2)网络设备，又称为无线接入网(radio access network，RAN)设备是一种将终端设备通过授权频谱和非授权频谱接入到无线网络的设备，其包括各种通信制式中的网络设备，例如包括但不限于：无线接入点(例如无线局域网接入点)，基站、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、网络设备控制器(base station controller，BSC)、网络设备收发台(base transceiver station,BTS)、家庭网络设备(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)等。

需要指出的是，本申请实施例中涉及的名词或术语可以相互参考，不再赘述。
在长期演进(long term evolution，LTE)系统或长期演进技术升级版(LTE-advanced，LTE-A)系统中，网络设备可以向网络设备发送下行控制信息，下行控制信息指示终端设备向网络设备发送SRS，其中，SRS用于上行信道的测量，并且当上行信道与下行信道之间具有互易性的时候，SRS还可以用于获取下行信道状态信息。在LTE/LTE-A系统中，SRS具有两种类型，这两种类别分别非周期SRS和周期性SRS。
在网络设备指示终端设备向网络设备发送的非周期SRS的时候，会出现不需要终端设备而向网络设备传输数据的情况，即这个时候，网络设备需要测量信道，但是不需要终端设备向网络设备调度传输块(transport block，TB)。
为了避免不必要的数据传输，在LTE/LTE-A系统中，提供了一种终端设备向网络设备发送SRS，但是网络设备不调度传输块或资源的方法，该方法为disable TB方法。disable TB方法的具体过程为：网络设备向终端设备发送下行控制信息，其中，下行控制信息中的MCS的索引值为0，且下行控制信息中的RV的索引值为1；终端设备在接收到下行控制信息之后，终端设备读取下行控制信息中的MCS的索引值和RV的索引值；终端设备在确定MCS的索引值为0，且RV的索引值为1的时候，终端设备就向网络设备发送SRS，但是终端设备不去调度传输块，进而终端设备不向网络设备传输数据。从而在LTE/LTE-A系统中采用disable TB方法，终端设备实现了单独调度SRS的目的。其中，在disable TB方法中，MCS的索引值29～31是用于指示终端设备重传数据的，MCS的索引值0～28是用于指示终端设备传输新数据的，RV的索引值的 优先级从高到低依次为0、2、3、1，RV的索引值为1表征RV是重传的最后一个RV版本；当RV的索引值为1的时候是不适用于指示终端传输新数据的，从而下行控制信息中MCS的索引值为0且RV的索引值1，这样的配置是不太可能出现的，从而可以设置下行控制信息中MCS的索引值为0且RV的索引值1，去指示终端设备不传输数据。
然而在5G网络中，如何指示终端设备进行SRS的调度且不传输数据，这是一个需要解决的问题。
图1为本申请实施例提供的一种SRS传输方法的流程示意图。如图1所示，该方法包括：
S101、终端设备接收网络设备发送的第一配置信息，其中，第一配置信息用于配置物理上行共享信道(physical uplink shared channel，PUSCH)的功率控制参数与SRS的功率控制参数相关联。
示例性地，网络设备向终端设备发送第一配置信息，可选的，第一配置信息承载于无线资源控制(radio resource control，RRC)信令上。例如，第一配置信息承载于一个RRC信令或多个RRC信令上。

