技术领域
本申请涉及通信技术领域，尤其涉及一种探测参考信号生成方法及装置。
背景技术
在时分双工(time division duplex，TDD)场景中，网络设备可以测量用户设备(user equipment，UE)发送的探测参考信号(sounding reference signal，SRS)，得到上行信道信息，并基于上行信道和上下行信道的互易性，来推断出下行信道的信道状态信息(channel state information，CSI)。在第三代合作伙伴计划(3rd-generation partnership project，3GPP)标准版本18(Release，R18)中，引入了相干联合传输(coherent joint transmission，CJT)，其最多可以支持4个网络设备同时为UE进行下行传输。随着CJT的引入，更多的传输接收点(transmission reception point，TRP)需要通过SRS来进行信道估计，因此SRS的需求会大大增加。这会引入更多的SRS之间的干扰。SRS之间的干扰会直接影响网络设备的信道估计。因此，如何降低SRS之间的干扰是目前亟待解决的技术问题。

其次，对本申请涉及的相关名称或术语进行阐述，以便于本领域技术人员理解。
1、重复因子
在本申请中，重复因子(repetition factor，R)用于描述SRS时域符号的传输单位，即在时域上以几个SRS符号作为传输单位进行传输。例如重复因子为4，表示以4个SRS符号作为传输单位进行传输。再例如，重复因子为2，表示以2个SRS符号作为传输单位进行传输。重复因子可以理解为符号级别的重复参数。需要说明的是，重复因子这个名称用于举例，其他用于描述重复因子本质的名称可以与重复因子替换。
重复因子通常与SRS资源的时域符号数一起配置，SRS资源的时域符号数表示一个SRS资源在时域上占用的符号数。重复因子与SRS资源的时域符号数可由高层参数resourceMapping配置，例如高层参数resourceMapping的配置可包括：
SRS资源的时域符号数可表示为N_symbol，重复因子可表示为R。例如，R17支持(N_symbol，R)＝{(8,1)，(8,2)，(8,4)，(8,8)，(12,1)，(12,2)，(12,4)，(12,6)，(12,12)，(10,1)，(10,2)，(10,5)，(10,10)，(14,1)，(14,2)，(14,7)，(14,14)}。
示例性的，(N_symbol，R)＝(8,2)，其中，8表示一个SRS资源在时域上占用8个符号；2表示每2个符号作为一个整体传输，例如每2个符号作为一个整体进行跳频；那么 这8个符号可分为2个符号*4，即4个传输，每个传输用于传输2个符号。这8个符号中每个符号承载的SRS信息相同。
示例性的，(N_symbol，R)＝(12,1)，其中，12表示一个SRS资源在时域上占用12个符号；1表示每个符号作为一个整体传输，例如每1个符号作为一个整体进行跳频；那么这12个符号可分为1个符号*12，即12个传输，每个传输用于传输1个符号。这12个符号中每个符号承载的SRS信息相同。
目前，SRS资源的时域符号数的取值范围可以是{1,2,4,8,10,12,14}，R的取值范围可以是{1,2,4,5,6,7,8,10,12,14}。需要说明的是，本申请涉及的符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，离散傅里叶变换扩频OFDM(Discrete Fourier Transform-spread OFDM)符号，或者其他符号，本申请不作限定。
2、TD-OCC序列
TD-OCC序列指的是时域上的OCC序列。TD-OCC序列也可以描述为时域OCC序列。
在一种实现方式中，TD-OCC序列可以用于生成物理上行控制信道(physical uplink control channel，PUCCH)。
