Description

信息反馈方法、装置及系统 技术领域
本公开涉及通信领域，具体而言，涉及一种信息反馈方法、装置及系统。
背景技术
高频技术作为未来第五代移动通信系统(5G)的重要候选技术，其可用的大带宽可以为未来通信提供高速率数据通信。但是高频技术相比现有LTE利用的低频载波，有其独特的传输特性。其显著特点就是路径损耗非常大，从而大大影响其通信距离，同时由于高频的波长比较短，可以在较小面积上放置很多的天线阵子，从而可以利用多天线技术形成高增益窄波束，抵抗路径损耗，增加小区覆盖，使得高频用于蜂窝通信成为可能。
基于波束通信的高频技术，在实际应用中发送端和接收端波束训练阶段建立链路之后，可能由于障碍物，或者发送端或者接收端的移动导致已经建立的链路失效。链路失效之后如何快速恢复链路是波束通信中的一个核心问题。现有技术中发送端通过在预留资源上重传数据和在相邻或者候选方向上发送数据，并等待接收端的确认信息，如果一直没有收到确认消息，从而判断链路失效，接收端通过在预留资源上接收重传数据，以及在相邻或者候选方向上接收分组，如果一直不能接收到分组，从而判断链路失效。总之，发送端只有多次重传尝试之后才会确定和接收端关联的发送链路失效了，或者接收端通过多次接收尝试之后才能判断链路失效，导致不必要的数据发送和预留资源的浪费以及数据发送时没有有效的链路可用导致的时延问题，特别是如果是发送端在相邻或者候选方向发送，接收端在相邻或者候选方向上接收时，所述通信链路也不可用时，问题更加严重。
针对相关技术中接收端和发送端无法及时获知通信链路失效导致资源利用率低的问题，目前还没有有效地解决方案。

可选地，M个优选发送链路的指示信息同时也可以但不限于用于指示如下信息中的至少之一：服务通信节点在第一发送链路上发送的信号到达第一通信节点的链路性能低于第一预定阀值；服务通信节点在第一发送链路上发送的信号无法到达第一通信节点；服务通信节点在除第一发送链路之外的其他预设发送链路上发送的信号到达第一通信节点的链路性能优于服务通信节点在第一发送链路上的链路性能；服务通信节点需停止在第一发送链路上向第一通信节点发送信号；第一通信节点将停止在第一发送链路上检测控制信息、接收数据、和/或跟踪链路；服务通信节点到第一通信节点链路性能比较优的M条优选发送链路。
实施方式三，图11是根据本公开可选实施例的确定反馈信息和发送反馈信息的方法的流程图三，如图11所示，第一通信节点首先判断触发条件是否满足，如果不满足继续检测，如果满足，向服务通信节点发送第一发送链路失效信息，并发送训练请求信号，然后获取M个优选发送链路指示信息，将指示信息发送给服务通信节点。在本实施方式中，第一通信节点也可以将训练请求信号和第一发送链路失 效信息一起发送给服务通信节点。
实施方式四，图12是根据本公开可选实施例的确定反馈信息和发送反馈信息的方法的流程图四，如图12所示，第一通信节点首先判断触发条件是否满足，如果不满足继续检测，如果满足，向服务通信节点发送训练请求信号，然后获取M个优选发送链路指示信息，将指示信息发送给服务通信节点。
可选地，在上述实施方式四中，训练请求信号还可以但不限于用于指示以下信息至少之一：服务通信节点在第一发送链路上发送的信号到达第一通信节点的链路性能低于第一预定阀值；服务通信节点在第一发送链路上发送的信号无法到达第一通信节点；服务通信节点在除第一发送链路之外的其他预设发送链路上发送的信号到达第一通信节点的链路性能优于服务通信节点在第一发送链路上的链路性能；服务通信节点需停止在第一发送链路上向第一通信节点发送信号；第一通信节点将停止在第一发送链路上检测控制信息、接收数据、和/或跟踪链路；所述训练请求信号请求服务小区发送训练信号。所述训练信号为发送方式和/或接收方式训练信号；第一通信节点请求服务通信节点发送训练信号，训练信号为发送方式的训练信号和/或接收方式的训练信号。
在上述实施方式中，训练请求信号为发送方式和/或接收方式训练请求信号，或者为波束训练请求信号，或者为波束跟踪请求信号，或者为发送方式和/或接收方式跟踪请求信号。
不同发送链路是服务通信节点发送信号采用的不同发送方式；第一发送链路是第一通信节点和服务通信节点之前建立的通信链路中对应于服务通信节点的发送方式，第一通信节点在第一发送链路上检测控制信道，和/和接收数据信号，和/或跟踪链路性能。其中，第一发送链路包括一个或者多个发送链路。
其中，服务通信节点指第二通信节点，和/或第三通信节点。
在上述实施方式中，触发条件，可以为如下条件中的一种或者多 种：