可选的，第一配置信息中的一个参数可以被配置为第一参数或第二参数，第一参数表征了PUSCH的功率控制参数与SRS的功率控制参数是相关联的，第二参数表征了PUSCH的功率控制参数与SRS的功率控制参数是不相关联的。例如，高层信令的定义可以为srs-PowerControlAdjustmentStates ENUMERATED{sameAsFci2,separateClosedLoop}。sameAsFci2表征是PUSCH的功率控制参数与SRS的功率控制参数是相关联的，separateClosedLoop表征是PUSCH的功率控制参数与SRS的功率控制参数是不相关联的。一个实施例中，所述第一配置信息可以是一个其它参数或一个阈值，终端设备读取该参数，并根据预先定义好的规则判断PUSCH的功率控制参数与SRS的功率控制参数相关联或不关联。
一个实施例中，在本步骤中，第一配置信息中的一个参数被配置为了第一参数。 举例来说，网络设备向终端设备发送一个高层信令，高层信令为一个RRC信令，例如，高层信令命名为srs-PowerControlAdjustmentStates；高层信令中的一个参数配置为sameAsFci2。

其中，在本实施例中，步骤S101和步骤S102的执行次序不做限定，可以是先执行步骤S101然后执行步骤S102，或者先执行步骤S102然后执行步骤S101，或者同时执行步骤S101和S102。例如，网络设备向终端设备发送第一配置信息，然后，网络设备向终端设备发送下行控制信息；或者，网络设备向终端设备发送下行控制信息，然后，网络设备向终端设备发送第一配置信息；或者，网络设备向终端设备同时发送 第一配置信息和下行控制信息。
S103、终端设备在非周期SRS资源上，根据第一配置信息向网络设备发送SRS。
示例性地，终端设备在根据SRS请求信息确定了一个或多个非周期SRS资源之后，终端设备在每一个非周期SRS资源上，分别向网络设备发送SRS。在可选的一种实施方式中，终端设备读取下行控制信息中的与当前终端设备相关联的块，进而终端设备获取到与当前终端设备相关联的块中的SRS请求信息，然后终端设备根据SRS请求信息，在每一个非周期SRS资源上分别向网络设备发送SRS。
举例来说，若SRS请求信息指示终端设备在一个非周期SRS资源上发送SRS，则终端设备在该非周期SRS资源上向网络设备发送SRS；若SRS请求信息指示终端设备在多个非周期SRS资源上发送SRS，则终端设备在该多个非周期SRS资源中的每一个非周期SRS资源上，分别向网络设备发送SRS。

示例性地，终端设备在向网络设备发送SRS的时候，终端设备需要首先确定出发送SRS时所需要的发送功率。在本实施例中，由于第一配置信息已经配置了PUSCH的功率控制参数与SRS的功率控制参数是相关联的，进而终端设备可以采用PUSCH的功率控制参数，去计算发送SRS时所需要的发送功率；进而终端设备根据PUSCH的功率控制参数，计算出第一发送功率，然后终端设备以第一发送功率，向网络设备发送SRS。
可选的，终端设备需要在多个非周期SRS资源上向网络设备发送SRS的时候，在每个非周期SRS资源上所使用的第一发送功率可以相同或不同。
例如，终端设备需要在非周期SRS资源a、非周期SRS资源b、非周期SRS资源c上，分别向网络设备发送SRS。终端设备可以根据PUSCH的功率控制参数和/或其他参数，计算出第一发送功率，然后终端设备采用相同的第一发送功率分别在非周期SRS资源a、非周期SRS资源b、非周期SRS资源c上，分别向网络设备发送SRS。

示例性地，终端设备在接收到网络设备发送的下行控制信息之后，终端设备获取下行控制信息中的SRS请求信息的值；然后，终端设备根据比特状态信息，确定接收到的SRS请求信息的值所关联的SRS资源集合。
例如，终端设备若确定接收到的SRS请求信息的值为00，则终端设备确定网络设备指示终端设备部调度SRS，即终端设备不需要向网络设备发送SRS；或者，终端设备若确定接收到的SRS请求信息的值为01，则终端设备确定01关联了SRS资源集合1，终端设备需要去寻找SRS资源集合1所包括的非周期SRS资源。

在可选的一种实施方式中，指示信息为天线端口信息，且天线端口信息的域中的比特值全部为1。
