下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本公开的实施例提供了一种波段切换处理方法及装置，用以解决由于参与切换的波段数量大于存储器数量影响上行发送调度时序的问题
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的 原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1所示，本公开的实施例提供了一种波段切换处理方法，应用于终端，具体包括以下步骤：
步骤101、终端在波段数量大于所述终端能够存储的波段配置信息数量的情况下，确定进行波段切换的准备时间信息；
该实施例中，所述波段配置信息可以存储在所述终端的射频(Radio Frequency，RF)芯片中，例如：存储在所述RF芯片的存储器中。所述波段数量是指所述终端支持的切换波段的数量。所述终端支持3个或者4个波段之间的上行载波切换。所述波段数量大于所述终端能够存储的波段配置信息数量，例如：终端支持进行切换的波段是band-1、band-2和band-3，所述终端仅支持存储2个波段配置信息；或者，终端支持进行切换的波段是band-1、band-2、band-3和band-4，所述终端仅支持存储2个或者3个波段配置信息。
所述准备时间信息是指在所述波段数量大于所述终端能够存储的波段配置信息数量的情况下，终端进行波段切换需要的准备时间。以两个波段之间的切换为例，所述终端的结构模型和切换过程如图2所示，当前执行的是band-1和band-2之间的切换，在下一步基站调度在band-3上进行数据发送，为了使得终端在band-3上进行数据发送，需要将band-3的波段配置信息发送给RF(M1或者M2存储器)，然后再写入RF的硬件，在终端接收到band-3上的调度信令后，需要所述终端额外执行一个新的动作：即将band-3的波段配置信息从基带芯片发送到射频芯片，即进行band-3配置参数的加载，执行该动作的时间信息称为所述准备时间信息。
步骤102、所述终端根据所述准备时间信息，确定所述波段切换的切换条件，和/或，确定所述波段切换完成后的上行调度限制条件；
其中，所述终端能够存储的波段配置信息数量默认等于2。
可选的，当终端的存储器个数为N2时，终端可以不用上报，所述网络侧设备和终端默认为具有2个存储器。
所述终端确定所述准备时间信息后，确定在波段数量大于所述终端能够存储的波段配置信息数量的情况下的切换条件和/或上行调度限制条件，例如：在4波段的切换中，针对终端仅支持存储2或者3个波段配置信息的情况， 确定band切换后的上行调度的限制条件；在3波段的切换中，针对终端仅支持存储2个波段配置信息的情况，确定band切换后的上行调度的限制条件。
本公开的实施例，终端确定在波段数量大于所述终端能够存储的波段配置信息数量的情况下的波段切换准备时间信息，并根据所述准备时间信息确定波段切换的切换条件和/或上行调度限制条件，有利于多波段的上行切换更高效的执行，提高切换效率。
需要说明的是，在实际上行传输中，信息或者数据的传输，是在载波(carrier)上行执行，而载波又属于一个特定的band。在本公开的实施例中，band切换也包含“band中的载波切换”的含义。同时“band参数配置”也包含“band中的载波参数配置”。
作为一个可选实施例，所述在波段数量大于所述终端能够存储的波段配置信息数量的情况下，确定进行波段切换的准备时间信息，包括：
若第一上行传输对应的波段数量和第二上行传输对应的波段数量之和，大于所述终端能够存储的波段配置信息数量，则确定执行所述第二上行传输需要所述准备时间；
确定所述准备时间的时长和所述准备时间的起始时间。
该实施例中，所述第一上行传输是原上行传输，所述第二上行传输可以是基站调度的所述第一上行传输的下一个上行传输，即所述第一上行传输是所述终端已经存储了波段配置信息的波段执行的上行传输，所述第二上行传输有至少一个波段的波段配置信息未存储。例如：当前执行发送切换的波段是band-1和band-2，即在所述band-1和band-2上进行的是所述第一上行传输；下一步基站调度在band-3上进行数据发送，则在所述band-3上进行的是所述第二上行传输；若所述终端仅能存储2个波段配置信息，则需要将存储的band-1的波段配置信息或者存储的band-2的波段配置信息删除，替换为所述band-3的波段配置信息，假设将band-2的波段配置信息删除，则终端存储band-1的波段配置信息和band-3的波段配置信息，band-1和band-3可以作为所述第二上行传输的切换波段对。
在所述第一上行传输对应的波段数量和第二上行传输对应的波段数量的总和，大于所述终端能够存储的波段配置信息数量的情况下，该切换场景需 要所述准备时间。所述终端进一步确定该切换场景所需的准备时间的时长(a_prepare_time)和起始时间(start)。
其中，所述第一上行传输对应的波段数量和第二上行传输对应的波段数量之和不包含重复的波段数量。例如：所述第一上行传输对应的原波段包括：band-1和band-2，即band-1和band-2之间执行第一上行传输的发送切换；第二上行传输对应的目标波段是band-1和band-3，即在替换掉band-2存储的波段配置信息后，band-1和band-3之间执行第二上行传输的发送切换，则所述第一上行传输对应的波段数量和第二上行传输对应的波段数量之和记为3(重复的两个band-1仅统计1个)。
可选的，所述需要准备时间的切换场景可以包括：
场景1：例如：当前执行发送切换(即所述第一上行传输)的是第一band和第二band,下一个上行传输(即所述第二上行传输)为第三band；终端仅能够存储2个波段配置信息；
场景2：例如：当前执行发送切换的是第一band和第二band，下一个上行传输为第三band和第四band，终端仅能够存储2个或者3个波段配置信息。
该实施例中，所述准备时间的引入，会对UE上行发送产生新的约束和影响，为了减少对整个UE的上行调度的影响，所述终端识别需要所述准备时间的切换场景。假设终端的射频芯片中，能够存储两个波段配置信息，例如所述射频芯片中包括两个用于存储射频配置参数的存储器M1和M2。其中M1和M2能够各自存储一个band的参数配置，因而需要所述准备时间的切换场景，依赖终端在射频芯片中能够存储的波段配置信息的个数。
