Description

上行控制信令的传输方法、设备及系统 技术领域
本发明涉及通信技术领域，尤其涉及一种上行控制信令的传输方法、设备及系统。
背景技术
5G New Radio(5G NR)是在3GPP组织中新近提出的一个课题，位于release 14中。随着新一代5G技术进入讨论阶段，一方面，由于通信系统是后项兼容的，所以后来研发的新技术倾向于兼容之前已经标准化的技术；而另一方面，由于4G LTE已经存在了大量的现有设计，如果为了达到兼容，必然要牺牲掉5G的很多灵活度，从而降低性能。所以，目前在3GPP组织中两个方向并行研究，不考虑后向兼容的技术讨论组，被称为5G NR。
如图1所示，在5G NR的讨论过程中，长时间上行控制信令在时隙中传输的结构有以下3种可能性，在图1(a)中，长时间上行控制信令占用时隙的所有时域符号，此时隙中符号数可以为7或14；在图1(b)中，长时间上行控制信令位于时隙GP之后，占用绝大多数时域符号；在图1(c)中，长时间上行控制信令位于GP和短时间上行控制信令之间。目前，在5G NR中，长时间上行控制信令所占用的时域符号数最低为4，总数不确定。
发明内容
本发明实施例提供一种上行控制信令的传输方法、设备及系统，以期提出一种通过多个时隙的不同频域资源跳频传输任意长度的上行控制信令的方法，有利于提高通信系统的分集增益。
第一方面，本发明实施例提供一种上行控制信令的传输方法，包括：
终端在多个时隙上传输上行控制信令，第一时隙中的第一符号组在第一频域资源上传输，第一时隙中的第二符号组在第二频域资源上传输；第二时隙中的第三符号组在第三频域资源上传输，第二时隙中的第四符号组在第四频域资源上传输，可见，终端能够通过多个时隙的不同频域资源跳频传输任意长度的上行控制信令，有利于提高通信系统的分集增益。
由上可见，本发明实施例中，终端传输的上行控制信令在第一时隙中的第一符号组在第一频域资源上传输，在第一时隙中的第二符号组在第二频域资源上传输，在第二时隙中的第三符号组在第三频域资源上传输，在第二时隙中的第四符号组在第四频域资源上传输，可见，终端能够通过多个时隙的不同频域资源跳频传输任意长度的上行控制信令，有利于提高通信系统的分集增益。
在一个可能的设计中，所述第一符号组的符号数大于所述第二符号组的符号数，且所述第一频域资源高于所述第二频域资源；所述第三符号组的符号数小于所述第四符号组的符号数，且所述第三频域资源高于所述第四频域资源。
由上可见，本设计中，由于第一符号组的符号数大于第二符号组的符号数，第三符号 组的符号数小于第四符号组的符号数，且第一频域资源高于第二频域资源，第三频域资源高于第四频域资源，如此，第一、第三频域资源上的符号数与第二、第四频域资源上的符号数相对接近，即差值较小，从而有利于更大化提高通信系统的分集增益。
在一个可能的设计中，所述第一符号组的最前一个符号早于所述第二符号组的最后一个符号；或，所述第二符号组的最前一个符号早于所述第一符号组的最后一个符号；或，
所述第三符号组的最前一个符号早于所述第四符号组的最后一个符号；或，所述第四符号组的最前一个符号早于所述第三符号组的最后一个符号。
在一个可能的设计中，所述第一符号组中的符号数等于所述第二符号组的符号数，且所述第三符号组中的符号数等于所述第四符号组的符号数。
由上可见，本设计中，由于第一符号组中的符号数等于第二符号组的符号数，且第三符号组中的符号数等于第四符号组的符号数，这使得第一、第三频域资源上的符号数与第二、第四频域资源上的符号数相同，从而有利于最大化提高通信系统的分集增益。
在一个可能的设计中，所述第一频域资源高于所述第二频域资源，所述第三频域资源高于所述第四频域资源。
在一个可能的设计中，所述第一符号组的最前一个符号早于所述第二符号组的最后一个符号，且，所述第四符号组的最前一个符号早于所述第三符号组的最后一个符号；或，
所述第二符号组的最前一个符号早于所述第一符号组的最后一个符号，且，所述第三符号组的最前一个符号早于所述第四符号组的最后一个符号。
在一个可能的设计中，所述多个时隙的每个时隙中用于传输所述上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS。
由上可见，本设计中，由于多个时隙的每个时隙中用于传输所述上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS，如此能够避免上行控制信令在传输过程中，时隙末尾的一个或两个符号容易受到邻小区的干扰的问题，有利于提高上行控制信令传输的抗干扰性。