条件1：第一通信节点根据第二通信节点发送的信号，判断第一发送链路是否失效，当判断第一发送链路失效时，向服务通信节点发送反馈信息；
条件2：第一通信节点根据服务通信节点发送的触发信令信息向服务通信节点发送反馈信息；即服务通信节点发送信令指示第一通信节点向服务通信节点发送反馈信息，比如第二通信节点通过信令触发第一通信节点向第二通信节点发送所反馈信息，或者第三通信节点通过信令触发第一通信节点向第二通信节点发送所反馈信息。
条件3：第一通信节点根据服务通信节点配置的周期资源向服务通信节点发送反馈信息。
M个优选发送链路的指示信息包括如下信息中的一种或者多种：M个发送链路的索引信息，每个发送链路到达第一通信节点的链路性能信息，比如CQI信息。比如M个发送链路来自于N个候选发送链路，用N比特发送M个发送链路指示信息，其中对应比特值为1的发送链路为M个发送链路之一，对应比特值为0的发送链路不属于M个发送链路。需要说明的是，本可选实施例也不排除其他发送链路索引信息发送模式。
在本可选实施例中的一种第一通信节点向服务通信节点发送反馈信息的实施方式中，如图13是根据本公开可选实施例的发送反馈信息的方法的流程图一，如图13所示，第一通信节点在分配给他的专有资源上以第一发送方式向第二通信节点发送反馈信息，第一发送方式是第一通信节点和第二通信节点之前配置的最优发送方式。发送之后第一通信节点不侦听来自第二通信节点的确认信息，就认为反馈信息发送成功。
在本可选实施例中的另一种第一通信节点向服务通信节点发送反馈信息的实施方式中，如图14是根据本公开可选实施例的发送反馈信息的方法的流程图二，如图14所示，第一通信节点在专有资源 上第一发送方式发送反馈信息之后，在第一发送链路，和/或M个优选发送链路上侦听第二通信节点发送的确认信息，当连续预定次数的第一发送方式发送或者超过预定时间，没有收到第二通信节点的确认信息，第一通信节点以第二发送方式发送反馈信息，在第一发送链路，和/或M个优选发送链路上侦听第二通信节点发送的确认信息，依次类推，当第一通信节点遍历第一载频下的所有发送方式，仍未到第二通信节点发送的确认信息，认为反馈信息发送失败，启动小区切换请求，或者以第二载频向第二通信节点发送反馈信息。其中第一载频可以是高频，第二载频是低频，当收到确认信息之后，认为反馈信息发送成功。图14中不同发送方式对应的专有资源位置只是示例，并不排除其他占有情况。
在本可选实施例中的另一种第一通信节点向服务通信节点发送反馈信息的实施方式中，图15是根据本公开可选实施例的发送反馈信息的方法的流程图三，如图15所示，第一通信节点和第二通信节点约定在专有资源上用多个发送方式发送反馈信息给第二通信节点，如图15所示，第一通信节点依次以第一发送方式，第二发送方方式，第三发送方式发送反馈信息，发送完之后在第一发送链路，或者M个优选发送链路上，或者第二通信节点的其他发送链路上侦听来自第二通信节点的确认信息，当侦听到确认信息之后，认为反馈信息发送成功。图15中不同发送方式占有的专有资源是时分方式，本可选实施例也不排除其他形式，比如频分，和/或码分，和/或空分。
向服务通信节点发送反馈信息，本可选实施例的第四种实施方式中，第一通信节点直接以第二载频上的时频资源发送反馈信息，可以不侦听确认信息，直接认为反馈信息发送成功，或者在第二载频上侦听来自第二通信节点的确认信息，当侦听到确认信息之后认为发送成功，优选地，第二载频可以但不限于为LTE低频。
向服务通信节点发送反馈信息，本可选实施例的第五种实施方式中，第一通信节点当用上述发送方式向第二通信节点发送反馈信息之后，没有发送成功，比如没有收到第二通信节点，和/或第三通信节 点的确认信息，第一通信节点向第三通信节点发送反馈信息。优选地第三通信节点是低频节点。
向服务通信节点发送反馈信息，本可选实施例的第六种实施方式中，第一通信节点同时向第二和第三通信节点发送反馈信息，如果收到第二和第三通信节点中任意一个的确认信息，认为反馈信息发送成功。
向服务通信节点发送反馈信息，本可选实施例的第七种实施方式中，第一通信节点直接向第三通信节点发送反馈信息，优选地第三通信节点是低频节点。
向服务通信节点发送反馈信息，本可选实施例的第八种实施方式中，第一通信节点通过竞争方式向服务通信节点发送反馈信息，因为触发条件的满足可能是随机发生的，此时利用专有资源给服务通信节点发送反馈信息造成资源的浪费，此时可以基于竞争方式发送反馈信息，以竞争方式发送的一种实施方式是反馈信息中携带第一通信节点的识别信息，从而使得服务通信节点能够通过识别信息指导是共享竞争资源的多个通信节点中的哪一个发送的反馈信息。以竞争方式发送的另一种实施方式中，第一通信节点当需要发送反馈信息时，首先向第二通信节点发送请求信号，得到第二通信节点的响应信号之后，发送反馈信息，反馈信息中携带第一通信节点的识别信息。