作为一个可选实施例，通过以下至少一项确定所述波段数量大于所述终端能够存储的波段配置信息数量：
场景1-1：若所述第一上行传输对应的波段是第一波段和第二波段，第二上行传输对应的波段是第三波段，且所述终端能够存储的波段配置信息数量是两个，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
例如：当前执行发送切换(即所述第一上行传输)的为第一band和第二band，当下一个上行传输(即所述第二上行传输)为第三band，则波段数量是3，终端能够存储2个波段配置信息数量，则波段数量大于终端能够存储 的波段配置信息数量。在此场景中，存储器M1和M2分别存储着第一band和第二band波段配置信息。当调度信令指示下一个上行传输切换到第三band时，需要使用M1或者M2加载第三band的射频配置信息，因而需要所述准备时间。
例如：所述第一band、第二band和第三band分别记为：band-1、band-2、band-3，该场景下的波段切换如图3所示。
场景1-2：若所述第一上行传输对应的波段是第一波段和第二波段，所述第二上行传输对应的波段是第三波段和第四波段，且所述终端能够存储的波段配置信息数量是两个，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
当前执行发送切换(即所述第一上行传输)的为第一band和第二band，当下一个上行传输(即所述第二上行传输)为第三band和第四band，则所述波段数量是4，终端能够存储的波段配置信息数量是2，则波段数量大于终端存储的波段配置信息数量。在此场景中，存储器M1和M2分别存储着第一band和第二band的射频配置信息。当下一个上行传输切换到第三band和第四band(即第三band和第四band执行发送切换)时，需要使用M1和M2加载所述第三band及第四band的射频配置信息，因而需要所述准备时间。
例如：所述第一band、第二band、第三band和第四band分别记为：band-1、band-2、band-3、band-4，该场景下的波段切换如图4所示。
场景2-1：若所述第一上行传输对应的波段是第一波段和第二波段，所述第二上行传输对应的波段是第四波段，且所述终端能够存储的波段配置信息数量是三个，且所述终端已经存储所述第一波段、所述第二波段以及第三波段的配置信息，则确定所述波段数量大于所述终端存储的波段配置信息数量。
例如：当终端的射频芯片中有M1、M2、M3三个存储器时，假设当前执行发送切换的为第一band和第二band，三个存储器M1、M2和M3保存的波段配置参数分别为第一band、第二band和第三band的配置参数时，下一个上行传输只包括第四band，则波段数量是4(因为当前终端已经存储了三个波段的波段配置信息)，则波段数量大于终端存储的波段配置信息数量。在此场景重，M1、M2和M3分别存储着第一band、第二band、第三band的 波段配置信息。当下一个上行传输切换第四band时，需要使用M1、M2和M3中的任意一个存储器加载第四band的波段配置信息，因而需要所述准备时间。
场景2-2：若所述第一上行传输对应的波段是第一波段和第二波段，所述第二上行传输对应的波段是第三波段和第四波段，且所述终端能够存储的波段配置信息数量是三个，且所述终端已经存储所述第一波段、所述第二波段以及第三波段或者第四波段的配置信息，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
例如：当终端的射频芯片中有M1、M2、M3三个存储器时，当前执行发送切换的为第一band和第二band，三个存储器M1、M2、M3保存的波段配置参数分别为第一band、第二band和第三band的配置参数时，若下一个上行传输包含第三band和第四band，则波段数量是4，因此波段数量大于终端存储的波段配置信息数量，需要使用M1和M2中的任意一个存储器加载第四band的波段配置信息，因而需要所述准备时间。
上述场景1-1、场景1-2、场景2-1场景2-2为需要准备时间的切换场景。
需要说明的是，假设终端最多支持4个波段的发送切换，终端的射频芯片中有M1、M2、M3以及M4四个存储器，则不需要所述准备时间。
作为一个可选实施例，所述方法还包括：向网络侧设备发送第一能力信息；所述第一能力信息包括所述终端能够存储的波段配置信息数量。
该实施例中，对于不同终端能力，需要所述准备时间的切换场景不同，终端可以将相关需求上报给网络侧设备，以便所述网络侧设备和终端能够对于切换场景有统一的理解。
以所述终端能够存储的波段配置信息数量是所述终端包含的存储器个数为例，所述终端向网络侧设备上报存储器的数量，例如：终端上报存储器的能力参数可以包括：numOfMemory{N2，N3，N4}。其中N2表示有2个用于保存波段参数配置的存储器，N3表示有3个存储器，N4表示有4个存储器。网络侧设备和终端根据上报的存储器的个数，判断需要所述准备时间的切换场景。如上报N2时，为上述的场景1-1和场景1-2；上报N3时，为上述的场景2-1和场景2-2。
可选的，当终端的存储器个数为N2时，终端可以不用上报，所述网络侧设备和终端默认为具有2个存储器。
作为一个可选实施例，所述方法还包括：向网络侧设备发送第二能力信息，所述第二能力信息指示需要准备时间的条件。
该实施例中，所述需要准备时间的条件可以是：波段数量大于终端能够存储的波段配置信息数量，确定需要准备时间的条件的方式即为确定波段数量大于所述终端能够存储的波段配置信息数量的方式。波段数量大于所述终端能够存储的波段配置信息数量的切换场景可以包括上述场景1-1、场景1-2、场景2-1、场景2-2中的一项或者多项。
所述终端向网络侧设备上报需要准备时间的条件，即为向所述网络侧设备上报需要所述准备时间的切换场景，使所述网络侧设备能够和所述终端对于切换过程的理解一致。
例如：所述终端指示需要所述准备时间的切换场景为：numOfAddtionalPreTime{Case1-1&1-2，Case1-2，case-2-1}。其中Case1-1&1-2表示上述的场景1-1和场景1-2的波段切换需要所述准备时间。假如上报Case2-1，表示上述的场景2-1需要所述准备时间。
可选的，对于Case1-1&1-2，终端可以不上报，即网络侧设备和终端默认为上述的场景1-1和场景1-2需要所述准备时间。
