Abstract

本公开是关于一种BWP切换方法、装置及存储介质。BWP切换方法包括：响应于所述终端配置有初始BWP以及独立小数据包BWP且所述终端被触发从连接态进入到非激活态，确定所述终端切换的目标BWP，所述目标BWP包括初始BWP或者独立小数据包BWP；从激活的BWP切换至所述目标BWP。通过本公开实现连接态进入到非激活态时，BWP的切换配置。

Description

一种BWP切换方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种BWP切换方法、装置及存储介质。
背景技术
新无线(new ratio，NR)标准设计中，引入了接收带宽自适应。通过接收带宽自适应技术，终端可以在一个较小的带宽上监听下行控制信道，以及接收少量的下行数据传输，当终端有大量的数据接收时，则打开整个带宽进行接收。为了更好地支持不能处理整个载波带宽地终端以及接收带宽自适应，NR标准定义了一个新的概念：部分带宽(bandwidth part，BWP)。
BWP技术中，网络设备为空闲态/非激活态(idle/inactive)的终端配置一个初始部分带宽(initial BWP)。终端在无线资源控制连接(RRC_CONNECTED)进入到无线资源控制非激活(RRC_INACTIVE)状态时，将从激活的BWP(active BWP)切换回到initial BWP上终端在initial BWP上接收寻呼(paging)消息，同步信号块(Synchronization Signal and PBCH block，SSB)，系统消息以及发起随机接入等。
NR release 17的讨论中，提出在inactive态支持配置授权的小数据包传输(small data transmission，SDT)。SDT技术中，可以为支持SDT的终端配置一个独立小数据包BWP(separate CG-SDT BWP，或者也称为separate SDT BWP)。当支持SDT的终端配置了separate CG-SDT BWP时，终端可以在separate SDT BWP上进行小数据包的传输，从而可以保证小数据包的传输带宽需求，同时减少initial BWP上的拥塞程度。
当网络设备为终端配置了initial BWP和separate CG-SDT BWP时，终端从连接态进入到非激活态，终端应该切换回到initial BWP和separate CG-SDT BWP中的哪个BWP上，是一个亟待解决的问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例提供的接入方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括终端和网络设备。终端和网络设备之间通过无线资源进行信息的发送与接收。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网络设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分 为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网络设备。该无线接入网络设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，终端状态可以包括连接态(也称为CONNCETED态或RRC_CONNCETED状态)、非激活态(也称为inactive态，或RRC_INACTIVE态)、空闲态(也称为idle状态，或RRC_IDLE态)。NR release 17的讨论中提出在非激活态支持SDT传输，SDT传输可以理解为是不用进入连接态即可完成数据传输，以避免造成时频资源的浪费，缩短数据传输时延，同时节省终端能耗。
SDT传输支持两种方式：分别为基于随机接入过程的SDT和基于半静态的SDT。其中，基于随机接入过程的SDT为：终端通过两步随机接入，或者四步随机接入，在消息A(msgA)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)或者消息3(msg3)中传输上行小数据包。基于半静态的SDT为：网络设备在由连接态转换为非激活态时，在RRC资源释放(RRCrelease)消息中携带SDT传输所需的半静态时频域资源分配信息以及定时提前量(Timing Advance，TA)有效性判断等信息。终端在非激活态有上行数据要传输时，首先进行TA有效性判断、同步信号参考信号接收功率(Synchronization Signal Reference Signal Received Power，SS-RSRP)判断以及数据包大小的判断。当TA有效性、 SS-RSRP以及数据包大小等全部条件满足时，使用网络设备配置的半静态资源进行小数据包的传输。否则，比如当终端待传输的上行数据包的大小超过阈值时，终端则执行四步随机接入过程进入到连接态，在连接态下进行数据传输。
