相关技术中，终端在开机后，会收到由无线接入网络节点，包括不限于新空口(NR，New Radio)基站(gNB，gNodeB)，长期演进(LTE，Long Term Evolution)基站或第三代移动通信技术(3G，3rd-Generation)基站(例如无线网络控制器(RNC，Radio Network Controller)或者/NodeB)发送的同步信道和系统消息。其中，系统消息中携带有包括小区的物理随机接入信道(PRACH，Physical Random Access Channel)配置索引、逻辑根序列初始值、循环移位索引、上下行配置索引等与随机接入有关的参数。终端要接入gNB网络，必须经过小区搜索确定一个服务小区，获取该小区的系统信息并发起 随机接入过程，从而与该小区取得频率同步和符号同步，获取下行帧的起始位置，以及确定小区的物理小区标识(PCI，Physical-layer Cell Identity)。实际应用时，终端不仅需要在开机时进行小区搜索，为了支持移动性(mobility)，终端会在完成随机接入后不停地搜索邻区，从而决定是否进行切换(handover)或小区重选(cell re-selection)。因此，需要始终保持5G小区的公共波束覆盖与用户波束覆盖基本重合，即SSB与CSI-RS基本重合，否则，终端掉话后就无法利用SSB发现小区，也就无法发起对小区的无线资源控制(RRC，Radio Resource Control)重建。然而，上述波束发送机制会导致终端的开销增加。
在部分应用场景下，终端在完成随机接入过程后通常会一直保持在连接态。例如，无人机在升空后，通常只会在一定的范围内移动，无人机在空中会一直保持连接态，以通过连续的用户面传输实现飞行控制和状态监控。此外，在无人机升空后，基站采用专用波束为无人机提供服务。鉴于上述情况，基站并不需要一直发送对空的SSB波束。基于此，本申请实施例中，将第一小区的SSB波束划分为至少两个部分，基站发送第一小区的第一部分SSB波束或者不发送所述第一小区的SSB波束，并在满足设定条件的情况下，激活和/或发送所述第一小区的SSB波束；其中，所述激活和/或发送的SSB波束是已发送SSB波束情况下的其他SSB波束的部分或全部SSB波束，或者是不发送SSB波束情况下的所述第一小区的全部或部分SSB波束。在上述方案中，基站不需要一直发送第一小区的全部SSB波束，这样相应地减少了终端对SSB波束的测量开销，并且，也能对应减少SSB波束的旁瓣对地面小区的干扰。
下面结合附图及实施例对本申请再作进一步详细的描述。
本申请实施例提供了一种波束发送方法，应用于基站，如图1所示，该方法包括：
步骤101：发送第一小区的第一部分SSB波束或者不发送所述第一小区的SSB波束。
其中，第一小区的SSB波束划分为至少两个部分。
这里，基站将第一小区的SSB波束划分为至少两个部分，每个部分可以仅包括一个SSB波束，也可以包括多个SSB波束。比如，在实际应用时，对于无人机等终端，基站首先发送第一小区的m套SSB波束，这m套SSB波束是用于小区的地面覆盖的，以使终端在地面的时候可以通过随机接入流程接入第一小区，此后，比如，无人机终端起飞进入一定高度后，基站通过专用波束为终端提供服务，基站不发送用于空间覆盖的n套SSB波束中除所述m套SSB波束之外的公共波束，或者仅发送用于空间覆盖的所述n套SSB波束中除所述m套SSB波束之外的部分的公共波束，也即基站仅发送第一小区的第一部分SSB波束，或者不发送第一小区的SSB波束。
需要说明的是，将第一小区的所有SSB波束分为至少两个部分，第一小区的第一部分SSB波束指的是所述至少两个部分的SSB波束中的其中一部分SSB波束，“第一部分”中的“第一”不用于描述SSB波束的特定顺序或先后 次序。
在本申请实施例中，终端可以基于SSB波束实现小区搜索、小区发现、小区选择和/或小区重选。
步骤102：在满足设定条件的情况下，或者，在符合设定的时间信息和/或频域信息的情况下，激活和/或发送所述第一小区的SSB波束；所述激活和/或发送的SSB波束是已发送SSB波束情况下的其他SSB波束的部分或全部SSB波束，或者是不发送SSB波束情况下的所述第一小区的全部或部分SSB波束。