例如对于PUCCH格式(format)2而言，用于生成PUCCH的TD-OCC序列可如下表1或表2所示。
表1：时，针对PUCCH format2的正交序列wn(i)
表2：时，针对PUCCH format2的正交序列wn(i)
其中，n表示正交序列索引，wn(i)表示正交序列索引对应的TD-OCC序列，i表示正交序列索引中第i个元素。表示PUCCH format2在一个子帧(subframe，SF)中占用2个符号，其对应的TD-OCC序列可以是[+1+1]或[+1-1]。表示PUCCH format2在一个子帧SF中占用4个符号，其对应的TD-OCC序列可以是[+1+1+1+1]或[+1-1+1-1]或[+1+1-1-1]或[+1-1-1+1]。
再例如，对于PUCCH format4和交织映射的PUCCH format3而言，用于生成PUCCH的TD-OCC序列可如下表3或表4所示。
表3：时，针对PUCCH format4和交织映射的PUCCH format3的正交序列wn(i)
表4：时，针对PUCCH format4和交织映射的PUCCH format3的正交序列wn(i)
其中，表示PUCCH format4或交织映射的PUCCH format3在一个SF中占用2个符号，其对应的TD-OCC序列可以是[+1+1]或[+1-1]。表示PUCCH format4或交织映射的PUCCH format3在一个子帧SF中占用4个符号，其对应的TD-OCC序列可以是[+1+1+1+1]或[+1-j+1+j]或[+1-1+1-1]或[+1+j-1-j]。
在另一种实现方式中，TD-OCC序列可以用于生成物理上行共享信道(physical uplink shared channel，PUSCH)调制解调参考信号(demodulation reference signal，DM-RS)。例如，用于生成PUSCH DM-RS的TD-OCC序列可如下表5所示。
表5：针对PUSCH DM-RS类型1的参数
其中，wf(k')表示频域OCC序列，wt(l')表示TD-OCC序列。CDM表示码分复用(code division multiplexing)，CDM组的索引用λ表示。
在又一种实现方式中，TD-OCC序列可以用于生成物理下行共享信道(physical downlink shared channel，PDSCH)DM-RS。例如，用于生成PDSCH DM-RS的TD-OCC序列可如下表6所示。
表6：针对PDSCH DM-RS类型1的参数

其中，wf(k')表示频域OCC序列，wt(l')表示TD-OCC序列。
在又一种实现方式中，TD-OCC序列可以用于信道状态信息参考信号(channel state information-reference signal，CSI-RS)。例如，对于CDM类型为CDM4(FD2,TD2)而言，用于生成CSI-RS的TD-OCC序列可如下表7所示；对于CDM类型为CDM8(FD2,TD4)而言，用于生成CSI-RS的TD-OCC序列可如下表8所示。
表7：CDM4(FD2,TD2)的频域序列wf(k')和时域序列wt(l')
表8：CDM4(FD2,TD4)的频域序列wf(k')和时域序列wt(l')
示例性的，可参见图2所示的用于生成CSI-RS的OCC序列的示例图。图2以CDM4(FD2，TD2)为例，表示在频域占用2个资源单元(resource element，RE)，在时域占用2个符号。天线端口3000至天线端口3003这四个天线端口占用相同的时频资源。这四个天线端口上传输的CSI-RS通过乘以不同的OCC序列，以实现CSI-RS之间的正交性，实现同一时频资源传输4个CSI-RS，这4个CSI-RS的基序列可以相同或不同。采用不同的OCC序列在同一时频资源上生成不同的CSI-RS，可提升***容量。需要说明的是，图2 中的OCC序列由频域OCC序列和时频OCC序列组成。