进一步的，4G网络中，默认所有终端都能够处理20MHZ的载波带宽，这种硬性指标会提升4G终端的成本，但能让传输信道占用的频域资源分散到整个带宽中并获得频率分集增益。由于5G NR需要支持非常大的系统带宽(最大到400MHZ)，因此让所有不同的终端接收整个带宽必然是不合理的，例如物联网数据传输一般需要较小的带宽。5G NR标准设计需要考虑下述两个因素：
1)不要求所有终端都具备接收整个载波带宽的能力，NR标准需要为如何处理不同带宽能力的终端引入特别设计。
2)如果要求所有终端都可以接收整个载波带宽，除了需要考虑终端成本，接收整个系统带宽引起的功耗增加也是一个重要的考虑因素。
因此，NR标准设计中，引入了一个新的技术，即接收带宽自适应。通过接收带宽自适应技术，若待发送数据量较少，终端可以在一个较小的带宽上监听下行控制信道，以及接收少量的下行数据传输，当终端有大量的数据接收时，则打开更大的带宽进行接收。为了更好地支持不能处理整个载波带宽地终端以及接收带宽自适应，NR标准定义了BWP。
进一步的，NR协议规定，网络设备可以最多为连接态配置4个BWP，同时可以通过下行控制信息(Downlink Control Information，DCI)、切换定时器(switch timer)以及半静态配置的方式进行BWP的切换。当有数据量较小时，可以将较窄的BWP当作active BWP，并在active BWP上进行数据包的传输。当数据量较大时，可以通过DCI切换到较宽的BWP上，并在较宽的BWP上进行数据传输。
除此之外，相关技术中，网络设备还会为IDLE/非激活态的终端配置一个initial BWP。终端在连接态进入到非激活态时，将从active BWP切换至initial BWP上。图2示出了一种从active BWP切换至initial BWP的示意图。终端在initial BWP上接收paging消息，SSB，系统消息以及发起随机接入等。
进一步的，在Release 17 SDT WI中提出，对于CG-SDT，可以为其配置一个separate SDT BWP。当支持SDT的终端配置了separate SDT BWP时，终端可以在separate SDT BWP上进行小数据包的传输，从而可以保证小数据包的传输带宽需求，并减少initial BWP上的拥塞程度。
然而，当网络设备为终端配置了initial BWP和separate CG-SDT BWP时，终端从连接态进入到非激活态，终端应该切换回至initial BWP和separate CG-SDT BWP中的哪个 BWP上，目前还没有讨论。
有鉴于此，本公开实施例提供一种BWP切换方法，以在终端由连接态进入到非激活态时，确定切换的目标BWP。
本公开实施例提供的BWP切换方法应用于终端配置了initial BWP和separate CG-SDT BWP，并由连接态进入到非激活态的通信场景中。图3示出了一种配置了initial BWP和separate CG-SDT BWP，并由连接态进入到非激活态的通信场景示意图。
本公开实施例中，针对配置了initial BWP和separate CG-SDT BWP的终端，提供一种BWP切换方法，以在终端由连接态进入到非激活态时，确定切换回的BWP为initial BWP或separate CG-SDT BWP。
图4是根据一示例性实施例示出的一种BWP切换方法的流程图，如图4所示，BWP切换方法用于终端中，包括以下步骤。
在步骤S11中，确定终端配置有initial BWP以及separate CG-SDT BWP，且终端被触发从连接态进入到非激活态。
在步骤S12中，确定终端切换的目标BWP，所述目标BWP包括initial BWP或者separate CG-SDT BWP。
在步骤S13中，从激活BWP切换至initial BWP或者separate CG-SDT BWP。
本公开实施例中，终端配置有initial BWP以及separate CG-SDT BWP，响应于终端被触发从连接态进入到非激活态，确定切换至initial BWP或者separate CG-SDT BWP，进而从激活的BWP切换至initial BWP或者separate CG-SDT BWP。
需要说明的是，前述的步骤S11和步骤S12可以同时被执行，或是以任意顺序一前一后被执行，本公开实施例并不对两个步骤的执行时隙进行限定。
一种实施方式中，本公开实施例中，终端确定切换的目标BWP为initial BWP还是separate CG-SDT BWP时，可以采用如下方式中的至少一种：
