本发明涉及无线通信领域，更具体地，涉及一种测量信号的传输方法及装置。
背景技术
现有无线通信系统的无线资源管理通常采用基于下行测量信号的测量方式，即基站发送下行测量信号，如参考信号RS(Reference Signal)，终端设备测量该基站发送的参考信号的RSRP(Reference Signal Received Power，参考信号接收功率)/RSRQ(Reference Signal Received Quality，参考信号接收质量)等参数，并将测量结果上报给基站，由基站根据测量结果来决定终端设备的切换和移动。
为了减小无线资源管理对网络发送频繁的、固定的下行测量信号的依赖，提升系统效率，考虑引入基于上行测量信号的测量方法，即终端设备发送上行测量信号，由终端设备关联的网络设备，如基站或TRP(transmission reception point，传输接收点)以及相邻基站或TRP对该终端设备发送的上行信号进行测量，并对各基站或TRP的测量结果进行比较和判决，以决定终端设备切换到合适的小区进行服务。
为了满足移动通信系统的大容量及高速率的传输需求，引入大于6GHz的高频频段进行通信，以利用其大带宽、高速率的传输特性，由于高频通信的高路损，需采用窄波束来保证传播距离和高波束增益，因此，上行测量信号或下行测量信号也采用方向性的窄波束传输，由于高频通信中波束数量较多，会产生比较大的测量开销。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。

图7是本发明又一实施例测量信号发送装置示意图。
具体实施方式
本发明实施例可以用于各种技术的的无线网络。无线接入网络设备在不同的系统中可包括不同的网元。例如，LTE(Long Term Evolution)、LTE-A(LTE Advanced)和5G NR(New Radio)中无线接入网络的网元包括eNB(eNodeB，演进型基站)、TRP(transmission reception point)等，WLAN(wireless local area network)/Wi-Fi的网元包括接入点(Access Point，AP)等。其它无线网络也可以使用与本发明实施例类似的方案，只是基站系统中的相关模块可能有所不同，本发明实施例并不限定。
还应理解，在本发明实施例中，终端设备包括但不限于用户设备(UE，User Equipment)、移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(RAN，Radio Access Network)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在高频通信过程中需采用窄波束来保证传播距离和高波束增益，并进行波束对准来保证通信质量，因而网络设备与不同终端设备在通信的过程中，会在不同的波束对上进行，网络设备通过发送波束(TX beam)发送测量信号，终端设备通过相应的接收波束(TX beam)接收该测量信号；同样终端设备通过发送波束(TX beam)发送测量信号，网络设备通过相应的接收波束(TX beam)接收该测量信号。
在下一代无线通信系统中，即5G通信系统，也称为NR(New Radio)系统，为了减小无线资源管理对网络发送频繁的、固定的下行参考信号的依赖，提升系统效率，考虑引入基于上行测量信号的测量方法，即终端设备发送上行测量信号，由终端设备关联的基站或传输接收点TRP(transmission reception point)以及相邻基站或TRP对该终端设备发送的上行信号进行测量，并对各基站或TRP的测量结果进行比较和判决，以决定终端设备切换到合适的小区进行服务。5G系统中，基站可以包括一个或多个TRP，小区可以为一个或多个TRP形成的覆盖范围。使用上行信号测量使得网络可以对终端设备进行跟踪，不仅可以使网络跟踪到终端设备当前所处位置，还可以知道哪个TRP或基站可以提供当前最好的传输。
为了提升网络效率，在无线资源管理方面提供更好的灵活性。本发明实施例提出了在高频通信系统场景下上行/下行测量信号混合的发送方式，以提高测量的准确性，节省测量信号开销。
本实施例一给出了一种高频系统中，网络设备和终端设备采用上行信号来辅助下行测 量信号的发送方法。终端设备在多个上行发送波束上发送上行测量信号，例如，可以是上行SRS(sounding reference signal，探测参考信号)，上行跟踪信号(Tracking signal)，也可以是其它测量信号；网络设备根据接收到的上行测量信号的信号强度，确定最优发送波束的波束方向，并根据所述波束方向采用相应的下行波束进行下行测量信号的发送。
