  • the present application relates to the technical field of communication, and in particular, to a communication method and a communication device.
  • a network device can configure one or more secondary cells (secondary cell, SCell) for a terminal device.
  • the SCell includes two states, which are an activated state and a deactivated state.
  • the network device may deactivate the SCell, and when the amount of data to be sent and received by the terminal device is large, the network may activate the SCell for data sending and receiving. Since the terminal device does not send and receive data on the deactivated SCell, but only performs periodic radio resource management (radio resource management, RRM) measurement, power consumption can be reduced.
  • RRM radio resource management
  • the transition time (ie, the activation time) of a certain SCell to be activated from the deactivated state to the activated state depends on whether the SCell is in a known state or an unknown state when activated. Activation of an SCell in a known state, compared with an SCell in an unknown state, can omit automatic gain control and cell coarse timing search, greatly reducing the activation time.
  • One of the conditions for the activated SCell to be in a known state is that the terminal device has reported the measurement result of the SCell within a period of time before receiving the activation command, so if the network wants the SCell to be activated to be in a known state, the terminal device must be configured periodically Periodically measure and report the measurement results of the SCell, for example, the terminal device reports the measurement result every 3s, but this method of periodic measurement and reporting will increase signaling overhead and power consumption of the terminal device.

  • the network device does not need to associate periodic measurement reports for SCell measurement to determine the state of the first cell, but to determine the state of the first cell based on the first measurement event; SCell does not have a special report from the terminal device By default, it is in a known state, and the activation of SCell meets the requirement of faster activation delay. While improving SCell usability, signaling overhead and power consumption of terminal equipment are reduced.

Description

通信方法及通信装置
本申请要求于2021年12月03日提交中国专利局、申请号为202111470367.6，发明名称为“通信方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及通信装置。
背景技术
在载波聚合(carrier aggregation，CA)中，网络设备可以向终端设备配置一个或多个辅小区(secondary cell，SCell)。考虑到终端设备的功耗，SCell包括两种状态，分别为激活状态和去激活状态。其中，当终端设备的待收发数据量较小时，网络设备可以去激活SCell，当终端设备的待收发数据量较大时，网络可以激活SCell用于数据收发。由于终端设备在去激活的SCell上不收发数据，仅做周期性的无线资源管理(radio resource management，RRM)测量，因此可以降低功耗。一般而言，某个待激活的SCell从去激活状态到激活状态的转换时间(即激活时间)取决于激活时SCell是处于已知状态还是未知状态。已知状态的SCell的激活，相比于未知状态的SCell可以省略自动增益控制和小区粗定时搜索，大大降低激活时间。激活的SCell处于已知状态的条件之一是在终端设备收到激活命令之前的一段时间内上报过SCell的测量结果，因此如果网络希望待激活的SCell处于已知状态，则必须配置终端设备周期性地测量上报SCell的测量结果，例如，终端设备每3s上报一次测量结果，但是这种周期性测量上报的方式会增大信令开销与终端设备功耗。