需要说明的是，本公开实施例的第一band、第二band、第三band、第四band，并不是指band的编号，只是用于表示不同的band，也可以表示为：第一载波，第二载波等。
作为一个可选实施例，所述方法还包括：通过以下一种方式确定执行所述第二上行传输的切换波段对(band-pair)；
(1)：接收网络侧设备发送的指示信息，根据所述指示信息确定执行所述第二上行传输的切换波段对。
(2)基于预定义的规则，确定执行所述第二上行传输的切换波段对。
所述第二上行传输对应的切换载波对，是对第一上行传输的切换载波对进行替换后的获得的新的band-pair。在上行发送切换中，在终端存储的波段配置信息中，如果没有新的上行传输(即所述第二上行传输)对应的波段配 置信息时，需要加载该band射频配置参数，并删除掉当前已经保存的band的射频配置参数。在替换相应band配置信息后，在终端形成了新的切换band对，在这些新的切换band对中，本次切换之后再执行的band切换不需要所述准备时间。
该实施例中，所述终端可以根据网络侧设备的指示确定新的切换波段对，也可以基于预定义的规则确定新的切换波段对。
可选的，所述指示信息或者所述预定义规则用于指示以下一项：
1)所述第一上行传输对应的波段中不允许被替换的波段。所述网络侧设备可以通过所述指示信息指示所述第一上行传输的波段中不允许被删除或者被替换的波段参数，则相应的波段不允许被删除或者替换。或者，所述终端可以根据预定义规则确定哪些波段不允许被删除或者替换。
2)所述第一上行传输对应的波段中允许被替换的波段；即所述网络侧设备可以通过所述指示信息指示所述第一上行传输的波段中被删除或者被替换的波段参数，则相应的波段被删除或者替换。或者，所述终端可以根据预定义规则确定哪些波段可以被删除或者替换。
3)所述第二上行传输的切换波段对，所述第二上行传输的切换波段对中包含所述第一上行传输对应的波段和/或所述第二上行传输对应的波段。所述终端可以基于网络侧设备的指示信息或者预定义规则确定所述第二上行传输的切换波段对，所述第二上行传输的切换波段对可以是由第一上行传输的波段和第二上行传输的波段共同组成，也可以是由第二上行传输的多个波段组成。
该实施例中，在上行发送切换中，若终端没有存储新的上行传输的波段配置信息，则需要加载该新的band配置参数，并删除掉当前已经存储的一个band的射频参数。本实施例根据基站配置的指示信息，确定删除或者被替换的band配置信息(简称被替换的band)。
所述波段配置信息被替换的过程可以理解为如下：
(1)在band配置信息替换前：存储器中记录的多个波段配置信息的band之间，可以直接进行上行切换，而无需所述准备时间。
例如：M1中存储band-1的配置参数，M2中存储band-2的配置参数。 则band-1和band-2之间做切换，不需要所述准备时间，band-1和band-2称为一个切换band对：band-pair(band-1，band-2)。
(2)在band配置参数替换后：如M1的band-1参数，被band-3替换，则：
如果发生Band-1和band-2之间的切换，不能直接进行，需要所述准备时间；
如果发生Band-3和band-2之间的切换，可以直接进行上行切换，无需所述准备时间，则新的切换band对为：band-pair(band-3，band-2)。
下面通过实施例举例说明基于网络侧设备发送的指示信息确定所述第二上行传输的切换波段对。
方式一：
(1)基站配置一个不可被替换的band(假设UE可以存储2个波段配置信息，例如有2个存储器)。
基站通过高层信令或者物理层信令，配置一个不可被替换的band，即该band的配置参数一直占有其中一个存储器(终端不能根据上行调度信令进行修改)，另外一个存储器的参数可以被其他band配置参数进行替换，即可以根据上行调度信令进行修改，并形成新的切换band对。
例如：基站通过如下信令配置一个主band(即不可被替换的band)：
Master-band-carrier ENUMERATED{B1，B2，B3，B4}；其中，ENUMERATED为枚举类型，假设配置为B1时，则认为是band-1对应的配置参数不可替换，在组成新的切换band对时，band-1作为其中一个band；则在UE端，当需要所述准备时间的切换场景出现时，终端确定被替换波段配置参数的band如表1所示：
表1：基于不可替换band的配置信息

如上述表1所示，band-1的配置信息不允许被替换，在第一上行传输的切换波段对是band-1和band-2，第二上行传输在band-3上进行发送时，将存储的band-2的配置信息替换为band-3的配置信息，则第二上行传输的切换波段对是band-1和band-3；在第一上行传输的切换波段对是band-1和band-3，第二上行传输在band-2上进行发送时，将存储的band-3的配置信息替换为band-2的配置信息，则第二上行传输的切换波段对是band-1和band-2；在第一上行传输的切换波段对是band-1和band-4，第二上行传输在band-3上进行发送时，将存储的band-4的配置信息替换为band-3的配置信息，则第二上行传输的切换波段对是band-1和band-3。
(2)基站配置2个不可被替换的band(假设UE可以存储3个波段配置信息，例如有3个存储器)。
基站通过高层信令或者物理层信令，配置两个不可被替换的band，即该两个band的配置参数一直占有其中两个个存储器，另外一个存储器的参数可以被其他band参数进行替换。
如：基站通过如下信令配置两个band的主band(即不可被替换的band)：
Master-band-carrier-1ENUMERATED{B1,B2,B3,B4}；
Master-band-carrier-2ENUMERATED{B1,B2,B3,B4}；
其中，ENUMERATED为枚举类型，假设Master-band-carrier-1配置为B1时，Master-band-carrier-2配置为B2时，则认为是band-1和band-2对应的配置参数不可替换；则对于UE，当出现需要所述准备时间的切换场景时，终端确定被替换射频参数的band如表2所示。
表2：基于不可替换band的配置信息

如上述表2所示，band-1和band-2的配置信息不允许被替换，在第一上行传输的切换波段对是band-1和band-2，第二上行传输在band-4上进行发送时，将存储的band-3的配置信息替换为band-4的配置信息，则第二上行传输的切换波段对是band-1、band-2、band-4任意两两组合，其他切换场景类似，在此不做赘述。
