This time delay reduces the efficiency of CA usage and radio resources, especially in small cell deployment scenarios. In a dense small cell deployment scenario, the signaling load of each Scell is also very large, especially when each Scell needs to be configured separately. Therefore, the current CA architecture introduces additional delay, which limits the use of CA and reduces the gain of CA load sharing.

应理解，本文中术语“系统”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。
为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明。
5G中，最大的信道带宽可以是400MHZ(称为宽带载波(wideband carrier))，相比于LTE最大20M带宽来说，宽带载波的带宽很大。如果终端保持工作在宽带载波上，则终端的功率消耗非常大。所以建议终端的射频(Radio Frequency，RF)带宽可以根据终端实际的吞吐量来调整。为此，引入BWP的概念，BWP的动机是优化终端的功率消耗。例如终端的速率很低，可以给终端配置小一点的BWP(如图2-1所示)，如果终端的速率要求很高，则可以给终端配置大一点的BWP(如图2-2所示)。如果终端支持高速率，或者工作在载波聚合(Carrier Aggregation，CA)模式下，可以给终端配置多个BWP(如图2-3所示)。BWP的另一个目的就是触发一个小区中多个参数集(numerology)共存，如图2-3所示，BWP1对应numerology1，BWP2对应numerology2。
通过无线资源控制(Radio Resource Control，RRC)专用信令可以给一个终端配置最多4个上行BWP和最多4个下行BWP，但同一时刻只能有一个上行BWP和下行BWP被激活。在RRC专用信令中，可以指示所配置的BWP中第一个激活的BWP。同时在终端处于连接态过程中，也可以通过下行控制信息(Downlink Control Information，DCI)在不同的BWP之间切换。当处于非激活状态的载波，进入激活状态后，第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。每个BWP的配置参数包括：
-子载波间隔(subcarrierSpacing)；
-循环前缀(cyclicPrefix)；
-BWP的第一个物理资源块(Physical Resource Block，PRB)以及连续的PRB个数(locationAndBandwidth)；
-BWP标识(bwp-Id)；
-BWP公共配置参数和专用配置参数(bwp-Common，bwp-Dedicated)。
终端在进行无线链路监控(Radio Link Monitor，RLM)过程中，只在激活的BWP上执行，非激活的BWP不需要操作，而在不同BWP之间进行切换的时候，也不需要重置RLM相关的定时器和计数器。对于RRM测量，无论终端在哪个激活的BWP上收发数据，都不影响RRM测量。对于CQI的测量，终端也只需要在激活的BWP上执行。
当一个载波被去激活，然后通过媒体接入控制控制单元(Media Access Control Control Element，MAC CE)激活了该载波，则初始的第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。
BWP标识(BWP id)在RRC专用信令中的取值为0到4，BWP标识为0的BWP默认为初始BWP。
在DCI中BWP指示(BWP indicator)为2比特(bit)，如下表1所示。如果配置的BWP个数小于等于3个，则BWP indicator＝1,2,3分别对应BWP id＝1,2,3。如果BWP的个数为4个，则BWP indicator＝0,1,2,3分别对应按照顺序索引配置的BWP。而且网络侧在配置BWP的时候使用连续的BWP id。

