Description

信道状态信息、参考信号发送方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及信道状态信息发送方法、参考信号发送方法、信道状态信息发送装置、参考信号发送装置、通信装置和计算机可读存储介质。
背景技术
在无线通信网络中，网络侧可以为终端配置多个服务小区serving cell，服务小区可以包括主小区PCell(Primary Cell)、主辅小区PSCell(Primary Secondary Cell)和其他服务小区，也可以称作辅小区SCell。
在相关技术中，为了加快SCell的激活/去激活进程，引入了临时参考信号temporary RS，但是基于temporary RS只能加快SCell的激活/去激活的部分进程，对于加快SCell的激活/去激活的效果并不理想。
发明内容
有鉴于此，本公开的实施例提出了信道状态信息发送方法、参考信号发送方法、信道状态信息发送装置、参考信号发送装置、通信装置和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种信道状态信息发送方法，由终端执行，所述方法包括：确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围；根据所述时域资源范围接收所述SAS-CSI RS；根据所述SAS-CSI RS生成有效信道状态信息valid CSI发送至网络侧设备。
根据本公开实施例的第二方面，提出一种参考信号发送方法，由网络侧设备执行，所述方法包括：确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围；根据所述时域资源范围发送所述SAS-CSI RS。
根据本公开实施例的第三方面，提出一种信道状态信息发送装置，包括一个或多个处理器，所述处理器被配置为执行：确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围；根据所述时域资源范围接收所述SAS-CSI RS；根据 所述SAS-CSI RS生成有效信道状态信息valid CSI发送至网络侧设备。
根据本公开实施例的第四方面，提出一种参考信号发送装置，包括一个或多个处理器，所述处理器被配置为执行：确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围；根据所述时域资源范围发送所述SAS-CSI RS。
根据本公开实施例的第五方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述信道状态信息发送方法。
根据本公开实施例的第六方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现权上述参考信号发送方法。
根据本公开实施例的第七方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述信道状态信息发送方法中的步骤。
根据本公开实施例的第八方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述参考信号发送方法中的步骤。
根据本公开的实施例，网络侧设备并不是持续发送辅小区激活专属的信道状态信息参考信号SAS-CSI RS，而是仅在所述时域资源范围内发送SAS-CSI RS，相应地，终端也只需要在所述时域资源范围内接收SAS-CSI RS。
据此，即使将SAS-CSI RS的周期设置的相对较小，由于网络侧设备仅在所述时域资源范围内发送SAS-CSI RS，在所述时域资源范围外则不发送SAS-CSI RS，因此对于网络侧设备开销的影响很小，终端则相应地仅在所述时域资源范围内接收SAS-CSI RS，在所述时域资源范围外则不接收SAS-CSI RS。有利于确保在不显著增加网络开销的情况下，缩短SAS-CSI RS的周期，使得终端可以更快接收到SAS-CSI RS，进而更快完成valid CSI的上报以完成辅小区的激活。

图1是相关技术中激活SCell的过程示意图。
如图1所示，对于处于去激活状态的SCell，激活SCell的过程主要包括三个步骤：
网络侧通过在向终端发送的介质访问控制层控制元素(Media Access Control Control Element，MAC CE)中携带激活指示，例如通过PCell的物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)携带MAC CE，终端接收到MAC CE后向网络侧设备返回混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信息，例如返回HARQ-ACK，以向网络侧指示终端已接收到MAC CE；这个阶段称作HARQ timing(定时)；
