本公开涉及通信技术领域，具体而言，涉及激活指示方法、频段激活方法、激活指示装置、频段激活装置、通信装置和计算机可读存储介质。
背景技术
随着通信技术的发展，基站与终端可以在越来越多的频段通信，例如在5G中，已经将通信频段拓展到了FR1和FR2频段。
但是目前基站指示给终端的用于通信的频段存在一些限制，例如一般情况下基站与终端通信所用的频段都是一段连续的频段，或者多个连续的频段，也即通过多个频段通信，但是多个频段是相连的，这可能导致针对某些频段通信受限。
发明内容
有鉴于此，本公开的实施例提出了激活指示方法、频段激活方法、激活指示装置、频段激活装置、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三方面，提出一种激活指示装置，所述装置包括一个或多个处理器，所述处理器被配置为向终端发送激活指示信息，所述终端被配置了至少一个工作在聚合频段的带宽部分BWP，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续，所述BWP对应的带宽包括所述聚合频段中的至少一个子频段；其中，所述激活指示信息用于激活配置的至少一个BWP中的一个BWP以及激活的BWP对应子频段中的至少一个子频段。
根据本公开实施例的第四方面，提出一种频段激活装置，所述装置包括一个或多个处理器，所述处理器被配置为接收基站发送的激活指示信息，所述终端被配置了至少一个工作在聚合频段的带宽部分BWP，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续，所述BWP对应的带宽包括所述聚合频段中的至少一个子频段；根据所述激活指示信息激活配置的至少一个BWP中的一个BWP以及激活的BWP中的至少一个子频段。

根据本公开实施例的第六方面，提出一种计算机可读存储介质，用于存储计算机程序，所述程序被处理器执行时实现上述频段激活方法中的步骤。
根据本公开的实施例，由于BWP对应的带宽包括聚合频段中的至少一个子频段，而激活的BWP对应的至少一个子频段可以不全部工作，因此可以不进可以通过激活指示信息激活BWP，还可以激活BWP子频段中的至少一个子频段。据此，可以提高激活频域资源的精度，有利于满足基站与终端的通信需要。
另外，由于不同子频段属于同一个BWP，不同子频段具有相同的SCS，在切换频段时，可以保持BWP处于激活状态，只需指示不同的子频段，终端就可以改变激活的子频段，无需去激活BWP或者去激活子频段。例如当前激活的子频段为f1，若激活指示信息指示激活f2，则终端可以直接从f1切换到f2，无需去激活f1和f2所在的BWP，也无需去激活f1。有利于降低切换频段的时延，并减少切换过程中的资源 消耗。

图1是根据本公开的实施例示出的一种激活指示方法的示意流程图。本实施例所示的激活指示方法可以由基站执行，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。所述基站可以与作为用户设备的终端进行通信，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1所示，所述激活指示方法可以包括以下步骤：
在步骤S101中，向终端发送激活指示信息，所述终端被配置了至少一个工作在聚合频段的带宽部分BWP，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续，所述BWP对应的带宽包括所述聚合频段中的至少一个子频段；
其中，所述激活指示信息用于激活配置的至少一个BWP中的一个BWP以及激活的BWP对应子频段中的至少一个子频段。
在一个实施例中，在通信频段上可能存在一些零散的频段，这些频段并不连续，并且每个频段的带宽较小，例如在1GHz左右存在一些零散的频段被重耕给5G系统，这些频段的带宽在30M左右。这些频段单独使用难以满足5G通信某些业务场景的需要，例如在进行eMBB(Enhanced Mobile Broadband，增强移动宽带)业务时，所需带宽要达到100M。
在一个实施例中，基站可以确定多个子频段，多个子频段中至少两个相邻的子频段不连续，例如多个子频段中有两个相邻的子频段之间不连续，例如多个子频段中的每个子频段都之间不连续，例如部分子频段之间连续且部分子频段之间不连续。进而基站可以将多个子频段作为一个聚合频段指示给终端，从而使得多个子频段作为一个聚合频段的带宽能够满足大多数业务的需要，使得子频段在自身带宽较小，又与其他子频段不连续的情况下，也能够得到有效的利用。在本公开的所有实施例中，两个相邻的子频段不连续是指，两个相邻的子频段之间具有间隙，即两个子频段之间在频率上不连续。
