具体地说,该切换方式可以表示频域资源、发送天线和发送波束中的至少一项中需要被切换的对象,和/或被切换的对象如何在该至少一个时域资源 单元中进行切换。
其中,在确定的时域资源单元为一个时,该切换方式可以表示频域资源、发送天线和发送波束中的至少一个中需要被切换的对象,和/或被切换的对象如何在该一个时域资源单元内多个更细粒度的资源间进行切换。
例如,该时域资源单元为子帧,切换方式可以表示频域资源、发送天线和发送波束中的至少一个在该子帧内的多个时隙间被如何切换的方式。
或者,在确定的时域资源单元为多个时,该切换方式可以表示:频域资源、发送天线和发送波束中的至少一个中需要被切换的对象,和/或被切换的对象如何在该多个时域资源单元间进行切换的方式,和/或某个时域资源单元内多个更细粒度的资源间进行切换的方式。

其中,频域资源、发送天线和发送波束中的至少一项在至少一个时域资源单元中切换意味着说:频域资源、发送天线和发送波束中的至少一项在该至少一个时域资源单元上不总是相同的。
具体地,终端设备确定的时域资源单元包括一个时域资源单元时,则频域资源、发送天线和发送波束中的至少一项在该时域资源单元内的更细粒度的多个时域资源中的至少部分时域资源间不同。
例如,该一个时域资源单元为一个子帧,则频域资源、发送天线和发送波束中的至少一项在该子帧内的多个时隙中的至少部分时域资源间不同。
或者,终端设备确定的时域资源单元包括多个时域资源单元时,则频域资源、发送天线和发送波束中的至少一项在某个时域资源单元的多个更细粒度的时域资源间不总是相同的(即在多个时域资源中的至少部分时域资源间不同),或者,频域资源、发送天线和发送波束中的至少一项在该多个时域资源单元间不总是相同的(即在多个时域资源单元中的至少部分时域资源单元间不同)。

例如,终端设备在不同的时域资源单元中采用同一天线阵列中的不同的物理天线来传输SRS,不同时域资源单元上用于传输SRS的物理天线的索引可以根据约定的公式得到,一般采用天线轮询的方式。例如根据时域资源单元的索引来确定当前用于传输SRS的物理天线。在实现中,由于终端射频的限制,上行的射频数目可能少于物理天线数目,为了网络设备能够获得各个物理天线对应的信道,终端设备可以采用轮流发送的方式在各个物理天线上发送SRS。
方式2-2)为:在至少一个时域资源单元中进行不同天线阵列块之间的切换。
例如,终端设备在不同的时域资源单元中采用不同的天线阵列块来传输SRS,不同时域资源单元上传输SRS的天线阵列块可以由终端设备自己确定,也可以由网络侧配置。网络设备接收到多个时域资源单元上发送的SRS后,可以将接收质量最好的SRS信号所在的时域资源单元的索引通知终端设备,从而终端设备后续可以采用对应的天线阵列块来传输其他信号。在具体 实现时,终端设备采用不同天线阵列块发送SRS信号,可以体现为终端设备假设在不同时域资源单元上传输的SRS之间至少在空间参数上不是准同址的
应理解,除了方式2-1)和方式2-2),方式2)还可以包括其他方式,例如,在至少一个时域资源单元上发送SRS的天线阵列可以包括多个天线阵列,多个天线阵列中存在至少一个天线阵列包括多个天线用于在该至少一个时域资源单元上传输SRS,其中,在发送SRS时,每个天线与其他天线相比,所占用的时域资源不同。
方式3)为:在至少一个时域资源单元中进行发送波束的切换。
例如,终端设备在不同的时域资源单元中采用不同的波束来传输SRS,不同时域资源单元上传输SRS的波束可以由终端设备自己确定,也可以由网络侧配置。网络侧接收到多个时域资源单元上采用不同波束发送的SRS后,可以将接收质量最好的SRS信号所在的时域资源单元的索引通知终端设备,从而终端设备后续可以采用对应的波束来传输其他信号。在具体实现时,终端设备采用不同波束发送SRS信号,可以体现为终端设备或网络假设在不同时域资源单元上传输的SRS之间在空间参数上不是准同址(Quasi-co-location,QCL)的。
方式4)为:在至少一个时域资源单元中采用相同的波束和相同频域资源进行传输。
例如,终端设备采用相同的波束和频域资源在所述多个时域资源单元中传输SRS,网络设备可以采用不同的接收波束在多个时域资源单元中接收SRS,从而确定最佳的接收波束。在具体实现时,终端采用相同波束发送SRS信号,可以体现为终端或基站假设在不同时域资源单元上传输的SRS之间在空间参数上是准同址的
可选地,在本申请实施例中,终端设备可以从多个资源利用方式中,选择采用的资源利用方式。例如,从方式1)、方式2-1)、方式2-2)、方式3)方式4)中择一选择一种方式。

在一种实现方式中,SRS资源的参数配置包括网络设备对在至少一个时域资源单元上传输SRS的资源利用方式的配置;根据网络设备对在至少一个 时域资源单元上传输SRS的资源利用方式的配置,终端设备确定资源利用方式。
具体地,所述资源利用方式的配置信息可以与所述SRS资源的其他参数配置一起指示给终端设备,例如通过高层信令指示给终端设备。另外,如果所述SRS资源用于非周期SRS传输,则所述资源利用方式的配置信息可以与非周期SRS的触发信令一起通过下行控制信息(Downlink Control Information,DCI)指示给终端设备。
在一种实现方式中,根据对以下中的至少一种的配置,终端设备确定资源利用方式:

