具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、新无线(new radio，NR)通信系统、下一代(next generation,NG)通信系统以及未来的移动通信系统等。
本申请实施例中的终端设备可以指用户设备、接入终端、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。终端设备还可以是蜂窝电话、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、个人数字助理(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，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备以及5G网络中的新一代基站(new generation Node B,gNodeB)，未来演进的PLMN中的基站等，本申请实施例并不限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
为了便于理解，首先介绍几个本申请实施例中涉及的概念。
带宽部分(bandwidth part,BWP)，一个小区中的全部带宽的子集可以称为BWP。或者小区载波的部分可以称为BWP。BWP可以指网络设备分配给终端设备的载波带宽内的部分频域资源。BWP的大小可以小于或等于终端设备的带宽能力，或者说小于或等于终端设备支持的最大带宽。且BWP可以是连续的频域资源，例如，BWP可以包括连续的多个子载波，再例如，BWP可以包括多个连续的PRB(physical resource block，物理资源块)。BWP也可以是不连续的频域资源。其中连续的频域资源，有利于降低资源分配的复杂度，不连续的频域资源有利于离散资源的利用。终端可以支持多个BWP，即网络设备可以为终端配置多个BWP，当配置多个BWP时，BWP之间可以重叠，BWP之间也可以不重叠。此外，不同BWP包括的频域资源的子载波间隔可以相同，也可以不同。
例如，图1示出了本申请实施例的小区中的BWP的分布示意图。如图1所示，终端设备在一个小区上，可以基于带宽自适应性，仅仅利用整个小区的部分带宽与网络设备进行通信。网络设备将告知终端设备当前哪个BWP处于激活态。终端设备可以仅支持一个BWP。例如，如图1所示，小区中的带宽可以包括BWP 1、BWP 2、BWP 3等。BWP 1的带宽为40兆赫兹(MHz)，子载波间隔为15Hz；BWP 2的带宽为10MHz，带宽为15kHz；BWP3的带宽为20MHz，子载波间隔为60kHz。在高频下，一个小区载波带宽可以达到几百兆赫兹，终端设备可以不基于小区带宽，而是基于BWP实现与网络设备的通信，从而可以节省终端设备的功耗，同时也增强了调度的灵活性。
信道状态信息(channel state information,CSI)：CSI可以是终端设备向网络设备发送 的用于指示下行信道的信道质量的信息。CSI可以是根据下行参考信号获取的。CSI包括以下至少一种：信道质量指示(channel quality indicator,CQI)，用于网络设备在后续调度采用何种编码方式；秩指示(rank indication,RI)，用于指示PDSCH的有效的数据层数，以及用于通知网络设备终端设备当前可以支持的码字数；预编码矩阵指示(precoding matrix indicator,PMI)，用于指示码本集合的索引(index)；预编码类型指示(precoding type indicator,PTI)，用于指示预编码类型；信道状态信息参考信号资源指示(CSI reference signal resource indicator,CRI)，用于指示CSI-RS资源；参考信号接收功率(reference signal received power,RSRP)，用于指示无线信号强度，即指示在某个符号内承载参考信号的所有资源单元(resource element,RE)上接收到的信号功率的平均值；信道状态信息参考信号(CSI reference signal,CSI-RS)：用于信道估计和CQI反馈。
