背景技术
在LTE(长期演进)系统中子载波间隔为15KHz，一个子帧中包含14个符号(除了特殊子帧外)。上行子帧中最后一个符号可以用来发送上行探测参考信号(Sounding Reference Symbol-SRS)，如图1所示，另外在特殊子帧的上行导频UpPTS(Uplink Pilot Time Slot)中一个或多个符号可以用来发送SRS，如图2所示。基站触发终端非周期发送SRS，即终端根据高层配置参数发送SRS。
但是未来通信系统中同一系统带宽下可能有多种基本系统参数如：子载波间隔。同时由于一个系统带宽内不同的频段的基本参数不同，则上行SRS发送机制不同而且网络侧触发终端发送SRS的方法也不同；而在这种情况下若继续采用LTE系统中的方法触发非周期SRS是不合适的。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图3所示，本公开的实施例提供一种应用于网络侧的通信系统中上行参考信号的触发方法，所述触发方法包括：
步骤31，网络侧生成用于触发终端单次或多次向网络侧发送上行参考信号的触发信令；
步骤32，网络侧向所述终端发送所述触发信令。
相应的，本公开的实施例提供一种应用于终端侧的通信系统中上行参考信号的发送方法，所述通信系统中包含至少两种具有不同信号参数的信号，所述发送方法包括：
步骤41，终端接收网络侧发送的触发信令；
步骤42，所述终端根据所述触发信令单次或多次向网络侧发送上行参考信号。
本公开上述实施例中所述的通信系统中包含的不同信号参数，如图5所示，一个通信系统中一部分由子载波间隔为N Hz的信号构成，另一部分由子载波间隔为M Hz的信号构成；该通信系统的系统带宽下复用基于多种子载波间隔的信号；且由于子载波间隔不同导致符号长度不同。
具体的，与相关技术类似终端在上行资源上有一个或多个符号用来发送上行参考信号。具体的，如图5所示，本公开实施例适用的通信系统中，上行参考信号在不同的频域位置上具有相同或者不同的子载波间隔，且该通信系统中具有子载波相同的一个或多个连续的子载波(图5中该通信系统具有子载波间隔相同的两个连续的子载波)。
具体的，本公开的上述实施例中，所述通信系统中包含至少两种不同的信号参数；且所述信号参数为子载波间隔；所述上行参考信号为上行探测参考信号。
需要说明的是，本公开的上述实施例中网络侧发送的触发信令可以触发终端单次发送上行参考信号，也可以触发终端多次发送上行参考信号。为了更清楚的描述本申请提供的方法，下面从触发终端单次发送上行参考信号以及触发终端多次发送上行参考信号来分别对本申请的方法进行描述。
首先，第一种情况：网络侧发送的触发信令用于触发终端单次发送上行参考信号；需要说明的是，第一种情况下网络侧的触发方法分为2种触发方式，分别为：
第1种触发方式：
本公开的实施例提供的触发方法中步骤31包括：
步骤311，网络侧生成用于触发终端在预设的信号参数对应的频段单次向网络侧发送上行参考信号的第一触发信令。
相应的，本公开的实施例提供的发送方中步骤42包括：
步骤421，所述终端根据网络侧发送的第一触发信令在预设的信号参数对应的频段内多次向网络侧发送上行参考信号。
该种触发方式下，预设的信号参数为一个信号参数。
其中，预设的信号参数，可以是默认的信号参数，即网络侧和终端侧均预先知道预设的信号参数为哪个信号参数。网络侧无需通知终端，终端即可 知道要在哪个信号参数上发送上行参考信号。
或者，预设的信号参数为网络侧事先通过高层信令通知其预设的信号参数；即本公开实施例提供的触发方法还包括：
步骤33，网络侧向终端发送第一高层信令，所述第一高层信令中携带所述预设的信号参数。
相应的，本公开的实施例的发送方法还包括：
步骤43，接收网络侧发送的第一高层信令，所述第一高层信令中携带所述预设的信号参数。
该种方式能够减少触发信令的长度，无需每次在触发信令中通知终端发送上行参考信号的信号参数或者频域位置，避免资源浪费，节省带宽；同时该种触发方式下网络侧不可以动态触发具有不同信号参数的上行参考信号，即每次均是基于网络侧预设的信号参数进行上行参考信号的发送。
或者，预设的信号参数为网络侧通过触发信令告知终端，即在第一触发信令中携带所述预设的信号参数。
该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带信号参数，则终端收到触发信令之后基于触发信令携带的信号参数来发送上行参考信号。
