Description

一种发送、接收物理上行控制信道的方法及设备
本申请要求在2017年9月8日提交中国专利局、申请号为201710807057.6、申请名称为“一种发送、接收物理上行控制信道的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种发送、接收物理上行控制信道的方法及设备。
背景技术
在第五代移动通信技术(5G)中，能够支持不同的终端设备在相同的物理资源内实现复用，且不同的终端设备可使用不同长度的长物理上行控制信道(long physical uplink control channel，long PUCCH)。
当不同的终端设备在相同的物理资源内复用时，对于解调参考信号(demodulation reference signal，DMRS)来说，是采用序列正交的方式发送，即每个终端设备发送的DMRS都会占满DMRS符号上对应的12个资源单元(resource element，RE)，每个DMRS符号上的DMRS序列是一个长为12的序列，不同的终端设备发送的DMRS的序列对应的循环移位(cyclic shift)不同，即通过序列的循环移位实现不同终端设备发送的DMRS之间的正交。而终端设备在该物理资源内所发送的上行控制信息是采用DFT变换前加扰的正交覆盖码实现正交，则上行控制信息之间和DMRS之间采用的正交方式不同，那么，如果两个不同长度的long PUCCH在相同的物理资源内复用，就必须保证不同的long PUCCH的DMRS符号在1个时隙内是对齐的，例如，都占用1个时隙中14个符号中的第2个符号、第6个符号等，否则，如果一个终端设备发送的DMRS与另一个终端设备发送的其他的上行控制信息对齐，则无法保证彼此之间的正交，从而导致冲突。而如果DMRS对齐，则可能会导致某些长度的long PUCCH包含的DMRS数量不满足性能需求，可参考图1，其中画斜线的方框表示DMRS，当14符号的long PUCCH在一个long PUCCH资源中包含4个DMRS，这4个DMRS的位置固定在第1,5,8,12符号上时，另一个与其复用的5符号的long PUCCH在该物理资源内就只能包含第1个符号上的1个DMRS符号，从而可能导致使用5符号的long PUCCH的终端设备的信道估计性能较差。
发明内容
本申请提供一种发送、接收物理上行控制信道的方法及设备，用于增强终端设备的信道估计性能。
第一方面，提供一种发送物理上行控制信道的方法，该方法可由终端设备执行。该方法包括：生成物理上行控制信道，其中，所述物理上行控制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用 所述资源单元集合的部分频域子载波，所述部分频域子载波与所述上行控制信息在所述资源单元集合中占用的频域子载波相同；发送所述物理上行控制信道。
相应的，第二方面，提供一种接收物理上行控制信道的方法，该方法可由网络设备执行，网络设备例如为基站。该方法包括：接收终端设备发送的物理上行控制信道，其中，所述物理上行控制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用所述资源单元集合的部分频域子载波，所述部分频域子载波与所述上行控制信息在所述资源单元集合中占用的频域子载波相同；从所述物理上行控制信道获得所述解调参考信号和所述上行控制信息。
本申请实施例中，物理上行控制信道可以采用不跳频的方式发送，则可以认为资源单元集合包括一个资源单元子集。解调参考信号在资源单元集合的第一时域符号中可以占用部分频域子载波，从而一个终端设备发送的解调参考信号与其他的终端设备发送的上行控制信息可以在频域上实现复用，通过这种方式，在不同的终端设备在同一个资源单元集合内复用时，无需不同终端设备的解调参考信号对齐，使得解调参考信号的时域位置可以较为灵活，终端设备可根据情况确定解调参考信号的数量，从而有助于提高终端设备的信道估计性能。所述部分频域子载波与所述上行控制信息在所述资源单元集合中占用的频域子载波相同，从而根据上行控制信息在资源单元集合中占用的频域子载波就可以直接确定所述部分频域子载波，较为简单直接。
结合第一方面或第二方面，在一个可能的设计中，所述至少1个时域符号还包括第二时域符号，所述解调参考信号在所述第二时域符号上占用所述资源单元集合的全部频域子载波。
即，本申请实施例既可以支持解调参考信号通过comb的形式发送，也可以支持解调参考信号以占用全部的频域子载波的形式发送，从而既有助于实现解调参考信号的灵活分布，也有助于提高信道估计性能。
第三方面，提供一种发送物理上行控制信道的方法，该方法可由终端设备执行。该方法包括：生成物理上行控制信道，其中，所述物理上行控制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，所述资源单元集合包括第一资源单元子集和第二资源单元子集，所述第一资源单元子集包括的第一频域资源是连续的，所述第二资源单元子集包括的第二频域资源是连续的，并且，所述第一资源单元子集包括的所述第一频域资源和所述第二资源单元子集包括的所述第二频域资源相同或者不相同，所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用资源单元子集的部分频域子载波，所述部分频域子载波与所述上行控制信息在所述资源单元子集中占用的频域子载波相同，其中，所述资源单元子集为所述第一资源单元子集和/或所述第二资源单元子集；发送所述物理上行控制信道。
相应的，第四方面，提供一种接收物理上行控制信道的方法，该方法可由网络设备执行，网络设备例如为基站。该方法包括：接收终端设备发送的物理上行控制信道，其中，所述物理上行控制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，所述资源单元集合包括第一资源单元子集和第二资源单元子集，所述第 一资源单元子集包括的第一频域资源是连续的，所述第二资源单元子集包括的第二频域资源是连续的，并且，所述第一资源单元子集包括的所述第一频域资源和所述第二资源单元子集包括的所述第二频域资源相同或者不相同，所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用资源单元子集的部分频域子载波，所述部分频域子载波与所述上行控制信息在所述资源单元子集中占用的频域子载波相同，其中，所述资源单元子集为所述第一资源单元子集和/或所述第二资源单元子集；从所述物理上行控制信道获得所述解调参考信号和所述上行控制信息。