在可选的一种实施方式中，指示信息为以下信息中的一种或多种：时域资源的比特值全部为同一个预设值、频域资源的比特值全部为一个预设值、虚拟资源块到物理资源块映射VRB-to-PRB mapping域的比特值为一个预设值。
示例性地，网络设备向终端设备发送下行控制信息，可选的，下行控制信息可以是用于下行调度的下行控制信息，或者，下行控制信息可以是用于上行调度的下行控制信息。
下行控制信息中包括了SRS请求信息和指示信息，SRS请求信息指示终端设备在一个或多个SRS资源集合中的非周期SRS资源上发送SRS，其中，SRS资源集合中包括一个或多个非周期SRS资源。可选的，SRS请求信息占用了下行控制信息的0或2bits的域，SRS请求信息的定义可以参考通信标准的Table 7.3.1.1.2-5。在可选的一种实施方式中，下行控制信息中包括了一个或多个块，每个块与一个终端设备相关联，每个块中包括相关联的终端设备的SRS请求信息和相关联的终端设备的指示信息。
可选的，下行控制信息的格式可以为1_0，即下行控制信息为DCI format 1_0；或者，下行控制信息的格式可以为1_1，即下行控制信息为DCI format 1_1；或者，下行控制信息的格式为只指示终端设备调度SRS的格式；或者，下行控制信息的格式是指示终端设备调度SRS但不调度数据的格式。
可选的，当下行控制信息为用于下行调度的下行控制信息的时候，下行控制信息中还可以包括指示PUSCH的时频资源指示信息、MCS的索引值、RV的索引值、NDI的索引值和天线端口配置。当下行控制信息为用于上行调度的下行控制信息的时候，下行控制信息中还可以包括调度的指示PDSCH的时频资源指示信息、MCS的索引值、RV的索引值、NDI的索引值和天线端口配置。其中，MCS的索引值用于指示传输块的大小以及调制方式，RV的索引值用于指示传输的是数据的第几个冗余版本，NDI的索引值用于指示当前传输是否为新的传输。
可选的，一个非周期SRS资源中包括了SRS的时域资源、频域资源、码域资源和用于发送空间滤波器的资源。
指示信息的含义可以由以下几种实施方式：
第一种实施方式为，指示信息可以为天线端口(antenna ports)信息，天线端口信息用于指示发送PDSCH的端口信息，天线端口信息还可以用于指示预编码信息；在天线端口信息的域中的比特值全部为1的时候，天线端口信息指示终端设备不进行传输数据。可选的，当下行控制信息中的天线端口信息的域中的比特值全部为1的时候，除去SRS请求信息的比特值，下行控制信息中的其他部分域或其他全部域中的比特为预设的固定值，该固定值可以是1或0，例如，下行控制信息中的指示PDSCH的时域资源的比特值、频域资源的比特值、MCS的比特值部分或全部设置为0，或者部分或全部设置为1。
可选的，当指示信息为天线端口信息的时候，下行控制信息的格式为1_1，或者，下行控制信息的格式具有天线端口信息的域的格式。可选的，当下行控制信息的格式为1_1的时候，下行控制信息还可以用于PDSCH的调度。例如，下行控制信息的格式为1_1，即下行控制信息的格式为DCI format 1_1，下行控制信息为DCI 1-1，此时，DCI 1-1中有SRS请求信息的域和天线端口信息的域，可选的，DCI 1-1中还有时频资源的域、频域资源的域、MCS的域等等。
在可选的一种实施方式中，下行控制信息中包括了一个或多个块，每个块与一个终端设备相关联，每个块中包括相关联的终端设备的SRS请求信息和相关联的终端设备的天线端口信息。
