Description

BWP的调整方法和装置
本申请要求于2019年01月08日提交中国专利局、申请号为201910017002.4、申请名称为“BWP的调整方法和装置”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
本申请涉及通信技术领域，尤其涉及一种带宽部分(Bandwidth Part，BWP)的调整方法和装置。
背景技术
不连续接收(Discontinuous Reception，DRX)是指用户终端(User Equipment，终端设备)周期性的在某些时候进入睡眠状态，在睡眠状态下不监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)子帧，而需要监听PDCCH子帧的时候，从睡眠状态中唤醒，从而，达到终端设备省电的目的。
5G新无线(5G NeW Radio，5G NR)系统的带宽最大能到400MHz，如果要求所有终端设备都支持最大的400MHz，会对终端设备的性能提出很高的要求，不利于降低终端设备的成本，因此，5G NR中引入了自适应带宽(Bandwidth Adaptation，BA)技术，从而，使得终端设备的BWP可以与其服务小区的带宽不一样大，并且可以进行调整。现有技术中，利用BA技术，在一个DRX周期内，终端设备将先在一个窄带BWP上检测是否接收到唤醒信令(Wake Up Signaling，WUS)，若接收到WUS，则终端设备切换到较大带宽的BWP上进行数据收发，在数据收发工作结束后，终端设备切换回到检测WUS的窄带BWP。若没有检测到WUS，则终端设备保持睡眠状态，不被唤醒。
然而，采用现有技术的方式，终端设备存在不必要的开销与功耗。

具体实施方式
图1为本申请的应用系统架构图，本申请的技术方案应用于5G系统，5G系统也称为新无线通信系统、新接入技术(New Radio，NR)或者下一代移动通信系统。终端设备的服务小区的基站gNB/NG-eNB负责为终端设备提供5G NR的用户平面与控制平面协议功能。
5G系统中的接入网可以是无线接入网(radio access network，(R)AN)，5G系统中的(R)AN设备可以由多个5G-(R)AN节点组成，该5G-(R)AN节点可以包括：非3GPP的接入网络如WiFi网络的接入点(access point，AP)、下一代基站(可统称为新一代无线接入网节点(NG-RAN node)，其中，下一代基站包括新空口基站(NR nodeB，gNB)、新一代演进型基站(NG-eNB)、中心单元(central unit，CU)和分布式单元(distributed unit，DU)分离形态的gNB等)、收发点(transmission receive point，TRP)、传输点(transmission point，TP)或其它节点。
如图1所示，5G核心网(5G core/new generation core，5GC/NGC)包括接入和移动性管理功能(Access and Mobility Management Function，AMF)网元、会话管理功能(Session Management Function，SMF)网元、用户面功能(User Plane Function，UPF)网元、鉴权服务器功能(Authentication Server Function，AUSF)网元、策略控制功能(Policy Control Function，PCF)网元、应用功能(Application Function，AF)网元、统一数据管理功能(unified data management，UDM)网元、网络切片选择功能(Network Slice Selection Function，NSSF)网元等多个功能单元。
AMF网元主要负责移动性管理、接入管理等服务。SMF网元主要负责会话管理、终端设备地址管理和分配、动态主机配置协议功能、用户面功能的选择和控制等。UPF主要负责对外连接到数据网络(data network，DN)以及用户面的数据包路由转发、报文过滤、执行服务质量(quality of service，QoS)控制相关功能等。AUSF主要负责对终端设备的认证功能等。PCF网元主要负责为网络行为管理提供统一的策略框架、提供控制面功能的策略规则、获取与策略决策相关的注册信息等。需要说明的是，这些功能单元可以独立工作，也可以组合在一起实现某些控制功能，如对终端设备的接入鉴权、安全加密、位置注册等接入控制和移动性管理功能，以及用户面传输路径的建立、释放和更改等会话管理功能。
