交叉引用

在本申请实施例中，网络侧设备在激活目标通信资源的同时，在该目标通信资源上进行上行波束扫描。例如，网络侧设备可以在发送激活目标通信资源的激活信令之后，在接收到终端针对该激活信令的确认信令之前，开始进行上行波束扫描。
通过本申请实施例提供的技术方案，网络侧设备激活终端的目标通信资源，并在激活所述目标通信资源的同时，在所述目标通信资源上进行上行波束扫描，其中，所述目标通信资源包括：辅小区或处于休眠状态的BWP。从而可以缩短目标通信资源的激活和波束扫描时间，缩短目标通信资源从激活到正常通信的时间，提高目标通信资源的激活效率。
图3示出本申请实施例中的通信资源激活方法的另一种流程示意图，该方法300可以由网络侧设备执行。换言之，所述方法可以由安装在网络侧设备上的软件或硬件来执行。在方法300中，通信资源为UE的辅小区。如图3所示，该方法可以包括以下步骤。
S310，网络侧设备激活终端的辅小区。
S312，网络侧设备在激活所述辅小区的同时，在所述辅小区上进行上行波束扫描。
在一个可能的实现方式中，网络侧设备可以通过MAC CE信令激活所述辅小区。
在相关技术中，在辅小区被激活后，网络侧设备在辅小区上配置周期SRS、半持续SRS或非周期SRS，并通过配置一些参数来控制终端具体发送SRS的行为。其中，半持续SRS的相关参数由高层信令(例如，无线电资源控制(Radio Resource Control，RRC)信令)配置。在MAC CE信令激活辅小区之后的规定的时间后，终端可以按照RRC配置的SRS的相关参数开始发送半持续SRS直到终端接收到基站的去激活命令为止。非周期SRS的相关参数由RRC配置，在下行控制信息(Downlink Control Information，DCI)中触发终端发送单次SRS。RRC配置参数包括时域参数如SRS资源符号位置、占用符号数目、跳频、repetition参数R等。因此，在相关技术中，从网络侧设备激活辅小区到接收SRS的时间较长。
因此，在上述可能的实现方式中，可选的，激活所述辅小区的MAC CE信令还用于触发所述终端在所述辅小区上发送目标SRS。通过该可选的实现方式，可以在激活辅小区的同时，触发终端在该辅小区上发送目标SRS，缩短了从网络侧设备激活辅小区到接收目标SRS的时间，进而使得网络侧设备可以更快的扫描到上行波束，缩短从激活辅小区到真正使用所述辅小区的时间。
在一个可能的实现方式中，网络侧设备可以预先配置SRS的N个候选状态，每个候选状态对应所述目标SRS的至少一个配置参数，则所述MAC CE信令在激活所述辅小区的同时，可以触发目标SRS的N个候选状态中的一个目标状态。例如，假设MAC CE信令中有一个2比特 的指示域用于指示触发的目标SRS的状态，则该目标SRS可以有4个候选状态值，即00、01、10和11，在预先配置中，这4个候选状态可以分别对应不同的目标SRS的配置参数。例如，00代表SRS资源1偏移值为x，01代表SRS资源1偏移值y，10代表重复发送等。当然，并不限于此，在具体应用中，一个候选状态也可以对应目标SRS的多个配置参数(即一组配置参数)，具体本申请实施例中不作限定。
在上述可能的实现方式中，终端在接收到所述MAC CE命令后，激活辅小区，在辅小区激活完成的同时发送目标SRS，该目标SRS可以是周期SRS或非周期SRS或半持续SRS。例如，在终端接收激活辅小区的MAC CE信令并反馈对应的确认命令ACK给网络后3ms，该辅小区真正被激活，在辅小区真正被激活的同时终端根据MAC CE信令中指示的SRS触发状态发送目标SRS。
在另一个可能的实现方式中，所述MAC CE信令中可以携带有终端发送所述目标SRS的时间偏移值。其中，该时间偏移值是指在激活辅小区的MAC CE信令对应的确认(ACK)发送之后的预定时延(可以是协议规定的时延，比如3ms)的基础上额外的时间偏移值，针对多个辅小区，该时间偏移值可以相同或不同。终端在接收到该MAC CE命令后，在反馈ACK后的预定时延+该时间偏移值到达时，发送所述目标SRS。可选的，该时间偏移值也可以不携带在MAC CE信令中，而是事先由高层信令配置的。
