技术领域
本公开实施例涉及通信技术领域，尤其涉及一种信号传输方法、设备及系统。
背景技术
用户设备(User Equipment，UE)的移动性过程，可以为UE发起目标小区切换，或UE发起辅助小区组(Secondary Cell Group，SCG)切换(change)的过程。其中，在UE处于移动性过程的情况下，UE可以发起随机接入过程。具体的，UE可以将随机接入请求消息承载在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)中发送给网络设备。网络设备接收到随机接入请求消息之后，可以向UE发送随机接入响应消息，以使得UE接入网络设备。
然而，在网络设备向UE发送随机接入响应消息时，网络设备可能在多个波束中向UE发送随机接入响应消息，但由于UE并不能确定网络设备在哪个波束上发送随机接入响应消息，因此可能会使得UE无法成功接收到网络设备发送的随机接入响应消息，从而导致UE无法成功接入网络设备。
发明内容
本公开实施例提供一种信号传输方法、设备及系统，以解决现有技术中网络设备在多个波束中向UE发送随机接入响应消息的情况下，UE无法成功接收到网络设备发送的随机接入响应消息，而无法成功接入网络设备的问题。

第五方面，本公开实施例提供了一种终端设备，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所述的信号传输方法的步骤。
第六方面，本公开实施例提供一种网络设备，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第二方面所述的信号传输方法的步骤。
第七方面，本公开实施例提供一种计算机可读存储介质，所述计算机可读存储介质上存储计算机程序，所述计算机程序被处理器执行时实现如上述信号传输方法的步骤。
在本公开实施例中，终端设备可以确定第一波束；并在第一波束对应第一资源集合的第一资源上，向网络设备发送第一上行信号，第一上行信号为数据信道上承载的上行信号。如此，网络设备可以接收到终端设备在第一波束上发送的第一上行信号，并从多个波束中选择出第一波束，以在第一波束(即第二波束)对应的第二资源上向终端设备发送第一下行信号；进而，使得终端设备可以从第一波束中成功接收到第一下行信号。从而，可以提高终端设备采用数据信道向网络设备发送上行信号之后，在多波束中成功接收下行信号的概率。

