附图说明
通过阅读下文优选实施方式的详细描述，各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的，而并不认为是对本发明的限制。而且在整个附图中，用相同的参考符号表示相同的部件。在附图中：

图6为本发明实施例提供的通信设备的结构示意图。
具体实施方式
为了更好的理解本发明的实施例方式，下面先介绍以下技术点：
一、网络提供的参考时间：
在长期演进(Long Term Evolution，LTE)系统中，网络给UE发送系统消息(如，SIB16)，该系统消息中可以指示参考时间量(如，Treference)，包括：
(1)世界协调时间(Coordinated Universal Time，UTC)；
(2)阳光节约时或夏时制时间(Daylight Saving Time，DST)；
(3)全球定位系统(Global Positioning System，GPS)时间；
(4)本地时间。
当UE接收到该时间信息的时候，为了保证UE侧时间和网络侧时间理解一致，协议约定UE接收到的该参考时间对应的时间位置为：该系统消息的系统消息发送窗口的结束边界所在的系统帧号(System Frame Number，SFN)的边界。
例如，UE接收到参考时间信息的SIB16的位置为(SFN_2，Subframe_1)，该SIB16的系统消息发送窗口为10个子帧(subframe，1个SFN中有10个Subframe)，则UE收到参考时间信息的SIB16对应系统消息窗口的结束边界为(SFN_3，Subframe_1)，则UE收到的参考时间对应为SFN_3的结束边界时间。
网络提供的参考时间还可以通过单播方式发送给UE，在单播消息中会携带一个参考SFN值，协议约定UE接收到的该参考时间对应的时间位置为：距离接收该参考时间最近的SFN为参考SFN值的系统帧结束边界。
例如，UE接收到参考时间信息的位置为(SFN_2，subframe_1)，单播消息中携带的参考SFN值为SFN＝3，则UE收到的参考时间对应为未来第一个SFN＝3的系统帧结束边界。
二、双连接(Dual Connectivity，DC)：
在第五代移动通信技术(5th-Generation，5G)系统中采用了DC架构(包括主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG))，而该MCG对应于网络侧的主节点(Master Node，MN)，而该SCG对应于网络侧的辅节点(Secondary Node，SN)。MCG的主小区称为PCell，SCG的主小区称为主辅小区(Primary Secondary Cell，PScell)，统称为SpCell。MCG和SCG的辅小区都称为辅小区(Secondary cell，SCell)。信令无线承载(Signalling Radio Bearer，SRB)1为UE和MN之间的信令承载，SRB3为UE和SN之间的信令承载。
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“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。
本文所描述的技术不限于长期演进型(Long Time Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division  Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。
术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。
下面结合附图介绍本发明的实施例。本发明实施例提供的一种上行传输的方法、上行传输指示的方法和设备可以应用于无线通信系统中。参考图1，为本发明实施例提供的一种无线通信系统的架构示意图。如图1所示，该无线通信系统可以包括：第一网络设备11、第二网络设备12和终端13，第一网络设备11可以成为第一网络节点、第二网络设备12可以成为第二网络节点，终端13可以记做UE13，第一网络设备11可以与第二网络设备12和终端13通信(传输信令或传输数据)。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