在具体应用中，一个SRS集合里可能有多于1个的SRS资源，而每个SRS资源配置不同的时域资源上，例如，不同符号。因此，一个可能的实现方式中，在激活辅小区的所述MAC CE信令中可以同时指示是 否重复，即所述MAC CE信令中携带有指示所述目标SRS是否重复的指示信息。例如，repetition ON或OFF。在repetition为ON的情况下，即指示所述目标SRS重复的情况下，终端可以在一个SRS集合里的各个SRS资源上，使用相同的发送波束发送所述目标SRS。而在repetition为OFF的情况下，即指示信息指示所述目标SRS不重复的情况下，终端在一个SRS集合里的各个SRS资源上，使用不同的发送波束发送所述目标SRS。
在一个可能的实现方式中，对于半持续SRS或周期性SRS，激活辅小区的所述MAC CE信令中可以指示时间窗长度，即所述MAC CE信令中携带有指示时间窗长度的指示信息，指示所述终端在与所述时间窗长度对应的时间窗内发送所述目标SRS，其中，所述目标SRS为周期SRS或半持续SRS。在该可能的实现方式中，在辅小区被激活之后，终端在与所述时间窗长度对应的时间窗内发送所述目标SRS，在该时间窗外不发送所述目标SRS。另外，在实际应用中，所述时间窗长度也可以不在所述MAC CE信令中指示，而是事先定义或约定的，具体本申请实施例中不作限定。
在一个可能的实现方式中，所述MAC CE信令中携带有指示所述目标SRS的发送功率偏移量的指示信息。在实际应用中，网络侧设备可以针对每个辅小区单独指示该发送功率偏移量，或者，网络侧设备也可以根据各个辅小区的载波频率的平均功率增益差来确定所述发送功率偏移量，具体本申请实施例不作限定。
在一个可能的实现方式中，网络侧设备也可能通过MAC CE信令激活辅小区，另外使用DCI信令触发所述辅小区上的目标SRS，该目标 SRS为非周期SRS或半持续SRS的发送。因此，在该可能的实现方式中，在通过MAC CE信令激活所述辅小区之后，该方法还可以包括：所述网络侧设备通过DCI信令触发所述终端在所述辅小区上发送目标SRS。
例如，所述网络侧设备可以在接收到所述MAC CE信令对应的确认信令(ACK)之前，发送所述DCI信令；或者，所述网络侧设备也可以在接收到所述确认信令之后的预定时延(例如，3ms)到达前，发送所述DCI信令。从而可以提前触发终端在所述辅小区上发送非周期SRS或半持续SRS。
在具体应用中，一个SRS集合里可能有多于1个的SRS资源，而每个SRS资源配置不同的时域资源上，例如，不同符号。因此，在上述可能的实现方式中，可选的，在所述DCI信令中可以携带有指示所述目标SRS是否重复的指示信息，例如，repetition ON或OFF。在repetition为ON的情况下，即指示所述目标SRS重复的情况下，终端可以在一个SRS集合里的各个SRS资源上，使用相同的发送波束发送所述目标SRS。而在repetition为OFF的情况下，即指示信息指示所述目标SRS不重复的情况下，终端在一个SRS集合里的各个SRS资源上，使用不同的发送波束发送所述目标SRS。
在上述可能的实现方式中，可选的，所述DCI信令中还可以携带有所述终端发送所述目标SRS的时间偏移值，其中，该时间偏移值是指在激活辅小区的MAC CE信令对应的确认(ACK)发送之后的预定时延(可以是协议规定的时延，比如3ms)的基础上额外的时间偏移值，针对多个辅小区，该时间偏移值可以相同或不同。终端在接收到该DCI命令后，在反馈ACK后的预定时延+该时间偏移值到达时，发送所述目 标SRS。可选的，该时间偏移值也可以不携带在DCI信令中，而是事先由高层信令配置的。
在上述可能的实现方式中，可选的，所述DCI信令中携带有指示时间窗长度的指示信息，指示所述终端在与所述时间窗长度对应的时间窗内发送所述目标SRS。在该可能的实现方式中，在辅小区被激活之后，终端在与所述时间窗长度对应的时间窗内发送所述目标SRS，在该时间窗外不发送所述目标SRS。另外，在实际应用中，所述时间窗长度也可以不在所述DCI信令中指示，而是事先定义或约定的，具体本申请实施例中不作限定。
在上述可能的实现方式中，可选的，所述DCI信令中携带有指示所述目标SRS的发送功率的指示信息。网络侧设备可以参考路损参考信号确定在被激活的辅小区上发送目标SRS的发送功率，其中，路损参考信号可以为其他已经激活的载波上的参考信号。
