Description

确定上行载波的方法和通信装置
本申请要求于2021年5月17日提交中国专利局、申请号为202110534705.1、申请名称为“确定上行载波的方法和通信装置”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
本申请涉及通信领域，尤其涉及一种确定上行载波的方法和通信装置。
背景技术
目前，载波聚合(carrier aggregation，CA)是一项比较关键的技术。在CA中，小区(cell)可以包括主小区(primary cell，Pcell)和辅小区(secondary cell，Scell)。其中，主小区和辅小区均包含一个上行链路分量载波(uplink component carrier，UL CC)和一个下行链路分量载波(downlink component carrier，DL CC)。在灵活接入技术中，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。终端设备可以根据业务需求，在小区内灵活选择上行载波。
目前，一种实现方式下，终端设备可以根据驻留的下行载波接入对应的上行载波。另一种实现方式下，终端设备可以根据驻留的下行载波，在接入时与一个门限值进行比较，若上行载波对应的信号强度低于该门限值，则从增补上行链路(supplementary uplink，SUL)接入；若上行载波对应的信号强度高于该门限值，则从常规上行链路(normal uplink，NUL)接入。
换句话说，当终端设备通过下行载波驻留在某一小区时，可以接入对应的上行载波。然而，当下行载波只有一个用于测量的低频载波作为驻留下行载波，而上行载波处于高频频段，或者上行载波与下行载波分布于不同的站址时，无法直接基于驻留下行载波的测量所得作为上行载波选择的依据。此外，如何从多个上行载波中选择上行接入载波，并考虑所述多个上行载波的负载，从而避免上行载波上的负载失衡，现有技术中也未解决。

还需要说明的是，“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。此外，类似于“A、B和C中的至少一项”或“A、B或C中的至少一项”表述，通常用于表示如下中任一项：至少一个A；至少一个B；至少一个C；至少一个A和至少一个B；至少一个A和至少一个C；至少一个B和至少一个C；至少一个A、至少一个B和至少一个C。以上是以A、B和C共三个元素进行举例来说明该项目的可选用条目，当表述中具有更多元素时，该表述的含义可以按照前述规则获得。
如上所述，本申请的技术方案可以应用于各种通信系统中，其中，应用于上述通信系统中的CA是一项比较关键的技术。在CA中，小区可以包括主小区和辅小区。其中，主小区和辅小区均包含一个上行链路分量载波和一个下行链路分量载波。在灵活接入技术中，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。UE可以根据业务需求，在小区内灵活选择上行载波。
目前，一种实现方式下，终端设备可以根据驻留的下行载波接入对应的上行载波。另一种实现方式下，UE可以根据驻留的下行载波，在接入时与一个门限值进行比较，若上行载波对应的信号强度低于该门限值，则从SUL接入；若下行载波对应的信号强度高于该门限值，则从NUL接入。
换句话说，当终端设备通过下行载波驻留在某一小区时，可以接入对应的上行载波。然而，当下行载波只有一个用于测量的低频载波作为驻留下行载波，而上行载波处于高频频段，或者上行载波与下行载波分布于不同的站址时，无法直接基于驻留下行载波的测量所得作为上行载波选择的依据。此外，如何从多个上行载波中选择上行接入载波，并考虑所述多个上行载波的负载，从而避免上行载波上的负载失衡，现有技术中也未解决。
本申请提供一种确定上行载波的方法，可以使得终端设备接入到匹配的上行载波上，均衡负载。
如图2所示，为本申请实施例提供的一种确定上行载波的方法200的示意图，该方法200可以由终端设备和网络设备执行，或者也可以由终端设备中的芯片和网络设备中的芯片执行。该方法200可以包括步骤S210-S240。本申请实施例中示出的单个执行主体(例如，网络设备、终端设备)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。
S210，网络设备确定至少一个第一上行载波的第一参数，该第一参数与该至少一个第一上行载波的下述项中的至少一项相关联：负载、SCS。
S220，该网络设备向终端设备发送该至少一个第一上行载波的第一参数。
其中，该步骤S210-S220可以由图1中的网络设备10执行。
S230，从网络设备接收至少一个第一上行载波的第一参数。
S240，根据该至少一个第一上行载波的第一参数，从该至少一个第一上行载波确定第二上行载波，该第二上行载波为用于接入的上行载波。
其中，该步骤230-240可以由图1中的终端设备20-终端设备40中的任意终端设备执行。
本申请实施例中，该至少一个第一上行载波可以包括1个或多个上行载波，若该至少一个第一上行载波包括1个上行载波，则第二上行载波即为该1个上行载波；若该至少一个第一上行载波包括多个上行载波，则第二上行载波为这多个上行载波的其中1个上行载波。本申请中的载波仅仅是示例，还可以是部分带宽、频带、或波束，可以理解为将本申请实施例中的“载波”替换为“部分带宽”、“频段”或“波束”后依然适用于本申请中的技术方案。
需要说明的是，本申请实施例中，该第二上行载波为用于接入的上行载波，可以理解为：终端设备在该第二上行载波上进行随机接入。
还需要说明的是，在一些实施例中，第一参数也可以为称为状态值，不予限制。
本申请提供的方案，终端设备可以根据接收到的至少一个第一上行载波的第一参数，从该至少一个第一上行载波中确定第二上行载波。由于终端设备在确定用于接入的第二上行载波时，是基于至少一个第一上行载波的第一参数确定的，可以使终端设备接入到匹配的上行载波，均衡负载，从而提升系统性能。
上文指出，终端设备可以根据该至少一个第一上行载波的第一参数，从该至少一个第一上行载波确定第二上行载波，下文将介绍终端设备确定第二上行载波的可能的几种方式。
方式一：
该第二上行载波为该至少一个第一上行载波中第一参数最大的上行载波；或者，该第二上行载波为该至少一个第一上行载波中第一参数最小的上行载波。
