下文中将参考附图并结合实施例来详细说明本公开。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
本申请实施例可以运行于图1所示的网络架构上，图1是本公开实施例的网络构架图，如图1所示，该网络架构包括：第一通信节点、第二通信节点，其中，第一通信节点向第二通信节点发送上行信号。
第一通信节点可以为宏小区的基站、小小区(small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点等节点，第二通信节点可以为用户终端(UE)、手机、便携设备、汽车等通信系统中的节点。
在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载下行控制信息(Downlink Control Information，简称为DCI)，其中，DCI可包括上、下行调度信息，以及上行功率控制信息。DCI格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。第一通信节点，例如演进型基站(e-Node-B，简称为eNB)可以通过下行控制信息配置第二通信节点设备，例如用户设备(User Equipment，简称为 UE)，或者第二通信节点设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE。
测量参考信号(Sounding Reference Signal，简称为SRS)是一种第二通信节点设备与第一通信节点间用来测量无线信道信息(Channel State Information，简称为CSI)的信号。在长期演进系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
在LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即：天线专有的SRS，而对物理上行共享信道(Physical Uplink Shared Channel,简称为PUSCH)的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。第一通信节点通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点估计出上行原始的CSI。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，目前的研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。
上行信号可以为SRS，或者为上行解调参考信号，或者为进行随机接入的上行信号，或者为PUSCH信号，或者为相位跟踪参考信号。
天线端口也可被称为发送端口或者上行信号的端口。

步骤S302，第一通信节点通过物理下行控制信令或高层信令向第二通信节点发送配置信息，第一通信节点接收第二通信节点基于配置信息发送的上行信号；或者，第一通信节点根据与第二通信节点约定的规则，接收第二通信节点发送的上行信号。

通过上述步骤，确定不同上行信号的发送天线，上行信号之间采用不同的天线发送时，在第一上行信号与第二上行信号之间预留保护间隔，保证了用户设备能在时域上顺利切换上行信号，解决了相关技术中不能在时域顺利切换不同天线发送的不同上行信号的技术问题。

实施例3
本实施例是本申请的可选实施例，包括多个实施方式，用于对本申请的方案进行详细和补充说明：
实施方式一
通过SRS的天线切换，可以解决第二通信节点的发送链路数与接收链路数不一致时的信道互易问题，如第二通信节点配置为1T2R、2T4R、4T8R的情况。其中，T表示发送链路数，R表示接收链路数，例如1T2R表示发送链路数为1，接收链路数为2。
对于1T2R的SRS天线(Antenna)切换，图6是本公开实施方式一中使用一个slot(时隙)发送SRS和PUSCH/PUCCH的示意图，如图6所示，如果在发送SRS的第一个时域符号所使用的天线与前面符号发送PUSCH/PUCCH所使用的天线一致，则SRS与PUSCH/PUCCH之间不需要预留时域保护间隔；如果在发送SRS的第一个时域符号所使用的天线与前面符号发送PUSCH/PUCCH所使用的天线不一致，则SRS与PUSCH/PUCCH之间需要预留时域保护间隔。
实施方式二
对于1T4R的非周期SRS天线切换，基站需要为UE配置4个SRS资源，每个SRS资源占用1个时域符号，由于目前协议只支持每个时隙里面最多配置6个符号用于SRS发送，因此至少需要两个时隙才能完成SRS的4天线切换。如图7所示，图7是本公开实施方式二中使用两个slot发送SRS和PUSCH/PUCCH的示意图，在时隙1上，在第一个发送SRS的符号上采用与PUSCH/PUCCH一样的天线发送SRS，则第一个时隙的PUSCH/PUCCH与SRS之间不用预留时域保护间隔；在时隙2上，如果发送PUSCH/PUCCH的天线与时隙2中相邻的SRS所在符号所使用的天线不一致，则需要预留Y个符号的保护间隔，Y的取值与UE所使用的子载波间隔有关。表1用于表示子载波间隔与Y的对应关系。
表1
μ Δf＝2 μ·15[kHz] Y[符号]
0 15 1
1 30 1
2 60 1
3 120 2
实施方式三
对于1T4R的非周期SRS天线切换，如果发送PUSCH/PUCCH的天线与当前时隙中相邻的SRS所在符号所使用的天线不一致，则UE根据PUSCH/PUCCH的码率或MCS索引或调制阶数决定是否打掉Y个时域符号的PUSCH/PUCCH，这Y个符号当成保护间隔使用。例如，当MCS索引小于或等于5时，则UE打掉Y个时域符号的PUSCH/PUCCH；当MCS索引大于5时，则UE不会打掉Y个时域符号的PUSCH/PUCCH，而是在PUSCH/PUCCH相邻的时域符号上不发送SRS。
实施方式四
对于1T4R的非周期SRS天线切换，UE自行决定是否打掉Y个时域符号的PUSCH/PUCCH或者在PUSCH/PUCCH相邻的时域符号上不发送SRS，基站通过盲检测得到PUSCH/PUCCH与SRS之间是否有保护间隔的信息。
实施方式五
对于1T4R的非周期SRS的天线切换，时隙之间SRS资源的分配方式(分配在时隙1上的SRS资源数量+分配在时隙2上的SRS资源数量)可以有如下的形式：2+2；3+1；1+3。
对于2+2这种资源分配方式，标准协议化比较简单，但SRS资源利用效率不高，而3+1和1+3这种方式，则可以基于slot内的SRS可用资源大小，充分地利用SRS资源。
为了支持这3种方式，UE可以根据基站配置的时隙偏置(slot offset)数量来决定采用哪种方式。如果RRC配置的slot offset数量为1，UE则采用3+1或1+3这种资源自适应的方式；如果RRC配置的slot offset数量为2，UE则固定采用2+2这种简单的资源配置方式。
实施方式六
为了让测量SRS得到的信道信息快速地应用到后面的调度中，可以将SRS在时域符号位置配置在上行DMRS所在位置之前，或者配置在下行控制与PUSCH或上行DMRS之间的保护间隔上。如图8所示，图8是本公开实施方式六中SRS的时域位置示意图。
当SRS1与上行DMRS所使用的发送天线不一致时，则SRS1与上行DMRS之间需要预留Y个符号的保护间隔；
SRS1和SRS2属于相同的SRS资源集(SRS resource set)中的不同资源，或者SRS1和SRS2分别属于不同的SRS资源集。
UE上报处理速度相关的能力，基站根据能力和配置的保护间隔大小决定是否在当前时隙触发SRS1。