为了降低SRS之间的干扰，可通过提升SRS之间的正交性实现。提升SRS之间的正交性，可通过TD-OCC序列生成SRS实现。因此，本申请提供一种SRS生成方法及装置，可以降低SRS之间的干扰，从而有利于网络设备进行信道估计。
下面对本申请提供的SRS生成方法进行阐述。
请参见图3，是本申请提供的SRS生成方法的流程示意图，该流程具体包括以下步骤：
S301，网络设备向终端设备发送第一配置信息。相应的，终端设备接收来自网络设备的第一配置信息。
其中，第一配置信息用于配置SRS在时域上的重复因子，重复因子的取值为大于或者等于1的正整数。本申请可以适应于重复因子的取值大于1的情况。其中，重复因子的取值为预设取值集合中的一个。预设取值范围可以由协议预定义。例如，预设取值集合{1,2,4,5,6,7,8,10,12,14}，随着标准的演进，预设取值集合可能会发生变化(如增加某些取值或减少某些取值)。为了描述方便，下文将重复因子简称为R。
可选的，第一配置信息还可以包含SRS资源所采用的TD-OCC信息。其中，所述TD-OCC信息可以包含一个或者多个TD-OCC序列索引号，或者所述TD-OCC信息用于配置TD-OCC序列的长度信息，或者所述TD-OCC信息用于配置TD-OCC序列的生成信息。
可选的，第一配置信息还可以包含SRS的TD-OCC功能的激活和/或去激活指示信息。其中，当SRS的TD-OCC功能激活时，R可以同时关联有TD-OCC信息。即，第一配置信息配置了R的同时，也可以隐式的找到R关联的TD-OCC信息。其中，所述TD-OCC信息可以包含有一个或者多个OCC序列索引号，或者所述TD-OCC信息用于配置TD-OCC序列的长度信息，或者所述TD-OCC信息用于配置TD-OCC序列的生成信息。其中，终端设备也可以向网络设备汇报自己是否支持SRS的TD-OCC能力。终端设备支持SRS的TD-OCC能力，表明终端设备可以生成和/或使用SRS的TD-OCC序列，那么第一配置信息可以包含或隐式指示所述TD-OCC信息。终端设备不支持SRS的TD-OCC能力，表明终端设备不能生成和/或使用SRS的TD-OCC序列，那么第一配置信息不包含或不隐式指示所述TD-OCC信息。
可选的，第一配置信息还可以包含指示信息，用于指示终端设备激活或去激活第一能力，第一能力指的是不同序列长度的TD-OCC在1个SRS资源内部能够同时使用。换言之，第一能力指的是在1个SRS资源内部能同时使用不同序列长度的TD-OCC序列。其中，终端设备也可以向网络设备汇报自己是否支持所述第一能力。
第一配置信息可以是无线资源控制(radio resource control，RRC)信令。
S302，终端设备确定与重复因子匹配的TD-OCC序列，该TD-OCC序列的序列长度小于或等于重复因子的取值。
终端设备可采用如下方式1或方式2或方式3，确定与R匹配的TD-OCC序列，该TD-OCC序列的序列长度小于或等于R的取值。
本申请中提到的SRS符号指的是用于传输SRS的符号，其中符号可以是OFDM符号，DFT-s-OFDM符号，或者其他符号，本申请不做限制。

可选的，以公式的方式来描述，以与R匹配的TD-OCC序列的序列长度为M时，R除以M的商记为X，余数记为Y。那么，表示，R个SRS符号中有个X组M个SRS符号各自乘以或者关联序列长度为M的TD-OCC序列，还有Y个SRS符号可以不进行TD-OCC的操作。中，X组M个SRS符号所采用的TD-OCC序列可以一样。可选的，所述Y个SRS符号可以是R个SRS符号从时间上最后面的Y个SRS符号或者是R个SRS符号从时间上 最前面的Y个SRS符号。
可选的，以公式的方式来描述，以与R匹配的TD-OCC序列的序列长度为M和N时(M>N)，R除以M的商记为X1，余数记为Y1,Y1除以N的商记为X3，余数记为Y2,那么，表示，R个SRS符号中有个X1组M个SRS符号各自乘以或者关联序列长度为M的TD-OCC序列，还有X3组N个SRS符号各自乘以或者关联序列长度为N的TD-OCC序列，可选的，还可以有Y2个SRS符号不乘以TD-OCC序列。其中，X1组M个SRS符号所采用的TD-OCC序列可以一样，和/或X3组N个SRS符号所采用的TD-OCC序列也可以一样。可选的，所述Y2个SRS符号可以是R个SRS符号从时间上最后面的Y2个SRS符号或者是R个SRS符号从时间上最前面的Y2个SRS符号。其中，从时间上来看，X1组M个SRS符号可以在X3组N个SRS符号之前或者之后。

