Description

一种确定BWP状态的方法、设备及系统
本申请要求于2017年12月29日提交中国专利局、申请号为201711483336.8、申请名称为“一种确定BWP状态的方法、设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种确定带宽部分(Bandwidth Part，BWP)状态的方法、设备及系统。
背景技术
第五代(5th-Generation，5G)移动通信新空口(New Radio，NR)标准化工作，讨论了带宽能力小于系统带宽的终端设备的数据传输情况。例如：在无线接入网络(Radio Access Network，RAN)1#88会议上，讨论通过两步资源分配方式来支持带宽能力小于系统带宽的终端设备的数据传输，即为终端设备先指示一个BWP，再在该带宽部分进行资源分配和数据传输。在RAN1#88b会议上，进一步明确了对于一个载波，网络可以通过半静态方式为终端设备配置一个或多个带宽部分，每个带宽部分的带宽不大于终端设备最大带宽能力。在RAN1#89会议上，讨论并支持通过激活/去激活带宽部分的方式实现同一载波上多个带宽部分之间的切换。
图1为典型的带宽部分切换的场景，如图1所示。终端设备被配置两个带宽部分：BWP1和BWP2，其中BWP1的带宽较小，BWP2的带宽较大，当待传业务量较小时，终端设备只在BWP1上监听PDCCH，即此时小带宽的带宽部分是激活的，而大带宽的带宽部分是去激活的；当待传数据量较大时，终端设备根据跨BWP调度(Cross-BWP Grant)切换到BWP2上，在大带宽的带宽部分上检测PDCCH，即此时小带宽的带宽部分被去激活，而大带宽的带宽部分被激活，如此，实现同一载波内BWP间的切换。
由图1可知，在BWP切换之前，终端设备需要获知BWP的激活/去激活状态，以便切换到被的激活BWP上。但是，目前终端设备难以确定BWP的状态。尤其是，作为NR中的一种频率资源部署形式，在NR中还引入了载波聚合(Carrier Aggregation，CA)，即引入多个组成载波(Component Carrier，CC)，且在每个cc中可能会配置多个不同的BWP，对于这么多载波上的多BWP，如何确定载波上BWP的激活/去激活状态成为NR中亟待讨论的问题。

需要说明的是，在本申请各实施例中，激活/去激活可以指：激活、或者去激活两种情况中的任一种情况，如：带宽部分的激活/去激活状态可以包括：带宽部分被激活、带宽部分去激活两种状态中的任一状态。
下面结合图2所示的通信系统，对本申请实施例提供的确定BWP状态的方法进行详细描述，其中，下述方法实施例中的设备可对应包含图3所示的组成部件。需要说明的是，虽然在下述方法流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图4为本申请实施例提供的一种确定BWP状态的方法流程图，由图2所示的终端设备和接入网设备交互执行，如图4所示，该方法可以包括：
步骤401：接入网设备为终端设备配置第一载波上的至少一个BWP。
其中，作为一个例子，所述接入网设备可以为图2中的接入网设备，终端设备可 以为图2中的终端设备。
第一载波可以为接入网设备预先配置给终端设备的一个或者多个载波中的任一载波，可以为单个载波，还可以为多个载波中的任一组成载波(Component Carrier，CC)，第一载波上的至少一个BWP中可以包含多个激活BWP和去激活BWP，其中，激活BWP可以指处于状态的BWP，去激活BWP可以指处于去激活状态的BWP。第一载波上的至少一个BWP可以包括激活BWP，还可以包括去激活BWP，不予限制。
可选的，接入网设备可以采用高层信令配置为终端设备配置第一载波上的至少一个BWP、以及第一载波上每个BWP的激活/去激活状态，在此不再赘述。
其中，带宽部分与BWP为同等概念，带宽部分可以为频域上一段连续或非连续的资源，与一个特定的系统参数相关，所述系统参数包括子载波间隔和循环前缀(Cyclic Prefix，CP)的至少一种；如：一个带宽部分包含连续或非连续的K个子载波；或者，一个带宽部分为K个不重叠的连续或非连续的资源块(Resource Block，RB)所在的频域资源；或者，一个带宽部分为K个不重叠的连续或非连续的资源块组(Resource Block Group，RBG)所在的频域资源，一个RBG包括P个连续的RB，其中，K为大于0的整数，P为大于0的整数，不予限制。