空闲态：处于空闲态下的终端设备不保存终端设备的上下文信息，并在该状态下执行PLMN选择，小区重选，接收来自于核心网的寻呼(paging)消息。此时，核心网保留终端设备的上下文信息。
非激活态：处于非激活态下的终端设备将保存终端设备的上下文信息，并在该状态下执行PLMN选择，小区重选，接收来自于无线接入网的寻呼消息。此时，接入网和核心网保留终端设备的上下文信息。上述无线接入网可以是下一代无线接入网(next generation radio access network,NG-RAN)。
连接态：或者也可以称为激活态(activation)，处于连接态的终端设备与接入网设备、核心网设备存在控制面和用户面连接。接入网设备、核心网设备和终端设备保存终端设备的上下文信息，接入网设备控制终端设备的移动性。
同步序列或物理广播信道块(synchronization sequence/physical broadcast channel block,SSB)：可以包括主同步信号、辅助同步信号、物理层广播信道等。
图2是本申请实施例的可能的应用场景示意图。如图2所示，该应用场景可以包括终端设备和网络设备。关于终端设备和网络设备的具体描述可以参见前文的相关描述。作为一个示例，所述终端设备可以是移动终端，所述网络设备可以是接入网设备。如图2所示，终端设备可以通过网络设备接入网络，终端设备和网络设备之间可以通过无线链路进行通信。
图3是本申请实施例的双链接场景的示意性架构图。如图3所示，双链接场景中通常可以包括主节点(master node,MN)和辅节点(secondary node,SN)。其中上述主节点或辅节点也可以分别称为主基站和辅基站。或者，也可以分别称为主网络设备和辅网络设备，其中，主基站中可以包括主小区和辅小区，辅基站中也可以包括主小区和辅小区，辅助基站中的主小区还可以称为主辅小区(primary secondary cell,PScell)。双链接场景中，MN和SN可以共同服务于终端设备。或者说，针对于终端设备与核心网建立的同一会话，主基站和辅基站可以与终端设备进行数据传输。在一种可能的场景中，主基站可以负责与终端设备之间的控制面信令流程以及用户面数据传输，而辅基站只需负责与终端设备之间的用户面数据传输。即主基站可以和终端设备之间建立数据资源承载(data resource bearer,DRB)以及信令资源承载(signal resource bearer,SRB)，辅基站只需和终端设备之间建立DRB。或者，在另一种可能的场景中，主基站和辅基站的每个可以负责与终端设备之间的控制面传输以及用户面数据传输。即主基站可以与终端设备之间建立DRB以及SRB，辅 基站也可以与终端设备之间建立DRB以及SRB。
图4示出了本申请实施例的载波聚合场景。载波聚合是指将两个或以上的成员载波(component carrier,CC)聚合在一起传输数据，以实现更大的传输带宽。终端设备可以根据自己的能力大小确定最多可以同时利用几个载波进行上下行传输。CA功能可以支持连续或非连续载波聚合，以及支持频段内或跨频段载波聚合。终端设备可以和单个网络设备之间使用载波聚合进行数据传输。或者，终端设备也可以和多个网络设备之间使用载波聚合进行数据传输。后者的一种典型实现方式是将一个宏基站的载波和若干个微基站的载波聚合在一起，微基站需要和宏基站通过回程链路连接在一起，并且与宏基站进行严格的系统时间同步。
载波聚合与双链接技术的共同之处在于终端设备都是通过多个载波与一个或多个网络设备进行数据传输。其不同之处在于载波聚合中多个载波的调度都由一个网络设备或该网络设备的调度器完成，而在双链接场景中，主网络设备与辅网络设备的调度器分别管理各自网络设备上的载波，所以需要相互进行协调。其中，上述调度器的功能可以是由网络设备的处理器执行的功能实体。在一种示例中，载波聚合场景在较低层协议上管理资源，用户数据传输时延较低。双链接场景在较高层协议上管理资源，用户数据传输时延较高。载波聚合与双链接技术还存在其他区别之处，此处不再一一赘述。
图5是本申请实施例的用于小区或波束测量的方法的示意性流程图。如图5所示，图5的方法包括：