接下来终端接收到MAC CE后进行硬件准备，可以进一步包括多个子步骤，首先解析MAC CE以确定其中携带的具体信息，例如耗时3ms，然后等待接收同步信号块SSB(Synchronization Signal Block)，例如等待时长为T_firstSSB，在接收到SSB之后，进行基于SSB的时频跟踪SSB-based time-frequency tracking；这个阶段称作激活时间Activation Time；
最后终端根据网络侧持续发送的用以激活SCell的信道状态信息参考信号CSI RS(Channel State Information Reference Signal，一般称作P-CSI-RS)生成有效信道状 态信息valid CSI上报给网络侧，网络侧根据valid CSI确定SCell激活；这个阶段称作CSI reporting(报告)。
在此过程中，终端需要先完成时频跟踪，才能根据网络侧持续发送的P-CSI-RS生成valid CSI进行上报，而时频跟踪是基于SSB实现的，因此就需要先接收到SSB。但是如图1所示，SSB的接收是基于SMTC periodicity，也即SSB测量定时配置(SSB Measurement Timing Configuration)周期，但是这个周期相对较长，导致难以及时地完成时频跟踪。针对该问题，相关技术中进一步提出了临时参考信号temporary RS。
图2是相关技术中在激活SCell过程中引入临时参考信号的示意图。
如图2所示，网络侧可以周期性发送temporary RS，并且temporary RS的周期比SMTC periodicity要小，通过MAC CE可以激活终端接收temporary RS，由于temporary RS的周期相对较小，因此在终端在接收到MAC CE后，相对于SSB可以更快地接收到temporary RS，进而根据temporary RS进行自动增益控制设置AGC(Automatic Gain Control)settling和时频跟踪T/F tracking，从而相对于图1的情况，更快地完成时频跟踪，进而更快地完成valid CSI的上报，加快激活SCell的进程。
基于图2可知，通过引入temporary RS可以加快激活SCell的进程，但是经过分析可知，只是加快了激活SCell的部分进程，具体是加快了激活SCell完成时频跟踪的部分。由于终端根据网络侧持续发送的P-CSI-RS生成valid CSI上报，因此完成时频跟踪后到上报valid CSI部分并没有因为引入temporary RS而加快。
而为了加快valid CSI上报，主要的方式之一是缩短P-CSI-RS的周期，以便终端能够更根据P-CSI-RS生成valid CSI进行上报。目前P-CSI-RS的周期最小为4个时隙slot，周期最大为640个时隙slot，由于P-CSI-RS是网络侧持续发送的，缩短P-CSI-RS的周期将会显著地增加网络开销。本公开的实施例主要是针对该技术问题提出的。
图3是根据本公开的实施例示出的一种信道状态信息发送方法的示意流程图。本实施例所示的信道状态信息发送方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图3所示，所述信道状态信息发送方法可以包括以下步骤：
在步骤S301中，确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS 的时域资源范围；
在步骤S302中，根据所述时域资源范围接收所述SAS-CSI RS；
在步骤S303中，根据所述SAS-CSI RS生成有效信道状态信息valid CSI发送至网络侧设备。
在一个实施例中，网络侧设备可以发送(例如广播、单播、组播)辅小区激活专属的信道状态信息参考信号SAS-CSI RS，全称可以为SCell activation specific CSI RS，为了方便描述，以下简称为SAS-CSI RS。
网络侧设备和终端可以分别确定SAS-CSI RS的时域资源范围，例如可以是时间窗，网络侧设备可以在确定的时域资源范围内发送SAS-CSI RS，并且可以在确定的时域资源范围内按照配置给所述终端的配置信息发送SAS-CSI RS。
配置信息可以包括SAS-CSI RS的周期、周期数量(可以理解为发送次数)等，例如周期为N个时隙slot，N小于周期阈值M，M可以根据需要进行设置，例如可以设置M＝10，一般情况下，N的最小值为4，可以适当将N值设置的相对较小，以便终端能够尽快接收到SAS-CSI RS。
终端可以在确定的时域资源范围内接收SAS-CSI RS，例如在确定的时域资源范围内按照网络侧设备配置的配置信息发送SAS-CSI RS。接收到SAS-CSI RS后，终端可以根据SAS-CSI RS生成valid CSI发送至网络侧设备，网络侧设备根据valid CSI可以确定辅小区SCell是否激活。