需要说明的是，由于该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带信号参数，则不同的触发信令中可以携带相同或者不同的信号参数，则该种触发方式下网络侧可以动态触发具有不同信号参数的上行参考信号；例如前一个TTI(或子帧)触发基于一种信号参数(如：子载波间隔)的上行探测信号后一个或几个TTI(或子帧)触发基于另一种信号参数的上行探测信号。该种触发方式更具有灵活性及实时性，网络侧可以根据通信系统的实时需求和/或终端的实时需求来实时调整发送上行参考信号的信号参数或者频域位置。
第2种触发方式
本公开的实施例提供的触发方法中步骤31包括：
步骤312，网络侧生成用于触发终端在预设的频域位置上单次向网络侧发送上行参考信号的第二触发信令。
相应的，本公开的实施例提供的发送方中步骤42包括：
步骤422，所述终端根据网络侧发送的第二触发信令在预设的频域位置上单次向网络侧发送上行参考信号。
该种触发方式下，预设的频域位置为一个频域位置。
其中，预设的频域位置，可以是默认的频域位置，即网络侧和终端侧均预先知道预设的频域位置为哪个频域位置。网络侧无需通知终端，终端即可知道要在哪个频域位置上发送上行参考信号。
或者，预设的频域位置为网络侧事先通过高层信令通知其预设的频域位置；即本公开实施例提供的触发方法还包括：
步骤33，网络侧向终端发送第一高层信令，所述第一高层信令中携带所述预设的频域位置。
相应的，本公开的实施例的发送方法还包括：
步骤43，接收网络侧发送的第一高层信令，所述第一高层信令中携带所述预设的频域位置。
该种方式能够减少触发信令的长度，无需每次在触发信令中通知终端发送上行参考信号的频域位置，避免资源浪费，节省带宽；同时该种触发方式下网络侧不可以动态触发具有不同频域位置的上行参考信号，即每次均是基于网络侧预设的频域位置进行上行参考信号的发送。
或者，预设的频域位置为网络侧通过触发信令告知终端，即在第二触发信令中携带所述预设的频域位置。
该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带频域位置，则终端收到触发信令之后基于触发信令携带的频域位置来发送上行参考信号。
需要说明的是，由于该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带频域位置，则不同的触发信令中可以携带相同或者不同的频域位置，则该种触发方式下网络侧可以动态触发具有不同频域位置的上行参考信号；例如前一个TTI(或子帧)触发基于一种频域位置(如：子载波间隔)的上行探测信号后一个或几个TTI(或子帧)触发基于另一种频域位置的上行探测信号。该种触发方式更具有灵活性及实时性，网络侧可以根据 通信系统的实时需求和/或终端的实时需求来实时调整发送上行参考信号的频域位置。
其次，第二种情况：网络侧发送的触发信令用于触发终端多次发送上行参考信号；需要说明的是，第二种情况下网络侧的触发方法也分为2种触发方式，分别为：
第3种触发方式：
本公开的实施例提供的触发方法中步骤31包括：
步骤313，网络侧生成用于触发终端在预设的信号参数对应的频段多次向网络侧发送上行参考信号的第一触发信令。
相应的，本公开的实施例提供的发送方中步骤42包括：
步骤423，所述终端根据网络侧发送的第一触发信令在预设的信号参数对应的频段内多次向网络侧发送上行参考信号。
该种触发方式下，预设的信号参数为一个信号参数或者多个信号参数；当当预设的信号参数为多个信号参数时，所述多个信号参数为多个相同的信号参数或者多个不同的信号参数。需要说明的是，在同一个信号参数对应的频段内发送多次上行参考信号时，需要在不同子带上发送上行参考信号。而多个上行参考信号可以同时发送也可以不同时发送，在此不作具体限定。
其中，预设的信号参数，可以是默认的信号参数，即网络侧和终端侧均预先知道预设的信号参数为哪个信号参数。网络侧无需通知终端，终端即可知道要在哪个信号参数上发送上行参考信号。网络侧向终端发送第一触发信令，终端接收到第一触发信令后在一个信号参数对应的频段的不同子带上多次发送上行参考信号或者在多个信号参数分别对应的频段内多次发送上行参考信号。具体的，发送上行参考信号的不同子带，终端可在预设信号参数对应的频段内随机寻找子带，也可以事先规定在哪些子带上发送，在此不作具体限定。
或者，预设的信号参数为网络侧事先通过高层信令通知其预设的信号参数；即本公开实施例提供的触发方法还包括：
步骤33，网络侧向终端发送第一高层信令，所述第一高层信令中携带所述预设的信号参数。
且由于第一触发信令用于触发终端在预设的信号参数对应的频段内多次向网络侧发送上行参考信号，本公开的第一实施例提供的触发方法还包括：
步骤34，网络侧向终端发送第二高层信令，所述第二高层信令中携带在所述预设的信号参数对应的频段内多次向网络侧发送上行参考信号的跳频规则。