在一个实施例中，基站可以向所述终端发送配置信息，用于为终端配置工作于所述聚合频段内的至少一个BWP，以及每个所述BWP对应的带宽。终端根据配置信息可以在聚合频段内确定至少一个BWP，并确定每个BWP对应的带宽。在另一个实施例中，UE可以根据相关通信标准确定BWP即该BWP对应的带宽；基站可以根据相关通信标准确定BWP即该BWP对应的带宽；例如协议中提供预定确定方式(例如计算公式)来确定BWP对应的带宽。在又一个实施例中，UE可以和基站协商确定BWP对应的带宽。即，每个BWP对应的带宽可以是基于基站配置的，也可以是基于协议确定的，还可以由基站与UE协商确定。在上述的实施方式中，针对配置的至少一个BWP，还可以向终端发送激活指示信息，以激活其中一个BWP。
根据本公开的实施例，由于BWP对应的带宽包括聚合频段中的至少一个子频段，而激活的BWP对应的至少一个子频段可以不全部工作，因此可以不进可以通过激活指示信息激活BWP，还可以激活BWP子频段中的至少一个子频段。据此，可以提高激活频域资源的精度，有利于满足基站与终端的通信需要。
例如为终端配置4个工作在聚合频段的BWP，分别为BWP1、BWP2、BWP3和BWP4，聚合频段包括三个不连续的子频段f1、f2和f3。需要激活的BWP为BWP4，BWP4对应子频段f1、f2和f3，通过激活指示信息，可以激活BWP4，还可以激活BWP4中的一个或多个子频段，例如激活BWP4对应的f1，从而终端可以在激活的BWP中激活的子频段上与基站通信，例如在BWP4对应的f1上与基站通信。
需要说明的是，所述子频段包括但不限于重耕给5G的零散频段。聚合频段中的每个子频段在聚合之前是独立的频段，聚合后得到的聚合频段作为一个新的频段，具有新的频段标号，不使用目前已有频段的标号。即：聚合频段的标识为唯一的标识，与已有的标识不同。
另外，在相关技术中，针对对应不同频段的BWP，例如BWPx对应频段f1，BWPy对应频段f2，若需要终端从频段f1切换到频段f2，就需要切换BWP。由于不同BWP对应的子载波间隔(Sub-Carrier Spacing，SCS)不同，就需要先去激活BWPx，再激活BWPy，操作步骤较多，占用资源较多，并且时延较大。
而根据本公开的实施例，由于不同子频段属于同一个BWP，不同子频段具有相同的SCS，在切换频段时，可以保持BWP处于激活状态，只需指示不同的子频段，终端就可以改变激活的子频段，无需去激活BWP或者去激活子频段。例如当前激活 的子频段为f1，若激活指示信息指示激活f2，则终端可以直接从f1切换到f2，无需去激活f1和f2所在的BWP，也无需去激活f1。有利于降低切换频段的时延，并减少切换过程中的资源消耗。
图2是根据本公开的实施例示出的一种聚合频段内BWP的示意图。如图2所示，所述BWP对应的带宽包括以下至少之一：
一个完整的子频段、一个子频段中的部分带宽、多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
在一个实施例中，如图2所示，例如聚合频段包括3个子频段f1、f2和f3，其中f1和f3的带宽为30M，f2的带宽为40M，那么聚合频段的带宽为100M。相邻的两个带宽之间存在间隙gap，例如图2所示的两个间隙的带宽相等，均为10M，间隙为不可用(是指针对某个通信系统不可用)的带宽，例如f1、f2和f3被重耕为5G系统，但是间隙并没有被重耕给5G系统，那么间隙在5G系统中就是不可用的。
以为终端在聚合频段配置4个BWP为例，例如BWP1可以对应子频段f1中的部分带宽，BWP2对应完整的子频段f2，BWP3对应两个子频段f2和f3中的部分带宽以及f2和f3之间的间隙，BWP4对应f1、f2、f3这三个完整的子频段，以及这三个子频段之间的两个间隙(在一些可能的实施方式中，可以只有一个间隙；即两个子频段连续，并与第三个子频段之间具有)。
需要说明的是，以上4个BWP对应的带宽只是为了相对全面地表达与子频段的对应关系，具体BWP在聚合频段中的情况并不限于图2所示的实施例，可以根据需要设置。
激活指示信息激活BWP中的某个子频段时，若在BWP中该子频段为完整的子频段，那么激活该完整的子频段，或在BWP该子频段不是完整的子频段，那么则仅激活BWP在该子频段中对应的部分频段。