方式二：基站配置被替换的band。
定义进行band切换的两个波段为“切换band对”(切换对(switching pair))，当出现需要所述准备时间的切换场景时，基站配置当前“切换band对”中的哪一个band的RF配置参数被替换。
可选的，基站配置内容包括如下三个信息：
1)当前“切换band对”信息：执行当前UE上行发送切换的两个band信息。
2)将要传输的band信息
3)被替换的band信息：指下一次上行发送的band中，至少有一个band不是“切换band对”中的任意一个时，需要被刷新/替代的band。
以终端具有2个存储器，即终端能够存储2个波段配置信息为例，基站配置的被替换的band如表3所示。
表3：基于“切换band对”的替换band(2个存储器)

如上述表3所示，行序号1-6的切换场景是，下一次上行发送仅仅在一个band时的情况，即只有1T(1通道)的传输的情况下，基站指示的被替换配置参数的band。
例如：行序号1中，当前(所述第一上行传输)的切换波段对是band-1和band-2，存储器分别存储band-1和band-2的配置信息。第二上行传输将要在band-3或者band-4上进行发送，基站配置band-1的配置信息允许被替换，则可以将MI存储的band-1的配置信息替换为band-3或者band-4的配置信息。
行序号7：下一次上行发送在2个band时的情况(即支持1P+1P的状态)，且和当前上行发送切换对的band均不同。则终端默认替换所有当上行发送切换对的所有配置参数。
如表3中的行序号7所示，当前(所述第一上行传输)的切换波段对是band-1和band-2，存储器分别存储band-1和band-2的配置信息。第二上行传 输将要在band-3和band-4上进行发送，基站配置band-1和band-2的配置信息均允许被替换，则可以将MI存储的band-1的配置信息和M2存储的band-1的配置信息替换为band-3和band-4的配置信息。
行序号8：下一次上行发送在2个band时的情况(即支持1P+1P的状态)，且有一个band和当前上行发送的切换波段对的band中的一个相同。则终端默认替换当上行发送切换对中不发送的band参数。
如表3中的行序号8所示，当前(所述第一上行传输)的切换波段对是band-1和band-2，存储器分别存储band-1和band-2的配置信息。第二上行传输将要在band-2和band-4上进行发送，与当前上行传输具有相同的发送band-2，则基站配置band-1的配置信息允许被替换，则可以将MI存储的band-1的配置信息替换为band-4的配置信息。
以终端具有3个存储器，即终端能够存储3个波段配置信息为例，基站配置的被替换的band如表4所示。
表4：基于“切换band对”的替换band(3个存储器)
如上述表4所示，对于行序号1：下一次上行发送在2个band(band-4和band-3)时的情况(即支持1P+1P的状态)，且和当前上行发送切换波段对的band均不同，基站指示band-1的波段配置参数被替换。
对于行序号2：下一次上行发送不属于行序列号1的情况下，替换不属于当前上行发送切换波段对中的band参数(即band-3)。
方式三：基站配置第二上行传输的切换波段对，即基站指示形成哪些新的切换band对。
可选的，基站配置内容包括如下三个信息：
1)当前“切换band对”信息：执行当前UE上行发送切换band对的信息。
2)将要传输band的信息。
3)新的切换band对：当前上行发送切换对中的哪一个band和将要传输的band形成切换波段对。
以终端具有2个存储器，即终端能够存储2个波段配置信息为例，基站配置的切换波段对如表5所示。
表5：基于形成“新的切换band对”(2个存储器)
如上述表5所示，行序号1至12的切换场景是，下一次上行发送仅仅在一个band时的情况，即只有1T(1通道)的传输的情况下，基站指示形成新的切换band对。
例如行序号1所示，当前(所述第一上行传输)的切换波段对是band-1和band-2。第二上行传输将要在band-3上进行发送，基站指示新的切换band对是band-1和band-3，即将已经存储的band-2的配置信息替换为band-3的配置信息。
行序号13至14：下一次上行发送在2个band时的情况(即支持1P+1P的状态)，则形成新的band切换对默认为将要做上行发送的2个band。
例如行序号13所示，当前(所述第一上行传输)的切换波段对是band-3和band-4。第二上行传输将要在band-2和band-3上进行发送，基站指示新的切换band对是band-2和band-3，即将已经存储的band-4的配置信息替换为band-3的配置信息。
以终端具有3个存储器，即终端能够存储3个波段配置信息为例，基站配置的切换波段对如表6所示。
表6：基于形成“新的切换band对”(3个存储器)

如上述表6所示，行序号1：表示当前上行传输是band-1、band-2、band-3任意两个band组合的切换波段对时，新的切换band对为band-1、band-3、band-4的任意两个组合，即相当于替换band-2的配置参数。
下面通过具体实施例说明终端基于预定义规则确定第二上行传输的切换波段对的方法。
作为一个可选实施例，所述预定义规则通过以下方式之一指示所述第一上行传输的波段中允许被替换的波段：
方式一：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量与所述第一上行传输对应的波段数量相同，则所述第一上行传输对应的每个波段均允许被替换；
该实施例中，所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，可以是指第二上行传输所有的波段均与第一上行传输的波段不同，例如第一上行传输的切换波段是band-1和band-2，第二上行传输的切换波段是band-3和band-4。则当前执行band切换的两个band(如band-1和band-2)的配置信息，均被替换。
方式二：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量，则根据所述第一上行传输对应的波段的结束时间和/或开始时间确定允许被替换的波段。