以下以网络设备是基站为例进行说明，参考图1，该下行测量信号的发送方法包括：
101、终端设备分别在多个发送波束上发送上行测量信号；
终端设备可以以波束扫描的方式分别在不同上行发送波束上发送上行测量信号，例如，上行测量信号可以为SRS，Tracking signal，也可以是其它测量信号；基站可以接收到一个或多个波束上的上行测量信号，通常为多个。
参考图4，终端设备可以在一个UL SRS burst中针对多个上行发送波束(TX beam)发送上行测量信号，其中一个UL SRS burst包括多个UL SRS block，每个UL SRS block用于在一个发送波束上发送的上行测量信号，每个UL SRS block占一个或多个symbol。一个UL SRS burst可以轮询完终端设备各个发送波束，也可以轮询部分发送波束。
102、基站接收到多个发送波束上发送上行测量信号，检测各个波束的上行测量信号的信号强度，确定最优的发送波束的波束方向。
例如：基站接收到多个SRS block的SRS信号，检测各个SRS信号的信号强度信息，该信号强度信息可以是基于RSRP/RSRQ值，也可以是基于CQI值，也可以采用其它类型检测值，如RI、PMI。由于每个SRS block对应一个发送波束，TRP可以根据接收到的每个SRS block对应的SRS的信号强度信息，确定信号最强的发送波束的波束方向，信号最强的发送波束即最优发送波束。
另外，也可以设定阈值，将信号强度高于阈值的波束均作为最优发送波束，此时最优发送波束可以为一个或多个。
由于基站是采用对应接收波束接收终端设备发送的上行测量信号，终端最优的发送波束对应相应的基站最优的接收波束。
103、基站根据最优发送波束的波束方向采用相应的下行波束向所述终端设备发送下行测量信号。
基站根据最优的发送波束的波束方向，针对该终端设备，采用相应的下行发送波束发送下行测量信号。该下行测量信号可以是针对该终端设备的CSI-RS(channel state information-reference signal，信道状态信息参考信号)，SS(Synchronization Signal，同步信号)，也可以是针对各个波束的参考信号RS，MRS(measurement reference signal，测量参考信号)，也可以为其它类型参考信号，本发明实施例不限定。
后续，终端设备可以检测基站发送的参考信号，并上报检测结果给基站，基站便可根据终端设备的检测结果进行相应的处理，该流程为现有技术，不再详述。
本实施例二给出了一种高频系统中，网络设备和终端设备采用下行信号来辅助上行测量信号的发送方法。基站在多个下行发送波束上发送下行测量信号，可以是下行MRS，也可以是其它测量信号；终端设备根据接收到的下行测量信号的信号强度，确定最优发送波束的波束方向，并根据所述波束方向采用相应的上行发送波束进行上行测量信号的发送。
参考图2，该上行测量信号的发送方法包括：
201，基站在多个发送波束上发送的下行测量信号；
基站可以采用波束扫描的方式在多个下行发送波束上发送下行测量信号，如果有多个基站，则可以分别以波束扫描的方式发送，下行测量信号可以为测量参考信号MRS；也可以为上述实施例中提到的其它类型的测量信号。
202，终端设备接收到的下行测量信号，检测所述下行测量信号的信号强度信息，确定最优发送波束的波束方向；
例如：终端设备测量下行测量信号的信号强度，将信号强度最强的发送波束作为最优发送波束，例如可以测量各个波束的RSRP或RSRQ，确定最优波束；进一步的可以反馈最佳的下行发送波束给基站。
另外，也可以设定阈值，将信号强度高于阈值的波束均作为最优发送波束，此时最优发送波束可以为一个或多个。
203、终端设备根据所述最优发送波束的波束方向使用对应的上行发送波束向所述基站发送上行测量信号。
终端设备在最优波束方向采用对应的上行波束发送上行测量信号给基站，上行测量信号可以是上行跟踪信号或上行参考信号。可以采用波束扫描(beam sweeping)的方式发送上行测量信号。
后续，基站可以测量终端设备发送的上行测量信号，然后，基站便可根据测量结果进行相应的处理，该流程为现有技术，不再详述。
除了采用上述确定最优波束的方法，在另一实施方式中，也可以采用确定最优端口的方式；终端设备接收基站发送的下行测量信号后，终端设备也可以测量下行测量信号对应的各个端口，根据得到的端口的测量量(例如可以为RSRP或RSRQ)确定最优端口，如信号最强的端口，然后根据最优端口对应的一个或多个波束方向采用相应的发送波束发送上行测量信号。所述端口为对应测量信号时频资源位置，一个端口可以对应一个或多个发送波束，基站可以预先将需要测量的端口号通知终端设备。