图3是根据本公开的实施例示出的另一种聚合频段内BWP的示意图。如图3所示，所述方法还包括：
在步骤S301中，向所述终端发送配置信息，其中，所述配置信息用于指示每个所述子频段对应的定时提前量(Timing Advance，TA)和/或准共址(Quasi Co-Location，QCL)类型。
在一个实施例中，在所述子频段包括重耕给5G的零散频段时，由于这部分零散频段在1GHz左右，属于相对低频的频段，基站接收和发送不同频段的信号，可以使用不同的天线，这就会导致每个子频段的TA和QCL类型可能存在差异。
因此，基站可以通过向终端发送配置来配置每个子频段对应的TA，还可以通过配置每个子频段对应的QCL类型，以便终端基于子频段对应的TA和QCL，良好的与基站通信。
例如终端根据配置信息确定子频段f1对应的TA为TA1，子频段f2对应的TA为TA2，那么终端在f1上与基站通信时，可以基于TA1发送上行信号，在f2上与基站通信时，可以基于TA2发送上行信号。
在一个实施例中，所述激活指示信息和/或所述配置信息携带在下行控制信息DCI(Downlink Control Information)中。
其中，所述DCI还可以携带所述激活指示信息，也即基站可以通过DCI向终端发送激活指示信息，以激活BWP对应的一个或多个子频段，并且还可以通过DCI携带需要激活的子频段对应的TA和QCL，从而可以通过一个发送DCI的过程完成激活操作和对TA和QCL的配置操作，有利于节约通信资源。
在一个实施例中，所述聚合频段中的每个子频段分别对应定时提前量和/或准共址类型，或者所述聚合频段对应一个定时提前量和/或准共址类型。
基站可以设置整个聚合频段对应一个TA，也可以设置整个聚合频段对应一个QCL类型；基站还可以设置聚合频段中的每个子频段分别对应TA，例如不同子频段对应不同TA，也可以设置每个子频段分别对应QCL类型，例如不同子频段对应不同QCL类型。
在一个实施例中，所述聚合频段中的每个子频段分别对应定时提前量和/或准共址类型，且定时提前量和/或准共址类型与所述子频段的标识相关联。
在聚合频段中的每个子频段分别对应TA和/或QCL类型的情况下，可以针对聚合频段中的每个子频段设置标识，例如编号，并建立TA和QCL类型与每个子频段标识之间的关联关系，例如可以以表格的形式存在，终端和基站可以预先存储有该关联关系。
需要说明的是，一个子频段可以对应一个TA和/或一个QCL类型，也可以对 应多个TA和/或多个QCL类型。
在对应一个TA和/或一个QCL类型的情况下，基站可以不必向终端发送配置TA和/或QCL类型的配置信息，终端在根据激活指示信息确定激活的子频段时，就可以自行根据关联关系查询激活的子频段对应的TA和/或QCL类型。
在对应多个TA和/或多个QCL类型的情况下，可以针对每个TA和/或每个QCL类型分别设置标识，例如简称T/Q标识，进而在为子频段配置TA和/或QCL类型时，可以将选中的TA和/或QCL类型对应的T/Q标识发给终端，终端可以预先存储有T/Q标识和TA和/或QCL类型的对应关系，进而可以根据接收到的T/Q查询具体的对应的TA和/或QCL类型。
在一个实施例中，所述方法还包括：
向所述终端发送休眠指示信息，用于指示已激活的子频段中至少一个子频段快速休眠。
基站还可以通过休眠指示信息，指示激活的子频段中至少一个子频段快速休眠，例如在激活了多个子频段时，基站根据业务需要确定可以缩小通信带宽，那么可以指示这多个子频段中的一个或多个子频段快速休眠。在这种情况下，基站和终端可以暂时停止使用休眠的子频段，例如基站在休眠的子频段上停止传输下行信号，终端在休眠的子频段上停止接收下行信号，从而使得基站和终端所需维护的带宽缩小，有利于节约资源。
图4是根据本公开的实施例示出的一种频段激活方法的示意流程图。本实施例所示的频段激活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。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图4所示，所述频段激活方法可以包括以下步骤：
在步骤S401中，接收基站发送的激活指示信息，所述终端被配置了至少一个工作在聚合频段的带宽部分BWP，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续，所述BWP对应的带宽包括所述聚合频段中的至少一个子频段；