本申请实施例中，第二上行载波可以为至少一个第一上行载波中第一参数最大的上行载波，也可以为至少一个第一上行载波中第一参数最小的上行载波，主要与第一参数和其所关联的负载和/或SCS有关。
可选地，在一些实施例中，下述项中的至少一项越大，该第一参数越小：该负载、该SCS；或者，下述项中的至少一项越大，该第一参数越大：该负载、该SCS。
换句话说，第一参数可以与负载和/或SCS负相关(即负载和/或SCS越大，第一参数越小)，也可以与负载和/或SCS正相关(即负载和/或SCS越大，第一参数越大)。
若第一参数与负载和/或SCS负相关，则第二上行载波可以为至少一个第一上行载波中第一参数最大的上行载波；若第一参数与负载和/或SCS正相关，则第二上行载波可以为至少一个第一上行载波中第一参数最小的上行载波。
下文将分情况介绍确定第二上行载波的具体实现过程。
情况一：第二上行载波为至少一个第一上行载波中第一参数最大的上行载波
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，终端设备可以根据每一个上行载波的第一参数确定用于接入的第二上行载波。
该第一参数可以基于上行载波所关联的负载或SCS确定。即：上行载波所关联的负载越大，其第一参数越小；上行载波所关联的负载越小，其第一参数越大。类似地，上行载波的SCS越大，其第一参数越小；上行载波的SCS越小，其第一参数越大。
以负载为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的负载依次为5、4、7、2、4，在一种实现方式中，由于这5个上行载波中上行载波4的负载最小，相应地，上行载波4的第一参数最大，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波4>上行载波5＝上行载波2>上行载波1>上行载波3。由于上行载波4的第一参数最大，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
以SCS为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上 行载波4和上行载波5)所关联的SCS依次为50KHz、40KHz、70KHz、20KHz、40KHz，在一种实现方式中，由于这5个上行载波中上行载波4的SCS最小，相应地，上行载波4的第一参数最大，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波4>上行载5＝上行载波2>上行载波1>上行载波3。由于上行载波4的第一参数最大，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
情况二：第二上行载波为至少一个第一上行载波中第一参数最小的上行载波
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，终端设备可以根据每一个上行载波的第一参数确定用于接入的第二上行载波。
该第一参数可以基于上行载波所关联的负载或SCS确定。即：上行载波所关联的负载越大，其第一参数越大；上行载波所关联的负载越小，其第一参数越小。类似地，上行载波的SCS越大，其第一参数越大；上行载波的SCS越小，其第一参数越小。
以负载为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的负载依次为5、4、7、2、4，在一种实现方式中，由于这5个上行载波中上行载波4的负载最小，相应地，上行载波4的第一参数最小，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4。由于上行载波4的第一参数最小，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
以SCS为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的SCS依次为50KHz、40KHz、70KHz、20KHz、40KHz，在一种实现方式中，由于这5个上行载波中上行载波4的SCS最小，相应地，上行载波4的第一参数最小，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的SCS的大小进行排序，排列后的顺序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波3>上行载波1>上行载波2＝上行载波5>上行载波4。由于上行载波4的第一参数最小，此时终端设备可以选择上行载波4作为用于接入的第二上行载波。
本申请提供的方案，终端设备确定的第二上行载波可以为至少一个第一上行载波中第一参数最大或最小的上行载波，由于第一参数与至少一个第一上行载波的下述项中的至少一项相关联：负载、SCS，从而终端设备基于该第一参数接入到匹配的上行载波，减少接入时延，均衡负载，从而提升系统性能。
方式二：
该方法200还可以包括：确定第一数值；其中，该第二上行载波为至少一个第三上行 载波中序号最大的上行载波；或者，该第二上行载波为至少一个第三上行载波中序号最小的上行载波；其中，该至少一个第三上行载波为该至少一个第一上行载波中第一参数大于该第一数值的上行载波；或者，该至少一个第三上行载波为该至少一个第一上行载波中第一参数小于该第一数值的上行载波。
本申请实施例中，第二上行载波可以为至少一个第三上行载波中序号最大的上行载波，也可以为至少一个第三上行载波中序号最小的上行载波；本申请实施例中的至少一个第三上行载波可以为至少一个第一上行载波中第一参数大于第一数值的上行载波，也可以为至少一个第一上行载波中第一参数小于第一数值的上行载波；不予限制。
应理解，在一些实施例中，本申请实施例中的至少一个第三上行载波可以为至少一个第一上行载波中第一参数大于或等于(或者称为不小于)第一数值的上行载波，也可以为至少一个第一上行载波中第一参数小于或等于(或者称为不大于)第一数值的上行载波；不予限制。
本申请实施例中，至少一个第三上行载波可以为至少一个第一上行载波中第一参数大于第一数值的上行载波，也可以为至少一个第一上行载波中第一参数小于第一数值的上行载波，主要与第一参数和其所关联的负载和/或SCS有关。