表1
为了满足高速率的需求，5G中也支持CA技术。CA通过联合调度和使用多个成员载波(Component Carrier，CC)上的资源，使得NR系统可以支持更大的带宽，从而能够实现更高的系统峰值速率。根据所聚合载波的在频谱上的连续性可以分为，连续性载波聚合和非连续性载波聚合；根据聚合的载波所在的带宽(band)是否相同，分为带内(Intra-band)载波聚合和带间(inter-band)载波聚合。
在CA中，主载波(Primary Cell Component，PCC)有且只有一个，PCC提供RRC信令连接，非接入层(NAS)功能，安全功能等。物理上行控制信道(Physical Uplink Control Channel，PUCCH)在PCC上且只在PCC上存在。辅载波(Secondary Cell Component，SCC)只提供额外的无线资源。PCC和SCC同称为服务小区，其中，PCC上的小区为主小区(Primary cell，Pcell)，SCC上的小区为Scell。标准上还规定聚合的载波最多支持5个，即聚合后的最大带宽为100MHZ，并且聚合载波属于同一个基站。所有的聚合载波使用相同的小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)，基站实现保证C-RNTI在每个载波所在的小区不发生冲突。由于支持不对称载波聚合和对称载波聚合两种，所以要求聚合的载波一定有下行，可以没有上行。而且对于PCC小区来说一定有本小区的PDCCH和PUCCH，而且只有主载波小区有PUCCH，其他辅载波小区可能有PDCCH。
Scell通过RRC专用信令进行配置，初始配置的状态为去激活状态，该状态下不能进行数据收发。然后通过MAC CE进行Scell的激活才能进行数据收发。从Scell配置和激活的时延的角度看，这个架构不是一个最优的架构。而这个时延又降低了CA使用和无线资源的效率，特别是小小区部署场景。在密集小小区部署场景，每个Scell的信令负荷也很大，特别是每个Scell需要单独配置情况下。因此当前CA架构引入了额外的延迟，限制了CA的使用，降低了CA负荷分担的增益。
为此，LTE R15对CA进行了优化，主要优化功能如下：1)Scell的状态分为激活状态和非激活状态，为了实现快速小区恢复，定义了一个新的小区状态，即休眠状态。在休眠状态下，终端测量和上报CQI/RRM，但是不解码PDCCH。同时新定义一个MAC CE控制激活状态和休眠状态之间的转换，如图3-1和图3-2所示，其中，在图3-1中，MAC CE包括1个字节，控制7个小区的状态转换，在图3-2中，MAC CE包括4个字节，控制31个小区的状态状态，其中，C i代表索引号为i的小区对应的状态，C i设置为1代表索引号为i的小区处于休眠状态，C i设置为0代表索引号为i的小区处于激活状态。2)在RRC信令中，可以配置Scell的状态为激活状态或者休眠状态，默认为非激活状态。
目前NR中并没有Scell的休眠状态，为了实现快速恢复Scell，尽快的传输数据，需要引入类似于休眠状态的机制。然而，LTE的休眠状态的机制太过于复杂，需要引入MAC CE进行Scell的状态转换。为此，可以考虑给Scell配置一个叫做休眠BWP(dormant  BWP)的概念。当业务量不大时，可以将有些Scell的BWP通过DCI方式切换到休眠BWP上去。业务量大时，将Scell的休眠BWP通过DCI切换到激活BWP上去来激活小区的业务传输功能，这比传统的休眠Scell的激活时延更短，复杂度更低。休眠BWP与激活BWP之间的切换以及和Scell的状态关系如图4所示。其中，对于休眠BWP与激活BWP之间的切换本申请实施例提出了一种BWP的管理方法，使得资源利用有效，时延更低。
图5为本申请实施例提出的BWP的管理方法的流程示意图，如图5所示，所述BWP的管理方法包括以下步骤：
步骤501：终端接收网络设备发送的第一配置信息，所述第一配置信息包括上行BWP配置信息和下行BWP配置信息。
这里，所述上行BWP配置信息包括至少一个上行BWP配置，所述下行BWP配置信息包括至少一个下行BWP配置；其中，所述上行BWP配置信息携带第一指示信息，所述第一指示信息用于指示上行初始激活BWP对应的BWP标识；所述下行BWP配置信息携带第一指示信息，所述第一指示信息用于指示下行初始激活BWP对应的BWP标识；所述初始激活BWP是指第一个激活的BWP。
本申请实施例中，所述网络设备可以是基站，例如gNB。