步骤402：接入网设备向终端设备发送指示信息，其中，所述指示信息用于指示第一载波上的带宽部分的激活/去激活状态。
上述指示信息可以有多种设计形式，如：可以如图5a所示包括多个比特图(Bit Map)，还可以如图5b所示包括一个比特图，又可以如图5c所示为承载在第一载波上的包括多个比特位的信息，也可以如图5d所示为包含载波的标识信息以及载波上的带宽部分的标识信息的信息等，不予限制。具体的，本申请实施例中指示信息的设计形式可参照下述相关描述，在此不再赘述。
可选的，接入网设备将指示信息携带在MAC CE中或者其他信令消息中向终端设备发送，终端设备从携带有指示信息的MAC CE中或者其他信令消息中接收指示信息。
需要说明的是，当指示信息携带在MAC CE中时，该指示信息在MAC CE中占用的比特位可以由网络预先配置，也可以由协议规定，还可以在MAC CE的某个比特位包含用于指示该指示信息所处位置的位置指示，以便终端设备接收到MAC CE后，根据该位置指示获取指示信息，如：可以在MAC CE的0-n比特位携带该指示信息，n为大于0的整数。其中，网络预先配置可以指：网络侧设备将该指示信息在MAC CE中所处位置的相关信息携带在专门的配置信令中配置给终端设备，且该配置可以刷新、更改；协议规定可以指：在通信协议规定的标准中明确该指示信息在MAC CE中所处位置，且该标准无法刷新、更改。
此外，MAC CE除包含指示信息之外，还可以包含其他信息(如空白填充、报文头(Header)等)，不予限制。
步骤403：终端设备接收接入网设备发送的指示信息，根据指示信息在第一载波的激活BWP上监测PDCCH。
其中，终端设备接收接入网设备发送的指示信息还可以描述为终端设备接收来自接入网设备的指示信息。
具体的，终端设备接收到指示信息之后，根据指示信息的指示确定第一载波上各 带宽部分的激活/去激活状态，在激活BWP上监测PDCCH，而在去激活BWP上不监测PDCCH，以此降低终端设备的功耗。
其中，当指示信息携带在MAC CE中时，终端设备可以从网络预配置给终端设备的信息中确定MAC CE中携带指示信息的比特位，或者从协议规范中确定MAC CE中携带指示信息的比特位，或者从MAC CE中携带的用于指示指示信息所处位置的位置指示确定MAC CE中携带指示信息的比特位。例如，若接入网设备向终端设备发送MAC CE1，该MAC CE1的第1-6比特位携带指示信息，则当终端设备接收到MAC CE1后，从MAC CE1的第1-6比特位获取指示信息，根据指示信息的确定第一载波上的带宽部分的激活/去激活状态。
如此，在图4所示方案中，接入网设备向终端设备发送指示信息，通过指示信息指示载波上BWP的激活/去激活状态，以便终端设备根据该指示信息确定各个载波上BWP的激活/去激活状态，在激活BWP上监测PDCCH。如此，解决了如何确定载波上的BWP的激活/去激活状态的问题。
其中，在图4所示方案中的指示信息可以为下述(一)～(四)中的任一种形式：
(一)：指示信息包括第一比特图，第一比特图包括至少一个比特位，至少一个比特位与第一载波上的至少一个BWP一一对应，每个比特位的取值用于指示比特位对应的BWP的激活/去激活状态。
其中，该形式中，指示信息不仅包括第一比特图，还可以其他多个比特图，即该指示信息可以包括至少一个比特图，至少一个比特图与至少一个载波一一对应，每个比特图包括的至少一个比特位与该比特图对应的载波上的至少一个BWP一一对应。至少一个比特图与至少一个载波的对应关系可以由网络预配置给终端设备，如：接入网设备可以将下述对应关系配置给终端设备：比特图1对应载波1，比特图2对应载波2，比特图3对应载波3，以便终端设备获知哪个比特图对应哪个载波。