本发明实施例提供的第一网络设备11和第二网络设备12可以为基站， 该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络设备(例如，下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))等设备。
本发明实施例提供的终端13可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
参见图2，本发明实施例中一种获取参考时间信息的方法，该方法的执行主体为终端，该方法的具体步骤如下：
步骤201：从第一小区接收第一信息，所述第一信息用于辅助所述终端获取(或发现)第二小区提供的参考时间信息；
在本发明实施例中，第一小区可以为终端的驻留小区，该第一小区为独立工作的小区，即SA cell。
步骤202：根据所述第一信息，获取第二小区提供的参考时间信息，所述第二小区为所述第一小区的邻小区；
在本发明实施例中，终端可以为非连接态终端(例如，空闲态终端)，或者也可以为连接态终端。
在本发明实施例中，第二小区可以为第一小区的邻小区，当然也并不限于此。
示例性地，第一信息也可以称为辅助信息，SA cell向终端提供其邻小区相关的辅助信息，该辅助信息用于辅助终端发现邻小区提供的参考时间信息，这样终端可以根据第一信息，获取第二小区提供的参考时间信息。
在一些实施方式中，终端根据第一信息，通过时分双工(Time Division Duplexing，TDD)方式，接收第二小区提供的参考时间信息。
进一步地，上述时分双工方式由终端确定，或者由协议约定，或者由网络侧配置。
在一些实施方式中，如终端为非连接态，该终端根据第一信息，通过频分双工(Frequency Division Duplexing，FDD)方式，接收第二小区提供的参 考时间信息。
进一步地，第二小区的对应的频点与终端的服务小区频点属于终端支持的频带组合(band combination)。
在一些实施方式中，第一信息可以包括以下一项或多项：
(1)第一指示信息，该第一指示信息指示第二小区为独立工作的小区或者指示第二小区为非独立工作的小区(Non standalone cell，NSA cell)，例如：通过1比特指示第二小区是否是NAS cell，比如取值为“0”，表示第二小区是NSA cell，取值为“1”，表示第二小区不是NSA cell；
(2)第二小区的频点信息，例如第二小区的频点为f1；
(3)第二小区的小区标识信息，例如：物理小区标识(Physical Cell Identifier，PCI)、全球小区标识(Global Cell Identifier，GCI)、小区标识(Cell ID)；
(4)第二小区的参考时间精度信息，例如：第二小区体用的参考时间精度为10纳秒(ns)；
(5)第二小区的参考时间误差信息，例如：第二小区提供的参考时间的时间误差为100ns；
(6)第二小区的参考时间类型信息，例如：第二小区提供的参考时间类型为GPS时间、UTC时间或本地时间；
可选地，第一信息中可以包括：第一指示信息，且第一指示信息指示第二小区是SA cell，图2所示的方法还可以包括：将第二小区对应的频点设置为小区选择或重选的高优先级频点。
可选地，第一信息中可以包括：第一指示信息，且第一指示信息指示第二小区是NSA cell，图2所示的方法还可以包括：将第二小区对应的频点设置为小区选择或重选的低优先级频点；或者，将第二小区对应的频点设置为小区选择或重选禁止接入的频点。
进一步地，当将第二小区对应的频点设置为小区选择或重选禁止接入的频点时，本方法还包括：确定小区选择或重选禁止接入的时长。
再进一步地，上述小区选择或重选禁止接入的时长可以由协议约定，或者由网络侧配置。
