本申请主张在2018年3月30日在中国提交的中国专利申请号No.201810276657.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种上行传输方法及终端。
背景技术
与以往的通信系统相比，未来第五代(5G)移动通信系统需要适应更加多样化的场景和业务需求。新空口(New radio，NR)的主要场景包括移动宽带增强(enhanced mobile broadband，eMBB)、大规模物联网(massive machine type of communication，mMTC)和超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)，这些场景对系统提出了高可靠、低时延、大带宽、广覆盖等要求。
在传统的上行传输模式下，终端如果需要发送上行数据，首先要发送调度请求(scheduling request，SR)。基站在收到终端发送的SR后，通过上行授权(UL grant)分配终端上行传输的资源，终端收到UL grant后根据调度信息进行那些上行数据的传输。这种方式在带宽不受限或连接数不多的时候，能够获得较好的系统性能。NR支持半静态调度(configured grant)方式，减少信令交互流程，从而能够降低终端的功耗。为了提高资源的利用率，多个终端可以在相同的资源上采用免授权的方式发送上行数据。
在正交传输方式下，不同终端的传输在时频域上是正交的，因此通过解调参考信号(Demodulation Reference Signal，DMRS)识别终端之后，基站不再需要区分终端。而在非正交传输方式下，基站不仅要识别终端，同时也要对上行接收信号进行多用户检测。这增加了基站的接收的复杂度和处理时延。同时，有限的终端识别信号与终端一一对应的方式难以满足需要支持大量终端接入的场景。
发明内容
本公开实施例提供一种上行传输方法及终端，以解决在非正交传输方式下，有限的终端识别信号与终端一一对应的方式，增加了基站的接收的复杂度和处理时延，难以满足需要支持大量终端接入的问题。

其中，一个DMRS配置信息对应一个多址标识、且不同的多址标识对应不同的DMRS配置信息。
第二方面，本公开实施例提供一种终端，包括：
获取模块，用于获取网络设备配置的至少一个解调参考信号DMRS配置信息和至少一个多址标识；
传输模块，用于在至少一个DMRS配置信息和所述至少一个多址标识中选择具有对应关系的目标DMRS配置信息和目标多址标识，进行上行传输；
其中，一个DMRS配置信息对应一个多址标识、且不同的多址标识对应不同的DMRS配置信息。

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公开一部分实施例，而不是全部的实施例。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，都属于本公开保护的范围。

