如图1所示，本公开实施例提供的一种确定辅小区的方法可应用于无线通信系统100，该无线通信系统可以包括但不限于网络设备101和用户设备102。用户设备102被配置为支持载波聚合，用户设备102可连接至网络设备101的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景，也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频 分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th-Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示用户设备102可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备102可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备101进行通信(如无线通信)，并接受网络设备101提供的网络服务，这里的网络设备101包括但不限于图示基站。
其中，用户设备102可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备101可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备具体可包括基站(base station，BS)设备，或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备可以是可穿戴设备或车载设备。网络设备也可以是具有通信模块的通信芯片。
比如，网络设备101包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA系统中的节点B(node B，NB)、CRAN系统下的无线控制器、基站控制器(basestation controller，BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
考虑到应用提前测量报告(Early Measurement Report，EMR)后用户设备可以在空闲 态(idle)或非激活态(inactive)下根据网络设备配置的载波测量信息进行测量和上报。通信协议要求，在FR2(Frequency Range 2)场景下检测和测量一个FR2载波的时延非常长，再考虑到载波数扩展因子，时延将进一步增加。发明人在研究中发现，如此长的时延要求可能会导致用户设备上报的EMR的测量结果不可信。
另外，发明人在研究中还发现，当用户设备在空闲态(idle)或非激活态(inactive)完成EMR后，在接入服务小区的过程中启动无线资源控制(Radio Resource Control，RRC)建立请求的时长不确定，并且，完成RRC连接建立的时间较长，还会导致用户设备上报的EMR的测量结果过期而变得不可信。根据EMR的测量报告确定多链接中的辅小区，可能会导致确定出的辅小区的信号质量较差，使多链接中与辅小区之间的链接的链路性能不佳，影响多链接的链路质量。
因此发明人在研究中发现，用户设备在在空闲态(idle)或非激活态(inactive)完成EMR后接入服务小区，在接入服务小区的过程中有必要对EMR中测量过的部分或全部载波再次进行测量，以防止EMR的测量结果已过期，此再次进行的测量可以认为是对EMR的一种增强测量，此增强测量的测量结果比EMR的测量结果更准确，从而根据增强测量的测量结果确定多链接中的辅小区，可以确定出信号质量较好的辅小区，保证多链接中与辅小区之间的链接的链路性能，提高多链接的整体链路质量。
本公开实施例提供了一种确定辅小区的方法，图2是根据一示例性实施例示出的一种确定辅小区的方法的流程图，如图2所示，该方法包括步骤S201～S207，具体的：
S201，网络设备向用户设备发送测量配置信息，所述测量配置信息用于配置N个待测载波。
在一些可能的实施方式中，所述N个待测载波包括N个NR载波，或者包括N个LTE载波，或者包括多个NR载波和多个LTE载波，此多个NR载波的数量和多个LTE载波的数量之和为N。
S202，用户设备在处于非连接态时对N个待测载波进行第一测量，获得第一测量结果。
在一些可能的实施方式中，非连接态为空闲态(idle)或非激活态(inactive)。
S203，用户设备在接入所述网络设备下的服务小区的过程中，响应于接入服务小区事件对所述N个待测载波中的M个待测载波进行第二测量，获得第二测量结果。