可选地，在一些实施例中，下述项中的至少一项越大，该第一参数越小：该负载、该SCS；或者，下述项中的至少一项越大，该第一参数越大：该负载、该SCS。
换句话说，第一参数可以与负载和/或SCS负相关(即负载和/或SCS越大，第一参数越小)，也可以与负载和/或SCS正相关(即负载和/或SCS越大，第一参数越大)。
若第一参数与负载和/或SCS负相关，则至少一个第三上行载波可以为至少一个第一上行载波中第一参数大于第一数值的上行载波；若第一参数与负载和/或SCS正相关，则至少一个第三上行载波可以为至少一个第一上行载波中第一参数小于第一数值的上行载波。
下文将分情况介绍确定第二上行载波的具体实现过程。
情况一：至少一个第三上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波
(1)第二上行载波为至少一个第三上行载波中序号最大的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将至少一个第一上行载波按照序号进行降序排列，即，按照序号从大到小的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照序号从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波中序号最大的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1(序号为“0”)、上行载波2(序号为“1”)、上行载波3(序号为“2”)、上行载波4(序号为“3”)和上行载波5(序号为“4”)，其负载依次为5、4、7、2、4，则第一参数可以依次为0.5、0.8、0.3、0.9、0.8，若第一数值为0.6，则终端设备可以先将序号最大的上行载波5的第一参数0.8与第一数值进行比较，由于0.8>0.6，因此，终端设备可以选择上行载波5作为用于接入的第二上行载波。
(2)第二上行载波为至少一个第三上行载波中序号最小的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将至少一个第一上行载波按照序号进行升序排列，即，按照序号从小到大的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照序号从小到大的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波中序号最小的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1(序号为“0”)、上行载波2(序号为“1”)、上行载波3(序号为“2”)、上行载波4(序号为“3”)和上行载波5(序号为“4”)，其负载依次为5、4、7、2、4，则第一参数可以依次为0.5、0.8、0.3、0.9、0.8，若第一数值为0.6，则终端设备可以先将序号最小上行载波1的第一参数0.5与数值进行比较，由于0.5<0.6，因此，终端设备可以将序号次小的上行载波2的第一参数0.8与该数值进行比较，由于0.8>0.6，因此，终端设备可以选择上行载波2作为用于接入的第二上行载波。
情况二：至少一个第三上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波
(1)第二上行载波为至少一个第三上行载波中序号最大的上行载波

在另一种实现方式中，终端设备可以将至少一个第一上行载波按照序号进行降序排列，即，按照序号从大到小的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数小于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照序号从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使 得确定出的第二上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波中序号最大的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1(序号为“0”)、上行载波2(序号为“1”)、上行载波3(序号为“2”)、上行载波4(序号为“3”)和上行载波5(序号为“4”)，其负载依次为5、4、7、2、4，则第一参数可以依次为0.5、0.8、0.3、0.9、0.8，若第一数值为0.6，则终端设备可以先将序号最大的上行载波5的第一参数0.8与第一数值进行比较，由于0.8>0.6，终端设备继续将序号次大的上行载波4的第一参数0.9与第一数值进行比较，同样地，由于0.9>0.6，终端设备继续将序号次大的上行载波3的第一参数0.3与第一数值进行比较，由于0.3<0.6，因此，终端设备可以选择上行载波3作为用于接入的第二上行载波。

在另一种实现方式中，终端设备可以将至少一个第一上行载波按照序号进行升序排列，即，按照序号从小到大的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数小于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照序号从小到大的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波中序号最小的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1(序号为“0”)、上行载波2(序号为“1”)、上行载波3(序号为“2”)、上行载波4(序号为“3”)和上行载波5(序号为“4”)，其负载依次为5、4、7、2、4，则第一参数可以依次为0.5、0.8、0.3、0.9、0.8，若第一数值为0.6，则终端设备可以先将序号最小的上行载波1的第一参数0.5与第一数值进行比较，由于0.5＝0.5，因此，终端设备可以将序号次小的上行载波2的第一参数0.8与该第一数值进行比较，由于0.8>0.6，因此，终端设备可以继续将序号次小的上行载波3的第一参数0.3与该第一数值进行比较，由于0.3<0.6因此，终端设备可以选择上行载波3作为用于接入的第二上行载波。