方式一：基于通信协议，确定终端切换的目标BWP。
一示例中，通信协议规定终端(示例性的，可以包括支持SDT和不支持SDT传输的终端)从连接态进入到非激活态的情况下，始终切换到initial BWP上。即，基于通信协议确定终端切换的目标BWP为initial BWP。
另一示例中，通信协议规定支持SDT的终端，从连接态进入到非激活态的情况下，切换到separate CG-SDT BWP上。即，基于通信协议确定终端切换的目标BWP为separate CG-SDT BWP。
方式二：基于预定义条件，确定终端切换的目标BWP。
其中，预定义条件可以包括切换至separate CG-SDT BWP的条件，和/或包括切换至initial BWP的条件。当然，可以只包括其中之一，且符合条件的终端切换到对应的目标BWP；不符合该条件的终端切换至其他目标BWP。
一示例中，预定义条件包括切换至separate CG-SDT BWP的条件。其中，切换至separate CG-SDT BWP的条件包括以下的至少一种：separate CG-SDT BWP上配置有SSB、paging消息、系统消息、随机接入信道配置。一方面，终端确定满足切换至separate CG-SDT BWP的条件，切换至separate CG-SDT BWP。或者，另一方面，终端确定不满足切换至separate CG-SDT BWP的条件，切换至initial BWP或是其他BWP。
另一示例中，预定义条件包括切换至initial BWP的条件。其中，切换至initial BWP的条件包括以下的至少一种：initial BWP上未配置SSB、paging消息、系统消息以及随机接入信道配置。一方面，终端确定满足切换至initial BWP的条件，切换至initial BWP。或者另一方面，终端确定不满足切换至initial BWP的条件，切换至separate CG-SDT BWP。
又一示例中，预定义条件包括切换至initial BWP的条件和切换至separate CG-SDT BWP的条件。其中，切换至initial BWP的条件和切换至separate CG-SDT BWP的条件可以参考前述表述。一方面，终端确定满足切换至initial BWP的条件，切换至initial BWP；终端确定满足切换至separate CG-SDT BWP的条件，切换至separate CG-SDT BWP；终端确定不满足上述两个条件，切换至其他BWP。
本公开实施例中，基于预定义条件确定终端切换的目标BWP可以理解为是一种隐性方式确定切换的目标BWP的方式。比如，通过隐式方式判断，当终端从连接态进入到非激活态，切换到separate CG-SDT BWP上。比如，当网络设备为separate CG-SDT BWP配置了SSB、paging、系统消息接收、随机接入信道(Random Access Channel，RACH)过程等一种或多种过程所需参数时，支持SDT的终端切换到separate CG-SDT BWP上；否则，切换到initial BWP上。
方式三：基于指示信息，确定终端切换的目标BWP，指示信息用于指示从连接态进入非激活态时切换的目标BWP。
本公开实施例中，网络设备可以通过指示信息指示终端从连接态进入非激活态，切换到哪种BWP上。一方面，指示信息可以指示终端从连接态进入非激活态，切换至initial BWP；则响应于终端从连接态进入非激活态，终端基于指示信息确定切换至initial BWP。另一方面，指示信息可以指示终端从连接态进入非激活态，切换至separate CG-SDT BWP；则响应于终端从连接态进入非激活态，终端基于指示信息确定切换至separate CG-SDT BWP。
一示例中，用于指示终端从连接态进入非激活态时切换的目标BWP的指示信息，可以为已有信令的一个信息元素Information Element，例如可以通过RRC release信令指示，或者也可以通过SDT执行过程中网络设备发送的用于指示BWP切换的指示信息指示。
本公开实施例中，终端在配置有separate CG-SDT BWP和initial BWP的情况下，应用上述方式一、方式二以及方式三中的任意一种实施方式可以确定出从连接态进入非激活态的目标BWP，并从激活的BWP切换至确定的目标BWP上。
本公开实施例提供的BWP切换方法中，终端可以执行SDT传输。其中，SDT传输包括基于半静态的SDT传输，或者包括基于随机接入的SDT传输。
本公开实施例提供的BWP切换方法中，终端执行SDT传输之前或同时，需要进行TA有效性的判断。