可选地，在高频场景下，网络设备可以采用波束成型技术，形成具有指向性的波束。在这种情形下，网络设备使用多个不同指向的波束才能完全覆盖小区。因此一个小区中可以包括多个波束。所述小区测量可以指对小区中包括的至少一个波束的测量结果进行平均之后得到的测量结果。所述波束测量可以是小区中的一个或多个波束的各自的测量结果。例如，终端设备可以测量小区中信号质量高的若干个波束，并获取各个波束的测量结果。
可选地，本申请实施例的方法可以应用于采用波束成型技术的高频场景，也可以应用于中低频通信的场景。
需要说明的是，本申请实施例中的小区或波束测量可以包括仅有小区测量的情况，或包括仅有波束测量的情况，或者包括小区测量和波束测量均存在的情况。其中波束测量可以指对小区中包括的部分或全部波束进行测量。

在一个示例中，所述第一信息可以承载于RRC消息中。例如，上述第一信息可以承载于RRC连接释放(RRC connection release)消息中，其中，所述RRC连接释放消息用于指示终端设备离开连接态。例如，终端设备从连接态转移到空闲态或非激活态的情况下，网络设备向终端设备发送所述RRC连接释放消息，以指示终端设备从连接态转移到空闲态或者非激活态。在另一个示例中，所述第一信息可以承载于RRC恢复(RRC resume)消息中，所述RRC恢复消息可以用于指示恢复所述终端设备与网络设备之间的RRC连接。在又一个示例中，所述第一信息也可以承载于RRC重建(RRC reestablishment)消息中，所述RRC重建消息可以用于指示重建所述终端设备与网络设备之间的RRC连接。或者，所述第一信息也可以承载于其他类型的RRC消息中。
可选地，所述第一信息还可以承载于广播消息中。
S502、所述终端设备根据所述第一信息，向所述网络设备发送所述小区测量或波束测量的测量结果，相应地，网络设备接收所述小区测量或波束测量的测量结果。
可选地，终端设备可以在连接态时向网络设备发送所述小区测量或波束测量的测量结果。例如，终端设备可以根据所述第一信息，在空闲态或非激活态时进行上述小区测量或波束测量，并在进入连接态之后，向网络设备发送所述小区测量或波束测量的结果。从而终端设备可以在进入连接态之后快速向网络设备上报小区或波束的测量结果，以便于网络设备尽快为终端设备建立辅小区，从而减少了建立辅小区的时延，提高了通信效率。
可选地，所述小区测量或波束测量的结果可以称为小区或波束测量结果。该小区或波束测量结果可以承载于RRC消息中。例如，若所述终端设备从非激活态转移到连接态，则所述小区或波束测量的测量结果可以承载于RRC恢复完成(RRC resume complete)消息中。其中，所述RRC恢复完成消息用于指示所述终端设备已从非激活态转移到连接态。或者，所述小区或波束测量的测量结果也可以承载于其他RRC消息中，例如，当终端设备执行RRC连接重建时，所述小区或波束测量的测量结果可以承载于RRC重建完成(RRC reestablishment complete)消息中，或者也可以承载于其他RRC消息中，本申请实施例对此不作限定。
可选地，所述RRC恢复完成消息可以承载所述小区或波束测量的部分或全部测量结果。类似地，所述RRC重建完成消息也可以承载所述小区或波束测量的部分或全部测量结果。

在本申请实施例中，终端设备进行小区或者波束测量的检测信号可以包括SSB和/或CSI-RS，从而提高了小区或者波束检测的效率。
在本申请实施例中，终端设备在处于空闲态或非激活态时进行小区或波束测量，以便于在终端设备进入连接态之后，能够快速向网络设备上报小区或波束测量结果，从而网络设备可以根据该小区或波束测量结果，快速地为终端设备建立一个或多个辅小区，以减少建立辅小区的时延，提高通信效率。例如，网络设备可以根据小区或波束测量结果为终端设备接入一个或多个辅小区分配随机接入资源，从而可以减少建立辅小区的时延，提高随机接入成功率。
例如，在双链接场景下，终端设备在处于空闲态或非激活态时进行小区测量，并在终端设备进入连接态后，向网络设备发送小区或波束测量结果，从而网络设备可以根据小区或波束测量结果，快速地为终端设备建立辅助基站，可以减少建立辅助基站的时延，提高通信效率。其中，上述双链接场景下为终端设备建立的辅助基站可以包括建立主辅小区或者辅小区。