另外，也可以设定阈值，将测量量高于阈值的端口均作为最优端口，阈值可以预先由基站通知终端设备。
实施例三给出了一种高频系统中，终端设备和基站采用下行和上行混合的方式来发送无线测量信号的方法，参考图3，该方法包括：
301、基站在多个发送波束上向终端设备发送下行测量信号；
基站可以以波束扫描的方式向在不同方向的下行波束上发送下行测量信号，从而不同位置的终端均可收到；一个终端设备可以接收到一个或多个波束方向的参考信号，通常为多个波束的参考信号。下行测量信号的类型可以参考上述实施例中提到的下行测量信号，不再详述。
302、终端设备检测所述多个发送波束上的下行测量信号的信号强度，并向所述基站反馈检测结果；
终端设备接收到多个波束的下行测量信号，检测各个波束的下行测量信号的信号强度，例如测量各个波束的下行测量信号的RSRP值，也可以采用其它测量参数，如或RSRQ，本实施例不限定；并向基站反馈检测结果。
检测结果为多个波束的下行测量信号的信号强度的平均值或最大值，例如：可以反馈测量的多个波束中最大的RSRP值，也可以反馈多个波束的RSRP的平均值。
在另一个实施例中，也可以将各个波束的RSRP值均反馈给基站，由基站计算RSRP平均值。
如果终端设备只收到一个波束的下行测量信号，只反馈该波束的RSRP值。
303、基站根据所述反馈结果确定所述终端设备进入小区的边界区域，则通知所述终端设备采用上行信号测量方式。
例如：基站检测到所述终端设备反馈的下行测量信号的信号强度小于设定的阈值，则通知所述终端设备采用上行信号测量方式。
基站检测到终端设备的RSRP测量值小于设定的阈值，表示终端设备进入到小区的边界区域；当检测到有多个终端设备的RSRP测量值小于某个阈值，表示该多个终端设备进入到小区的边界区；即基站检测到终端设备移动到小区的边界区域，也就是说，当基站根据终端设备反馈的检测结果确定终端设备进入到小区的边界区域，此时采用下行信号测量方式信令开销较大，则基站通知所述终端设备或多个终端设备采用上行信号测量方式。
另外，除了基站检测到终端设备移动到小区的边界区域，还可以包括其它检测条件，例如，当基站检测到进入到小区的边界区域的终端设备的数量小于设定的阈值时，通知所述终端设备采用上行信号测量方式；例如，阈值可以为邻区基站的数量；即基站检测到终端设备移动到小区的边界区域，并且进入到小区的边界区域的终端设备的数量小于邻区基站的数量时，通知所述终端设备采用上行信号测量方式；终端设备可以为一个或多个。另外，也可以设定其它类型的阈值。
在另一个实施方式中，终端设备接收基站发送的下行测量信号后；所述终端设备检测所述下行测量信号；当所述终端设备检测所述下行测量信号的测量结果小于设定的阈值时，所述终端设备向基站发送上行测量信号。即，由终端设备主动切换上行信号的测量方式，不需要基站通知切换。
在又一个实施方式中，终端设备接收基站发送的下行测量信号；所述终端设备检测所述下行测量信号；当所述终端设备检测所述下行测量信号的测量结果小于设定的阈值时，将测量结果上报网络设备，基站根据测量结果确定采用上行测量信号的测量方式，并通知终端设备采用上行测量信号的测量方式。该方式由基站控制是否采用上行测量，并且只将小于阈值的测量结果上报，节省了网络开销，也避免终端频繁切换测量方式。另外，所述终端设备可以进一步的通知基站采用上行测量信号的测量方式。
除了采用上述实施例中检测多个波束信号强度的方式，在另一实施方式中，可以用测量端口的方式，终端设备接收网络设备发送的下行测量信号后，终端设备可以测量下行测量信号对应的端口，当端口的测量量小于设定的阈值时，所述终端设备向网络设备发送上行测量信号；或者将测量结果上报网络设备，由网络设备根据测量结果确定采用上行测量信号的测量方式，并通知终端设备。
后续，所述终端设备或多个终端设备可以通过一个或多个发送波束向相应的基站发送上行测量信号，上行测量信号可以为SRS或上行跟踪信号，也可以采用其它类型测量信号。基站根据终端设备反馈的上行测量信号进行小区切换判断等相关的流程，不再详述。
在小区边缘区域，由于下行移动性的测量会引发信令开销较大，使用上行信号测量还可以实现终端设备快速的接入，降低下行寻呼消息发送范围和寻呼信令开销，提升网络性能。
本发明上述各个实施方式中，关于终端设备检测下行测量信号的方式，可以针对各个发送波束进行测量，也可以针对各个端口进行测量，测量量均可以采用RSRP或RSRQ，也可以为其它测量量，本发明实施例不限定。