其中，第一小区的SSB波束划分为至少两个部分；所述设定的时间信息和/或频域信息由网络提前通过信令配置。
在基站发送第一小区的第一部分SSB波束或者不发送第一小区的SSB波束的情况下，当满足设定条件时，或者，在符合网络提前通过信令配置的时间信息和/或频域信息的情况下，基站激活和/或发送第一小区的全部SSB波束，或者，基站激活和/或发送第一小区的部分SSB波束，这里，基站激活和/或发送的第一小区的部分SSB波束可以包括上述第一部分SSB波束，也可以不包括上述第一部分SSB波束，或者可以包括上述第一部分SSB波束中的部分SSB波束。
其中，所述设定的时间信息包括部分SSB激活/或发送的周期，每个周期的持续时间，SSB波束发送占用的具体时隙和/或时间符号；和/或，所述设定的时间信息包括全部SSB波束激活/或发送的周期，每个周期的持续时间，SSB波束发送占用的具体时隙和/或时间符号；所述设定的频域信息包括部分SSB波束激活/或发送占用的PRB位置，PRB个数和/或子载波间隔。
设定条件表征存在发送除第一部分SSB波束之外第一小区的其他SSB波束的需求，具体的满足设定条件的情况将在下文实施例中进行详细说明。基于上述方案，在基站的波束发送过程中，不需要时刻保持全部SSB波束的发送，对于终端来说，可以相应地减少测量开销，并且这样的做法也可以对应减少SSB波束的旁瓣对地面小区的干扰。
比如，在实际应用时，对于无人机等终端，在满足设定条件的情况下，激活和/或发送所述第一小区的SSB波束，即，在满足设定条件的情况下，基站激活和/或发送用于空间覆盖的所述n套SSB波束中除所述m套SSB波束之外的公共波束。
在一实施例中，所述发送第一小区的第一部分SSB波束，包括：
发送m套SSB波束。
其中，所述m套SSB波束覆盖所述第一小区的部分区域；或者，所述m套SSB波束为所述第一小区的n套SSB波束中的m套SSB波束；m大于或者等于1，且m小于n；n大于1。
其中，上述m套SSB波束和上述n套SSB波束中除所述m套SSB波束之外的SSB波束是同步信道信息是相同的，或者不同的。
作为一种实现方式，参照图2，第一小区对应SSB 1～SSB 8这八个SSB 波束，每个SSB波束可以理解为一套SSB波束，图2示例中，将SSB 5～SSB 7这三个SSB波束作为常态的SSB波束，也即将SSB 5～SSB 7视为第一部分的SSB波束，时刻保持SSB 5～SSB 7的发送。SSB 5～SSB 7作为常态的SSB波束，对应的配置信息通过系统消息中广播的ssb-PositionsInBurst的信息进行周期性发送，终端可以通过SSB 5～SSB 7接入第一小区。在第一小区对应的八个SSB波束中，SSB 1～SSB 4这四个SSB波束作为对空的SSB波束，并不需要一直发送，在满足设定条件的情况下，基站激活和/或发送SSB 1～SSB 4中的全部或部分SSB波束。
作为另一种实现方式，参照图3，第一小区对应SSB 1～SSB 8这八个SSB波束，图3示例中，将这八个SSB波束分为两部分，在图示发射板31处于位置1，即发射板朝下的情况下，基站发送SSB 5～SSB 8，在发射板31处于位置2，即发射板朝上的情况下，基站发送SSB 1～SSB 4。这样，基站通过调整发射板与地平线的角度，来实现不同部分SSB波束的发送。实际应用时，如果基站中配置有多块发射板，那么基站可以同时发送SSB 1～SSB 8，如果基站中仅配置有一块发射板，那么在同一时刻，基站只能同时发送SSB 1～SSB 4或者同时发送SSB 5～SSB 8。基站可以通过系统消息广播两组ssb-PositionsInBurst信息，ssb-PositionsInBurst 1对应SSB 1～SSB 4的配置信息，ssb-PositionsInBurst 2对应SSB 5～SSB 8的配置信息。
在一实施例中，在所述发送m套SSB波束之后，所述激活和/或发送所述第一小区的SSB波束，包括：
激活和/或发送所述n套SSB波束中除所述m套SSB波束之外的全部或部分SSB波束；或者，
停止所述m套SSB波束的发送，并激活和/或发送所述n套SSB波束中除所述m套SSB波束之外的部分或全部SSB波束。