可选地，上述测量参数可包括与SSB相关的测量信息，例如，测量参数可以包括以下至少一项：

可选地，网络设备可以采用显示或隐式的方式指示上述优先级信息。例如，上述测量参数还可以包括以下描述的测量小区列表、测量波束列表、SSB列表、CSI-RS列表和区域列表。上述小区优先级信息可以承载于测量小区列表中。所述SSB优先级信息可以承载于SSB列表中、上述CSI-RS优先级信息可以承载于CSI-RS列表中，上述区域优先级信息可以承载于有效区域列表中。
测量小区列表可以是物理小区标识(physical cell identifier,PCI)列表，用于指定终端设备进行小区测量。可选地，在测量小区列表中，可以指示小区的优先级，从而终端设备在上报测量结果时，可以优先上报高优先级的小区的测量结果。其中，可以采用显式或隐式的方式指示小区的优先级。例如，在一个示例中，可以明确指示该测量小区列表中，哪 个或哪些小区为高优先级的小区，即上述第一小区。在另一个示例中，可以在测量小区列表指示小区的优先级顺序，例如，可以根据优先级从高到低排列小区列表，或者，也可以根据优先级从低到高排列小区列表。
SSB列表中可以指示SSB的优先级，从而终端设备在上报测量结果时，可以优先上报高优先级的SSB的测量结果。例如，在一个示例中，可明确指示该SSB列表中，哪个或哪些SSB为高优先级的SSB，即上述第一SSB。在另一个示例中，可以在SSB列表中指示SSB的优先级顺序，例如，可以根据优先级从高到低排列SSB列表，或者，也可以根据优先级从低到高排列小区列表。

可选地，上述测量参数还可以包括：测量持续时间(duration)、测量周期、层3(layer3,L3)滤波系数等。上述测量周期例如可以是SMTC1或者SMTC2的倍数，可以有效的降低处于空闲态和/或非激活态中的终端设备的测量功耗。另外，由于终端设备需要在进行L3滤波之后，再向网络设备发送小区测量的测量结果。若L3滤波的时间较长，则终端设备上报给网络设备的测量结果不能准确的反映终端设备状态转换前的测量结果。其中，上述状态转换是指终端设备由空闲态或非激活态转移到连接态。因此，网络设备可以配置终端设备上报该测量结果的测量时间。例如，可以上报该测量结果是终端设备在状态转换前多长时间的测量结果。例如，5分钟或10分钟前。可选地，为了终端设备进行快速地小区测量，网络设备可以为终端设备配置L3滤波周期。
可选地，终端设备还可以接收来自网络设备的第二信息，相应地，网络设备发送所述第二信息，所述第二信息指示允许终端设备在RRC恢复完成消息中上报所述小区或者波束测量的测量结果。或者，上述第二信息也可以指示不允许终端设备在RRC恢复完成消 息中上报所述小区或波束测量的测量结果。终端设备可以根据所述第二信息，确定是否在RRC恢复完成消息中上报所述小区测量的测量结果。或者，第二信息也可以指示是否允许终端设备在其他RRC消息中上报所述小区或波束测量的测量结果，例如，第二信息可以指示在RRC重建完成消息中发送所述小区或波束测量的测量结果。
可选地，终端设备可以根据第二信息的指示，确定是否在RRC恢复完成消息中上报小区或波束测量的测量结果。可选地，终端设备可以在RRC恢复完成消息中持续上报小区或波束测量结果。

为了服务小区快速地转移到激活态，本申请实施例定义了服务小区的休眠态(dormant)。其中，服务小区可以包括主小区和/或辅小区，其中该服务小区的状态是针对终端设备来说的。即该服务小区本身可以一直处于工作状态，但是，对于不同的终端设备而言，该服务小区可以处于不同的状态。例如，对于第一终端设备，该服务小区可以处于激活态，对于第二终端设备，该服务小区可以处于休眠态。例如，当服务小区对于第一终端设备处于休眠态时，第一终端设备将不接收服务小区对应的物理下行控制信道(physical downlink control channel,PDCCH)或者物理下行共享信道(physical downlink shared channel,PDSCH)，也不能进行上行传输，但是在服务小区对于第一终端设备处于休眠态时，第一终端设备可以执行CSI测量，以便于服务小区可以快速转移到激活态。
