本申请主张在2017年4月26日在中国提交的中国专利申请号No.201710283017.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域，尤其涉及一种信号处理方法及装置。
背景技术
在NR(New Radio，新空口)系统，支持半持续(Semi-persistent)CSI-RS(信道状态信息测量导频)和非周期(Aperiodic)CSI-RS的发送。
以半持续CSI-RS触发为例，基站发送半持续CSI-RS可以通过MAC(Media Access Control，介质访问控制)信令或物理层信令触发。终端收到触发信令后可以测量半持续CSI-RS，并进行CSI(Channel State Information，信道状态信息)的反馈。基站可以用发送半持续CSI-RS的触发信令，触发终端反馈半持续CSI或者采用另一个触发信令来触发终端反馈半持续CSI。
在NR系统中，半持续CSI-RS触发和非周期CSI-RS触发，主要用于触发终端进行半持续CSI反馈和非周期CSI反馈。在半持续触发CSI-RS和非周期的发送的过程中，终端根据基站的指示对每个基站的CSI-RS进行反馈，从而造成了资源的浪费。

在下面的实施例中，描述一下基站触发半持续CSI-RS发送和终端反馈的方法，具体过程如下：
基站发送触发发送半持续CSI-RS命令。其中，利用该命令指示终端开始反馈信息。在发送触发发送半持续CSI-RS命令之后，基站发送半持续CSI-RS。如图5所示，基站在发送了该命令后，发送N次半持续CSI-RS，N为大于或等于2的整数。基站每次发送的半持续CSI-RS至少占用一个时间单元，两次发送的半持续CSI-RS之间的间隔为大于或等于0个时间单元。
基站在每次发送半持续CSI-RS时，可以采用相同的预编码(相同波束方向上发送)，或者可以采用不同预编码(不同波束方向上发送)。基站是采用的相同预编码或是采用的不同预编码这一信息，可以在触发发送半持续 CSI-RS命令中一起发送给终端，或单独发送给终端，或与其他信令一起发送给终端，或者通过高层信令配置给终端，或者通过和终端预先预定的方式设置。如果基站只采用了一种预编码方式，那么不需要通知终端。
之后，基站发送触发停止半持续CSI-RS命令，停止发送半持续CSI-RS，并指示终端停止反馈。
终端在收到每个非周期CSI-RS后，分别进行测量。
根据基站发送的N次半持续CSI-RS是否采用相同的预编码，终端可有不同的处理方式：
如果基站发送的N次半持续CSI-RS采用相同的预编码(相同波束方向上发送，终端采用不同的接收波束接收半持续CSI-RS，也就是训练终端的接收波束。终端根据接收信号水平确定最好的一个接收波束或多个接收波束，在此称为目标接收波束。终端可以向基站不反馈任何信息，或者根据触发停止半持续CSI-RS命令一次性反馈目标接收波束的信息，如波束标识等。
如果基站发送的N次半持续CSI-RS采用不同的预编码(不同波束方向上发送)，终端接收半持续CSI-RS，并根据接收信号水平确定最好的目标接收波束，确定所述目标接收波束对应的目标发送波束。终端根据触发停止半持续CSI-RS命令，向基站一次性反馈目标发送波束的相关信息(如波束标识)或者所述目标接收波束接收的CSI-RS的标识。
基站收到终端的反馈信息后，基站根据反馈信息进行下行数据传输。例如，终端反馈了一个最佳基站发送波束(波束标识或CSI-RS标识)，那么后续发送数据时，基站在该发送波束方向上对该终端发送数据从而，提高传输性能。
在下面的实施例中，描述一下基站触触发非周期CSI-RS发送和终端反馈的方法。
基站发送触发发送非周期CSI-RS命令。其中，利用该命令指示终端开始反馈信息。
基站发送N(N为大于或等于2的整数)个非周期CSI-RS。如图6所示，基站触发N个CSI-RS资源。每个CSI-RS至少占用一个时间单元。两个CSI-RS之间间隔为大于等于0个时间单元。基站在每次发送CSI-RS资源时，可以采 用相同的预编码(相同波束方向上发送)，或者可以采用不同的预编码(不同波束方向上发送)。基站是采用的相同预编码信令或是采用的不同预编码信令这一信息，可以在触发发送非周期CSI-RS命令中一起发送给终端，或单独发送给终端，或与其他信令一起发送给终端，或者通过高层信令配置给终端，或者通过和终端预先预定的方式设置。如果基站只采用了一种预编码方式，那么不需要通知终端。