发明内容
本申请提供了一种通信方法及通信装置，可减少信令开销和终端设备功耗。
第一方面，本申请提供了一种通信方法，该方法适用于终端设备，该方法包括：
接收来自网络设备的测量配置信息，所述测量配置信息中包括测量目标，以及与所述测量目标关联的第一测量事件，所述测量目标为第一小区所在的载波，所述第一测量事件指示所述第一小区发生变化；
基于对所述载波上的所述第一小区进行测量的第一测量结果，确定所述第一测量事件是否被触发；
若所述第一测量事件被触发，则向所述网络设备发送测量报告，所述测量报告指示所述第一测量事件被触发。
在本申请中，通过定义用于指示第一小区发生变化的第一测量事件，可使得当满足第一测量事件的触发条件时，终端设备上报第一测量事件对应的测量报告，相比于周期性测量上报，降低了在激活第一小区之前，测量上报的信令开销以及降低了终端设备功耗，特别是终端设备处于静止或慢速移动状态的情况下可大大减少信令开销和终端设备功耗。

接收来自所述网络设备用于激活所述第一小区的命令；
根据所述第一测量事件的触发结果，确定所述第一小区的状态，其中所述第一小区的状态包括已知状态，未知状态或不可用状态。
在本申请中，基于第一测量事件确定第一小区的状态，以便于后续根据第一小区的不同状态，确定不同的激活方式对第一小区进行激活。例如，当确定终端设备确定第一小区为已知状态时，可基于已知状态对应的激活方式激活第一小区，这样可以省略自动增益控制和小区粗定时搜索的步骤，大大降低激活时间。基于本申请，网络设备不需要为SCell的测量关联周期性的测量上报以确定第一小区的状态，而是基于第一测量事件确定第一小区的状态；SCell在没有终端设备特别上报的情况下默认处于已知状态，SCell的激活满足更快的激活时延要求。在提高SCell可用性的同时降低了信令开销以及终端设备的功耗。

下面对本申请实施例涉及的相关技术特征进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
1、载波聚合(carrier aggregation，CA)
载波聚合是一项增加传输带宽的技术，以满足单用户峰值速率和系统容量提升的要求。CA技术可以将一个基站下的2个或更多的成员载波(component carrier，CC)聚合在一起，实现更大的传输带宽，有效提高了上下行传输速率。UE根据自己的能力大小决定最多可以同时利用几个载波进行上下行传输。
其中，主小区(primary cell，PCell)是UE进行初始连接建立的小区，或进行无线资源控制(radio resource control，RRC)连接重建的小区，或是在切换过程中指定的主小区。PCell负责与UE之间的RRC通信。PCell对应的CC称为主载波(primary component carrier，PCC)。辅小区(secondary cell，SCell)是在初始安全激活流程之后，通过RRC连接重配置添加的，用于提供额外的无线资源。SCell对应的CC称为辅载波(secondary component carrier，SCC)。
在CA中，网络设备可以为终端设备配置一个或多个SCell。考虑到终端设备的功耗，SCell 有激活和去激活两种状态。当终端设备的数据量较大时，网络设备可以激活SCell用于数据收发，当终端设备的数据量较小时，网络设备可以去激活SCell。终端设备在去激活的SCell上不收发数据，仅做周期性的无线资源管理(radio resource management，RRM)测量，因此可以长时间的关闭SCell对应的基带射频资源，降低功耗。但考虑数据业务的突发性，SCell从去激活状态到激活状态的转换时间，即激活时间越短越好。
NR系统中SCell的激活时间取决于激活时SCell是处于已知状态还是未知状态，其中处于已知状态的SCell的激活，相比于处于未知状态的SCell的激活，可以省略自动增益控制和小区粗定时搜索等动作，因此可以大大降低激活时间。
2、已知和未知
已知也可以称为已知状态，未知也可以称为未知状态。
例如，在一种实现中，标准TS38.133中对处于已知状态和未知状态的SCell定义的条件为：
(1)如果满足以下条件，则频带FR1中的SCell是已知的：
①在接收到SCell激活命令之前的max(5*measCycleSCell，5*DRX cycles)时间段内：终端已经发送了一个关于SCell的有效的测量报告，且，根据第9.2和9.3条规定的小区识别条件，测量的同步信号和物理广播信道(physical broadcast channel，PBCH)块(synchronization signal and PBCH block，SSB)仍可检测。
②根据第9.2和9.3条中规定的小区识别条件，在等于max(5*measCycleSCell，5*DRX cycles)的周期内测量的SSB也在小区激活延迟期间保持可检测。
否则，频带FR1中的SCell是未知的。
其中，measCycleSCell表示SCell的测量周期，其可以由网络设备为终端设备配置，一般来说，measCycleSCell的取值可以为160ms,256ms,320ms,512ms,640ms,1024ms或1280ms等，在此不做限制。DRX cycles表示非连续接收(discontinuous reception，DRX)周期，其也可以由网络设备为终端设备配置，一般来说，DRX cycles的取值可以为10ms,20ms,32ms,40ms,60ms,64ms,70ms,80ms,128ms,160ms,256ms,320ms,512ms,640ms,1024ms,1280ms,2048ms,2560ms,5120ms或10240ms等，在此不做限制。
(2)对于频带FR2中的SCell第一次激活，如果满足以下条件，则SCell是已知的：