本申请提供的方案，终端设备确定的第二上行载波可以为至少一个第三上行载波中序号最大或最小的上行载波，且该第三上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波，或者，该第三上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波。由于终端设备从筛选后的至少一个第三上行载波中确定用于接入的第二上行载波，相当于缩小了选择范围，进一步地，可以减少接入时延，从而提升系统性能。
方式三：
该方法200还可以包括：确定第一数值；其中，该第二上行载波为至少一个第三上行载波中信号强度最高的上行载波；或者，该第二上行载波为至少一个第三上行载波中，与该至少一个第三上行载波相关联的下行载波的信号强度最高的上行载波；其中，该至少一个第三上行载波为该至少一个第一上行载波中第一参数大于该第一数值的上行载波；或者，该至少一个第三上行载波为该至少一个第一上行载波中第一参数小于该第一数值的上行载波。

应理解，在一些实施例中，本申请实施例中的至少一个第三上行载波可以为至少一个第一上行载波中第一参数大于或等于(或者称为不小于)第一数值的上行载波，也可以为至少一个第一上行载波中第一参数小于或等于(或者称为不大于)第一数值的上行载波；不予限制。
下文将分情况介绍确定第二上行载波的具体实现过程。
情况一：至少一个第三上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波
(1)第二上行载波为至少一个第三上行载波中信号强度最高的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将至少一个第一上行载波按照信号强度进行降序排列，即，按照信号强度从大到小的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照信号强度从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波中信号强度最大的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行 载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，其信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm，第一参数依次分别为0.5、0.4、0.7、0.2、0.4，若第一数值为0.5，终端设备可以先将信号强度最大的上行载波3的第一参数0.7与第一数值进行比较，由于0.7>0.5，因此，终端设备可以选择上行载波3作为用于接入的第二上行载波。
(2)该第二上行载波为至少一个第三上行载波中，与该至少一个第三上行载波相关联的下行载波的信号强度最高的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将与至少一个第一上行载波相关联的下行载波按照信号强度进行降序排列，即，按照信号强度从大到小的顺序对与至少一个第一上行载波相关联的下行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照信号强度从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数大于第一数值的与上行载波相关联的下行载波中信号强度最大的所对应的上行载波，其他的实现方式同样适用于本实施例。
示例性地，如图3所示，为本申请实施例提供的一种载波位置的示意图。参考图3，假设终端设备驻留在某一小区(即图3中的小区1)的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，第一参数依次分别为0.5、0.4、0.7、0.2、0.4，且这5个上行载波在其它小区(如图3中所示的小区2、小区3、小区4、小区5、小区6)所关联的下行载波分别为下行载波1’、下行载波2’、下行载波3’、下行载波4’和下行载波5’，其信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm，若第一数值为0.5，终端设备可以先将信号强度最大的下行载波所对应的上行载波3的第一参数0.7与第一数值进行比较，由于0.7>0.5，因此，终端设备可以选择上行载波3作为用于接入的第二上行载波。
情况二：至少一个第三上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波
(1)第二上行载波为至少一个第三上行载波中信号强度最高的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将至少一个第一上行载波按照信号强度进行降序排列，即，按照信号强度从大到小的顺序对至少一个第一上行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数小于该数值，则终端设备可以选择该上行载波为第二上 行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照信号强度从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波中信号强度最大的上行载波，其他的实现方式同样适用于本实施例。
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，其信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm，第一参数依次分别为0.5、0.4、0.7、0.2、0.4，若第一数值为0.5，终端设备可以先将信号强度最大的上行载波3的第一参数0.7与第一数值进行比较，由于0.7>0.5，因此，终端设备可以将信号强度次大的上行载波2的第一参数0.4与第一数值进行比较，由于0.4<0.5，因此，终端设备可以选择上行载波2作为用于接入的第二上行载波。
(2)该第二上行载波为至少一个第三上行载波中，与该至少一个第三上行载波相关联的下行载波的信号强度最高的上行载波