本申请实施例中，物理上行控制信道也可以采用跳频的方式发送，则可以认为资源单元集合包括第一资源单元子集和第二资源单元子集。解调参考信号在资源单元子集的第一时域符号中可以占用部分频域子载波，从而一个终端设备发送的解调参考信号与其他的终端设备发送的上行控制信息可以在频域上实现复用，通过这种方式，在不同的终端设备在同一个资源单元集合内复用时，无需不同终端设备的解调参考信号对齐，使得解调参考信号的时域位置可以较为灵活，终端设备可根据情况确定解调参考信号的数量，从而有助于提高终端设备的信道估计性能。所述部分频域子载波与所述上行控制信息在所述资源单元集合中占用的频域子载波相同，从而根据上行控制信息在资源单元集合中占用的频域子载波就可以直接确定所述部分频域子载波，较为简单直接。
结合第三方面或第四方面，在一个可能的设计中，所述至少1个时域符号还包括第二时域符号，所述解调参考信号在所述第二时域符号上占用所述资源单元子集的全部频域子载波。
其中，第一时域符号和第二时域符号可以位于一个资源单元子集中，或者也可以位于不同的资源单元子集中，本申请实施例不做限制。本申请实施例既可以支持解调参考信号通过comb的形式发送，也可以支持解调参考信号以占用全部的频域子载波的形式发送，从而既有助于实现解调参考信号的灵活分布，也有助于提高信道估计性能。
结合第一方面、第二方面、第三方面或第四方面，在一个可能的设计中，终端设备在生成物理上行控制信道之前，还根据所述上行控制信息所占用的频域子载波，确定所述解调参考信号所占用的频域子载波。相应的，网络设备在接收物理上行控制信道之前，还根据所述上行控制信息所占用的频域子载波，确定所述解调参考信号所占用的频域子载波。
在本申请实施例中，解调参考信号在第一时域符号中是占用资源单元集合或资源单元子集的部分频域子载波，因此终端设备和网络设备都需要确定解调参考信号所占用的部分频域子载波，从而才能确定解调参考信号在频域的位置。确定解调参考信号占用的部分频域子载波，有多种方式，因为所述部分频域子载波与所述控制信息在资源单元集合或资源单元子集中占用的频域子载波相同，因此其中一种方式是通过上行控制信息所占用的频域子载波来直接确定解调参考信号所占用的频域子载波，较为简单。
结合第一方面、第二方面、第三方面或第四方面，在一个可能的设计中，终端设备在生成物理上行控制信道之前，还根据所述物理上行控制信道的资源索引与所述上行控制信息占用的频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述上行控制信息所占用的频域子载波。相应的，网络设备在接收物理上行控制信道之前，还根据所述物理上行控制信道的资源索引与所述上行控制信息占用的频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述上行控制信息所占用的频域子 载波。
终端设备可以确定该终端设备传输所述上行控制信息所使用的物理上行控制信道的资源索引，从而就可以确定上行控制信息所占用的频域子载波，而在确定上行控制信息占用的频域子载波后，也就可以相应确定所述部分频域子载波。网络设备也是采用相同的确定方式。

根据所述部分频域子载波与所述上行控制信息对应的正交码之间的对应关系确定所述部分频域子载波，是确定所述部分频域子载波的另一种方式。
结合第一方面、第二方面、第三方面或第四方面，在一个可能的设计中，终端设备在生成物理上行控制信道之前，还根据所述物理上行控制信道的资源索引与所述上行控制信息对应的正交码之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述正交码。相应的，网络设备在接收物理上行控制信道之前，还根据所述物理上行控制信道的资源索引与所述上行控制信息对应的正交码之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述正交码。

相应的，第八方面，提供一种接收物理上行控制信道的方法，该方法可由网络设备执行，网络设备例如为基站。该方法包括：接收物理上行控制信道，其中，所述物理上行控 制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，所述资源单元集合包括第一资源单元子集和第二资源单元子集，所述第一资源单元子集包括的第一频域资源是连续的，所述第二资源单元子集包括的第二频域资源是连续的，并且，所述第一资源单元子集包括的所述第一频域资源和所述第二资源单元子集包括的所述第二频域资源相同或者不相同，所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用资源单元子集的部分频域子载波，所述资源单元子集为所述第一资源单元子集和/或所述第二资源单元子集，所述部分频域子载波的索引基于所述上行控制信息对应的正交码确定；从所述物理上行控制信道获得所述解调参考信号和所述上行控制信息。
物理上行控制信道也可以采用跳频的方式发送，则可以认为资源单元集合包括第一资源单元子集和第二资源单元子集。解调参考信号在资源单元子集的第一时域符号中可以占用部分频域子载波，从而一个终端设备发送的解调参考信号与其他的终端设备发送的上行控制信息可以在频域上实现复用，通过这种方式，在不同的终端设备在同一个资源单元集合内复用时，无需不同终端设备的解调参考信号对齐，使得解调参考信号的时域位置可以较为灵活，终端设备可根据情况确定解调参考信号的数量，从而有助于提高终端设备的信道估计性能。
所述部分频域子载波的索引可以基于所述上行控制信息对应的正交码确定，较为简单。
结合第七方面或第八方面，在一个可能的设计中，所述至少1个时域符号还包括第二时域符号，所述解调参考信号在所述第二时域符号上占用所述资源单元子集的全部频域子载波。
其中，第一时域符号和第二时域符号可以位于一个资源单元子集中，或者也可以位于不同的资源单元子集中，本申请实施例不做限制。本申请实施例既可以支持解调参考信号通过comb的形式发送，也可以支持解调参考信号以占用全部的频域子载波的形式发送，从而既有助于实现解调参考信号的灵活分布，也有助于提高信道估计性能。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备：也可以称之为终端，包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、智能手表、智能头盔、智能眼镜、智能手环、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
2)网络设备，例如包括基站(例如，接入点)，可以是指接入网中在空中接口上通过 一个或多个小区与无线终端设备通信的设备。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站还可协调对空中接口的属性管理。例如，基站可以包括LTE系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)，本申请实施例并不限定。
3)物理上行控制信道，例如为PUCCH，或者为long PUCCH，本申请实施例不做限制。