下面结合附图介绍本公开的实施例。本公开实施例提供的侦听指示方法、终端及网络设备可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation，5G)移动通信技术的系统(以下均简称为5G系统)，所述领域技术人员可以了解，5G NR系统仅为示例，不为限制。
在进行本公开实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
为了能够区分不同终端的信号，终端在上行传输时可采用非正交技术对上行信号进行处理，具体来说，不同终端可采用不同的多址标识(Multiple Access signature)。其中，多址标识可以是以下的一种或多种：
码本(Codebook)/码字(Codeword)；
顺序(Sequence)；
Interleaver和/或映射模式(mapping pattern)；
解调参考信号(Demodulation reference signal)；
前导码(Preamble)；
空间范围(Spatial-dimension)；
功率范围(Power-dimension)。
基站在接收的时候，采用高级接收机(advanced receiver)进行多用户检测，根据终端所采用的多址标识区分终端的信号并解码。
终端在上行半静态调度的传输时，基站并不知道哪些终端何时会发送上行数据。因此基站需要对发送上行数据的终端进行识别。现有的方法是通过解调参考信号(DMRS)来作为终端识别的信号。在这种情况下，基站通过 检测DMRS，可以获知哪些终端在发送上行传输信号。
为了节省功耗和信令开销，多个终端可以在相同的资源上采用半静态调度的方式发送上行数据。基站在接收上行数据时，进行盲检并识别出进行上行传输的终端并进行多用户检测。本公开实施例给出了一种上行传输方法及终端。
具体地，如图1所示，本公开实施例提供一种上行传输方法，应用于终端，包括：
步骤101，获取网络设备配置的至少一个解调参考信号DMRS配置信息和至少一个多址标识；
需要说明的是，对于至少一个DMRS配置信息和至少一个多址标识，其中一个DMRS配置信息对应一个多址标识、且不同的多址标识对应不同的DMRS配置信息DMRS配置信息，即DMRS配置信息与多址标识为一一对应的关系，也就是说，一个DMRS配置信息只对应一个多址标识，一个多址标识也只对应一个DMRS配置信息，例如，网络设备为终端配置了两个DMRS配置信息以及两个多址标识，两个DMRS配置信息和两个多址标识之间为一一对应的关系。
步骤102，在至少一个DMRS配置信息和所述至少一个多址标识中选择具有对应关系的目标DMRS配置信息和目标多址标识，进行上行传输；
需要说明的是，终端在进行上行传输时，需要在网络设备为其配置的多个DMRS配置信息和多个多址标识中选择一对用于进行上行传输，具体地，终端在所述在至少一个DMRS配置信息和所述至少一个多址标识中选择具有对应关系的目标DMRS配置信息和目标多址标识之后，还需要根据所述目标DMRS配置信息和所述目标多址标识，确定数据加扰参数，以利用该数据加扰参数实现对数据发送的控制。
需要说明的是，至少一个DMRS配置信息和至少一个多址标识为网络设备为终端配置，该至少一个DMRS配置信息和至少一个多址标识可以是网络设备在配置完成后一同发送给终端，也可以是网络设备分时将至少一个DMRS配置信息和至少一个多址标识发送给终端。例如，在进行发送时，网络设备可以在第一时刻将至少一个DMRS配置信息发送给终端，在第二时刻 将至少一个多址标识发送给终端。因至少一个DMRS配置信息和至少一个多址标识之间存在映射关系，该二者的映射关系可以是协议约定，终端侧可以直接获知的，也可以是网络设备通知给终端的，网络设备可以将该映射关系与至少一个DMRS配置信息和至少一个多址标识一同发送给终端，也可以分时的进行发送。
具体地，网络设备可以采用广播方式或无线资源控制(RRC)信令(例如，专用RRC信令)方式进行上述信息的发送，具体地，终端也是通过广播方式或预设RRC信令获取至少一个DMRS配置信息和至少一个多址标识。
还需要说明的是，网络设备在进行DMRS配置信息和多址标识配置时，可以采用如下方式中的一种进行配置。
方式一、网络设备在进行至少一个DMRS配置信息和至少一个多址标识配置时，为不同终端配置的DMRS配置信息和多址标识是不同的。
例如，网络设备为UE1和UE2分别配置了不同的DMRS配置信息，且对应的多址标识也是不同的，如图2所示，UE1的DMRS配置信息分别为DMRS配置信息1、DMRS配置信息2、DMRS配置信息3和DMRS配置信息4，其对应地多址标识分别为：多址标识1、多址标识2、多址标识3和多址标识4；如图3所示，UE2的DMRS配置信息分别为DMRS配置信息5、DMRS配置信息6、DMRS配置信息7和DMRS配置信息8，其对应地多址标识分别为：多址标识5、多址标识6、多址标识7和多址标识9。
方式二、网络设备为不同的终端所配置的DMRS配置信息存在部分相同时，相同的DMRS配置信息在不同终端对应的多址标识相同。
例如，网络设备为UE1和UE2分别配置了至少一个DMRS配置信息和至少一个多址标识，其中，UE1和UE2的候选集中包含了部分相同的DMRS配置信息，且同一个DMRS配置信息对应的多址标识相同。如图2所示，UE1的DMRS参数分别为DMRS配置信息1、DMRS配置信息2、DMRS配置信息3和DMRS配置信息4，其对应地多址标识分别为：多址标识1、多址标识2、多址标识3和多址标识4；如图4所示，UE2的DMRS配置信息分别为DMRS配置信息1、DMRS配置信息2、DMRS配置信息5和DMRS配置信息6，其对应地多址标识分别为：多址标识1、多址标识2、多址标识5和 多址标识6。
方式三、网络设备为不同的终端所配置的DMRS配置信息存在部分相同时，相同的DMRS配置信息在不同终端对应的多址标识不相同。
例如，网络设备为UE1和UE2分别配置了至少一个DMRS配置信息和至少一个多址标识，其中，UE1和UE2的候选集中包含了部分相同的DMRS配置信息，且不同终端配置的相同的DMRS配置信息对应的多址标识也是不同的。如图2所示，UE1的DMRS配置信息分别为DMRS配置信息1、DMRS配置信息2、DMRS配置信息3和DMRS配置信息4，其对应地多址标识分别为：多址标识1、多址标识2、多址标识3和多址标识4；如图5所示，UE2的DMRS配置信息分别为DMRS配置信息1、DMRS配置信息2、DMRS配置信息5和DMRS配置信息6，其对应地多址标识分别为：多址标识5、多址标识6、多址标识7和多址标识8。
还需要说明的是，当采用循环前缀正交频分复用波形时，一个DMRS配置信息中包含至少一个DMRS序列生成的加扰参数，即同一个终端中，属于同一个DMRS配置信息中的加扰参数对应的都是相同的多址标识。
例如，UE1包含了多个DMRS配置信息，且每个DMRS配置信息中包含至少两个加扰参数，属于同一个DMRS配置信息中的加扰参数对应的都是相同的多址标识。例如，如图6所示，UE1包含DMRS配置信息1和DMRS配置信息2，其中，DMRS配置信息1包含加扰参数1，其对应地多址标识均为：多址标识1；DMRS配置信息2包含加扰参数2，其对应地多址标识为：多址标识2；如图7所示，UE1包含DMRS配置信息1和DMRS配置信息2，其中，DMRS配置信息1包含加扰参数1和加扰参数2，其对应地多址标识均为：多址标识1；DMRS配置信息2包含加扰参数1和加扰参数2，其对应地多址标识为：多址标识2。
进一步地，在确定目标DMRS配置信息和目标多址标识后，便可以利用该目标DMRS配置信息和目标多址标识进行上行传输，需要说明的是，在进行传输时，是将终端的标识信息(例如，终端的ID)与数据一起进行发送，具体地，在进行上行传输时，可以采用如下方式中的一种实现：
A1、通过媒体接入控制层控制单元(MAC CE)发送终端的标识信息；
需要说明的是，在此种情况下，网络设备需要成功解码数据后才能获取终端的标识信息。
A2、将终端的标识信息加扰在循环冗余校验码(CRC)中进行发送；
需要说明的是，在此种情况下，是把终端的标识信息加扰到数据的CRC校验比特上，该CRC校验比特是用于校验数据的，会随着数据一起发送。
A3、将终端的标识信息承载于数据信道中进行发送；
需要说明的是，在此种情况下，所述终端的标识信息承载于数据信道中预留的资源中，且所述终端的标识信息以独立编码的方式承载于所述数据信道中。终端标识信息承载于数据信道时的编码速率、beta偏移因子(beta offset)等信息可由网络设备配置。
A4、将终端的标识信息附着在传输块后进行发送。
需要说明的是，在此种情况下，所述终端的标识信息采用独立编码的方式附着在传输块后，或所述终端的标识信息采用联合编码的方式附着在传输块后。终端标识信息附着在传输块后采用单独编码时的编码速率等信息可由网络设备配置。
需要说明的是，本公开实施例通过在网络设备配置的至少一个DMRS配置信息和至少一个多址标识中，选择具有对应关系的目标DMRS配置信息和目标多址标识，进行上行传输，以此降低了基站的接收的复杂度和处理时延，可以支持大量终端的接入，提升了网络通信的性能。