在一个可能的设计中，所述上行控制信令为原始上行控制信令乘以预设码域序列的结果，所述多个时隙的每个时隙对应所述预设码域序列的一个元素，所述预设码域序列包含多个元素。其中，所述原始上行控制信令可以是所述多个时隙中的第一个时隙传输的信号。
由上可见，本设计中，由于预设码域序列包含多个元素，且每个时隙对应预设码域序列中的一个元素，即不同终端的上行控制信令可以通过乘以该预设码域序列中的不同元素以实现复用相同的时隙，从而实现通信系统的上行控制信令的信道容量的扩容。
在一个可能的设计中，所述上行控制信令由多个小区中的每个小区采用连续多个频域资源块PRB进行传输，且所述每个小区使用不同的频域扩频序列以避免小区相互干扰。
可见，本设计中，通信系统的每个小区能够通过使用多个连续的PRB传输上行控制信令，从而降低不同小区的长时间上行控制信令的互相干扰。
第二方面，本发明实施例提供一种上行控制信令的传输方法，包括：
终端在多个时隙上传输上行控制信令，所述多个时隙的每个时隙上的多个频域资源用 于传输上行控制信令；
所述每个时隙中用于传输所述上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS。
由上可见，本发明实施例中，终端在多个时隙上传输上行控制信令，其中，多个时隙的每个时隙上的多个频域资源用于传输上行控制信令，且每个时隙中用于传输上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS，如此能够避免上行控制信令在传输过程中，时隙末尾的一个或两个符号容易受到邻小区的干扰的问题，有利于提高上行控制信令传输的抗干扰性。
第三方面，本发明实施例提供一种上行控制信令的传输方法，包括：
网络侧设备在多个时隙上接收上行控制信令，第一时隙中的第一符号组在第一频域资源上传输，第一时隙中的第二符号组在第二频域资源上传输；第二时隙中的第三符号组在第三频域资源上传输，第二时隙中的第四符号组在第四频域资源上传输。
由上可见，本发明实施例中，网络侧设备接收的上行控制信令在第一时隙中的第一符号组在第一频域资源上传输，在第一时隙中的第二符号组在第二频域资源上传输，在第二时隙中的第三符号组在第三频域资源上传输，在第二时隙中的第四符号组在第四频域资源上传输，可见，网络侧设备能够通过多个时隙的不同频域资源跳频传输任意长度的上行控制信令，有利于提高通信系统的分集增益。
在一个可能的设计中，所述第一符号组的符号数大于所述第二符号组的符号数，且所述第一频域资源高于所述第二频域资源；所述第三符号组的符号数小于所述第四符号组的符号数，且所述第三频域资源高于所述第四频域资源。
在一个可能的设计中，所述第一符号组的最前一个符号早于所述第二符号组的最后一个符号；或，所述第二符号组的最前一个符号早于所述第一符号组的最后一个符号；或，
所述第三符号组的最前一个符号早于所述第四符号组的最后一个符号；或，所述第四符号组的最前一个符号早于所述第三符号组的最后一个符号。

具体实施方式
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描述。
请参阅图2，图2是本发明实施例提供的一种示例无线通信系统的系统架构图，该示例无线通信系统例如可以是无线蜂窝网络，该无线蜂窝网络可以包括全球移动通信系统(Global System for Mobile Communication，GSM)、通用移动通信系统(Universal Mobile Telecommunications System，UMTS)、长期演进(Long Term Evolution，LTE)、长期演进的演进(LTE-Advanced，LTE-A)等主流系统以及混合组成的异构系统，该示例无线通信系统具体包括终端、至少一个网络设备，至少一个网络设备中的网络设备可以是为用户提供接入和数据服务的基站，基站具体可以是LTE系统的演进型基站(EvolvedNodeB，eNB)，UMTS的网络设备(NodeB，NB)等，该至少一个网络设备可以用于提供第一小区和第二小区，该第一小区和第二小区所描述的小区概念可以包括城市小区Metro cell、微小区Micro cell、微微小区Pico cell、毫微微小区Femto cell等，且第一小区对应第一网络设备，第二小区对应第二网络设备，该第一网络设备和第二网络设备可以为同一个网络设备，也可以为不同的网络设备。