其中，第一发送链路失效信息指示第二通信节点如下信息中的一种或者多种：第二通信节点在第一发送链路上发送的信号到达第一通信节点的链路性能低于第一预定阀值；第二通信节点在第一发送链路上发送的信号无法到达第一通信节点；第二通信节点在其他发送链路上发送的信号到达第一通信节点的链路性能优于其在第一发送链路上的链路性能；第二通信节点需要停止在第一发送链路上向第一通信节点发送信号；第一通信节点将停止在第一发送链路上检测控制信息，和/或数据接收，和/或链路跟踪。
第一发送链路和M个优选发送链路的本可选实施例的第一种实施方式是，第一发送链路和M个优选发送链路都是第二通信节点发 送的，属于第二通信节点发送的N个发送链路，不同发送链路对应第二通信节点的不同发送方式，如图6所示。
第一发送链路和M个优选发送链路的本可选实施例的第二种实施方式是，第一发送链路是第二通信节点发送的，M个优选发送链路是第三通信节点发送的，属于第三通信节点发送的N个发送链路，如图7所示。其中M小于等于N。
第一发送链路和M个优选发送链路的本可选实施例的第三种实施方式是，第一发送链路和M个优选发送链路属于第二通信节点和第三通信节点发送的N个发送链路，如图8所示。图8中发送链路编号只是示例，并不排除其他编号方式，总之是N个发送链路是第二通信节点和第三通信节点公共发送的。
M个优选发送链路是N个候选发送链路中到达第一通信节点链路性能最优的M个优选发送链路，和/或M个优选发送链路的链路性能都大于第二预定阀值。其中M小于等于N。
第一通信节点根据如下方式中的一种或者多种得到M值：根据N值；根据和服务通信节点约定的规则；根据N个候选发送链路到达第一通信节点的链路性能和第二预定阀值。比如
Figure PCTCN2017086635-appb-000001
其中R是第一通信节点和服务通信节点约定的大于0小于等于1的数，
Figure PCTCN2017086635-appb-000002
表示向下取整，或者M个优选发送链路由N个候选发送链路中到达第一通信节点的链路性能大于第二预定阀值的发送链路构成。
当第一通信节点和第二通信节点，和/或第三通信节点之前建立的通信链路包含多个发送链路时，比如包含发送链路{0,3,4}，其中0为最优发送链路，即第二通信节点，和/或第三通信节点可以在发送链路0,3,4上给第一通信节点发送信息，第一通信节点在{0,3,4}发送链路中的一个或者多个上检测控制信道，和/或接收数据，和/或跟踪链路性能。此时对于第一发送链路失效信息第一种实施方式是，第一通信节点判断发送链路上{0,3,4}到达第一通信节点的链路性能都低于第二预定阀值时才向第二通信节点，和/或第三通信节点发送第一发送链路失效信息。第二种实施方式中，第一通信节点判断发送链 路{0,3,4}中任意一个的到达第一通信节点的链路性能低于第二预定阀值时，第一通信节点发送第一发送链路失效信息，失效信息中指示失效的发送链路索引。比如链路性能低于预定阀值的发送链路为链路3，第二通信节点，和/或第三通信节点接收到第一发送链路指示信息之后，停止在所示指示的链路上，即发送链路3上向第一通信节点发送信息，可以在发送链路{0,4}上向第一通信节点发送信息。
当触发条件为第一通信节点判断第一发送链路是否失效时，由于第一发送链路失效的发生是随机的，如果基于随机方式发送反馈信息，资源利用率不高，而且增加第二通信节点，和/或第三通信节点的检测复杂度。此时第一通信节点可以进一步判断当前是否处于数据活跃期，当处于数据活跃期基于非周期资源上快速发送反馈信息，如果当前处于非数据活跃期，基于分配的周期资源上发送反馈信息。其中数据活跃期，表示当前时刻距离第一通信节点最新接收第二通信节点发送的数据之间的距离没有超过预定的时间，和/或当前时刻距离第一通信节点最新给第二通信节点发送数据之间的距离没有超过预定的时间。
可选实施例2
在本可选实施例中与可选实施例1的过程类似，主要区别是第一通信节点根据第二通信节点在控制信道资源上发送的解调参考信号，判断触发条件是否满足，即判断第一发送链路是否失效，如第一发送链路失效，即触发条件满足。
其中，不同控制信道资源的区别特征包括：第二通信节点发送控制信道资源所采用的发送波束，和/或发送端口，和/或发送预编码矩阵，和/或发送时间，和/或发送频率，和/或发送载频。一个控制信道资源对应一个发送链路，一个发送链路对应一个或者多个控制信道资源，对应关系是第一通信节点和第二通信节点事先约定好的。其中一个控制信道资源携带用于解调本控制信道资源信号的解调参考信号。假如总共有4个控制信道资源，4个发送链路，其对应关系为表1所示：