根据本公开的实施例，网络侧设备并不是持续发送辅小区激活专属的信道状态信息参考信号SAS-CSI RS，而是仅在所述时域资源范围内发送SAS-CSI RS，相应地，终端也只需要在所述时域资源范围内接收SAS-CSI RS。
据此，即使将SAS-CSI RS的周期设置的相对较小，由于网络侧设备仅在所述时域资源范围内发送SAS-CSI RS，在所述时域资源范围外则不发送SAS-CSI RS，因此对于网络侧设备开销的影响很小，终端则相应地仅在所述时域资源范围内接收SAS-CSI RS，在所述时域资源范围外则不接收SAS-CSI RS。有利于确保在不显著增加网络开销的情况下，缩短SAS-CSI RS的周期，使得终端可以更快接收到SAS-CSI RS，进而更快完成valid CSI的上报以完成辅小区的激活。
在一个实施例中，确定所述时域资源范围的方式包括以下至少之一：
根据所述网络侧设备发送的指示信息确定；
根据协议约定确定。
在一个实施例中，SAS-CSI RS的时域资源范围可以根据协议约定确定，在这种情况下，网络侧设备和终端均可根据协议约定确定SAS-CSI RS的时域资源范围，进而网络侧设备可以在该时域资源范围内发送SAS-CSI RS，终端可以在该时域资源范围内接收SAS-CSI RS。
在一个实施例中，SAS-CSI RS的时域资源范围可以由网络侧设备根据需要设置，进而通过指示信息发送给终端，在这种情况下，网络侧设备可以自主确定SAS-CSI RS的时域资源范围，然后通过指示信息指示终端所述时域资源范围，进而网络侧设备可以在所述时域资源范围内发送SAS-CSI RS，终端可以在该时域资源范围内接收SAS-CSI RS。
其中，所述指示信息可以携带在MAC CE中，携带所述指示信息的MAC CE可以与激活temporary RS的MAC CE复用同一个MAC CE，也可以采用其他MAC CE携带所述指示信息。
图4A是根据本公开的实施例示出的另一种信道状态信息发送方法的示意流程图。如图4A所示，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：
在步骤S401中，在接收到临时参考信号temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
在一个实施例中，网络侧设备可以根据协议约定确定在发送temporary RS之后的时域资源中确定所述时域资源范围的起始位置，相应地，终端可以基于协议约定确定在接收到temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
例如可以根据temporary RS所在时隙和偏移量offset(大于或等于0个时隙)确定所述起始位置，例如起始位置为temporary RS所在时隙加上所述偏移量，其中，所述偏移量可以是网络侧设备指示的，或者也是根据协议约定确定的。
在一个实施例中，网络侧设备可以根据需要设置在发送temporary RS之后的时域资源中确定所述时域资源范围的起始位置，进而可以向终端发送指示信息，通过指示信息指示终端在接收到temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
例如可以根据temporary RS所在时隙和偏移量offset确定所述起始位置，例如起始位置为temporary RS所在时隙加上所述偏移量，其中，所述偏移量可以是根据协议约定确定的，或者也是由网络侧设备指示的。
在一个实施例中，由于网络侧设备在给终端配置了temporary RS，且在激活终端接收temporary RS的情况下，才确定存在尽快上报valid CSI的需要，因此，可以在接收到temporary RS之后的时域资源中确定所述时域资源范围的起始位置，以便在接收到temporary RS，确定存在尽快上报valid CSI的需要，终端才从起始位置开始接收SAS-CSI RS，相应地，网络侧设备可以在发送temporary RS之后，才开始发送SAS-CSI RS。有利于避免在无需尽快上报valid CSI的情况下终端接收SAS-CSI RS、网络侧发送SAS-CSI RS而造成资源浪费。
图4B是根据本公开的实施例示出的一种SAS-CSI RS的示意图。
如图4B所示，时域资源范围的起始位置为temporary RS所在时隙加上所述偏移量offset，网络侧设备周期性发送SAS-CSI RS，周围Periodicity可以根据需要配置，时域资源范围的结束位置例如可以为完成valid CSI上报的时域位置。在offset为0的情况下，起始位置可以为temporary RS所在时隙之后的第一个时隙。
图5A是根据本公开的实施例示出的又一种信道状态信息发送方法的示意流程图。如图5A所示，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：
在步骤S501中，在完成自动增益控制设置AGC settling和时频跟踪T/F tracking之后的时域资源中确定所述时域资源范围的起始位置。
