如图1所示,本公开实施例提供的一种上行切换的方法可应用于无线通信系统100,该无线通信系统可以包括但不限于网络设备101和用户设备102。用户设备102被配置为支持载波聚合,用户设备102可连接至网络设备101的多个载波单元,包括一个主载波单元以及一个或多个辅载波单元。
应理解,以上无线通信系统100既可适用于低频场景,也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution,LTE)系统、LTE频 分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access,WiMAX)通信系统、云无线接入网络(cloud radio access network,CRAN)系统、未来的第五代(5th-Generation,5G)系统、新无线(new radio,NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network,PLMN)系统等。
以上所示用户设备102可以是用户设备(user equipment,UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station,MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备102可具备无线收发功能,其能够与一个或多个通信系统的一个或多个网络设备101进行通信(如无线通信),并接受网络设备101提供的网络服务,这里的网络设备101包括但不限于图示基站。
其中,用户设备102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)设备、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网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备101可以是接入网设备(或称接入网站点)。其中,接入网设备是指有提供网络接入功能的设备,如无线接入网(radio access network,RAN)基站等等。网络设备具体可包括基站(base station,BS)设备,或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备可以是可穿戴设备或车载设备。网络设备也可以是具有通信模块的通信芯片。
比如,网络设备101包括但不限于:5G中的下一代基站(gnodeB,gNB)、LTE系统中的演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、WCDMA系统中的节点B(node B,NB)、CRAN系统下的无线控制器、基站控制器(basestation controller,BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(baseband unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)或移动交换中心等。
对于两个上行载波处于共站址基站的场景中,基于UE到共站址基站仅有一个距离值,两个上行载波的定时提前值(Timing Advance,TA)属于同一个定时提前组(Timing Advance Group,TAG),因此两个上行载波的TA是相同的。
而对于两个上行载波处于不同地理位置基站的场景中,UE到不同地理位置基站的距离以及传输途径损耗均不同,两个上行载波的TA不同、位于不同的TAG。因此对UE而言,两个上行载波相对于下行载波的时间提前量不一致,两个上行载波在时间上无法对齐。在此种场景中,UE在上行切换时涉及在不同的TAG中切换,需合理配置切换时间,以克服两个上行载波的TA重叠时的影响。
本公开实施例提供了一种上行切换的方法,图2是根据一示例性实施例示出的一种上行切换的方法的流程图,如图2所示,该方法包括步骤S201~S206,具体的:
步骤S201,用户设备102向网络设备101发送切换能力信息,切换能力信息用于指示用户设备102从第一上行载波切换至第二上行载波所需的切换时长。
步骤S202,网络设备101接收用户设备102发送的切换能力信息,切换能力信息用于指示用户设备102从第一上行载波切换至第二上行载波所需的切换时长。
步骤S203,网络设备101根据切换时长、第一上行载波的第一定时提前值和第二上行载波的第二定时提前值,确定切换时间配置信息。
步骤S204,网络设备101向用户设备102发送切换时间配置信息。
步骤S205,用户设备102接收网络设备101发送的切换时间配置信息。
步骤S206,用户设备102根据切换时间配置信息,从第一上行载波切换至第二上行载波。
在一些可能的实施方式中,在用户设备102所发送的切换能力信息中,可在设定的两个或多个比特位携带切换时长。
在一些可能的实施方式中,第一上行载波CC1和第二上行载波CC2对应于不同地理位置的基站。两个上行载波的定时提前值属于不同的TAG。
本公开实施例中,用户设备102根据自身切换能力向网络设备101上报自身的切换能力信息,以将从第一上行载波切换至第二上行载波所需的切换时长告知网络设备101。网络 设备101在获知切换时长后,能够根据切换时长以及两个上行载波的定时提前值,为用户设备102配置更合理的上行切换的切换时间配置信息。用户设备102根据网络设备101配置的切换时间配置信息执行上行切换,更高效的完成上行切换,节省网络开销。