这里，基站首先发送第一部分的m套SSB波束，并且在满足设定条件的情况下，激活和/或发送其余部分的n-m套SSB波束。并且，在激活和/或发送其余部分的n-m套SSB波束的情况下，基站可以选择继续发送第一部分的m套SSB波束，或者选择停止发送第一部分的m套SSB波束，或者选择继续发送第一部分的m套SSB波束中的部分SSB波束。
在一实施例中，在所述发送第一小区的第一部分SSB波束或者不发送所述第一小区的SSB波束之前，所述方法还包括：
通过系统消息或者RRC信令为终端配置所述第一小区的SSB波束。
实际应用时，基站可以仅将当前发送的SSB波束的发送状态告知终端，也可以将所有SSB波束的发送状态告知终端。针对后一种实现方式，在一实施例中，所述通过系统消息或者RRC信令为终端配置所述第一小区的SSB波束，包括：
通过系统消息或者RRC信令指示所述至少两个部分的SSB波束中每个部分的SSB波束的发送状态。
这里，基站可以将第一小区每部分的SSB波束的发送状态告知终端，这 样，终端基于基站发送的系统消息或者RRC信令，可以确定出哪些SSB波束被激活且处于发送状态，并根据处于发送状态的SSB波束的配置信息完成SSB波束测量。结合图3示例，在终端接入第一小区后，基站通过发送系统消息或者RRC信令，告知终端SSB 1～SSB 4处于未激活状态，SSB 5～SSB 8处于激活状态，
以下对满足设定条件的情况进行说明：
在一实施例中，所述在满足设定条件的情况下，激活和/或发送所述第一小区的SSB波束，包括：
在接收到终端上报的第一测量事件的情况下，激活和/或发送所述第一小区的SSB波束。
其中，所述第一测量事件表征终端没有可用的专用波束。
这里，将基站接收到终端上报的第一测量事件视为满足设定条件的情况，这里，第一测量事件在终端检测到没有可用的专用波束的情况下上报。
具体地，所述第一测量事件在满足以下条件时上报：
终端对任一专用波束的测量结果低于第一设定门限；和/或，
终端进行数据传输的BLER高于第二设定门限。
其中，终端进行数据传输的BLER高于第二设定门限，可以理解为此时终端的通信状况接近无线链路失败(RLF，Radio Link Failure)的触发条件。
在一实施例中，在满足设定条件的情况下，激活和/或发送所述第一小区的SSB波束，还可以包括：
基站对终端的上行信号进行测量或者对终端在上行发送的数据包的速率或流量进行检测，当满足第二测量事件的情况下，激活和/或发送所述第一小区的SSB波束。
其中，所述第二测量事件表征终端没有可用的专用波束。
这里，将基站对终端的上行信号进行测量或者对终端在上行发送的数据包的速率或流量进行检测而满足第二测量事件视为满足设定条件的情况，这里，第二测量事件在终端检测到没有可用的专用波束的情况下上报。
实际应用时，基站为终端配置第一测量事件上报的触发条件，包括终端对当前使用的及其他可用的专用波束的测量结果均低于第一设定门限，和/或终端进行数据传输的BLER高于第二设定门限。上述第一测量事件上报的触发条件均表征终端没有可用的专用波束，或者说专用波束无法保障终端的最低通信需求，因此，在终端检测到满足第一测量事件上报的触发条件的情况下，向基站上报第一测量事件，从而触发基站激活和/或发送第一小区的SSB波束。
实际应用时，基站为终端配置为了检测第二测量事件的触发条件，包括给终端配置为了便于基站检测第二测量事件的上行信号的信息，包括发送的码信息，或者/和发送的资源信息。
在一实施例中，所述激活和/或发送所述第一小区的SSB波束，包括：
根据所述第一测量事件中的第一信息确定激活和/或发送的SSB波束的码 本、方向和发射功率；
所述第一信息包括以下至少一项：
终端对专用波束的测量结果；
终端的高度；
终端和所述基站的站间距；
终端的速度；
第一角度；所述第一角度表征终端与所述基站的连线与地平线的夹角。
实际应用时，终端上报的第一测量事件中包括用于表征第一测量事件的事件标识，还包括上述第一信息中的至少一项，基站根据终端上报的内容，确定出与上述第一信息匹配的SSB波束的码本、方向和发射功率，从而确定出需要激活和/或发送的SSB波束。其中，基站发射SSB波束的方向可以根据第一信息中表征的终端的高度、终端与基站的站间距及终端的速度、第一角度等信息进行调整，基站发射SSB波束的发射功率可以根据第一信息中表征的终端的高度进行调整。例如，当终端为无人机时，在图2示例中，基站激活第一小区的SSB 1～SSB 4，以实现对空SSB波束的发送，向无人机所在位置的方向发送SSB波束，从而为无人机的空中飞行提供通信保障。