在一个可能的实现方式中，网络侧设备通过RRC信令激活所述辅小区，其中，所述RRC信令用于配置所述辅小区。也就是说，在该可能的实现方式中，网络侧设备可以在使用RRC信令配置辅小区(SCell)的同时激活该辅小区，而不需要额外MAC CE信令对该辅小区进行激活，从而可以缩短辅小区激活的时间。
在上述可能的方式中，通过RRC信令激活所述辅小区的情况下，可选的，可以使用MAC CE信令或DCI信令触发UE发送目标SRS，具体方式可以参见上面的相关描述，在此不再赘述。
图4示出本申请实施例中的通信资源激活方法的另一种流程示意图，该方法400可以由网络侧设备执行。换言之，所述方法可以由安装在网 络侧设备上的软件或硬件来执行。在方法400通信资源为UE的处于休眠状态的BWP。如图4所示，该方法可以包括以下步骤。
S410，网络侧设备激活终端的处于休眠状态的BWP。
S412，网络侧设备在激活所述BWP的同时，在所述BWP上进行上行波束扫描。
在一个可能的实现方式中，所述网络侧设备通过DCI信令激活所述处于休眠状态的BWP。例如，可以在DCI信令中携带激活的所述处于休眠状态的BWP的标识。
在一个可能的实现方式中，所述DCI信令还用于触发所述终端在所述BWP上发送目标SRS，其中，所述目标SRS为非周期SRS或半持续SRS。通过该可能的实现方式，可以在激活BWP的同时，触发终端在所述BWP上发送目标SRS。
在具体应用中，一个SRS集合里可能有多于1个的SRS资源，而每个SRS资源配置不同的时域资源上，例如，不同符号。因此，在上述可能的实现方式中，可选的，在所述DCI信令中可以携带有指示所述目标SRS是否重复的指示信息。例如，repetition ON或OFF。在repetition为ON的情况下，即指示所述目标SRS重复的情况下，终端可以在一个SRS集合里的各个SRS资源上，使用相同的发送波束发送所述目标SRS。而在repetition为OFF的情况下，即指示信息指示所述目标SRS不重复的情况下，终端在一个SRS集合里的各个SRS资源上，使用不同的发送波束发送所述目标SRS。
在上述可能的实现方式中，可选的，所述DCI信令中还可以携带有所述终端发送所述目标SRS的时间偏移值，其中，该时间偏移值是指在 BWP激活DCI信令对应的确认(ACK)发送之后的预定时延(可以是协议规定的时延，比如3ms)的基础上额外的时间偏移值，针对多个BWP，该时间偏移值可以相同或不同。终端在接收到该DCI命令后，在反馈ACK后的预定时延+该时间偏移值到达时，发送所述目标SRS。可选的，该时间偏移值也可以不携带在DCI信令中，而是事先由高层信令配置的。
在上述可能的实现方式中，可选的，所述DCI信令中携带有指示时间窗长度的指示信息，指示所述终端在与所述时间窗长度对应的时间窗内发送所述目标SRS。在该可能的实现方式中，在BWP被激活之后，终端在与所述时间窗长度对应的时间窗内发送所述目标SRS，在该时间窗外不发送所述目标SRS。另外，在实际应用中，所述时间窗长度也可以不在所述MAC CE信令中指示，而是事先定义或约定的，具体本申请实施例中不作限定。
在上述可能的实现方式中，可选的，所述DCI信令中携带有指示所述目标SRS的发送功率的指示信息。网络侧设备可以参考路损参考信号确定在被激活的BWP上发送目标SRS的发送功率，其中，路损参考信号可以为其他已经激活的BWP上的参考信号。
通过上述实施例，可以缩短BWP从激活到真正使用的时间，并且，可以在激活BWP的同时，触发UE发送目标SRS，缩短了BWP从激活到能扫描到上行波束的时间。
图5示出本申请实施例中的SRS的发送方法的另一种流程示意图，该方法500可以由终端执行。换言之，所述方法可以由安装在终端上的软件或硬件来执行。如图5所示，该方法可以包括以下步骤。
S510，终端接收目标通信资源激活信令。
其中，目标通信资源激活信令为网络侧设备发送的激活目标通信资源的激活信令，其具体实现方式可以参见方法200至400中的相关描述，在此不再赘述。
S512，在完成所述目标通信资源激活信令所指示的目标通信资源的激活的同时，所述终端在所述目标通信资源上发送目标SRS，其中，所述目标通信资源包括所述终端的辅小区或处于休眠状态的BWP。