一种实施方式中，当前BWP为initial BWP，终端在确定存在待传输的小数据包，并确定SDT传输的时间提前量有效的情况下，从initial BWP切换至separate CG-SDT BWP进行基于半静态的SDT传输。
图5A是根据一示例性实施例示出的一种SDT传输的流程图。该方法既可以单独被实施，也可以结合本公开实施例的其他方法一起被实施；本公开实施例并不对此做出限定。例如，该方法示例性的可以与前述的如图4所示的实施例一起被实施，或是示例性的可以与随后的实施例一起被实施。如图5A所示，SDT传输方法用于终端中，包括以下步骤。
在步骤S21中，确定当前BWP为initial BWP。
在步骤S22a中，确定存在待传输的小数据包，并确定SDT传输的时间提前量有效。
在步骤S23a中，从initial BWP切换至separate CG-SDT BWP进行基于半静态的SDT传输。
本公开实施例另一种实施方式中，当前BWP为initial BWP，终端在确定存在待传输的小数据包，并确定SDT传输的时间提前量无效的情况下，在initial BWP或separate CG-SDT BWP上，进行基于随机接入的SDT传输。
图5B是根据一示例性实施例示出的一种SDT传输的流程图。该方法既可以单独被实施，也可以结合本公开实施例的其他方法一起被实施；本公开实施例并不对此做出限定。例如，该方法示例性的可以与前述的如图4所示的实施例一起被实施，或是示例性的可以与随后的实施例一起被实施。如图5B所示，SDT传输方法用于终端中，包括以下步骤。
在步骤S21中，确定当前BWP为initial BWP。
在步骤S22b中，确定存在待传输的小数据包，并确定SDT传输的时间提前量无效。
在步骤S23b中，在initial BWP或separate CG-SDT BWP上，进行基于随机接入的SDT 传输。
一种实施方式中，当前BWP为separate CG-SDT BWP。一方面，终端在确定存在待传输的小数据包，并确定SDT传输的时间提前量有效的情况下，在separate CG-SDT BWP进行基于半静态的SDT传输。
图6A是根据一示例性实施例示出的一种SDT传输的流程图。该方法既可以单独被实施，也可以结合本公开实施例的其他方法一起被实施；本公开实施例并不对此做出限定。例如，该方法示例性的可以与前述的如图4所示的实施例一起被实施，或是示例性的可以与随后的实施例一起被实施。如图6A所示，SDT传输方法用于终端中，包括以下步骤。
在步骤S31中，确定当前BWP为separate CG-SDT BWP。
在步骤S32a中，确定存在待传输的小数据包，并确定SDT传输的时间提前量有效。
在步骤S33a中，在separate CG-SDT BWP进行基于半静态的SDT传输。
本公开实施例另一种实施方式中终端在确定存在待传输的小数据包，并确定SDT传输的时间提前量无效的情况下，在initial BWP或separate CG-SDT BWP上，进行基于随机接入的SDT传输。
图6B是根据一示例性实施例示出的一种SDT传输的流程图。该方法既可以单独被实施，也可以结合本公开实施例的其他方法一起被实施；本公开实施例并不对此做出限定。例如，该方法示例性的可以与前述的如图4所示的实施例一起被实施，或是示例性的可以与随后的实施例一起被实施。如图6B所示，SDT传输方法用于终端中，包括以下步骤。
在步骤S31中，确定当前BWP为separate CG-SDT BWP。
在步骤S32b中，确定存在待传输的小数据包，并确定SDT传输的时间提前量无效。
在步骤S33b中，在initial BWP或separate CG-SDT BWP上，进行基于随机接入的SDT传输。
本公开实施例提供的BWP切换方法中，终端执行SDT传输的方法实施过程中，终端可以基于从连接态进入非激活态情况下的切换的目标BWP，确定当前BWP，并进行TA有效性的判断，并进行SDT传输。
本公开实施例中，首先，以终端从连接态进入非激活态，切换到的目标BWP为initial BWP为例进行说明。
本公开实施例一种实施方式中，基于通信协议规定，确定终端从连接态进入到非激活态始终切换到initial BWP。或者基于预定义条件，确定终端从连接态进入到非激活态切换到initial BWP。或者基于指示信息确定终端从连接态进入到非激活态切换到initial BWP。
响应于终端从连接态进入到非激活态切换到initial BWP的情况下，且终端有小数据包 待传输；所述终端从initial BWP上切换到separate CG-SDT BWP上进行传输。若当前无SDT传输，则一直驻留在initial BWP上。此外，终端在进行SDT传输之前，通过执行SSB的测量进行TA有效性判断。