本申请实施例中，所述第一配置信息通过RRC专用信令进行配置，其中，所述第一配置信息也称为专用BWP配置信息。专用BWP配置信息包括上行BWP配置信息和下行BWP配置信息。其中，上行BWP配置信息包括N1个上行BWP配置，N1为正整数，进一步，N1为大于等于1且小于等于4的整数。下行BWP配置信息包括N2个下行BWP配置，N2为正整数，进一步，N2为大于等于1且小于等于4的整数。
需要说明的是，上行BWP和下行BWP是独立配置的。本申请实施例中，网络设备独立在上行BWP配置信息和下行BWP配置信息中指示出初始激活BWP，所述初始激活BWP是指第一个激活的BWP。对于上行BWP配置信息来说，网络设备通过在上行BWP配置信息中携带第一指示信息来指示上行初始激活BWP对应的BWP标识。对于下行BWP配置信息来说，网络设备通过在下行BWP配置信息中携带第一指示信息来指示下行初始激活BWP对应的BWP标识。
步骤502：所述终端接收所述网络设备发送的第二指示信息，所述第二指示信息用于指示休眠BWP，所述休眠BWP包括上行休眠BWP和/或下行休眠BWP。
本申请实施例中，休眠BWP具有如下特征：终端在休眠BWP上不用发送上行数据(如PUSCH)，不用接收下行数据(如PDSCH)，不用监听PDCCH，但需要执行CQI测量。
本申请实施例中，所述第二指示信息在所述上行BWP配置信息和所述下行BWP配置信息中独立配置，配置的方式可以但不包括如下两种：
第一种方式：所述上行BWP配置信息携带第二指示信息，所述第二指示信息用于指示上行休眠BWP对应的BWP标识；所述下行BWP配置信息携带第二指示信息，所述第二指示信息用于指示下行休眠BWP对应的BWP标识。
第二种方式：所述上行BWP配置信息中的每个上行BWP配置携带第二指示信息，所述第二指示信息用于指示该上行BWP是否为上行休眠BWP；所述下行BWP的配置信息中的每个下行BWP配置携带第二指示信息，所述第二指示信息用于指示该下行BWP是否为下行休眠BWP。
在一可选实施方式中，所述上行休眠BWP对应的BWP标识和所述下行休眠BWP对应的BWP标识具有关联关系。举个例子：所述上行休眠BWP对应的BWP标识和所述下行休眠BWP对应的BWP标识相同。
本申请实施例中，上行BWP切换和下行BWP切换是独立进行的，然而，对于如下特定的上行BWP切换和下行BWP切换，可以对两者进行关联：上行BWP切换是指上行激活BWP与上行休眠BWP之间的切换，下行BWP切换是指下行激活BWP与下行休眠BWP之间的切换。其中，上行BWP切换和下行BWP切换之间的关联可以通过以下方式实现：所述终端接收所述网络设备发送的第三指示信息，所述第三指示信息用于指示是否同时执行上行BWP切换和下行BWP切换。
基于此，终端执行BWP切换具有如下几种场景：
场景一：所述第三指示信息指示同时执行上行BWP切换和下行BWP切换。
这种场景下，若所述终端确定执行上行BWP切换，则所述终端也执下行BWP切换；或者，若所述终端确定执行下行BWP切换，则所述终端也执上行BWP切换。
场景二：所述第三指示信息指示独立执行上行BWP切换和下行BWP切换。
需要说明的是，所述第三指示信息指示不同时执行上行BWP切换和下行BWP切换也即是所述第三指示信息指示独立执行上行BWP切换和下行BWP切换。
这种场景下，在一实施方式中，若所述终端确定执行上行BWP切换，则在Scell上没有配置PDCCH或者该Scell被配置为跨载波调度在其他载波上的情况下，所述终端也执行下行BWP切换；或者，若所述终端确定执行下行BWP切换，则在Scell上没有配置PUCCH的情况下，所述终端也执上行BWP切换。
这种场景下，在另一实施方式中，若所述终端确定执行上行BWP切换，则所述终端仅执行上行BWP切换；或者，若所述终端确定执行下行BWP切换，则所述终端仅执行下行BWP切换。
上述方案中，所述终端可以通过显示方式或隐式方式来确定是否执行上行BWP切换和下行BWP切换。

显示方式
所述终端接收到所述网络设备发送的第一切换指令后，确定执行上行BWP切换，所述第一切换指令用于指示执行上行BWP切换。所述终端接收到所述网络设备发送的第二切换指令后，确定执行下行BWP切换，所述第二切换指令用于指示执行下行BWP切换。
这里，第一切换指令和第二切换指令可以通过PDCCH(或者说DCI)来实现。
需要说明的是，终端收到上述切换指令后，是否同时执行上行BWP切换和下行BWP切换需要结合前述两种终端执行BWP切换的场景来确定。
