具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是根据本公开一个实施例示出的一种无线链路状态确定方法的示意流程图。本实施例所示的无线链路状态确定方法可以适用于用户设备，例如手机、平板电脑、可穿戴设备等。如图1所示，所述无线链路状态确定方法可以包括以下步骤。
在步骤S1中，确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败。
在一个实施例中，针对增补上行载波和非增补上行载波，可以分别确定是否存在无线链路失败(Radio Link Failure，简称RLF)。
例如对于增补上行载波，可以通过监听增补上行载波上失同步的数目和同步的数目来确定增补上行载波是否存在无线链路失败；也可以通过判断在增补上行载波上发起的随机接入是否失败确定增补上行载波是否存在无线链路失败。
例如对于非增补上行载波，可以通过监听非增补上行载波上失同步的数目和同步的数目来确定非增补上行载波是否存在无线链路失败；也可以通过判断在非增补上行载波上发起的随机接入是否失败确定非增补上行载波是否存在无线链路失败。
关于上述监听失同步的数目和同步的数目确定是否存在无线链路失败的方式，和通过判断随机接入是否失败确定是否存在无线链路失败的方式，在后续实施例中进行详细说明。
在一个实施例中，增补上行载波对应频段的下限值，可以小于非增补上行载波对应频段的下限值，且增补上行载波对应频段的上限值，可以小于非增补上行载波对应频段的上限值。
在步骤S2中，若所述增补上行载波存在无线链路失败，和/或所述非增补上行载波存在无线链路失败，确定所述小区存在无线链路失败，发起连接重建流程和/或向基站传输无线链路失败的信息。
在一个实施例中，在增补上行载波存在无线链路失败的情况下，可以确定所述被配置了增补上行载波的小区存在无线链路失败。
在一个实施例中，在非增补上行载波存在无线链路失败的情况下，可以确定所述被配置了增补上行载波的小区存在无线链路失败。
在一个实施例中，在增补上行载波存在无线链路失败，且非增补上行载波存在无线链路失败的情况下，可以确定所述被配置了增补上行载波的小区存在无线链路失败。
在一个实施例中，一般情况下，在确定小区存在无线链路失败的情况下，可以根据小区是主小区(PCell)还是主辅小区(PSCell)，来确定发起连接重建流程，或者向基站传输无线链路失败的信息，或者既发起连接重建流程，又向基站传输无线链路失败的信息。
基于图1所示的实施例，可以针对被配置了增补上行载波的小区，分别确定增补上行载波是否存在无线链路失败，以及确定非增补上行载波是否存在无线链路失败，并综合增补上行载波的确定结果和非增补上行载波的确定结果，确定被配置了增补上行载波的小区是否存在无线链路失败，进而保证用户设备可以准确地确定被配置了增补上行载波的小区是否存在无线链路失败，以便做出适当处理，保证良好的通信效果。
图2是根据本公开一个实施例示出的一种确定无线链路失败的示意流程图。如图2所示，在图1所示实施例的基础上，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败包括：
在步骤S11中，在所述增补上行载波上和/或所述非增补上行载波上进行无线链路监听(Radio Link Monitoring，简称RLM)；
在步骤S12中，若在所述增补上行载波上连续失同步的数目大于或等于第一数目，启动第一定时器，在所述第一定时器超时前，若在所述增补上行载波上连续同步的数目小于第二数目，确定所述增补上行载波存在无线链路失败；和/或
在步骤S13中，若在所述非增补上行载波上连续失同步的数目大于或等于第三数目，启动第二定时器，在所述第二定时器超时前，若在所述非增补上行载波上连续同步的数目小于第四数目，确定所述非增补上行载波存在无线链路失败。
在一个实施例中，第一数目、第二数目、第三数目和第四数目的关系可以根据需要进行设置，例如可以设置其中两个数目相同，也可以设置四个数目各不相同。
在一个实施例中，在增补上行载波上和/或非增补上行载波上进行无线链路监听时。