表1：控制信道和发送链路之间的对应关系
Figure PCTCN2017086635-appb-000003
或者总共有8个控制信道资源，4个发送链路，其对应关系如表2所示：
表2：控制信道和发送链路之间的对应关系
Figure PCTCN2017086635-appb-000004
表1和表2只是示例，并不排除其他的对应关系。当如表2所示，一个发送链路对应一个以上的控制信道资源时，第一通信节点根据多个控制信道资源对应的解调参考信号接收性能判断和第二通信节点 关联的发送链路是否失效。
在监听解调参考信号的接收性能之前，第一通信节点通过如下方式得到一个或者多个控制信道资源对应的资源信息：根据和第二通信节点约定的规则；根据第二通信节点发送的信令信息；根据第四通信节点发送的信令信息。
对于控制信道资源的资源信息本可选实施例的第一种实施方式中第一通信节点和第二通信节点约定每个控制信道资源的资源信息。图16是根据本公开可选实施例的控制信道资源的占有情况的示意图一，如图16所示，第一通信节点和第二通信节点约定在每个时间单元中的控制域发送的控制资源情况，图中索引为0～3的控制资源是时分的方式，当然本可选实施例也不排除频分的方式，图中时分方式下一个时间内只对应一个控制信道资源，本可选实施例也不排除一个时间内对应多个控制信道资源的情况，图17是根据本公开可选实施例的控制信道资源的占有情况的示意图二，如图17所示，图16与图17中控制信道资源占有情况只是示例，并不排除其他占有情况，总之表示每个时间单元中发送全部的控制信道资源。或者，图18是根据本公开可选实施例的控制信道资源的占有情况的示意图三，如图18所示，控制信道资源集按轮询方式在不同时间单元中发送不同的控制信道资源。在图16至图18中第一通信节点和第二通信节点约定的控制信道资源上，不管其上是否有控制信息需要发送，第二通信节点肯定发送控制信道对应的解调参考信号，从而使得第一通信节点根据控制信道资源上的解调参考信号的接收性能判断第一发送链路是否失效。即第二通信节点在约定的控制资源上上至少发送控制资源解调参考信号。
对于控制信道资源的资源信息本可选实施例的第二种方式是第一通信节点根据第二通信节点发送的信令信息得到控制信道资源所在的资源信息，比如根据第二通信节点发送的高层信令，得到每个控制信道资源在时间单元中的发送情况，图19是根据本公开可选实施例的控制信道资源的占有情况的示意图四，如图19所示，索引为i 时间单元中，第二通信节点通过动态信令信息，或者高层信令信息通知索引为i+K1时间单元中发送的控制信道资源情况，其中K1是大于等于0的正整数。图20是根据本公开可选实施例的控制信道资源的占有情况的示意图五，如图20所示，索引为i时间单元中，第二通信节点通过动态信令信息，或者高层信令信息通知i+K1时间单元之后一个测量周期内的各个时间单元中控制信道的发送情况，第一通信节点根据测量周期内各个控制信道资源的对应的解调参考信号的接收性能判断对应发送链路是否失效。或者此时第二通信节点仅通知第一发送链路对应的控制信道资源所在的资源，第一通信节点根据第一发送链路对应的控制信道资源上的解调参考接收性能判断第一发送链路是否失效，图21是根据本公开可选实施例的控制信道资源的占有情况的示意图六，如图21所示，假如第一发送链路对应的控制信道资源为索引为0的控制信道资源，第二通信节点仅通知一个测量周期内控制信道资源索引为0所在的资源，第一通信节点根据一个测量周期中通知控制信道资源为0的资源上的解调参考信号判断第一发送链路是否失效。当然此时在一个测量周期中其他资源上可能发送也可能不发送索引为0的控制信道，但是在通知所示的控制信道资源上第二通信肯定发送索引为0的控制信道资源对应的解调参考信号。
对于控制信道资源的资源信息本可选实施例的第三种实施方式中，第一通信节点根据第四通信节点发送的信令信息或者非信令信息得到每个控制信道资源所在的资源，在所通知控制信道资源上，第二通信节点至少发送控制资源对应的解调参考信号,以便于第一通信节点根据解调参考信号判断发送链路是否失效。图22是根据本公开可选实施例的控制信道资源的占有情况的示意图七，如图22所示，第四通信节点通知每个时间单元中第二通信节点在控制域发送的控制信道资源情况。第二通信节点在通知的控制信道资源上至少发送控制信道资源对应的解调参考信号。