4)long PUCCH，在5G系统中，已经支持了long PUCCH的发送，long PUCCH在时域上可能占用1个时隙(slot)中的4个，5个，……，14个正交频分复用(orthogonal frequency division multiplexing，OFDM)/离散傅里叶变换扩频的正交频分复用多址接入(discrete fourier transform spread OFDM，DFT-s-OFDM)符号，long PUCCH在时域上占用的OFDM/DFT-s-OFDM符号的示例可参考图2，其中画斜线的方框代表long PUCCH在时域上占用的OFDM/DFT-s-OFDM符号。

5)解调参考信号，例如为DMRS，用于物理上行共享信道(physical uplink shared channel，PUSCH)或PUCCH的相关解调。
6)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“和/或”，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。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
本文所提供的技术方案可以应用于5G新无线(new radio，NR)系统，或者下一代移动通信系统，或者是其他类似的通信系统。
如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术背景。
在5G系统中，为了提高资源利用效率，long PUCCH已经支持了传输中等数量(moderate payload)的上行控制信息(uplink control information，UCI)，且支持一定的复用能力。例如，在一个PRB内，这种传输中等数量的UCI的long PUCCH格式能够传输几个比特到十几个比特，同时，在这个PRB内，支持2个或更多终端设备同时发送。
由于long PUCCH在时域上支持了4符号长度～14符号长度的发送，因此在一个资源单元集合中，可能存在不同长度的long PUCCH复用的情况。例如，1个占用14符号的long PUCCH与另1个占用5符号的long PUCCH的复用。因此，如何设计long PUCCH的结构，使得不同长度的long PUCCH能够在相同的物理资源内复用，成为了一个亟待解决的问题。
在长期演进(long term evolution，LTE)系统中，支持LTE PUCCH格式(format)5，这种格式支持2个终端设备在相同的物理资源内同时发送UCI。其中，UCI在一个DFT-s-OFDM符号的发送方法为，通过对调制符号的同号重复或反号重复，使得调制符号在通过12点的离散傅里叶变换(discrete fourier transform，DFT)变换后，在频域形成梳 齿(comb)。可参考图3，例如，将终端设备a发送的调制符号a0,a1,a2,a3,a4,a5进行同号重复，得到a0,a1,a2,a3,a4,a5，则终端设备a发送的调制符号变为a0,a1,a2,a3,a4,a5,a0,a1,a2,a3,a4,a5，将a0,a1,a2,a3,a4,a5,a0,a1,a2,a3,a4,a5进行12点的DFT变换，得到12个元素，其中奇数索引的元素(1,3,5,7,9,11)的数值为0，偶数索引的元素(0,2,4,6,8,10)的数值为非0，即，得到的12个元素为(a0',0，a1',0，a2',0，a3',0，a4',0,a5',0)；将终端设备b发送的调制符号b0,b1,b2,b3,b4,b5进行反号重复，得到-b0,-b1,-b2,-b3,-b4,-b5，则终端设备b发送的调制符号变为b0,b1,b2,b3,b4,b5,-b0,-b1,-b2,-b3,-b4,-b5，将b0,b1,b2,b3,b4,b5,-b0,-b1,-b2,-b3,-b4,-b5进行12点的DFT变换，也得到12个元素，其中奇数索引的元素(1,3,5,7,9,11)的数值为非0，偶数索引的元素(0,2,4,6,8,10)的数值为0，即，得到的12个元素为(0,b0',0,b1',0,b2',0,b3',0,b4',0,b5')，则终端设备a和终端设备b复用后，在一个符号上发送的信息为(a0',b0',a1',b1',a2',b2',a3',b3',a4',b4',a5',b5')，如图3的右侧所示。通过这种“梳齿(comb)”状的发送结构，两个不同长度的long PUCCH在相同的物理资源内复用时，通过频域的正交可避免终端设备间上行控制信息的干扰。所谓comb，可以形象地理解为，一个终端设备所发送的上行控制信息，在一个OFDM符号或DFT-s-OFDM符号对应的RE中是等间隔分布的，类似于梳子的齿。
尽管LTE PUCCH format 5能够保证不同长度的long PUCCH的UCI间的正交性，但是对于DMRS来说，是采用序列正交的方式发送，即每个终端设备发送的DMRS都会在DMRS符号上占满12个RE，每个DMRS可看做是一个长为12的序列，不同的终端设备发送的DMRS的序列对应的循环移位不同，即通过序列的循环移位实现不同终端设备发送的DMRS之间的正交。可见，DMRS的正交方式与UCI的正交方式不同，那么，如果两个不同长度的long PUCCH在相同的物理资源内复用，就必须保证不同的long PUCCH的DMRS符号在1个时隙内是对齐的，例如，都占用1个时隙中14个符号中的第2个符号、第3个符号、或第6个符号等，可参考图4，为如前举例中的终端设备a和终端设备b复用的示意，在图4中，以DMRS在1个时隙中占用第3个符号为例。否则，如果一个终端设备发送的DMRS与另一个终端设备发送的其他的上行控制信息对齐，则无法保证彼此之间的正交，从而导致冲突。而如果DMRS对齐，则可能会导致某些长度的long PUCCH包含的DMRS数量不满足性能需求，可继续参考图1，当14符号的long PUCCH的DMRS的位置固定在第1,5,8,12符号上时，另一个与其复用的5符号的long PUCCH就只能包含1个DMRS符号，从而可能导致使用5符号的long PUCCH的终端设备的信道估计性能较差。
鉴于此提供本申请实施例的技术方案，以增强终端设备的信道估计性能。
下面介绍本申请实施例的一种应用场景，请参考图5，为该应用场景的示意图。图5中包括网络设备和终端设备，网络设备和终端设备可实现信息交互。例如终端设备可生成物理上行控制信道，并向网络设备发送物理上行控制信道，则网络设备可接收终端设备发送的物理上行控制信道。图5中的网络设备例如为接入网(access network，AN)设备，例如基站。其中，因为本申请实施例的方案主要涉及的是接入网设备和终端设备，因此图5中未画出核心网设备。其中，接入网设备例如为NR系统中的gNB。