举个例子：终端接收到PDCCH，该PDCCH指示执行上行BWP切换，则如果所述第三指示信息指示同时执行上行BWP切换和下行BWP切换，那么终端终端在执行上行BWP切换时，也执行下行BWP切换。或者，终端接收到PDCCH，该PDCCH指示执行下行BWP切换，则如果所述第三指示信息指示同时执行上行BWP切换和下行BWP切换，那么终端在执行下行BWP切换时，也执行上行BWP切换。
举个例子：终端接收到PDCCH，该PDCCH指示执行上行BWP切换，则如果所述第三指示信息指示独立执行上行BWP切换和下行BWP切换，那么终端可以按照以下其中一种方式来实施：1)如果当前Scell没有配置PDCCH或者该Scell配置为跨载波调度在其他载波上，则终端在执行上行BWP切换时，也执行下行BWP切换。2)终端仅执行上行BWP切换。或者，终端接收到PDCCH，该PDCCH指示执行下行BWP切换，则如果所述第三指示信息指示独立执行上行BWP切换和下行BWP切换，那么终端可以按照以下其中一种方式来实施：1)如果当前Scell没有配置PUCCH，即当前Scell不是PUCCH Scell，则终端在执行下行BWP切换时，也执行上行BWP切换。2)终端仅执行下行BWP切换。
本申请实施例的上述方案中，所述执行上行BWP切换是指从当前的上行激活BWP切换到上行休眠BWP上；所述执行下行BWP切换是指从当前的下行激活BWP切换到下行休眠BWP上。或者，所述执行上行BWP切换是指从上行休眠BWP切换到上行初始激活BWP上或者上一次激活的上行BWP上；所述执行下行BWP切换是指从下行休眠BWP切换到下行初始激活BWP上或者上一次激活的下行BWP上。

隐式方式
这里，网络设备配置一个休眠BWP自主切换到激活BWP的门限信息。当门限信息满足条件时，则终端自主切换到初始激活BWP上或者上一次激活的上行BWP上。
具体地，对于上行而言，所述终端确定所述网络设备配置的门限信息满足条件的情况下，确定执行上行BWP切换，所述执行上行BWP切换是指从上行休眠BWP切换到上行初始激活BWP上或者上一次激活的上行BWP上。对于下行而言，所述终端确定所述网络设备配置的门限信息满足条件的情况下，确定执行下行BWP切换，所述执行下行BWP切换是指从下行休眠BWP切换到下行初始激活BWP上或者上一次激活的下行BWP上。
本申请实施例中，上述门限信息为缓存状态报告(Buffer Status Report，BSR)门限信息。
在一实施方式中，网络设备配置一个门限信息，所述终端确定一个逻辑信道组的BSR的值或多个逻辑信道组(如所有的逻辑信道组)的BSR的和的值大于等于所述网络设备配置的门限信息时，触发BSR上报，同时终端自主从休眠BWP切换到初始激活BWP上或者上一次激活的BWP上。
在另一实施方式中，网络设备为每个逻辑信道组配置一个门限信息，此外，还为每个逻辑信道组配置关联的初始激活BWP。可见，每个逻辑信道组关联一个门限信息以及上行初始激活BWP和下行初始激活BWP。所述终端确定一个逻辑信道组的BSR的值大于等于所述网络设备针对该逻辑信道组配置的门限信息时，则触发该逻辑信道组的BSR上报，同时终端自主从休眠BWP切换到该逻辑信道组对应的初始激活BWP上或者上一次激活的BWP上。
除了上述显示方式和隐式方式来实现BWP切换以外，本申请实施例还可以通过定时器来实现BWP切换。具体地，对于上述BWP切换而言，所述终端基于所述网络设备配置的多个定时器，确定执行上行BWP切换。对于下行BWP切换而言，所述终端基于所述网络设备配置的多个定时器，确定执行下行BWP切换。无论是上述BWP切换还是下行BWP切换，都可以通过以下具体过程来实现：
1)所述终端进入初始激活BWP后，启动第一定时器；若所述终端有数据传输，则所述终端重启所述第一定时器；若所述第一定时器超时，则所述终端切换到休眠BWP；或者，所述终端进入初始激活BWP后，若所述终端接收到所述网络设备发送的切换指令，则所述终端切换到休眠BWP。
2)所述终端进入休眠BWP后，启动第二定时器；若所述第二定时器超时，则所述终端切换到初始激活BWP或上一次激活的BWP，并启动第三定时器；若所述第三定时器超时，则所述终端切换到休眠BWP，并启动第二定时器；若所述第三定时器运行期间，所述终端有数据传输，则所述终端重启所述第三定时器。
3)每次启动或重启所述第一定时器或者所述第三定时器时，启动第四定时器；若所述第四定时器超时，则所述终端切换到初始激活BWP或上一次激活的BWP，并启动所述第三定时器和所述第四定时器；若所述第三定时器运行期间，所述终端有数据传输，则所述终端重启所述第三定时器和所述第四定时器。