在图16中每个时间单元中第二通信节点都要发送所有控制信道资源对应的解调参考信号，对于控制信道资源的资源信息本可选实施 例的第四种实施方式中，第一通信节点和第二通信节点约定需要发送所有控制信道资源的解调参考信号的时间单元是非连续的，而是具有一定的规则，比如只有索引号为T的整数倍的时间单元中发送，其他时间单元中控制信道资源根据需求灵活发送，即至少不需要发送第二通信节点所有控制信道资源对应的解调参考信号。图23是根据本公开可选实施例的控制信道资源的占有情况的示意图八，如图23所示，假如第二通信节点总共有4个控制信道资源，只有在索引为T的整数倍的时间单元中至少需要发送这4个控制信道资源对应的解调参考信号，在其他时间单元中，比如索引为i+1～索引为i+T-1的时间单元中控制信道资源的发送根据需求灵活发送。第二通信节点在约定的控制信道资源上至少发送控制信道资源对应的解调参考信号。
对于根据控制信道资源上的解调参考信号判断第一发送链路是否失效，本可选实施例的第一种实施方式中，第一通信节点首先以第一接收方式接收第一发送链路对应的控制信道资源上的信号，判断解调参考接收性能，如果接收性能大于第一预定阀值，继续进行后续时间单元中第一发送链路对应的控制信道资源上的解调参考信号接收性能的检测，当第一发送链路对应的控制信道资源上的解调参考信号接收性能低于第一预定阀值，判断第一发送链路失效。本可选实施例的第二种实施方式中，第一通信节点首先以第一接收方式接收第一发送链路对应的解调参考信号，以第一接收方式或者全向方式接收其他发送链路对应的解调参考信号，得到最优接收性能，当所述其他发送链路对应的最优接收性能与第一发送链路对应的接收性能的差值大于第三预定阀值时，判断第一发送链路失效。
当检查到第一发送链路失效之后，本可选实施例的第一种实施方式是第一通信节点当判断出现一次第一发送链路失效之后，盘查第一发送链路失效，即判断触发条件满足，开始准备向服务通信节点发送反馈信息。本可选实施例的第二种实施方式是第一通信节点当检测到第一发送链路失效N1次之后，才认为触发条件满足，N1是第一通信节点和第二通信节点事先约定的。
上述实施方式中，第一通信节通过检测控制信道资源上的解调参考信号判断第一发送链路是否失效，当第一发送失效时，认为触发条件满足，从而确定反馈信息，发送反馈信息，本可选实施例的第二种实施方式中，第一通信节点通过检测控制资源上的解调参考信号，周期向服务通信节点发送反馈信息。
本可选实施例的另一种实施方式中，第一通信节点通过检测第二通信节点发送的数据信道资源上的解调参考信号，检测触发条件是否满足，当满足触发条件时，确定反馈信息，向服务通信节点发送反馈信息。
本可选实施例的另一种实施方式中，第一通信节点根据第二通信节点和/或第三通信节点在控制信道资源上发送的解调参考信号，判断触发条件是否满足，即判断第一发送链路是否失效，如第一发送链路失效，即触发条件满足。
可选实施例3
在本可选实施例中与可选实施例1的过程类似，主要区别是第一通信节点根据第二通信节点在第一发送链路上发送的探测信号判断触发条件是否满足。
本可选实施例的第一种实施方式中，当第一通信节点和第二通信节点已建立了第一发送链路之后，第二通信节点向第一通信节点发送非周期触发信令，然后依据触发信令在第一发送链路上发送探测信号。或者第三通信节点向第一通信节点发送非周期触发信令，第二通信节点依据触发信令在第一发送链路上发送探测信号。第一通信节点根据探测信号判断第一发送链路是否失效，向第二通信节点发送反馈信息。反馈信息至少包括如下信息之一：第一发送链路失效信息，第一发送链路没有失效信息，第一发送链路上的接收质量信息。图24是根据本公开可选实施例的第一发送链路探测信号的资源占有情况的示意图一，如图24所示，非周期触发信号通知多个时间单元中的第一发送链路探测信号，第一通信节点根据图中所示的多个第一发送链路探测信号判断触发条件是否满足，如果触发条件满足，向第二通信节点 发送反馈信息，图中各个时间单元中第一发送链路探测信号的资源信息只是示例，并不排除其他资源占有情况。图25是根据本公开可选实施例的第一发送链路探测信号的资源占有情况的示意图二，如图25所示，非周期触发信号只触发一个时间单元中的第一发送链路探测信号。其中第一发送链路探测信号占有的资源信息或者由非周期触发信令通知，或者根据约定的规则得到。
本可选实施例的第二种实施方式中，当第一通信节点和第二通信节点已建立了第一发送链路之后，第一通信节点根据第二通信节点周期发送的第一发送链路探测信号，得到第一发送链路的接收质量情况，当满足触发条件时，向第二通信节点发送反馈信息。图26是根据本公开可选实施例的第一发送链路探测信号的资源占有情况的示意图三，如图26所示，第二通信节点周期发送第一发送链路探测信号。