在一个实施例中，终端可以根据协议约定确定在完成AGC settling和T/F tracking之后的时域资源中确定所述时域资源范围的起始位置，或者可以根据网络侧设备的指示确定在完成AGC settling和T/F tracking之后的时域资源中确定所述时域资源范围的起始位置。
在这种情况下，终端可以在完成AGC settling和T/F tracking之后的时域资源中确定所述时域资源范围的起始位置，进而在该起始位置开始接收所述SAS-CSI RS。由于AGC settling和T/F tracking是终端执行的动作，网络侧设备并不一定能够确定终端何时完成AGC settling和T/F tracking。
若网络侧设备不能确定终端何时完成AGC settling和T/F tracking，为了确保终 端能够在完成AGC settling和T/F tracking之后接收所述SAS-CSI RS，网络侧设备确定的发送SAS-CSI RS的起始位置可以早于终端确定的接收所述SAS-CSI RS的起始位置。
例如网络侧设备确定的发送SAS-CSI RS的起始位置可以为发送temporary RS之后的第一个时隙slot，或者为发送temporary RS之前的时隙。由于终端需要根据temporary RS进行AGC settling和T/F tracking，因此网络侧设备在发送temporary RS之后的第一个时隙slot，或者在发送temporary RS之前的时隙开始发送SAS-CSI RS，可以确保终端在完成AGC settling和T/F tracking之后的时域位置，能够接收SAS-CSI RS。
若网络侧设备能够确定终端何时完成AGC settling和T/F tracking，那么网络侧设备可以选择将终端完成AGC settling和T/F tracking之后的第一个时隙slot作为发送SAS-CSI RS的起始位置，也可以选择将终端完成AGC settling和T/F tracking之前的时隙slot作为发送SAS-CSI RS的起始位置，据此，也可以确保终端在完成AGC settling和T/F tracking之后的时域位置，能够接收SAS-CSI RS。
在一个实施例中，由于终端在完成AGC settling和T/F tracking之前，网络侧和终端侧可能存在一定程度的不同步，进而导致网络侧设备和终端对于时域资源范围的理解存在不一致，进而导致后续问题。为了避免这种情况，终端可以在完成AGC settling和T/F tracking之后的时域资源中确定所述时域资源范围的起始位置，从而确保在完成AGC settling和T/F tracking之后才会开始接收SAS-CSI RS，确保在网络侧设备和终端对于时域资源范围的理解一致的情况下接收SAS-CSI RS。
图5B是根据本公开的实施例示出的另一种SAS-CSI RS的示意图。
如图5B所示，例如网络侧设备仍然将temporary RS所在时隙加上所述偏移量offset作为起始位置，也即发送起始位置，并在发送起始位置开始发送SAS-CSI RS；而终端在接收到temporary RS之后，需要先完成AGC settling和T/F tracking，进而才能确定接收SAS-CSI RS的起始位置，也即接收起始位置，接收起始位置在AGC settling和T/F tracking之后，确保网络侧设备和终端对于时域资源范围的理解一致的情况下，终端开始接收SAS-CSI RS。在这种情况下，网络侧设备确定的SAS-CSI RS的时域资源范围与终端确定的SAS-CSI RS的时域资源范围可以不同。
在一个实施例中，确定所述时域资源范围的方式包括根据所述网络侧设备的指 示信息确定，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：根据所述指示信息所指示的绝对时间位置确定所述时域资源范围的起始位置。
在网络侧设备通过指示信息指示终端确定时域资源范围的情况下，网络侧设备可以通过指示信息指示绝对时间位置作为时域资源范围的起始位置。
在一个实施例中，确定所述时域资源范围的方式包括根据所述网络侧设备的指示信息确定，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：根据所述指示信息所指示的相对于预设时域位置的偏移量确定所述时域资源范围的起始位置。
在网络侧设备通过指示信息指示终端确定时域资源范围的情况下，网络侧设备可以向终端指示偏移量，终端可以根据预设时域位置和网络侧设备指示的偏移量确定时域资源范围的起始位置。
其中，所述预设时域位置可以是基于协议约定确定的，或者也可以是网络侧设备预先指示的。在一个实施例中，所述预设时域位置包括以下至少之一：
接收到temporary RS的时域位置；
接收到所述指示信息的时域位置；