所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，可以是所述第二上行传输对应的波段与所述第一上行传输对应的波段完全不同或者部分不同，所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量是指：所述第二上行传输对应的波段的总数量小于所述第一上行传输对应的波段的总数量。例如：第一上行传输的切换波段是band-1和band-2，第二上行传输的切换波段是band-3或者band-4。则根据所述原波段的结束时间和/或开始时间确定哪个band被替换。
可选的，根据所述第一上行传输对应波段的结束时间和/或开始时间确定允许被替换的波段，包括：
若所述第一上行传输对应的每个波段的结束时间或者开始时间均相同，则确定第一目标编号的波段允许被替换；否则，确定开始时间最早或者结束时间最早的波段允许被替换。
该实施例中，所述第一目标编号可以是编号最小或者最大的编号，也可以为其他预定编号。在所述第二上行传输对应波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量时，如果当前切换band对的结束时间或者开始时间均相同(例如band-1的结束时间和band-2的结束时间相同，或者，band-1的开始时间和band-2的开始时相同)，则可以选择编号最小的band的配置信息被替换，或者，可以选择编号最大的band的配置信息被替换。
如果不满足所述第一上行传输对应的每个波段的结束时间或者开始时间均相同，则确定开始时间最早或者结束时间最早的波段允许被替换。例如：选择最早开始或者最早结束的band，进行相应的band配置信息替换。
作为一个可选实施例，所述预定义规则通过以下方式之一指示所述第二上行传输的切换波段对：
方式1：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量与所述第一上行传输对应的波段数量相同，则确定所述第二上行传输对应的波段为所述切换波段对；
该实施例中，可以根据预定义规则确定第二上行传输对应的切换波段对。例如第一上行传输的切换波段是band-1和band-2，第二上行传输的切换波段是band-3和band-4，则所述第二上行传输待发送的band-3和band-4组成所述切换波段对。
方式2：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量，则根据所述第一上行传输对应的波段的结束时间和/或开始时间确定所述切换波段对。
可选的，根据所述第一上行传输对应的波段的结束时间和/或开始时间确 定所述切换波段对，包括：
若所述第一上行传输对应的每个波段的结束时间或者开始时间均相同，则将第二目标编号的波段与所述第二上行传输对应的波段确定为所述切换波段对；
否则，将开始时间最早或者结束时间最早的波段与所述第二上行传输对应的波段确定为所述切换波段对。
该实施例中，所述第二目标编号可以是最小或者最大的编号，也可以为其他预定编号，在此不做限定。在所述第二上行传输对应的波段与所述第一上行传输对应波段不同，且所述第二上行传输对应波段数量小于所述第一上行传输对应的波段数量时，如果当前切换band对的结束时间或者开始时间均相同(例如band-1的结束时间和band-2的结束时间相同，或者，band-1的开始时间和band-2的开始时相同)，则可以选择编号最小的band与第二上行传输对应的波段组成所述切换波段对，例如：第二上行传输的波段是band-3，则选择band-1和所述band-3组成所述第二上行传输的切换波段对。
可选的，也可以选择编号最大的band与目标波段组成所述切换波段对，例如：第二上行传输的波段是band-3，则选择band-2和所述band-3组成所述第二上行传输的切换波段对。
如果不满足所述第一上行传输对应的波段中的每个波段的结束时间或者开始时间均相同，则确定开始时间最早或者结束时间最早的波段与待传输的band组成新的切换波段对。
作为一个可选实施例，所述确定所述准备时间的时长和所述准备时间的起始时间，包括：
确定所述准备时间的时长为参考子载波间隔(Subcarrier Spacing，SCS)的预定倍数，所述参考SCS是网络侧设备配置的参与载波切换的最大SCS数值；例如：1倍、1/2倍。其中参考SCS为网络侧设备配置的参与载波切换的最大SCS数值。
根据所述第一上行传输被替换的波段上的符号发送时间，确定所述准备时间的最早起始时间。
该实施例中，在确定波段切换的所述准备时间时，需要确定所述准备时 间的时长和最早起始时间。其中，所述准备时间的时长可以是一个参考SCS的预定倍数，例如：所述准备时间的时长是一个参考SCS。
以两个载波之间的上行切换为例，如图2所示，基带处理器通过控制接口C1和C2，将射频芯片需要的RF配置参数写入RF硬件部分：
1)：基带处理器通过控制接口C1，将配置信息发送到RF芯片的M1和M2存储器中。
通常的，为了节省RF芯片的功率耗费，控制接口C1不是实时的，而是一定的周期进行数据传输，如图2所示，每隔一个时隙(如0.5ms)进行一次数据的传输。由于存储器个数的限制，两个存储器M1和M2最多同时存储2个band的射频配置信息。
需要说明的是：RF参数配置过程可以提前发送到M1和M2，如：如果M1空闲，则可以提前多个时隙把RF的配置信息通过控制接口C1发到M1。
2)M1/M2通过控制接口C2，将RF配置信息配置到硬件部分。
此过程，需要在数据发送前将配置信息写入到射频的硬件部分，提前量可以为一个切换时间(switching period)，如数值为{35us,140us,210us}中的一个。
所述准备时间的时长a_prepare_time可以为一个参考时隙的时长，该参考时隙可以定义为参与切换的多个band的载波中，SCS为最大的时隙长度。比如：参与多个band切换的载波为：载波1的SCS＝15KHz(时隙长度1ms)，载波2的SCS＝30KHz(时隙长度0.5ms)，载波3的SCS＝60KHz(时隙长度0.25ms)，则参考的SCS为SCS＝60KHz，即所述准备时间的时长a_prepare_time为0.25ms。
可选的，所述准备时间的时长a_prepare_time也可以为参考时长的1/2或者1/4倍数，在此不做限定。