①在终端接收到物理下行控制信道(physical downlink control channel，PDCCH)传输配置指示(transmission configuration indicator，TCI)、物理下行共享信道(physical downlink shared channel，PDSCH)TCI(适用时)和为信道质量指示(channel quality indicator，CQI)上报的半持续信道状态信息参考信号(channel state information reference signal，CSI-RS)(适用时)中的最后一个激活命令之前的时间段内(UE支持功率等级1则该时间段长度等于4s，UE支持功率等级2/3/4则该时间段长度等于3s)，UE已经发送了关于SCell的有效的L3-RSRP测量报告且该测量报告包含SSB索引。UE在L3-RSRP报告后，不晚于收到MAC-CE命令进行上述TCI激活的时间范围内收到SCell激活命令。
②从L3-RSRP报告到有效CQI上报期间，根据第9.2和9.3条中规定的小区识别条件，已报告的索引对应的SSB保持可检测状态，且上述激活的TCI状态是根据最新报告的SSB索引之一选择的。
否则，频带FR2的第一个SCell是未知的。
在另一种实现中，标准TS38.133中针对切换场景下目标小区处于已知状态的条件定义为：
在(切换的)中断需求中，如果一个小区在最近5秒内满足相关小区识别的需求，则Cell是已知的，否则Cell是未知的。有关小区识别要求见第9.2.5条关于频内切换和第9.3.4条关于频间切换。
3、可检测和不可检测
可检测也可以称为可见，不可检测也可以称作不可见。通常来说，某个小区或者某个发波束(例如某个SSB)可检测即意味着终端设备可以识别该小区或者波束，一般来说，某个小区或者某个发波束可检测的条件是该小区或波束在终端设备处的接收信干噪比和/或接收功率大于等于某一阈值，例如在标准TS38.133中的第9.2.2条中规定了一个同频小区可检测的信干噪比和接收功率的阈值。在实际产品中，终端设备可以根据自身的实现，例如小区识别的算法等确定某个小区或者某个发波束是否可检测，其实现能力可以超过标准TS38.133的规定，例如当某个小区或波束的接收信干噪比低于TS38.133规定的阈值时，终端设备仍然可能认为该小区或波束可检测。不可检测即意味着终端设备无法识别某个小区或者波束。一般来说，某个小区或者某个发波束不可检测的原因是该小区或波束在终端设备处的接收信干噪比和/或接收功率小于某一阈值，例如标准TS38.133中的第9.2.2条中规定的同频小区可检测的信干噪比和接收功率的阈值。
根据上述已知状态条件的定义和可检测条件的定义可知，可检测是已知的必要条件，但可检测未必已知。
4、测量事件(Event)
测量事件包括系统内的A1～A5事件，以及系统间的B1、B2事件等。各个事件的应用场合不同，相应的上报配置要求不同，只有终端设备监测到服务小区和/或邻小区的测量结果符合上报配置要求中设定的门限阈值时，才会向网络设备发送测量报告。
其中，系统内的A1～A5事件分别为：
A1事件：表示服务小区信号质量高于一定门限；
A2事件：表示服务小区信号质量低于一定门限；
A3事件：表示邻小区质量高于服务小区质量，用于同频、异频的基于覆盖的切换；
A4事件：表示邻小区质量高于一定门限，用于基于负荷的切换，可用于负载均衡；
A5事件：表示服务小区质量低于一定门限并且邻小区质量高于一定门限，可用于负载均衡。
其中，系统间的B1、B2事件分别为：
B1事件：表示邻小区质量高于一定门限，用于测量高优先级的异系统小区；
B2事件：服务小区质量低于一定门限，并且邻小区质量高于一定门限，用于相同或较低优先级的异系统小区的测量。
具体地，请参见如下表1和表2：

需要说明的是，相关技术中，SCell已知的条件是基于终端在收到激活命令前的一段时间上报过关于SCell的L3测量结果。如果网络希望待激活的SCell处于已知状态，则必须配置终端设备周期性的测量上报SCell的测量结果，例如，终端设备每3s上报一次测量结果，但是这种周期性进行测量上报的方式会增大信令开销与终端设备功耗。
基于此，本申请提出了一种通信方法，可以在减小信令开销与终端设备功耗的同时，使得终端设备和网络设备可以确定SCell的状态，例如已知状态，未知状态或不可激活状态。
需要说明的是，本申请实施例提供的通信方法可适用于小区的激活场景，例如SCell的激活等；或者，也可以适用于小区切换(handover)场景；或者，也可以适用于小区添加场景等，例如，主辅小区(primary secondary cell，PSCell)的添加过程等，在此不做限制。为方便理解，以下本申请实施例主要以小区的激活场景为例进行示意性说明。
下面对本申请提供的通信方法及通信装置进行详细介绍：
请参见图2，图2是本申请实施例提供的通信方法的一个流程示意图。如图2所示，该通信方法包括如下步骤S201～S203，图2所示的方法执行主体可以为终端设备和/或网络设备，或者，图2所示的方法执行主体也可以为终端设备中的芯片和/或网络设备中的芯片等，或者，图2所示的方法执行主体也可以为其他能执行该方法的设备，在此不做限制。为方便描述，下面将以终端设备为例进行说明。
S201、终端设备接收来自网络设备的测量配置信息。
需要说明的是，在终端设备与网络设备建立了通信连接进入连接态后，网络设备需要为终端设备进行测量配置，使终端设备根据测量配置对小区进行测量，获得小区的测量结果， 为网络无线资源配置提供参考。
具体地，网络设备可以通过发送测量配置信息为终端设备提供测量相关的配置参数。其中，测量配置信息可以包括测量标识、测量目标(measurement object，MO)标识，上报配置标识和具体的配置信息内容等。其中，配置信息内容包括测量目标的信息和上报配置的信息。其中，一个测量标识可以对应一个测量目标和一个上报配置，或多个测量标识可以对应多个测量目标和一个上报配置，即多个测量标识中每个测量标识对应的测量目标不同但对应的上报配置相同，或多个测量标识可以对应一个测量目标和多个上报配置，即多个测量标识中每个测量标识对应的测量目标相同但对应的上报配置不同。测量目标标识对应一个测量目标配置项，测量目标配置项可以包括需要测量的测量频率、测量带宽、频率相关偏移量、小区列表和小区黑名单等。上报配置标识对应一个测量报告配置项，测量报告配置项可以包括需要测量的事件以及相关事件的参数和/或周期性上报的周期等。