以增补上行载波为例，物理层可以指示在增补上行载波上监听到的连续失同步(out-of-syn)的数目OOS1，若OOS1大于或等于第一数目，可以启动定时器进行计时。在定时器计时期间，继续对增补上行载波的监听，物理层可以指示在增补上行载波上间监听到的连续同步(in-sync)的数目IS1，若在定时器计时超时前，IS1的数目小于第二数目，则确定增补上行载波存在无线链路失败。
以非增补上行载波为例，物理层可以指示在非增补上行载波上监听到的连续失同步(out-of-syn)的数目OOS2，若OOS2大于或等于第三数目，可以启动定时器进行计时。在定时器计时期间，继续对非增补上行载波的监听，物理层可以指示在非增 补上行载波上间监听到的连续同步(in-sync)的数目IS2，若在定时器计时超时前，IS2的数目小于第四数目，则确定非增补上行载波存在无线链路失败。
图3是根据本公开一个实施例示出的另一种确定无线链路失败的示意流程图。如图3所示，在图2所示实施例的基础上，所述在所述增补上行载波上和/或所述非增补上行载波上进行无线链路监听包括：
在步骤S111中，确定所述增补上行载波和非增补上行载波中，被配置了物理上行控制信道的载波；
在步骤S112中，在所述被配置了物理上行控制信道的载波上进行无线链路监听。
在一个实施例中，可以仅对增补上行载波和非增补上行载波中，被配置了物理上行控制信道(PUCCH，Physical Uplink Control CHannel)的载波上进行监听。
由于用户设备在被配置了物理上行控制信道的载波不存在无线链路失败时，即可通过物理上行控制信道传输ACK/NACK(确认和非确认)，CQI(信道质量指示)，PMI(预编码矩阵指示)和RI(秩指示)等信息，从而在一定程度上进行通信。
因此可以仅对被配置了物理上行控制信道的载波进行监听，确定被配置了物理上行控制信道的载波是否存在无线链路失败，并在被配置了物理上行控制信道的载波存在无线链路失败的情况下进行处理(例如执行步骤S2)，即可进行通信，从而无需对未配置了物理上行控制信道的载波进行监听，减少监听操作对用户设备的资源占用。
图4是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图4所示，在图2所示实施例的基础上，所述在所述增补上行载波上和/或所述非增补上行载波上进行无线链路监听包括：
在步骤S113中，确定所述增补上行载波和非增补上行载波中，被配置了物理上行控制信道和物理上行共享信道的载波；
在步骤S114中，在所述被配置了物理上行控制信道和物理上行共享信道的载波上进行无线链路监听。
在一个实施例中，可以仅对增补上行载波和非增补上行载波中，被配置了物理上行控制信道和物理上行共享信道(PUSCH，Physical Uplink Shared CHannel)的载波上进行监听。
由于用户设备在被配置了物理上行控制信道和物理上行共享信道的载波不存在无线链路失败时，即可通过物理上行控制信道传输ACK/NACK，CQI，PMI和RI等信息，以及通过物理上行共享信道传输数据，从而正常进行通信。
因此可以仅对被配置了物理上行控制信道和物理上行共享信道的载波进行监听，确定被配置了物理上行控制信道和物理上行共享信道的载波是否存在无线链路失败，并在被配置了物理上行控制信道和物理上行共享信道的载波存在无线链路失败的情况下进行处理(例如执行步骤S2)，即可保证正常通信，从而无需对未配置了物理上行控制信道和物理上行共享信道的载波进行监听，减少监听操作对用户设备的资源占用。
图5是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图5所示，在图2所示实施例的基础上，若在所述增补上行载波上连续同步的数目小于第二数目，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败还包括：
在步骤S14中，确定所述增补上行载波是否被配置了物理上行控制信道；
在步骤S15中，若被配置了物理上行控制信道，确定所述增补上行载波存在无线链路失败；和/或
若在所述非增补上行载波上连续同步的数目小于第四数目，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败还包括：