作为一个可选实施例，所述确定所述准备时间的时长和所述准备时间的起始时间，包括以下一项：
1)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送第一个符号的起始时间；
假设UE准备替换存储band C的波段配置信息，则所述准备时间的起始 始时间可以描述为：在band C上进行发送的第一个符号的起始时间。
2)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送第一个符号的起始时间与波段切换时间的差值。
假设UE准备替换存储band C的波段配置信息，则所述准备时间的起始时间可以描述为：在band C上进行发送的第一个符号的起始时间减去“波段切换时间”，即相对于1)，再提前一个波段切换时间。
可选的，所述波段切换时间(switching period)，数值候选为{35us,140us,210us}，具体数值由终端在能力上报中指示给网络侧设备。在波段切换时间内，终端不能发送任何数据，即数据的发送是中断的。
3)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送最后一个符号的结束时间。
该实施例中，如果射频芯片中，没有控制接口C2，即只要基带芯片将数据发送给射频芯片，该射频配置信息即刻写入射频的硬件部分。假设UE准备替换存储band C的波段配置信息，则起始时间start确定方法可以描述为：在bandC上进行发送的最后一个符号的结束时间。
作为一个可选实施例，所述切换条件包括：
第一上行传输对应的波段切换时间与第二上行传输对应的波段切换的时间之间的差值大于或者等于所述准备时间的时长。
该实施例中，所述切换条件时终端期望调度的上行发送需要满足的切换条件。其中，两次连续的上行切换之间的时时长需要大于或者等于a_prepare_time。
如图5所示，假设当前切换band对是band 1和band 2，两个band的最近一次切换是在t1，将要发送的是band 3上的载波，且由此产生的上行切换场景在t2，t1和t2之间的间隔为d，d的时间不小于所述准备时间a_prepare_time。
需要说明的是，在该实施例中，所述准备时间a_prepare_time的时长不包含波段切换时间(switching period)，主要考虑因素是“需要所述准备时间的切换场景”是特殊情况，不具有普遍性，但切换时间是在载波切换中必要的内容。可选的，所述准备时间a_prepare_time的时长也可以包含波段切换 时间。
可选的，如果两个连续的上行波段(或者载波)切换均需要准备时间，则这两个连续的上行切换间隔不小于a_prepare_time的时长。
其中，2P是指使用2个发送通道(也称为两个天线端口)进行发送。1P是指使用1个发送通道(也称为1个天线端口)进行发送。
作为一个可选实施例，所述上行调度限制条件，包括：
终端进行第二上行传输时的上行发送时间是第一时间或者晚于所述第一时间；
其中，所述第一时间是：所述准备时间的起始时间、所述准备时间的时长以及波段切换时长之和；
或者，
所述第一时间是：网络侧设备的调度信令的接收时间、所述准备时间的时长、所述调度信令的解析时间以及载波切换时长之和。
该实施例中，当基站在某一时刻(如t0)发送调度信令下行控制信息(Downlink Control Information，DCI)时，终端需要进行调度信令的检测以及信令解析。此过程需要一个处理时间(即DCI解析时间DCI_decoding_time)，则相应的需要满足上行调度限制条件。
条件1：所述准备时间是a_prepare_time，所述准备时间的起始时间为start_time0，则所述第二上行传输的上行发送时间不早于：
所述准备时间的起始时间(start_time0)+准备时间的时长(a_prepare_time)+波段切换时长(switching-period)。
如图6所示，终端接收基站发送的调度信令，指示在t3时刻进行上行发送。在t3时刻上行发送时，需要进行一次band上行发送切换，该切换场景需要所述准备时间。假设所述准备时间的起始时间为start_time0(即开始更新band-3的RF配置参数)，则start_time0和t3之间的时间不小于a_prepare_time与波段切换时间之和。
需要说明的是，如果a_prepare_time包含波段切换时间，则该上行调度限制条件可以描述为：start_time0和t3之间的时间不小于a_prepare_time。
所述上行调度限制条件还可以描述为：start_time0和t2之间的时间不小 于a_prepare_time，其中t2为将要传输的band的切换开始时间。
条件2：所述准备时间是a_prepare_time，调度信令的接收时间为t0，则所述第二上行传输的上行发送时间不早于：
调度信令的接收时间(t0)+准备时间的时长(a_prepare_time)+DCI解析时间(DCI_decoding_time)+波段切换时长(switching-period)。
如图7所示，终端在t0时刻检测基站发送的调度信令，指示在t3时刻进行上行发送。在t3时刻上行发送时，需要进行一次band上行发送切换，该切换场景需要所述准备时间。则t0和t3之间的时间不小于：
t0+a_prepare_time+DCI_decoding_time+switching-period。
可选的，如果a_prepare_time包含波段切换时间，则所述上行调度限制条件可以描述为：start_time0和t3之间的时间不小于a_prepare_time+DCI_decoding_time。
可选的，如果当前协议确定的t0到t3的时间不小于current-process-time。则当发生的波段切换需要准备时间(a_prepare_time)时，则t0和t3之间的时间不小于：
max(t0+a_prepare_time+DCI_decoding_time+switching-period，current-process-time)，max()表示取最大数值。
如果a_prepare_time包含波段切换时间，则所述上行调度限制条件可以描述为：start_time0和t3之间的时间不小于a_prepare_time+DCI_decoding_time。