本公开实施例中，终端从连接态进入到非激活态切换到initial BWP上的情况下，可进一步基于separate CG-SDT BWP是否配置SSB，采用不同的TA有效性判断方式。
一种实施方式中，终端从连接态进入到非激活态，基于通信协议、预定义条件或者指示信息，确定切换到initial BWP，separate CG-SDT BWP未配置SSB的情况下。终端在initial BWP上执行SSB测量，并将测量得到的参数测量值作为后续进行TA有效性判断的参数参考值，以下将该参数参考值称为第一参数参考值。终端从连接态切换到非激活态后，在执行SDT传输之前，在initial BWP上测量与第一参数参考值相同波束的参数值，以下称为第一参数测量值。基于第一参数参考值以及第一参数测量值，确定SDT传输的时间提前量是否有效。
一示例中，执行SSB测量得到的参数以RSRP为例进行说明。终端在initial BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。其中，终端在initial BWP上执行SSB测量确定作为参考值的RSRP值可以是在进入非激活态之前执行，也可以是在进入非激活态的同时或之后执行。
例如，终端进入非激活态之前，切换到initial BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。终端从连接态切换到非激活态。在非激活态下终端发起SDT之前，在initial BWP上测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。或者，终端从连接态切换到非激活态，在非激活态下，终端切换至initial BWP，在initial BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。在非激活态下终端发起SDT之前，终端再次在initial BWP执行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。
终端将测量值与参考值进行比较，从而判断TA是否有效。在TA有效的基础上，切换到separate CG-SDT BWP上进行SDT传输。否则，在满足SDT传输条件的基础上，在initial BWP上进行RA-based SDT。
另一种方式中，终端从连接态进入到非激活态，基于通信协议、预定义条件或者指示信息，确定切换到initial BWP，separate CG-SDT BWP未配置SSB的情况下，终端在激活的BWP上执行SSB测量，并将测量得到的参数测量值作为后续进行TA有效性判断的参数参考值，以下仍将该参数参考值称为第一参数参考值。其中，网络设备为保证终端在相同波束上执行SSB测量，网络设备为initial BWP配置与第一参数参考值测量使用的波束 相同的波束测量信息。终端从连接态切换到非激活态。在initial BWP上测量与第一参数参考值相同波束的参数值，以下仍称为第一参数测量值。即基于第一参数参考值以及第一参数测量值，确定SDT传输的时间提前量是否有效。
一示例中，执行SSB测量得到的参数以RSRP为例进行说明。终端在进入非激活态之前，首先在激活的BWP上执行SSB测量，并将测量得到的RSRP作为参考值。并且，网络设备将通过高层信令为每个终端在initial BWP上配置单独的与参考值相同的SSB subset波束等测量量。即，网络设备为初始BWP配置与第一参数参考值测量使用的波束相同的波束测量信息。响应于终端进入非激活态且终端要发起SDT，则首先测量initial BWP上网络设备配置的SSB测量来进行TA有效性的验证。例如，测量与RSRP参考值测量时使用的相同的SSB子集。终端将测量值与参考值进行比较，从而判断TA是否有效。在TA有效的基础上，切换到separate CG-SDT BWP上进行SDT传输。否则，在满足SDT传输条件的基础上，在initial BWP上进行RA-based SDT。
本公开实施例中，终端从连接态进入到非激活态，基于通信协议或指示信息确定终端切换的目标BWP为initial BWP；separate CG-SDT BWP配置有SSB的情况下，终端在initial BWP、separate CG-SDT BWP上或激活BWP上执行SSB测量，并将测量得到的参数测量值作为后续进行TA有效性判断的参数参考值，以下将该参数参考值称为第二参数参考值。终端从连接态切换到非激活态，在执行SDT传输之前，在initial BWP或separate CG-SDT BWP上测量与第二参数参考值相同波束的参数值，以下称为第二参数测量值。即基于第二参数参考值以及第二参数测量值，确定SDT传输的时间提前量是否有效。