在一些实施方式中，图2所示的方法还可以包括：将第二小区的邻频点设置为小区选择或重选的高优先级频点，第二小区的邻频点和第二小区的频点组成的频带组合为终端支持的频带组合。
在现有技术中，5G网络中存在NSA cell，该类小区不广播SIB1系统消息，由于其他SIB的调度信息在SIB1中，因而UE不能直接通过该非独立工作的小区获取其他SIB(如SIB2、SIB3、SIB4等)的信息。对于连接态UE来说，UE只会读取该类小区的主系统信息块(Master Information Block，MIB)，而该类小区的其他SIB信息是通过主控小区(如UE的主小区(Primary Cell，PCell))的无线资源控制(Radio Resource Control，RRC)信令告知给UE的。而对于非连接态UE来说，由于其不处于RRC连接态，因而其并没有所属的主控小区，进而是无法获取NSA cell的其他SIB的调度信息以及其他SIB所承载的信息的。
在一些实施方式中，终端通过第二小区的第一系统消息，读取第二小区提供的参考时间信息，进一步地，第一系统消息为第二小区提供的用于承载参考时间信息的系统消息。可选地，第一系统消息可以为系统信息块(System Information Block，SIB)9，当然并不限于此。
例如，第二小区可以为非独立工作的小区，通过对第二小区的系统消息进行增强，使得非独立工作的第二小区的系统消息可以承载该第二小区提供的参考时间信息，这样终端可以直接通过该非独立工作的第二小区获取参考时间信息。
可选地，第二小区为非独立工作的小区，图2所示的方法还可以包括：终端从第二小区接收第二指示信息，该第二指示信息用于禁止无需获取第二小区的参考时间信息的终端接入。示例性的，非独立工作的小区的主系统消息(MIB)中携带所述第二指示信息，对于无需获取参考时间的UE，认为该小区是不可以驻留的，进而不会尝试读取该小区的其他系统消息(如SIB1)。而对于需要从该小区获取参考时间的UE，会尝试读取该小区的其他系统消息(如SIB9)以获取参考时间消息。
例如，第二小区可以为非独立工作的小区，对于非连接态UE，该UE可以基于第一信息找到提供参考时间信息的小区，读取该小区的系统信息以获 取参考时间，避免现有技术中非连接态终端无法获取非独立工作的小区的参考时间信息的问题。
又例如，对于连接态UE，如SCG的小区提供参考时间，该UE可以基于第一信息可以知道某SCG的小区可以提供参考时间，进而主动去读取SCG的小区的系统信息以获取参考时间，避免现有技术中连接态终端无法获取非独立工作的小区的参考时间信息的问题。
在一些实施方式中，通过终端与第一网络节点之间的专用信令，从第一网络节点接收第二小区提供的参考时间信息，例如，SCG的小区可以提供参考时间，并且UE建立了SRB3，则SN通过SRB3直接向UE提供参考时间信息。
在一些实施方式中，通过终端与第一网络节点之间的专用信令，接收第二网络节点下的第二小区提供的参考时间信息；例如，SCG的小区可以提供参考时间，但UE没有与SN建立SRB3承载，则MN通过SRB1或SRB2提供SCG的小区提供的参考时间信息。
进一步地，终端从第一网络节点接收第三指示信息，该第三指示信息指示参考时间信息由第二网络节点生成；终端根据第三指示信息，将第二网络节点的特定小区确定为参考时间的参考小区，该特定小区由协议约定或网络侧配置。
在一些实施方式中，终端根据第一信息，从多个第二小区中确定一个特定小区或频点；终端从该特定小区或频点获取该特定小区或频点提供的参考时间信息。
示例性地，第一信息用于发现邻小区A和邻小区B提供的参考时间信息，例如：邻小区A提供的参考时间信息为10ns，邻小区B提供的参考时间信息为100ns，则终端可以根据第一信息，以及终端的需求，选择从小区A读取该小区A提供的参考时间信息为10ns。
进一步地，上述特定小区或频点满足以下一项或多项条件：
(1)特定小区或频点提供的参考时间精度高于或等于终端的时间精度需求；
(2)特定小区或频点提供的参考时间误差小于或等于终端的同步精度误 差需求；
