Description

一种用于上报小区或载波信息的方法及装置
本申请要求于2021年5月6日提交中国国家知识产权局、申请号为202110492363.1、发明名称为“一种用于上报小区或载波信息的方法及装置”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
本申请涉及通信领域，并且更具体地，涉及一种用于上报小区或载波信息的方法及装置。
背景技术
随着通信技术的发展，网络对上下行峰值数据速率的要求越来越高，载波聚合(carrier aggregation，CA)可以将2个或更多的载波(component carrier，CC)聚合在一起以支持更大的传输带宽。在CA中，小区可以定义为主小区(primary cell)和辅小区(secondary cell)，其中，主小区包括一个上行(uplink，UL)载波和一个下行载波(downlink，DL)。
在灵活频谱接入(flexible spectrum access，FSA)技术中。不受限于CA的要求，小区内可以包含一个下行载波，多个上行载波，且对任意一个小区，上行载波所在的频段可能会高于下行载波所在的频段。因此，对于一些对频段要求更高的业务，或者在上下载波解耦的情形下，仅仅依靠下行载波的信号强度并不能满足传输性能的要求。
为此，如何提高对小区质量的判断的准确性是目前亟待解决的问题。
发明内容
本申请提供一种用于上报小区或载波信息的方法和装置，以期能使得对于小区质量的判断相对准确。进一步地，通过增加对于小区质量的判断的准确性，能够使得终端设备切换到更为符合要求的小区，降低由于终端设备切换到不合适的小区而需要重新切换的概率，从而避免因此而产生的开销和时延。

可选地，第一网络设备可以为邻基站，第二网络设备可以为服务基站。

情形1，向网络设备或第二网络设备发送第一小区的信号强度。第一小区的信号强度为第一小区的下行载波的信号强度。
情形2，向网络设备或第二网络设备发送第一小区的信号强度和所述第一小区的标识。第一小区的信号强度为第一小区的下行载波的信号强度。

情形7，向网络设备或第二网络设备发送第一小区的信号强度、第一小区的标识、至 少一个上行载波中满足第一条件的上行载波的信道状态信息和至少一个上行载波中满足第一条件的上行载波的标识。第一小区的信号强度为第一小区的下行载波的信号强度。
在上述任一情形中，可选的，第一小区的下行载波为第一下行载波。第一小区包括满足第一条件的第一上行载波和第一下行载波。
在上述任一情形中，可选的，第一小区的信号强度为第一小区的下行载波的信号强度。

在上述任一情形中，可选的，至少一个上行载波中满足第一条件的上行载波的信道状态信息，可以为至少一个上行载波中满足第一条件的上行载波的信道状态信息中最小的信道状态信息，或者至少一个上行载波中满足第一条件的具有最小的信道状态信息的上行载波的信道状态信息。
在上述任一情形中，可选的，至少一个上行载波中满足第一条件的上行载波的信道状态信息，可以为至少一个上行载波中满足第一条件的上行载波的信道状态信息的平均信道状态信息，或者至少一个上行载波中满足第一条件的各个上行载波的信道状态信息的平均值。可选的，当至少一个上行载波中满足第一条件的上行载波的信道状态信息为上述平均值时，可以在终端设备向第一网络设备或第二网络设备发送的信息中携带满足第一条件的上行载波的个数。
在上述方案中，通过确定至少一个上行载波是否满足条件，进一步确定第一小区，并把第一小区的信息上报给网络设备，能够满足不同业务的需求，并相对准确地定位到符合要求的小区。
结合第一方面，在第一方面的某些实现方式中，与上行载波相关联的下行载波与上行载波属于同一频段。
应理解，频段还可以理解为频点。例如，更高的频段可以理解为更高的频点。更低的频段可以理解为更低的频点。在上述方案中，与上行载波相关联的下行载波与上行载波属于同一频段，有助于可以根据与上行载波相关联的下行载波的信道状态，来近似该上行载波的信道状态。不会因为不同频点在信道上所经历的衰减不同，而产生信道状态估计的偏差。
结合第一方面，在第一方面的某些实现方式中，与上行载波相关联的下行载波与上行载波位于能近似彼此信道状态信息的频段中。
在上述方案中，与上行载波相关联的下行载波与上行载波位于能近似彼此信道状态信息的频段中，有助于可以根据与上行载波相关联的下行载波的信道状态，来获取该上行载波的信道状态。即使因为不同频点在信道上所经历的衰减不同，根据不同频点对应的一定的偏移量仍然可以根据一方近似估计另一方信道状态信息的值或者范围。
结合第一方面，在第一方面的某些实现方式中，与上行载波相关联的下行载波与上行载波属于第二小区。
在上述方案中，还存在传统的一个下行载波与一个上行载波。下行载波的信道状态信息可以被用来有效地近似上行载波的信道状态信息。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：根据与至少一个上行载波相关联的下行载波的信号强度，确定至少一个上行载波的信道状态指示信息。
在上述方案中，通过与上行载波与下行载波相关联，通过下行载波的信号强度可以确定上行载波的状态指示信息，能够减少信令的开销并降低时延。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：在至少一个上行载波上发送随机接入信号，该随机接入信号用于第一网络设备对至少一个上行载波的信道状态进行测量；从第一网络设备接收随机接入响应RAR，该RAR包括至少一个上行载波的信道状态信息。
在上述方案中，在至少一个上行载波上发送随机接入信号，可以提前随机接入信道的接入，减小时延造成的延迟，也减小了额外的系统开销。
结合第一方面，在第一方面的某些实现方式，该方法还包括：在至少一个上行载波上发送第一信号，该第一信号用于第一网络设备对至少一个上行载波的信道状态进行测量；从第二网络设备接收至少一个上行载波的信道状态指示信息。
在上述方案中，第一信号既可以被第一网络设备检测，也可以被用于第二网络设备检测。当用于第一网络设备检测时，可以不受TA不准所导致/所造成的影响，即第一网络设备确定信道状态信息时可以不受TA不准造成的估计偏差。当用于第二网络设备检测时，可以使得第二网络设备基于此实现获取信道状态信息的目的。因此不造成额外的系统开销。
结合第一方面，在第一方面的某些实现方式中，第一信号还用于第二网络设备对至少一个上行载波的信道状态指示信息进行测量。
在上述方案中，第一信号可以作为特殊设计的信号，不受TA不准所导致/所造成的信号估计不准，从而避免基于该信号检测做出的错误判断。此外，第一信号相对前导码来说，开销较少。所以，通过第一信号进行信道状态信息的判断，兼具了减少系统开销，以及避免TA不准的影响。还能被第二网络设备用作通常的信道状态判断。