在一种实现方式中，终端设备可以先确定符合条件的至少一个第三上行载波，再从这至少一个第三上行载波中选择用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将与至少一个第一上行载波相关联的下行载波按照信号强度进行降序排列，即，按照信号强度从大到小的顺序对与至少一个第一上行载波相关联的下行载波进行排列。然后，终端设备可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与第一数值进行比较，若某一上行载波的第一参数小于该数值，则终端设备可以选择该上行载波为第二上行载波，也就是说，排列后的至少一个第一上行载波中第一个符合条件的上行载波为第二上行载波。在这种实现方式中，也可以不对至少一个第一上行载波进行排列，直接按照信号强度从大到小的顺序将第一上行载波的第一参数与第一数值进行比较。
应理解的是，终端设备确定第二上行载波的方式并不限于上述实现方式，只要能够使得确定出的第二上行载波为至少一个第一上行载波中第一参数小于第一数值的与上行载波相关联的下行载波中信号强度最大的所对应的上行载波，其他的实现方式同样适用于本实施例。
示例性地，参考上述图3，假设终端设备驻留在某一小区(即图3中的小区1)的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，第一参数依次分别为0.5、0.4、0.7、0.2、0.4，且这5个上行载波在其它小区(如图3中所示的小区2、小区3、小区4、小区5、小区6)所关联的下行载波分别为下行载波1’、下行载波2’、下行载波3’、下行载波4’和下行载波5’，其信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm，若第一数值为0.5，终端设备可以先将信号强度最大的下行载波3’所关联的上行载波3的第一参数0.7与第一数值进行比较，由于0.7>0.5，因此，终端设备可以将信号强度次大下行载波2’所关联的上行载波2的第一参数0.4与第一数值进行比较，由于0.4<0.5，因此，终端设备可以选择上行载波3作为用于接入的第二上行载波。
本申请提供的方案，终端设备确定的第二上行载波可以为至少一个第三上行载波中信号强度最高的上行载波，或者，第二上行载波可以为至少一个第三上行载波中，与至少一个第三上行载波相关联的下行载波的信号强度最高的上行载波；且该第三上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波；或者，该第三上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波。由于终端设备从筛选后的至少一个第三上行载波中确定用于接入的第二上行载波，相当于缩小了选择范围，进一步地，可以减少接入时延，从而提升系统性能。
在上述方式三中，终端设备可以基于第一数值确定至少一个第三上行载波，并从至少一个第三上行载波中确定用于接入的第二上行载波。其中，该第一数值可以基于以下方式确定。
可选地，在一些实施例中，该第一数值大于或等于0且小于或等于第三阈值。该第三阈值关联于下述项中的至少一项：服务质量(quality of service，QoS)级别、缓冲状态报告(buffer status report，BSR)级别、终端设备的类型、时延要求、终端设备的业务类型。
本申请实施例中的第三阈值基于上述至少一项的不同而不同，第一数值可以为0至第三阈值的任一数值。
本申请以关联终端设备的类型为例，终端设备可以为支持超高可靠超低时延通信(ultra-relaible and low latency communication，URLLC)的终端设备、支持增强移动宽带(enhanced mobile broadband，eMBB)的终端设备、支持大规模机器类型通信(massive machine type communication，mMTC)的终端设备中的任意终端设备。
示例性地，若终端设备为支持URLLC的终端设备，第三阈值可以为1；若终端设备为支持eMBB的终端设备，第三阈值可以为2；若终端设备为支持mMTC的终端设备，第三阈值可以为3。换句话说，支持URLLC的终端设备情况下的第三阈值<支持eMBB的终端设备情况下的第三阈值<支持mMTC的终端设备情况下的第三阈值。
需要说明的是，在第三阈值取值不同时，第一数值可以相同，也可以不同，不予限制。
示例性地，若第三阈值为1，第一数值可以为0.5，若第三阈值为2，第一数值可以为0.5，也可以为0.6；当然，在第三阈值为1的情况下，第一数值可以为0.5，也可以为0.6；不予限制。
可以理解的是，在第一数值取值不同的情况下，上述方式三中至少一个第三上行载波的数量可能不同。
在方式三中，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)的第一参数分别为0.5、0.4、0.7、0.2、0.4，且第一数值为0.5。由于上行载波1和上行载波3的第一参数大于第一数值0.5，则本申请实施例中的第三上行载波可以包括上行载波1和上行载波3，此时终端设备可以从这2个上行载波中根据这2个上行载波的信号强度确定用于接入的第二上行载波。
若第一数值为0.6，此时由于上行载波3的第一参数大于第一数值0.6，则本申请实施例中的第三上行载波可以包括上行载波3，此时终端设备可以选择上行载波3为用于接入的第二上行载波。
当然，在一些实施例中，若至少一个第三上行载波为至少一个第一上行载波中第一参数大于第一数值的上行载波，有可能第一数值过大，至少一个第一上行载波中没有上行载 波的第一参数大于第一数值，即：没有满足条件的至少一个第三上行载波。此时，可以将第三阈值进行缩放，并根据缩放后的第三阈值确定第一数值，以及确定至少一个第三上行载波。
示例性地，仍然假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)的第一参数分别为0.5、0.4、0.7、0.2、0.4，第三阈值为1，且第一数值为0.8。由于这5个上行载波中没有上行载波的第一参数大于第一数值0.8，此时，可以将第三阈值进行缩放，如将该第三阈值缩放为0.5，第一数值可以为0.4，由于上行载波1、上行载波2、上行载波3和上行载波5的第一参数大于第一数值0.4，则本申请实施例中的第三上行载波可以包括上行载波1、上行载波2、上行载波3和上行载波5，此时终端设备可以从这4上行载波中根据这4个上行载波的信号强度确定用于接入的第二上行载波。