在上述实施方式中，在图24至图25中每个第一发送链路探测信号可以包括多个符号，使得第一通信节点可以改变接收方式接收第一发送链路探测信号。其中触发条件一种实施方式是第一通信节点在非周期触发信令之后，不论第一发送链路是否失效都向第二通信节点发送反馈信息。触发条件的另一种实施方式是只有第一发送链路失效时，才向第二通信节点发送反馈信息。
在上述实施方式中，优选地第一发送链路探测信号触发信令的目标节点只有第一通信节点。
本可选实施例的另一种实施方式中，第一通信节点根据第二通信节点和/或第三通信节点在第一发送链路上发送的探测信号判断触发条件是否满足。
可选实施例4
本可选实施例和可选实施例1的过程类似，主要区别特征在于，第一通信节点根据第二通信节点发送的训练信号，判断触发条件是否满足，当触发条件满足时，向服务通信节点发送反馈信息。
本可选实施例的第一种实施方式中，训练信号周期发送。图27 是根据本公开可选实施例的训练信号的资源一种占有情况的示意图，如图27所示，第一通信节点根据第二通信节点周期发送的训练信号，判断触发条件是否满足，当触发条件满足时，向服务通信节点发送反馈信息。图中发送链路组对应的训练信号的个数和所占的资源只是示例，并不排除其他训练信号个数和所占的资源情况。此时优选地训练信号包含第二通信节点的所有发送链路。
本可选实施例的第二种实施方式中，训练信号非周期发送，训练信号根据非周期训练信号信令信息发送，第一通信节点根据第二通信节点非周期发送的训练信号，判断触发条件是否满足，当触发条件满足时，向服务通信节点发送反馈信息。此时训练信号包含N个发送链路，N个发送链路第一种实施方式是包含第二通信节点所有发送链路，比如第二通信节点总共有16个发送链路，N个发送链路为16个发送链路，第二种实施方式是N个发送链路包含第二通信节点和第一通信节点约定的所有发送链路的一个子集，比如约定第二通信节点和第一通信节点之间的N个发送链路是发送链路0～7总共8个发送链路，第三种实施方式是N个发送链路是第一发送链路相邻的多个发送链路，或者第一发送链路对应的发送链路子集。
训练信号为发送方式和/或接收方式训练信号，或者波束训练信号，或者是波束跟踪信号，或者为发送方式和/或接收方式跟踪信号。
上述实施方式中触发条件一种方式是第一通信节点不论第一发送链路是否失效周期向第二通信节点发送反馈信息。触发条件的另一种方式是只有第一发送链路失效时，第一通信节点才向第二通信节点发送反馈信息。
在上述实施方式中，训练信号的通知信令信息的目标节点或者只有第一通信节点，或者是第二通信节点覆盖下的所有通信节点，或者是第二通信节点覆盖下的部分通信节点，即一个通信节点组。
在本可选实施例的另一种实施方式中，第一通信节点根据第二通信节点和第三通信节点发送的训练信号，或者根据第三通信节点发送的训练信号，判断触发条件是否满足，当触发条件满足时，向服务通 信节点发送反馈信息。
可选实施例5
本可选实施例和可选实施例1中的过程类似，主要区别特征在于第一通信节点根据第二通信节点发送的控制信道资源上的解调参考信号从N个候选发送链路中获取M个优选发送链路的方式，其中M小于等于N。
其中不同控制信道资源的区别特征包括：第二通信节点发送控制信道资源所采用的发送波束，和/或发送端口，和/或发送预编码矩阵，和/或发送时间，和/或发送频率，和/或发送载频。一个控制信道资源对应一个发送链路，一个发送链路对应一个或者多个控制信道资源，对应关系是第一通信节点和第二通信节点事先约定好的。
N个候选发送链路第一种实施方式是包含第二通信节点所有发送链路，比如第二通信节点总共有16个发送链路，N个候选发送链路为16个发送链路，第二种实施方式是N个候选发送链路包含第二通信节点和第一通信节点约定的所有发送链路的一个子集，比如约定第二通信节点和第一通信节点之间的N个候选发送链路是发送链路0～7总共8个发送链路，第三种实施方式是N个候选发送链路是第一发送链路相邻的多个发送链路，或者第一发送链路对应的发送链路子集。
根据N个候选发送链路的链路性能得到M个优选发送链路，本可选实施例的第一种实施方式中，在判断第一发送链路失效的时间单元中根据其他发送链路的链路性能得到M个优选发送链路，此时每个候选链路对应的第一通信节点的接收方式只有一个。图28是根据本公开可选实施例的第一通信节点通过一个接收方式获取M个优选发送链路的示意图，如图28所示，在索引为0的时间单元中判断出第一发送链路失效，且假设第一发送链路为索引为0的发送链路，那么此时接收端是以第一接收方式接收索引为0的发送链路控制信道资源，以第一接收方式或者全向方式接收索引为1～3的发送链路控制信道资源，且假设N个候选发送链路为索引为0～3(或者1～3)的候 选发送链路,此时第一通信节点根据索引为0的时间单元中的控制信道资源对应的解调参考信号接收性能得到M个优选发送链路。