发送所述指示信息对应的混合自动重传请求HARQ的时域位置对应的下行时隙。
图6是根据本公开的实施例示出的又一种信道状态信息发送方法的示意流程图。如图6所示，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：
在步骤S601中，确定发送所述valid CSI的时域位置为所述时域资源范围的结束位置。
在一个实施例中，由于终端在发送valid CSI后，就已经完成了辅小区的激活/去激活进程，因此在发送valid CSI之后(到下一次需要激活/去激活辅小区之前)，就没有接收SAS-CSI RS了，因此，可以将发送valid CSI的时域位置(例如时隙slot)确定为接收SAS-CSI RS的时域资源范围的结束位置，在结束位置之后，终端停止接收SAS-CSI RS。
相对应地，网络侧设备可以将接收到valid CSI的时域位置确定为发送SAS-CSI RS的时域资源范围的结束位置，在结束位置之后，网络侧设备停止发送SAS-CSI RS。
图7是根据本公开的实施例示出的又一种信道状态信息发送方法的示意流程图。如图7所示，所述根据所述时域资源范围接收所述SAS-CSI RS包括：
在步骤S701中，在确定所述网络侧设备给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，根据所述时域资源范围接收所述SAS-CSI RS。
在一个实施例中，所述方法还包括：
在步骤S702中，在确定所述网络侧设备未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下，不根据所述时域资源范围接收所述SAS-CSI RS。
在一个实施例中，由于网络侧设备在给终端配置了temporary RS，且在激活终端接收temporary RS的情况下，才确定存在尽快上报valid CSI的需要。
因此，终端可以在确定所述网络侧设备给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，才根据所述时域资源范围接收SAS-CSI RS，而在确定所述网络侧设备未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下，则不根据所述时域资源范围接收SAS-CSI RS。
相对应地，网络侧设备可以在确定给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，才根据所述时域资源范围发送SAS-CSI RS，而在确定未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下，则不根据所述时域资源范围发送SAS-CSI RS。
据此，可以避免在无需尽快上报valid CSI的情况下终端接收SAS-CSI RS、网络侧发送SAS-CSI RS而造成资源浪费。
在一个实施例中，所述方法还包括：基于所述SAS-CSI RS执行以下至少一项操作：
将所述SAS-CSI RS作为接收到预设RS之前的其他RS的准共址源QCL source；
根据所述SAS-CSI RS进行干扰测量；
根据所述SAS-CSI RS进行移动性管理。
在一个实施例中，本公开所示实施例中的SAS-CSI RS可以与相关技术中的P-CSI-RS不同，一方面SAS-CSI RS尽在所述时域资源范围内发送和接收，P-CSI-RS则是持续发送的，另一方面SAS-CSI RS的周期相对于P-CSI-RS的周期可以更短，以便终端可以更快地接收到SAS-CSI RS，并据此生成valid CSI完成上报。
在SAS-CSI RS的周期相对于P-CSI-RS的周期较短的情况下，终端一般会更快接收到SAS-CSI RS，那么针对在预设RS之前的其他RS，例如在P-CSI-RS之前的其他RS，可以将SAS-CSI RS作为其他RS的QCL source，有利于更快确定其他RS的QCL source。
例如其他RS可以包括解调参考信号(Demodulation Reference Signal，DMRS)，DMRS为终端激活辅小区后W个时隙slot内的DMRS，W为大于或等于1的整数，可以根据需要设置，例如终端激活辅小区后W个时隙slot内未接收到P-CSI-RS。
另外，基于SAS-CSI RS还可以实现其他功能，例如根据SAS-CSI RS进行干扰测量，根据SAS-CSI RS进行移动性管理(例如根据SAS-CSI RS的接收质量判断是否需要切换小区)等，具体可以根据需要进行拓展，本公开不作具体限制。
图8是根据本公开的实施例示出的一种参考信号发送方法的示意流程图。本实施例所示的参考信号发送方法可以由网络侧设备执行，所述终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等，所述网络侧设备可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图8所示，所述参考信号发送方法可以包括以下步骤：