具体实施方式
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作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。
需要说明的是，本文中的“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种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。
需要说明的是，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能或作用基本相同的相同项或相似项进行 区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。例如，第一波束和第二波束是用于区别不同的波束，而不是用于描述波束的特定顺序。
需要说明的是，本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
需要说明的是，本申请实施例中，“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。本申请实施例中的“多个”的含义是指两个或两个以上。
需要说明的是，本申请实施提供的信号传输方法可以应用于RACH-less切换的场景中。
其中，RACH-less切换包括以下步骤：
步骤1：在终端设备(如UE)移动性过程中，终端设备可以根据网络设备配置的数据信道的发送资源信息，在目标小区发送上行信号。网络设备会指示终端设备在该目标小区发送的上行信号的最大时间提前量(time advanced，TA)值，如，TA值与源小区相同，或TA值为“0”。具体的，上述RACH-less切换可以为终端设备发起目标小区切换，或终端设备发起辅助小区组(Secondary Cell Group，SCG)切换(change)。
步骤2：终端设备在接收到网络设备发送的小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)调度的竞争解决标识(Contention Resolution ID)信息后，认为该移动性过程成功。例如，终端设备发起的目标小区切换成功，或终端设备发起的SCG change成功。
示例性的，网络设备可以为终端设备配置数据信道的发送资源信息，如物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的上行授权(Uplink Grant，UL grant)。例如，在终端设备移动性过程中向网络设备发起随机接入的情况下，终端设备可以将随机接入请求消息承载在PUSCH中发送给网络设备。网络设备接收到随机接入请求消息之后，可以向终端设备发送随机接入响应消息，以使得终端设备接入网络设备。
具体的，本申请实施提供的信号传输方法可以应用于终端设备与网络设备在多波束上传输信号的过程中，如终端设备在多个波束中从网络设备接收下行信号的过程中。
示例性的，在终端设备将随机接入请求消息承载在PUSCH中发送给网络设备之后，网络设备可以在多个波束中向终端设备发送随机接入响应消息，使得终端设备在该多个波束中从网络设备接收随机接入响应消息。
然而，现有技术仅在终端设备通过物理随机接入信道(Physical Random Access Channel，PRACH)发起的随机接入的过程中，支持终端设备选择PRACH资源对应的特定波束；并在网络设备在多波束中向终端设备发送随机接入响应消息的情况下，通过该特定波束对应的下行信道从网络设备接收该随机接入响应信息。而在终端设备通过PUSCH发起随机接入的过程中，终端设备不会选择在特定的波束上发送随机接入请求消息，从而后续终端设备并不能确定网络设备在多个波束中的哪个波束上发送随 机接入响应消息。如此，导致终端设备可能无法成功接收到网络设备发送的随机接入响应消息。
针对上述问题，本公开实施例提供一种信号传输方法、设备及系统，终端设备可以确定第一波束；并在第一波束对应第一资源集合的第一资源上，向网络设备发送第一上行信号，第一上行信号为数据信道上承载的上行信号。如此，网络设备可以接收到终端设备在第一波束上发送的第一上行信号，并从多个波束中选择出第一波束，以在第一波束(即第二波束)对应的第二资源上向终端设备发送第一下行信号；进而，使得终端设备可以从第一波束中成功接收到第一下行信号。从而，可以提高终端设备采用数据信道向网络设备发送上行信号之后，在多波束中成功接收下行信号的概率。
即，在终端设备通过PUSCH发起随机接入过程中，终端设备可以在第一波束对应的PUSCH资源上，向网络设备发送随机接入请求；使得网络设备可以从多个波束中选择第一波束，并在第一波束对应的下行资源上，向终端设备发送随机接入响应消息；进而，使得终端设备可以从多个波束中选择出第一波束，并在第一波束上成功接收到该随机接入响应消息。如此，可以解决现有技术中网络设备在多个波束中向终端设备发送随机接入响应消息的情况下，终端设备无法成功接收到网络设备发送的随机接入响应消息，而无法成功接入网络设备的问题。

本公开实施例提供的网络设备，网络设备可以为终端设备配置目标配置信息；其中，目标配置信息至少用于指示第一对应关系，第一对应关系用于指示第一波束与第一资源集合对应，第一资源集合中的第一资源上的第一上行信号为数据信道上承载的上行信号。如此，网络设备在第一波束对应的第一资源集合中的第一资源上，从用户设备终端设备接收第一上行信号之后，可以从多个波束中选择出第二波束(即第一波束)，以在第二波束对应的第二资源上向终端设备发送第一下行信号。进而，可以使得终端设备可以从第二波束中成功接收到第一下行信号。从而，可以提高终端设备采用数据信道向网络设备发送上行信号之后，在多波束中成功接收下行信号的概率。
本公开实施例中，在图8中，总线架构可以包括任意数量的互联的总线和桥，具体由处理器701代表的一个或多个处理器和存储器703代表的存储器的各种电路链接在一起。总线架构还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路链接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。 总线接口提供接口。收发机702可以是多个元件，即包括发送机和接收机，提供用于在传输介质上与各种其他装置通信的单元。针对不同的用户设备，用户接口704还可以是能够外接内接需要设备的接口，连接的设备包括但不限于小键盘、显示器、扬声器、麦克风、操纵杆等。处理器701负责管理总线架构和通常的处理，存储器703可以存储处理器701在执行操作时所使用的数据。
另外，网络设备700还包括一些未示出的功能模块，在此不再赘述。
可选的，本公开实施例还提供一种终端设备，包括处理器，存储器，存储在存储器上并可在处理器上运行的计算机程序，该计算机程序被处理器执行时实现上述实施例中的信号传输方法的过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
可选的，本公开实施例还提供一种网络设备，包括处理器，存储器，存储在存储器上并可在处理器上运行的计算机程序，该计算机程序被处理器执行时实现上述方法实施例中的信号传输方法的过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述实施例中的信号传输方法的多个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，上述的计算机可读存储介质包括只读存储器(Read-Only Memory，简称ROM)、随机存取存储器(Random Access Memory，简称RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本申请多个实施例所述的方法。