进一步的，对于上述方式2，网络设备还可向终端设备发送第二修改命令，相应的，终端设备接收来自网络设备的第二修改命令。其中，第二修改命令用于指示修改上述一个或多个参考TD-OCC序列。例如，R＝6，第二配置信息指示两个TD-OCC序列，分别为[+1+1]和[+1+1-1-1]，第二修改命令可指示将[+1+1]修改为[+1-1]，从而与R匹配的TD-OCC序列可表示为[+1-1+1+1-1-1]。第二修改命令例如可以是MAC-CE。通过第二修改命令修改第二配置信息指示的参考TD-OCC序列，有助于提高灵活性。

对于R＝5：与R匹配的TD-OCC序列可以是协议预定义的序列长度为5的TD-OCC序列； 也可以是协议预定义的序列长度为4的TD-OCC序列(有利于扩容)。
对于R＝6：与R匹配的TD-OCC序列可以是协议预定义的序列长度为6的TD-OCC序列；
也可以是协议预定义的序列长度为5的TD-OCC序列(有利于扩容)；也可以是协议预定义的1个序列长度为4的TD-OCC序列与1个序列长度为2的TD-OCC序列的组合；还可以是协议预定义的3个序列长度为2的TD-OCC序列的组合。
对于R＝7：与R匹配的TD-OCC序列可以是协议预定义的序列长度为7的TD-OCC序列；
也可以是协议预定义的序列长度为6的TD-OCC序列(有利于扩容)。
对于R＝8：与R匹配的TD-OCC序列可以是协议预定义的序列长度为8的TD-OCC序列；也可以是协议预定义的序列长度为7的TD-OCC序列(有利于扩容)；也可以是协议预定义的4个序列长度为2的TD-OCC序列的组合；也可以是2个序列长度为4的TD-OCC序列的组合；也可以是1个序列长度为4的TD-OCC序列与2个序列长度为2的TD-OCC序列的组合。
对于R＝10：与R匹配的TD-OCC序列可以是协议预定义的序列长度为10的TD-OCC序列；也可以是协议预定义的5个序列长度为2的TD-OCC序列的组合；也可以是4个序列长度为2的TD-OCC序列和1个序列长度为2的TD-OCC序列的组合；也可以是3个序列长度为2的TD-OCC序列与1个序列长度为4的TD-OCC序列的组合。
对于R＝12：与R匹配的TD-OCC序列可以是协议预定义的序列长度为12的TD-OCC序列；也可以是协议预定义的6个序列长度为2的TD-OCC序列的组合；也可以是2个序列长度为4的TD-OCC序列和2个序列长度为2的TD-OCC序列的组合；也可以是3个序列长度为4的TD-OCC序列的组合。
对于R＝14：与R匹配的TD-OCC序列可以是协议预定义的序列长度为14的TD-OCC序列；也可以是协议预定义的7个序列长度为2的TD-OCC序列的组合；也可以是2个序列长度为4的TD-OCC序列和3个序列长度为2的TD-OCC序列的组合；也可以是5个序列长度为2的TD-OCC序列和1个序列长度为4的TD-OCC序列的组合；还可以是1个序列长度为2的TD-OCC序列和3个序列长度为4的TD-OCC序列的组合。
上述方式1至方式3可以择一执行，也可以结合执行，例如结合方式2和方式3，第二配置信息用于指示预定义的多个TD-OCC序列中的至少一个TD-OCC序列。需要说明的是，上述方式1至方式3用于举例，并不构成对本申请的限定。
S303，终端设备基于该TD-OCC序列，生成SRS。