5GC中各功能单元之间可以通过下一代网络(next generation，NG)接口进行通信，如：终端设备可以通过NG接口1(简称N1)与AMF网元进行控制面消息的传输，RAN设备可以通过NG接口3(简称N3)与UPF建立用户面数据传输通道，AN/RAN设备可以通过NG接口2(简称N2)与AMF网元建立控制面信令连接，UPF可以通过NG接口4(简称N4)与SMF网元进行信息交互，UPF可以通过NG接口6(简称N6)与数据网络DN交互用户面数据，AMF网元可以通过NG接口11(简称N11)与 SMF网元进行信息交互，SMF网元可以通过NG接口7(简称N7)与PCF网元进行信息交互，AMF网元可以通过NG接口12(简称N12)与AUSF进行信息交互。需要说明的是，图1仅为示例性架构图，除图1中所示功能单元之外，该网络架构还可以包括其他功能单元。
本申请通过网络侧设备向终端设备发送指示信息，以指示终端设备接收和/或发送数据时的工作BWP，从而，可以根据实际接收和/或发送数据的数据量的大小动态调整终端设备的工作BWP，由于终端设备的工作BWP更合理，因此，可以减小不必要的开销与功耗。其中，工作BWP是执行数据传输的BWP。
下面以几个具体的实施例对本申请的技术方案进行描述，其中，相同或者相似的描述可以互相参见，本申请不一一赘述。
图2为本申请提供的一种BWP的调整方法实施例的流程示意图，如图2所示，本实施例的方法如下：
S201:网络侧设备在第一BWP向终端设备发送第一指示信息。
其中，第一指示信息用于指示终端设备接收和/或发送数据的第二BWP的信息，并指示终端设备进入睡眠状态或者唤醒状态。
其中，网络侧设备可以根据接收和/或发送数据的数据量大小确定第二BWP。
第一BWP与第二BWP可以相同也可以不同，对此，本申请不做限制。
第一BWP可以是一个固定的BWP，专门用于收发第一指示信息，通常为一个窄带的BWP，这种情况下，第一BWP与第二BWP不同，第二BWP的带宽大于第二BWP的带宽。
第一BWP也可以是一个即可用于接收和/或发送数据，同时也可以用于收发第一指示信息的BWP，这种情况下，第一BWP与第二BWP可能相同，也可能不同，对此，本申请不做限制。
网络侧设备在第一BWP向终端设备发送第一指示信息包括但不限于如下实现方式：
其中，一种可能的实现方式：
网络侧设备在所述第一BWP向终端设备发送进入睡眠状态(Go To Sleep,GTS)信号，GTS信号中包含所述第二BWP的信息。
其中，GTS是一种在给终端设备配置DRX时可针对终端设备发送的信号。该信号使终端设备在DRX周期内在其服务小区上的激活状态转变为睡眠状态。
另一种可能的实现方式：
网络侧设备在所述第一BWP向终端设备发送WUS，WUS中包含所述第二BWP的信息。
其中，WUS一种在给终端设备配置DRX时可针对终端设备发送的信号。在DRX周期内，终端设备将先检测该信号，若检测到该信号，则终端设备在本DRX周期的持续时间(On Duration)到来时被唤醒，进入激活状态。
S202：终端设备在第二BWP接收和/或发送数据。
终端设备接收到第一指示信息之后，获取第一指示信息所指示的第二BWP。
若第二BWP与所述第一BWP相同，则不进行工作BWP的切换，在终端设备处于激 活状态时在第二BWP接收和/或发送数据。
若第二BWP与所述第一BWP不同，则将工作BWP从第一BWP切换至第二BWP，在终端设备处于激活状态时在第二BWP接收和/或发送数据。
本申请通过网络侧设备向终端设备发送指示信息，以指示终端设备接收和/或发送数据时的工作BWP为第二BWP，以动态调整终端设备的工作BWP，接收和/或发送数据的BWP可以根据实际接收和/或发送数据的数据量确定，因此，终端设备的工作BWP更合理，因此，可以减小不必要的开销与功耗。
图3为本申请提供的另一种BWP的调整方法实施例的流程示意图，图3是在图2所示实施例的基础上，可选地，在S201之前，还可以包括：
S200:网络侧设备向终端设备发送BWP配置信息。
可选地，网络侧设备可以向终端设备发送RRC信令，将所述BWP配置信息携带在所述RRC信令中。
一种可能的实现方式：所述BWP配置信息中包含激活BWP、初始BWP和默认BWP的配置信息。
其中，第二BWP为激活BWP、初始BWP或者默认BWP。
另一种可能的实现方式：BWP配置信息中包含至少两套BWP配置信息，其中，至少两套BWP配置信息可以是基站自定义的。
其中，第二BWP为所述BWP配置信息中包含的至少两套BWP配置信息中一个BWP配置信息所对应的BWP。
可选地，一种可能的实现方式中，每套BWP配置信息都使用相同的公共DRX配置信息，该公共DRX配置信息可以是约定好的，不需要网络侧设备在为终端设备配置BWP配置信息时进行配置。
另一种可能的实现方式，还可以通过在RRC信令中包含所述至少两套BWP配置信息对应的DRX配置信息。其中，DRX配置信息包括但不限于：特定的DRX持续时间定时器、DRX静止定时器参数、DRX上行重传定时器参数或者DRX下行重传定时器参数等，对此本申请不做限。