本发明实施例中，名词“网络”和“系统”经常交替使用，但本领域技术人员可以理解其含义。本发明实施例所涉及到的终端可以包括各种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
目前，如图3所示，LTE系统的上行控制传输方式中，1ms子帧在时域上分为两段各0.5ms传输，所传输的位置位于整个频带的两侧，以提高分集增益的效果。具体来讲，1ms包含14个符号，前7个符号在频带的一侧进行传输，后7个符号在频带的另一侧进行传输。比较图1和图2可发现以下区别：在图1中，整个子帧只有末尾的第三部分传输上行控制信令，仅仅占整个子帧的一小部分，可能只有一个符号的时长，而图2的现有技术一种，整个子帧在时域上都用来传输上行控制信令，时域上占有整个1ms子帧。新的系统中，没有足够的时域符号来应用现有技术一传输上行控制信令。
如图4所示，LTE中系统的多模式上行控制传输中，上行控制模式的类别包含1/1a/1b或者2/2a/2b等几种类型。当不同类别的模式传输时，1/1a/1b类别的上行控制信令可以在同一个频域资源上传输，而另一个类别的2/2a/2b上行控制信令不能与1/1a/1b在同一个频域传输，即不同类别的上行控制信令采用频分复用的方式分配给不同的用户UE使用；这里，每次调度会占用1ms的时长，在1ms中的前7个符号上位于一个RB上传输，在后7个符号上位于另外一个RB上传输。
如上分析可见，现有技术需要占据整个子帧传输上行控制信令，而5G NR的子帧设计中，需要支持不定符号长度的长时间上行控制信令。
有鉴于此，本发明实施例提供一种上行控制信令的传输方法、设备及系统，下面对本发明实施例进行详细说明。
结合附图5，对本发明实施例提供的上行控制信令的传输方法进行说明。图5示出了 本发明实施例提供的一种上行控制信令的传输方法，本方法适用于图2所示的示例无线通信系统。该方法包括：501～505部分，具体如下：
在501部分，终端在多个时隙上向网络侧设备发送(传输)上行控制信令，第一时隙中的第一符号组在第一频域资源上传输，第一时隙中的第二符号组在第二频域资源上传输；第二时隙中的第三符号组在第三频域资源上传输，第二时隙中的第四符号组在第四频域资源上传输。
其中，所述多个时隙至少包括所述第一时隙和所述第二时隙。所述上行控制信令至少由所述第一符号组、所述第二符号组、所述第三符号组以及所述第四符号组传输。
在502部分，网络侧设备在多个时隙上接收所述上行控制信令，第一时隙中的第一符号组在第一频域资源上传输，第一时隙中的第二符号组在第二频域资源上传输；第二时隙中的第三符号组在第三频域资源上传输，第二时隙中的第四符号组在第四频域资源上传输。
可以看出，本发明实施例中，通信系统中传输的上行控制信令在第一时隙中的第一符号组在第一频域资源上传输，在第一时隙中的第二符号组在第二频域资源上传输，在第二时隙中的第三符号组在第三频域资源上传输，在第二时隙中的第四符号组在第四频域资源上传输，可见，通信系统能够通过多个时隙的不同频域资源跳频传输任意长度的上行控制信令，有利于提高通信系统的分集增益。
在一个可能的示例中，所述第一符号组的符号数大于所述第二符号组的符号数，且所述第一频域资源高于所述第二频域资源；所述第三符号组的符号数小于所述第四符号组的符号数，且所述第三频域资源高于所述第四频域资源。
由上可见，本设计中，由于第一符号组的符号数大于第二符号组的符号数，第三符号组的符号数小于第四符号组的符号数，且第一频域资源高于第二频域资源，第三频域资源高于第四频域资源，如此，第一、第三频域资源上的符号数与第二、第四频域资源上的符号数相对接近，即差值较小，从而有利于更大化提高通信系统的分集增益。
在一个可能的示例中，所述第一符号组的最前一个符号早于所述第二符号组的最后一个符号；或，所述第二符号组的最前一个符号早于所述第一符号组的最后一个符号；或，
所述第三符号组的最前一个符号早于所述第四符号组的最后一个符号；或，所述第四符号组的最前一个符号早于所述第三符号组的最后一个符号。
在一个可能的示例中，所述第一符号组中的符号数等于所述第二符号组的符号数，且所述第三符号组中的符号数等于所述第四符号组的符号数。