可选的，终端设备基于该TD-OCC序列和SRS基序列生成SRS。例如，该TD-OCC序列与SRS基序列相乘，可得到SRS序列，基于该SRS序列可得SRS。SRS基序列可能以R为传输单位，也可能不以R为传输单位。若以R为传输单位，那么该TD-OCC序列与SRS基序列的序列长度相同。若不以R为传输单位，那么从SRS基序列中选择与该TD-OCC序列对应的基序列，将该基序列与该TD-OCC序列相乘可得SRS序列。也就是说，生成的SRS指的是一个传输单位R的SRS。例如，R＝4，生成的SRS指的是在时域上，一个以4个符号为传输单位的SRS。再例如，R＝6，生成的SRS指的是在时域上，一个以6 个符号为传输单位的SRS。
示例性的，R＝6，基于TD-OCC序列1生成SRS1，基于TD-OCC序列2生成SRS2，TD-OCC序列3生成SRS3，TD-OCC序列4生成SRS4，这4个TD-OCC序列的序列长度为6，这4个SRS在时域上占用相同的6个符号。由于这4个TD-OCC序列具有正交性，使得这4个SRS之间的干扰较小，从而这6个符号上可承载4个终端设备的SRS或承载1个终端设备的4个SRS，从而有利于提升***容量。
在图3所示的实施例中，基于重复因子生成TD-OCC序列，基于TD-OCC序列生成SRS，可以降低SRS之间的干扰，从而有利于网络设备进行信道估计。基于TD-OCC序列生成SRS，还可以提升***容量。
作为一种可选的实施例，网络设备针对某些R可能不会配置TD-OCC序列，或协议针对某些不会预定义TD-OCC序列，例如针对R＝5或R＝7不会配置TD-OCC序列，那么便不能应用本申请提供的方法，或者采用跳频方法以减少SRS之间的干扰。或者，跳频方法与本申请提供的方法是排他关系。
作为一种可选的实施例，生成的SRS是一个以R为传输单位的SRS，TD-OCC序列所对应的SRS符号不会横跨两个相邻的R个SRS符号。即每R个SRS符号的起始符号都是一个新的TD-OCC序列的起始。例如(12,6)，每6个SRS符号的起始符号都是一个新的TD-OCC序列的起始。
作为一种可选的实施例，生成的SRS的时域资源与物理上行信道的时域资源均包括第一时域资源，那么丢弃SRS的时域资源并在物理上行信道的时域资源上发送物理上行信道。其中，物理上行信道可以是物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)。SRS的时域资源与物理上行信道的时域资源均包括第一时域资源，可以理解为SRS的时域资源与物理上行信道的时域资源占用相同的时域资源，或SRS与物理上行信道在时域上发生碰撞。丢弃SRS的时域资源可以理解为丢弃整个SRS资源，也就是说不发送SRS。
在另一种实现方式中，生成SRS的时域资源与物理上行信道的时域资源均包括第一时域资源时，确定第一时域资源对应的冲突的SRS TD-OCC序列，丢弃掉冲突的SRS TD-OCC序列所对应的SRS符号。例如，R＝6，与R匹配的TD-OCC序列由一个序列长度为2的TD-OCC序列和一个序列长度为4的TD-OCC序列组成，若第一时域资源对应的冲突TD-OCC序列为序列长度为2的TD-OCC序列，那么将该序列长度为2的TD-OCC序列所对应的SRS符号丢弃，保留该序列长度为4的TD-OCC序列所对应的SRS符号，从而使得SRS仍然可以传输；若第一时域资源对应的冲突TD-OCC序列为这2个TD-OCC序列，那么可丢弃这2个TD-OCC序列，不传输SRS或传输的SRS不采用TD-OCC序列。再例如，与R匹配的TD-OCC序列是一个预定义的序列长度为6的TD-OCC序列，若第一时域资源对应的冲突TD-OCC序列为该序列长度为6的TD-OCC序列，那么丢弃这个序列长度为6的TD-OCC序列，不传输SRS或传输的SRS不采用TD-OCC序列。从而可以避免时域冲突。SRS的时域资源与物理上行信道的时域资源均包括第一时域资源，可以理解为SRS的时域资源与物理上行信道的时域资源占用相同的时域资源，或SRS与物理上行信道在时域上发生碰撞。丢弃SRS的时域资源可以理解为丢弃整个SRS资源，也就是说不发送SRS。 其中，物理上行信道可以是物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)。