在步骤S402中，根据所述激活指示信息激活配置的至少一个BWP中的一个 BWP以及激活的BWP中的至少一个子频段。
在一个实施例中，在通信频段上可能存在一些零散的频段，这些频段并不连续，并且每个频段的带宽较小，例如在1GHz左右存在一些零散的频段被重耕给5G系统，这些频段的带宽在30M左右。这些频段单独使用难以满足5G通信某些业务场景的需要，例如在进行eMBB业务时，所需带宽要达到100M。
在一个实施例中，基站可以确定多个子频段，多个子频段中至少两个相邻的子频段不连续，例如多个子频段中有两个相邻的子频段之间不连续，例如多个子频段中的每个子频段之间都不连续，例如部分子频段之间连续且部分子频段之间不连续。进而基站可以将多个子频段作为一个聚合频段指示给终端，从而使得多个子频段作为一个聚合频段的带宽能够满足大多数业务的需要，使得子频段在自身带宽较小，又与其他子频段不连续的情况下，也能够得到有效的利用。在本公开的所有实施例中，两个相邻的子频段不连续是指，两个相邻的子频段之间具有间隙，即两个子频段之间在频率上不连续。
在一个实施例中，基站可以向所述终端发送配置信息，用于为终端配置工作于所述聚合频段内的至少一个BWP，以及每个所述BWP对应的带宽。终端根据配置信息可以在聚合频段内确定至少一个BWP，并确定每个BWP对应的带宽。在另一个实施例中，UE可以根据相关通信标准确定BWP即该BWP对应的带宽；基站可以根据相关通信标准确定BWP即该BWP对应的带宽；例如协议中提供预定确定方式(例如计算公式)来确定BWP对应的带宽。在又一个实施例中，UE可以和基站协商确定BWP对应的带宽。即，每个BWP对应的带宽可以是基于基站配置的，也可以是基于协议确定的，还可以由基站与UE协商确定。在上述的实施方式中，针对配置的至少一个BWP，还可以向终端发送激活指示信息，以激活其中一个BWP。
根据本公开的实施例，由于BWP对应的带宽包括聚合频段中的至少一个子频段，而激活的BWP对应的至少一个子频段可以不全部工作，因此可以不进可以通过激活指示信息激活BWP，还可以激活BWP子频段中的至少一个子频段。据此，可以提高激活频域资源的精度，有利于满足基站与终端的通信需要。
例如为终端配置4个工作在聚合频段的BWP，分别为BWP1、BWP2、BWP3和BWP4，聚合频段包括三个不连续的子频段f1、f2和f3。需要激活的BWP为BWP4，BWP4对应子频段f1、f2和f3，通过激活指示信息，可以激活BWP4，还可以激活BWP4 中的一个或多个子频段，例如激活BWP4对应的f1，从而终端可以在激活的BWP中激活的子频段上与基站通信，例如在BWP4对应的f1上与基站通信。
需要说明的是，所述子频段包括但不限于重耕给5G的零散频段。聚合频段中的每个子频段在聚合之前是独立的频段，聚合后得到的聚合频段作为一个新的频段，具有新的频段标号，不使用目前已有频段的标号。即：聚合频段的标识为唯一的标识，与已有的标识不同。
另外，在相关技术中，针对对应不同频段的BWP，例如BWPx对应频段f1，BWPy对应频段f2，若需要终端从频段f1切换到频段f2，就需要切换BWP。由于由于不同BWP对应的子载波间隔SCS不同，就需要先去激活BWPx，再激活BWPy，操作步骤较多，占用资源较多，并且时延较大。
而根据本公开的实施例，由于不同子频段属于同一个BWP，不同子频段具有相同的SCS，在切换频段时，可以保持BWP处于激活状态，只需指示不同的子频段，终端就可以改变激活的子频段，无需去激活BWP或者去激活子频段。例如当前激活的子频段为f1，若激活指示信息指示激活f2，则终端可以直接从f1切换到f2，无需去激活f1和f2所在的BWP，也无需去激活f1。有利于降低切换频段的时延，并减少切换过程中的资源消耗。
在一个实施例中，所述BWP对应的带宽包括以下至少之一：
一个完整的子频段、一个子频段中的部分带宽、多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
在一个实施例中，如图2所示，例如聚合频段包括3个子频段f1、f2和f3，其中f1和f3的带宽为30M，f2的带宽为40M，那么聚合频段的带宽为100M。相邻的两个带宽之间存在间隙gap，例如图2所示的两个间隙的带宽相等，均为10M，间隙为不可用(是指针对某个通信系统不可用)的带宽，例如f1、f2和f3被重耕为5G系统，但是间隙并没有被重耕给5G系统，那么间隙在5G系统中就是不可用的。