在步骤S801中，确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围；
在步骤S802中，根据所述时域资源范围发送所述SAS-CSI RS。
在一个实施例中，网络侧设备可以发送(例如广播、单播、组播)辅小区激活专属的信道状态信息参考信号SAS-CSI RS，全称可以为SCell activation specific CSI RS，为了方便描述，以下简称为SAS-CSI RS。
网络侧设备和终端可以分别确定SAS-CSI RS的时域资源范围，例如可以是时 间窗，网络侧设备可以在确定的时域资源范围内发送SAS-CSI RS，并且可以在确定的时域资源范围内按照配置给所述终端的配置信息发送SAS-CSI RS。
配置信息可以包括SAS-CSI RS的周期、周期数量(可以理解为发送次数)等，例如周期为N个时隙slot，N小于周期阈值M，M可以根据需要进行设置，例如可以设置M＝10，一般情况下，N的最小值为4，可以适当将N值设置的相对较小，以便终端能够尽快接收到SAS-CSI RS。
终端可以在确定的时域资源范围内接收SAS-CSI RS，例如在确定的时域资源范围内按照网络侧设备配置的配置信息发送SAS-CSI RS。接收到SAS-CSI RS后，终端可以根据SAS-CSI RS生成valid CSI发送至网络侧设备，网络侧设备根据valid CSI可以确定辅小区SCell是否激活。
根据本公开的实施例，网络侧设备并不是持续发送辅小区激活专属的信道状态信息参考信号SAS-CSI RS，而是仅在所述时域资源范围内发送SAS-CSI RS，相应地，终端也只需要在所述时域资源范围内接收SAS-CSI RS。
据此，即使将SAS-CSI RS的周期设置的相对较小，由于网络侧设备仅在所述时域资源范围内发送SAS-CSI RS，在所述时域资源范围外则不发送SAS-CSI RS，因此对于网络侧设备开销的影响很小，终端则相应地仅在所述时域资源范围内接收SAS-CSI RS，在所述时域资源范围外则不接收SAS-CSI RS。有利于确保在不显著增加网络开销的情况下，缩短SAS-CSI RS的周期，使得终端可以更快接收到SAS-CSI RS，进而更快完成valid CSI的上报以完成辅小区的激活。
在一个实施例中，确定所述时域资源范围的方式包括以下至少之一：
由所述网络侧设备设置；
根据协议约定确定。
在一个实施例中，SAS-CSI RS的时域资源范围可以根据协议约定确定，在这种情况下，网络侧设备和终端均可根据协议约定确定SAS-CSI RS的时域资源范围，进而网络侧设备可以在该时域资源范围内发送SAS-CSI RS，终端可以在该时域资源范围内接收SAS-CSI RS。

其中，所述指示信息可以携带在MAC CE中，携带所述指示信息的MAC CE可以与激活temporary RS的MAC CE复用同一个MAC CE，也可以采用其他MAC CE携带所述指示信息。
图9是根据本公开的实施例示出的另一种参考信号发送方法的示意流程图。如图9所示，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：
在步骤S901中，在接收到临时参考信号temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
在一个实施例中，网络侧设备可以根据协议约定确定在发送temporary RS之后的时域资源中确定所述时域资源范围的起始位置，相应地，终端可以基于协议约定确定在接收到temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
例如可以根据temporary RS所在时隙和偏移量offset(大于或等于0个时隙)确定所述起始位置，例如起始位置为temporary RS所在时隙加上所述偏移量，其中，所述偏移量可以是网络侧设备指示的，或者也是根据协议约定确定的。
在一个实施例中，网络侧设备可以根据需要设置在发送temporary RS之后的时域资源中确定所述时域资源范围的起始位置，进而可以向终端发送指示信息，通过指示信息指示终端在接收到temporary RS之后的时域资源中确定所述时域资源范围的起始位置。
例如可以根据temporary RS所在时隙和偏移量offset确定所述起始位置，例如起始位置为temporary RS所在时隙加上所述偏移量，其中，所述偏移量可以是根据协议约定确定的，或者也是由网络侧设备指示的。

在一个实施例中，确定所述时域资源范围的方式包括由所述网络侧设备设置，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：根据所述网络侧设备设置的绝对时间位置确定所述时域资源范围的起始位置。
在网络侧设备通过指示信息指示终端确定时域资源范围的情况下，网络侧设备可以通过指示信息指示绝对时间位置作为时域资源范围的起始位置。