在一实施例中，所述激活和/或发送所述第一小区的SSB波束时，所述方法还包括：
向所述终端发送第二信息。
其中，所述第二信息表征激活和/或发送的SSB波束对应的配置信息。
在一实施例中，所述第二信息包括以下至少之一：
SSB波束的索引；
SSB波束对应的DMRS信息；
SSB波束对应的剩余最小系统信息。
在一实施例中，所述第二信息通过PDCCH的动态DCI发送。
这里，基站使用PDCCH的动态DCI调试信息向终端指示基站激活和/或发送的SSB波束的相关配置，以使终端可以根据基站发送的配置，对对应的SSB波束启动测量。
实际应用时，在基站激活和/或发送了新的SSB波束后，当终端又发现了可用的专用波束的情况下，终端可以通知基站，以使基站停止对应全部或部分SSB波束的发送，这样，在保障终端通信的情况下，可以及时地降低终端的测量开销。基于此，在一实施例中，所述方法还包括：
接收所述终端发送的第三信息；所述第三信息在所述终端测量到可用的专用波束的情况下发送；
基于所述第三信息停止发送所述第一小区的全部或部分SSB波束。
这里，基站基于所述第三信息停止发送所述第一小区的全部或部分SSB波束，可以理解为基站仅继续发送第一小区的第一部分SSB波束或者不发送第一小区的SSB波束，也可以是基站发送第一小区的其他部分的SSB波束。
在一实施例中，终端可以通过RAR消息发送上述第三信息。
在一实施例中，所述方法还包括：
根据以下之一确定所述至少两个部分的SSB波束中每个部分的SSB波束是否被发送：
高度大于设定高度的终端的数量；
终端的QoS需求。
这里，基站根据上述信息来提前选择激活的SSB波束。例如，当接入第一小区的无人机中高度大于设定高度的终端较多时，可以激活图3示例中的SSB 1～SSB 4，为这部分无人机在空中的通信提供保障。又例如，对于QoS需求较高的无人机来说，当无人机接入第一小区并处于飞行状态时，除了为无人机提供专用波束，还可以激活图3示例中的SSB 1～SSB 4，以进一步保障无人机在空中的QoS需求。
在一实施例中，所述方法还包括：
根据终端的设定路线确定所述至少两个部分的SSB波束中每个部分的SSB波束是否被发送，和/或确定被发送的SSB波束的激活时间点。
实际应用时，基站除了可以根据终端上报的第一测量事件中的第一信息确定需要激活和/或发送的SSB波束，以及可以根据高度大于设定高度的终端的数量和/或终端的QoS需求确定需要激活和/或发送的SSB波束，还可以根据终端的设定路线来确定需要激活和/或发送的SSB波束。例如，对于无人机来说，存在预先制定设定飞行路线的应用场景，基于设定路线涉及的位置、高度等信息，基站可以确定激活和/或发送第一小区的哪部分SSB波束，进一步地，根据无人机的飞行路线规划，基站还可以确定对应的SSB波束的激活时间点，这样，在激活时间点到达时，无人机即将飞入或者飞入飞行路线上的某一区域，此时，基站再将对应的SSB波束激活，从而避免因提前激活SSB波束而带来的小区干扰。
相应地，本申请实施例还提供了一种波束测量方法，应用于终端，如图4所示，该方法包括：
步骤401：在接入第一小区并进入连接态后，不进行SSB波束的测量，只进行专用波束的监测和/或测量。
实际应用时，对于无人机等终端，基站首先发送第一小区的全部SSB波束，终端通过随机接入流程接入第一小区，此后，基站通过专用波束为终端提供服务，基站不再发送公共波束或者仅发送部分公共波束，也即基站仅发送第一小区的第一部分SSB波束，或者不发送第一小区的SSB波束，对应地，终端接入第一小区并处于连接态后，不进行SSB波束的测量，只进行专用波束的监测和/或测量。
步骤402：在没有可用的专用波束的情况下，向基站上报第一测量事件。
其中，所述第一测量事件用于基站激活和/或发送第一小区的全部或部分SSB波束。
在一实施例中，所述第一测量事件在满足以下条件时上报：
所述终端对任一专用波束的测量结果低于第一设定门限；和/或，
所述终端进行数据传输的BLER高于第二设定门限。
