波束上的RTS后，随即保存NAV(Network Allocation Vector，网络分配矢量)，表示TRP 1上的波束存在干扰；此时NR UE 1可根据此表选择没有干扰的波束发送消息，例如选择TRP 2上的波束发送消息。
本申请实施例，在高频非授权频段，在多波束连接情况下，在其中一个或多个波束有同频干扰的情况下，通过其他没有干扰的波束发送干扰指示信息，干扰指示信息包括存在干扰的连接波束的索引信息和/或对应的保持静默时间，或者存在干扰的连接波束的索引信息和/或停止/恢复传输标识；该干扰指示信息可以通 过UCI或DCI发送；这样接收端可知道需要保持静默的时间，避免出现因为覆盖范围限制导致RTS或CTS没有被接收端接收，导致接收端不必要的功耗及形成不必要的干扰信号的情况发生，达到消除干扰的效果。

本申请实施例中，在高频非授权频段，在多波束连接情况下，在其中一个或多个波束有同频干扰的情况下，通过其他没有干扰的波束发送干扰指示信息，干扰指示信息包括存在干扰的连接波束的索引信息和/或对应的保持静默时间，或者存在干扰的连接波束的索引信息和/或停止/恢复传输标识；该干扰指示信息可以通过UCI或DCI发送；这样接收端可知道需要保持静默的时间，避免出现因为覆盖范围限制导致RTS或CTS没有被接收端接收，导致接收端不必要的功耗及形成不必要的干扰信号的情况发生，达到消除干扰的效果。
图11为本申请实施例七提供的一种通信设备的结构示意图。如图11所示，该通信设备包括：处理器1001、存储器1002。存储器1002存储计算机执行指令。其中，处理器1001执行存储器1002存储的计算机执行指令，使得处理器1001执行上述任一方法实施例中第一通信设备或者第二通信设备所执行的方法流程。
本申请实施例通过第一通信设备在确定第一连接波束上存在干扰时，则通过不存在干扰的第二连接波束发送用于指示第一连接波束存在干扰的干扰指示信息，第二通信设备通过第二连接波束接收干扰指示信息，可以及时地获知第一连接波束存在干扰的情况，并根据干扰指示信息，暂停使用第一连接波束进行通信，从而可以避免造成第二通信设备不必要的功耗及形成不必要的干扰信号，达到消除干扰的效果。
本申请还提供一种计算机存储介质，计算机存储介质上存储有计算机程序，计算机程序被处理器执行时实现如上任一方法实施例中第一通信设备或第二通信设备执行的方法的步骤。
本申请实施例还提供一种计算机程序产品，计算机程序产品包括计算机程序代码，当计算机程序代码在计算机上运行时，使得计算机执行如上各种可能的实施方式中的方法。
本申请实施例还提供一种芯片，包括存储器和处理器，存储器用于存储计算机程序，处理器用于从存储器中调用并运行计算机程序，使得安装有芯片的设备执行如上各种可能的实施方式中的方法。
需要说明的是，在本文中，采用了诸如S502、S503等步骤代号，其目的是为了更清楚简要地表述相应内容，不构成顺序上的实质性限制，本领域技术人员在具体实施时，可能会先执行S503后执行S502等，但这些均应在本申请的保护范围之内。
应该理解的是，虽然上述实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
本领域技术人员在考虑说明书及实践这里公开的发明后，将容易想到本申请的其它实施方案。本申请的实施例旨在涵盖本申请的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本申请的一般性原理并包括本申请未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本申请的真正范围和精神由下面的权利要求书指出。