在本申请实施例中，服务小区中可以包括一个或多个BWP，其中BWP可以指一个服务小区中的所有带宽的一个子集。本申请实施例提供了一种基于BWP进行通信的方法。其具体涉及了在BWP的休眠态、BWP的激活态、BWP的去激活态下进行通信的方法。需要说明的是，上述BWP的各个状态是针对终端设备而言的。例如，同一BWP可以相对于一个终端设备为休眠态，而相对于另一个终端设备为激活态。
图7是本申请实施例的BWP的状态转换示意图。如图7所示，BWP可以由休眠态转移到去激活态或者激活态，或者也可以由激活态转移到休眠态或去激活态，或者由去激活态转移到激活态，或者由去激活态转移到休眠态。BWP在处于激活态或休眠态时可以不 进行数据调度，而在处于激活态时可进行数据调度。其中，BWP在处于休眠态时需上报BWP的CSI，而BWP在处于去激活态时可以不上报BWP的CSI，因此，相比于休眠态，BWP处于去激活态更节省终端设备的功耗。
可选地，BWP为休眠态的情况下，终端设备可以上报所述BWP的CSI，终端设备还可以基于该BWP执行以下操作中的至少一项：不通过所述BWP接收PDCCH；不通过所述BWP发送探测参考信号(sounding reference signal,SRS)；不通过所述BWP发送物理上行共享信道(physical uplink shared channel,PUSCH)的数据；不通过所述BWP发送随机接入的前导信号；不监听跨载波调度所述BWP的PDCCH；不通过所述BWP发送物理上行控制信道(physical uplink control channel,PUCCH)。换句话说，BWP为休眠态时，终端设备可以只上报所述BWP的CSI。例如，终端设备可以测量处于休眠态的BWP的参考信号，例如，SSB或CSI-RS，得到测量结果，并上报所述BWP的CSI。
在BWP为去激活态的情况下，终端设备可以基于该BWP执行以下操作中的至少一项：不上报所述BWP的CSI；不通过所述BWP接收PDCCH；不通过所述BWP发送SRS；不通过所述BWP发送PUSCH的数据；不通过所述BWP发送随机接入的前导信号；不监听跨载波调度所述BWP的PDCCH；不通过所述BWP发送PUCCH。换句话说，BWP为去激活态时，对终端设备来说，该BWP可以是不可见的。
在BWP为激活态的情况下，终端设备可以基于该BWP执行以下操作中的至少一项：上报所述BWP的CSI；通过所述BWP接收PDCCH；通过所述BWP发送SRS；通过所述BWP发送PUSCH的数据；通过所述BWP发送随机接入的前导信号；监听跨载波调度所述BWP的PDCCH；通过所述BWP发送PUCCH。
图8还示出了本申请实施例提供的一种通信方法，如图8所示，该通信方法包括：
S801、终端设备确定服务小区的BWP为休眠态。
其中，上述服务小区可以是主小区，也可以是辅小区。上述休眠态的BWP可以是所述服务小区中的部分BWP，也可以是所述服务小区的全部BWP。上述休眠态的BWP可以是一个BWP，也可以是多个BWP。
S802、在所述BWP为休眠态的情况下，所述终端设备上报所述BWP的CSI，相应地，网络设备接收所述BWP的CSI，所述终端设备还执行以下操作中的至少一项：不通过所述BWP接收PDCCH；不通过所述BWP发送SRS；不通过所述BWP发送PUSCH的数据；不通过所述BWP发送随机接入的前导信号；不监听跨载波调度所述BWP的PDCCH；不通过所述BWP发送PUCCH。
可选地，所述终端设备可以使用其他处于激活态的BWP上报所述休眠态的BWP。可选地，终端设备可以通过专用小区(special cell,SpCell)或者PUCCH辅小区上报所述CSI。可选地，可以由网络设备配置上报CSI所使用的资源。例如，所述SpCell可以是载波聚合场景下的主小区，或者可以是双链接场景中的主小区或主辅小区。
可选地，上述跨载波调度，可以指承载于第一载波上的控制信令可用于指示调度第二载波上的数据。或者说，第一小区的控制信令用于调度第二小区中的数据。通常情况下，一个小区可以包括至少一个下行载波，可选地，一个小区还可以包括至少一个上行载波，一个载波可以包括一个或多个BWP。例如，若第一BWP上的控制信令用于调度第二BWP上的数据，且第一BWP和第二BWP分别属于不同的载波，则为跨载波调度。若第二BWP 处于休眠态，则终端设备可以不监听跨载波调度第二BWP的PDCCH，即不监听第一BWP上的PDCCH。