由上可见，本设计中，由于第一符号组中的符号数等于第二符号组的符号数，且第三符号组中的符号数等于第四符号组的符号数，这使得第一、第三频域资源上的符号数与第二、第四频域资源上的符号数相同，从而有利于最大化提高通信系统的分集增益。
在一个可能的示例中，所述第一频域资源高于所述第二频域资源，所述第三频域资源高于所述第四频域资源。
在一个可能的示例中，所述第一符号组的最前一个符号早于所述第二符号组的最后一个符号，且，所述第四符号组的最前一个符号早于所述第三符号组的最后一个符号；或，
所述第二符号组的最前一个符号早于所述第一符号组的最后一个符号，且，所述第三 符号组的最前一个符号早于所述第四符号组的最后一个符号。
在一个可能的示例中，所述多个时隙的每个时隙中用于传输所述上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS。
其中，所述上行控制信令包括DMRS和上行控制信息UCI。
举例来说，如图6所示，第一、第三频域资源为PRB X，第二、第四频域资源为PRB Y，第一时隙和第二时隙分别为Slot1、Slot2，第一符号组的最前一个符号早于第二符号组的最后一个符号，且第四符号组的最前一个符号早于第三符号组的最后一个符号，图6所示的上行控制信令的传输方式为交换拓展传输方式，可选示例中，DMRS可以分别在第二符号组、第三符号组的最后一个符号传输，还可以在第i时隙的用于传输所述上行控制信令的最后一个符号进行传输，i为大于或等于3的。
由上可见，本设计中，由于多个时隙的每个时隙中用于传输所述上行控制信令的符号中的最后一个符号用于传输解调参考信号DMRS，如此能够避免上行控制信令在传输过程中，时隙末尾的一个或两个符号容易受到邻小区的干扰的问题，有利于提高上行控制信令传输的抗干扰性。
在一个可能的示例中，第一、第二、第三和第四符号组中，每个符号组中的第1个符号用于传输解调参考信号DMRS，所述每个符号组中除所述第1个符号之外的符号用于传输上行控制信息UCI。
举例来说，如图7所示，第一、第三频域资源为PRB X，第二、第四频域资源为PRB Y，第一时隙和第二时隙分别为Slot1、Slot2，第一符号组的最前一个符号早于第二符号组的最后一个符号，且第三符号组的最前一个符号早于第四符号组的最后一个符号，图7所示的上行控制信令的传输方式为非交换拓展传输方式，可选示例中，DMRS可以分别在第一符号组、第二符号组、第三符号组、第四符号组的第一个符号传输，还可以在第i时隙的第2i符号组、第2i-1符号组的第一个符号进行传输，i为大于或等于3的整数。
又举例来说，如图8所示，第一、第三频域资源为PRB X，第二、第四频域资源为PRB Y，第一时隙和第二时隙分别为Slot1、Slot2，第一符号组的最前一个符号早于第二符号组的最后一个符号，且第四符号组的最前一个符号早于第三符号组的最后一个符号，图8所示的上行控制信令的传输方式为交换拓展传输方式，可选示例中，DMRS可以分别在第一符号组、第二符号组、第三符号组、第四符号组的第一个符号传输，还可以在第i时隙的第2i符号组、第2i-1符号组的第一个符号进行传输，i为大于或等于3的整数。
在一个可能的示例中，所述上行控制信令为原始上行控制信令乘以预设码域序列的结果，所述多个时隙的每个时隙对应所述预设码域序列的一个元素，所述预设码域序列包含多个元素。其中，所述原始上行控制信令可以是所述多个时隙中的第一个时隙传输的信号。
举例来说，如图9所示，假设预设码域序列包含元素{+1，+1}和{+1，-1}，对于跨两个时隙的上行控制信令，每个时隙上在PRB X上均有一个DMRS符号，至少一个UCI符号，每个时隙上在PRB Y上均有一个DMRS符号，至少一个UCI符号。在各时隙上，各终端传输的DMRS或UCI信号分别乘以正交码{+1，+1}或{+1，-1}，以支持更多的终端进行接入。具体来讲，第一组终端的上行控制信令在传输时，在第一个时隙上传输的DMRS或UCI符号 上乘以+1，在第二个时隙上传输的DMRS或UCI符号上乘以+1，即第一组终端在第二个时隙上传输的信号和第一个时隙上传输的信号(DMRS信号或UCI信号)相同，第二组终端的上行控制信令在传输时，在第一个时隙上传输的DMRS或UCI符号上乘以+1，在第二个时隙上传输的DMRS或UCI符号上乘以-1，即第二组终端在第二个时隙上传输的信号是第一个时隙上传输的DMRS信号或UCI信号乘以-1的结果。