在一个实施例中，确定所述时域资源范围的方式包括由所述网络侧设备设置，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：根据所述网络侧设备设置的相对于预设时域位置的偏移量确定所述时域资源范围的起始位置。
在网络侧设备通过指示信息指示终端确定时域资源范围的情况下，网络侧设备可以向终端指示偏移量，终端可以根据预设时域位置和网络侧设备指示的偏移量确定时域资源范围的起始位置，网络侧设备也可以根据预设时域位置和网络侧设备指示的偏移量确定时域资源范围的起始位置。
所述预设时域位置可以是基于协议约定确定的，或者也可以是网络侧设备预先指示的。其中，对于网络侧设备和终端而言，偏移量可以相同，但是预设时域位置可以不同。
例如对于网络侧设备而言，所述预设时域位置包括以下至少之一：
发送temporary RS的时域位置；
向所述终端发送指示信息的时域位置，其中，所述指示信息用于指示所述时域资源范围；
接收到所述终端发送的所述指示信息对应的混合自动重传请求HARQ的时域位置对应的下行时隙。
而对于终端而言，所述预设时域位置则包括以下至少之一：
接收到temporary RS的时域位置；
接收到所述指示信息的时域位置；
发送所述指示信息对应的混合自动重传请求HARQ的时域位置对应的下行时隙。
图10是根据本公开的实施例示出的又一种参考信号发送方法的示意流程图。如图10所示，所述确定辅小区激活专属的信道状态信息参考信号SAS-CSI RS的时域资源范围包括：
在步骤S1001中，确定接收到所述终端根据所述SAS-CSI RS生成的有效信道状态信息valid CSI的时域位置为所述时域资源范围的结束位置。
在一个实施例中，由于终端在发送valid CSI后，就已经完成了辅小区的激活/去激活进程，因此在发送valid CSI之后(到下一次需要激活/去激活辅小区之前)，就没有接收SAS-CSI RS了，因此，可以将发送valid CSI的时域位置(例如时隙slot)确定为接收SAS-CSI RS的时域资源范围的结束位置，在结束位置之后，终端停止接收SAS-CSI RS。
相对应地，网络侧设备可以将接收到valid CSI的时域位置确定为发送SAS-CSI RS的时域资源范围的结束位置，在结束位置之后，网络侧设备停止发送SAS-CSI RS。
图11是根据本公开的实施例示出的又一种参考信号发送方法的示意流程图。如图11所示，所述根据所述时域资源范围发送所述SAS-CSI RS包括：
在步骤S1101中，在确定给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，根据所述时域资源范围发送所述SAS-CSI RS。
在一个实施例中，所述方法还包括：
在步骤S1102中，在确定未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下，不根据所述时域资源范围发送所述SAS-CSI RS。
在一个实施例中，由于网络侧设备在给终端配置了temporary RS，且在激活终端接收temporary RS的情况下，才确定存在尽快上报valid CSI的需要。
因此，终端可以在确定所述网络侧设备给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，才根据所述时域资源范围接收SAS-CSI RS，而在确定所述网络侧设备未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下，则不根据所述时域资源范围接收SAS-CSI RS。
相对应地，网络侧设备可以在确定给所述终端配置了temporary RS，且激活所述终端接收temporary RS的情况下，才根据所述时域资源范围发送SAS-CSI RS，而在确定未激活所述终端接收temporary RS或未给所述终端配置temporary RS的情况下， 则不根据所述时域资源范围发送SAS-CSI RS。
据此，可以避免在无需尽快上报valid CSI的情况下终端接收SAS-CSI RS、网络侧发送SAS-CSI RS而造成资源浪费。
在一个实施例中，所述方法还包括：在根据所述时域资源范围发送所述SAS-CSI RS的情况下，停止发送其他与激活所述辅小区相关的CSI-RS。
由于网络侧设备在所述时域资源范围发送所述SAS-CSI RS的情况下，就终端可以根据SAS-CSI RS得到valid CSI进行上报，无需根据其他与激活所述辅小区相关的CSI-RS再生成valid CSI了，所以网络侧设备可以停止(例如在所述时域资源范围内停止)发送其他与激活所述辅小区相关的CSI-RS(例如相关技术中心的P-CSI-RS)，以免浪费网络资源。
与前述的信道状态信息发送方法和参考信号发送方法的实施例相对应，本公开还提供了信道状态信息发送装置和参考信号发送装置的实施例。