当基站调度终端发送一个上行传输时，也需要准备时间，这个时间称为第一上行发送准备时间(current-process-time)或者第一上行准备时间。第一上行准备时间和本公开实施例的所述准备时间在UE端是串行时(即无法同时执行)，t0和t2之间的时间不小于t0+a_prepare_time+current-process-time。
本公开的实施例，终端识别需要所述准备时间的切换场景，并确定新上行传输的切换band对；确定所述准备时间的时长a_prepare_time以及起始时间start。根据a_prepare_time和start确定切换条件和/或上行调度的限制条件，有利于多波段的上行切换更高效的执行，提高切换效率。
如图8所示，本公开实施例还提供一种波段切换处理方法，应用于网络 侧设备，包括：
步骤801、网络侧设备在波段数量大于终端能够存储的波段配置信息数量的情况下，确定所述终端进行波段切换的准备时间信息；
该实施例中，所述终端能够存储的波段配置信息数量可以是终端上报至所述网络侧设备的。所述波段数量是指支持的切换波段的数量，例如：所述终端支持3个或者4个波段之间的上行载波切换。所述波段数量大于所述终端能够存储的波段配置信息数量，例如：终端支持进行切换的波段是band-1、band-2和band-3，所述终端仅支持存储2个波段配置信息；或者，终端支持进行切换的波段是band-1、band-2、band-3和band-4，所述终端仅支持存储2个或者3个波段配置信息。
所述准备时间信息是指在所述波段数量大于所述终端能够存储的波段配置信息数量的情况下，终端进行波段切换需要的准备时间。以两个波段之间的切换为例，所述终端的结构模型和切换过程如图2所示，当前执行的是band-1和band-2之间的切换，在下一步基站调度在band-3上进行数据发送，为了使得终端在band-3上进行数据发送，需要将band-3的波段配置信息发送给RF(M1或者M2存储器)，然后再写入RF的硬件，在终端接收到band-3上的调度信令后，需要所述终端额外执行一个新的动作：即将band-3的波段配置信息从基带芯片发送到射频芯片，即进行band-3配置参数的加载，执行该动作的时间信息称为所述准备时间信息。
步骤802、所述网络侧设备根据所述准备时间信息，确定所述波段切换的切换条件，和/或，确定所述波段切换完成后的上行调度限制条件；
其中，所述终端能够存储的波段配置信息数量默认等于2。
该实施例中，所述网络侧设备确定所述准备时间信息后，确定在波段数量大于所述终端能够存储的波段配置信息数量的情况下的切换条件和/或上行调度限制条件，所述网络侧设备在调度上行传输时满足所述终端期望的上行调度限制条件。例如：在4波段的切换中，针对终端仅支持存储2或者3个波段配置信息的情况，确定band切换后的上行调度的限制条件；在3波段的切换中，针对终端仅支持存储2个波段配置信息的情况，确定band切换后的上行调度的限制条件。
本公开的实施例，网络侧设备确定在波段数量大于终端能够存储的波段配置信息数量的情况下的波段切换准备时间信息，并根据所述准备时间信息确定波段切换的切换条件和/或上行调度限制条件，所述网络侧设备调度终端的上行传输时，满足所述上行调度限制条件，有利于多波段的上行切换更高效的执行，提高切换效率。
作为一个可选实施例，所述在波段数量大于所述终端能够存储的波段配置信息数量的情况下，确定进行波段切换的准备时间信息，包括：
若第一上行传输对应的波段数量和第二上行传输对应的波段数量之和，大于所述终端能够存储的波段配置信息数量，则确定执行所述第二上行传输需要所述准备时间；
确定所述准备时间的时长和所述准备时间的起始时间。
该实施例中，所述第一上行传输是所述网络侧设备调度的原上行传输，所述第二上行传输是所述网络侧设备调度的所述第一上行传输的下一个上行传输，即所述第一上行传输是所述终端已经存储了波段配置信息的波段执行的上行传输，所述第二上行传输有至少一个波段的波段配置信息未存储。例如：当前执行发送切换的波段是band-1和band-2，即在所述band-1和band-2上进行的是所述第一上行传输；下一步基站调度在band-3上进行数据发送，则在所述band-3上进行的是所述第二上行传输；若所述终端仅能存储2个波段配置信息，则需要将存储的band-1的波段配置信息或者存储的band-2的波段配置信息删除，替换为所述band-3的波段配置信息，假设将band-2的波段配置信息删除，则终端存储band-1的波段配置信息和band-3的波段配置信息，band-1和band-3可以作为所述第二上行传输的切换波段对。
在所述第一上行传输对应的波段数量和第二上行传输对应的波段数量的总和，大于所述终端能够存储的波段配置信息数量的情况下，该切换场景需要所述准备时间。所述网络侧设备进一步确定该切换场景所需的准备时间的时长(a_prepare_time)和起始时间(start)。
作为一个可选实施例，所述方法还包括：
接收所述终端发送的第一能力信息，所述第一能力信息包括所述终端能够存储的波段配置信息数量；
和/或，接收所述终端发送的第二能力信息，所述第二能力信息指示执行波段切换需要所述准备时间的条件。
该实施例中，对于不同终端能力，需要所述准备时间的切换场景不同，终端可以将相关需求上报给网络侧设备，以便所述网络侧设备和终端能够对于切换场景有统一的理解。
所述终端还可以向所述网络侧设备上报需要所述准备时间的条件，使所述网络侧设备能够和所述终端对于切换过程的理解一致。
例如：所述终端指示需要所述准备时间的切换场景为：numOfAddtionalPreTime{Case1-1&1-2，Case1-2，case-2-1}。其中Case1-1&1-2表示上述的场景1-1和场景1-2的波段切换需要所述准备时间。假如上报Case2-1，表示上述的场景2-1需要所述准备时间。
作为一个可选实施例，通过以下至少一项确定所述波段数量大于所述终端能够存储的波段配置信息数量：
场景1-1：若所述第一上行传输对应的波段是第一波段和第二波段，第二上行传输对应的波段是第三波段，且所述终端能够存储的波段配置信息数量是两个，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
例如：当前执行发送切换(即所述第一上行传输)的为第一band和第二band，当下一个上行传输(即所述第二上行传输)为第三band，则波段数量是3，终端能够存储2个波段配置信息数量，则波段数量大于终端能够存储的波段配置信息数量。；在此场景中，存储器M1和M2分别存储着第一band和第二band波段配置信息。当调度信令指示下一个上行传输切换到第三band时，需要使用M1或者M2加载第三band的射频配置信息，因而需要所述准备时间。