不同的BWP配置信息对应的DRX配置信息可以相同也可以不同，对此，本申请不做限制。
可选地，网络侧设备还可以通过向终端设备发送BWP重配置信息，以更新上述至少两套BWP配置信息。
S201:网络侧设备在第一BWP向终端设备发送第一指示信息。
S202：终端设备在第二BWP接收和/或发送数据。
S201、S202的详细描述参见图2所示实施例，此处不再赘述。
本申请通过网络侧设备向终端设备发送BWP配置信息，网络侧设备可以根据实际接收和/或发送数据的数据量的大小动态的从BWP配置信息中选择一个第二BWP，向终端设备发送第一指示信息，以指示用于终端设备接收和/或发送数据的第二BWP，由于终端设备的工作BWP更合理，因此，可以减小不必要的开销与功耗。
本申请主要考虑基于GTS信号的DRX机制的场景，以及基于WUS的DRX机制的场景，但并不限于上述两种场景，下面将分别针对两种场景进行描述。
图4至图图6是针对基于GTS信号的DRX机制的场景。
图4为本申请提供的再一种BWP的调整方法实施例的流程示意图，本实施例如下：
S401：网络侧设备在第一BWP向终端设备发送GTS信号。
其中，GTS信号中包含所述第二BWP的信息。
可选地，一种可能的实现方式为：GTS信号为下行控制信息DCI，所述DCI中包含带宽指示字段，所述带宽指示字段用于指示所述第二BWP。终端设备接收到GTS信号后，根据带宽指示字段确定该字段所指示的第二BWP为接收和/或发送数据的工作BWP。
另一种可能的实现方式为：GTS信号为基于序列的信号，基于序列的信号与第二BWP对应。不同的序列码对应不同的BWP配置信息，因此，终端设备接收到GTS信号之后，根据GTS信号的序列码与BWP配置信息的对应关系，可以确定GTS信号的序列码对应的第二BWP为接收和/或发送数据的工作BWP。
S402：终端设备判断第一BWP是否与第二BWP相同。
若相同，执行S403，若不同，执行S404。
S403：终端设备控制终端设备进入睡眠状态，将工作BWP保持在所述第一BWP。
S404：终端设备控制终端设备进入睡眠状态，将工作BWP从所述第一BWP切换至所述第二BWP。
可选地，终端设备控制终端设备进入睡眠状态，并在睡眠状态下将工作BWP从所述第一BWP切换至所述第二BWP。
S405：终端设备在第二BWP接收和/或发送数据。
本实施例，通过网络侧设备在第一BWP向终端设备发送GTS信号，终端设备根据第一BWP是否与第二BWP相同，确定是否在睡眠状态下对工作BWP进行切换，由于终端设备是在睡眠状态下进行工作BWP的切换，从而，可以使得终端设备唤醒之后之后即可在第二BWP进行数据收发，不需要占用终端设备处于激活状态内的时间进行工作BWP的切换，因此，进一步地减少了不必要的功耗和开销。
下面以两个示例对图4所示技术方案进行描述，如图5所示，图5为本申请提供的一个基于GTS信号的DRX机制的场景的示意图。
(1)假设当前为DRX周期1，终端设备处于激活状态，在BWP1上进行数据收发工作。终端设备收到GTS信号，指示终端设备进入睡眠状态，同时指示终端设备下次唤醒后的进行数据收发的工作BWP为BWP2。

(2)终端设备在接收到该GTS信号后，首先进入睡眠状态；在处于睡眠状态时，完成BWP切换，即从激活BWP切换至默认BWP。
(3)当DRX周期2的On Duration到来时，终端设备被唤醒进入激活状态，此时终端设备工作在默认BWP上。
(4)假设在DRX周期2内，终端设备处于激活状态时，收到GTS信号，指示终端设备进入睡眠状态，同时指示终端设备下次唤醒后进行数据收发的工作BWP为初始BWP。
(5)终端设备在接收到该GTS信号之后，首先进入睡眠状态；在处于睡眠状态时，完成BWP切换，即从默认BWP切换至初始BWP。
(6)当DRX周期3的On Duration到来时，终端设备被唤醒进入激活状态，此时终端设备工作在初始BWP上。
(7)假设在DRX周期3内，终端设备处于激活状态时，没有收到GTS信号，或者收到GTS信号指示终端设备下次唤醒后的工作BWP仍然为初始BWP，则终端设备在DRX周期内的激活时间结束之后，直接进入睡眠状态，不需要进行BWP切换。
(8)当DRX周期4的On Duration到来时，终端设备被唤醒进入激活状态，此时终端设备工作在初始BWP上。
图7至图10是针对基于WUS的DRX机制的场景。
图7为本申请提供的又一种BWP的调整方法实施例的流程示意图，本实施例如下：
S701：网络侧设备在第一BWP向终端设备发送WUS。
其中，WUS中包含所述第二BWP的信息。
其中，第一BWP可以是一个固定的BWP，专门用于收发WUS，通常为一个窄带的BWP，第二BWP用于接收和/或发送数据，第二BWP的带宽大于第二BWP的带宽。
