具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
应理解，本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide  Interoperability for Microwave Access，WiMAX)通信系统、第五代(5-th Generation、5G)移动通信系统，或者说新无线(New Radio,NR)系统，或者为后续演进通信系统。
在本公开实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本公开实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)，或者后续演进通信系统中的网络设备等等，然用词并不构成限制。
如图1所示，本公开的一些实施例提供一种SRS传输方法100，该方法可以应用于终端设备，包括如下步骤：S102、S104和S106。
S102：接收DCI，所述DCI包括资源指示域。
该步骤中，上述资源指示域包括频域资源指示域和时域资源指示域中的至少一种，也即网络设备发送的DCI中可以仅包含频域资源指示域；也可以仅包含时域资源指示域；还可以同时包括频域资源指示域和时域资源指示域。
上述频域资源指示域可以用来指示SRS发送占用的频域资源；时域资源指示域可以用来指示SRS发送占用的时域资源。
本公开实施例中提到的SRS，可以具体是非周期触发的探测参考信号(Aperiodic Sounding Reference Signal，AP-SRS)，或者是半持续探测参考信号(Semi-persistent Sounding Reference Signal，SP-SRS)。
可选地，本公开各个实施例中接收的DCI的格式，与指示物理上行共享 信道(Physical Uplink Shared Channel，PUSCH)或指示物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输的DCI格式相同，也即：该步骤中接收的DCI的格式是复用指示PUSCH传输的DCI格式，或者复用指示PDSCH传输的DCI格式。
通过上述DCI格式复用的方式，避免网络设备配置较多的DCI格式。
可选地，上述DCI的格式还可以为其它的预定义格式，该处提到的预定义格式与指示PUSCH或指示PDSCH传输的DCI格式不同，具体可以是后续演进通信系统中新定义的DCI格式，或者是现有通信系统中的其他DCI格式等等。通过上述DCI格式为其它的预定义格式的方式，方便DCI的灵活实现。
S104：基于所述资源指示域确定所述SRS发送占用的资源。
该步骤中确定的SRS发送占用的资源，具体可以包括时域资源和频域资源，具体如下：
如果DCI中仅包含频域资源指示域，则可以基于该频域资源指示域确定SRS发送占用的频域资源。SRS发送占用的时域资源由高层信令配置。
如果DCI中仅包含时域资源指示域，则可以基于该时域资源指示域确定SRS发送占用的时域资源。SRS发送占用的频域资源由高层信令配置。
如果DCI中同时包括频域资源指示域和时域资源指示域，则可以基于该频域资源指示域确定SRS发送占用的频域资源，同时基于该时域资源指示域确定SRS发送占用的时域资源。
S106：在所述资源上发送所述SRS。
该实施例中，可选地，SRS传输的其他相关参数可以通过高层信令进行半静态配置，上述其他参数例如包括：最大梳齿数和实际传输占用梳齿数；循环移位；特殊子帧占用符号数；周期和时域偏移量；起始占用资源块；跳频带宽和天线端口等。可选地，SRS传输的总带宽可以通过高层信令通知。
本公开实施例提供的SRS传输方法，SRS发送占用的资源是由DCI配置而非RRC信令配置，DCI配置方便灵活，解决了RRC信令配置导致的SRS资源配置灵活性差、时延较大的问题。同时，本公开实施例通过动态的SRS资源指示方式，终端设备能够实现SRS的灵活传输，便于提高SRS的覆盖性能和容量。
可选地，本公开实施例中，上述SRS不占用解调参考信号(DeModulation Reference Signal，DMRS)传输使用的符号，也即上述SRS传输使用的符号和DMRS传输使用的符号不同。
可选地，本公开实施例中，上述DCI可以指示至少一个载波中SRS发送占用的资源。通过上述实施方式，DCI指示至少一个载波的SRS发送占用的资源，能够节约信令开销，同时，DCI可跨载波指示SRS发送占用资源，实现灵活指示。
可选地，本公开实施例中，上述DCI可以指示至少一个时隙或至少一个子帧中SRS发送占用的资源。通过上述实施方式，DCI指示至少一个时隙或至少一个子帧的SRS发送占用的资源，能够节约信令开销。
在图1所示的实施例中提到，终端设备接收到的DCI中包括资源指示域，该资源指示域可以包括频域资源指示域，这样，图1所示的实施例中的步骤S104可以执行如下：
基于所述频域资源指示域确定所述SRS发送占用的物理资源块数和起始物理资源块中的至少一种。也即频域资源指示域可以用来指示SRS发送占用的物理资源块数(起始物理资源块可以由高层信令配置)；还可以用来指示SRS发送占用的起始物理资源块(物理资源块数可以由高层信令配置)；还可以同时用来指示SRS发送占用的起始物理资源块和物理资源块数。