如上述方法300中所述，如果目标通信资源为所述终端的辅小区，则目标通信资源激活信令可以包括：用于激活所述终端的辅小区的MAC CE信令。
如方法300中所述，可以由所述MAC CE信令触发所述终端在被激活的辅小区上发送目标SRS，或者，也可以由DCI信令触发所述终端在被激活的辅小区上发送目标SRS，下面分别针对这两种情况进行说明。
(一)所述MAC CE信令还用于触发所述终端在被激活的辅小区上发送目标SRS。
在一个可能的实现方式中，所述MAC CE信令在激活所述辅小区的同时，触发N个状态中的一个状态，其中，所述N个状态为预先为所述目标SRS配置的N个状态，每个状态对应所述目标SRS的至少一个配置参数，N为大于等于1的整数。终端根据该MAC CE可以确定目标SRS的一个配置参数或一组配置参数。例如，假设MAC CE信令中有一个2比特的指示域用于指示触发的目标SRS的状态，则该目标SRS可以有4个候选状态值，即00、01、10和11，在预先配置中，这4个候选状态可以分别对应不同的目标SRS的配置参数。例如，00代表SRS资源1偏移值为x，01代表SRS资源1偏移值y，10代表重复发送等。 如果接收到的MAC CE中该指示域的值为10，则指示所述目标SRS重复发送。
因此，在该可能的实现方式中，在完成所述目标通信资源激活信令所指示的目标通信资源的激活的同时，所述终端在所述目标通信资源上发送目标SRS，包括：
所述终端在反馈所述MAC CE信令对应的确认信令后的预定时延之后，根据所述MAC CE命令触发的状态，在所述辅小区上发送所述目标SRS。

所述终端在所述时间偏移值所述指示的时刻发送所述目标SRS。
在具体应用中，一个SRS集合里可能有多于1个的SRS资源，而每个SRS资源配置不同的时域资源上，例如，不同符号。因此，发送目标SRS可以包括：若所述MAC CE信令指示所述目标SRS重复，则所述终端采用相同的发送波束在各个SRS资源上发送所述目标SRS；或者，若所述MAC CE信令指示所述目标SRS不重复，则所述终端在不同的SRS资源采用不同的发送波束发送所述目标SRS。例如，在该指示信息指示所述目标SRS重复的情况下，终端可以在一个SRS集合里的各个 SRS资源上，使用相同的发送波束发送所述目标SRS。而在指示信息指示所述目标SRS不重复的情况下，终端在一个SRS集合里的各个SRS资源上，使用不同的发送波束发送所述目标SRS。

在具体应用中，一个SRS集合里可能有多于1个的SRS资源，而每个SRS资源配置不同的时域资源上，例如，不同符号。因此，在一个可能的实现方式中，发送目标SRS可以包括：若所述DCI信令指示所述目标SRS重复，则所述终端采用相同的发送波束在各个SRS资源上发送所述目标SRS；或者，若所述DCI信令指示所述目标SRS不重复，则所述终端在不同的SRS资源采用不同的发送波束发送所述目标SRS。即在该可能的实现方式中，在所述DCI信令中可以携带有指示所述目标SRS是否重复的指示信息。例如，repetition ON或OFF。在repetition为ON的情况下，即指示所述目标SRS重复的情况下，终端可以在一个SRS集合里的各个SRS资源上，使用相同的发送波束发送所述目标SRS。而在repetition为OFF的情况下，即指示信息指示所述目标SRS不重复的情况下，终端在一个SRS集合里的各个SRS资源上，使用不同的发送波束发送所述目标SRS。

在一个可能的实现方式中，发送目标SRS包括：所述终端在与时间窗长度对应的时间窗内发送所述目标SRS，其中，所述时间窗长度为所述DCI信令指示的或预先定义的。在该可能的实现方式中，在辅小区被激活之后，终端在与所述时间窗长度对应的时间窗内发送所述目标SRS，在该时间窗外不发送所述目标SRS。
在一个可能的实现方式，可选的，所述DCI信令中携带有指示所述目标SRS的发送功率的指示信息。因此，发送目标SRS可以包括：所述终端根据所述DCI信令指示的发送功率，发送所述目标SRS。
如果目标通信资源为处于休眠状态的BWP，则在一个可能的实现方式中，所述目标通信资源激活信令包括：用于激活所述处于休眠状态的BWP的DCI信令。
在一个可能的实现方式中，所述DCI信令还用于触发所述终端在所述BWP上发送所述目标SRS。