对于至少一个第三上行载波为至少一个第一上行载波中第一参数小于第一数值的上行载波，与上述情况类似，为了简洁，这里不再赘述。
此外，在一些实施例中，终端设备确定第一数值时，也可以在一个范围内随机生成。可选地，该范围可以根据以第三阈值为参数的一个函数生成。还可以根据自身标识信息生成的。可选地，根据自身标识信息生成可以根据以自身标识信息为参数的一个函数生成。该函数可以为线性函数或者非线性函数。作为示例，当标识信息用标识(identity，ID)表示时，该函数可以为ID mod N，其中N为函数中的参数。可选地，N可以为正整数。其中，ID mod N标识ID除以N后的余数。如，ID为10，N为3，则ID mod N＝10 mod 3＝1。
作为示例，当标识信息用国际移动用户识别码(international mobile subscriber identification，IMSI)表示时，该函数可以为IMSI mod N，其中N为函数中的参数。可选地，N可以为正整数。
可选地，在一些实施例中，该第三阈值为网络设备通过无线资源控制(radio resource control，RRC)信令配置的；或者，该第三阈值为预定义的。
本申请提供的方案，第一数值可以为0至第三阈值中的任一数值，而该第三阈值关联于下述项中的至少一项：QoS级别、BSR级别、终端设备的类型、时延要求、终端设备的业务类型。即：第三阈值随着上述项中的至少一项的不同而可能不同，进而第一数值可以随着第三阈值的不同而改变，可以调整符合条件的至少一个第三上行载波，从而可以提升终端设备选择第二上行载波的灵活性。
本申请实施例中，当该第三阈值为网络设备通过无线资源控制RRC信令配置的时，网络设备通过无线资源控制RRC信令配置多个可选的第三阈值。该多个可选的第三阈值对应不同的业务类型或级别。具体来说，该第三阈值关联于下述项中的至少一项：QoS级别、BSR级别、终端设备的类型、时延要求、终端设备的业务类型。
在一些实施例中，终端设备也可以根据自身的下述选项中至少一项选择确定第三阈值，其中下述选项包括：QoS级别、BSR级别、终端设备的类型、时延要求、终端设备的业务类型。
上文介绍了确定第二上行载波的三种方式，从本质上来说，这三种方式中，均是从至少一个第一上行载波中确定该第二上行载波的，关于至少一个第一上行载波的描述请参见下文。
该至少一个第一上行载波为该网络设备配置的至少一个上行载波中信号强度大于或等于第一阈值的上行载波；或者，
该至少一个第一上行载波为该网络设备配置的至少一个上行载波中，与该至少一个上行载波相关联的下行载波的信号强度大于或等于第二阈值的上行载波。
下文将分情况介绍至少一个第一上行载波的内容。
情况一：至少一个第一上行载波为该网络设备配置的至少一个上行载波中信号强度大于或等于第一阈值的上行载波。
示例性地，假设系统中包括10个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4、上行载波5、上行载波6、上行载波7、上行载波8、上行载波9和上行载波10，这10个上行载波的信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm、-180dBm、-170dBm、-160dBm、-190dBm、-200dBm，若第一阈值为-120dBm，则本申请中的至少一个第一上行载波可以包括上行载波1、上行载波2、上行载波3、上行载波4、上行载波5。换句话说，网络设备可以将这5个上行载波配置于小区。
情况二：至少一个第一上行载波为该网络设备配置的至少一个上行载波中，与该至少一个上行载波相关联的下行载波的信号强度大于或等于第二阈值的上行载波。
示例性地，假设系统中包括10个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4、上行载波5、上行载波6、上行载波7、上行载波8、上行载波9和上行载波10，与这10个上行载波相关联的下行载波的信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm、-180dBm、-170dBm、-160dBm、-190dBm、-200dBm，若第一阈值为-120dBm，则本申请中的至少一个第一上行载波可以包括上行载波1、上行载波2、上行载波3、上行载波4、上行载波5。换句话说，网络设备可以将这5个上行载波配置于小区。
本申请提供的方案，至少一个第一上行载波为网络设备配置的至少一个上行载波中信号强度大于或等于第一阈值的上行载波，或者，为网络设备配置的至少一个上行载波中，与至少一个上行载波相关联的下行载波的信号强度大于或等于第二阈值的上行载波。由于该至少一个第一上行载波是网络设备从多个上行载波中选择的，为终端设备确定第二上行载波缩小了选择范围，进一步地，可以减少接入时延，从而提升系统性能。
可选地，在一些实施例中，下述项中的至少一项越大，该第一参数越小：该负载、该SCS；或者，下述项中的至少一项越大，该第一参数越大：该负载、该SCS。
换句话说，第一参数可以与负载和/或SCS负相关(即负载和/或SCS越大，第一参数越小)，也可以与负载和/或SCS正相关(即负载和/或SCS越大，第一参数越大)。
若第一参数与负载和/或SCS负相关，则第二上行载波可以为至少一个第一上行载波中第一参数最大的上行载波；若第一参数与负载和/或SCS正相关，则第二上行载波可以为至少一个第一上行载波中第一参数最小的上行载波，下文将分别举例说明。
(1)负载和/或SCS越大，第一参数越小
示例性地，假设终端设备驻留在某一小区的下行载波上，该下行载波对应有多个上行载波，如5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，此时终端设备可以根据这5个上行载波所关联的负载或SCS确定其第一参数，并根据该第一参数确定用于接入的第二上行载波(假设以上述方式一为例)。
该第一参数可以基于上行载波所关联的负载或SCS确定。即：上行载波所关联的负载越大，其第一参数越小；上行载波所关联的负载越小，其第一参数越大。类似地，上行载波的SCS越大，其第一参数越小；上行载波的SCS越小，其第一参数越大。