其中，终端从连接态进入到非激活态，基于通信协议或者指示信息确定终端切换的目标BWP为initial BWP，separate CG-SDT BWP配置有SSB的情况下，可以测量initial BWP上的SSB得到第二参数测量值，也可以测量separate CG-SDT BWP上的SSB得到第二参数测量值。若是测量initial BWP上的SSB得到第二参数测量值，则具体可以参考上述实施例中separate CG-SDT BWP未配置SSB的情况下测量initial BWP上的SSB的执行过程，在此不再赘述。以下对测量separate CG-SDT BWP上的SSB得到第二参数测量值，并基于第二参数参考值以及第二参数测量值，确定SDT传输的时间提前量是否有效的过程进行说明。
一示例中，执行SSB测量得到的参数以RSRP为例进行说明。其中，终端在separate CG-SDT BWP上执行SSB测量确定作为参考值的RSRP值可以是在进入非激活态之前执行，也可以是在进入非激活态的同时或之后执行。
例如，终端进入非激活态之前，切换到separate CG-SDT BWP上执行SSB测量，并保 留测量得到的RSRP值作为参考值。终端从连接态进入到非激活态，从separate CG-SDT BWP切换到initial BWP。在非激活态上进行SDT传输之前，终端首先切换到separate CG-SDT BWP上进行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。或者，终端从连接态切换到非激活态，在非激活态下切换到separate CG-SDT BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。在非激活态下，终端从separate CG-SDT BWP上切换至initial BWP。在终端发起SDT之前，终端再次切换到separate CG-SDT BWP上执行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。
终端将测量值与参考值进行比较，从而判断TA是否有效。在TA有效的基础上进行SDT传输。否则，在满足SDT传输条件的基础上，查看separate CG-SDT BWP上是否有随机接入资源。若separate CG-SDT BWP上存在随机接入资源，则在separate CG-SDT BWP上进行基于随机接入的SDT传输。若在separate CG-SDT BWP上无随机接入资源，则切换回initial BWP上进行基于随机接入的SDT传输。
另一示例中，执行SSB测量得到的参数以RSRP为例进行说明。终端在进入非激活态之前，首先在激活的BWP上执行SSB测量，并将测量得到的RSRP作为参考值。同时，网络设备通过高层信令为separate CG-SDT BWP配置与参考值相同的SSB波束等测量量。即，为独立小数据包BWP配置与第二参数参考值测量使用的波束相同的波束测量信息。终端在进入非激活态并切换到initial BWP上。在确定需要进行SDT传输时，首先从initial BWP切换到separate CG-SDT BWP，同时通过测量网络设备配置的测量量进行TA有效性判断。在TA有效的基础上进行SDT传输。否则，在满足SDT传输条件的基础上，查看separate CG-SDT BWP上是否有随机接入资源。若separate CG-SDT BWP上存在随机接入资源，则在separate CG-SDT BWP上进行基于随机接入的SDT传输。若在separate CG-SDT BWP上无随机接入资源，则切换回initial BWP上进行基于随机接入的SDT传输。
本公开上述实施例提供的BWP切换方法中，基于通信协议或指示信息确定终端切换的目标BWP为initial BWP，并在separate CG-SDT BWP上进行SDT传输，若确定完成SDT传输，则从separate CG-SDT BWP切换至initial BWP。例如，若SDT传输执行完成后，终端仍处于非激活态，则将从separate CG-SDT BWP上切换到initial BWP上。比如，终端接收到RRC release信令后，将从separate CG-SDT BWP上切换到initial BWP上。
本公开实施例以下以一种情况为例进行说明，即：终端从连接态进入非激活态且切换的目标BWP为separate CG-SDT BWP，确定当前BWP，进行TA有效性的判断，并进行SDT传输。需要说明的是，以下的情况只是一种可能的实施方式，其他情况的实施方式可 以与以下的实施方式类似。
本公开实施例中，终端从连接态进入非激活态且切换的目标BWP为separate CG-SDT BWP的情况下，终端需为支持SDT传输的终端，并且协议规定或基站为支持SDT的终端配置了separate CG-SDT BWP。
