具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***或5G***等。
示例性的，本申请实施例应用的通信***100如图1所示。该通信***100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM***或CDMA***中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land  Mobile Network，PLMN)中的网络设备等。
该通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信***(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G***或5G网络还可以称为新无线(New Radio，NR)***或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/***中具有通信功能的设备可称为通信设备。以图1示出的通信***100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信***100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为了能够提供更大的数据传输速率，提升用户体验，5G NR在4G基础上进一步增大了***带宽。在5G NR中，对于6GHz以下频段，单载波可以支持的最大带宽为100MHz；对于6GHz以上频段，单载波可以支持的最大带宽为400MHz。
与LTE***相同，5G NR也支持载波聚合(Carrier Aggregation，CA)技术。网络设备通过为终端设备配置多个服务小区，终端设备可以同时在这多个服务小区上进行数据的发送和接收，从而提升数据传输速率。
从另一方面来看，对于一个大的载波带宽，比如100HMz，终端设备需要使用的带宽往往非常有限，如果让终端设备始终在整个带宽上进行检测和测量，对终端设备功耗将带来极大的挑战，不利于终端设备的省电。因此，在5G NR中引入了带宽部分(BandWidth Part，BWP)的概念，即在整个大带宽的载波内划分出一部分连续的带宽给 终端设备进行数据收发。终端设备可与只需要在网络设备配置的这部分带宽内进行相关操作，从而起到终端设备节能的效果。
对于终端设备的每个服务小区，网络设备可以通过(Radio Resource Control，RRC)可以为终端设备在这个服务小区上配置一个或者多个BWP，可配置的最大BWP数目可选地可以为4。在每个时刻，终端设备可以在这个服务小区上只能有1个激活的下行(Downlink，DL)BWP和1个激活的上行(Uplink，UL)BWP，终端设备可以只能在激活的BWP上进行数据收发。
终端设备可以通过接收网络设备发送的物理下行控制信道(Physical Downlink Control Channel，PDCCH)来获知下行或上行调度信息，从而可以进一步完成业务数据的接收和发送。网络设备调度终端设备的时刻是不固定的，由于没有相关信令告知终端网络是否给该终端发送了PDCCH，终端设备需要盲检PDCCH。为了降低终端设备盲检的复杂度，需要限制盲检测PDCCH的集合。因此，可以引入搜索空间，即终端需要盲检的PDCCH资源集合。网络设备可以为终端的每个BWP配置一个或者多个PDCCH搜索空间，每个PDCCH搜索空间对应一个PDCCH监听周期。终端设备可以只在当前激活的BWP上监听PDCCH并进行数据收发。
在CA配置中，如果终端设备处于DRX激活期(非连续接收(Discontinuous Reception，DRX)Active Time)，那么终端设备可以盲检包括主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)在内的所有服务小区上的PDCCH，这会导致终端设备的PDCCH盲检开销增大，不利于终端设备省电。可以采用以下几种方式可以减少SCell上的PDCCH盲检开销：
由于SCell主要是在业务量大的时候用于offload大数据量，一种方式是，网络设备如果判断到数据量降低，网络设备可以利用提前激活一些SCell。但是，这种方式的缺点是，业务量的到达是随机的，重新激活SCell需要比较长的时延(比如40ms)，这样会对业务要求的吞吐量有影响。