(3)特定小区或频点提供的参考时间类型是终端所需要的参考时间类型。
在本发明实施例中，独立工作的第一小区向终端发送第一信息，该第一信息可以辅助终端发现第二小区提供的参考时间信息，这样终端可以根据第二小区提供的参考时间信息对终端侧的时间进行调整。
参见图3，本发明实施例提供一种指示参考时间信息的方法，该方法的执行主体为第一网络节点，第一网络节点服务于第一小区，该方法的具体步骤如下：
步骤301：向终端发送第一信息；
在本发明实施例中，终端可以为非连接态终端(例如，空闲态终端)，或者也可以为连接态终端。
在本发明实施例中，第一小区为独立工作的小区，即SA cell；第一信息也可以称为辅助信息，该第一信息用于辅助终端获取第二小区提供的参考时间信息；第二小区为第一小区的邻小区。
例如，对于非连接态UE，该UE可以基于第一信息找到提供参考时间信息的小区，读取该小区的系统信息以获取参考时间。对于连接态UE，如SCG的小区提供参考时间，该UE可以基于第一信息知道某SCG的小区提供参考时间，进而主动去读取SCG的小区的系统信息以获取参考时间。
在一些实施例中，图3所示方法还可以包括：第一网络节点向终端发送第二网络节点的第二小区提供的参考时间信息。
进一步地，向终端发送第三指示信息，所述第三指示信息指示所述参考时间信息由所述第二网络节点生成。其中，第二网络节点服务第二小区。
在一些实施方式中，第一信息可以包括以下一项或多项：
(1)第一指示信息，该第一指示信息指示第二小区为独立工作的小区或者指示第二小区为非独立工作的小区，例如：通过1比特指示第二小区是否是NAS cell，比如取值为“0”，表示第二小区是NSA cell，取值为“1”，表示第二小区不是NSA cell；
(2)第二小区的频点信息，例如：第二小区的频点为f1；
(3)第二小区的小区标识信息，例如：PCI、GCI、Cell ID；
(4)第二小区的参考时间精度信息，例如：第二小区提供的参考时间精度为10ns；
(5)第二小区的参考时间误差信息，例如：第二小区提供的参考时间的时间误差为100ns；
(6)第二小区的参考时间类型信息，例如：第二小区提供的参考时间类型为GPS时间、UTC时间或本地时间；
在本发明实施例中，独立工作的第一小区可以向终端发送第一信息，该第一信息可以辅助终端发现第二小区提供的参考时间信息，这样终端可以根据第二小区提供的参考时间信息对终端侧的时间进行调整。
下面结合具体实施例对本发明的方法进行描述，本发明实施例的方法包括如下步骤：
步骤1：独立工作小区提供其邻小区相关的辅助信息，该辅助信息用于UE发现邻小区提供的参考时间信息。
例如：UE驻留在小区1上，小区1提供小区2相关的辅助信息，通过该辅助信息UE可以获取到小区2提供的参考时间信息。
其中，辅助信息为以下一项或多项的组合：
(1)邻小区是否是非独立工作的指示信息，例如：1比特指示邻小区是否是NAS cell，比如取值为“0”，表示邻小区是NSA cell，取值为“1”，表示邻小区不是NSA cell；
(2)邻小区的频点信息，例如：邻小区所在频点为f1；
(3)邻小区的小区标识信息，例如：PCI、GCI或Cell ID；
(4)邻小区的参考时间精度信息，例如：小区提供的参考时间精度为10ns；
(5)邻小区的参考时间误差信息，例如：小区提供的参考时间的时间误差为100ns；
(6)邻小区的参考时间类型信息，例如：小区提供的参考时间类型为GPS时间,UTC时间或本地时间等；
其中，辅助消息可以通过独立工作小区的系统消息提供给UE。
例如：小区1为SA cell，小区2可以提供参考时间，小区1在其系统消息(如新引入的SIBx)中提供小区2的参考时间相关辅助信息)；对于连接态 UE，所述的辅助信息还可以通过专用消息提供，例如连接态UE的主控小区(Primary cell，PCell)通过专用消息提供邻小区的参考时间相关辅助信息。
步骤2：UE根据辅助信息从特定小区或频点获取该小区或频点提供的参考定时信息。
进一步地，特定小区或频点满足以下一项或多项条件：