本公开实施例一种实施方式中，基于通信协议规定确定，终端从连接态进入到非激活态始终切换到separate CG-SDT BWP。或者基于预定义条件确定，终端从连接态进入到非激活态切换到separate CG-SDT BWP。或者基于指示信息确定，终端从连接态进入到非激活态，切换到separate CG-SDT BWP。
响应于终端从连接态进入到非激活态并切换到separate CG-SDT BWP，当终端有SDT传输时，确定TA是否有效。在TA有效的情况下，在separate CG-SDT BWP上进行基于半静态的SDT传输。在TA无效的情况下，在separate CG-SDT BWP或initial BWP上进行基于随机接入的SDT传输。
本公开实施例中，终端从连接态进入到非激活态且切换到separate CG-SDT BWP的情况下，可进一步基于separate CG-SDT BWP是否配置SSB，采用不同的TA有效性判断方式。
一种实施方式中，为了避免进行BWP的频繁切换，协议规定必须在separate SDT BWP上配置SSB、paging消息、系统消息、PRACH信道配置等一种或多种参数。或者separate CG-SDT BWP必须将initial BWP包含在自身带宽范围内，即，separate CG-SDT BWP中包括initial BWP。
一种实施方式中，响应于终端从连接态进入到非激活态，基于通信协议、预定义条件或指示信息或通过其他任何，确定切换到separate CG-SDT BWP，separate CG-SDT BWP中包括initial BWP或者separate SDT BWP上配置SSB、paging消息、系统消息、PRACH信道配置等一种或多种参数。终端在separate CG-SDT BWP上或激活BWP上执行SSB测量，并将测量得到的参数测量值作为后续进行TA有效性判断的参数参考值，以下将该参数参考值称为第三参数参考值。响应于终端进入非激活态，在执行SDT传输之前，在separate CG-SDT BWP上测量与第三参数参考值相同波束的参数值，以下称为第三参数测量值。基于第三参数参考值以及第三参数测量值，确定SDT传输的时间提前量是否有效。
一示例中，执行SSB测量得到的参数以RSRP为例进行说明。其中，终端在separate CG-SDT BWP上执行SSB测量确定作为参考值的RSRP值可以是在进入非激活态之前执行，也可以是在进入非激活态的同时或之后执行。
例如，终端进入非激活态之前，切换到separate CG-SDT BWP上执行SSB测量，并保 留测量得到的RSRP值作为参考值。终端从连接态进入非激活态，切换至separate CG-SDT BWP。在发起SDT传输之前，在separate CG-SDT BWP上进行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。或者，终端从连接态切换到非激活态，切换至separate CG-SDT BWP，在separate CG-SDT BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。在终端发起SDT之前，终端再次在separate CG-SDT BWP上执行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。
终端将测量值与参考值进行比较，从而判断TA是否有效。在TA有效的基础上进行SDT传输。否则，在满足SDT传输条件的基础上，查看separate CG-SDT BWP上是否有随机接入资源。若separate CG-SDT BWP上存在随机接入资源，则在separate CG-SDT BWP上进行基于随机接入的SDT传输。若在separate CG-SDT BWP上无随机接入资源，则切换回initial BWP上进行基于随机接入的SDT传输。
另一示例中，执行SSB测量得到的参数以RSRP为例进行说明。终端在进入非激活态之前，首先在激活的BWP上执行SSB测量，并将测量得到的RSRP作为参考值。同时，网络设备通过高层信令为separate CG-SDT BWP配置与参考值相同的SSB波束等测量量。即，为独立小数据包BWP配置与第三参数参考值测量使用的波束相同的波束测量信息。终端进入非激活态后，将切换到separate CG-SDT BWP上。若确定需要进行SDT传输，首先需要测量相应的SSB从而进行TA有效性验证。在TA有效地基础上，进行SDT传输。否则，在满足SDT传输条件的基础上，查看separate CG-SDT BWP上是否有随机接入资源。若separate CG-SDT BWP上存在随机接入资源，则在separate CG-SDT BWP上进行基于随机接入的SDT传输。若在separate CG-SDT BWP上无随机接入资源，则切换回initial BWP上进行基于随机接入的SDT传输。