以负载为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的负载依次为5、4、7、6、4，在一种实现方式中，由于这4个上行载波中上行载波2和上行载波5的负载最小且均为4，相应地，上行载波2和上行载波5的第一参数并列最大，若基于上述方式一，此时终端设备可以选择上行载波2或上行载波5作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波5＝上行载波2>上行载波1>上行载波4>上行载波3。由于上行载波5和上行载波2的第一参数并列最大，若基于上述方式一，此时终端设备可以选择上行载波5或上行载波2作为用于接入的第二上行载波。
以SCS为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的SCS依次为50KHz、40KHz、70KHz、60KHz、40KHz，在一种实现方式中，由于这5个上行载波中上行载波5和上行载波2的SCS并列最小，相应地，上行载波5和上行载波2的第一参数并列最大，若基于上述方式一，此时终端设备可以选择上行载波5或上行载波2作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波5＝上行载波2>上行载波1>上行载波4>上行载波3。由于上行载波5和上行载波2的第一参数并列最大，若基于上述方式一，此时终端设备可以选择上行载波5或上行载波2作为用于接入的第二上行载波。
在一些实施例中，终端设备也可以不为至少一个第一上行载波中第一参数最大或最小的上行载波，终端设备也可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与某一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波。如，上述5个上行载波所关联的负载依次为5、4、7、6、4，则第一参数可以依次为0.5、0.8、0.3、0.4、0.8，若数值为0.6，则终端设备可以先将上行载波1的第一参数0.5与数值进行比较，由于0.5<0.6，因此，终端设备可以选择上行载波2的第一参数0.8与该数值进行比较，由于0.8>0.6，则终端设备可以选择上行载波2作为用于接入的第二上行载波。
(2)负载和/或SCS越大，第一参数越大
同样地，终端设备可以根据上述5个上行载波所关联的负载或SCS确定其第一参数，并根据该第一参数确定用于接入的第二上行载波(假设仍然以上述方式一为例)。
该第一参数可以基于上行载波所关联的负载或SCS确定。即：上行载波所关联的负载越大，其第一参数越大；上行载波所关联的负载越小，其第一参数越小。类似地，上行载波的SCS越大，其第一参数越大；上行载波的SCS越小，其第一参数越小。
以负载为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的负载依次为5、4、7、6、4，在一种实现方式中，由于 这5个上行载波中上行载波2和上行载波5的负载最小，相应地，上行载波2和上行载波5的第一参数最小，此时终端设备可以选择上行载波2或上行载波5作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的负载的大小进行排序，排列后的顺序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5，按照该排序，则这5个上行载波按照第一参数的排序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5。由于上行载波2和上行载波5的第一参数最小，此时终端设备可以选择上行载波2或上行载波5作为用于接入的第二上行载波。
以SCS为例，假设上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)所关联的SCS依次为50KHz、40KHz、70KHz、60KHz、40KHz，在一种实现方式中，由于这5个上行载波中上行载波2和上行载波5的SCS最小，相应地，上行载波2和上行载波5的第一参数最小，此时终端设备可以选择上行载波2或上行载波5作为用于接入的第二上行载波。
在另一种实现方式中，终端设备可以将这5个上行载波按照所关联的SCS的大小进行排序，排列后的顺序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5，按照该排序，则这4个上行载波按照第一参数的排序为：上行载波3>上行载波4>上行载波1>上行载波2＝上行载波5。由于上行载波2和上行载波5的第一参数最小，此时终端设备可以选择上行载波2或上行载波5作为用于接入的第二上行载波。
在一些实施例中，终端设备也可以不为至少一个第一上行载波中第一参数最大或最小的上行载波，终端设备也可以将至少一个第一上行载波中的每一个上行载波的第一参数依次与某一数值进行比较，若某一上行载波的第一参数大于该数值，则终端设备可以选择该上行载波为第二上行载波。如，上述5个上行载波(即上行载波1、上行载波2、上行载波3、上行载波4和上行载波5)依次为5、4、7、6、4，则第一参数可以依次为0.5、0.4、0.7、0.6、0.4，若数值为0.6，则终端设备可以先将上行载波1的第一参数0.5与数值进行比较，由于0.5<0.6，因此，终端设备可以将上行载波2的第一参数0.4与该数值进行比较，由于0.4<0.6，则终端设备可以继续将上行载波3的第一参数0.7与该数值进行比较，由于0.7>0.6，因此，终端设备可以将上行载波3作为用于接入的第二上行载波。
需要说明的是，本申请实施例中的第一阈值和/或第二阈值可以为预配置的，也可以是网络设备通过信令配置的，也可以为协议规定的，还可以是终端设备根据自身的性能确定的。该第一阈值和/或第二阈值可以为固定值，也可以为动态值；不予限制。终端设备根据自身的性能确定，可以是在网络设备配置的阈值中根据自身的特性确定的。
应理解，上述各实施例中所示出的数值仅为举例说明，还可以为其它数值，不应对本申请造成特别限定。
如图4所示，为本申请实施例提供的另一种确定上行载波的方法400的示意图，该方法400可以由终端设备和网络设备执行，或者也可以由终端设备中的芯片和网络设备中的芯片执行。该方法400可以包括步骤S410-S440。
S410，网络设备确定第一信息，该第一信息包含至少一个第一上行载波与至少一个第二下行载波的对应信息。
S420，该网络设备向终端设备发送该第一信息。