在步骤S16中，确定所述非增补上行载波是否被配置了物理上行控制信道；
在步骤S17中，若被配置了物理上行控制信道，确定所述非增补上行载波存在无线链路失败。
在一个实施例中，基于图2所示的实施例，针对增补上行载波，若连续同步的数目小于第二数目，可以进一步确定增补上行载波是否被配置了物理上行控制信道，并在增补上行载波被配置了物理上行控制信道的情况下，才确定增补上行载波存在无线链路失败。由于仅被配置了物理上行控制信道的载波，在存在无线链路失败的情况下，才会对用户设备的通信造成较大影响，因此对于未被配置物理上行控制信道的增补上行载波，即使连续同步的数目小于第二数目，也可以不进行处理(例如不执行步骤S2)，从而减少对用户设备的资源占用。
在一个实施例中，基于图2所示的实施例，针对非增补上行载波，若连续同步的数目小于第四数目，可以进一步确定非增补上行载波是否被配置了物理上行控制信道，并在非增补上行载波被配置了物理上行控制信道的情况下，才确定非增补上行载波存在无线链路失败。由于仅被配置了物理上行控制信道的载波，在存在无线链路失败的情况下，才会对用户设备的通信造成较大影响，因此对于未被配置物理上行控制信道的非增补上行载波，即使连续同步的数目小于第三数目，也可以不进行处理(例如不执行步骤S2)，从而减少对用户设备的资源占用。
图6是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图6所示，在图2所示实施例的基础上，若在所述增补上行载波上连续同步的数目小于第二数目，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败还包括：
在步骤S14’中，确定所述增补上行载波是否被配置了物理上行控制信道和物理上行共享信道；
在步骤S15’中，若被配置了物理上行控制信道和物理上行共享信道，确定所述增补上行载波存在无线链路失败；和/或
若在所述非增补上行载波上连续同步的数目小于第四数目，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败还包括：
在步骤S16’中，确定所述非增补上行载波是否被配置了物理上行控制信道和物理上行共享信道；
在步骤S17’中，若被配置了物理上行控制信道和物理上行共享信道，确定所述非增补上行载波存在无线链路失败。
在一个实施例中，基于图2所示的实施例，针对增补上行载波，若连续同步的数目小于第二数目，可以进一步确定增补上行载波是否被配置了物理上行控制信道和物理上行共享信道，并在增补上行载波被配置了物理上行控制信道和物理上行共享信道的情况下，才确定增补上行载波存在无线链路失败。由于仅被配置了物理上行控制信道和物理上行共享信道的载波，在存在无线链路失败的情况下，才会对用户设备的通信造成较大影响，因此对于未被配置物理上行控制信道和物理上行共享信道的增补上行载波，即使连续同步的数目小于第二数目，也可以不进行处理(例如不执行步骤 S2)，从而减少对用户设备的资源占用。
在一个实施例中，基于图2所示的实施例，针对非增补上行载波，若连续同步的数目小于第四数目，可以进一步确定非增补上行载波是否被配置了物理上行控制信道和物理上行共享信道，并在非增补上行载波被配置了物理上行控制信道和物理上行共享信道的情况下，才确定非增补上行载波存在无线链路失败。由于仅被配置了物理上行控制信道和物理上行共享信道的载波，在存在无线链路失败的情况下，才会对用户设备的通信造成较大影响，因此对于未被配置物理上行控制信道和物理上行共享信道的非增补上行载波，即使连续同步的数目小于第三数目，也可以不进行处理(例如不执行步骤S2)，从而减少对用户设备的资源占用。
图7是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图7所示，在图1所示实施例的基础上，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败包括：
在步骤S1A中，在所述增补上行载波上和所述非增补上行载波上发起随机接入；