由上可见，本设计中，由于预设码域序列包含多个元素，且每个时隙对应预设码域序列中的一个元素，即不同终端的上行控制信令可以通过乘以该预设码域序列中的不同元素以实现复用相同的时隙，从而实现通信系统的上行控制信令的信道容量的扩容。
在一个可能的示例中，所述上行控制信令由多个小区中的每个小区采用连续多个频域资源块PRB进行传输，且所述每个小区使用不同的频域扩频序列以避免小区相互干扰。
可见，本设计中，通信系统的每个小区能够通过使用多个连续的PRB传输上行控制信令，从而降低不同小区的长时间上行控制信令的互相干扰。
在一个可能的示例中，所述多个时隙包括第一时隙和第二时隙，所述第一时隙中用于传输所述上行控制信令的符号的数量为N1，所述第二时隙中用于传输所述上行控制信令的符号的数量为N2，第一符号组和第三符号组采用同一频域资源即同频，第二符号组和第四符号组采用同频，或者，所述第一频域资源高于所述第二频域资源，且所述第三频域资源高于所述第四频域资源，或者，所述第一频域资源低于所述第二频域资源，且所述第三频域资源低于所述第四频域资源，N1、N2为大于1的整数；

下面结合具体的应用示例，对本发明实施例做进一步说明。
在第一个应用示例中，如图10所示，假设上行控制信令的符号长度为8个符号，时隙的长度为7个符号。在一个时隙中终端传输4个符号的上行控制信令的实施例如图10(a)所示。终端在第四个符号以及PRB X上传输DMRS参考信号，在第五个符号以及PRB X上传输UCI，在第六个符号以及PRB Y上传输DMRS，在第七个符号以及PRB Y上传输UCI。
终端在两个时隙中传输8个符号的上行控制信令的实施例如图10(b)所示。第一个时隙中，终端在第四个符号以及PRB X上传输DMRS参考信号，在第五个符号以及PRB X上传输UCI，在第六个符号以及PRB Y上传输DMRS，在第七个符号以及PRB Y上传输UCI； 第二个时隙中，终端在第四个符号以及PRB Y上传输DMRS参考信号，在第五个符号以及PRB Y上传输UCI，在第六个符号以及PRB X上传输DMRS，在第七个符号以及PRB X上传输UCI。
在网络侧，网络侧设备分别把DMRS对应的符号接收后，测量在PRB X和/或PRB Y上的信道信息，然后用UCI对应符号接收到的信号除以对应的信道信息得到控制信息。
在第二个应用示例中，如图11所示，假设上行控制信令的符号长度为10，时隙长度为7，针对长时间上行控制信令总时长为10个符号的实现方式，其中，本实施例中时隙的长度为7个符号。
在一个时隙中终端传输5个符号的上行控制信令的实施例如图11(a)所示。终端在第三个符号以及PRB X上传输DMRS参考信号，在第四个和第五个符号以及PRB X上传输UCI，在第六个符号以及PRB Y上传输DMRS，在第七个符号以及PRB Y上传输UCI。
在两个时隙中终端传输10个符号的上行控制信令的实施例如图11(b)所示。第一个时隙中，终端在第三个符号以及PRB X上传输DMRS参考信号，在第四个和第五个符号以及PRB X上传输UCI，在第六个符号以及PRB Y上传输DMRS，在第七个符号以及PRB Y上传输UCI；第二个时隙中，终端在第三个符号以及PRB Y上传输DMRS参考信号，在第四个和第五个符号以及PRB Y上传输UCI，在第六个符号以及PRB X上传输DMRS，在第七个符号以及PRB X上传输UCI。
此外，在一个时隙中终端传输5个符号的上行控制信令的实施例如图11(c)所示。终端在第三个符号以及PRB X上传输DMRS参考信号，在第四个符号以及PRB X上传输UCI，在第五个符号以及PRB Y上传输DMRS，在第六个和第七个符号以及PRB Y上传输UCI。
在两个时隙中终端传输10个符号的上行控制信令的实施例如图11(d)所示。第一个时隙中，终端在第三个符号以及PRB X上传输DMRS参考信号，在第四个符号以及PRB X上传输UCI，在第五个符号以及PRB Y上传输DMRS，在第六个和第七个符号以及PRB Y上传输UCI；第二个时隙中，终端在第三个符号以及PRB Y上传输DMRS参考信号，在第四个符号以及PRB Y上传输UCI，在第五个符号以及PRB X上传输DMRS，在第六个和第七个符号以及PRB X上传输UCI。
在网络侧，网络侧设备分别把DMRS对应的符号接收后，测量在PRB X和/或PRB Y上的信道信息，然后用UCI对应符号接收到的信号除以对应的信道信息得到控制信息。