结合第一方面，在第一方面的某些实现方式中，第一信号为前端带有循环前缀CP的序列或远程干扰管理RIM信号。
在上述方案中，第一信号为带有CP的序列或RIM信号，有助于网络设备检测时不受TA影响。
结合第一方面，在第一方面的某些实现方式中，上行载波的信道状态信息包括下述项中的至少一项：参考信号接收功率，参考信号强度、路径损耗、信道状态指示信息。
第二方面，提供了一种用于上报小区或载波信息的方法，该方法包括：接收下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，至少一个上行载波中满足第一条件的上行载波的信道状态指示信息，至少一个上行载波中满足第一条件的上行载波的标识；其中，至少一个上行载波属于第一小区，第一小区为第一网络设备的小区，第一条件为下述项中的至少一项：与上行载波相关联的下行载波的信号强度大于或等于第一阈值；上行载波的信道状态信息大于或等于第二阈值。
应理解，上述接收下述项中的至少一项可以是第一网络设备接收下述项中的至少一项，也可以为第二网络设备接收下述项中的至少一项，其中，第一网络设备可以是邻基站，第二网络设备可以为服务基站。
可选地，上述方案还可以表达为，第一网络设备或第二网络设备接收第一信息，该第 一信息包括下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，第一上行载波的信道状态指示信息，第一上行载波的标识；其中，第一上行载波满足第一条件，第一上行载波和第一下行载波属于第一小区，第一小区为第一网络设备的小区。
可选地，上述方案还可以表达为，第一网络设备或第二网络设备接收第一信息，该第一信息包括下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，第一小区的满足第一条件的第一上行载波的信道状态指示信息，第一小区的满足第一条件的上行载波的标识，其中，第一小区的上行载波满足第一条件，第一小区为第一网络设备的小区。
在上述方案中，接收第一小区的信息，该第一小区根据第一上行载波是否满足第一条件确定，从而能够满足不同业务的需求，并相对准确地定位到符合要求的小区。
结合第二方面，在第二方面的某些实现方式中，与上行载波相关联的下行载波与上行载波属于同一频段。
结合第二方面，在第二方面的某些实现方式中，接收下述项中的至少一项为第一网络设备接收下述项中的至少一项时，该方法还包括：第一网络设备在至少一个上行载波上接收随机接入信号；第一网络设备根据随机接入信号对至少一个上行载波的信道状态进行测量；第一网络设备发送随机接入响应RAR，RAR包括至少一个上行载波的信道状态信息。

在移动通信系统100中，无线接入网设备120是终端设备通过无线方式接入到该移动通信系统中的接入设备。该无线接入网设备120可以是：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为LTE系统中的网络设备或NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备，如汇聚单元(central unit，CU)、分布式单元(distributed unit，DU)或基带单元(baseband unit，BBU)等，还可以是未来通信系统中的网络设备。应理解，本申请的实施例中，对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中，无线接入网设备简称网络设备，如果无特殊说明，在本申请中，网络设备均指无线接入网设备。网络设备110和网络设备120可以是与终端设备通信的设备，每个网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端设备进行通信。在本申请中，网络设备可以是指网络设备本身，也可以是应用于网络设备中完成无线通信处理功能的芯片。在本申请中，网络设备还可以是上述网络设备的任意组合。
另外，在本申请实施例中，接入网设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与接入网设备进行通信。该小区可以是接入网设备(例如基站)对应的小区。小区可以属于宏基站，也可以属于小小区(small cell)对应的基站。这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。

此外，在本申请实施例中，终端设备还可以是物联网(Internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
图1示例性地给出了两个网络设备和一个终端设备。网络设备110和网络设备120可以为分布式基站，例如，网络设备110包括一个射频拉远单元(remote radio unit，RRU)111，网络设备120包括两个RRU，分别为121和122。其中，网络设备可以为BBU，BBU与RRU间的接口，可以是光纤接口，也可以是无线接口。此外，网络设备110和网络设备120也可以为异构网络下的基站，例如，网络设备110包括一个微基站(或TRP)111，网络设备120包括两个微基站(或TRP)，分别为121和122。其中，微基站(或TRP)与基站间的接口，可以是光纤接口，也可以是无线接口。
上述接口可以是理想回传(backhaul)链路也可以是非理想回传链路。当接口为光纤接口时，信令交互可以通过X2或Xn接口；当接口为无线接口时，信令交互可以通过空口信令。本申请下述示例中以X2接口作为示例，可以拓展到任何情形。本申请下述以分布式基站作为示例，但不限于该示例。
可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例不限于此。
本申请下述以切换作为示例，同样可以应用于多链接链路增加或转换。其中多链接可以包含两条链路的链接(即双链接)或者多于两条链路的链接。应理解，下述“切换到”，可以替换为“多链接到”，不再一一详述。
在本申请实施例的描述中，将以终端设备130从源小区切换到目标小区为例进行说明。应理解，这里的源小区和目标小区可以是同一网络设备下的两个不同的小区，也可以是同网络下的两个小区。如图1所示，终端设备130在源小区110中，可以从位置1切换带位置2，实现同一个网络设备110下的不同小区的切换；也可以从源小区110切换到目标小区121，如图1中位置1到位置3的切换，实现不同网络设备下的不同小区间的切换。对于这两种切换场景，都是以小区为单位进行的切换，源小区和目标小区是否位于同一个网络设备内，本申请并不限定。
