Description

一种控制信道的检测方法、装置及系统 技术领域
本公开涉及通信领域，尤其涉及一种控制信道的检测方法、装置及系统。
背景技术
在无线通信系统中，基站会利用多根天线的波束成型能力，采用窄波束传输来有效提升传输效率。但是，利用窄波束传输对用户设备(UE)移动和波束链路的阻塞会比较敏感，尤其是在高频中，阻塞现象比较严重，经常会引起波束链路的失效。因此，当无线信道因为上述原因产生信道变化时，通信系统需要快速进行波束链路的切换和恢复，才能提供好的用户体验。

具体实施方式
为使本公开的发明目的、技术方案和有益效果更加清楚明了，下面结合附图对本公开 的实施例进行说明，需要说明的是，在不冲突的情况下，本申请中的实施例和实施例中的特征可以相互任意组合。
在最新5G无线通讯系统中，5G接收端(基站)则采用了大规模天线阵列，通过波束形成(beamforming)技术对无线信号的能量产生聚焦，即形成一个指向性波束(Beam)，为保证最终得到足够的信号增益，大规模天线阵列所产生的波束通常需要变得很窄，付出的代价是，接收端(基站)需要使用大量的窄波束才能保证小区内任意方向上的用户都能得到有效覆盖，即波束越窄，信号增益越大。但是，利用窄波束传输对用户设备(UE)移动和波束链路的阻塞会比较敏感，尤其是在高频中，阻塞现象比较严重，经常会引起波束链路的失效。因此，当无线信道因为上述原因产生信道变化时，通信系统中的发送端(终端)需要快速与接收端(基站)进行波束链路的切换和恢复，才能提供好的用户体验。
实施例一
图2为本公开实施例一提供的一种控制信道的检测方法的流程示意图，如图2所示，本实施例一提供一种控制信道的检测方法，应用于发送端(终端)，该方法包括：
步骤S101：上报波束恢复的指示信息。
示例性的，发送端(终端)对波束进行监测，该监测过程主要是通过参考信号进行波束失效(beam failure)的判断，如果在需要进行波束恢复时，发送端(终端)会上报用于波束恢复的指示信息，该指示信息例如可以是发送端(终端)的指示信息、波束指示信息等。
步骤S102：在上报所述指示信息之后，检测M个控制区域，其中，M>1，M为整数。
示例性的，发送端(终端)在上报所述指示信息之后，开始检测M个控制区域，其中，M>1，M为整数，可以根据波束恢复的实际情况配置M个控制区域，例如：根据波束恢复的三个过程，配置一个波束恢复前的第一控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；配置一个在波束恢复时的第二控制区域会，第二控制区域一般也是接收端(基站)通过高层信令配置，为波束恢复期间需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；配置一个在波束恢复后的第三控制区域，第三控制区域一般也是接收端(基站)通过高层信令配置，为波束恢复后需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；但并不以此为限。
可选的，所述M个控制区域中，包括：至少一个第一控制区域和至少一个第二控制区域，其中，所述第一控制区域为在上报波束恢复的指示信息之前需要检测的控制区域，所述第二控制区域为用于接收波束恢复响应的控制区域。
示例性的，检测这M个控制区域中，至少包括两个控制区域，可以是第一控制区域 和第二控制区域，其中，该第一控制区域为上报波束恢复的指示信息之前需要检测的控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；第二控制区域为接收波束恢复响应的控制区域，第二控制区域一般也是接收端(基站)通过高层信令配置，为波束恢复期间需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；波束恢复之前接收端(基站)会发送相应的配置信令，当波束失效后,发送端(终端)会选择新的波束并上报给接收端(基站)，在上报新的波束指示信息之后，延迟几个时隙就会开始检测第二控制区域，虽然开始检测第二控制区域，但第一控制区域内仍然进行检测，接收基站发送的控制信令，由此可见，发送端(终端)在分别检测第一控制区域和第二控制区域的时间段可以是部分重叠也可以是全部重叠，但并不以此为限。
步骤S103：若在所述M个控制区域的任意一个控制区域检测到控制区域参数的配置变更信令，则按照所述配置变更信令进行控制信道的检测。
示例性的，在M个控制区域的任意一个控制区域检测到控制区域参数的配置变更信令，包括：第一控制区域配置变更信令，例如：该配置变更信令的信息可以是配置变更第一控制区域，可以是配置变更第一控制区域的波束或者时频资源位置等，具体根据配置变更信令里的指示信息，变更第一控制区域的波束一般是采用传输状态指示(Transmission State Indication)信息来实现的，并不以此为限。