在步骤S1B中，若在所述增补上行载波上发起的随机接入失败，确定所述增补上行载波存在无线链路失败，和/或若在所述非增补上行载波上发起的随机接入失败，确定所述非增补上行载波存在无线链路失败。
在一个实施例中，除了按照图2所示实施例中，通过监听的方式确定小区的载波是否存在无线链路失败，还可以通过在小区的载波上发起随机接入来确定载波是否存在无线链路失败。
其中，若在增补上行载波上发起的随机接入失败，那么可以确定补上行载波存在无线链路失败，若在非增补上行载波上发起的随机接入失败，可以确定所述非增补上行载波存在无线链路失败。
在一个实施例中，用户设备可以根据基站侧的配置，或者用户设备侧的配置，选择在增补上行载波上发起随机接入，或者在非增补上行载波上发起随机接入，或者在增补上行载波上和非增补上行载波上分别发起随机接入。
图8是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图8所示，在图1所示实施例的基础上，所述确定配置了增补上行载波的小区的增 补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败包括：
在步骤S1C中，确定在所述增补上行载波上和所述非增补上行载波中，被配置了物理上行控制信道的载波；
在步骤S1D中，在所述被配置了物理上行控制信道的载波上发起随机接入；
在步骤S1E中，若在所述被配置了物理上行控制信道的载波上发起的随机接入失败，确定所述增补上行载波存在无线链路失败，和/或所述非增补上行载波存在无线链路失败。
在一个实施例中，可以仅在增补上行载波和非增补上行载波中，被配置了物理上行控制信道的载波上发起随机接入。
由于用户设备在被配置了物理上行控制信道的载波不存在无线链路失败时，即可通过物理上行控制信道传输ACK/NACK，CQI，PMI和RI等信息，从而在一定程度上进行通信。
因此可以仅对被配置了物理上行控制信道发起随机接入，确定被配置了物理上行控制信道的载波是否存在无线链路失败，并在被配置了物理上行控制信道的载波存在无线链路失败的情况下进行处理(例如执行步骤S2)，即可保证在一定程度上进行通信，从而无需在未配置了物理上行控制信道的载波上发起随机接入，减少发起随机接入操作对用户设备的资源占用。
图9是根据本公开一个实施例示出的又一种确定无线链路失败的示意流程图。如图9所示，在图1所示实施例的基础上，所述确定配置了增补上行载波的小区的增补上行载波是否存在无线链路失败，和/或确定非增补上行载波是否存在无线链路失败包括：

在步骤S1G中，在所述被配置了物理上行控制信道和物理上行共享信道的载波上发起随机接入；
在步骤S1H中，若在所述被配置了物理上行控制信道的载波上发起的随机接入失败，确定所述增补上行载波存在无线链路失败，和/或所述非增补上行载波存在无线 链路失败。
在一个实施例中，可以仅在增补上行载波和非增补上行载波中，被配置了物理上行控制信道和物理上行共享信道的载波上发起随机接入。
由于用户设备在被配置了物理上行控制信道和物理上行共享信道的载波不存在无线链路失败时，即可通过物理上行控制信道传输ACK/NACK，CQI，PMI和RI等信息，以及通过物理上行共享信道传输数据，从而正常进行通信。
因此可以仅对被配置了物理上行控制信道和物理上行共享信道发起随机接入，确定被配置了物理上行控制信道和物理上行共享信道的载波是否存在无线链路失败，并在被配置了物理上行控制信道和物理上行共享信道的载波存在无线链路失败的情况下进行处理(例如执行步骤S2)，即可保证正常通信，从而无需在未配置了物理上行控制信道和物理上行共享信道的载波上发起随机接入，减少发起随机接入操作对用户设备的资源占用。
图10是根据本公开一个实施例示出的一种发起连接重建流程和/或向基站传输无线链路失败的信息的示意流程图。如图10所示，在图1所示实施例的基础上，所述发起连接重建流程和/或向基站传输无线链路失败的信息包括：
在步骤S21中，确定所述小区为主小区还是主辅小区；
在步骤S22中，若所述小区为主小区，向所述基站发起连接重建流程；
在步骤S23中，若所述小区为主辅小区，向所述基站传输无线链路失败的信息。