在载波聚合(component aggregation，CA)技术中，小区可以分为主小区(primary cell， Pcell)和辅小区(secondary cell，Scell)。其中，Pcell包含一个上行载波(uplink component carrier，UP CC)和一个下行载波(downlink component carrier，DL CC)，Pcell中的上行载波和下行载波位于同一个频段。Scell包含一个上行载波和一个下行载波，Scell中的上行载波和下行载波也位于同一个频段。在双链接技术中，除了上述定义，辅小区还可以进一步区分为主辅小区(primary Scell，PScell)和普通的Scell。无论是PScell还是普通的Scell，都包括一个上行载波和一个下行载波，每个Scell中的上行载波和下行载波均位于同一个频段。除此之外，目前还存在增补上行(supplementary UL，SUL)或超级上行(super UL，SUL)技术，在该技术中。一个小区包括普通下行(normal DL，NDL)、普通上行(normal UL，NUL)和SUL。NDL和NUL位于同一个频段，SUL位于其他频段，SUL所在的频段低于NDL和NUL所在的频段。
可以看出，在上述技术中，每个小区中都存在与该小区中的上行载波处于同一个频段，或者所在频段高于该小区中的上行载波的下行载波。由于这样的下行载波的信号强度可以用于推测上行载波的信道状态，因此，在选择目标小区时，无论是上述哪种技术，均可以依靠小区内的下行载波的信号强度判断该小区是否适合作为目标小区。
然而，在灵活频谱接入(flexible spectrum access，FSA)技术中，一个小区可以包括一个下行载波和多个上行载波，上行载波所在的频段可以不同，且单个上行载波所在的频段不一定如上述技术中那样低于或等于下行载波所在的频段，也可能高于下行载波所在的频段。
示例性地，小区的构成可以为[B1 DL，B0 UL/B2 UL/B3 UL/B4 UL]，即一个小区包括一个频段B1下的下行载波、一个频段B0下的上行载波、一个频段B2下的上行载波、一个频段B3下的上行载波和一个频段B4下的上行载波。其中，B0<B1<B2<B3<B4，或者说，B0、B1、B2、B3和B4各自对应的频点依次增大。
在FSA技术中，小区可以分为包含与下行载波同频段的上行载波的小区，以及不包含与下行载波同频段的上行载波的小区。其中，不包含与下行载波同频段的上行载波的小区可进一步分为：包含更高频段的上行载波的小区和包含更低频段的上行载波的小区。包含更低频段的上行载波的小区的容量相对受限。而对于包含更高频段的上行载波的小区，所在频段低于该小区中的上行载波的下行载波不适合用于推测该上行载波的信道状态。由此可见，对于FSA技术，仅依靠下行载波的信号强度进行判断不一定能够准确地判断该小区是否适合作为目标小区。因此，如何去获取这些相对其中所包含的下行载波而言更高频段的上行载波的信道状态是目前面临的问题。此外，即使是对于包含与下行载波同频段的上行载波的小区以及包含更低频段和上行载波的小区，获取上行载波的信道状态也有利于更准确地判断该小区是否适合作为目标小区。
本申请提出了一种用于上报小区或载波信息的方法，能够通过上报小区或载波信息，使得对于小区质量的判断相对准确。
本申请中，当第一小区中的至少一个上行载波位于毫米波波段时，本申请任何实施例同样适用于基于波束的情形。本申请中，“根据”也可以理解为“基于”。本申请中，所有用于网络侧切换的操作，也适用于终端设备与网络侧的多链接情形。本申请实施例中示出的单个执行主体所执行的处理也可以被划分为由多个执行主体执行，这些执行主体在逻辑上和/或在物理上分离，例如，网络设备所执行的处理可以被划分为由CU、DU和无线 电单元(radio unit，RU)中的至少一个执行。为便于理解本申请实施例，首先对本申请中涉及到的术语做简单说明。
测量上报事件包括事件(Event)A1、A2、A3、A4、A5、A6、B1、B2、B1-NR和B2-NR。下面对各个事件进行一一说明。
事件A1：当服务基站所属的小区的信号强度变得优于门限值时，触发事件A1。
事件A2：通常用于在终端设备向小区边缘移动时触发移动性过程。
事件A3：当邻小区的偏移量超过特定小区(Pcell或PScell)时，触发事件A3。特定小区是主小区组(master cell group，MCG)或辅小区组(secondary cell group，SCG)的主要服务小区。
事件A4：当相邻小区变得优于定义的阈值时，触发事件A4。
事件A5：当某个特定小区变得比阈值1差，而相邻小区变得比阈值2好时，触发事件A5。事件A5是事件A2和事件A4的组合。
事件A6：当相邻小区超过辅小区的偏移量时，触发事件A6。偏移量可以是正的，也可以是负的。
事件B1：其他无线接入技术(radio access technology，RAT)中的目标小区优于特定的阈值，并且能够提供足够的覆盖。
事件B1-NR：NR中的目标小区优于特定的阈值，并且能够提供足够的覆盖。
事件B2：当主服务小区变得比阈值1差，而相邻的RAT小区变得比阈值2好时，触发事件B2。当主要服务小区变弱时，这可用于触发RAT的移动程序。系统间邻居小区测量用于确保目标小区提供足够的覆盖。
事件B2-NR：当主服务小区变得比阈值1差，而NR小区变得比阈值2好时，触发事件B2-NR。当主要服务小区变弱时，这可用于触发RAT的移动程序。系统间邻居小区测量用于确保目标小区提供足够的覆盖。
图2是本申请实施例提出的一种用于上报小区或载波信息的方法的示意性流程图。如图2所述，该方法涉及终端设备和网络设备，其中，网络设备包括第一网络设备和/或第二网络设备。
第一网络设备可以是邻基站，第二网络设备可以是服务基站，终端设备需要从服务基站切换到邻基站。邻基站可以被称为目的基站，服务基站可以被称为源基站。这种情况下，第一网络设备包括至少一个灵活小区，第二网络设备可以包括灵活小区，也可以不包括灵活小区。
或者，第一网络设备和第二网络设备可以是同一网络设备，即，第一网络设备和第二网络设备都是服务基站，终端设备从服务基站的一个小区切换到服务基站的另一个小区。这种情况下，第一(第二)网络设备包括至少一个灵活小区。
或者，第一网络设备和第二网络设备可以是终端设备多链接链路所对应的设备。示例性地，第一网络设备为第二网络设备覆盖范围下所属的至少一个小站；或者，第一网络设备和第二网络设备为分别连接核心网的设备。其中，第一网络设备和第二网络设备为分别连接核心网的设备可以理解为：第一网络设备和第二网络设备均可以直接与核心网进行通信，若第一网络设备和第二网络设备不是直接连接核心网的设备，其需要通过回传链路将接收到的数据转向另一个基站，才能完成通信。第一网络设备为第二网络设备覆盖下所述 的至少一个小站可以理解为需要回传链路的情形。而第一网络设备和第二网络设备为分别连接核心网的设备可以理解为第一网络设备和第二网络设备是平等的，没有附属关系。