以为终端在聚合频段配置4个BWP为例，例如BWP1可以对应子频段f1中的部分带宽，BWP2对应完整的子频段f2，BWP3对应两个子频段f2和f3中的部分带宽以及f2和f3之间的间隙，BWP4对应f1、f2、f3这三个完整的子频段，以及这三个子频段之间的两个间隙(在一些可能的实施方式中，可以只有一个间隙；即两个子频段连续，并与第三个子频段之间具有)。
需要说明的是，以上4个BWP对应的带宽只是为了相对全面地表达与子频段的对应关系，具体BWP在聚合频段中的情况并不限于图2所示的实施例，可以根据需要设置。
激活指示信息激活BWP中的某个子频段时，若在BWP中该子频段为完整的子频段，那么激活该完整的子频段，或在BWP该子频段不是完整的子频段，那么则仅激活BWP在该子频段中对应的部分频段。
图5是根据本公开的实施例示出的另一种频段激活方法的示意流程图。如图5所示，所述方法还包括：
在步骤S501中，接收所述基站发送的配置信息；
在步骤S502中，根据所述配置信息确定每个所述子频段对应的定时提前量和/或准共址类型。
在一个实施例中，在所述子频段包括重耕给5G的零散频段时，由于这部分零散频段在1GHz左右，属于相对低频的频段，基站接收和发送不同频段的信号，可以使用不同的天线，这就会导致每个子频段的TA和QCL类型可能存在差异。
因此，基站可以通过向终端发送配置来配置每个子频段对应的TA，还可以通过配置每个子频段对应的QCL类型，以便终端基于子频段对应的TA和QCL，良好的与基站通信。
例如终端根据配置信息确定子频段f1对应的TA为TA1，子频段f2对应的TA为TA2，那么终端在f1上与基站通信时，可以基于TA1发送上行信号，在f2上与基站通信时，可以基于TA2发送上行信号。
在一个实施例中，所述激活指示信息和/或所述配置信息携带在下行控制信息DCI中。
其中，所述DCI还可以携带所述激活指示信息，也即基站可以通过DCI向终端发送激活指示信息，以激活BWP对应的一个或多个子频段，并且还可以通过DCI携带需要激活的子频段对应的TA和QCL，从而可以通过一个发送DCI的过程完成激活操作和对TA和QCL的配置操作，有利于节约通信资源。
在一个实施例中，所述聚合频段中的每个子频段分别对应定时提前量和/或准共址类型，或者所述聚合频段对应一个定时提前量和/或准共址类型。
基站可以设置整个聚合频段对应一个TA，也可以设置整个聚合频段对应一个QCL类型；基站还可以设置聚合频段中的每个子频段分别对应TA，例如不同子频段对应不同TA，也可以设置每个子频段分别对应QCL类型，例如不同子频段对应不同QCL类型。
在一个实施例中，所述聚合频段中的每个子频段分别对应定时提前量和/或准共址类型，且定时提前量和/或准共址类型与所述子频段的标识相关联。
在聚合频段中的每个子频段分别对应TA和/或QCL类型的情况下，可以针对聚合频段中的每个子频段设置标识，例如编号，并建立TA和QCL类型与每个子频段标识之间的关联关系，例如可以以表格的形式存在，终端和基站可以预先存储有该关联关系。
需要说明的是，一个子频段可以对应一个TA和/或一个QCL类型，也可以对应多个TA和/或多个QCL类型。
在对应一个TA和/或一个QCL类型的情况下，基站可以不必向终端发送配置TA和/或QCL类型的配置信息，终端在根据激活指示信息确定激活的子频段时，就可以自行根据关联关系查询激活的子频段对应的TA和/或QCL类型。
在对应多个TA和/或多个QCL类型的情况下，可以针对每个TA和/或每个QCL类型分别设置标识，例如简称T/Q标识，进而在为子频段配置TA和/或QCL类型时，可以将选中的TA和/或QCL类型对应的T/Q标识发给终端，终端可以预先存储有T/Q标识和TA和/或QCL类型的对应关系，进而可以根据接收到的T/Q查询具体的对应的TA和/或QCL类型。
在一个实施例中，所述方法还包括：接收所述基站发送的休眠指示信息；所述已激活的子频段中至少一个子频段快速休眠。
基站还可以通过休眠指示信息，指示激活的子频段中至少一个子频段快速休眠，例如在激活了多个子频段时，基站根据业务需要确定可以缩小通信带宽，那么可以指示这多个子频段中的一个或多个子频段快速休眠。在这种情况下，基站和终端可以暂时停止使用休眠的子频段，例如基站在休眠的子频段上停止传输下行信号，终端在休眠的子频段上停止接收下行信号，从而使得基站和终端所需维护的带宽缩小，有利于节约资源。