每个比特图中包含的比特位与该比特图对应的载波上的带宽部分的对应关系可以由网络预配置给终端设备，每个比特位可以携带1位比特的数值，如：可以用数字1来指示该比特位对应的带宽部分处于激活状态，即该带宽部分为激活BWP，用数字0来指示该比特位对应的带宽部分处于去激活状态，即该带宽部分为去激活BWP，还可以用比特位上的其他不同字符表示该比特位对应的带宽部分的激活/去激活状态，不予限制。例如，当某个比特图对应载波1，且该比特图中的比特位1与带宽部分1对应，比特位2与带宽部分2对应，且比特位1携带的数值为1，比特位2上的数值为0时，则指示比特位1对应的带宽部分1为激活BWP，比特位2对应的带宽部分2为去激活BWP。
例如，如图5a所示，包含N个载波，每个载波上都存在激活或未激活的带宽部分，则接入网设备向终端设备发送的指示信息中可以包含N个比特图，N个比特图与N个载波一一对应，每个比特图中的比特位与载波上的带宽部分对应，如：比特图1的第一个比特位与载波1上的BWP1对应，可以携带BWP1的激活/去激活信息(如该比特位为1，表示BWP1激活，该比特位0表示BWP1去激活)，第二个比特位与载波1上的BWP2对应，可以携带BWP2的激活/去激活信息(如该比特位为1，表示BWP2激活，该比特位0表示BWP2去激活)；比特图N的第一个比特位与载波N上 的BWPx对应，可以携带BWPx的激活/去激活信息(如该比特位为1，表示BWPx激活，该比特位0表示BWPx去激活)，第二个比特位与载波N上的BWPy对应，可以携带BWPy的激活/去激活信息(如该比特位为1，表示BWPy激活，该比特位0表示BWPy去激活)。如此，当终端设备接收到的指示信息中包含N个比特图时，可以根据每个比特图中与载波上的BWP对应的比特位的取值确定BWP的激活/去激活状态。
需要说明的是，每个比特图除包含用于指示带宽部分的激活/去激活状态的比特位之外，还可以包含携带其他信息的比特位，如图5a所示，还可以包含空白填充(padding)，不予限制。
(二)：指示信息包括一个比特图，比特图包括M个比特位，M个比特位与N个载波上的BWP一一对应，N个载波上的BWP的总数量为M，M为大于等于1的整数，N为大于等于1的整数，N个载波包括第一载波；指示信息中与第一载波上的BWP对应的比特位的取值用于指示第一载波上的BWP的激活/去激活状态。
例如，假设接入网设备为终端设备配置2个载波：载波1和载波2，载波1上包括3个BWP，载波2上包括2个BWP，在该实现方式中，指示信息可以为包括5个bit位的比特图，这5个bit位与载波1上的3个BWP和载波2上的2个BWP一一对应。如此，终端设备可以根据指示信息中与第一载波上的带宽部分对应的比特位来指示激活/去激活第一载波上的带宽部分。
其中，M个比特位与N个载波上的BWP的对应关系可以由网络预配置给终端设备。每个比特位可以携带1位比特的数值，如：可以用数字1来指示该比特位对应的带宽部分处于激活状态，用数字0来指示该比特位对应的带宽部分处于去激活状态，还可以用比特位上的其他不同字符表示该比特位对应的带宽部分的激活/去激活状态，不予限制。例如，当比特位1与载波1的带宽部分1对应，比特位2与载波2的带宽部分1对应，且比特位1携带的数值为1，比特位2上的数值为0时，则指示载波1的带宽部分1为激活BWP，载波2的带宽部分2为去激活BWP。
例如，如图5b所示，包含N个载波，每个载波上都存在至少一个激活或未激活的带宽部分，N个载波上的BWP的总数量为M，则接入网设备向终端设备发送的指示信息中可以包含1个比特图，该比特图可以包含M个比特位，该M个比特位与M个带宽部分对应，这M个带宽部分可以由N个载波上所有的BWP组成，如：比特位1与载波1的BWP1对应，当比特位为1，表示载波1的BWP1处于激活状态，为激活BWP，比特位为0表示载波1的BWP1处于去激活状态，为去激活BWP；第二个比特位与载波1的BWP2对应，当比特位为1，表示载波1的BWP2处于激活状态，为激活BWP，比特位为0表示载波1的BWP2处于去激活状态，为去激活BWP等等；第三个比特位与载波2的BWP1对应，当比特位为1，表示载波2的BWP1处于激活状态，为激活BWP，比特位为0表示载波2的BWP1处于去激活状态，为去激活BWP；……；最后一个比特位(第M位)与载波N的最后一个编号的BWP(图中BWPy)对应，当比特位为1，表示载波N的最后一个编号的BWP为激活BWP，比特位为0表示载波N的最后一个编号的BWP为去激活BWP。