为方便理解，以下本申请实施例主要以测量配置信息中包括测量目标，以及与测量目标关联的第一测量事件进行示意性说明。也就是说，网络设备可以向终端设备发送测量配置信息，相应地，终端设备接收来自网络设备的测量配置信息。其中，测量配置信息中包括测量目标，以及与测量目标关联的第一测量事件。
其中，测量目标为第一小区所在的载波，第一测量事件指示第一小区发生变化。需要说明的是，第一小区所在的载波可以是频点等，在此不做限制。第一测量事件可以是定义的新事件，或者，第一测量事件也可以旧事件或已有事件，例如旧事件或已有事件也可以是标准TS38.331的第5.5.4.3条中定义的A2事件等，在此不做限制。
其中，第一小区发生变化包括以下情况中至少一种：第一小区从可检测变为不可检测、第一小区从不可检测变为可检测，或者，第一小区的波束发生变化。也就是说，第一测量事件可以指示第一小区从可检测变为不可检测，和/或，第一测量事件可以指示第一小区从不可检测变为可检测，和/或，第一测量事件可以指示第一小区的波束发生变化等，在此不做限制。
其中，第一小区可以为服务小区，例如，服务小区可以为SCell等，在此不做限制。或者，第一小区也可以是由网络设备指定的非服务小区，即网络设备可以向终端设备发送第二信息，相应地，终端设备接收来自网络设备第二信息。该第二信息用于指示一个或多个非服务小区，终端设备根据网络设备指示的非服务小区的测量结果确定第一测量事件是否被触发。该方法可以用于网络配置某个非服务小区为SCell并在配置时将该SCell的状态配置为‘激活’的情况，即SCell的直接激活。
S202、终端设备基于对载波上的第一小区进行测量的第一测量结果，确定第一测量事件是否被触发。
在一些可行的实施方式中，终端设备可以基于对载波上的第一小区进行测量的第一测量结果，确定第一测量事件是否被触发。也就是说，终端设备可以根据接收到的测量配置信息对该载波上的第一小区进行测量，得到第一测量结果，进而根据第一测量结果确定第一测量事件是否被触发。其中，第一小区的测量结果(例如第一测量结果或第二测量结果等)可以为以下参数中至少一项：参考信号接收功率(reference signal received power，RSRP)，参考信号接收质量(reference signal received quality，RSRQ)，信号与干扰加噪声比(signal to interference plus noise ratio，SINR)等，在此不做限制。需要说明的是，本申请实施例中涉及的第二测量结果为最近一次向网络设备上报的测量结果，即第二测量结果为第一测量结果之前，最近一次向网络设备上报的测量结果。可选的，第一测量结果和第二测量结果为对应同一个测量标识的测量结果。
下面将针对基于第一测量结果确定第一测量事件是否被触发的几种情况分别进行说明。
情况1：当第一测量事件指示第一小区从可检测变为不可检测时，基于第一测量结果，确定第一测量事件是否被触发的实现可以理解为通过以下方式1-1～方式1-3确定：
方式1-1：
①在第一小区的第一测量结果小于或者等于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一小区的第一测量结果大于第一预设阈值或者第一小区可检测时，确定第一测量事件未被触发。或者，
②在第一小区的第一测量结果小于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一小区的第一测量结果大于或者等于第一预设阈值或者第一小区可检测时，确定第一测量事件未被触发。
举例来说，以第一小区的测量结果为RSRP，第一预设阈值为-120dBm为例。其中，假设第一测量结果为-125dBm，由于-125dBm＜-120dBm，因此可确定第一测量事件被触发。其中，又假设第一测量结果为-115dBm，由于-115dBm＞-120dBm，因此可确定第一测量事件未被触发。第一预设阈值可以在标准中预定义，也可以由网络设备配置。
需要说明的是，上述有关在确定第一小区不可检测时，确定第一测量事件被触发的实现也可以是终端设备基于自身的私有实现的，例如，终端设备根据自身的小区识别算法无法检测到第一小区，因此可确定第一小区不可检测。相应地，前述在确定第一小区可检测时，确定第一测量事件未被触发的实现也可以是终端设备基于自身的私有实现，例如，终端设备根据自身的小区识别算法检测到了第一小区，因此可确定第一小区可检测。一般来说，当终端设备基于自身的私有实现时，终端设备在标准定义的小区识别相关条件满足时，应当确定第一小区可检测；当第一小区的实际条件低于标准定义的小区识别相关条件时，终端设备也可能确定第一小区可检测。
方式1-2：
①在第二测量结果大于第一预设阈值或者第一小区可检测，且第一测量结果小于或者等于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果小于或者等于第一预设阈值，和/或第一测量结果大于第一预设阈值时，确定第一测量事件未被触发。或者，
②在第二测量结果大于或者等于第一预设阈值或者第一小区可检测，且第一测量结果小于或者等于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果小于第一预设阈值，和/或第一测量结果大于第一预设阈值时，确定第一测量事件未被触发。或者，
③在第二测量结果大于第一预设阈值或者第一小区可检测，且第一测量结果小于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果小于或者等于第一预设阈值，和/或第一测量结果大于或者等于第一预设阈值时，确定第一测量事件未被触发。或者，
④在第二测量结果大于或者等于第一预设阈值或者第一小区可检测，且第一测量结果小于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果小于第一预设阈值，和/或第一测量结果大于或者等于第一预设阈值时，确定第一测量事件未被触发。
举例来说，以第一小区的测量结果为RSRQ，第一预设阈值为5dB为例。其中，假设第一测量结果为4dB，第二测量结果为10dB，由于10dB＞5dB，且4dB＜5dB，因此可确定第一测 量事件被触发。其中，又假设第二测量结果为3dB，由于3dB＜5dB，因此可确定第一测量事件未被触发。
方式1-3：
①在第一预设时间内第一小区的所有第一测量结果皆小于或者等于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一预设时间内存在任一时刻对应的第一测量结果大于第一预设阈值或第一小区可检测时，确定第一测量事件未被触发。或者，