相应的，本公开的实施例提供的发送方法还包括：
步骤44，接收网络侧发送的第二高层信令，所述第二高层信令中携带在所述预设的信号参数对应的频段内多次向网络侧发送上行参考信号的跳频规则。
需要说明的是，该种触发方式下由于终端多次向网络侧发送上行参考信号，网络侧除了利用高层信令通过信号参数或者频域位置之外，还需要利用高层信令通知终端多次发送上行参考信号的跳频规则。例如，终端发送多次上行参考信号时只允许在同一种信号参数的频段内发送多次上行探测信号；或者，终端发送多次上行探测信号时允许在多种信号参数的频段内发送多次上行探测信号，在此不作具体限定。
该种方式能够减少触发信令的长度，无需每次在触发信令中通知终端发送上行参考信号的信号参数或者频域位置，避免资源浪费，节省带宽；同时该种触发方式下网络侧不可以动态触发具有不同信号参数的上行参考信号，即每次均是基于网络侧预设的信号参数进行上行参考信号的发送。
或者，预设的信号参数为网络侧通过触发信令告知终端，即在第一触发信令中携带所述预设的信号参数。
该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带信号参数，则终端收到触发信令之后基于触发信令携带的信号参数来发送上行参考信号。
需要说明的是，由于该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带信号参数，则不同的触发信令中可以携带相同或者不同的信号参数，则该种触发方式下网络侧可以动态触发具有不同信号参数的上行参考信号；例如前一个TTI(或子帧)触发基于一种信号参数(如：子载波间隔)的上行探测信号后一个或几个TTI(或子帧)触发基于另一种信号参 数的上行探测信号。该种触发方式更具有灵活性及实时性，网络侧可以根据通信系统的实时需求和/或终端的实时需求来实时调整发送上行参考信号的信号参数或者频域位置。
第4种触发方式
本公开的实施例提供的触发方法中步骤31包括：
步骤314，网络侧生成用于触发终端在预设的频域位置上多次向网络侧发送上行参考信号的第二触发信令。
相应的，本公开的实施例提供的发送方中步骤42包括：
步骤424，所述终端根据网络侧发送的第二触发信令在预设的频域位置上多次向网络侧发送上行参考信号。
该种触发方式下，预设的频域位置为多个相同或者不同的频域位置。且多个上行参考信号可以同时发送也可以不同时发送，在此不作具体限定。
其中，预设的频域位置，可以是默认的频域位置，即网络侧和终端侧均预先知道预设的频域位置为哪个频域位置。网络侧无需通知终端，终端即可知道要在哪个频域位置上发送上行参考信号。
或者，预设的频域位置为网络侧事先通过高层信令通知其预设的频域位置；即本公开实施例提供的触发方法还包括：
步骤33，网络侧向终端发送第一高层信令，所述第一高层信令中携带所述预设的频域位置。
相应的，本公开的实施例的发送方法还包括：
步骤43，接收网络侧发送的第一高层信令，所述第一高层信令中携带所述预设的频域位置。
该种方式能够减少触发信令的长度，无需每次在触发信令中通知终端发送上行参考信号的频域位置，避免资源浪费，节省带宽；同时该种触发方式下网络侧不可以动态触发具有不同频域位置的上行参考信号，即每次均是基于网络侧预设的频域位置进行上行参考信号的发送。
或者，预设的频域位置为网络侧通过触发信令告知终端，即在第二触发信令中携带所述预设的频域位置。
该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带频 域位置，则终端收到触发信令之后基于触发信令携带的频域位置来发送上行参考信号。
需要说明的是，由于该种触发方式中网络侧每次发送触发信令时，均需在触发信令中携带频域位置，则不同的触发信令中可以携带相同或者不同的频域位置，则该种触发方式下网络侧可以动态触发具有不同频域位置的上行参考信号；例如前一个TTI(或子帧)触发基于一种频域位置(如：子载波间隔)的上行探测信号后一个或几个TTI(或子帧)触发基于另一种频域位置的上行探测信号。该种触发方式更具有灵活性及实时性，网络侧可以根据通信系统的实时需求和/或终端的实时需求来实时调整发送上行参考信号的频域位置。
综上，本公开的上述实施例提供的方法在未来系统包含多种基本参数的情况下网络侧可以灵活触发终端非周期上行探测信号发送。即网络侧根据通信系统的需求和/或终端的需求生成触发信令，并发送给终端；终端接收到触发信令之后根据触发信令的指示非周期性的单次或多次向网络侧发送上行参考信号，从而使得网络侧能够根据上行参考信号进行上行信道质量测量以及上行信道估计；本公开提供的触发方法能够在包含多种基本参数的通信系统中灵活的触发终端非周期发送上行参考信号。