可理解的是，上述比特图除包含用于指示激活/去激活带宽部分的比特位之外，还可以包含携带其他信息的比特位，如图5b所示，还可以包含padding，不予限制。
(三)：指示信息承载在第一载波上的下行物理信道的MAC CE中，指示信息携带的指示信息包括至少一个比特位，至少一个比特位与第一载波上的至少一个BWP对应，每个比特位的取值用于指示比特位对应的BWP的激活/去激活状态。
其中，上述至少一个比特位与第一载波上的至少一个带宽部分的对应关系可以由网络预配置给终端设备，每个比特位可以携带1位比特的数值，如：可以用数字1来指示该比特位对应的带宽部分处于激活状态，用数字0来指示该比特位对应的带宽部分处于去激活状态，还可以用比特位上的其他不同字符表示该比特位对应的带宽部分的激活/去激活状态，不予限制。例如，当比特位1与带宽部分1对应，比特位2与带宽部分2对应，且比特位1携带的数值为1，比特位2上的数值为0时，确定比特位1对应的带宽部分1处于激活状态，比特位2对应的带宽部分2处于去激活状态。
可选的，接入网设备向终端设备发送指示信息，包括：接入网设备在第一载波向终端设备发送下行物理信道，指示信息承载在下行物理信道的MAC CE中。
在接入网设备通过第一载波发送指示信息之前，所述方法还可以包括：
接入网设备在第二载波上向终端设备发送DCI；其中，DCI包括CIF，CIF用于指示第一载波，DCI用于指示在第一载波上调度下行物理信道。
在执行上述过程之前，若第一载波未处于激活状态，还需要执行激活第一载波的过程，如：可以通过其他激活载波携带的信息来指示激活第一载波。具体实现如下：
当第一载波未激活时，接入网设备在第二载波上向终端设备发送用于指示激活第一载波的信息，以便终端设备根据该信息激活第一载波，其中，该信息可以携带在第二载波上的MAC CE中。
不失一般性，本发明不排除使用其他的第一载波激活方式。
例如，假设第一载波为目标载波，如图5c所示，目标载波处于激活状态，且该目标载波包含BWPx和BWPy两个带宽部分，当接入网设备配置了目标载波上的带宽部分的激活/去激活状态后，接入网设备在处于激活状态的主载波上发送包含CIF的DCI，该CIF用于指示在目标载波上调度下行物理信道，接入网设备在目标载波的下行物理信道上发送指示信息，该指示信息包含两个与目标载波的带宽部分对应的比特位，第一个比特位与BWPx对应，可以携带BWPx的激活/去激活信息，第二个比特位与BWPy对应，可以携带BWPy的激活/去激活信息。
需要说明的是，上述指示信息除包含用于指示激活/去激活带宽部分的比特位之外，还可以包含携带其他信息的比特位，如图5c所示，还可以包含padding，不予限制。
(四)：指示信息包括第一载波的标识信息、以及第一载波上的BWP的标识信息；第一载波的标识信息用于标识第一载波，BWP的标识信息用于标识第一载波上的激活BWP。
其中，第一载波的标识信息用于标识第一载波，可以为第一载波的标识信息，如第一载波的编号，该编号可以为数字或者其他字母或者符号，不予限制。例如，第一载波的1的编号为1，则第一载波的标识信息为1。
带宽部分的标识信息用于标识带宽部分，可以为带宽部分的标识信息，如带宽部分的编号，该编号可以为数字或者其他字母或者符号，不予限制。例如，带宽部分的1的编号为1，则带宽部分的标识信息为1。
其中，在指示信息的该设计形式中，指示信息可以承载在处于激活状态的第一载波上向终端设备发送，也可以承载在第一载波之外的处于激活状态的其他载波向终端设备发送，不予限制。
例如，如图5d所示，指示信息包含载波N的标识信息，以及载波N上的带宽部分的标识信息，以指示激活载波N上的带宽部分，如：该指示信息中的指示信息包含载波1的编号1、以及载波1上的带宽部分1的编号A，则指示激活载波1上的带宽部分1，如此，当终端设备接收到该指示信息后，确定载波1上的带宽部分1处于激活状态，而载波1上剩余的带宽部分可能处于去激活状态，为去激活BWP。
需要说明的是，指示信息除包含载波N的标识信息，以及载波N上的带宽部分的标识信息之外，还可以包含携带其他信息的比特位，如：还可以包含padding，不予限制。