②在第一预设时间内第一小区的所有第一测量结果皆小于第一预设阈值或者第一小区不可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一预设时间内存在任一时刻对应的第一测量结果大于或者等于第一预设阈值或第一小区可检测时，确定第一测量事件未被触发。
也就是说，当第一小区在第一预设时间内(例如最近[X]s内)不可检测，或者，第一小区的第一测量结果在第一预设阈值以下时，可确定第一测量事件被触发，反之则认为第一测量事件未被触发。第一预设时间可以在标准中预定义，也可以由网络设备配置。
举例来说，以第一小区的测量结果为RSRQ，第一预设阈值为5dB为例。假设最近5s内测量出的第一测量结果分别为2dB，3dB和2dB，由于2dB，3dB和2dB皆小于5dB，因此，可确定第一测量事件被触发。由假设最近5s内测量出的第一测量结果分别为2dB，3dB和10dB，由于10dB＞5dB，因此，可确定第一测量事件未被触发。
可选的，当第一测量事件指示第一小区从可检测变为不可检测时，上述情况1的方式1-1～方式1-3中描述的用于判断第一测量事件被触发的一个或者多个条件可以理解为该第一测量事件的进入条件。
情况2：当第一测量事件指示第一小区从不可检测变为可检测时，基于第一测量结果，确定第一测量事件是否被触发的实现可以理解为通过以下方式2-1～方式2-3确定：
方式2-1：
①在第一小区的第一测量结果大于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一小区的第一测量结果小于或者等于第二预设阈值或者第一小区不可检测时，确定第一测量事件未被触发。或者，
②在第一小区的第一测量结果大于或者等于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一小区的第一测量结果小于第二预设阈值或者第一小区不可检测时，确定第一测量事件未被触发。其中，第一预设阈值的取值可以与第二预设阈值的取值相同，或者，第一预设阈值的取值也可以与第二预设阈值的取值不同，在此不做限制。
举例来说，以第一小区的测量结果为SINR，第二预设阈值为-6dB为例。其中，假设第一测量结果为-3dB，由于-3dB＞-6dB，因此可确定第一测量事件被触发。其中，又假设第一测量结果为-10dB，由于-10dB＜-6dB，因此可确定第一测量事件未被触发。
需要说明的是，有关终端设备基于自身的私有实现确定第一小区是否可检测的理解可参见前述有关私有实现的描述，在此不再进行赘述。
方式2-2：
①在第二测量结果小于或者等于第二预设阈值或者第一小区不可检测，且第一测量结果大于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果大于第二预设阈值，和/或第一测量结果小于或者等于第二 预设阈值时，确定第一测量事件未被触发。或者，
②在第二测量结果小于第二预设阈值或者第一小区不可检测，且第一测量结果大于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果大于或者等于第二预设阈值，和/或第一测量结果小于或者等于第二预设阈值时，确定第一测量事件未被触发。或者，
③在第二测量结果小于或者等于第二预设阈值或者第一小区不可检测，且第一测量结果大于或者等于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果大于第二预设阈值，和/或第一测量结果小于第二预设阈值时，确定第一测量事件未被触发。或者，
④在第二测量结果小于第二预设阈值或者第一小区不可检测，且第一测量结果大于或者等于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第二测量结果大于或者等于第二预设阈值，和/或第一测量结果小于第二预设阈值时，确定第一测量事件未被触发。
举例来说，以第一小区的测量结果为SINR，第二预设阈值为-6dB为例。其中，假设第一测量结果为-3dB，第二测量结果为-10dB，由于-10dB＜-6dB，且-3dB＞-6dB，因此可确定第一测量事件被触发。其中，又假设第一测量结果为-12dB，第二测量结果为-4dB，由于-4dB＞-6dB，且-12dB＜-6dB，因此可确定第一测量事件未被触发。
需要说明的是，有关终端设备基于自身的私有实现确定第一小区是否可检测的理解可参见前述有关私有实现的描述，在此不再进行赘述。
方式2-3：
①在第一预设时间内第一小区的所有第一测量结果皆大于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一预设时间内存在任一时刻对应的第一测量结果小于或者等于第二预设阈值或第一小区不可检测时，确定第一测量事件未被触发。或者，
②在第一预设时间内第一小区的所有第一测量结果皆大于或者等于第二预设阈值或者第一小区可检测时，确定第一测量事件被触发，否则认为第一测量事件未被触发，即在第一预设时间内存在任一时刻对应的第一测量结果小于第二预设阈值或第一小区不可检测时，确定第一测量事件未被触发。
也就是说，当第一小区在第一预设时间内(例如最近[X]s内)可检测，或者，第一小区的第一测量结果在第二预设阈值以上时，可确定第一测量事件被触发，反之则认为第一测量事件未被触发。
举例来说，以第一小区的测量结果为SINR，第二预设阈值为-6dB为例。假设最近5s内测量出的第一测量结果分别为-1dB，-2dB和-2dB，由于-1dB和-2dB皆大于-6dB，因此，可确定第一测量事件被触发。由假设最近5s内测量出的第一测量结果分别为-3dB，-5dB和-7dB，由于-7dB＜-6dB，因此，可确定第一测量事件未被触发。
需要说明的是，当第一测量事件指示第一小区从不可检测变为可检测时，上述情况2的方式2-1～方式2-3中描述的用于判断第一测量事件被触发的一个或者多个条件可以理解为该第一测量事件的进入条件。