例如,发送端(终端)在第一控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为第一控制区域的波束，发送端(终端)按照新的波束配置对第一控制区域进行检测，第二控制区域失效，可以结束对第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第二控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为第一控制区域的波束，发送端(终端)按照新的波束配置对第一控制区域进行检测，第二控制区域失效，可以结束对第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第一控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为新的控制区域(第三控制区域)的指示信息，发送端(终端)配置变更信令对该第三控制区域进行检测，第一和第二控制区域失效，可以结束对第一和第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第二控制区域内收到了控制信道配置变更信令，发送端(终 端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为新控制区域(第三控制区域)的指示信息，发送端(终端)配置变更信令对第三控制区域进行检测，第一和第二控制区域失效，发送端(终端)可以结束对第一和第二控制区域的检测，发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
上述实施例中提到的失效，意味着即使在该区域检测到控制信令也不会被认为是有用控制信令。
然后，发送端(终端)如果只是配置变更第一控制区域的波束，那么第三控制区域和第一控制区域实际是相同的。
本公开实施例提供一种控制信道的检测方法，通过在上报所述指示信息之后，检测M个控制区域，其中，M>1，M为整数，若在所述M个控制区域的任意一个控制区域检测到控制区域参数的配置变更信令，则按照所述配置变更信令进行控制信道的检测，使得可以提高控制信道检测的鲁棒性，从而降低通信系统中链路失效的概率。
实施例二
图3为本公开实施例二提供的一种控制信道的检测方式的示意图，如图3所示，在本实施例二中，根据波束恢复的三个过程，假设M为3，配置一个波束恢复前的第一控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；配置一个在波束恢复时的第二控制区域，第二控制区域一般也是基站通过高层信令配置，为波束恢复期间需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；波束恢复之前接收端(基站)会发送相应的配置信令，当波束失效后,发送端(终端)会选择新的波束并上报给接收端(基站)，在上报新的波束指示信息之后，延迟几个时隙就会开始检测第二控制区域，虽然开始检测第二控制区域，但第一控制区域内仍然进行检测，接收基站发送的控制信令，配置一个在波束恢复后的第三控制区域，第三控制区域一般也是基站通过高层信令配置，为波束恢复后需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；其中，发送端(终端)在检测第一控制区域的时间为T1，在检测第二控制区域的时间为T2，在检测第三控制区域的时间为T3，可以从图3中看出，T1和T2是大部分时间是重叠的，即发送端(终端)在T1和T2重叠的时间内同时检测第一控制区域和第二控制区域。
发送端(终端)分别在T1时间内检测第一控制区域和在T2时间内检测第二控制区域时，如果在在T1时间内或者T2时间内在第一控制区域和第二控制区域中任意一个控制区域检测到控制区域参数的配置变更信令，该配置变更信令包括：第一控制区域配置变更信令，例如：该配置变更信令的信息可以是配置变更第一控制区域，可以是配置变更第 一控制区域的波束或者时频资源位置等，具体根据配置变更信令里的指示信息，变更第一控制区域的波束一般是采用传输状态指示(Transmission State Indication)信息来实现的，并不以此为限。
例如,发送端(终端)在第一控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为第一控制区域的波束，发送端(终端)按照新的波束配置对第一控制区域进行检测，第二控制区域失效，可以结束对第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第二控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为第一控制区域的波束，发送端(终端)按照新的波束配置对第一控制区域进行检测，第二控制区域失效，可以结束对第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第一控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为新的控制区域(第三控制区域)的指示信息，发送端(终端)配置变更信令对该第三控制区域进行检测，第一和第二控制区域失效，可以结束对第一和第二控制区域的检测。发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