请参见图6，本申请实施例提供一种发送物理上行控制信道的方法，在下文的介绍过程中，以该方法应用在图5所示的应用场景为例。该方法的流程介绍如下。
S61、在终端设备接入网络时或终端设备接入网络后，网络设备为终端设备配置long  PUCCH的资源集合，则终端设备确定网络设备所配置的long PUCCH资源集合。
例如网络设备可通过高层信令为终端设备配置long PUCCH的资源集合，则终端设备接收网络设备发送的高层信令后就可以确定long PUCCH的资源集合，高层信令例如为无线资源控制(radio resource control，RRC)信令。
或者网络设备可通过初始接入过程中的消息(Msg)2或Msg4信令为终端设备配置long PUCCH的资源集合，则终端设备接收网络设备发送的Msg2或Msg4信令后就可以确定long PUCCH的资源集合。
其中，该资源集合可以包含至少1个long PUCCH资源，可选地，该资源集合可以包含2个long PUCCH资源、4个long PUCCH资源、7个long PUCCH资源或8个long PUCCH资源，本申请实施例不做限制。在配置该资源集合后，终端设备后续在发送long PUCCH时，就可以采用该资源集合中的long PUCCH资源来发送。
S62、网络设备向终端设备发送第一信令，则终端设备接收第一信令。
作为一种示例，第一信令为高层信令，例如RRC信令，该第一信令可以指示终端设备向网络设备发送周期信道状态信息(channel state information，CSI)等信号，并指示该信号所使用的long PUCCH资源。
作为另一种示例，第一信令也可以是承载在物理下行控制信道中的信令，物理下行控制信道例如为物理下行控制信道(physical downlink control channel，PDCCH)，例如第一信令为下行控制信息(downlink control information，DCI)，该第一信令可以用于向终端设备调度下行数据，并显示或隐式指示用于反馈该下行数据的应答信息所使用的long PUCCH资源，应答信息例如为肯定应答(ACK)/否定应答(NACK)。则，如果第一信令为DCI，那么网络设备在向终端设备发送第一信令后，还会通过物理下行共享信道向终端设备发送下行数据且通过DCI中的字段显示通知终端设备反馈应答信息所使用的long PUCCH资源，物理下行共享信道例如为物理下行共享信道(physical downlink shared channel，PDSCH)，则终端设备可通过PDSCH接收下行数据，且终端设备可通过PUCCH反馈下行数据对应的应答信息。
当然第一信令也可以有其他的实现形式，本申请实施例不做限制。
其中，S61和S62均为可选的步骤。
S63、终端设备生成物理上行控制信道。
其中，所述物理上行控制信道承载解调参考信号和上行控制信息，所述物理上行控制信道在资源单元集合上发送，资源单元集合用于传输PUCCH。如果PUCCH不采用跳频的方式发送，所述资源单元集合在时域上占用至少2个时域符号，所述资源单元集合包括的频域资源是连续的，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用所述资源单元集合的部分频域子载波。示例性的，请参考图7A，如果PUCCH不采用跳频的方式发送，则所述资源单元集合在时域上可以占用14个时域符号，即图7B中的时域符号0～时域符号13，且所述资源单元集合在频域上可以占用12个频域子载波，即图7B中的频域子载波0～频域子载波11。或者，所述资源单元集合在时域上也可以占用其他数量的时域符号，例如占用7个时域符号，本申请实施例不做限制。
需要说明的是，因为资源单元集合在时域上占用至少2个时域符号，所以，所述解调参考信号在所述第一时域符号上占用所述资源单元集合的部分频域子载波，是指所述解调 参考信号占用的是该资源单元集合中与第一时域符号对应的频域子载波中的部分频域子载波，而并不是说该资源单元集合只包括第一时域符号上的频域子载波。
例如，所述物理上行控制信道在所述资源单元集合上发送，则该资源单元集合在时域上占用至少2个时域符号，该资源单元集合在频域上占用连续的频域子载波，所述解调参考信号位于该资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用该资源单元集合的部分频域子载波。
也就是说，在第一时域符号上，所述解调参考信号并不占用所述资源单元集合包括的全部频域子载波，而只是占用了所述资源单元集合所包括的全部频域子载波中的部分频域子载波。
所述第一时域符号可以包括一个时域符号或多个时域符号，若所述第一时域符号包括一个时域符号，则所述解调参考信号在该时域符号中占用所述资源单元集合的部分频域子载波，若所述第一时域符号包括多个时域符号，则所述解调参考信号在该多个时域符号中的每个时域符号中都占用所述资源单元集合的部分频域子载波。
示例性的，所述至少1个时域符号还包括第二时域符号，所述解调参考信号在所述第二时域符号上占用所述资源单元集合的全部频域子载波。例如所述资源单元集合在时域上占用时域符号0～时域符号6，在频域上占用频域子载波0～频域子载波11，所述解调参考信号位于其中的符号1和符号5上，其中符号1为第一时域符号，符号5为第二时域符号，所述解调参考信号在符号1上占用该资源单元集合的部分频域子载波，例如所述解调参考信号在符号1上占用的频域子载波的索引为{0,2,4,6,8,10}，而所述解调参考信号在符号5上占用的频域子载波为频域子载波0～频域子载波11。即，本申请实施例既可以支持解调参考信号通过comb的形式发送，也可以支持解调参考信号占用全部的频域子载波的形式发送，从而既有助于实现解调参考信号的灵活分布，也有助于提高信道估计性能。
如上介绍的是PUCCH不采用跳频方式发送的情况，如果PUCCH采用跳频的方式发送，所述资源单元集合在时域上同样占用至少2个时域符号，例如所述资源单元集合在时域上可以占用4～14个时域符号。所述资源单元集合包括第一资源单元子集和第二资源单元子集，第一资源单元子集与第二资源单元子集在时域上占用不同的时域符号，第一资源单元子集包括的频域资源称为第一频域资源，第一频域资源是连续的，第二资源单元子集包括的频域资源称为第二频域资源，第二频域资源是连续的。并且，第一资源单元子集包括的第一频域资源和第二资源单元子集包括的第二频域资源相同或者不相同。所述资源单元集合在时域上占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用资源单元子集的部分频域子载波，所述部分频域子载波与所述上行控制信息在所述资源单元子集中占用的频域子载波相同，其中，所述资源单元子集为第一资源单元子集和/或第二资源单元子集。