在一个实施例中，在确定配置了增补上行载波的小区存在无线链路失败的情况下，可以进一步区分小区为主小区还是主辅小区，若小区为主小区，可以向基站发起连接重建流程，以使基站恢复主小区的无线链路，保证用户设备能够进行通信；而若小区为主辅小区，由于用户设备仍能通过与主小区之间的无线链路进行通信，因此可以仅向基站传输无线链路失败的信息，而不必发起连接重建流程。
图11是根据本公开另一个实施例示出的一种发起连接重建流程和/或向基站传输无线链路失败的信息的示意流程图。如图11所示，在图1所示实施例的基础上，所述发起连接重建流程和/或向基站传输无线链路失败的信息包括：
在步骤S24中，若所述增补上行载波存在无线链路失败，或所述非增补上行载波存在无线链路失败，确定所述增补上行载波和所述非增补上行载波中，是否存在被 配置了物理上行控制信道的和物理上行共享信道的载波；
在步骤S25中，若存在，确定存在无线链路失败的载波是否是所述被配置了物理上行控制信道的和物理上行共享信道的载波；
在步骤S26中，若不是，向基站传输无线链路失败的信息；
在步骤S27中，若是，在所述小区为主小区的情况下，向所述基站发起连接重建流程，在所述小区为主辅小区的情况下，向所述基站传输无线链路失败的信息。
在一个实施例中，当确定增补上行载波和非增补上行载波中的一个载波存在无线链路失败时，可以确定增补上行载波和非增补上行载波中是否存在被配置了物理上行控制信道的和物理上行共享信道的载波。
若存在被配置了物理上行控制信道的和物理上行共享信道的载波，可以进一步确定存在无线链路失败的载波，是否为被配置了物理上行控制信道的和物理上行共享信道的载波。
若不是被配置了物理上行控制信道的和物理上行共享信道的载波存在无线链路失败，那么用户设备仍然可以通过被配置了物理上行控制信道的和物理上行共享信道的载波进行正常通信，因此无需向基站发起连接重建流程，只需向基站传输无线链路失败的信息即可。
若是被配置了物理上行控制信道的和物理上行共享信道的载波存在无线链路失败，那么用户设备就无法进行正常通信，因此可以向基站发起连接重建流程，以使基站恢复被配置了物理上行控制信道的和物理上行共享信道的载波的无线链路，以便用户设备能够基于被配置了物理上行控制信道的和物理上行共享信道的载波进行正常通信。
图12是根据本公开一个实施例示出的另一种无线链路状态确定方法的示意流程图。如图12所示，在图1所示实施例的基础上，所述无线链路状态确定方法还包括：

在步骤S1’中，根据所述载波选择信息，选择确定所述增补上行载波是否存在无线链路失败，和/或选择确定非增补上行载波是否存在无线链路失败。
在一个实施例中，载波选择信息可以为选择确定增补上行载波是否存在无线链路失败，那么用户设备可以仅确定增补上行载波是否存在无线链路失败。
或者载波选择信息可以为确定非增补上行载波是否存在无线链路，那么用户设备可以仅确定非增补上行载波是否存在无线链路失败。
或者载波选择信息可以为分别确定增补上行载波和非增补上行载波是否存在无线链路失败，那么用户设备可以仅分别确定增补上行载波和非增补上行载波是否存在无线链路失败。
在一个实施例中，载波选择信息可以为在确定增补上行载波存在无线链路失败的情况下，才确定被配置了增补上行载波的小区存在无线链路失败，那么用户设备当确定了增补上行载波存在无线链路失败时，才确定小区存在无线链路失败。
或者载波选择信息可以为在确定非增补上行载波存在无线链路失败的情况下，才确定被配置了增补上行载波的小区存在无线链路失败，那么用户设备当确定了非增补上行载波存在无线链路失败时，才确定小区存在无线链路失败。
或者载波选择信息可以为在确定所述增补上行载波和非增补上行载波都存在无线链路失败的情况下，才确定被配置了增补上行载波的小区存在无线链路失败，那么用户设备当分别确定了增补上行载波和非增补上行载波存在无线链路失败时，才确定所述小区存在无线链路失败。
在一个实施例中，载波选择信息除了可以包含上述两个实施例所示的内容，还可以包含其他情况，例如可以为在确定增补上行载波和非增补上行载波中，被配置了物理上行控制信道的载波和/或物理上行共享信道的载波存在无线链路失败时，才确定被配置了增补上行载波的小区存在无线链路失败。载波信息所包含的内容可以根据需要进行设置，在此不一一赘述。