可选的，上述情况1中描述的实现方式和情况2中描述的实现方式也可以分别作为一个测量事件的进入条件和离开条件，以指示终端设备上报第一小区从可检测变为不可检测的情况，以及上报第一小区从不可检测变为可检测的情况。具体地，当第一测量事件指示第一小区从 可检测变为不可检测时，该第一测量事件的进入条件可以为上述方式1-1～方式1-3中描述的任一项条件，该第一测量事件的离开条件可以为上述方式2-1～方式2-3中描述的任一项条件，因此，当满足进入条件时，终端设备可上报第一小区从可检测变为不可检测的情况，当满足离开条件时，终端设备上报第一小区从不可检测变为可检测的情况。当第一测量事件指示第一小区从不可检测变为可检测时，该第一测量事件的进入条件可以为上述方式2-1～方式2-3中描述的任一项条件，该第一测量事件的离开条件可以为上述方式1-1～方式1-3中描述的任一项条件，因此，当满足进入条件时，终端设备可上报第一小区从不可检测变为可检测的情况，当满足离开条件时，终端设备上报第一小区从可检测变为不可检测的情况。
情况3：第一测量事件指示第一小区的波束发生变化时，基于第一测量结果，确定第一测量事件是否被触发的实现可以理解为通过以下方式3-1～方式3-2确定：
方式3-1：
①在第二测量结果中第一波束的波束测量结果大于第三预设阈值或者第一波束可检测，且第一测量结果中第一波束的波束测量结果小于或者等于第三预设阈值或者第一波束不可检测时，确定第一测量事件被触发。反之，在第二测量结果中第一波束的波束测量结果小于或者等于第三预设阈值或者第一波束不可检测，和/或第一测量结果中第一波束的波束测量结果大于第三预设阈值或者第一波束可检测时，确定第一测量事件未被触发。或者，
②在第二测量结果中第一波束的波束测量结果大于或者等于第三预设阈值或者第一波束可检测，且第一测量结果中第一波束的波束测量结果小于或者等于第三预设阈值或者第一波束不可检测时，确定第一测量事件被触发。反之，在第二测量结果中第一波束的波束测量结果小于第三预设阈值或者第一波束不可检测，和/或第一测量结果中第一波束的波束测量结果大于第三预设阈值或者第一波束可检测时，确定第一测量事件未被触发。或者，
③在第二测量结果中第一波束的波束测量结果大于第三预设阈值或者第一波束可检测，且第一测量结果中第一波束的波束测量结果小于第三预设阈值或者第一波束不可检测时，确定第一测量事件被触发。反之，在第二测量结果中第一波束的波束测量结果小于或者等于第三预设阈值或者第一波束不可检测，和/或第一测量结果中第一波束的波束测量结果大于或者等于第三预设阈值或者第一波束可检测时，确定第一测量事件未被触发。或者，
④在第二测量结果中第一波束的波束测量结果大于或者等于第三预设阈值或者第一波束可检测，且第一测量结果中第一波束的波束测量结果小于第三预设阈值或者第一波束不可检测时，确定第一测量事件被触发。反之，在第二测量结果中第一波束的波束测量结果小于第三预设阈值或者第一波束不可检测，和/或第一测量结果中第一波束的波束测量结果大于或者等于第三预设阈值或者第一波束可检测时，确定第一测量事件未被触发。其中方式3-1中涉及的第三预设阈值可以为绝对阈值等，在此不做限制。第三预设阈值可以在标准中预定义，也可以由网络设备配置。
也就是说，在前一次上报的第一小区的测量结果(即第二测量结果)中存在某个波束或某几个波束在本次测量的测量结果(即第一测量结果)中的波束测量结果低于某个绝对门限或变得不可检测时，可确定第一测量事件被触发，反之认为第一测量事件未被触发。
需要说明的是，本申请中波束测量使用到的参考信号可以是SSB或CSI-RS等，在此不做 限制。为方便描述，以下举例中皆以SSB波束级别的测量结果为例进行示意性说明。
举例来说，以第一测量结果和第二测量结果为RSRQ，第三预设阈值为10dB，第二测量结果包括SSB1，SSB2和SSB3，且SSB1，SSB2和SSB3的波束质量分别为7dB，7dB和10dB为例。其中，假设第一测量结果中包括SSB1，且SSB1的波束质量为3dB，由于3dB＜10dB，因此，可确定第一测量事件被触发。又假设第一测量结果中包括SSB1和SSB2，且SSB1和SSB2的波束质量分别为13dB和11dB，由于13dB和11dB皆大于10dB，因此，可确定第一测量事件未被触发。
方式3-2：
①在第一测量结果中第二波束的波束测量结果大于第三预设阈值，且第二测量结果中不包括第二波束的波束测量结果时，确定第一测量事件被触发。反之，当第二测量结果中包括的第二波束，在第一测量结果中的波束测量结果小于或者等于第三预设阈值时，确定第一测量事件未被触发。或者，
②在第一测量结果中第二波束的波束测量结果大于或者等于第三预设阈值，且第二测量结果中不包括第二波束的波束测量结果时，确定第一测量事件被触发。反之，当第二测量结果中包括的第二波束，在第一测量结果中的波束测量结果小于第三预设阈值时，确定第一测量事件未被触发。
也就是说，当本次测量的测量结果(即第一测量结果)中存在新波束的波束测量结果高于某个绝对门限或相对门限时，可确定第一测量事件被触发。这里，新波束即可以理解为在第一测量结果中存在，但在第二测量结果中不存在的波束。
其中，方式3-2中涉及的第三预设阈值可以为绝对阈值或者也可以为相对阈值等，在此不做限制。例如绝对阈值可以设置为6dB，10dB等，相对阈值可以理解为是基于第二测量结果中的波束测量结果确定出的值。例如相对阈值可以设置为第二测量结果中最好的波束测量结果加3dB。为方便理解，以下皆以第三预设阈值为绝对阈值为例进行说明。
举例来说，以第一测量结果和第二测量结果为RSRQ，第三预设阈值为10dB，第二测量结果包括SSB1，SSB2和SSB3，且SSB1，SSB2和SSB3的波束质量分别为7dB，7dB和10dB为例。其中，假设第一测量结果中包括SSB1，SSB2和SSB5，且SSB5的波束质量为12dB，由于12dB＞10dB，因此，可确定第一测量事件被触发。又假设第一测量结果中包括SSB1，SSB2和SSB5，且SSB5的波束质量为8dB，由于8dB＜10dB，因此，可确定第一测量事件未被触发。
需要说明的是，上述方式3-1和方式3-2也可以进行结合以形成方式3-3，即方式3-3：在前一次上报的第一小区的测量结果(即第二测量结果)中存在某个波束或某几个波束在本次测量的测量结果(即第一测量结果)中的波束测量结果低于某个绝对门限或变得不可检测，且本次测量的测量结果(即第一测量结果)中存在新波束的波束测量结果高于某个绝对门限或相对门限时，可确定第一测量事件被触发。
举例来说，以第一测量结果和第二测量结果为RSRQ，第三预设阈值为10dB，第二测量结果包括SSB1，SSB2和SSB3，且SSB1，SSB2和SSB3的波束质量分别为7dB，7dB和10dB为例。其中，假设第一测量结果中包括SSB1，SSB2，SSB4和SSB5，且SSB1，SSB2，SSB4和SSB5的波束质量分别为3dB，2dB，4dB和20dB，由于存在SSB5的波束质量大于10dB，因此，可确定第一测量事件被触发。