可选地，一种可能的实现方式为：
WUS为基于序列的信号，基于序列的信号与第二BWP对应。不同的序列码对应不同的BWP配置信息，因此，终端设备接收到WUS之后，根据WUS的序列码与BWP配置信息的对应关系，可以确定WUS的序列码对应的第二BWP为接收和/或发送数据的工作BWP。
S702：终端设备确定终端设备进入激活状态，将工作BWP从所述第一BWP切换至所述第二BWP。
可选地，终端设备确定终端设备进入激活状态之前，将工作BWP从所述第一BWP切换至所述第二BWP
S703：终端设备在第二BWP接收和/或发送数据。
S704：终端设备确定终端设备激活状态结束，将工作BWP从所述第二BWP切换至所述第一BWP。
可选地，终端设备在激活状态结束后，将工作BWP从所述第二BWP切换至所述第一BWP。
本实施例，通过网络侧设备在第一BWP向终端设备发送WUS，终端设备在进入激活状态前进行工作BWP的切换，终端设备在激活状态结束后，将工作BWP从所述第二BWP切换至所述第一BWP，从而，可以使得终端设备唤醒之后即可在第二BWP进行数据收发，不需要占用终端设备处于激活状态内的时间进行工作BWP的切换，因此，进一步地减少了不必要的功耗和开销。
图8为本申请提供的又一种BWP的调整方法实施例的流程示意图，本实施例如下：
S801：网络侧设备在第一BWP向终端设备发送WUS。
其中，WUS中包含所述第二BWP的信息。
第一BWP可以是一个即可用于接收和/或发送数据，同时也可以用于收发第一指示信息的BWP，这种情况下，第一BWP与第二BWP可能相同，也可能不同，对此，本申请不做限制。
可选地，一种可能的实现方式为：
WUS为基于序列的信号，基于序列的信号与第二BWP对应。不同的序列码对应不同的BWP配置信息，因此，终端设备接收到WUS之后，根据WUS的序列码与BWP配置信息的对应关系，可以确定WUS的序列码对应的第二BWP为接收和/或发送数据的工作BWP。
S802：终端设备判断第一BWP是否与第二BWP相同。
若相同，执行S803，若不同，执行S804。

S807：终端设备将工作BWP保持在所述第二BWP。
S808：将工作BWP从所述第二BWP切换至所述第一BWP。
本实施例，通过网络侧设备在第一BWP向终端设备发送WUS，终端设备根据第一BWP是否与第二BWP相同，确定是否在进入激活状态前对工作BWP进行切换，由于终端设备是在进入激活状态前进行工作BWP的切换，从而，可以使得终端设备唤醒之后之后即可在第二BWP进行数据收发，不需要占用终端设备处于激活状态内的时间进行工作BWP的切换，因此，进一步地减少了不必要的功耗和开销，并且，。若所述终端 设备从所述第一BWP切换至所述第二BWP的次数大于预设阈值，则在所述终端设备在激活状态结束后，所述终端设备将工作BWP保持在所述第二BWP。从而，减少BWP的切换次数，进一步地节省功耗和开销。

一种可能的实现方式：根据持续时间定时器的启动时刻与第一偏移量，确定所述WUS的监听时间。
其中，第一偏移量为所述WUS的发送时刻与所述持续时间定时器的启动时刻之间的偏移量。

当BWP的调整装置为终端设备时，图19示出了一种简化的终端设备的结构示意图。便于理解和图示方便，图19中，终端设备以手机作为例子。如图19所示，终端设备包括处理器、存储器、射频电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对终端设备进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。射频电路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端设备可以不具有输入输出装置。
当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图19中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
在本申请实施例中，可以将具有收发功能的天线和射频电路视为终端设备的收发单元，将具有处理功能的处理器视为终端设备的处理单元。如图19所示，终端设备包括收发单元1110和处理单元1120。收发单元也可以称为收发器、收发机、收发装置等。处理单元也可以称为处理器，处理单板，处理模块、处理装置等。可选的，可以将收发单元1110中用于实现接收功能的器件视为接收单元，将收发单元1110中用于实现发送功能的器件视为发送单元，即收发单元1110包括接收单元和发送单元。收发单元有时也可以称为收发机、收发器、或收发电路等。接收单元有时也可以称为接收机、接收器、或接收电路等。发送单元有时也可以称为发射机、发射器或者发射电路等。