可参考图7B，例如第一资源单元子集在时域上占用时域符号0～时域符号6，第二资源单元子集在时域上占用时域符号7～时域符号13，第一资源单元子集和第二资源单元子集总共占用14个符号。图7A以所述第一频域资源和所述第二频域资源不同为例，第一频域资源包括频域子载波0～频域子载波5，第二频域资源包括频域子载波6～频域子载波11。
例如，所述资源单元子集为所述第一资源单元子集，且所述上行控制信息在所述第一资源单元子集中占用的频域子载波的索引为{0,2,4,6,8,10}，则所述解调参考信号在所述第 一资源单元子集中占用的频域子载波的索引也为{0,2,4,6,8,10}。
或者，所述资源单元子集为所述第二资源单元子集，且所述上行控制信息在所述第二资源单元子集中占用的频域子载波的索引为{12,14,16,18,20,22}，则所述解调参考信号在所述第一资源单元子集中占用的频域子载波的索引也为{12,14,16,18,20,22}。
或者，所述资源单元子集为所述第一资源单元子集和所述第二资源单元子集，所述上行控制信息在所述第一资源单元子集中占用的频域子载波的索引为{0,2,4,6,8,10}，在所述第二资源单元子集中占用的频域子载波的索引为{12,14,16,18,20,22}，则所述解调参考信号在所述第一资源单元子集中占用的频域子载波的索引为{0,2,4,6,8,10}，在所述第二资源单元子集中占用的频域子载波的索引为{12,14,16,18,20,22}。
即，所述部分频域子载波与所述上行控制信息在所述资源单元子集中占用的频域子载波相同，是对于同一个资源单元子集来说，所述部分频域子载波和所述上行控制信息占用的频域子载波相同。
同样，因为资源单元集合在时域上占用至少两个时域符号，所以，所述解调参考信号在所述第一时域符号上占用一个资源单元集合的部分频域子载波，是指所述解调参考信号占用的是该资源单元集合中与第一时域符号对应的频域子载波中的部分频域子载波，而并不是说该资源单元集合只包括第一时域符号上的频域子载波。
例如，所述物理上行控制信道在第一资源单元子集和第二资源单元子集上发送，则这两个资源单元子集中的每个资源单元子集在时域上都占用至少2个时域符号，所述解调参考信号位于所述资源单元集合的至少1个时域符号上，这包括三种情况：1、所述解调参考信号位于第一资源单元子集的至少1个时域符号上；2、所述解调参考信号位于第二资源单元子集的至少1个时域符号上；3、所述解调参考信号位于第一资源单元子集和第二资源单元子集上，且在第一资源单元子集和第二资源单元子集中共占用至少1个时域符号。所述至少1个时域符号包括第一时域符号，所述解调参考信号在所述第一时域符号上占用相应的资源单元子集包括的频域子载波中的部分频域子载波。例如，所述解调参考信号位于第一资源单元子集的至少1个时域符号上，则所述解调参考信号在所述第一时域符号上占用第一资源单元子集的部分子载波，或者，所述解调参考信号位于第二资源单元子集的至少1个时域符号上，则所述解调参考信号在所述第一时域符号上占用第二资源单元子集的部分频域子载波，或者，所述解调参考信号位于第一资源单元子集和第二资源单元子集的至少1个时域符号上，则所述第一时域符号可能包括至少2个时域符号，所述解调参考信号在位于第一资源单元子集内的所述第一时域符号上占用第一资源单元子集的部分频域子载波，以及在位于第二资源单元子集内的所述第一时域符号上占用第二资源单元子集的部分频域子载波。
也就是说，在第一时域符号上，所述解调参考信号并不占用相应的资源单元子集包括的全部频域子载波，而只是占用了相应的资源单元子集所包括的全部频域子载波中的部分频域子载波。
第一时域符号可以包括一个时域符号或多个时域符号，若第一时域符号包括一个时域符号，则解调参考信号在该时域符号中占用相应的资源单元子集的部分频域子载波；如前也涉及了第一时域符号包括多个时域符号的情况，若第一时域符号包括多个时域符号，则解调参考信号在该多个时域符号中的每个时域符号中都占用相应的资源单元子集的部分频域子载波。
这里所述的相应的资源单元子集，可以理解为包含第一时域符号的资源单元子集。例如一个资源单元子集在时域上占用时域符号0～时域符号6，在频域上占用频域子载波0～频域子载波11，解调参考信号位于其中的符号1上，则解调参考信号在符号1上占用该资源单元子集的部分频域子载波，例如解调参考信号在符号1上占用的频域子载波的索引为{0,2,4,6,8,10}。
另外，在一个物理上行控制信道中，上行控制信息和解调参考信号不占用相同的时域符号。
示例性的，所述至少1个时域符号还包括第二时域符号，所述解调参考信号在所述第二时域符号上占用所述资源单元子集的全部频域子载波。例如一个资源单元集合在时域上占用时域符号0～时域符号13，在频域上占用频域子载波0～频域子载波11，所述解调参考信号位于其中的符号1和符号8上，其中符号1为第一时域符号，符号8为第二时域符号，所述解调参考信号在符号1上占用该资源单元集合的部分频域子载波，例如所述解调参考信号在符号1上占用的频域子载波的索引为{0,2,4,6,8,10}，而所述解调参考信号在符号8上占用的频域子载波为频域子载波0～频域子载波11。即，本申请实施例既可以支持解调参考信号通过comb的形式发送，也可以支持解调参考信号占用全部的频域子载波的形式发送，从而既有助于实现解调参考信号的灵活分布，也有助于提高信道估计性能。
另外，所述第一时域符号和所述第二时域符号可以位于同一个资源单元子集内，也可以位于不同的资源单元子集内。例如所述第一时域符号和所述第二时域符号可以都位于第一资源单元子集内或第二资源单元子集内，在这种情况下，没有包含所述第一时域符号和所述第二时域符号的资源单元子集中的第三时域符号也可以承载解调参考信号，则该解调参考信号在第三时域符号上可以占用该没有包含所述第一时域符号和所述第二时域符号的资源单元子集的部分频域子载波，或全部频域子载波。或者，所述第一时域符号位于第一资源单元子集内，所述第二时域符号位于第二资源单元子集内，或者，所述第一时域符号位于第二资源单元子集内，所述第二时域符号位于第一资源单元子集内，本申请实施例不做限制。
一个RE可以由时域上的1个OFDM符号或DFT-s-OFDM符号、以及频域上的1个子载波构成。
其中，时域符号例如为OFDM符号或DFT-s-OFDM符号。
如果S62中的第一信令为高层信令，则所述上行控制信息可以包括CSI等信息，如果S62中的第一信令为DCI，则所述上行控制信息可以包括ACK/NACK等信息。
在本申请实施例中，DMRS在第一时域符号中是占用资源单元集合或所述资源单元子集的部分频域子载波，因此终端设备需要确定DMRS所占用的部分频域子载波，从而才能确定DMRS在频域的位置。则在S63之前，即在终端设备生成物理上行控制信道之前，该终端设备先要确定所述部分频域子载波，如下介绍终端设备先确定所述部分频域子载波的方式。