另外一种方式是，可以采用唤醒信令(wake-up signalling，WUS)来指示在下一个DRX持续期(DRX onduration)期间，终端设备可以在哪些SCell上不需要盲检PDCCH，这种方式能灵活的控制终端设备在SCell上盲检行为，但是当业务量比较低的时候，会要求网络频繁的发送信令使得终端设备不去盲检SCell上的PDCCH。
图2是根据本申请实施例的无线通信方法200的示意性流程图。该方法200包括以下内容中的至少部分内容。
在210中，网络设备向终端设备发送下行动态信令，所述下行动态信令指示终端设备将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，或从第二BWP切换到第一BWP。
本申请实施例提到的下行动态信令可以是层1(L1)信令，也可以是层2(L2)信令。
本申请实施例提到的下行动态信令可以是下行控制信息(Downlink Control Information，DCI)，该DCI可以是终端设备盲检PDCCH得到的，该PDCCH可以是通过小区无线网络临时标识(Cell Radio Network Termorary Identity，C-RNTI)加扰的，也可以是通过配置调度(Configured Scheduling，CS)-RNTI(CS-RNTI)加扰的，也可以是通过一个新的RNTI加扰，例如，PS-RNTI。
本申请实施例提到的辅小区组包括可以一个或多个辅小区。本申请实施例中，辅小区的分组可以是RRC信令配置。
本申请实施例中，下行动态信令可以是通过主小区或主辅小区(PSCell)发送的。或者，在本申请实施例中，下行动态信令也可以是通过辅小区发送的。该辅小区可以属于上述至少一个辅小区组或多个辅小区。
可选地，在本申请实施例中，所述下行动态信令用于指示需要切换BWP的所述至少一个辅小区组或多个辅小区。也就是说下行动态信令可以具有信息域，该信息域可以指 示哪些辅小区组或辅小区可以需要进行BWP的切换。指示辅小区组需要切换BWP，则可以是该辅小区组内的所有辅小区均进行BWP的切换。
或者，在本申请实施例中，所述下行动态信令未指示需要切换BWP的所述至少一个辅小区组或多个辅小区；所述至少一个辅小区组或多个辅小区包括配置了所述第一BWP的辅小区。
也就是说，下行动态信令可以未指示哪些辅小区组或辅小区需要进行BWP切换，则终端设备可以根据哪些辅小区或辅小区组配置了特定的BWP(第一BWP或第二BWP)，从而对这些辅小区或辅小区组进行BWP的切换。
在本申请实施例中，终端设备可以根据辅小区或辅小区组的切换前的BWP是否是特定的BWP，而决定是否对这些辅小区或辅小区组进行BWP的切换。
或者，在本申请实施例中，终端设备可以根据辅小区或辅小区组是否配置了需要切换到的BWP，而决定是否对这些辅小区或辅小区进行BWP的切换。
可选地，在本申请实施例中，下行动态信令可以指示切换前的BWP是哪个BWP，则当前具有的BWP是下行动态信令指示的BWP的辅小区或辅小区组进行BWP的切换。
可选地，在本申请实施例中，下行动态信令可以指示切换后的BWP是哪些BWP，则辅小区或辅小区组可以将BWP切换到该指示的BWP。
当然，在本申请实施例中，下行动态信令即可以指示切换前的BWP，又可以指示切换后的BWP。
本申请实施例提到的BWP可以是下行BWP，也可以是上行BWP。
可选地，在本申请实施例中，所述下行动态信令为在非连续接收DRX激活期(DRX Active Time)内检测的下行动态信令。
可选地，在本申请实施例中，所述下行动态信令为在DRX持续定时器开启之前检测的。其中，所述下行动态信令还用于指示所述终端设备是否需要启动所述DRX持续定时器。可以借用是否启动DRX持续定时器的下行动态信令来指示进行BWP的切换，从而可以节省信令开销。
在220中，终端设备接收下行动态信令。
在230中，终端设备根据所述下行动态信令的指示，终端设备将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，或从第二BWP切换到第一BWP。在本申请实施例中，从第一BWP切换到第二BWP可以是指将终端设备的激活BWP从第一BWP切换为第二BWP。从第二BWP切换到第一BWP可以是指将终端设备的激活BWP从第二BWP切换为第一BWP