其中，该步骤S410-S420可以由图1中的网络设备10执行。
S430，终端设备接收第一信息。
S440，该终端设备根据第一信息从该至少一个第一上行载波中确定第二上行载波，该第二上行载波为第一小区中用于接入的上行载波。
其中，该至少一个第一上行载波与第二下行载波位于第二小区，且该至少一个第一上行载波位于该第一小区；或者，该至少一个第一上行载波与第一下行载波位于该第一小区。
其中，该步骤430-440可以由图1中的终端设备20-终端设备40中的任意终端设备执行。
本申请实施例中，该至少一个第一上行载波可以包括1个或多个上行载波，若该至少一个第一上行载波包括1个上行载波，则第二上行载波即为该1个上行载波；若该至少一个第一上行载波包括多个上行载波，则第二上行载波为这多个上行载波的其中1个上行载波。
需要说明的是，本申请实施例中，该第二上行载波为用于接入的上行载波，可以理解为：终端设备在该第二上行载波上进行随机接入。
本申请提供的方案，终端设备可以根据接收到的至少一个第一上行载波与至少一个第二下行载波的对应信息从该至少一个第一上行载波中确定第二上行载波。由于终端设备在确定用于接入的第二上行载波时，是基于至少一个第一上行载波与至少一个第二下行载波的对应信息确定的，可以使终端设备接入到匹配的上行载波，保证覆盖性能，从而提升系统吞吐量。
上文指出，终端设备根据第一信息从该至少一个第一上行载波中确定第二上行载波，下文将介绍终端设备确定第二上行载波的可能的几种方式。
方式一：
该方法400还包括：该终端设备确定该至少一个第二下行载波的信号强度；该第二上行载波为该至少一个第二下行载波中的信号强度最高的所对应的上行载波。
本申请实施例中，终端设备在接收到第一信息确定至少一个第一上行载波与至少一个第二下行载波的对应信息后，可以先确定该至少一个第二下行载波的信号强度，并从至少一个第二下行载波中确定其中信号强度最高的下行载波所对应的上行载波为用于接入的第二上行载波。
仍然参考上述图3，假设本申请的至少一个第一上行载波包括5个上行载波，分别为上行载波1、上行载波2、上行载波3、上行载波4和上行载波5，至少一个第二下行载波包括5个下行载波，分别为下行载波1’、下行载波2’、下行载波3’、下行载波4’和下行载波5’，此时，终端设备可以先确定这5个下行载波的信号强度，如这5个下行载波的信号强度依次分别为-80dBm、-70dBm、-60dBm、-110dBm、-100dBm，由于下行载波3’的信号强度最高，因此，终端设备可以选择下行载波3’所对应的上行载波3为用于接入的第二上行载波。
本申请提供的方案，终端设备确定的第二上行载波可以为至少一个第二下行载波中的信号强度最高的所对应的上行载波，由于信号强度越高，覆盖程度越好，从而终端设备基于该信号强度接入到匹配的上行载波，增大接入概率，减少接入时延，从而提升系统性能。
方式二：
该方法400还包括：该终端设备接收该至少一个第一上行载波的第一参数，该第一参数与该至少一个第一上行载波的下述项中的至少一项相关联：负载、子载波间隔SCS；确定第一数值；该第二上行载波为至少一个第三上行载波中序号最大的上行载波；或者，该第二上行载波为该至少一个第三上行载波中序号最小的上行载波；其中，该至少一个第三上行载波为该至少一个第一上行载波中第一参数大于第一数值的上行载波；或者，该至少一个第三上行载波为该至少一个第一上行载波中第一参数小于该第一数值的上行载波。
本申请方式二的具体实施方式可以参考上述方法200中的方式二中的相关内容，在此不再赘述。
方式三：
该终端设备接收该至少一个第一上行载波的第一参数，该第一参数与该至少一个第一上行载波的下述项中的至少一项相关联：负载、SCS；确定第一数值；其中，该第二上行载波为至少一个第三上行载波中，与该至少一个第三上行载波相关联的该至少一个第二下行载波的信号强度最高的上行载波；或者，其中，该至少一个第三上行载波为该至少一个第一上行载波中第一参数大于该第一数值的上行载波；或者，该至少一个第三上行载波为该至少一个第一上行载波中第一参数小于该第一数值的上行载波。
本申请方式三的具体实施方式可以参考上述方法200中的方式三中的相关内容，在此不再赘述。
可选地，在一些实施例中，该第一数值大于或等于0且小于或等于第三阈值，该第三阈值关联于下述项中的至少一项：QoS级别、BSR级别、终端设备的类型、时延要求、终端设备的业务类型。
可选地，在一些实施例中，该第三阈值为网络设备通过RRC信令配置的；或者，该第三阈值为预定义的。
可选地，在一些实施例中，下述项中的至少一项越大，该第一参数越小：该负载、该SCS；或者，下述项中的至少一项越大，该第一参数越大：该负载、该SCS。
上述实施例均可参考方法200中的相关内容，在此不再赘述。
如图5所示，为本申请实施例提供的一种测量方法500的示意图，该方法500可以由终端设备执行，或者也可以由终端设备中的芯片执行。该方法500可以包括步骤S510-S520。
S510，终端设备接收系统信息，该系统信息包括针对其它终端设备的用于测量载波的参考信号的配置信息。
S520，该终端设备根据该系统信息对该参考信号进行测量。
本申请实施例的终端设备可以处于空闲态，当该终端设备接收到系统信息后，可以对其参考信号进行测量。
本申请实施例中的其它终端设备的配置信息中所测量的载波可以为较高频段上的载波，从而较高频段上的载波上的参考信号可以按需发送。作为一种示例，较高频段上的载波上的参考信号基于其它终端设备的调度请求(scheduling request，SR)，BSR，上行参考信号或上报信息中任何一种被触发发送。其中，该上报信息可以通过RRC信令传输；或者，该上报信息承载在上行控制信息(uplink control information，UCI)中；或者，该上报信息包括在SR中。进一步的，若该上报信息承载在UCI中，该上报信息可以包括在 UCI中的第一字段中，第一字段为UCI中的已有字段，或者，该上报信息包括在UCI中的第二字段中，第二字段为UCI中的新增字段。第一字段为UCI中的已有字段可以理解为上报信息复用了第一字段。可选地，较高频段可以为毫米波波段或者任何大于或等于4.9GHz以上的频段。
本申请中的终端设备所测量的载波与其它终端设备的配置信息中所测量的载波相同时，终端设备可以根据针对其它终端设备的用于测量载波的参考信号的配置信息对其自身的参考信号进行测量，可以节省资源。