在本实施例中，天线端口信息的域中的比特值全部为1可以用于指示终端设备不传输数据的原因是：天线端口信息的域为n比特，n为正整数；但是，在通信标准协 议中定义的天线端口信息的域的比特并不是固定的，即n不是固定值，例如下行的天线端口信息的域可以是4～6比特；对于n个比特的天线端口信息的域，可以指示出2^n个状态，但是不是所有的状态都有对应的天线端口配置。例如，在天线端口信息的域为4比特的时候，天线端口配置与天线端口信息的域的状态的对应关系为:antenna ports(1000+DMRS port(s))，DL-DMRS-config_type＝1，DL-DMRS-max_len＝1，该对应关系在通信标准协议的Table 7.3.1.2.2-1示出了，其中，DMRS指的是解调参考信号(demodulation reference signal)，DL指的是下行链路(down link)，DMRS port(s)指的是DMRS端口，config_type指的是DMRS的类型，max_len指的是DMRS映射的最大符号长度；表2为天线端口信息的域在不同位上的比特值，在表2中，One Codeword指的是单码字，Codeword 0 enabled指的是在单码字为0时所对应的位是处于激活状态的，Codeword 1 disabled指的是在单码字为1时所对应的位是处于非激活状态的，Value指的是天线端口信息的位CDM指的是码分复用(code division multiplexing)，Number of DMRS CDM group(s)without data指的是不传输数据的DMRS CDM组的值，DMRS port(s)指的是DMRS端口，Reserved指的是预留位。
表2天线端口信息在不同位上的比特值
Figure PCTCN2019081461-appb-000001
根据表2可知，12～15这4个位是预留的，是不能用于天线端口指示的。类似的，在天线端口信息的域为5比特的时候，天线端口信息的域的预留位为31或者4～31，此时，天线端口信息的域的预留位为还可以有24～31或者2～31；在天线端口信息的域为6比特的时候，天线端口信息的域的预留位为58～63或者6～63。最高位都是预留的， 最高位对应于天线端口信息的域中的所有比特值都是1的情况；在正常调度PDSCH去指示终端设备传输数据的时候，天线端口信息的域中都不可能是全1的配置，从而当天线端口信息的域中比特值全部为1的时候，可以用于指示终端设备不传输数据。
举例来说，终端设备接收网络设备发送的DCI 1_1，DCI 1_1中包括SRS请求信息和天线端口信息；SRS请求信息的值不是00，进而终端设备可以确定网络设备指示终端设备在非周期SRS资源上发送SRS；并且，天线端口信息的域中的比特值全部为1，进而终端设备可以确定不传输数据。
第二种实施方式为，指示信息可以为以下信息中的一种或多种：时域资源的比特值全部为同一个预设值、频域资源的比特值全部为一个预设值、VRB-to-PRB mapping域的比特值为一个预设值。在网络设备向终端发送的下行控制信息中可以包括以下信息的一种或多种：时域资源、频域资源、VRB-to-PRB mapping；可以通过设置以上信息为预设值，进而指示终端设备不传输数据。例如，下行控制信息中的时域资源的比特值全部为同一个预设值，则终端设备不传输数据；或者，下行控制信息中的频域资源的比特值全部为一个预设值，则终端设备不传输数据；或者，下行控制信息中的VRB-to-PRB mapping域的比特值为一个预设值，则终端设备不传输数据；或者，下行控制信息中的时域资源的比特值全部为同一个预设值，并且下行控制信息中的频域资源的比特值全部为一个预设值，则终端设备不传输数据；或者，下行控制信息中的时域资源的比特值全部为同一个预设值，并且下行控制信息中的VRB-to-PRB mapping域的比特值为一个预设值，则终端设备不传输数据；或者，下行控制信息中的频域资源的比特值全部为一个预设值，并且下行控制信息中的VRB-to-PRB mapping域的比特值为一个预设值，则终端设备不传输数据；或者，下行控制信息中的时域资源的比特值全部为同一个预设值，下行控制信息中的频域资源的比特值全部为一个预设值，并且下行控制信息中的VRB-to-PRB mapping域的比特值为一个预设值，则终端设备不传输数据。
可选的，时域资源的预设值可以是1或0，频域资源的预设值可以是1或0、VRB-to-PRB mapping域的预设值可以是1或0。