终端设备将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，或从第二BWP切换到第一BWP，意味着终端设备可以在切换后的BWP上进行通信，例如，如果BWP是下行BWP，则可以切换后的BWP上检测参考信号和/或PDCCH。如果BWP是上行BWP，则可以在切换后的BWP上发送物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和/或物理上行控制信道(Physical Uplink Control Channel，PUCCH)。
而对于网络设备而言，也将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，或从第二BWP切换到第一BWP，意味着网络设备可以在切换后的BWP上进行通信，例如，如果BWP是下行BWP，则可以在切换后的BWP上发送参考信号和/或PDCCH。如果BWP是上行BWP，则可以在切换后的BWP接收PUSCH和/或PUCCH。
可选地，在本申请实施例中，所述终端设备在第二BWP不盲检控制信道；和/或，在所述第二BWP传输数据时采用的多入多出(MIMO)层的层数和在所述第一BWP上传输数据时采用的MIMO层的层数不同；和/或，所述第二BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔大于或等于门限值以及所述第一BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔小于所述门限值；和/或， 第二BWP上配置的搜索空间的周期小于第一BWP上配置的搜索空间的周期。
具体地，终端设备在接收到下行动态信令之后，可以在第二BWP上不盲检控制信道(此处意味着该第二BWP未配置有搜索空间，或者虽配置有搜索空间，但并不对该搜索空间进行盲检)，从而可以节省终端设备的电量，则网络设备也可以在第二BWP上不针对终端设备发送控制信道，其中，终端设备可以根据终端设备的业务量，来确定是否发送下行动态信令，指示在第二BWP上不盲检PDCCH，此时第二BWP可以称为省电BWP。在本申请实施例中，在第二BWP上不盲检PDCCH的情况下，可以在第二BWP上检测下行参考信号。
可选地，在本申请实施例中，在所述第二BWP传输数据时采用的MIMO层的层数和在所述第一BWP上传输数据时采用的MIMO层的层数不同，例如，在第二BWP上采用的MIMO层的层数可以大于在第一BWP上采用的MIMO的层数，或者，在第一BWP上采用的MIMO层的层数可以小区第一BWP上采用的MIMO层数(此时，第二BWP可以是称为省电BWP)。
可选地，在本申请实施例中，所述第二BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔大于或等于门限值以及所述第一BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔小于所述门限值。此处提到的预设值可以是预设在终端设备上，或者，也可以是由网络设备配置给终端设备的。
可选地，在本申请实施例中，网络设备可以为终端设备的每个服务小区或服务小区组配置一个或多个下行BWP(也可以是上行BWP)(例如，5个)，在配置的BWP中，可以包括一个第二BWP。或者，可以配置一个或多个第一BWP(例如，可以为4个)，以及一个第二BWP。
在本申请实施例中，从第一BWP切换到第二BWP可以是基于下行动态信令指示的，以及从第二BWP切换到第一BWP或其他的BWP也可以是基于下行动态信令指示的。
以上提到了可以基于下行动态信令的指示，对至少一个辅小区组或多个辅小区进行BWP的切换，但是本申请实施例并不限于此，在本申请实施例，还可以基于RRC信令的指示、由于定时器超时或者随机接入初始化引起BWP的切换。
作为示例性地，在本申请实施例中，每次终端设备在切换完多个辅小区或至少一个辅小区组的BWP之后，可以启动定时器，在定时器超时时，可以再次启动定时器，每次启动的定时器的时长可以相同，也可以不相同，可以与当前被切换到的BWP有关。