在本申请的实施例中，第一网络设备包括的灵活小区被称为第一小区。灵活小区可以被理解为包括至少一个上行载波和第一下行载波，至少一个上行载波中的各个上行载波对应频段可以大于、小于或等于第一下行载波对应的频段。灵活小区也可以称之为新型小区、弹性小区、载波数可变的小区或上行载波数可变的小区等，上述名称仅作为示例。
灵活小区以外的小区被称为非灵活小区，包括但不限于载波聚合小区。非灵活小区也可以称之为通常小区、现有标准规定的小区、或者标准小区等，上述名称仅作为示例。可选地，除了灵活小区，第一网络设备还可以包括非灵活小区；第二网络设备也可以包括非灵活小区。
此外，与第一小区中的上行载波相关联的下行载波被称为第二下行载波，这种相关联可以被理解为第二下行载波可以被用于推断该上行载波的信道质量。第二下行载波可以不属于任何小区，也可以属于第二网络设备的其他小区，该小区被称为第二小区。第二小区中可以不包含该上行载波。第二上行载波不属于任何小区的方式以及第二小区中不包含该上行载波的方式可以应用于第二网络设备(邻基站或与服务基站)无载波聚合小区的场景下。这种情况下，该上行载波与第二下行载波的关联关系可以从服务基站或邻基站获取。从服务基站获取，可以是从广播消息或者专有信令中获取。从目的基站获取，可以是从广播消息获取。第二小区还可以是包括该上行载波的载波聚合小区。这种方式可以应用于在第二网络设备(邻基站或服务基站)有载波聚合小区的场景下。这种场景下，该上行载波与第二下行载波的关联关系可以是从目的基站获取，例如，从目的基站的辅小区获取。当然，也可以是目的基站通过基站间接口发送给源基站，终端设备从源基站获取。在上述两种场景下，第二下行载波与该上行载波可以属于同一个频段，第二下行载波位于的频段也可以大于该上行载波位于的频段。
图2中具体的方法包括：
步骤S210，终端设备确定至少一个上行载波是否满足第一条件，至少一个上行载波属于第一小区。第一小区为第一网络设备的小区。
本步骤中，终端设备确定至少一个上行载波是否满足第一条件可以理解为：判断第一小区中是否存在满足第一条件的上行载波。针对至少一个上行载波中满足第一条件的上行载波进行描述的话，步骤S210也可以表达为：终端设备确定第一上行载波满足第一条件，第一上行载波属于第一小区。
终端设备确定至少一个下行载波满足第一条件，第一条件可以为与上行载波相关联的下行载波的信号强度大于或等于第一阈值，即，第二下行载波的信号强度大于或等于第一阈值。
示例性地，终端设备获取目的基站的第二下行载波的信号强度。当该第二下行载波满足大于或等于第一阈值时，该第二下行载波可以为目标载波，也可以理解为，该第二下行载波关联的上行载波为目标载波，上行载波属于的第一小区为目标小区。终端设备获取目的基站的第二下行载波的信号强度，可以理解为，终端设备在第二下行载波上检测参考信号，确定参考信号的信号强度。
其中，第一阈值可以是协议规定、服务基站配置或目的基站配置。当第一阈值为目的 基站配置时，其可以是目的基站通过广播消息发送，终端设备从广播消息中获取。本申请实施例对此不做任何限定。
在一种可能的实现方式中，终端设备检测至少一个上行载波相关联的下行载波的信号强度，可以推出至少一个上行载波的信道状态信息，并判断该至少一个上行载波的信道状态信息是否大于或等于第二阈值。当存在上行载波的信道状态指示信息大于或等于第二阈值时，可以确定该上行载波为目标载波，上行载波属于的第一小区为目标小区。
其中，第二阈值可以是协议规定、服务基站配置或目的基站配置。当第二阈值为目的基站配置时，其可以是目的基站通过广播消息发送，终端设备从广播消息中获取。本申请实施例对此不做任何限定。
其中，第一上行载波的信道状态信息包括下述项中的至少一项：参考信号接收功率，参考信号强度，路径损耗，信道状态信息。或者，第一上行载波的信道状态信息包括下述项中的至少一项：参考信号接收功率的范围，参考信号强度的范围，路径损耗的范围，信道状态信息的范围。
需要注意的，第一阈值和第二阈值可以相同，也可以不同，本申请实施例对此不限定。

可选的，该RAR包括至少一个上行载波的信道状态信息，至少一个上行载波的信道状态信息为第一网络设备所确定的。当第二网络设备接收到该随机接入信号后，对该至少一个上行载波的信息状态进行测量。第一网络设备判断该至少一个上行载波的信道状态信息是否大于或等于第二阈值。当存在上行载波的信道状态指示信息大于或等于第二阈值时，第一网络设备将在该上行载波的信道状态指示信息包含于RAR之中。
可选地，终端设备在至少一个上行载波上发送第一信号，更具体地，终端设备在至少一个上行载波上向第一网络设备和/或第二网络设备发送第一信号。当第一网络设备接收该第一信号后，对该至少一个上行载波的信息状态进行测量，并向终端设备发送至少一个上行载波的信道状态信息，或者向第二网络设备发送至少一个上行载波的信道状态信息，并由第二网络设备向终端设备发送至少一个上行载波的信道状态信息。终端设备接收至少一个上行载波的信道状态信息，并判断该至少一个上行载波的信道状态信息是否大于或等于第二阈值。当存在上行载波的信道状态指示信息大于或等于第二阈值时，可以确定该上行载波为目标载波，上行载波属于的第一小区为目标小区。
该第一信号可以为前端带有循环前缀(cyclic prefix，CP)的序列或远程干扰管理(remote interference management，RIM)信号。
示例性地，第一信号可以为信道探测参考信号(sounding reference signal，SRS)、信 道状态信息参考信号(channel state information reference signal，CSI-RS)、解调参考信号(demodulation reference signal，DMRS)中至少一项，其还可以为一个新定义的信号。作为一种示例，承载第一信号的资源在时域上包括M个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，每个符号承载的是相同的第一信号。且在M个OFDM符号之前(或者最前端)添加X个CP，其中，M为正整数，X≥1。作为一种示例，该新定义的信号可以为类似RIM信号。
步骤S220，终端设备向第一网络设备或第二网络设备发送第一信息。即发送下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，至少一个上行载波中满足第一条件的上行载波的信道状态信息，至少一个上行载波中满足第一条件的上行载波的标识。
相应地，在步骤S220中，第一网络设备或第二网络设备接收第一信息，即接收下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，至少一个上行载波中满足第一条件的上行载波的信道状态信息，至少一个上行载波中满足第一条件的上行载波的标识。