需要说明的是，对于上行BWP切换而言，上述过程中的初始激活BWP为上行初 始激活BWP，上一次激活的BWP为上一次激活的上行BWP，休眠BWP为上行休眠BWP。对于下行BWP切换而言，上述过程中的初始激活BWP为下行初始激活BWP，上一次激活的BWP为上一次激活的下行BWP，休眠BWP为下行休眠BWP。
举个例子：第一定时器为timer 3，第二定时器为timer 4，第三定时器为timer 1，第四定时器为timer 2。网络设备为终端配置上述定时器，如图6所示，timer 1用于控制终端在激活BWP上停留的时间，timer 2用于控制终端在休眠BWP上停留的时间。timer 2用于控制休眠BWP和激活BWP之间切换的周期。timer3和timer1可以是一个也可以不同的两个定时器。终端在RRC消息中接收到专用BWP配置信息(即所述第一配置信息)之后，默认在网络设备指示的初始激活BWP上准备数据的收发，并执行如下流程：1)启动定时器timer 3，如果终端接收到PDCCH或者接收PDSCH或者发送PUSCH，则重新启动定时器timer 3，如果定时器timer 3超时，则终端自主切换到休眠BWP上。或者，终端接收网络设备发送的DCI，该DCI指示终端切换到休眠BWP。2)终端切换到休眠BWP后，启动定时器timer 4，如果定时器timer 4超时，则终端切换到初始激活BWP上述或者上一次激活的BWP上，并启动定时器timer 1，如果定时器timer 1超时，则终端切换到休眠BWP，并启动定时器timer 4。如果定时器timer 1运行期间，终端接收到PDCCH或者接收PDSCH或者发送PUSCH，则重新启动定时器timer 1。3)每次启动或者重新启动定时器timer 3或者timer 1，终端都启动定时器timer 2，如果定时器timer 2超时，则终端切换到初始激活BWP上或者上一次激活的BWP上，并启动定时器timer 1和timer 2。如果定时器timer 1运行期间，终端接收到PDCCH或者接收PDSCH或者发送PUSCH，则重新启动定时器timer 1和timer 2。
本申请实施例中，上行BWP切换和下行BWP切换是针对一个Scell的(如终端当前的Scell)。不局限于此，上行BWP切换和下行BWP切换还可以针对一组Scell，具体地，所述终端接收所述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执行所述执行上行BWP切换和/或所述下行BWP切换的Scell列表。该Scell列表的每个Scell可以通过服务小区标识(serving cell id)来标识。
本申请实施例中，上述休眠BWP属于静态配置方式，本申请实施例不局限于此，还可以通过动态方式来控制一个BWP是处于休眠状态(休眠BWP)还是处于激活状态(激活BWP)。具体地，所述终端接收所述网络设备发送的第一下行控制信息，所述第一下行控制信息携带第五指示信息，所述第五指示信息用于指示所述终端的第一Scell上的第一BWP处于休眠状态，所述休眠状态是指所述终端在所述第一BWP上没有数据传输且在所述第一BWP上执行CQI测量。
需要说明的是，本申请实施例中的没有数据传输是指不接收PDCCH和PDSCH(针对下行BWP)，不发送PUSCH(针对上行BWP)。本申请实施例中的有数据传输是指接收PDCCH和/或PDSCH(针对下行BWP)，发送PUSCH(针对上行BWP)。
在一实施方式中，所述第五指示信息携带所述第一Scell的标识信息和所述第一BWP的标识信息。
在一实施方式中，默认情况下，所述终端在当前激活的BWP上执行CQI测量，或者所述终端在所述网络设备配置的初始激活BWP上执行CQI测量。
这里，终端的一个Scell上的BWP处于休眠状态下，通过以下任意一种方式来控制该BWP从休眠状态切换到激活状态：
方式一：所述终端接收所述网络设备发送的MAC CE，所述MAC CE携带第六指示信息，所述第六指示信息用于指示将所述第一BWP从休眠状态切换到激活状态。
方式二：所述终端接收所述第一Scell以外的其他处于激活状态的小区发送的第二下行控制信息，所述第二下行控制信息携带第七指示信息，所述第七指示信息用于指示 将所述第一Scell从休眠状态切换到激活状态。进一步，所述第七指示信息携带所述处于激活状态的小区的标识和激活指示信息。