获取模块801，用于获取网络设备配置的至少一个解调参考信号DMRS配置信息和至少一个多址标识；
传输模块802，用于在至少一个DMRS配置信息和所述至少一个多址标识中选择具有对应关系的目标DMRS配置信息和目标多址标识，进行上行传输；
其中，一个DMRS配置信息对应一个多址标识、且不同的多址标识对应不同的DMRS配置信息。
进一步地，所述获取模块801，用于：
获取所述网络设备通过广播方式或无线资源控制RRC信令方式，为终端 配置的所述至少一个DMRS配置信息和所述至少一个多址标识。
进一步地，在采用循环前缀正交频分复用波形时，一个DMRS配置信息中包含至少一个DMRS序列生成的加扰参数。

通过媒体接入控制层控制单元发送终端的标识信息；
将终端的标识信息加扰在循环冗余校验码中进行发送；
将终端的标识信息承载于数据信道中进行发送；
将终端的标识信息附着在传输块后进行发送。
具体地，在将终端的标识信息承载于数据信道中进行发送时，所述终端的标识信息承载于数据信道中预留的资源中，所述终端的标识信息以独立编码的方式承载于所述数据信道中。
具体地，在将终端的标识信息附着在传输块后进行发送时，所述终端的标识信息采用独立编码的方式附着在传输块后，或所述终端的标识信息采用联合编码的方式附着在传输块后。
需要说明的是，该终端实施例是与上述应用于终端侧的上行传输方法相对应的终端，上述实施例的所有实现方式均适用于该终端实施例中，也能达到与其相同的技术效果。

处理器911是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，通过运行或执行存储在存储器990内的软件程序和/或模块，以及调用存储在存储器990内的数据，执行终端的各种功能和处理数据，从而对终端进行整体监控。处理器911可包括一个或多个处理单元；可选的，处理器911可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器911中。
终端90还可以包括给各个部件供电的电源912(比如电池)，可选的，电源912可以通过电源管理系统与处理器911逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，终端90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，包括处理器911，存储器990，存储在存储器990上并可在所述处理器911上运行的计算机程序，该计算机程序被处理器911执行时实现应用于终端侧的上行传输方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
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应用于终端侧的上行传输方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(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。
其中，本公开实施例中所说的网络设备可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是LTE中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来8G网络中的基站等，在此并不限定。
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，本公开的技术方案本质上或者说对相关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(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
以上所述的是本公开的可选实施方式，应当指出对于本技术领域的普通人员来说，在不脱离本公开所述的原理前提下还可以作出若干改进和润饰，这些改进和润饰也在本公开的保护范围内。