为详细说明，参见图2所示的实施例。该实施例中，终端设备首先接收来自于网络设备的DCI，该DCI可以是格式0，也即该DCI复用指示PUSCH传输的DCI格式，上述接收到的DCI触发AP-SRS发送。
可选地，该DCI的循环冗余校验(Cyclic Redundancy Check，CRC)通过第一无线网络临时标识(Radio Network Temporary Identity，RNTI)进行加扰，所述第一RNTI可以是如下三者中的一种：
探测参考信号无线网络临时标识(Sounding Reference Signal-Radio Network Temporary Identity，SRS-RNTI)、非周期触发的探测参考信号无线网络临时标识(Aperiodic Sounding Reference Signal-Radio Network Temporary Identity，AP-SRS-RNTI)以及半持续探测参考信号无线网络临时标识(Semi-persistent Sounding Reference Signal-Radio Network Temporary Identity， SP-SRS-RNTI)。
上述DCI中包含频域资源指示域，该频域资源指示域指示了SRS发送占用的起始物理资源块位置0和占用的物理资源块数4，具体见图2。
这样，终端设备在接收到DCI后，根据SRS资源指示域指示的起始物理资源块位置0和占用的物理资源块数4，即可在上述物理资源块上传输AP-SRS，即在0-3共4个物理资源块(Physical Resource Block，PRB)上传输AP-SRS。
在图1所示的实施例中提到接收到的DCI中包括资源指示域，该资源指示域可以包括频域资源指示域，这样，图1所示的实施例中的步骤S104具体执行如下：
基于所述频域资源指示域确定所述SRS发送占用的跳频带宽B SRS和C SRS；
基于所述跳频带宽B SRS和C SRS确定所述SRS发送占用的频域资源，为详细说明，以下将结合一个具体的实施例进行描述。
该实施例中，终端设备首先接收来自于网络设备的DCI，该DCI可以是格式8，也即该DCI格式为新定义格式，上述接收到的DCI触发AP-SRS发送。
可选地，该DCI的CRC通过第一RNTI进行加扰，该第一RNTI包括如下一种：SRS-RNTI、AP-SRS-RNTI或SP-SRS-RNTI。
上述DCI中包含频域资源指示域，该频域资源指示域指示了SRS发送占用的跳频带宽B SRS为0，C SRS为0。
这样，终端设备在接收到DCI后，根据跳频带宽B SRS和C SRS取值得到AP-SRS传输占用频域资源，即0-95共96个PRB，则可以在上述资源块上发送AP-SRS。
在上述几个实施例中，SRS发送占用的物理资源块数可以是n的正整数倍，其中，n是大于1的正整数，在一个具体的实施例中，上述n等于4。通过上述设置，DCI可以一次同时指示多个物理资源块，便于节约信令开销。
上述几个实施例中提到DCI包括资源指示域，该资源指示域可以同时包括频域资源指示域和时域资源指示域，这样，除了前文几个实施例介绍的频域资源确定方式之外，图1所示的实施例中的步骤S104还可以用来确定SRS 发送占用的时域资源，具体执行如下：
基于所述时域资源指示域确定SRS发送占用的符号个数和起始符号标识中的至少一种，也即时域资源指示域可以用来指示SRS发送占用的符号个数(起始符号标识可以由高层信令配置)；还可以是用来指示SRS发送占用的起始符号标识(符号个数可以由高层信令配置)；还可以是同时用来指示SRS发送占用的起始符号标识和符号个数。为详细说明，参见图3所示的实施例。
该实施例中，终端设备首先接收来自于网络设备的DCI，该DCI可以是格式8，也即该DCI格式为新定义格式，接收到的DCI触发AP-SRS发送。
上述DCI的CRC可以采用SRS-RNTI、AP-SRS-RNTI或SP-SRS-RNTI进行加扰。
上述DCI中包含时域资源指示域，如图3所示，该时域资源指示域指示了SRS发送占用的起始符号标识0和符号个数为4。
这样，终端设备在接收到DCI后，根据SRS时域资源指示域指示的起始符号标识0和符号个数4，即0-3共4个符号，则可以在上述四个符号上发送AP-SRS。
在前文几个实施例中介绍了本公开实施例接收到的DCI的CRC是通过第一RNTI进行加扰。可选地，网络设备还可以发送预设DCI，该预设DCI的CRC通过第二RNTI进行加扰，上述预设DCI可以用来指示预设SRS发送占用的资源，具体的指示方式可以参照本公开实施例提供的SRS传输方法。
需要说明的，上述提到的预设DCI和预设SRS，只是为了和本公开实施例提供的SRS传输方法中的DCI和SRS进行区分，其中的“预设”两字不代表具体含义。
上述第一RNTI和所述第二RNTI不同，具体地，第二RNTI可以是SRS-RNTI、AP-SRS-RNTI以及SP-SRS-RNTI之外的其他RNTI。
这样，上述SRS和预设SRS可以时分复用传输，为详细说明，以下将结合图4所示的实施例进行介绍。