在一些可能的实施方式中，接入服务小区事件为以下中的一种：
向所述服务小区发送随机接入请求、
接收所述服务小区的寻呼消息、
向所述服务小区发送无线链路连接请求。
在一些可能的实施方式中，用户设备在接入所述网络设备下的服务小区的过程中，响应于接入服务小区事件对所述N个待测载波进行第二测量，获得第二测量结果。
在一些可能的实施方式中，所述第二测量为基于层1的参考信号接收功率(L1_RSRP)的测量，或者为基于层3的参考信号接收功率(L3_RSRP)的测量。
S204，用户设备向网络设备发送所述第二测量结果。
S205，网络设备根据所述第二测量结果确定多链接中的辅小区。
S206，网络设备向用户设备发送用于指示辅小区的指示信息。
S207，用户设备根据服务小区和辅小区建立多链接。
本公开实施例中，用户设备在在空闲态(idle)或非激活态(inactive)完成EMR后接入服务小区，在接入服务小区的过程中对EMR中测量过的全部载波再次进行测量，以防止EMR的测量结果已过期，此再次进行的测量可以认为是对EMR的一种增强测量，此增强测量的测量结果比EMR的测量结果更准确，从而根据增强测量的测量结果确定多链接中的辅小区，可以确定出信号质量较好的辅小区，保证多链接中与辅小区之间的链接的链路性能，提高多链接的整体链路质量。
在一些可能的实施方式中，S203中用户设备在接入所述网络设备下的服务小区的过程中，响应于接入服务小区事件对所述N个待测载波中设定的M个待测载波进行第二测量，获得第二测量结果。例如：M小于N，设定的M个待测载波是用户设备根据约议约定获知的，或者从网络设备发送的指示信息中获知的，或者是默认的。
在一些可能的实施方式中，在S202之前，用户设备向网络设备发送用户设备能力，所述用户设备能力用于指示所述用户设备是否支持针对第二测量的时延要求增强。
所述针对第二测量的时延要求增强包括：针对层1测量的时延要求增强和/或针对层1测量的时延要求增强。
在一些可能的实施方式中，支持针对层1测量的时延要求增强是指支持针对层1测量的时延缩短。在一示例中，支持针对层1测量的时延要求增强是指支持针对层1测量的时延小于约定时长，此约定时长小于已有协议中定义的针对层1测量的时延。已有协议可以是R16或R17协议。
支持针对层3测量的时延要求增强是指支持针对层3测量的时延缩短。在一示例中，支持针对层3测量的时延要求增强是指支持针对层3测量的时延小于约定时长，此约定时 长小于已有协议中定义的针对层3测量的时延。
在一示例中，UE在空闲态或非激活态对N个待测载波执行EMR测量并得到第一测量结果，当UE向网络发起RRC连接建立请求后，需要对N个待测载波中的M个待测载波执行L1_RSRP测量，如果UE在之前的L1_RSRP测量期间已经执行过接收波束的确认过程，则UE在执行此次的L1_RSRP测量时不需要执行接收波束扫描(Rxbeamsweeping)，或者需要执行接收波束扫描但扫描的次数可以减小，例如不需要扫描8次，只需要扫描4次或2次就能确定最佳接收波束，从而UE执行L1_RSRP测量的时延可以缩短。在此情况下，UE在之前的L1_RSRP测量期间已经执行过接收波束的确认过程时，UE向网络设备发送用户设备能力，所述用户设备能力用于指示所述UE支持针对L1_RSRP测量的时延要求增强。
在一示例中，UE在空闲态或非激活态对N个待测载波执行EMR测量并得到第一测量结果，当UE向网络发起RRC连接建立请求后，需要对N个待测载波中的M个待测载波执行L3_RSRP测量，如果UE具备同时使用多个接收波束接收下行信号的能力(例如同时使用2个接收波束接收下行信号的能力)，则UE在执行此次的L1_RSRP测量时需要执行接收波束扫描但扫描的次数可以减小，例如不需要扫描8次，只需要扫描4次或2次就能确定最佳接收波束，从而UE执行L1_RSRP测量的时延可以缩短。在此情况下，UE具备同时使用多个接收波束接收下行信号的能力时，UE向网络设备发送用户设备能力，所述用户设备能力用于指示所述UE支持针对L3_RSRP测量的时延要求增强。
本公开实施例提供了一种建立多链接的方法，图3是根据一示例性实施例示出的一种建立多链接的方法的流程图，如图3所示，该方法包括步骤S301～S308，具体的：
S301，网络设备向用户设备发送测量配置信息，所述测量配置信息用于配置N个待测载波。
在一些可能的实施方式中，所述N个待测载波包括N个NR载波，或者包括N个LTE载波，或者包括多个NR载波和多个LTE载波，此多个NR载波的数量和多个LTE载波的数量之和为N。