S203、若确定第一测量事件被触发，则终端设备向网络设备发送测量报告。
在一些可行的实施方式中，若确定第一测量事件被触发，则终端设备可以向网络设备发 送测量报告。相应地，网络设备接收测量报告，该测量报告可以用于指示第一测量事件被触发。其中，测量报告中可包括第一测量结果，或者第一测量事件的进入条件或离开条件被触发等，在此不做限制。
可选的，在一些可行的实施方式中，在网络设备需要激活第一小区时，网络设备可以向终端设备发送用于激活第一小区的命令(即激活命令)。相应地，终端设备可以接收来自网络设备用于激活第一小区的命令。然后，终端设备可以根据第一小区的状态确定对第一小区的激活方式，进而基于相应的激活方式激活第一小区。需要说明的是，本申请实施例中第一小区的状态可以基于第一测量事件的触发结果确定。第一小区的状态可以包括已知状态，未知状态或不可用状态等，在此不做限制。
其中，不可用状态也可称作不可激活状态，即该第一小区不可用于数据传输，因此，若终端设备确定第一小区处于不可用状态，则终端设备可以在接收激活命令之后，可能不执行激活第一小区的步骤，不需要满足针对已知或未知SCell定义的激活时延要求。当终端设备确定第一小区处于已知状态时，终端设备可以基于已知状态对应的激活方式激活第一小区，满足针对已知SCell定义的激活时延要求。当终端设备确定第一小区处于未知状态时，终端设备基于未知状态对应的激活方式激活第一小区，满足针对未知SCell定义的激活时延要求。
可选的，在一种可能的实现中，当网络设备确定第一小区处于不可用状态时，网络设备也可以不向终端设备发送用于激活第一小区的命令，即激活命令。
可选的，在一些可行的实施方式中，在网络设备向终端设备发送用于激活第一小区的命令之前，网络设备还可以向终端设备发送第一信息，相应地，终端设备接收第一信息。该第一信息用于指示终端设备根据第一测量事件的触发结果，确定第一小区的状态。可选的，网络设备指示某个测量标识，该测量标识对应第一小区所在的测量目标和第一测量时间。终端设备根据该测量标识对应的第一测量结果，确定第一小区的状态。也就是说，网络设备可通过第一信息指示终端设备根据第一测量事件确定第一小区的状态，这样以便于终端设备确定在后续接收到激活命令时如何确定第一小区的状态，例如根据第一测量事件的触发结果确定第一小区的状态，或者根据一段时间内是否上报过第一小区的测量结果确定第一小区的状态。可理解的，网络设备可以将第一信息承载在RRC信令或媒体接入控制(media access control，MAC)控制元素(control element，CE)中发送给终端设备，或者，网络设备也可以将第一信息承载在前述测量配置信息中以发送给终端设备，即测量配置信息中除了包括测量目标，以及与测量目标关联的第一测量事件，还可以包括第一信息。
可选的，针对终端设备而言，可规定终端设备在测量配置(即测量配置信息)生效后的第一个测量周期内默认上报第一小区的首次测量结果，即在测量配置信息生效后的第一个测量周期内，无论测量配置信息中的第一测量事件是否被触发，终端设备皆需要向网络设备上报第一小区的首次测量结果。进而，可将第一个测量周期内得到的第一小区的首次测量结果作为第一小区的初始化测量结果，这样以便后续在第二个测量周期内，根据第二个测量周期内的测量结果与初始化测量结果的比较，确定是否触发第二个测量周期内的测量上报。
可选的，若未规定终端设备在测量配置(即测量配置信息)生效后的第一个测量周期内默认上报第一小区的测量结果作为第一小区的初始化测量结果，则终端设备和网络设备可默认第一小区的初始化状态为已知状态，即第一小区在没有终端设备上报的情况下默认为已知状态。
下面分别站在终端设备和网络设备角度，对终端设备和网络设备具体如何根据第一测量事件的触发结果，确定第一小区的状态的实现方式进行说明。可理解的，第一测量事件的触发结果包括第一测量事件被触发或第一测量事件未被触发。其中以下各种实现方式可单独存在，或与其他方式进行结合，在此不做限制。
针对终端设备而言：
方式1：当第一测量事件指示第一小区从可检测变为不可检测时，若第一测量事件未被触发，则终端设备确定第一小区处于已知状态。
可选的，在方式1下，终端设备需要满足第一小区处于已知状态下的激活时延要求。
方式2：当第一测量事件指示第一小区从可检测变为不可检测时，若第一测量事件被触发，则终端设备确定第一小区处于不可用状态。
可选的，在方式2下，终端设备不需要满足第一小区的激活时延要求。
方式3：第一测量事件指示第一小区从不可检测变为可检测时，若第一测量事件被触发，则终端设备确定第一小区处于已知状态。
可选的，在方式3下，终端设备需要满足第一小区处于已知状态下的激活时延要求。
方式4：当第一测量事件指示第一小区从可检测变为不可检测时，若第一测量事件未被触发，且测量目标的测量周期小于或者等于第四预设阈值，则终端设备确定第一小区处于已知状态。
可选的，在方式4下，终端设备需要满足第一小区处于已知状态下的激活时延要求。
方式5：当第一测量事件指示第一小区从可检测变为不可检测时，若第一测量事件未被触发，且测量目标的测量周期大于或者等于第四预设阈值，则终端设备确定第一小区处于未知状态。
可选的，在方式5下，终端设备需要满足第一小区处于未知状态下的激活时延要求。
方式6：当第一测量事件指示第一小区从不可检测变为可检测时，若第一测量事件被触发，且测量目标的测量周期小于或者等于第四预设阈值，则终端设备确定第一小区处于已知状态。
可选的，在方式6下，终端设备需要满足第一小区处于已知状态下的激活时延要求。
方式7：当第一测量事件指示第一小区从不可检测变为可检测时，若第一测量事件被触发，且测量目标的测量周期大于或者等于第四预设阈值，则终端设备确定第一小区处于未知状态。
可选的，在方式7下，终端设备需要满足第一小区处于未知状态下的激活时延要求。
终端设备确定第一小区的状态，除了根据第一测量事件的触发结果，还可能结合其它的条件，例如当前标准TS38.133中定义的第一小区在小区激活延迟期间保持可检测等。相应地，对于网络设备而言：
方式1：当第一测量事件指示第一小区从可检测变为不可检测时，在未接收到来自终端设备的测量报告时，网络设备确定第一小区处于已知状态。
方式2：当第一测量事件指示第一小区从可检测变为不可检测时，在接收到来自终端设备的测量报告时，网络设备确定第一小区处于不可用状态。
方式3：当第一测量事件指示第一小区从不可检测变为可检测时，在接收到来自终端设备的测量报告时，网络设备确定第一小区处于已知状态。