实际应用时，基站事件为终端配置第一测量事件上报的触发条件，包括终端对当前使用的及其他可用的专用波束的测量结果均低于第一设定门限，和/或终端进行数据传输的BLER高于第二设定门限。上述第一测量事件上报的触发条件均表征终端没有可用的专用波束，或者说专用波束无法保障终端的最低通信需求，因此，在终端检测到满足第一测量事件上报的触发条件的情况下，向基站上报第一测量事件，从而触发基站激活和/或发送全部或部分SSB波束。
在一实施例中，所述第一测量事件中包括第一信息；所述第一信息包括以下至少一项：
所述终端对专用波束的测量结果；
所述终端的高度；
所述终端和所述基站的站间距；
所述终端的速度；
第一角度；所述第一角度表征所述终端与所述基站的连线与地平线的夹角。
实际应用时，终端上报的第一测量事件中包括用于表征第一测量事件的事件标识，还包括上述第一信息中的至少一项，基站根据终端上报的内容，确定出与上述第一信息匹配的SSB波束的码本、方向和发射功率，从而确定出需要激活和/或发送的SSB波束。其中，基站发射SSB波束的方向可以根据第一信息中表征的终端的高度、终端与基站的站间距及终端的速度、第一角度等信息进行调整，基站发射SSB波束的发射功率可以根据第一信息中表征的终端的高度进行调整。例如，当终端为无人机时，在图2示例中，基站激活第一小区的SSB 1～SSB 4，以实现对空SSB波束的发送，向无人机所在位置的方向发送SSB波束，从而为无人机的空中飞行提供通信保障。
在一实施例中，所述方法还包括：
接收所述基站发送的第二信息。
其中，所述第二信息表征所述基站激活和/或发送的SSB波束对应的配置信息。
在一实施例中，所述第二信息包括以下至少之一：
SSB波束的索引；
SSB波束对应的DMRS信息；
SSB波束对应的剩余最小系统信息。
在一实施例中，所述第二信息通过PDCCH的DCI发送。
这里，基站使用PDCCH的动态DCI调试信息向终端指示基站激活和/或发送的SSB波束的相关配置，以使终端可以根据基站发送的配置，对对应的SSB波束启动测量。
实际应用时，在基站激活和/或发送了新的SSB波束后，当终端又发现了可用的专用波束的情况下，终端可以通知基站，以使基站停止对应全部或部 分SSB波束的发送，这样，在保障终端通信的情况下，可以及时地降低终端的测量开销。基于此，在一实施例中，所述方法还包括：
在所述终端在测量到可用的专用波束的情况下，向所述基站发送第三信息。
其中，所述基站基于所述第三信息停止发送所述第一小区的全部或部分SSB波束。
在一实施例中，所述第三信息通过RAR消息发送。
在上文终端侧实施例中，基站基于终端主动上报的第一测量事件，激活和/或发送第一小区的全部或部分SSB波束。此外，从上文基站侧实施例中可知，基站可以不通过第一测量事件激活和/或发送第一小区的全部或部分SSB波束，而是根据高度大于设定高度的终端的数量和/或终端的QoS需求来确定需要激活和/或发送第一小区的SSB波束，或者，基站根据终端的设定路线来确定需要激活和/或发送第一小区的SSB波束，并进一步地，可以根据终端的设定路线来确定SSB波束的激活时间点。并且，基站会通过系统消息或者RRC信令向终端指示第一小区每个部分的SSB波束的发送状态，终端基于基站发送的系统消息或者RRC信令，可以确定出哪些SSB波束被激活且处于发送状态，并根据处于发送状态的SSB波束的配置信息完成SSB波束测量。
具体地，终端在确定出哪些SSB波束处于发送状态后，根据这部分SSB波束的配置信息，可以确定对应的GAP的格式，确定PRACH和前导码的选择集合，和/或切到正在发送的SSB波束对应的BWP的资源块上。
本申请实施中，第一小区的SSB波束划分为至少两个部分，基站发送第一小区的第一部分SSB波束或者不发送所述第一小区的SSB波束，并在满足设定条件的情况下，激活和/或发送所述第一小区的SSB波束；其中，所述激活和/或发送的SSB波束是已发送SSB波束情况下的其他SSB波束的部分或全部SSB波束，或者是不发送SSB波束情况下的所述第一小区的全部或部分SSB波束。在上述方案中，基站不需要一直发送第一小区的全部SSB波束，这样相应地减少了终端对SSB波束的测量开销，并且，也能对应减少SSB波束的旁瓣对地面小区的干扰。