作为示例性地，下行动态信令和定时器可以结合用于触发BWP的切换。终端设备接收到下行动态信令，基于下行动态信令的指示，终端设备将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP。并且，终端设备可以针对每个辅小区或辅小区组均启动定时器(不同的辅小区或辅小区组启动的定时器的时长可以相同，也可以不相同)，该定时器的作用是在确定终端设备在切换后的第二BWP上的停留时间。其中，该定时器的时长可以是RRC信令配置的，也可以是下行动态信令指示的。
当存在定时器超时时，可以将该定时器对应的辅小区或辅小区组的BWP从第二BWP切换回第一BWP或切换到其他的BWP(例如，初始BWP或默认BWP)。
如果在定时器的运行期间，再次收到下行动态信令，该下行动态信令指示将下行BWP切换到第二BWP，则终端设备可以重新启动定时器。
可选地，本申请实施例提到的定时器可以是DRX非激活定时器(drx-InactivityTimer)。
此时，下行动态信令可以是在DRX激活器内检测到的。
具体地，终端设备也可以在DRX Active Time盲检PDCCH从而获得该DCI，该PDCCH用C-RNTI或者CS-RNTI加扰。该PDCCH可以指示多个或者至少一个组SCell上的下行激活BWP切换到省电(Power Saving，PS)BWP(PS BWP)；
终端设备收到该PDCCH，可以启动或者重新启动drx-InactivityTimer终端设备在该 drx-InactivityTimer运行期间，终端设备保持在PS BWP上；当drx-InactivityTimer超时时，终端设备切换到之前激活的BWP，或者是初始BWP，或者是默认BWP。
应理解，在本申请实施例，每个辅小区组或辅小区可以分别对应于一个定时器，也可以是所有的辅小区组或辅小区对应于一个定时器。
可选地，在本申请实施例中，从第一BWP切换到第二BWP可以是基于下行动态信令指示的，终端设备可以将辅小区或辅小区组保持在第二BWP上，一直到下次需要再次检测动态信令，如果检测到下行动态信令，如果该信令指示将至少一个辅小区组或多个辅小区的BWP切换到第二BWP，则可以不进行BWP的切换，终端设备仍然保持在该第二BWP上。如果终端设备没有检测到下行动态信令，则终端设备可以将至少一个辅小区组或多个辅小区的BWP从第二BWP切换到第一BWP，或者另一个BWP，例如，可以初始BWP或者默认BWP。
具体地，终端设备在DRX周期的drx-ondurationTimer启动之前的某一个时间段内，终端设备检测到动态信令，且该动态信令指示终端设备切换到PS BWP，则终端仍然保持在该PS BWP；终端设备保持在该PS BWP直到下一个DRX周期；如果在下一个DRX周期的drx-ondurationTimer启动之前的某一个时间段内，UE检测到动态信令，且该动态信令指示终端设备切换到PS BWP，则UE仍然保持在该PS BWP；如果在下一个DRX终端设备的drx-ondurationTimer启动之前的某一个时间段内，终端设备没有检测到动态信令，则终端设备切换到一个下行BWP，该下行BWP可以是之前激活的下行BWP，也可以是初始BWP或者默认下行BWP。
可选地，在本申请实施例中，终端设备接收到一个下行动态信令，指示将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，则终端设备将至少一个辅小区组或多个辅小区的BWP从第一BWP切换到第二BWP，终端设备再次接收到一个下行动态信令，指示将至少一个辅小区组或多个辅小区的BWP从第二BWP切换回第一BWP，则终端设备将至少一个辅小区组或多个辅小区的BWP从第二BWP切换到第一BWP。
具体地，终端设备基于动态信令，将至少一个辅小区组或多个辅小区的当前激活DL BWP切换到PS BWP后，终端设备保持在该PS BWP上，终端设备保持在该PS BWP，直到收到另外一个动态信令，该动态信令指示UE切换到非PS BWP；该另外一个动态信令可以与切换终端设备到PS BWP的动态信令相同，也可以不同；另外一个动态信令可以指示终端设备在某一个/组或者多个/组SCell上切换到一个非PS BWP。该非PS BWP可以由该另外一个动态信令指示，也可以是网络预先配置。
为了更加清楚地理解本申请，以下结合图3-6对本申请实施例进行说明。