场景1-2：若所述第一上行传输对应的波段是第一波段和第二波段，所述第二上行传输对应的波段是第三波段和第四波段，且所述终端能够存储的波段配置信息数量是两个，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
当前执行发送切换(即所述第一上行传输)的为第一band和第二band，当下一个上行传输(即所述第二上行传输)为第三band和第四band，则所 述波段数量是4，终端能够存储的波段配置信息数量是2，则波段数量大于终端存储的波段配置信息数量。在此场景中，存储器M1和M2分别存储着第一band和第二band的射频配置信息。当下一个上行传输切换到第三band和第四band(即第三band和第四band执行发送切换)时，需要使用M1和M2加载所述第三band及第四band的射频配置信息，因而需要所述准备时间。
场景2-1：若所述第一上行传输对应的波段是第一波段和第二波段，所述第二上行传输对应的波段是第四波段，且所述终端能够存储的波段配置信息数量是三个，且所述终端已经存储所述第一波段、所述第二波段以及第三波段的配置信息，则确定所述波段数量大于所述终端能够存储的波段配置信息数量。
例如：当终端的射频芯片中有M1、M2、M3三个存储器时，假设当前执行发送切换的为第一band和第二band，三个存储器M1、M2和M3保存的波段配置参数分别为第一band、第二band和第三band的配置参数时，下一个上行传输只包括第四band，则波段数量是4(因为当前终端已经存储了三个波段的波段配置信息)，则波段数量大于终端存储的波段配置信息数量。在此场景重，M1、M2和M3分别存储着第一band、第二band、第三band的波段配置信息。当下一个上行传输切换第四band时，需要使用M1、M2和M3中的任意一个存储器加载第四band的波段配置信息，因而需要所述准备时间。

所述网络侧设备通过指示信息为所述终端配置所述第二上行传输的切换波段对的具体实现过程参见上述应用于终端的方法实施例，在此不做赘述。
可选的，所述网络侧设备可以基于预定义规则确定所述第二上行传输的切换波段对，包括：
方式一：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量与所述第一上行传输对应的波段数量相同，则所述第一上行传输对应的每个波段均允许被替换；
方式二：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量，则根据所述第一上行传输对应的波段的结束时间和/或开始时间确定允许被替换的波段。
具体的，若所述第一上行传输对应的每个波段的结束时间或者开始时间均相同，则确定第一目标编号的波段允许被替换；否则，确定开始时间最早或者结束时间最早的波段允许被替换。

方式2：若所述第二上行传输对应的波段与所述第一上行传输对应的波段不同，且所述第二上行传输对应的波段数量小于所述第一上行传输对应的波段数量，则根据所述第一上行传输对应的波段的结束时间和/或开始时间确定所述切换波段对。
具体的，若所述第一上行传输对应的每个波段的结束时间或者开始时间均相同，则将第二目标编号的波段与所述第二上行传输对应的波段确定为所述切换波段对；
否则，将开始时间最早或者结束时间最早的波段与所述第二上行传输对应的波段确定为所述切换波段对。
作为一个可选实施例，所述确定所述准备时间的时长和所述准备时间的起始时间，包括：
确定所述准备时间的时长为参考子载波间隔(Subcarrier Spacing，SCS)的预定倍数，所述参考SCS是网络侧设备配置的参与载波切换的最大SCS数值；例如：1倍、1/2倍。其中参考SCS为网络侧设备配置的参与载波切换的最大SCS数值。
根据所述第一上行传输被替换的波段上的符号发送时间，确定所述准备时间的最早起始时间。
该实施例中，在确定波段切换的所述准备时间时，需要确定所述准备时 间的时长和最早起始时间。其中，所述准备时间的时长可以是一个参考SCS的预定倍数，例如：所述准备时间的时长是一个参考SCS。
可选的，所述确定所述准备时间的时长和所述准备时间的起始时间，包括以下一项：
1)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送第一个符号的起始时间。
假设UE准备替换存储band C的波段配置信息，则所述准备时间的起始始时间可以描述为：在band C上进行发送的第一个符号的起始时间。
2)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送第一个符号的起始时间与波段切换时间的差值。

3)确定所述准备时间的最早起始时间是：所述第一上行传输被替换的波段上发送最后一个符号的结束时间。
该实施例中，如果射频芯片中，没有控制接口C2，即只要基带芯片将数据发送给射频芯片，该射频配置信息即刻写入射频的硬件部分。假设UE准备替换存储band C的波段配置信息，则起始时间start确定方法可以描述为：在bandC上进行发送的最后一个符号的结束时间。

需要说明的是，在该实施例中，所述准备时间a_prepare_time的时长不包含波段切换时间(switching period)，主要考虑因素是“需要所述准备时间的切换场景”是特殊情况，不具有普遍性，但切换时间是在载波切换中必要的内容。可选的，所述准备时间a_prepare_time的时长也可以包含波段切换 时间。
作为一个可选实施例，所述上行调度限制条件，包括：
终端进行第二上行传输时的上行发送时间是第一时间或者晚于所述第一时间；

该实施例中，当网络侧设备在某一时刻(如t0)发送调度信令DCI时，终端需要进行调度信令的检测以及信令解析。此过程需要一个处理时间(即DCI解析时间DCI_decoding_time)，则相应的需要满足上行调度限制条件。
条件1：所述准备时间是a_prepare_time，所述准备时间的起始时间为start_time0，则所述第二上行传输的上行发送时间不早于：
start_time0+a_prepare_time+switching-period。
条件2：所述准备时间是a_prepare_time，调度信令的接收时间为t0，则所述第二上行传输的上行发送时间不早于：