可选地，CSI测量可包括CQI测量。对于处于休眠态的辅小区，网络设备可以为终端设备配置对应的CQI测量参数。
对于周期性(periodic)的CQI报告和半持续性(semi-persistent)的CQI报告，该CQI测量参数可以包括CQI报告的汇报周期和偏移。该CQI测量参数还可以包括：宽带CQI测量指示、一个或多个窄带CAI测量指示、一个或多个窄带CQI汇报指示、CQI表格(CQI table)等。
一个服务小区可以支持一个或多个BWP，其中BWP为一个小区中全部带宽的一个子集。若一个服务小区内的所有BWP均为休眠态，则所述服务小区为休眠态。若一个服务小区内的一部分BWP为休眠态，剩余的BWP为去激活态，则所述服务小区BWP为休眠态。若一个服务小区中的一部分BWP为激活态，则所述服务小区为激活态。
在本申请实施例中，终端设备在BWP为休眠态的情况下，可以基于BWP上报CSI，由于终端设备可以向网络设备上报处于休眠态的BWP的CSI，因而在BWP转移到激活态之后，网络设备可以根据之前接收的CSI，与终端设备快速地进行基于BWP的有效的数据调度。
可选地，所述终端设备可以采用多种方式确定服务小区的BWP为休眠态。
例如，在一种方式中，所述终端设备可以接收来自网络设备的第一指示信息，相应地，所述网络设备发送所述第一指示信息，所述第一指示信息用于指示所述BWP配置为休眠态。所述终端设备在接收到所述第一指示信息之后，可以确定所述BWP为休眠态。又例如，可选地，所述第一指示信息包括所述BWP的标识。
在一个具体示例中，网络设备可以向终端设备发送所述第一指示信息，所述第一指示信息包括上述一个或多个BWP的标识，所述第一指示信息还可以指示所述终端设备基于一个或多个BWP进行CSI的测量。
可选地，所述第一指示信息可以承载于下行控制信息(downlink control information,DCI)，或者，所述第一指示信息可以承载于辅小区添加(secondary cell addition)信息中，所述辅小区添加消息用于指示添加辅小区，或者，所述第一指示信息可以承载于主辅小区添加(primary secondary cell addition)信息中，所述主辅小区添加消息用于指示添加主辅小区，或者，所述第一指示信息可以承载于切换命令中。或者，第一指示信息可以承载于RRC信令中或MAC控制元素(control element，CE)中。
又例如，在另一种方式中，所述终端设备也可以根据定时器确定所述服务小区的BWP为休眠态。例如，所述终端设备可以接收来自网络设备的第一激活信息，相应地，所述网络设备向所述终端设备发送所述第一激活信息，所述第一激活信息用于指示所述BWP配置为激活状态。在接收到所述第一激活信息之后，所述终端设备可以启动第一定时器；其中，在所述终端设备每进行一次数据调度的情况下，所述终端设备启动或重启所述第一定时器。在所述第一定时器超时的情况下，所述终端设备确定所述BWP为休眠态。
换句话说，终端设备可以在所述BWP进入激活态之后，启动第一定时器，并在第一定时器超时的情况下，确定所述BWP为休眠态。采用这种方式可以无需接收网络设备的指示信息，因此可以节约信令开销。另外，在第一定时器启动后，若终端设备进行了数据 调度，则需要重启或启动第一定时器。例如，若终端设备从激活态的BWP接收到小区无线网络临时标识(cell radio network temporary identifier,C-RNTI)，配置调度无线网络临时标识(configured scheduling radio network temporary identifier,CS-RNTI)加扰的PDCCH，则需要重启或启动该BWP第一定时器。
其中，作为一个示例，本申请中的数据调度，可以包括以下任意一种情形：在激活态的BWP接收到通过C-RNTI或CS-RNTI加扰的PDCCH，该PDCCH用于指示下行链路分配或者上行链路授权；在配置的上行链路授权中发送MAC协议数据单元(protocol data unit,PDU)，或者在配置的下行链路分配中接收MAC PDU；没有与服务小区相关的正在进行的随机接入过程；在接收到通过C-RNTI的加扰PDCCH时，成功完成与该服务小区相关联的正在进行的随机接入过程。