(1)特定小区或频点提供的参考时间精度高于或等于UE的时间精度需求；
(2)特定小区或频点提供的参考时间误差小于或等于UE的同步精度误差需求；
(3)特定小区或频点提供的参考时间类型是UE所需要的参考时间类型；
其中，UE从特定的小区或频点获取参考时间信息的方式为：
方式一：UE通过读取特定小区或频点下的小区的特定系统消息获取参考时间信息，该特定系统消息为小区提供的用于承载参考时间信息的系统消息(例如SIB9)。
进一步地，若提供通过系统消息提供参考时间信息的小区为非独立工作小区，该小区还携带指示信息，该指示信息用于禁止无需获取参考时间信息的UE接入。
例如：对于非连接态UE，UE基于辅助信息找到提供参考时间信息的小区，读取小区的系统信息以获取参考时间；对于连接态UE，如SCG的小区提供参考时间，UE基于辅助信息读取SCG的小区的系统信息以获取参考时间。
方式二：连接态UE通过与网络节点间的专用消息接收该网络节点下小区提供的参考时间信息；
例如：SCG的小区可以提供参考时间，并且UE建立了SRB3，则SN通过SRB3直接向UE提供参考时间信息；
方式三：连接态UE通过与网络节点间的专用消息接收其他网络节点的小区提供的参考时间信息；
例如：SCG的小区可以提供参考时间，但UE没有建立SRB3承载，则MN通过SRB1或SRB2提供SCG的小区提供的参考时间信息。
进一步地，下发参考时间信息的网络节点显示或隐式的指示是哪个网络节点生成的参考时间消息。UE接收到参考时间消息后，将指示的网络节点下的特定小区作为参考时间的参考小区。
例如：网络节点1给UE发送参考时间消息，显示或隐式指示UE该参考时间消息为网络节点2生成，则UE选择网络节点2下的小区(如PScell)作为参考时间消息中的参考时间的参考小区，其中所示的显示指示可以通过增加新的指示信息实现，所示的隐式指示方法可以通过将参考时间消息放在特定的容器(container)中实现；
进一步地，在网络节点向UE提供其他网络节点下小区提供的参考时间之前，网络节点需进行协商，协商内容举例如下：
对网络节点之间的同步误差进行协商，如网络节点2生成参考时间，网络节点1基于网络节点之间的同步误差调整网络节点2生成的参考时间。网络节点1给UE发送参考时间，则UE选择网络节点1下的小区(如PCell)作为参考时间消息中参考时间的参考小区。
其中，对于非连接态UE，为获取特定小区或频点上的参考时间，UE行为包括还以下一项或多项：
(1)UE以时分方式从某特定小区或频点下的小区接收参考时间信息，其中时分方式由UE自主设置或网络设置；
例如：UE驻留在小区1上，小区2提供UE所需的参考时间，UE周期性的从读取小区2的系统信息以接收参考时间信息，该周期可以是UE自己设置的，也可以是网络配置的；
(2)UE将某提供参考时间的小区的邻频点设置为小区选择或重新的高优先级频点，其中某提供参考时间的小区对应的频点与所述邻频点属于频带组合(band combination)，并且该频带组合是UE能够支持的频带组合；
进一步地，如果独立工作小区提供了某特定小区或频点下的小区是否是非独立工作小区的指示信息时，UE在执行小区选择或重选时还可以由如下行为：
(1)若独立工作小区提供了某特定小区或频点下的小区是独立工作小区的指示信息，则UE将该特定小区对应的频点或该频点设置为小区选择或重 新的高优先级频点；
例如：非连接态UE驻留在小区1上，小区1指示小区2提供参考时间信息并指示该小区2为独立工作小区，则UE将小区2对应的频点设置为小区选择或重选的高优先级频点；
(2)若独立工作小区提供了某特定小区或频点下的小区是非独立工作小区，则UE将该特定小区对应的频点或该特定频段设置为小区选择或重选低优先级频点，或将该特定小区对应的频段或该特定频段设置为小区选择或重新禁止接入频点。额外的，UE设置该频点禁止接入的时长，所述时长由协议约定或网络设置；
例如：非连接态UE驻留在小区1上，小区1指示小区2提供参考时间信息并指示该小区2为非独立工作小区，则UE将小区2对应的频点设置为小区选择/重新低优先级频点，或将该小区2对应的频点设置为小区选择。