方式4：当第一测量事件指示第一小区从可检测变为不可检测时，在未接收到来自终端设备的测量报告，且确定测量目标的测量周期小于或者等于第四预设阈值时，网络设备确定 第一小区处于已知状态。
方式5：当第一测量事件指示第一小区从可检测变为不可检测时，在未接收到来自终端设备的测量报告，且确定测量目标的测量周期大于或者等于第四预设阈值时，网络设备确定第一小区处于未知状态。
方式6：当第一测量事件指示第一小区从不可检测变为可检测时，在接收到来自终端设备的测量报告，且确定测量目标的测量周期小于或者等于第四预设阈值时，网络设备确定第一小区处于已知状态。
方式7：当第一测量事件指示第一小区从不可检测变为可检测时，在接收到来自终端设备的测量报告，且确定测量目标的测量周期大于或者等于第四预设阈值时，网络设备确定第一小区处于未知状态。
需要说明的是，针对网络设备而言，若接收到来自终端设备的测量报告，则可确定第一测量事件被触发，即测量报告可以用于指示第一测量事件被触发。若未接收到来自终端设备的测量报告，则可以确定第一测量事件未被触发。
可选的，在一些可行的实施方式中，当第一测量事件指示第一小区的波束发生变化时，若终端设备基于测量配置信息测量得到的第一测量结果确定该第一测量事件被触发，则终端设备可以向网络设备发送的测量报告。相应地，网络设备接收来自终端设备的测量报告，该测量报告指示第一测量事件被触发，测量报告中可以包括第一测量结果，第一测量结果包括波束的波束测量结果。进一步地，网络设备可以根据第一测量事件更新激活第一小区时使用的波束。也就是说，在网络设备接收到该测量报告后，网络设备可以根据第一测量结果中包括的波束测量结果，确定在第一小区的激活过程中应该使用哪个发波束向终端设备发送CSI-RS或者跟踪参考信号(tracking reference signal，TRS)等参考信号辅助终端设备完成激活，以及确定在激活后应该使用哪个发波束对终端设备进行数据调度。
举例来说，假设测量报告的第一测量结果中包括SSB1，SSB2，SSB4和SSB5，且SSB1，SSB2，SSB4和SSB5的波束质量分别为3dB，2dB，4dB和10dB，则网络设备可以在激活过程中采用SSB5向终端设备发送CSI-RS或者TRS等参考信号辅助终端设备激活第一小区，或者，在第一小区激活后，采用SSB5对终端设备进行数据调度。
在本申请中，通过定义用于指示第一小区发生变化的第一测量事件，可使得当满足第一测量事件的触发条件时，终端设备上报第一测量事件对应的测量报告，进而降低了在激活第一小区之前，测量上报的信令开销以及降低了终端设备功耗。具体地，本申请中第一小区发生变化可包括第一小区从可检测变为不可检测、第一小区从不可检测变为可检测或第一小区的波束发生变化。其中，当第一测量事件指示第一小区从可检测变为不可检测，或者第一小区从不可检测变为可检测时，终端设备或网络设备还可以基于第一测量事件确定第一小区的状态，以便于后续根据第一小区的不同状态，确定不同的激活方式对第一小区进行激活。例如，当确定终端设备确定第一小区为已知状态时，可基于已知状态对应的激活方式激活第一小区，这样可以省略自动增益控制和小区粗定时搜索的步骤，大大降低激活时间。其中，当第一测量事件指示第一小区的波束发生变化时，网络设备还可以根据第一测量事件确定激活过程中使用的发送波束，或者，确定激活后调度终端设备使用的发送波束，这样有利于提高通信质量。
为使得小区激活场景下的方案更加清楚，下面结合图3中的流程图对本申请中的方案进行进一步说明。

S304、终端设备接收来自网络设备用于激活第一小区的命令。
在一些可行的实施方式中，在网络设备需要激活第一小区时，网络设备可以向终端设备发送用于激活第一小区的命令(即激活命令)。相应地，终端设备可以接收来自网络设备用于激活第一小区的命令。可选的，在一种实现中，当网络设备确定第一小区处于不可用状态时，网络设备也可以不向终端设备发送用于激活第一小区的命令。
可选的，在一些可行的实施方式中，在网络设备向终端设备发送用于激活第一小区的命令之前，网络设备还可以向终端设备发送第一信息，相应地，终端设备接收第一信息。该第一信息用于指示终端设备根据第一测量事件的触发结果，确定第一小区的状态。可选的，网络设备指示某个测量标识，该测量标识对应第一小区所在的测量目标和第一测量时间。终端设备根据该测量标识对应的第一测量结果，确定第一小区的状态。也就是说，网络设备可通过第一信息指示终端设备根据第一测量事件确定第一小区的状态，这样以便于终端设备确定在后续接收到激活命令时如何确定第一小区的状态，例如根据第一测量事件的触发结果确定第一小区的状态，或者根据一段时间内是否上报过第一小区的测量结果确定第一小区的状态。可理解的，网络设备可以将第一信息承载在RRC信令或媒体接入控制MAC CE中发送给终端设备，或者，网络设备也可以将第一信息承载在前述测量配置信息中以发送给终端设备，即测量配置信息中除了包括测量目标，以及与测量目标关联的第一测量事件，还可以包括第一信息。需要说明的是，本申请中所涉及的第一测量事件可以是定义的新事件，或者，第一测量事件也可以旧事件或已有事件，例如旧事件或已有事件也可以是标准TS38.331的第5.5.4.3条中定义的A2事件等，在此不做限制，即本申请可通过定义新事件或复用旧事件，并基于新事件或旧事件的触发结果，确定第一小区的状态。

其中，步骤S305的具体实现方式可参见上述图2步骤S203中的描述的方式1～方式7，这里不再进行赘述。
S306、终端设备根据第一小区的状态激活第一小区。
需要说明的是，在接收激活命令之后，若终端设备确定第一小区处于已知状态，则终端设备可以基于已知状态对应的激活方式激活第一小区，若终端设备确定第一小区处于未知状态，则终端设备可以基于未知状态对应的激活方式激活第一小区，若终端设备确定第一小区处于不可用状态，则终端设备可以在接收激活命令之后，可能不执行激活第一小区的步骤。
S307、网络设备更新激活第一小区时使用的波束。
需要说明的是，当网络设备接收到的测量报告中包括第一测量结果，第一测量结果包括波束的波束测量结果时，网络设备可以根据第一测量事件更新激活第一小区时使用的波束。也就是说，在网络设备接收到该测量报告后，网络设备可以根据第一测量结果中包括的波束测量结果，确定在第一小区的激活过程中应该使用哪个发波束向终端设备发送CSI-RS或者 TRS等参考信号辅助终端设备完成激活，以及确定在激活后应该使用哪个发波束对终端设备进行数据调度。