在SRS资源上进行SRS传输的天线端口数;
SRS资源所占用的至少一个时域资源单元的数目;
SRS资源上传输SRS的持续方式;

SRS资源上传输SRS所占用的子载波间隔;
SRS资源的SRS类型。
可选地,SRS资源上传输SRS的持续方式,包括:周期性传输方式、准持续传输方式或非周期性传输方式。
具体地,准持续性传输为通过激活信令激活并可以通过去激活信令停止的SRS传输,非周期传输为通过DCI触发的有限次数的SRS传输,不需要去激活信令停止。
可选地,SRS资源的SRS类型为:用于信道状态信息CSI测量的SRS;或用于波束管理的SRS。
可选地,该SRS类型可以根据发送的SRS的用途进行区分,例如,可以定义两种SRS类型,分别用于上行的CSI测量和上行的发送/接收波束管理。
应理解,除了根据SRS的用途对SRS类型进行区分,还可以根据其他因素对SRS类型进行区分,本申请实施例对此不作具体限定。
为了更加清楚地理解本申请,以下将介绍几种确定资源利用方式的具体实现方式,应理解,以下仅仅是本申请的具体实现方式,不应对本申请构成特别的限定。
在一种实现方式中,当在SRS资源上进行SRS传输的天线端口数小于第一预定值时,确定的资源利用方式为在至少一个时域资源单元中进行发送天线的切换;或,当在SRS资源上进行SRS传输的天线端口数大于等于第二预定值时,确定的资源利用方式为在至少一个时域资源单元中不进行发送天线的切换。
在一种实现方式中,当SRS资源的SRS跳频配置的值为第一值时,确定的资源利用方式为在至少一个时域资源单元中进行频域资源的资源跳频;或,当SRS资源的SRS跳频配置的值不为第一值时,确定的资源利用方式为:

其中,该第一值可选地为1,或0。
在一种实现方式中,终端设备根据所述SRS资源的传输带宽,确定该资源利用方式。
例如,如果SRS资源的传输带宽为用户的大于或等于一定值(例如,用户的整个传输带宽)时,则确定的资源利用方式指示在至少一个时域资源单元中不进行频域资源的资源跳频;如果SRS资源的传输带宽小于一定值时,则确定的资源利用方式指示在至少一个时域资源单元中进行频域资源的资源跳频。
在一种实现方式中,终端根据所述SRS资源上SRS的持续方式,确定该资源利用方式。
例如,当终端设备进行周期性传输或准持续性传输SRS时,则可以确定在至少一个时域资源单元中进行发送波束的切换,在至少一个时域资源单元中采用相同的波束和相同频域资源进行传输,或在至少一个时域资源单元中进行不同天线阵列块之间的切换;当终端设备进行非周期性SRS传输时,则可以确定在至少一个时域资源单元中进行频域资源的资源跳频。
在一种实现方式中,终端设备可以根据所述SRS资源上传输SRS所用的子载波间隔,确定该资源利用方式。
例如,如果该子载波间隔等于确定所述时域资源单元所在时隙的时隙长度的子载波间隔,或者等所述时域资源单元所在的时隙中传输数据的子载波 间隔时,则可以在至少一个时域资源单元中进行频域资源的资源跳频,或,在至少一个时域资源单元中进行同一天线阵列块内的发送天线的切换;
例如,如果所述子载波间隔大于确定所述时域资源单元所在时隙的时隙长度的子载波间隔,或者所述时域资源单元所在的时隙中传输数据的子载波间隔时,则可以在至少一个时域资源单元中进行不同天线阵列块之间的切换,在至少一个时域资源单元中进行发送波束的切换或在至少一个时域资源单元中采用相同的波束和相同频域资源进行传输。
在一种实现方式中,终端根据所述SRS资源的SRS类型,确定传输方式时,如果SRS类型为用于获得CSI的SRS,则可以在至少一个时域资源单元中进行频域资源的资源跳频,或,在至少一个时域资源单元中进行同一天线阵列块内的发送天线的切换;如果SRS类型为用于波束管理的SRS,则可以在至少一个时域资源单元中进行不同天线阵列块之间的切换,在至少一个时域资源单元中进行发送波束的切换或在至少一个时域资源单元中采用相同的波束和相同频域资源进行传输。
在230中,根据确定的资源利用方式,终端设备在至少一个时域资源单元上,进行SRS传输。
可选地,在本申请实施例中,在终端设备在至少一个时域资源单元上,进行SRS传输之后,所述终端设备接收所述网络设备指示的所述至少一个时域资源单元中的目标时域资源单元。
具体地说,网络设备可以根据SRS的接收结果,从该至少一个时域资源单元中选择目标时域资源单元(例如,承载最好的信号质量的SRS的时域资源单元),并向终端设备指示该目标时域资源单元,终端设备可以根据网络设备的指示,发送后续的下行信号。终端设备具体地可以根据在该目标时域资源单元上发送SRS的发送方式,发送后续的下行信号。
例如,终端设备可以利用该目标时域资源单元上发送SRS时所采用的发送波束,发送功率或发送天线等,向网络设备发送后续的下行信号。
因此,在本申请实施例中,终端设备确定在SRS资源上进行SRS传输所占用的至少一个时域资源单元;终端设备确定在至少一个时域资源单元上传输SRS所用的资源利用方式;根据确定的资源利用方式,所述终端设备在至少一个时域资源单元上,进行SRS传输,由此可以实现终端设备可以灵活选择在时域资源单元上传输SRS所用的资源利用方式,从而可以按需实现时 域资源单元的功能。