作为一种示例，在本申请实施例中可通过子载波原则来确定解调参考信号所占用的部分频域子载波，所谓的子载波原则为：所述部分频域子载波与所述上行控制信息在资源单元集合或所述资源单元子集中占用的频域子载波相同。
其中，要确定两个频域子载波相同，可以通过频域子载波的频域索引来确定，如果两个频域子载波的频域索引相同，则表明两个频域子载波相同。这里的频域索引相同，有两 种不同的情况：
情况1、在一个资源单元集合中，每个OFDM符号或DFT-s-OFDM符号对应的频域子载波都是单独编号，例如都按照频率从低到高的顺序，将每个OFDM符号或DFT-s-OFDM符号对应的频域子载波编号为0～11。
在这种情况下，DMRS在资源单元集合中所占用的频域子载波的频域索引，与所述上行控制信息在所述资源单元集合中占用的频域子载波的频域索引直接相同，例如DMRS在资源单元集合中所占用的频域子载波的频域索引为{1,3,5,7,9,11}，则所述上行控制信息在所述资源单元集合中占用的频域子载波的频域索引也是{1,3,5,7,9,11}，只是DMRS与所述上行控制信息在所述资源单元集合中占用的OFDM符号或DFT-s-OFDM符号不同。
在下文的介绍过程中，如无特殊说明，在对索引举例时均是以情况1的形式为例。
情况2、在一个资源单元集合中，每个OFDM符号或DFT-s-OFDM符号对应的频域子载波不是单独编号，而是整个资源单元集合统一编号，例如一个资源单元集合中按照频率从低到高的顺序，将第0个OFDM符号或DFT-s-OFDM符号对应的频域子载波编号为0～11，将第1个OFDM符号或DFT-s-OFDM符号对应的频域子载波编号为12～23，以此类推。
在这种情况下，DMRS在资源单元集合中所占用的频域子载波的频域索引模12后的结果，与所述上行控制信息在所述资源单元集合中占用的频域子载波的频域索引模12后的结果相同。例如DMRS在资源单元集合中所占用的频域子载波的频域索引为{1,3,5,7,9,11}，则1,3,5,7,9,11分别模12，得到{1,3,5,7,9,11}，而所述上行控制信息在资源单元集合中占用的频域子载波的频域索引是{13,15,17,19,21,23}，则13,15,17,19,21,23分别模12，也为{1,3,5,7,9,11}，可见，DMRS在资源单元集合中所占用的频域子载波的频域索引模12后的结果，与所述上行控制信息在所述资源单元集合中占用的频域子载波的频域索引模12后的结果是相同的。
作为另一种示例，在本申请实施例中还可通过正交覆盖码(orthogonal cover code，OCC)原则来确定解调参考信号所占用的部分频域子载波，下文将正交覆盖码简称为正交码，则正交覆盖码原则也可简称为正交码原则。所谓的正交码原则为：所述部分频域子载波的索引基于所述上行控制信息对应的正交码确定。即，可以根据所述上行控制信息对应的正交码来确定所述部分频域子载波的索引。
如上介绍了确定所述部分频域子载波的两种原则，下面就介绍终端设备如何根据如上两种原则确定所述部分频域子载波。其中，确定所述部分频域子载波，可以通过确定所述部分频域子载波的索引实现。其中，终端设备根据如上两种原则，可以采用不同的方式来确定部分频域子载波，以下介绍几种方式。
1、直接确定方式。
在直接确定方式下，终端设备根据所述上行控制信息所占用的频域子载波，确定所述解调参考信号所占用的频域子载波。可以看到，在直接确定方式中需要用到所述上行控制信息所占用的频域子载波，作为一种示例，终端设备可以根据所述物理上行控制信道的资源索引(PUCCH index)与所述上行控制信息占用的频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述上行控制信息所占用的频域子载波。
对于终端设备来说，在要向网络设备发送物理上行控制信道时，既要通过该物理上行控制信道向网络设备发送DMRS，也要通过该物理上行控制信道向网络设备发送所述上行 控制信息，例如，如果S62中的第一信令为高层信令，则所述上行控制信息可以包括CSI，如果S62中的第一信令为承载在物理下行控制信道中的信令，则所述上行控制信息可以包括应答信息，例如为ACK/NACK。
具体的，终端设备通过S62中动态信令的隐式指示或显示指示，可以确定该终端设备传输所述上行控制信息所使用的物理上行控制信道的资源索引，并通过该物理上行控制信道的资源索引直接确定传输所述上行控制信息所使用频域子载波。协议可以预先规定所述部分频域子载波与所述上行控制信息所使用频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引与所述上行控制信息所使用频域子载波之间的对应关系，或者这两种对应关系也可以由网络设备事先设置，或者由网络设备和终端设备事先协商确定，本申请实施例不做限制，总之，终端设备可以事先存储所述部分频域子载波与所述上行控制信息所使用频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引与所述上行控制信息所使用频域子载波之间的对应关系，从而终端设备就可以确定DMRS所占用的所述部分频域子载波。
例如，PUCCH不通过跳频方式发送，当1个资源单元集合包含2个comb时，一种实现方式是奇数的物理上行控制信道的资源索引对应的上行控制信息占用的频域子载波的索引为奇数(1,3,5,7,9,11)，则奇数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为奇数(1,3,5,7,9,11)，偶数的物理上行控制信道的资源索引对应的上行控制信息占用的频域子载波的索引为偶数(0,2,4,6,8,10)，则偶数的PUCCH index对应的DMRS占用的频域子载波的索引为偶数(0,2,4,6,8,10)。
2、正交码确定方式。
在正交码确定方式下，终端设备根据所述部分频域子载波与所述上行控制信息对应的正交码之间的对应关系以及所述正交码，确定所述部分频域子载波。可以看到，在正交码确定方式中需要用到所述上行控制信息对应的正交码，作为一种示例，终端设备可以根据所述物理上行控制信道的资源索引与所述上行控制信息对应的正交码之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述上行控制信息对应的正交码。
具体的，终端设备通过S62中动态信令的隐式指示或显示指示，可以确定该终端设备传输所述上行控制信息所使用的物理上行控制信道的资源索引，并通过该物理上行控制信道的资源索引确定传输所述上行控制信息所对应的正交码。协议可以预先规定所述部分频域子载波与所述上行控制信息对应的正交码之间的对应关系，以及所述物理上行控制信道的资源索引与所述上行控制信息对应的正交码之间的对应关系，或者这两种对应关系也可以由网络设备事先设置，或者由网络设备和终端设备事先协商确定，本申请实施例不做限制，总之，终端设备可以事先存储所述部分频域子载波与所述上行控制信息对应的正交码之间的对应关系，以及所述物理上行控制信道的资源索引与所述上行控制信息对应的正交码之间的对应关系，从而终端设备就可以确定DMRS所占用的所述部分频域子载波。