若第一网络设备接收第一信息，终端设备确定切换到到第一网络设备下，即第一网络设备接收第一信息后默认该终端设备会切换到第一小区。
若第二网络设备接收第一信息，第二网络设备接收到该第一信息后，可以根据该第一信息确定终端设备具体切换到哪个小区。
具体而言，在步骤S210中，当至少一个上行载波中存在满足第一条件的上行载波时，终端设备向第一网络设备或者第二网络设备上报第一小区的相关信息，或者说，终端设备确定的目标小区或目标载波的相关信息，以下将上述信息简称为第一信息。该第一小区的相关信息可以为第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，至少一个上行载波中满足第一条件的上行载波的信道状态信息，至少一个上行载波中满足第一条件的上行载波的标识中的至少一项。
其中，向第一网络设备或第二网络设备发送第一信息，该第一信息包括下述项中的至少一项：第一小区的信号强度，第一小区的标识，第一小区的下行载波的信号强度，第一上行载波的信道状态指示信息，第一上行载波的标识。也可以理解为该第一信息包括下述几种情形：
情形1：当至少一个上行载波中存在满足第一条件的上行载波时，向第一网络设备或第二网络设备发送第一小区的信号强度。第一小区包括满足第一条件的第一上行载波和第一下行载波。
当第一网络设备下的第一小区有满足第一条件的上行载波，说明第一小区可以作为候选切换小区或候选多链接小区，因此上报第一小区的信号强度有助于网络设备侧进行有效的切换或者多链接操作。当上报给第一网络设备时，可以直接切换或者多链接到第一网络设备；当上报给第二网络设备时，由第二网络设备发起切换或者多链接到第一网络设备的操作。

具体而言，配置信息可以是邻基站中待测量小区、参考信号配置中的至少一项。该配置信息为服务基站和邻基站通过接口进行信息的传输。在本申请中，服务基站和邻基站之 间可以通过现有的X2/Xn接口消息来传递信息，或者通过其他X2/Xn接口消息，例如专门的消息，来传递信息，本申请在此不限定。
若邻基站中的小区为灵活小区，配置信息还包括关联配置信息。
关联配置信息包括第一关联配置信息，即包括灵活小区中的上行载波与第二下行载波的关联关系。作为一种实施例，邻基站除灵活小区之外还存在灵活小区中的上行载波和第二下行载波的关联关系。其中，第二下行载波可以属于别的小区，也可以不属于任何小区。别的小区可以为灵活小区或现有载波聚合或双链接中的小区。例如，第一关联配置信息，包括DCC1与UCC0的关联关系，DCC2与UCC2的关联关系，DCC3与UCC3的关联关系，DCC4和UCC4的关联关系中的至少一个。作为另一种实施例，邻基站除灵活小区之外还存在其他小区(以下称为第二小区)，第二小区包括第二下行载波和上行载波，即该第一关联配置信息为第二小区的第二下行载波和第二小区中的上行载波的关联关系。
关联配置信息还包括第二关联配置信息，即灵活小区中的下行载波和上行载波的关联关系，即灵活小区中包括第一下行载波和至少一个上行载波。该第二关联配置信息为灵活小区中的第一下行载波和灵活小区中的至少一个上行载波的关联关系。第二关联配置信息，包括DCC1与UCC2、UCC3的关联关系，DCC5和UCC0、UCC4的关联关系。

应理解，上文仅为便于理解，列举了服务基站的小区数量和各个小区的上下行载波的关联关系，但这不应对本申请构成任何限定。本申请对于服务基站的小区数量和各个小区的上下行载波的关联关系的对应关系不作限定。
S320，终端设备检测第一下行载波的信号强度，确定第一下行载波的信号强度满足测量上报事件。
邻基站在第一下行载波上向终端设备发送参考信号，即第一下行载波上的参考信号。其中，第一下行载波为灵活小区中的下行载波，如图4中的DCC1和DCC5。
具体而言，终端设备接收到第一下行载波上的参考信号后，可以根据该参考信号检测第一下行载波的信号强度，终端设备判断第一下行载波的信号强度是否满足测量上报事件。 该测量上报事件包括事件A1、A2、A3、A4、A5、A6、B1、B2、B1-NR、B2-NR中至少一项，或者终端设备判断第一下行载波的信号强度是否大于或等于第三阈值，该第三阈值可以由服务基站或邻基站确定。在终端设备确定第一下行载波的信号强度满足测量上报事件的情况下，可以将第一下行载波所在的灵活小区确定为第一候选小区。
本申请中，邻基站也可以称之为目标基站。
本申请中，终端设备判断第一下行载波的信号强度是否满足测量上报事件，也可以替换为终端设备判断第一下行载波的信号强度是否第二条件。其中，第二条件包含：第一下行载波的信号强度大于或等于第三阈值。同样的，终端设备判断第一下行载波的信号强度是否满足测量上报事件，也可以理解为终端设备判断第一下行载波的信号强度满足测量上报事件；终端设备判断第一下行载波的信号强度是否第二条件，也可以理解为终端设备判断第一下行载波的信号强度第二条件。
以测量上报事件A3，第一下行载波的信号强度以RSRP为例进行说明。如图4所示，第一下行载波包括DCC1和DCC5，其中，终端设备检测DCC1的信号强度为RSRP#1，检测DCC5的信号强度为RSRP#2。若RSRP#1和RSRP#2均满足测量上报事件A3。终端设备可以确定小区#1和小区#2为第一候选小区。
需要说明的是，步骤S310和步骤S320之间并没有严格的顺序关系，即S320可以在S310之前执行，或者S320可以在S310之后执行，或者二者同时执行等，本申请实施例对这两个步骤的顺序不做任何限定。
S330，终端设备确定第二下行载波的参考信号是否满足第一阈值。
邻基站在第二下行载波上向终端设备发送参考信号，即第二下行载波上的参考信号。
示例性地，该第二下行载波上的参考信号可以为邻基站的RRU和BBU向终端设备发送，如图4所示，邻基站包括BBU和至少一个RRU(图中示出了3个，即RRU#1、RRU#2和RRU#3)，DCC1上的参考信号为邻基站的BBU向终端设备发送，DCC2上的参考信号为邻基站的RRU#1向终端设备发送，DCC4上的参考信号为邻基站的RRU#2向终端设备发送，DCC3上的参考信号为邻基站的RRU#3向终端设备发送。
S340，终端设备确定第一小区，第一小区为包括与信号强度满足第一阈值的第二下行载波相关联的上行载波以及第一下行载波的小区。或者，终端设备也可以不确定第一小区，仅将信号强度满足第一阈值的第二下行载波关联的上行载波和/或第一下行载波确定为需要上报的载波。
具体而言，终端设备检测第一下行载波的信号强度满足测量上报事件，并确定第一候选小区，可以通过第一候选小区中的上行载波确定目标小区(第一小区)。
作为一种可能的实现方式，终端设备可以通过检测第二下行载波的参考信号确定第一小区，即当第二下行载波的参考信号大于或等于第一阈值时，终端设备可以确定第二下行载波关联的上行载波属于的灵活小区为第一小区。