S302，用户设备在处于非连接态时对N个待测载波进行第一测量，获得第一测量结果。
在一些可能的实施方式中，非连接态为空闲态(idle)或非激活态(inactive)。
S303，用户设备确定所述N个待测载波中的M个待测载波。其中，M和N均为正整数，M小于或等于N。
S304，用户设备在接入所述网络设备下的服务小区的过程中，响应于接入服务小区事 件对所述M个待测载波进行第二测量，获得第二测量结果。
在一些可能的实施方式中，所述第二测量为基于层1的参考信号接收功率(L1_RSRP)的测量，或者为基于层3的参考信号接收功率(L3_RSRP)的测量。
在一些可能的实施方式中，接入服务小区事件为以下中的一种：
向所述服务小区发送随机接入请求、
接收所述服务小区的寻呼消息、
向所述服务小区发送无线链路连接请求。
S305，用户设备向网络设备发送所述第二测量结果。
S306，网络设备根据所述第二测量结果确定多链接中的辅小区。
S307，网络设备向用户设备发送用于指示辅小区的指示信息。
S308，用户设备根据服务小区和辅小区建立多链接。
本公开实施例中，用户设备在空闲态(idle)或非激活态(inactive)完成EMR后接入服务小区，在接入服务小区的过程中对EMR中测量过的载波中的部分载波再次进行测量，以防止EMR的测量结果已过期，此再次进行的测量可以认为是对EMR的一种增强测量，此增强测量的测量结果比EMR的测量结果更准确，从而根据增强测量的测量结果确定多链接中的辅小区，可以确定出信号质量较好的辅小区，保证多链接中与辅小区之间的链接的链路性能，提高多链接的整体链路质量，另外，通过对EMR中测量过的载波中的部分载波再次测量，相比于对EMR中测量过的所有载波进行测量，可以节省用户设备的测量能力，进一步缩短建立多链接的时长。
下面详细说明S303中用户设备确定所述N个待测载波中的M个待测载波的方式。可以通过以下三种方式实现。
方式一
S301中的测量配置信息还用于配置选择参数，所述选择参数为有效时长阈值。
S303中用户设备根据所述有效时长阈值和与所述有效时长阈值对应的选择方式从所述N个待测载波中选择所述M个待测载波。
关于有效时长阈值可以有两种情况，第一种情况中，有效时长阈值是一个用于N个待测载波中所有待测载波的第一阈值，第二种情况中，有效时长阈值是多个第二阈值，每个第二阈值用于不同的一个或多个待测载波。
下面详细说明此两种情况。
第一种情况：
所述有效时长阈值为第一阈值，所述第一阈值对应于所述N个待测载波。
所述第一阈值对应的选择方式为：在设定时长大于所述第一阈值时，确定所述M等于所述N，选择所述N个待测载波，其中，所述设定时长为第一时刻和第二时刻之间的时长(即第一时刻距离第二时刻的时长)，第一时刻T1为完成所述第一测量的时刻，第二时刻T2为所述接入服务小区事件的发生时刻。
在一示例中，用户设备在空闲态或者非激活态完成EMR测量的时刻为T1，用户设备向网络设备发送RRC连接请求的时刻为T2，如果T2和T1之间的时长(即T1距离T2的时长)大于或等于第一阈值(例如第一阈值为5毫秒)，则选择所述N个待测载波，如果T2和T1之间的时长(即T1距离T2的时长)小于第一阈值，则无需从所述N个待测载波中选择出任一待测载波。
即相应的，如果T2和T1之间的时长(即T1距离T2的时长)大于或等于第一阈值(例如第一阈值为5毫秒)，则需要对所述N个待测载波均进行增强测量，如果T2和T1之间的时长(即T1距离T2的时长)小于第一阈值，则无需对所述N个待测载波中任一待测载波进行增强测量。
在另一示例中，用户设备在空闲态或者非激活态完成EMR测量后，启动定时器，定时器的定时时长为第一阈值(例如第一阈值为5毫秒)，用户设备向网络设备发送RRC连接请求时，如果定时器已超时，则选择所述N个待测载波；如果定时器未超时，则无需从所述N个待测载波中选择出任一待测载波。
即相应的，用户设备向网络设备发送RRC连接请求时，如果定时器已超时，则需要对所述N个待测载波均进行增强测量，如果定时器未超时，则无需从所述N个待测载波中选择出任一待测载波。
第二种情况：
所述有效时长阈值为K个第二阈值，每个第二阈值对应于所述N个待测载波中的至少一个待测载波，所述K为正整数，K小于或等于N。
所述K个第二阈值对应的选择方式为：选择出的待测载波的第二阈值小于设定时长，其中，所述设定时长为第一时刻和第二时刻之间的时长(即第一时刻距离第二时刻的时长)，所述第一时刻T1为完成所述第一测量的时刻，所述第二时刻T2为所述接入服务小区事件的发生时刻。