举例来说，在所述部分频域子载波与所述上行控制信息对应的正交码之间的对应关系中，包括以下的至少一种情况：
在1个资源单元集合包含2个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,+1,+1,+1,+1,+1,+1,+1,+1,+1,+1}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{0,2,4,6,8,10}；或，

在1个资源单元集合包含4个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,+1,-1,-1,-1,+1,+1,+1,-1,-1,-1}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{2,6,10}；或，
在1个资源单元集合包含4个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,+1,-j,-j,-j,-1,-1,-1,+j,+j,+j}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{3,7,11}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,+1,+1,+1,+1,+1,+1,+1,+1,+1,+1}时，所述部分频域子载波的索引为{0,6}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,exp(j*1*π/3),exp(j*1*π/3),exp(j*2*π/3),exp(j*2*π/3),-1,-1,exp(j*4*π/3),exp(j*4*π/3),exp(j*5*π/3),exp(j*5*π/3)}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{1,7}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,exp(j*2*π/3),exp(j*2*π/3),exp(j*4*π/3),exp(j*4*π/3),+1,+1,exp(j*2*π/3),exp(j*2*π/3),exp(j*4*π/3),exp(j*4*π/3)}时，所述部分频域子载波的索引为{2,8}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,-1,-1,+1,+1,-1,-1,+1,+1,-1,-1}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{3,9}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所 述上行控制信息所对应的正交码为{+1,+1,exp(j*4*π/3),exp(j*4*π/3),exp(j*2*π/3),exp(j*2*π/3),+1,+1,exp(j*4*π/3),exp(j*4*π/3),exp(j*2*π/3),exp(j*2*π/3)}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{4,10}；或，
在1个资源单元集合包含6个comb的情况下，当通过该物理上行控制信道发送的所述上行控制信息所对应的正交码为{+1,+1,exp(j*5*π/3),exp(j*5*π/3),exp(j*4*π/3),exp(j*4*π/3),-1,-1,exp(j*2*π/3),exp(j*2*π/3),exp(j*1*π/3),exp(j*1*π/3)}时，终端设备可确定DMRS占用的所述部分频域子载波的索引为{5,11}。

其他也是类似。

例如，PUCCH不通过跳频方式发送，当1个资源单元集合包含2个comb时，一种实现方式是，奇数的物理上行控制信道的资源索引对应上行控制信息使用的正交码为(1,1,1,1,1,1,-1,-1,-1,-1,-1,-1)，则奇数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为奇数(1,3,5,7,9,11)，偶数的物理上行控制信道的资源索引对应的上行控制信息使用的正交码为(1,1,1,1,1,1,1,1,1,1,1,1)，则偶数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为偶数(0,2,4,6,8,10)。
3、物理上行控制信道确定方式。
在物理上行控制信道确定方式中，终端设备可以根据该物理上行控制信道的资源索引来确定DMRS所占用的所述部分频域子载波。其中，物理上行控制信道的资源索引是一种虚拟PUCCH资源索引，物理上行控制信道的资源索引到PUCCH所占用的物理资源之间存在确定的映射关系。例如在PUCCH不采用跳频方式发送时，物理上行控制信道占用的物理资源为PRB{1,2,3,4,97,98,99,100}，且每个物理上行控制信道只能用1个PRB，则虚拟PUCCH资源索引(即物理上行控制信道的资源索引)为{1,2,3,4,5,6,7,8}，这8个资源索引与8个PRB存在确定的1对1的映射关系，例如，索引1对应PRB1，以此类推。
例如，终端设备根据所述物理上行控制信道的资源索引确定所述部分频域子载波，可通过以下方式实现：终端设备根据所述物理上行控制信道的资源索引和所述部分频域子载波之间的对应关系，以及所述物理上行控制信道的资源索引，确定所述部分频域子载波。
具体的，终端设备通过S62中动态信令的隐式指示或显示指示，可以确定该终端设备传输所述上行控制信息所使用的物理上行控制信道的资源索引。协议可以预先规定所述物理上行控制信道的资源索引和所述部分频域子载波之间的对应关系，或者所述物理上行控制信道的资源索引和所述部分频域子载波之间的对应关系也可以由网络设备事先设置，或者由网络设备和终端设备事先协商确定，本申请实施例不做限制，总之，终端设备可以事先存储所述物理上行控制信道的资源索引和所述部分频域子载波之间的对应关系，而终端设备也知晓所述物理上行控制信道的资源索引，因此终端设备就可以确定DMRS所占用的所述部分频域子载波。这种方式较为简单直接。