示例性地，在步骤S320中，终端设备确定DCC1对应的信号强度和DCC5对应的信号强度满足测量上报事件，终端设备通过第二关联配置信息，可以确定该DCC1与UCC2、UCC3关联，DCC5与UCC0、UCC4关联，通过第一关联配置信息，可以确定UCC2与DCC2关联，UCC3与DCC3关联，UCC0与DCC1关联，UCC4与DCC4关联。终端设备基于DCC2、DCC3、DCC1和DCC4上的参考信号，检测信号强度，进一步将每个第二 下行载波对应的信号强度与第一阈值比较。以参考信号强度为RSRP，第一阈值为a为例，DCC1的考参信号强度为RSRP#1，DCC2的参考信号强度为RSRP#2，DCC3的参考信号强度为RSRP#3，DCC4的参考信号强度为RSRP#4。若RSRP#2大于a，RSRP#1、RSRP#3和RSRP#4均小于a，终端设备可以确定DCC2关联的UCC2为需要进行业务传输的上行载波(第一上行载波)，进一步终端设备可以确定DCC2关联的UCC2所在的灵活小区为第一小区，即小区#1为第一小区。
作为另一种可能的实现方式，终端设备可以通过检测第二下行载波的参考信号推出与其相关联的上行载波的信道状态信息，并将根据上行载波的信道状态信息确定第一小区。即当上行载波的信道状态信息大于或等于第二阈值时，终端设备可以确定该上行载波属于的灵活小区为第一小区。
示例性地，在步骤S320中，终端设备确定DCC1对应的信号强度和DCC5对应的信号强度满足测量上报事件，终端设备通过第二关联配置信息，可以确定该DCC1与UCC2、UCC3关联，DCC5与UCC0、UCC4关联，通过第一关联配置信息，可以确定UCC2与DCC2关联，UCC3与DCC3关联，UCC0与DCC1关联，UCC4与DCC4关联。终端设备基于DCC2、DCC3、DCC1和DCC4上的参考信号，检测参考信号强度，进一步推出与第二下行载波相关联的上行载波的信道状态信息，并将上行载波的信道状态信息与第二阈值比较。以第二下行载波的参考信号强度为RSRP，上行载波的信道状态信息为RSRP，第二阈值为b为例，DCC1的参考信号强度为RSRP#1，可推出DCC1关联的UCC0的信道状态信息为RSRP#A；DCC2的参考信号强度为RSRP#2，可推出DCC2关联的UCC2的信道状态信息为RSRP#B；DCC3的参考信号强度为RSRP#3，可推出DCC3关联的UCC3的信道状态信息为RSRP#B，DCC4的参考信号强度为RSRP#4，可推出DCC4关联的UCC4的信道状态信息为RSRP#D。若RSRP#B大于b，RSRP#A、RSRP#C和RSRP#D均小于b，终端设备可以确定UCC2为需要进行业务传输的上行载波(第一上行载波)，进一步终端设备可以确定DCC2关联的UCC2所在的灵活小区为第一小区，即小区#1为第一小区。
可选地，第一阈值可以为网络设备配置，例如，第一阈值可以为服务基站通过信令配置，该信令包括但不限于RRC信令。再例如，第一阈值可以为邻基站通过广播消息配置，包括但不限于辅助信息块(secondary information block，SIB)发送的广播消息。
可选地，第二阈值可以为网络设备配置。例如，第一阈值可以为服务基站通过信令配置，该信令包括但不限于RRC信令。再例如，第一阈值可以为邻基站通过广播消息配置，包括但不限于SIB发送的广播消息。
S350，终端设备向服务基站发送第一信息。
具体而言，终端设备确定第一小区后，将该第一小区相关的信息发送至服务基站，即终端设备向服务基站发送第一信息。或者，终端设备确定第一小区后，将该第一小区相关的信息发送至邻基站，即终端设备向邻基站发送第一信息。该第一小区相关的信息包括第一小区的信号强度，第一小区的标识，第一上行载波的标识，第一下行载波的信号强度或第一上行载波的信道状态信息中至少一项。
其中，第一小区的信号强度可以为第一小区的平均信号强度、第一小区的最小的信号强度或第一小区的最大的信号强度等。
可选地，第一小区相关的信息还可以包括第一上行载波的个数。
示例性地，在步骤S340中确定小区#1为第一小区，终端设备向服务基站发送的第一信息可以是小区#1的标识，小区#1中DCC1信号强度、UCC2信号强度和UCC3信号强度的平均值，小区#1中UCC#2的标识，小区#1中DCC1的信号强度、小区#1中UCC2的信道状态指示信息中至少一项。
在小区切换时，对于同小区的一个下行载波对应多个上行载波的情形，当多个上行载波分布于不同的射频拉远站点时，终端设备在切换中既判断下行载波又判断上行载波有助于正确的选择切换目标小区，避免误选到不能满足上行业务的小区上。这主要是考虑上行载波的频点比较高，以及上行频点分布于不同的RRH的情形。
示例性的，即使小区#1[DCC1,UCC2/UCC3]中的DCC1的RSRP高于小区#2[DCC5，UCC0/UCC4]中DCC5的RSRP，但如果结合UCC2/UCC3不能满足上行覆盖性能要求，而UCC0/UCC4能满足上行覆盖性能要求，可以优选小区#2作为上报的切换候选目标小区。
在本申请实施例中，通过上报小区或载波信息，能够使得对于小区质量的判断相对准确。进一步地，通过增加对于小区质量的判断的准确性，能够使得终端设备切换到更为符合要求的小区，降低由于终端设备切换到不合适的小区而需要重新切换的概率，从而避免因此而产生的开销和时延。此外，可以先判断第一下行载波是否满足测量上报事件，在第一下行载波满足测量上报事件的情况下，从该第一下行载波关联的所有上行载波确定第一上行载波，即判断该上行载波关联的其他小区的第二下行载波是否大于或等于第一阈值，从而确定第一上行载波，并进一步确定第一上行载波所在的小区为第一小区。简而言之，基于第一下行载波的信号强度和第二下行载波的参考信号强度确定目标切换小区，能够相对准确地切换到符合要求的小区，并在载波测量过程中减少信令开销和降低时延。
图5是本申请实施例提出的一种用于上报小区信息的方法的示意性流程图。在图5中，以第一网络设备为邻基站，第二网络设备为服务基站为例，对图2中的方法进行详细说明。其中，服务基站可以包括灵活小区，也可以不包括灵活小区。邻基站包括至少一个灵活小区。以下，本申请实施例将以终端设备从当前所在的小区切换至邻基站的任一小区为例进行说明。如图5所示，该方法500可以包括步骤S510至步骤S570，其中步骤S550和步骤S570可以用于解释步骤S210和步骤S220。下面详细说明方法500中的各个步骤。
S510，服务基站向终端设备发送配置信息。
具体而言，配置信息可以是邻基站中待测量小区，参考信号配置中的至少一项。该配置信息为服务基站和邻基站通过接口进行信息的传输。在本申请中，服务基站和邻基站之间可以通过现有的X2/Xn接口消息来传递信息，或者通过其他X2/Xn接口消息，例如专门的消息，来传递信息，本申请在此不限定。