例如,发送端(终端)在第二控制区域内收到了控制信道配置变更信令，发送端(终端)根据控制信道配置变更信令进行控制信道检测。配置变更信令为新控制区域(第三控制区域)的指示信息，发送端(终端)配置变更信令对第三控制区域进行检测，第一和第二控制区域失效，发送端(终端)可以结束对第一和第二控制区域的检测，发送端(终端)可以重置用于波束恢复过程的定时器和/或计数器。
上述实施例中提到的失效，意味着即使在该区域检测到控制信令也不会被认为是有用控制信令。
可以从图3中看出，发送端(终端)如果只是配置变更第一控制区域的波束，那么第三控制区域和第一控制区域实际是相同的。
实施例三
图4为本公开实施例三提供的一种控制信道的检测方式的示意图，如图4所示，在本实施例三中，根据波束恢复的三个过程，假设M为3，配置一个波束恢复前的第一控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；配置一个在波束恢复时的第二控制区域，第二控制区域一般也是基站通过高层信令配置，为波束恢复期间 需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；配置一个在波束恢复后的第三控制区域，第三控制区域一般也是基站通过高层信令配置，为波束恢复后需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；其中，发送端(终端)在检测第一控制区域的时间为T1，在检测第二控制区域的时间窗为T2，在检测第三控制区域的时间为T3，可以从图4中看出，T2时间窗是一段固定的时间值，即发送端(终端)在T2时间窗内在检测第一控制区域的同时也在检测第二控制区域。
从图4中可以看出，发送端(终端)在检测该第二控制区域对应的检测时间窗T2内，如果第二控制区域中没有收到重配信息，仍然可以检测第一控制区域来获取配置变更信令，即在T2时间窗外，发送端(终端)检测所述第一控制区域时，如果检测到控制区域参数的配置变更信令，则按照所述配置变更信令进行控制信道的检测，并且认为波束恢复成功。
由上述实施例可知，波束恢复过程是有时间窗的，如果波束恢复时间窗超过后，仍然没有收到控制区域配置变更信息。发送端(终端)在一段时间后会判断链路失效发起重新接入，但在发起重新接入之前，接收端(基站)仍然可以检测第一控制区域来获取配置变更信息，如果检测到配置变更信息，则按照基站发送的重配信令进行控制信道检测，并且认为波束恢复成功，发送端(终端)暂时不会触发无线链路失效RLF对应的重新接入过程。一般会修改用于无线链路失效RLF判断的参数取值。
需要说明的是，上述实施例中的第一、二、三控制区域在时间维度上并不一定是每个时隙都存在的，同一控制区域内的资源是采用同一套配置信令进行配置的，控制区域可以存在周期、时隙偏移，所属的频域子带(BWP，bandwidth part)/通信载波(CC，carrier)等参数。
可选地，发送端(终端)在所述M个控制区域中的任意一个控制区域检测到控制区域参数的配置变更信令之后，该方法还包括：结束波束恢复过程。
示例性的，发送端(终端)在所述M个控制区域中的任意一个控制区域检测到控制区域参数的配置变更信令之后，可以结束波束恢复过程。
可选的，在所述M个控制区域中的任意一个控制区域检测到控制区域参数的配置变更信令之后，该方法还包括以下至少之一：
重置用于波束恢复过程的定时器和/或计数器；

实施例六
图6为本公开实施例六提供的一种波束恢复异常处理方法的流程示意图，如图6所示，本实施例六提供一种波束恢复异常处理方法，应用于发送端(终端)，该方法包括：
步骤S601、上报波束恢复的指示信息；
示例性的，发送端(终端)对波束进行监测，该监测过程主要是通过参考信号进行波束失效(beam failure)的判断，如果在需要进行波束恢复时，发送端(终端)会上报用于波束恢复的指示信息，该指示信息例如可以是发送端(终端)的指示信息、波束指示信息等。
步骤S602、检测M个控制区域的一个或者多个控制区域，其中，M≥1，M为整数。
示例性的，发送端(终端)在上报所述指示信息之后，开始检测M个控制区域，其中，M≥1，M为整数，可以根据波束恢复的实际情况配置M个控制区域，例如：根据波束恢复的三个过程，配置一个波束恢复前的第一控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；配置一个在波束恢复时的第二控制区域会，第二控制区域一般也是基站通过高层信令配置，为波束恢复期间需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；配置一个在波束恢复后的第三控制区域，第三控制区域一般也是基站通过高层信令配置，为波束恢复后需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的；但并不以此为限。
可选的，所述M个控制区域中，包括：至少一个第一控制区域或至少一个第二控制区域，其中，所述第一控制区域为在上报波束恢复的指示信息之前需要检测的控制区域，所述第二控制区域为用于接收波束恢复响应的控制区域。
