在接收第一信息之前或者之后，由UE或定位管理功能实体(Location Management Function,LMF)发送第二消息至网络侧设备或者服务小区设备。
所述第二信息用于确定以下至少一种：第二小区，第二小区用于指示所述终端期 待的用于发送目标SRS的第一小区；第二小区组，用于指示所述终端期待的用于发送目标SRS的第一小区组，所述第二小区组是对所述第二小区进行分组得到的，各所述第二小区组中至少包括2个第二小区；第二聚合带宽；终端是否进行聚合；聚合发送的SRS所属的带宽；聚合发送的SRS所属的频点信息；所述目标SRS的配置信息；预配置SRS的配置信息。
第二小区可以为倾向进行SRS聚合的小区，其可以指示聚合小区的数目或聚合小区识别信息。类似的，第二小区组为倾向进行SRS聚合的小区组，其可以指示该小区组的识别信息。第二聚合带宽，为进行SRS聚合时，倾向使用的带宽。可选的，第二聚合带宽例如大于一个载波或者小区的带宽。聚合发送的SRS所属的频点信息可以包括绝对信道号(Absolute Radio-Frequency Channel Number，ARFCN)、参考点A、起始PRB、载波偏移、载波中心信息，子载波间隔。

可选的，多个小区同时发送的目标SRS具备相同的空间关系，即SRS的空间关系信息。例如，可以关联相同的空间关系参考信号，使目标SRS具有相同的空间关系。多个小区同时发送的目标SRS具备相同的路损参考信号。路损参考信号相同的功率调整系数例如为po或者alpha。时域起始位置例如为时隙，符号起始位置等。
S402:在N个第一小区上以聚合方式发送M个目标探测参考信号SRS。
本步骤采用图2或图3实施例对应步骤的描述，在此不再赘述。
本申请实施例提供的处理探测参考信号的方法，通过发送第二信息，可以反馈倾向进行聚合的第二小区以及第二小区组的相关信息，促进SRS聚合。
在另一个实施例中，所述目标SRS还满足至少一个以下特征：所述多个第一小区发送所述目标SRS的频域间隔为梳状(comb)值与子载波间隔乘积的整数倍；所述多个第一小区发送的所述目标SRS的参考点A不同；所述多个第一小区发送的所述目标SRS形成目标区域码(Zone Code，ZC)序列。
当前SRS是各小区下的配置。SRS需要满足一定的限定条件，才能使得SRS在多小区聚合时获得增益。例如SRS comb值相同，SRS子载波间隔与PRS comb值的乘积相同，循环前缀类型相同，参考点A相同，每个小区中包含相同的SRS资源或SRS集。可选的，多个小区的参考点A相同。
多个第一小区发送所述目标SRS的频域间隔为例如小区1上最后一个发送SRS的RE和小区2上第一个发送SRS的RE之间的间隔。在所述频域间隔不是物理资源块PRB的整数倍，或所述频域间隔不是comb与子载波间隔乘积的整数倍的情况下，所述目标SRS在不同第一小区的RE位移不同。在一种实现方式中，通过增强协议约束等，可以保证上述条件生成。在另一种实现方式中，网络侧设备在N个小区上指示不同小区的RE位移以满足梳状comb值与子载波间隔乘积的整数倍；在又一种实现方式中，网络侧设备在N个小区上配置相对于参考小区的RE位移的偏移以满足梳状comb值与子载波间隔乘积的整数倍。
可选的，在另一种实施例中，网络侧设备在N个小区关联的point A不同，以使得相同的RE offset也可以保证发送目标SRS的多个第一小区发送所述目标SRS的频域间隔为comb与子载波间隔乘积的整数倍。
不同小区(载波)上的频域起始位置不同，可以通过如下公式确定第一小区上的频域起始位置，即不同小区上的频域起始位置是根据各个小区自己的参数计算的：
其中，

用于表示参考点，用于表示相对于参考点的频域偏移，用于表示SRS的comb位移，用于表示符号l′取值不大于comb值的RE位移，用于表示SRS的天线端口数，用于表示SRS的最大的循环位移，用于表示SRS在第一个符号上的资源单元偏移RE offset位移，用于表示资源块RB的子载波数目，用于表示SRS的跳频偏移；用于表示RB的子载波数目，其中载波i表示为小区i。
上述可以理解为，第一个符号的RE offset在不同的小区上不同，以保证发送目标SRS的多个第一小区发送所述目标SRS的频域间隔为comb与子载波间隔乘积的整数倍。
小区i相对于参考小区的RE位移的偏移；
参见图5示出的载波聚合结构示意图，通过配置使得频域间隔满足上述条件。
例如在一种情况下，子载波间隔为30k，两个小区之前存在的载波间隔GP为1.98M，即66个子载波，载波间隔为5个PRB+6个子载波，不是PRB的整数倍。
假设，小区1包含0-215PRB(38.88M)，小区2和小区1间隔68个子载波(即5个PRB+8个子载波)。结合下表1：
表1
小区1的RE 1和RE5，RE 9对应的Comb offset＝1。小区2的RE1对应小区1的6+RE1＝RE7，小区2的RE5和RE9分别对应小区1的RE11和RE3，其comb offset＝3。即相同的RE位移无法获得实际相同的RE offset。
公共资源块(Common Resource Block,CRB)的频域位置为：
是参考点，如CRB＝0，或者BWP的最低频率位置。nshift为相对于参考点的RB偏移，由高层参数freqDomainShift配置，取值为0～268PRB。 为SRS resource的comb位移。为per符号的RE位移。取值不能大于comb值。
SRS的位移值满足下表2中KTC和l′的函数关系。
表2
所述目标ZC序列N个小区上的序列为一个ZC序列，所述序列的带宽根据N个小区上用于发送SRS的合带宽计算。
满足:

其中，用于表示所述目标ZC序列的长度，用于表示所述第一小区的ZC序列的长度，mSRS,b用于表示单位为PRB的一跳(hop)的带宽，用于表示子载波数，KTC用于表示comb值，PF用于表示频率调整因子。
本申请实施例提供的处理探测参考信号的方法，通过目标SRS还满足至少一个以下特征：所述多个第一小区发送所述目标SRS的频域间隔为梳状(comb)值与子载波间隔乘积的整数倍；所述多个第一小区发送的所述目标SRS的参考点A不同；所述多个第一小区发送的所述目标SRS形成目标ZC序列，能够使SRS满足一定的限定条件，进而在多小区聚合时获得增益。
如图6所示，本申请的一个实施例提供一种处理探测参考信号的方法，该方法可以由终端设备和/或网络设备执行，换言之，该方法可以由安装在终端设备和/或网络设备的软件或硬件来执行，该方法包括如下步骤：