若邻基站中的小区为灵活小区，配置信息还包括随机接入资源信息。该随机接入资源信息可以为灵活小区中每个上行载波对应的随机接入资源信息，也可以为灵活小区中频点高于第一下行载波的上行载波对应的随机接入资源信息。示例性地，如图4所示，该随机接入资源信息可以为上行载波对应的随机接入资源信息。例如，小区#1和小区#2为灵活小区，该随机接入资源信息包括UCC2的随机接入资源信息、UCC3的随机接入资源信息、UCC4的随机接入资源信息和UCC0的随机接入资源信息。该随机接入资源信息可以为灵活小区中频点高于第一下行载波的上行载波对应的随机接入资源信息，例如，小区#1中DCC1对应的频点为1.8G，高于DCC1对应频点的上行载波有频点为2.6G的UCC2、频 点为3.9G的UCC3。小区#2中DCC5对应的频点为1.8G，高于DCC5对应频点的上行载波有频点为3.9G的UCC4，则该随机接入资源信息包括UCC2的随机接入资源信息，UCC3的随机接入资源信息和UCC4的随机接入资源信息。
应理解，上文仅为便于理解，列举了服务基站的小区数量和各个小区的上下行载波的频点，但这不应对本申请构成任何限定。本申请对于服务基站的小区数量和各个小区的上下行载波的频点不作限定。
S520，终端设备检测第一下行载波的信号强度，确定第一下行载波的信号强度满足测量上报事件。
其具体的实现方式可以参照S320。这里，为了避免赘述，省略其详细说明。
S530，终端设备向邻基站发送随机接入信号。
具体而言，在步骤S520中，确定第一下行载波的信号强度满足测量上报事件后，确定频点高于该第一下行载波对应频点的上行载波，从而在上行载波上向邻基站发送随机接入信号。更具体地，在上行载波上向邻基站的RRU发送随机接入信号，该随机接入信号包括但不限于前导码。
示例性地，在步骤S520中，或者在步骤S320中，满足测量上报条件的下行载波有DCC1和DCC5，频点高于DCC1的同小区的上行载波有UCC2和UCC3，频点高于DCC5的同小区的上行载波有UCC4。则，终端设备在上行载波UCC2上向RRU#1发送随机接入信号。在上行载波UCC3上向RRU#3发送随机接入信号。在上行载波UCC4上向RRU#2发送随机接入信号。
S540，邻基站向终端设备发送上行载波的信道状态信息。
具体而言，邻基站在至少一个上行载波上接收随机接入信号后，对该随机接入信号进行检测得到上行载波的信道状态信息，并向终端设备发送上行载波的信道状态信息。更具体地，邻基站向终端设备发送RAR，该RAR包括该上行载波的信道状态信息，该随机接入响应消息用于响应随机接入信号。
可选地，该信道状态信息包括RSRP、参考信号强度、路径损耗、信道状态信息(channel state information reference signal，CSI)中至少一项。
可选地，该信道状态信息还包括RSRP的范围、参考信号强度的范围、路径损耗的范围、CSI的范围中至少一项。
可选地，该信道状态指示信息还可以包括上行载波的标识。
可选地，上述在确定第一下行载波的信号强度满足测量上报事件后，确定频点高于该第一下行载波对应频点的上行载波，从而在上行载波上向邻基站发送随机接入信号。其还可以为，从最低频段的载波轮询发送。轮询直到获得至少一个能满足第一条件的上行载波。其中，轮询可以理解为，在随机接入信道(random access channel，RACH)轮询时，对于一个小区中的多个上行载波，从多个上行载波中频点最低的开始进行RACH传输。即从多个上行载波中频点最低的到频点最高的依次传输。
可选地，在轮询过程中，还可以设置发送功率。发送功率可以根据预设满足第一网络设备(例如BBU)接收门限值以及第一网络设备中下行载波路损的功率值设置，从而最小化不必要的爬坡(ramping)造成的开销以及时延。
对于终端设备接收上行载波的信道状态信息，其可以理解为，当信道状态信息为信号 强度时，如果首次传输未被基站监测到，可以遵循已有的爬坡，但要求对所有的上行载波上的信号强度都反馈，开销比较大。当信道状态信息为确定的满足第一条件的激活载波时，如果首次传输未被基站监测到，不能遵循已有的爬坡，否则基站无法确定激活载波。除非基站能通过各种显式或隐式的方式获知终端设备的传输功率。
S550，终端设备确定上行载波的信道状态信息是否大于或等于第二阈值。
S560，终端设备确定第一小区，第一小区为包括信道状态信息大于或等于第二阈值的上行载波以及第一下行载波的小区。或者，终端设备也可以不确定第一小区，仅将信道状态信息大于或等于第二阈值的上行载波和/或第一下行载波确定为需要上报的载波。
具体而言，终端设备检测第一下行载波的信号强度满足测量上报事件后，可以通过确定上行载波确定第一小区。即终端设备接收上行载波的信道状态信息，终端设备根据该信道状态信息直接或间接确定第一上行载波。
可选地，在信道状态信息是信号强度时，终端设备判断上行载波的信道状态指示信息是否大于或等于第二阈值。当上行载波的信道状态指示信息大于或等于第二阈值时，确定该上行载波为第一上行载波，进而确定该第一上行载波所在的灵活小区为第一小区。
可选地，在信道状态指示信息为上行载波的标识时，终端设备可以直接确定该上行载波为第一上行载波。终端设备进而确定该第一上行载波所在的灵活小区为第一小区。
示例性地，在步骤S520中，终端设备确定DCC1对应的信号强度和DCC5对应的信号强度满足测量上报事件，且终端设备在上行载波UCC2上向RRU#1发送随机接入信号，在上行载波UCC3上向RRU#3发送随机接入信号，在上行载波UCC4上向RRU#2发送随机接入信号。以信道状态信息为RSRP，第二阈值为b为例进行说明，终端设备接收UCC2对应的信道状态信息为RSRP#B，UCC3对应的信道状态信息为RSRP#C，UCC4对应的信道状态信息为RSRP#D。若RSRP#B大于b，RSRP#C和RSRP#D均小于b，终端设备可以确定UCC2为需要进行业务传输的上行载波(第一上行载波)，进一步终端设备可以确定UCC2所在的灵活小区为第一小区，即小区#1为第一小区。
可选地，第二阈值可以为网络设备配置，例如，第一阈值可以为服务基站通过信令配置，该信令包括但不限于RRC信令。再例如，第一阈值可以为邻基站通过广播消息配置，包括但不限于SIB发送的广播消息。
S570，终端设备向服务基站发送第一信息。
其具体的实现方式可以参照S350。这里，为了避免赘述，省略其详细说明。
在上述方案中，先判断第一下行载波是否满足测量上报事件，在第一下行载波满足测量上报事件的情况下，判断该上行载波对应的信道状态信息是否大于或等于第二阈值，从而确定第一上行载波，并进一步确定第一上行载波所在的小区为第一小区。简而言之，基于第一下行载波的信号强度和至少一个上行载波的信道状态信息确定目标切换小区，能够相对准确地切换到符合要求的小区，并在载波测量过程中减少信令开销和降低时延。