终端在收到每个非周期CSI-RS后，分别进行测量。
根据基站发送的非周期CSI-RS是否采用相同的预编码，终端可有不同的处理方式：
如果基站发送的N个非周期CSI-RS资源采用相同的预编码(相同波束方向上发送)，终端采用不同的接收波束接收非周期CSI-RS，也就是训练终端的接收波束。终端根据接收信号水平确定最佳的一个或多个接收波束，在此称为目标接收波束。终端可以向基站不反馈任何信息或者一次性反馈目标接收波束信息。
如果基站发送的N个非周期CSI-RS资源采用不同的预编码(不同波束方向上发送)，终端接收非周期CSI-RS，并根据接收信号水平确定最好的目标接收波束，确定所述目标接收波束对应的目标发送波束。终端根据触发停止半持续CSI-RS命令，向基站一次性反馈目标发送波束的相关信息(如波束标识)或者所述目标接收波束接收的CSI-RS的标识。
基站收到终端的反馈信息后，基站根据反馈信息进行下行数据传输。例如，终端反馈了一个最佳基站发送波束(波束标识或CSI-RS标识)，那么后续发送数据时，基站在该发送波束方向上对该终端发送数据从而，提高传输性能。
在下面的实施例中，描述一下终端发送半持续SRS和基站反馈的方法。
基站向终端发送触发半持续SRS命令。同时，基站通知终端采用相同的预编码(波束)还是不同的预编码(波束)发送半持续SRS。是采用相同预编码信令或是采用的不同预编码信令，基站可以在触发半持续SRS的命令中一起发送给终端，或单独发送给终端，或与其他信令一起发送给终端，或者通过高层信令配置给终端，或者基站和终端预先默认。基站向终端发送停止 半持续SRS发送命令后，终端根据收到的命令不再发送半持续SRS。
终端接收到触发半持续SRS的命令之后发送半持续SRS。如图7所示，终端向基站发送M个半持续SRS，M为大于或等于2的整数。两次发送SRS之间间隔为大于等于0个时间单元。
根据基站的指示，终端可采用相同的预编码(波束)发送半持续SRS，或者采用不同预编码(波束)发送半持续SRS。
基站接收并测量半持续SRS。在此，根据终端发送半持续SRS的方式不同，基站可有不同的处理方式：
如果终端采用相同的预编码(波束)发送半持续SRS，基站可以不反馈任何信息；如果终端采用不同预编码(波束)发送半持续SRS，基站根据对所述M个半持续SRS的测量结果，确定一个或者多个信号质量最好的目标半持续SRS，并一次性向所述终端反馈所述目标半持续SRS的信息。
在此实施例中，基站还可向终端发送指示信息，以通知所述终端在后续发送上行导频信号时，是否需要改变发送波束。例如，基站可以利用波束标识(beam index)指示终端是否可以改变波束，例如在触发半持续SRS命令中如果包含了波束标识(beam index)，则终端不改变波束，否则可以改变波束。
在下面的实施例中，描述一下终端发送非周期SRS和基站反馈的方法。
基站向终端发送触发非周期SRS命令。同时，基站通知终端采用相同的预编码(波束)还是不同的预编码(波束)发送非周期SRS。是采用相同预编码信令或是采用的不同预编码信令，基站可以在触发非周期SRS的命令中一起发送给终端，或单独发送给终端，或与其他信令一起发送给终端，或者通过高层信令配置给终端，或者基站和终端预先默认。基站向终端发送停止非周期SRS发送命令后，终端根据收到的命令不再发送非周期SRS。
终端接收到触发非周期SRS的命令之后发送非周期SRS。如图8所示，终端向基站发送M个非周期SRS资源，M为大于或等于2的整数。两次发送SRS之间间隔为大于等于0个时间单元。
根据基站的指示，终端可采用相同的预编码(波束)发送非周期SRS，或者采用不同预编码(波束)发送非周期SRS。
基站接收并测量非周期SRS。在此，根据终端发送非周期SRS的方式不同，基站可有不同的处理方式：
如果终端采用相同的预编码(波束)发送非周期SRS，基站可以不反馈任何信息；如果终端采用不同预编码(波束)发送非周期SRS，基站根据对所述M个非周期SRS的测量结果，确定一个或者多个信号质量最好的目标非周期SRS，并一次性向所述终端反馈所述目标非周期SRS的信息。
在此实施例中，基站还可向终端发送指示信息，以通知所述终端在后续发送上行导频信号时，是否需要改变发送波束。例如，基站可以利用波束标识(beam index)指示终端是否可以改变波束，例如在触发非周期SRS命令中如果包含了波束标识(beam index)，则终端不改变波束，否则可以改变波束。
如图9所示，本公开实施例所提供的信号处理装置，包括：