需要说明的是，网络设备发送的测量配置信息中除了指示K个第二阈值外，还指示每个第二阈值与至少一个待测载波的对应关系。例如：测量配置信息可以以信息对的方式进 行指示，每个信息对中包括第一信息和第二信息，第一信息用于指示第二阈值，第二信息用于指示与所述第二阈值对应的待测载波(可以是一个或多个)。
在一示例中：
N的值为10，K的值为10，则用户设备在EMR测量中测量了10个待测载波，并且从网络设备获知了10个第二阈值。第1个第二阈值即Thre_1对应于第1个待测载波，第2个第二阈值即Thre_2对应于第2个待测载波，以此类推，第10个第二阈值即Thre_10对应于第10个待测载波。
用户设备在空闲态或者非激活态完成EMR测量的时刻为T1，用户设备向网络设备发送RRC连接请求的时刻为T2，如果T2和T1之间的时长(即T1距离T2的时长)大于或等于10个第二阈值中哪些第二阈值，则选择这些第二阈值一一对应的待测载波。
T2和T1之间的时长(即T1距离T2的时长)大于第1个第二阈值即Thre_1和第2个第二阈值即Thre_2，T2和T1之间的时长(即T1距离T2的时长)小于其它的8个第二阈值中任一个，则选择出第1个第二阈值即Thre_1对应的第1待测载波和第2个第二阈值即Thre_2对应的第2待测载波，而不选择其它的8个待测载波。即需要对第1待测载波和第2待测载波进行增强测量，而无需对其它的8个待测载波进行增强测量。
方式二
S301中的所述测量配置信息还用于配置选择参数，所述选择参数包括信号强度阈值。
S303中根据所述信号强度阈值和与所述信号强度阈值对应的选择方式从所述N个待测载波中选择所述M个待测载波。
关于信号强度阈值可以有两种情况，第一种情况中，信号强度阈值是一个用于N个待测载波中所有待测载波的第三阈值，第二种情况中，有效时长阈值是多个第四阈值，每个第四阈值用于不同的一个或多个待测载波。
下面详细说明此两种情况。
第一种情况：
所述信号强度阈值为第三阈值，所述第三阈值对应于所述N个待测载波。
所述第三阈值对应的选择方式为：选择所述第一测量结果中信号强度值大于所述第三阈值的待测载波。
具体的：用户设备在空闲态或者非激活态完成EMR测量后，获得第一测量结果，第一测量结果中包括对所述N个待测载波中每个待测载波测量得到的信号强度值，选择所述第一测量结果中信号强度值大于所述第三阈值的待测载波。
在此第一种情况下，选择信号强度值较大的待测载波进行增强测量，在EMR测量结果的已过期的时长较短即可信度较高时，可以准确的选择到信号质量较好的辅小区。
在一示例中：
N的值为10，则用户设备在空闲态或者非激活态时执行EMR测量时需测量10个待测载波，获得第一测量结果，第一测量结果中包括对所述10个待测载波中每个待测载波测量得到的信号强度值，如果对第1待测载波测量得到的信号强度值、对第2待测载波测量得到的信号强度值和对第3待测载波测量得到的信号强度值均大于第三阈值，对其它的8个待测载波测量得到的信号强度值均小于第三阈值，则选择第1待测载波、第2待测载波和第3待测载波，而不选择其它的8个待测载波。
即需要对第1待测载波、第2待测载波和第3待测载波进行增强测量，而无需对其它的7个待测载波进行增强测量。
第二种情况：
所述信号强度阈值为L个第四阈值，每个第四阈值对应于所述N个待测载波中的至少一个待测载波，所述L为正整数，L小于或等于N；
所述L个第四阈值对应的选择方式为：选择所述第一测量结果中信号强度值大于或等于相应的第四阈值的待测载波，或者，选择所述第一测量结果中信号强度值小于相应的第四阈值的待测载波。
需要说明的是，网络设备发送的测量配置信息中除了指示L个第四阈值外，还指示每个第四阈值与至少一个待测载波的对应关系。例如：测量配置信息可以以信息对的方式进行指示，每个信息对中包括第一信息和第二信息，第一信息用于指示第四阈值，第二信息用于指示与所述第四阈值对应的待测载波(可以是一个或多个)。
在此第二种情况下，选择信号强度值较大的待测载波进行增强测量，在EMR测量结果的已过期的时长较短即可信度较高时，可以准确的选择到信号质量较好的辅小区。选择信号强度值较小的待测载波进行增强测量，在EMR测量结果的已过期的时长较长即可信度较低时，可以节省用户设备的测量能力。
在一示例中：
N的值为10，L的值为10，则用户设备在空闲态或者非激活态时执行EMR测量时需测量10个待测载波，并且从网络设备获知了10个第四阈值。每个待测载波对应于一个第四阈值。