如图3所示，UE被配置了三个SCell，其中在辅小区(SCell)组1和辅小区(SCell)2上，网络设备给UE配置了PS BWP。在SCell 3上网络设备没有给UE配置PS BWP。
在一种方案中，UE在PCell或者PSCell上收到动态指示信令，UE将辅小区组1和辅小区组2上的当前下行激活BWP切换到预先配置的PS BWP；UE在drx-ondurationTimer启动之前盲检PDCCH，该PDCCH既指示UE是否要启动drx-ondurationTimer，同时还可以指示UE是否要将SCell上当前激活的下行BWP切换到PS BWP。如图4所示，在第一个DRX周期，UE启动drx-ondurationTimer之前盲检PDCCH，该PDCCH指示UE启动drx-ondurationTimer，同时该PDCCH也指示SCell上的下行激活BWP切换到PS BWP；如图5所示，在辅小区组1或者辅小区组2上，当UE切换到PS BWP，UE启动一个定时器，在该定时器期间，UE保持在PS BWP，当定时器超时，UE可以切换到之前激活的下行BWP，也可以切换到初始或者默认BWP。假设PS BWP的索引为1，之前激活的DL BWP索引为2，初始或者默认BWP为#3，则UE在定时器超时时，可以切换到#2BWP，也可以到#3BWP。需要注意的是，初始或者默认BWP的索引可以不同。
在另一种方案中，如图6所示，在辅小区组1或者辅小区组2上，根据PDCCH指示，UE把辅小区组1和辅小区组2上的DL BWP切换到PS BWP，UE保持在该PS BWP。当收到PDCCH时，该PDCCH可以指示UE在辅小区组1和辅小区组2上将PS BWP切换至另外一个BWP。
可选地，在本申请实施例中，可以根据业务量的变化，调整至少一个辅小区组或多个辅小区的BWP，从而可以避免功率损耗。
因此，在本申请实施例中，响应于下行动态信令的指示，终端设备可以切换至少一个辅小区组或多个辅小区的BWP，可以实现灵活调整BWP，并且收到下行动态信令之后，切换的为至少一个辅小区组或多个辅小区的BWP，可以节省信令开销。

在本申请实施例中，终端设备可以根据辅小区或辅小区组的调整前的BWP配置是否 是特定的BWP配置，而决定是否对这些辅小区或辅小区组进行BWP的配置的调整。
或者，在本申请实施例中，终端设备可以根据辅小区或辅小区组的BWP配置是否是特定的BWP配置，而决定是否对这些辅小区或辅小区进行BWP的配置的调整。

调整前的所述配置与调整后的所述配置在以下方面中的至少一种不同：在所述BWP上传输数据时采用的MIMO层的层数、所述BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔是否大于或等于门限值、是否在所述BWP上进行PDCCH的搜索。
可选地，在本申请实施例BWP可以具有两种配置，在第二种配置下，在所述BWP上传输数据所采用的MIMO层的层数低于第一种配置。
在第二种配置下，所述BWP上发送的控制信道与所述控制信道调度的数据信道之间的时间间隔小于门限值，在第一种配置下，该时间间隔则大于门限值。

在本申请实施例中，从第一种配置调整到第二种配置可以是基于下行动态信令指示的，以及从第二种配置调整到第一种配置或其他的配置也可以是基于下行动态信令指示的。
以上提到了可以基于下行动态信令的指示，对至少一个辅小区组或辅小区进行BWP的配置的调整，但是本申请实施例并不限于此，在本申请实施例，还可以基于RRC信令的指示、由于定时器超时或者随机接入初始化引起BWP的配置的调整。
作为示例性地，在本申请实施例中，每次终端设备在调整完至少一个辅小区或至少一个辅小区组的BWP的配置之后，可以启动定时器，在定时器超时时，可以再次启动定时器，每次启动的定时器的时长可以相同，也可以不相同，可以与当前被调整到的配置有关。
作为示例性地，下行动态信令和定时器可以结合用于触发BWP的调整。终端设备接收到下行动态信令，基于下行动态信令的指示，终端设备将至少一个辅小区组或多个辅小区的BWP从第一种配置调整到第二种配置。并且，终端设备可以针对每个辅小区或辅小区组均启动定时器(不同的辅小区或辅小区组启动的定时器的时长可以相同，也可以不相同)，该定时器的作用是在确定终端设备在调整后的第二种配置上的停留时间。其中，该定时器的时长可以是RRC信令配置的，也可以是下行动态信令指示的。