例如，当1个资源单元集合包含2个comb时，一种实现方式是，奇数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为奇数(1,3,5,7,9,11)；偶数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为偶数(0,2,4,6,8,10)；或者，另一种实现方法是，偶数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为奇数(1,3,5,7,9,11)，奇数的物理上行控制信道的资源索引对应的DMRS占用的频域子载波的索引为偶数(0,2,4,6,8,10)。
或者例如，当1个资源单元集合包含3个comb时，一种实现方式是，物理上行控制信道的资源索引mod 3＝0时，DMRS占用的频域子载波的索引为奇数(0,3,6,9)；物理上行控制信道的资源索引mod 3＝1时，DMRS占用的频域子载波的索引为奇数(1,4,7,10)；物理上行控制信道的资源索引mod 3＝2时，DMRS占用的频域子载波的索引为偶数(2,5,8,11)，等等。mod代表取模运算。
无论是通过所述上行控制信息所占用的频域子载波、通过正交码、还是通过物理上行控制信道的资源索引来确定DMRS占用的所述部分频域子载波，都相当于是令发送DMRS的comb与发送所述上行控制信息的comb一致，即，宗旨都是使得DMRS与所述上行控制信息在资源单元集合中占用相同的频域子载波，从而可以使得一个终端设备在资源单元集合中发送的DMRS与其他终端设备在该资源单元集合中发送的上行控制信息可以实现频域正交，减少冲突。
4、信令确定方式。
例如，网络设备可以向终端设备发送高层信令或动态信令，该高层信令或动态信令用于指示DMRS所占用的所述部分频域子载波，例如指示所述部分频域子载波的索引。则终端设备接收高层信令或动态信令后，就可以确定通过该物理上行控制信道所发送的DMRS所占用的所述部分频域子载波。
其中，高层信令例如为RRC信令，动态信令例如为通过物理下行控制信道承载的信令，例如为DCI。
在这种方式下，DMRS所占用的RE的索引是由网络设备半静态指示的，该信令存在一定的生效周期，可以减少信令的开销。
如上介绍的4种确定方式中，直接确定方式、物理上行控制信道确定方式、以及信令确定方式，都可以认为是基于如前的子载波原则的确定方式，而正交码确定方式可以认为是基于如前的正交码原则的确定方式。或者，因为无论是子载波原则还是正交码原则，其实质都是要使得所述部分频域子载波与所述上行控制信息所占用的频域子载波相同，因此，如上介绍的4种确定方式，即直接确定方式、正交码确定方式、物理上行控制信道确定方式、以及信令确定方式，都可以认为是基于如前的子载波原则的确定方式。
下面介绍终端设备生成物理上行控制信道的方法，或者说，介绍终端设备生成承载在物理上行控制信道上的所述上行控制信息和所述解调参考信号的方法，以下分别介绍。
A、上行控制信息。
终端设备根据待传输的上行控制信息的比特数，以及所述物理上行控制信道所能承载的编码后比特数量，通过信道编码生成编码后比特。例如，待传输的上行控制信息包括20比特，所述物理上行控制信道所能承载的编码后比特数量为120比特，则终端设备采用极化码(polar code)的编码方式，将20比特信息编码为120比特信息。
终端设备将生成的编码后比特信息进行分组，每组编码后比特信息对应1个时域符号，终端设备将每组编码后比特信息进行DFT变换后，映射在频域子载波上。
例如，当comb为2时，编码后比特为120比特，上行控制信息占用10个时域符号，则每个时域符号上承载12比特的编码后比特，即6个正交相移键控(quadrature phase shift keying，QPSK)符号(a0,a1,a2,a3,a4,a5)，终端设备将OCC(1,1,1,1,1,1,1,1,1,1,1,1)加扰到6个QPSK符号上，生成12个加扰后的QPSK符号(a0,a1,a2,a3,a4,a5,a0,a1,a2,a3,a4,a5)，然后终端设备对(a0,a1,a2,a3,a4,a5,a0,a1,a2,a3,a4,a5)进行12点的DFT变换，生成待传输 的上行控制信息(a0',0,a1',0,a2',0,a3',0,a4',0,a5',0)，终端设备将待传输的上行控制信息(a0',0,a1',0,a2',0,a3',0,a4',0,a5',0)连续地映射到资源单元集合的12个子载波上。
或者，当comb为2时，编码后比特为120比特，上行控制信息占用10个时域符号，则每个时域符号上承载12比特的编码后比特，即6个QPSK符号(a0,a1,a2,a3,a4,a5)，终端设备对(a0,a1,a2,a3,a4,a5)进行6点的DFT变换后，生成待传输的上行控制信息(a0'’,a1'’,a2'’,a3'’,a4'’,a5'’)，终端设备将待传输的上行控制信息(a0'’,a1'’,a2'’,a3'’,a4'’,a5'’)等间隔地映射在资源单元集合的奇数频域子载波或者偶数频域子载波上。
B、解调参考信号。
例如当comb为2时，DMRS的序列长度为6，终端设备将长度为6的DMRS序列直接映射在DMRS对应的所述部分频域子载波上，所述部分频域子载波是根据前文所介绍的方法确定的，例如所述部分频域子载波的索引为{0,2,4,6,8,10}。
S64、终端设备发送该物理上行控制信道，则网络设备接收该物理上行控制信道。网络设备从该物理上行控制信道获得所述解调参考信号和所述上行控制信息。
终端设备生成所述物理上行控制信道后，即可发送所述物理上行控制信道。对于网络设备来说，也可以按照与终端设备相同的方式确定该物理上行控制信道的DMRS所占用的所述部分频域子载波，从而在接收该物理上行控制信道后，可以根据所述部分频域子载波获得DMRS。因为网络设备确定所述部分频域子载波的方式可与终端设备相同，因此不多赘述。
可参考图7C，为采用本申请实施例提供的技术方案后，两个终端设备在一个资源单元集合内进行复用的示意图，其中终端设备a使用长为7个符号的long PUCCH，图7C中的a0',a1',a2',a3',a4',a5'表示终端设备a发送的上行控制信息，终端设备b使用长为5个符号的long PUCCH，图7C中的b0',b1',b2',b3',b4',b5'表示终端设备b发送的上行控制信息，DMRS(a)表示终端设备a发送的DMRS，DMRS(b)表示终端设备b发送的DMRS。可以看到，不同长度的long PUCCH的DMRS与上行控制信息在同一OFDM/DFT-s-OFDM符号上可以复用，且在不同长度的long PUCCH的DMRS与上行控制信息在同一OFDM/DFT-s-OFDM符号上复用时，DMRS与UCI占用的是不同的频域资源，从而保证不同长度的long PUCCH的DMRS符号不对齐时，也可以实现灵活的复用，同时可以保证了在1个long PUCCH中能够包含充足数量的DMRS。
本申请实施例中，多个不同长度的long PUCCH在1个资源单元集合内复用时，DMRS的位置可以随long PUCCH的长度变化而灵活地设计，从而可以尽量保证信道估计的性能。