一种实施方式中，执行SSB测量得到的参数以RSRP为例进行说明。本公开实施例中可以基于通信协议规定separate CG-SDT BWP上必须配置随机接入资源，实现在separate CG-SDT BWP上进行基于随机接入的SDT传输。
其中，终端连接态进入到非激活态，基于通信协议或指示信息或通过其他任何方式确定终端切换的目标BWP为separate CG-SDT BWP，且separate CG-SDT BWP中未配置SSB。终端在initial BWP上或激活BWP上执行SSB测量，并将测量得到的参数测量值作为后续进行TA有效性判断的参数参考值，以下将该参数参考值称为第四参数参考值。在执行SDT传输之前，在initial BWP上测量与第四参数参考值相同波束的参数值，以下称为第四参数测量值。基于第四参数参考值以及第四参数测量值，确定SDT传输的时间提前量是否有效。 在一些实施方式中，可以在进入非激活态后且在执行SDT传输之前，实行上述步骤以确定第四参数测量值。
一示例中，执行SSB测量得到的参数以RSRP为例进行说明。其中，终端在initial BWP上执行SSB测量确定作为参考值的RSRP值可以是在进入非激活态之前执行，也可以是在进入非激活态的同时或之后执行。
例如，终端进入非激活态之前，切换到initial BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。终端从连接态进入非激活态，从initial BWP切换至separate CG-SDT BWP。若终端需要执行SDT传输，首先从separate CG-SDT BWP切换到initial BWP上测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。或者，终端从连接态切换到非激活态，在非激活态下，切换到initial BWP上执行SSB测量，并保留测量得到的RSRP值作为参考值。终端从initial BWP切换至separate CG-SDT BWP。终端发起SDT之前，终端再次从separate CG-SDT BWP切换到initial BWP上，在initial BWP执行SSB测量，测量与RSRP参考值测量时使用的相同的SSB子集的RSRP值，作为测量值。
终端将测量值与参考值进行比较，从而进行TA有效性判断。若TA有效，则切换到separate CG-SDT BWP上进行SDT传输。若TA无效，则在满足基于随机接入的SDT传输的条件下，终端可以在initial BWP上进行基于随机接入的SDT传输。此外，若separate CG-SDT BWP上配置了随机接入资源，终端也可以切换到separate CG-SDT BWP上进行基于随机接入的SDT传输。
另一示例中，执行SSB测量得到的参数以RSRP为例进行说明。终端在进入非激活态之前，首先在激活的BWP上执行SSB测量，并将测量得到的RSRP作为参考值。同时，网络设备通过高层信令为initial BWP配置与参考值相同的SSB波束等测量量。即，网络设备为独立小数据包BWP配置与第四参数参考值测量使用的波束相同的波束测量信息。终端进入非激活态后，切换至separate CG-SDT BWP上。终端在需要执行SDT传输时，首先切换到initial BWP上进行TA有效性判断。若TA有效，则切换到separate CG-SDT BWP上进行SDT传输。若TA无效，则在满足基于随机接入的SDT传输的条件下，终端可以在initial BWP上进行基于随机接入的SDT传输。此外，若separate CG-SDT BWP上配置了随机接入资源，终端也可以切换到separate CG-SDT BWP上进行基于随机接入的SDT传输。
可以理解的是，本公开上述实施例中涉及的终端从initial BWP上切换到separate CG-SDT BWP上，或者从separate CG-SDT BWP上切换到initial BWP上，可以是终端自 主切换，也可以是首先由终端进行切换请求上报，然后由网络设备指示进行切换。
本公开实施例提供的应用于终端的BWP切换方法，可以理解为是当为支持SDT的终端配置了separate CG-SDT BWP时，终端从连接态进入到非激活态时的BWP切换方法，能够确定出切换的目标BWP是separate CG-SDT BWP，还是initial BWP，从而有效支持separate CG-SDT BWP的配置，以减小initial BWP上的拥塞程度。