图6是本申请实施例提出的一种用于上报小区信息的方法的示意性流程图。在图6中，以第一网络设备为邻基站，第二网络设备为服务基站为例，对图2中的方法进行详细说明。其中，服务基站可以包括灵活小区，也可以不包括灵活小区。邻基站包括至少一个灵活小区。以下，本申请实施例将以终端设备从当前所在的小区切换至邻基站的任一小区为例进行说明。如图6所示，该方法600可以包括步骤S610至步骤S612。下面详细说明方法600 中的各个步骤。
S610，服务基站向终端设备发送配置信息。
具体而言，配置信息可以是邻基站中待测量小区，参考信号配置中的至少一项。该配置信息为服务基站和邻基站通过接口进行信息的传输。在本申请中，服务基站和邻基站之间可以通过现有的X2/Xn接口消息来传递信息，或者通过其他X2/Xn接口消息，例如专门的消息，来传递信息，本申请在此不限定。
若邻基站中的小区为灵活小区，配置信息还包括第一信号资源信息。该第一信号资源信息可以为灵活小区中每个上行载波对应的第一信号资源信息，也可以为灵活小区中频点高于第一下行载波的上行载波对应的第一信号资源信息。
示例性地，如图4所示，该第一信号资源信息可以为每个上行载波对应的第一信号资源信息。例如，小区#1和小区#2为灵活小区，该第一信号资源信息包括UCC2的第一信号资源信息、UCC3的第一信号资源信息、UCC4的第一信号资源信息和UCC0的第一信号资源信息。该第一信号资源信息可以为灵活小区中频点高于第一下行载波的上行载波对应的第一信号资源信息。例如，小区#1中DCC1对应的频点为1.8G，高于DCC1对应频点的上行载波有频点为2.6G的UCC2、频点为3.9G的UCC3。小区#2中DCC5对应的频点为1.8G，高于DCC5对应频点的上行载波有频点为3.9G的UCC4，则该第一信号资源信息包括UCC2的第一信号资源信息，UCC3的第一信号资源信息和UCC4的第一信号资源信息。
应理解，上文仅为便于理解，列举了服务基站的小区数量和各个小区的上下行载波的频点，但这不应对本申请构成任何限定。本申请对于服务基站的小区数量和各个小区的上下行载波的频点不作限定。
可选地，第一信号可以为前端带有CP的序列或RIM信号。
示例性地，第一信号可以为SRS，CSI-RS、DMRS中至少一项，其还可以为一个新定义的信号。承载第一信号的资源在时域上包括M个OFDM符号，每个符号承载的是相同的第一信号。且在M个OFDM符号之前(或者最前端)添加X个CP，其中，M为正整数，X≥1。例如该新定义的信号可以为类似RIM信号。S602，邻基站在第一下行载波上向终端设备发送参考信号，即第一下行载波上的参考信号。
S602，终端设备检测第一下行载波的信号强度，确定第一下行载波的信号强度满足测量上报事件。
其具体的实现方式可以参照S320。这里，为了避免赘述，省略其详细说明。
可选地，S603，服务基站向邻基站发送配置信息和触发信息。
具体而言，服务基站和邻基站均要知道配置信息和触发信息。在第一种可能的实现方式中，若服务基站向终端设备发送配置信息，以及向终端发送触发信息，服务基站也要向邻基站发送配置信息和触发信息。在第二种可能的实现方式中，若邻基站向终端设备发送配置信息，以及向终端发送触发信息，邻基站也要向服务基站发送配置信息和触发信息。在第三种可能实现方式中，若服务基站向终端设备发送配置信息，邻基站向终端设备发送触发信息，服务基站要向邻基站发送配置信息，以及邻基站要向服务基站发送触发信息。在第四种可能实现方式中，若服务基站向终端设备发送触发信息，邻基站向终端设备发送配置信息，服务基站要向邻基站发送触发信息，以及邻基站要向服务基站发送配置信息。
需要注意的，当服务基站向邻基站发送配置信息和触发信息，或邻基站向服务基站发送配置信息和触发信息，配置信息和触发信息可以在同一条消息中发送，也可以在不同消息中发送，在不同消息发送时，配置信息和触发信息的发送顺序本申请实施例不过多限定。
需要注意的，步骤S603和步骤S601、步骤S602之间并没有严格的顺序关系。即S603可以在S601之前执行，也可以在S601之后执行，或者同时执行等。本申请实施例对三者之间的顺序不做任何限定。
可选地，S604，服务基站向终端设备发送触发信息。
具体而言，触发信息可以为服务基站向终端设备发送，也可以为，邻基站向终端设备发送。该触发信息用于指示终端设备发送第一信号，也可以理解为，终端设备接收触发信息后，可以发送第一信号，即：
S605，终端设备向服务基站发送第一信号；和/或，终端设备向邻基站发送第一信号。
当终端设备在上行载波上向服务基站发送第一信号时，邻基站也可以检测到终端设备在上行载波上发送的第一信号。在这种情况下，可以为服务基站对上行载波上的第一信号进行检测，获取上行载波的信道状态信息，并将该上行载波的信道状态信息向终端设备发送。也可以为邻基站对上行载波上的第一信号进行检测，获取上行载波的信道状态信息，并将该信道状态信息发送至服务基站，例如步骤S607，服务基站向终端设备发送至终端设备，例如步骤S608。也可以为邻基站对上行载波上的第一信号进行检测，获取上行载波的信道状态信息，并将该信道状态信息发送至终端设备。
在一种可能实现的方式中，还可能存在，在发送第一信号之前，终端设备向邻基站发送随机接入信号，并从邻基站接收RAR，该RAR包括第一信号的指示信息。终端设备在至少一个上行载波上向第二基站发送第一信号，其中，第一信号为SRS。
在一种可能的实现方式中，多个上行SRS中，会有一个第一上行信号，邻基站基于该第一上行信号测量，并向服务基站反馈测量所得的强度。可选地，每Y个上行信号中，前Y-1个为SRS，第Y个为第一上行信号。第一网络设备向终端设备配置Y的值。其中，Y为整数且Y≥2。
S609，终端设备确定上行载波的信道状态信息是否大于或等于第二阈值。
S610，终端设备确定第一小区，第一小区为包括信道状态信息大于或等于第二阈值的上行载波以及第一下行载波的小区。或者，终端设备也可以不确定第一小区，仅将信道状态信息大于或等于第二阈值的上行载波和/或第一下行载波确定为需要上报的载波。
S611，终端设备向服务基站发送第一信息。
其具体的实现方式可以参照S550至S570。这里，为了避免赘述，省略其详细说明。
在上述方案中，终端设备在上行载波上向第一网络设备或第二网络设备发送第一信号，该第一信号既可以被邻基站检测，也可以被用于服务基站检测。当用于邻基站检测时，可以不受定时提前(timing advance，TA)不准所导致/所造成的影响，即基站确定信道状态信息时可以不受TA不准造成的估计偏差。当用于服务基站检测时，可以使得服务基站基于此实现获取信道状态信息的目的。因此不造成额外的系统开销。