示例性的，发送端(终端)检测这M个控制区域中，至少一个第一控制区域或至少一个第二控制区域，可以是第一控制区域或第二控制区域，其中，该第一控制区域为上报波束恢复的指示信息之前需要检测的控制区域，该第一控制区域一般是接收端(基站)通过高层信令配置的，正常通信期间需要检测的CORESET(s)(控制资源集合)，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，多个CORESETs包含的资源可以存在重叠；第二控制区域为接收波束恢复响应的控制区域，第二控制区域一般也是基站通过高层信令配置，为波束恢复期间需要检测的CORESETs，可以为一个或者多个，每个CORESET内包含的资源可以在时频上不连续的，但并不以此为限。
步骤S603、当存在以下配置变更之一时，中断所述波束恢复：
所述波束监测中的被监测的对象被配置变更；
所述波束选择的参考信号配置变更；
所述M个控制区域中的任意一个控制区域配置变更；
所述波束上报的资源配置变更。
示例性的，发送端(终端)进行波束失效判断，一般根据被监测参考信号的质量测量结果与质量门限进行比较，若不满足质量门限要求，则判断结果波束失效，需要发起波束恢复，后续步骤包括发送端(终端)进行波束选择，发送端(终端)进行波束指示信息上报，发送端(终端)进行控制信令检测，但在此过程中由于发送端(终端)和接收端(基站)对于目前的链路状态及参数的理解可能出现一些不对称，因此，可能会出现一些异常状况，需要中断波束恢复，这里说的中断波束恢复包括以下至少之一：
1、波束监测中的被监测的对象被配置变更；
2、波束选择的参考信号配置变更；
3、M个控制区域中的任意一个控制区域配置变更，例如可以是第一控制区域，或者第二控制区域。
4、波束上报的资源配置变更。
可选的，在所述上报波束恢复的指示信息之前，还包括：
检测所述第一控制区域和/或第二控制区域；

可选的，中断所述波束恢复包括以下至少之一：
终止检测第二控制区域或第二控制区域失效；
终止当前波束选择；
终止当前波束上报；
重置用于波束恢复过程的定时器和/或计数器。
可选的，该方法还包括：
在中断所述波束恢复之后，重新/接续波束恢复；

重新进行波束失效判断；
重新进行波束选择；
重新进行波束上报；
在重新配置的第二控制区域进行检测；
重启用于波束恢复过程的定时器和/或计数器。
示例性的，例如：判断波束失效后，还没有上报新的波束之前，发送端(终端)需要对正常通信使用的第一控制区域进行检测。此时有可能收到，波束监测中的被监测的对象配置变更信息。如果收到该信息，说明之前监控的波束测量到的监控结果没有意义，应该 中断波束恢复，发送端(终端)应该按照新的配置重新进行波束失效判断，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
判断波束失效后，上报新波束之后，发送端(终端)仍然需要对正常通信使用的第一控制区域进行检测，此时，也有可能收到波束监测中的被监测的对象配置变更信息。如果收到该信息，波束恢复中断，发送端(终端)应该重新进行波束失效判断，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
判断波束失效后，上报新波束之后，发送端(终端)需要对用于波束恢复第二控制区域进行检测，此时，有可能收到波束监测中的被监测的对象配置变更信息，如果收到该信息，发送端(终端)应该重新进行波束失效判断，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
这里的波束监测对象变更有两种情况，一种是显式的方式，直接变更需要监测的参考信号，还有一种情况是变更第一控制区域的发送波束。
判断波束失效后，发送端(终端)进行新波束选择，在选到新的波束并上报之前，发送端(终端)需要对正常通信使用的第一控制区域进行检测，此时，有可能收到波束选择的参考信号配置变更的信息，如果收到该信息，发送端(终端)应该中断当前波束恢复过程，终止当前波束选择，放弃当前波束选择结果，重新进行波束选择，发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
波束指示信息开始上报后，发送端(终端)需要对正常通信使用的第一控制区域进行检测，此时，有可能收到波束选择的参考信号配置变更的信息。如果收到该信息，发送端(终端)应该终止上报，重新进行波束选择并上报，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
波束指示信息开始上报后，发送端(终端)需要对用于波束恢复的第二控制区域进行检测，此时，有可能收到波束选择的参考信号配置变更的信息。如果收到该信息，发送端(终端)应该终止上报，重新进行波束选择并上报，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
波束指示信息开始上报后，发送端(终端)需要对正常通信使用的第一控制区域进行检测，此时，有可能收到用于波束上报上行资源配置变更的信息。如果收到该信息，发送端(终端)应该终止当前上报并按照该配置进行上报，并且发送端(终端)可以重置波束恢复过程的定时器和/或计数器。
波束指示信息上报后，发送端(终端)需要对正常通信使用的第一控制区域和第二控制区域进行检测，此时，有可能收到第二控制区域配置变更的信息。如果收到该信息，发送端(终端)应该中断在当前第二控制区域的检测，切换至重新配置的第二控制区域检测。