用户设备在空闲态或者非激活态完成EMR测量后，获得第一测量结果，第一测量结 果中包括对所述10个待测载波中每个待测载波测量得到的信号强度值，如果对第1待测载波测量得到的信号强度值大于第1待测载波对应的第四阈值，对第2待测载波测量得到的信号强度值大于第2待测载波对应的第四阈值，对其它的任一待测载波测量得到的信号强度值均小于相应的第四阈值，则选择第1待测载波和第2待测载波，而不选择其它的8个待测载波。
在另一示例中：
N的值为10，L的值为3，则用户设备在空闲态或者非激活态时执行EMR测量时需测量10个待测载波，并且从网络设备获知了3个第四阈值。第1至4个待测载波对应于第1个第四阈值，第5至8个待测载波对应于第2个第四阈值，第9至10个待测载波对应于第3个第四阈值。
用户设备在空闲态或者非激活态完成EMR测量后，获得第一测量结果，第一测量结果中包括对所述10个待测载波中每个待测载波测量得到的信号强度值，如果对第1待测载波测量得到的信号强度值大于第1待测载波对应的第四阈值，对其它的任一待测载波测量得到的信号强度值均小于相应的第四阈值，则选择第1待测载波，而不选择其它的9个待测载波。
方式三

S303中根据所述优先级和与所述优先级对应的选择方式从所述N个待测载波中选择所述M个待测载波。
关于优先级可以有两种情况，第一种情况中，优先级为多个组优先级，每个组包括所述N个待测载波中至少一待测载波，每个组对应于一个组优先级。第二种情况中，优先级为多个载波优先级，每个载波优先级对应于一个待测载波。
下面详细说明此两种情况。
第一种情况：
所述优先级为多个组优先级，每个组优先级对应于一个分组，每个分组包括所述N个待测载波中至少一待测载波；
所述多个组优先级对应的选择方式为：选择出的待测载波为设定组中的待测载波，所述设定组的组优先级大于第一设定优先级。
需要说明的是，网络设备发送的测量配置信息中除了指示多个组优先级外，还指示每个组优先级与分组的对应关系，以及分组与待测载波的对应关系(即分组中包括哪些待测 载波)。例如：测量配置信息可以以信息组的方式进行指示，每个信息组中包括第一信息、第二信息和第三信息，第一信息用于指示组优先级，第二信息用于指示与所述组优先级对应的分组，第三信息用于指示所述分组中包括的待测载波(可以是一个或多个)。
用户设备根据约议约定获知第一设定优先级，或者从网络设备发送的指示信息中获知第一设定优先级，或者第一设定优先级是默认的。
在一示例中：
N的值为10，组优先级共有3个，分别对应于3个分组。
用户设备在空闲态或者非激活态时执行EMR测量时需测量10个待测载波，并且从网络设备获知了3个组优先级。
第一个分组的组优先级为H，第一个分组包括第1至第3个待测载波。第二个分组的组优先级为M，第二个分组包括第4至第8个待测载波。第三个分组的组优先级为L，第三个分组包括第9至第10个待测载波。组优先级从高到低依次为：H，M，L。
用户设备在空闲态或者非激活态完成EMR测量后，在第一设定优先级为M时，根据3个组优先级选择组优先级大于M的组为第一个分组，选择第一个分组中所有的待测载波，最终选择到的待测载波为第1至第3个待测载波。
第二种情况：
所述优先级为多个载波优先级，每个载波优先级对应于一个待测载波；
所述多个载波优先级对应的选择方式为：选择出的待测载波的载波优先级大于第二设定优先级。
用户设备根据约议约定获知第二设定优先级，或者从网络设备发送的指示信息中获知第二设定优先级，或者第二设定优先级是默认的。
需要说明的是，网络设备发送的测量配置信息中除了指示载波优先级外，还指示每个载波优先级与待测载波的对应关系。例如：测量配置信息可以以信息对的方式进行指示，每个信息对中包括第一信息和第二信息，第一信息用于指示待测载波，第二信息用于指示所述待测载波的载波优先级。
在一示例中：
N的值为10，载波优先级共有4个，从高到低依次为：A1，A2，A3和A4。
用户设备在空闲态或者非激活态时执行EMR测量时需测量10个待测载波，并且从网络设备获知了每个待测载波的载波优先级。
用户设备在空闲态或者非激活态完成EMR测量后，在第一设定优先级为A3时，选择 载波优先级为A1或A2的待测载波。

工业实用性
用户设备在在空闲态(idle)或非激活态(inactive)完成EMR后接入服务小区，在接入服务小区的过程中对EMR中测量过的部分或全部载波再次进行测量，以防止EMR的测量结果已过期，此再次进行的测量可以认为是对EMR的一种增强测量，此增强测量的测量结果比EMR的测量结果更准确，从而根据增强测量的测量结果确定多链接中的辅小区，可以确定出信号质量较好的辅小区，保证多链接中与辅小区之间的链接的链路性能，提高多链接的整体链路质量。