根据N个候选发送链路的链路性能得到M个优选发送链路，本可选实施例的第二种实施方式中，图29是根据本公开可选实施例的第一通信节点在不同时间单元变换接收方式获取M个优选发送链路的示意图，如图29所示，第一通信节点遍历其接收方式，得到M个优选发送链路，保存各个每个优选发送链路对应的接收方式。
根据N个候选发送链路的链路性能得到M个优选发送链路，本可选实施例的第三种实施方式中，图30是根据本公开可选实施例的第一通信节点在一个时间单元上变换接收方式获取M个优选发送链路的示意图一，如图30所示，一个时间单元中，一个发送链路控制资源包含多个符号或者符号组，使得第一通信节点当判断第一发送链路失效时，在当前时间单元遍历所有接收方式，从N个候选发送链路中得到M个优选发送链路，当然在没有判断出第一发送链路失效时，第一通信节点最好对于N个候选链路中非第一发送链路按不同接收方式接收，从而当判断出第一发送链路失效之后可以基于当前时间单元信号得到M个优选发送链路，从而可以减少得到M个优选发送链路的时延。或者，图31是根据本公开可选实施例的第一通信节点在一个时间单元上变换接收方式获取M个优选发送链路的示意图二，如图31所示，图30和图31相比，图30第一通信节点对应的接收射频波束切换比较频繁，图31中第二通信节点对应的发送射频波束切换比较频繁。图中每个发送链路控制资源包含的符号个数只是示例并不排除其他符号个数情况，图中N的个数也只是示例并不排除其他N值情况。
在上述实施方式中，第一通信节点可以对于N个候选发送链路中的每个发送链路仅采样一次判断其接收性能从而得到M个优选发送链路，也可以在一个测量周期中采样多次，基于多次采样得到平均接收性能，从而得到M个优选发送链路。
在上述实施方式中，N个发送链路对应的控制资源所占的资源可 以通过类似可选实施例2的方式得到。
在上述实施方式中，当第一通信节点根据N个候选发送链路对应的控制信道资源上的解调参考信号无法得到M个优选发送链路时，比如N个候选发送链路的接收性能都低于第二预定阀值，第一种实施方式是第一通信节点向服务通信节点发送小区切换请求信号，第二种实施方式第一通信节点向第二通信节点发送训练请求信号，根据之后服务通信节点发送的训练信号得到M个优选发送链路，如果根据训练信号也不能得到M个优选发送链路时，向服务通信节点发送小区切换请求信号，或者启动小区搜索流程。其中服务通信节点指第二通信节点，和/或第三通信节点。
在本可选实施例的另一种实施方式中，第一通信节点根据第二通信节点和/或第三通信节点发送的控制信道资源上的解调参考信号从N个候选发送链路中获取M个优选发送链路的方式，其中M小于等于N。
可选实施例6
本可选实施例和可选实施例1的过程类似，主要区别特征是第一通信节点通过训练信号，获得M个优选发送链路的指示信息。
训练信号可以是第二通信节点基于训练请求信号发送的，此时训练信号占有的资源根据如下信息中的一种或者多种得到：训练请求信号，训练请求信号占有的资源，第二通信节点发送的信令信息。此时训练信号包含N个候选发送链路。
N个候选发送链路第一种实施方式是包含第二通信节点所有发送链路，比如第二通信节点总共有16个发送链路，N个候选发送链路为16个发送链路，第二种实施方式是N个候选发送链路包含第二通信节点和第一通信节点约定的所有发送链路的一个子集，比如约定第二通信节点和第一通信节点之间的N个候选发送链路是发送链路0～7总共8个发送链路，第三种实施方式是N个候选发送链路是第一发送链路相邻的多个发送链路，或者第一发送链路对应的发送链路子 集。
训练信号第二种实施方式是第二通信节点周期发送N个候选发送链路，优选地N个候选发送链路包含第二通信节点的所有发送链路。
训练信号第三种实施方式是基于第一发送链路失效信息进行发送，其中训练信号的发送方式和其占有的资源根据如下信息中的一种或者多种得到：第一发送链路失效信息，第一发送链路相关信息，第一通信节点发送第一发送链路失效信息的发送方式，服务通信节点接收第一发送链路失效信息的接收方式。其中训练信号指发送方式和/或接收方式训练信号。
训练信号可以是发送方式和/或接收方式训练信号，或者是波束训练信号。或者是波束跟踪信号，或者是发送方式和/或接收方式跟踪信号。