此外，所述终端设备可以在接收所述第一激活信息之后，立即启动所述第一定时器，或者也可以在等待一段时间之后，启动所述第一定时器，本申请对此不作限定。可选地，所述第一定时器的时长可以是网络设备配置的。例如，网络设备可以向所述终端设备发送第二指示信息，所述第二指示信息用于指示所述第一定时器的时长。可选地，每个BWP可以对应一个第一定时器。若存在多个BWP，则可以配置与多个BWP一一对应的第一定时器。
可选地，所述第一激活信息可以包括两种类型，第一种类型是用于激活小区的激活命令，所述激活的小区为BWP所在的小区，或者第二种类型可以是用于激活BWP的激活命令。
例如，上述第一激活信息可以是网络设备发送的小区激活命令(cell activation command)，以指示服务小区中处于休眠态的全部或部分BWP转移到激活态的BWP，以便于进行调度。该第一激活信息可以承载于媒体接入控制控制元素(MAC control element,MAC CE)中。
可选地，终端设备可以根据定时器确定所述BWP进入去激活态。例如，所述终端设备可以在所述BWP进入休眠态之后，启动第二定时器。在所述第二定时器超时的情况下，所述终端设备确定所述BWP配置为去激活态。
换句话说，终端设备可以在所述BWP进入休眠态之后，启动第二定时器，并在第二定时器超时的情况下，确定所述BWP为去激活态。采用这种方式可以无需接收网络设备的指示信息，因此可以节约信令开销。
例如，终端设备可以在接收到所述第一指示信息之后，启动第二定时器。或者，终端设备可以在所述第一定时器超时之后，启动第二定时器。
此外，所述终端设备可以在接收所述第一指示信息或者第一定时器超时之后，立即启动所述第二定时器，或者也可以在等待一段时间之后，启动所述第二定时器，本申请对此不作限定。可选地，所述第二定时器的时长可以是网络设备配置的。例如，网络设备可以向所述终端设备发送第三指示信息，所述第三指示信息用于指示所述第二定时器的时长。可选地，每个BWP可以对应一个第二定时器。若存在多个BWP，则可以配置与多个BWP一一对应的第二定时器。
可选地，在一个示例中，终端设备可以接收网络设备发送的第四指示信息，所述第四指示信息用于指示BWP由去激活态切换为休眠态。在接收第四指示信息之后，所述终端 设备将所述BWP配置为休眠态。可选地，所述终端设备在接收所述第四指示信息之后，可以启动第三定时器，在第三定时器超时的情况下，所述终端设备可以将所述BWP从休眠态转移至去激活态。其中，所述第三定时器的时长可以是网络配置的。
例如，图9是本申请又一实施例的通信方法的示意图。图9示出了BWP从休眠态转移到激活态的过程。图9中的第一指示信息承载于辅小区添加消息。如图9所示，该方法包括：
S901、网络设备向终端设备发送辅小区添加消息，相应地，所述终端设备接收所述辅小区添加消息，所述辅小区添加消息中包括所述第一指示信息，所述第一指示信息用于指示所述辅小区中的BWP配置为休眠态。
其中，上述辅小区可以包括一个或多个BWP。上述被配置为休眠态的BWP可以是辅小区中的部分BWP，也可以是辅小区中的全部BWP。上述被配置为休眠态的BWP可以是一个BWP，也可以是多个BWP。
上述第一指示信息例如可以是辅小区中的BWP状态的指示信息。其中上述BWP状态信息可以包括BWP的标识信息，例如，BWP identifier。
可选地，S901中的上述辅小区可以不包括PUCCH辅小区。换句话说，PUCCH所在的辅小区不可被配置为休眠态。

可选地，终端设备在接收到所述第一激活命令之后，可以将所述BWP从休眠态转移到激活态。由于终端设备可以向网络设备上报处于休眠态的BWP的CSI，因而在BWP转移到激活态之后，网络设备可以根据之前接收的CSI，与终端设备快速地进行基于BWP的有效的数据调度。
可选地，上述第一激活命令可以用于激活小区。终端设备可以在接收到第一激活命令之后将BWP从休眠态转移到激活态。或者网络设备还可以向终端设备发送第二激活命令，所述第二激活命令可以用于激活小区中的BWP。终端设备可以在接收第二激活命令之后，激活相应的BWP。