可选的，下行控制信息的格式为1_0，或者，下行控制信息的格式具有时域资源、频域资源和VRB-to-PRB mapping中的一种或多种的格式。例如，下行控制信息的格式为1_0，即下行控制信息的格式为DCI format 1_0，下行控制信息为DCI 1_0，可选的，DCI 1_0中还可以有SRS请求信息的域和天线端口信息的域等等。
可选的，当下行控制信息的格式为1_0的时候，下行控制信息还可以用于初始化随机接入流程。例如，DCI 1_0中的某一个或多个比特值配置为指示终端设备进行初始化随机接入流程。可选的，当下行控制信息中的比特值满足一下配置时，则下行控制信息用于初始化随机接入流程：集中式/分布式VRB分配的1个比特值设为0，资源分配的全部比特值设置为1，前导序列标识的比特位数设置为6bit，PRACH mask标识的比特位数设置为4bit，载波指示比特位数设置为0或3bit，DCI格式指示的比特位数设置为1bit，下行控制信息中其他比特值都设置为0。
在可选的一种实施方式中，下行控制信息中包括了一个或多个块，每个块与一个终端设备相关联，每个块中包括相关联的终端设备的SRS请求信息，每个块中包括相 关联的终端设备的时域资源的域、频域资源的域、VRB-to-PRB mapping域中的一种或多种。
可选的，在5G网络支持PDCCH命令(order)信息，则在下行控制信息中还可以包含一个1bit的域，该域用于指示是下行控制信息是支持PDCCH order信息还是支持SRS请求信息。
可选的，在步骤S801之后，终端设备向网络设备发送一个响应消息，响应消息表征了终端设备接收到网络设备发送的下行控制信息。
S802、终端设备在非周期SRS资源上，向网络设备发送SRS。
示例性地，终端设备在根据SRS请求信息确定了一个或多个非周期SRS资源之后，终端设备在每一个非周期SRS资源上，分别向网络设备发送SRS；同时，由于终端设备接收网络设备发送的指示信息，该指示信息指示了终端设备不进行传输数据，从而终端设备只调度SRS但不传输数据。在可选的一种实施方式中，终端设备读取下行控制信息中的与当前终端设备相关联的块，进而终端设备获取到与当前终端设备相关联的块中的SRS请求信息和指示信息，然后终端设备根据SRS请求信息，在每一个非周期SRS资源上分别向网络设备发送SRS，并且终端设备根据指示信息确定不传输数据。
举例来说，若SRS请求信息指示终端设备在一个非周期SRS资源上发送SRS，则终端设备在该非周期SRS资源上向网络设备发送SRS；若SRS请求信息指示终端设备在多个非周期SRS资源上发送SRS，则终端设备在该多个非周期SRS资源中的每一个非周期SRS资源上，分别向网络设备发送SRS。

S83、终端设备在非周期SRS资源上，向网络设备发送SRS。
示例性地，本步骤可以参见图12的步骤S802，不再赘述。
本实施例通过，终端设备接收网络设备发送的下行控制信息，其中，下行控制信息中包括SRS请求信息和指示信息，SRS请求信息指示终端设备在一个或多个SRS资源集合中的非周期SRS资源上发送SRS，指示信息用于指示下行控制信息不使能数据传输；终端设备在非周期SRS资源上，向网络设备发送SRS。从而提供一种指示终端设备调度SRS但不传输数据的方式，可以应用到5G中。指示信息可以为天线端口信息的域中的比特值全部为1，此时不需要改变下行控制信息本身的内容，就可以实现指示终端设备不传输数据的目的。或者，指示信息为时域资源的比特值全部为同一个预设值、频域资源的比特值全部为一个预设值、VRB-to-PRB mapping域的比特值为一个预设值中一种或多种，此时不需要下行控制信息中增加更多的信息或域，复用下行控制信息中本身就存在的域去指示终端设备不传输数据，减少了下行控制信息的开 销，进而降低了网络设备的信令开销。
图14为本申请实施例提供的其他再一种SRS传输方法的流程示意图。如图14所示，该方法包括：