在上述实施方式中，当第一通信节点根据N个候选发送链路对应的训练信号无法得到M个优选发送链路时，比如N个候选发送链路的接收性能都低于第二预定阀值，第一通信节点向服务通信节点发送小区切换请求信号。
在本可选实施例的另一种实施方式中，训练信号是第二通信节点和/或第三通信节点发送的。
可选实施例7
在本可选实施例中，第一通信节点根据反馈信息，和/或根据服务通信节点发送的响应信息，调整其与服务通信节点的通信链路。其中服务通信节点包括第二通信节点，和/或第三通信节点。
本可选实施例的第一种实施方式，图32是根据本公开可选实施例的第一通信节点发送反馈信息之后调整通信链路的方法的流程图一，如图32所示，第一通信节点给服务通信节点发送第一发送链路失效信息之后，调整其与服务通信节点的通信链路，在调整后的通信链路上检测控制信道，和/或数据接收，和/或链路跟踪。此时第一通 信节点认为其以较高概率发送成功第一发送链路失效信息，即以较高的鲁棒性发送第一发送链路失效信息，比如较低码率，和/或较多波束，和/或较宽波束,或者低频发送。
本可选实施例的第二种实施方式，图33是根据本公开可选实施例的第一通信节点发送反馈信息之后调整通信链路的方法的流程图二，如图33所示，第一通信节点向服务通信节点发送第一发送链路失效信息之后，侦听服务通信节点发送的确认信息，当侦听到确认信息之后，调整与服务通信节点的通信链路，在调整后的通信链路上检测控制信道，和/或数据接收，和/或链路跟踪。当超过预定时间没有侦听到确认信息，认为发送失败，此时可能也已经经过了多次重复发送，所以此时开启小区切换流程。
在上述实施方式一和二中，调整其与服务通信节点的通信链路，比如将第一通信节点对应的第二通信节点的发送链路切换为第二发送链路。其中第二发送链路是第一通信节点和第二通信节点约定当发生第一发送链路失效时切换到的发送链路，或者当发生第一发送链路失效后根据第一发送链路得到的发送链路，其中第二发送链路可以有一个或者多个发送链路。第一种方式是第二发送链路是第二通信节点和第二通信节点之间接收质量次于第一发送链路的发送链路；第二种方式是第二发送链路为全向链路，比如第二发送链路包含第二通信节点的所有发送链路；第三种方式是第二发送链路为更宽的波束；第四种方式是第二发送链路是低频发送链路；第五种方式是第二发送链路是来自第三通信节点的固定发送链路。第一通信节点在所示第二发送链路上检测控制信道，和/或数据接收，和/或链路跟踪。

本可选实施例的第四种实施方式，图35是根据本公开可选实施例的第一通信节点发送反馈信息之后调整通信链路的方法的流程图四，如图35所示，第一通信节点向服务通信节点发送M个优选发送链路之后，侦听服务通信节点发送的确认信息，当侦听到确认信息之后，调整与服务通信节点的通信链路，在调整后的通信链路上检测控制信道，和/或数据接收，和/或链路跟踪。当超过预定时间认为侦听到确认信息，认为发送失败，此时可能也已经经过了多次重复发送，所以此时开启小区切换流程。
上述实施第三和第四实施方式中，第一通信节点调整其与服务通信节点的通信链路，第一种实施方式是，第一通信节点立即将其与服务通信节点的通信链路更换为M个优选发送链路，或者更换为M个优选发送链路中的部分发送链路。第二种实施方式中，第一通信节点在固定时间之后，将其通信链路更换为M个优选发送链路，或者更换为M个优选发送链路中的部分发送链路，在更换之前，第一通信节点仍然在第一发送链路上进行控制信道的检测，和/或数据接收，和/或链路跟踪。更换之后，在更换的发送链路上进行行控制信道的检测，和/或数据接收，和/或链路跟踪。
上述实施方式中，侦听来自服务通信节点的确认信息，第一种方式是在第一发送链路上侦听，第二种方式如果反馈信息包括M个优选发送链路，则在M个优选发送链路中的一个或者多个发送链路上侦听确认信息；第三种方式是，如果服务通信节点和第一通信节点之前建立的链接中发送链路包含多个，比如发送链路{0,3,4}，而第一发送链路失效指示信息指示发送链路0失效，则第一通信节点在发送链路3,和/或发送链路4上侦听确认信息。
可选实施例8
在本可选实施例中，服务通信节点检测和接收第一通信节点发送的反馈信息，当检测和接收到第一通信节点发送的反馈信息之后，发 送响应的信号，和/或调整与第一通信节点之间的通信链路。其中服务通信节点指第二通信节点，和/或第三通信节点。
当第一通信节点在专有资源上周期上报反馈信息时，服务通信节点只在周期资源上检测，其他资源上不检测反馈信息。当第一通信节点在专有资源上随机发送反馈信息时，服务通信节点在在专有资源的任意资源上都需要检测第一通信节点发送的反馈信息。