本公开实施例提供了一种上行切换的方法,应用于网络设备101,图3是根据一示例性实施例示出的一种上行切换的方法的流程图,如图3所示,该方法包括步骤S301~S303:
步骤S301,接收用户设备102发送的切换能力信息,切换能力信息用于指示用户设备102从第一上行载波切换至第二上行载波所需的切换时长。
步骤S302,根据切换时长、第一上行载波的第一定时提前值和第二上行载波的第二定时提前值,确定切换时间配置信息。
步骤S303,向用户设备102发送切换时间配置信息。
在一些可能的实施方式中,切换能力信息中所指示的从第一上行载波CC1切换至第二上行载波CC2的切换时长为Ts。
在一些可能的实施方式中,CC1的第一定时提前值为NTA1,CC2的第二定时提前值为NTA2,NTA1与NTA2之间存在差异,二者属于不同的TAG。网络设备101根据Ts、NTA1与NTA2三者之间的关系,能够确定合理的切换时间配置信息。
在一些可能的实施方式中,切换时间配置信息用于指示用户设备102的切换起始时间。
在一示例中,若NTA1>NTA2,结合图7和图8所示,网络设备101可利用CC1的第一时隙结束位置和CC2的第二时隙开始位置之间的时域区间,配置切换起始时间。并保证上行切换前后的上行传输不受影响。
在一示例中,若NTA1<NTA2,结合图9所示,网络设备101可利用CC1的第一时隙结束位置之前的部分时域区间,配置切换起始时间。并保证上行切换前后的上行传输不受影响。
本公开的方法中,网络设备101根据用户设备102所上报的切换能力信息,获知用户设备102从第一上行载波切换至第二上行载波所需的切换时长。在此基础上,网络设备101能够根据切换时长以及两个上行载波的定时提前值,为用户设备102配置更合理的上行切换的切换时间配置信息,如切换起始时间。。有利于用户设备102根据网络设备101所配置的切换时间配置信息,更好的完成上行切换。
本公开实施例提供了一种上行切换的方法,应用于网络设备101,图4是根据一示例性实施例示出的一种上行切换的方法的流程图,如图4所示,该方法包括步骤S401~S403:
步骤S401,接收用户设备102发送的切换能力信息,切换能力信息用于指示用户设备102从第一上行载波切换至第二上行载波所需的切换时长。
步骤S402,响应于第一定时提前值大于第二定时提前值,并且,第一差值大于切换时长,确定切换起始时间位于第一区间内;
其中,第一差值为第一定时提前值与第二定时提前值的差,第一区间的起始位置为第一上行载波对应的第一时隙的结束位置,第一区间的结束位置为第一区间的起始位置之后第一时长,第一时长为第一差值与切换时长的差。
步骤S403,向用户设备102发送切换时间配置信息。
在一些可能的实施方式中,在NTA1>NTA2时,记第一差值Td=NTA1-NTA2。结合第一差值Td与切换时长Ts的大小关系,网络设备101所配置的切换起始时间不同。如图7所示,在NTA1>NTA2,且Td>Ts时,Td对应于:第一时隙slot(n-1)的结束位置与第二时隙slot n的起始位置之间的时域区间,Ts位于Td内。网络设备101可在Td对应的时域区间内配置切换起始时间。
在一些可能的实施方式中,第一区间所限定的时域区间包含于Td内,第一区间的起始位置t1与结束位置t2可参照图7所示意的位置,其中,t1即第一时隙slot(n-1)的结束位置。切换起始时间配置在第一区间[t1,t2]中。
在一示例中,t2是切换起始位置所能配置的最晚时域位置,t2与第二时隙的起始位置之间的时域区间应不小于切换时长Ts,即第一区间对应的第一时长应满足:第一时长=Td-Ts。
在一示例中,切换起始时间配置在t1位置,切换时长为Ts,用户设备102能够在Td内完成第一上行载波CC1到第二上行载波CC2的切换。本示例中,网络设备101可下发正常的上行调度配置信息,以便于用户设备102在CC1的第一时隙中发送对应的上行数据,在CC2的第二时隙中发送对应的上行数据。
在一示例中,切换起始位置配置在t2位置,切换时长为Ts,用户设备102仍能够在Td内完成第一上行载波CC1到第二上行载波CC2的切换。相应的,网络设备101仍可下发正常的上行调度配置信息。
本公开实施例的方法中,在NTA1>NTA2,且Td>Ts的场景中,网络设备101可在第一 区间内配置切换起始时间,以便于切换时长可完整配置于两个上行载波的第一差值Td内。从而用户设备102根据切换配置信息所指示的切换起始时间,能够在Td内完成上行切换,并且在上行切换前后均不会影响第一时隙和第二时隙的正常上行数据传输。
本公开实施例提供了一种上行切换的方法,应用于网络设备101,图5是根据一示例性实施例示出的一种上行切换的方法的流程图,如图5所示,该方法包括步骤S501~S503:
步骤S501,接收用户设备102发送的切换能力信息,切换能力信息用于指示用户设备102从第一上行载波切换至第二上行载波所需的切换时长。
步骤S502,响应于第一定时提前值大于第二定时提前值,并且,第一差值小于切换时长,确定切换起始时间为第一时间位置;
其中,第一差值为第一定时提前值与第二定时提前值的差,第一时间位置位于第一上行载波对应的第一时隙的结束位置之前的第二时长,第二时长为切换时长与第一差值的差。
步骤S503,向用户设备102发送切换时间配置信息。
在一些可能的实施方式中,结合图8所示,在NTA1>NTA2,且Td<Ts时,Td仍对应于:第一时隙slot(n-1)的结束位置与第二时隙slot n的起始位置之间的时域区间,此时Ts包括Td和第一时隙slot(n-1)的一部分。网络设备101在Td对应的时域区间内配置切换起始时间。
在一些可能的实施方式中,第一时间位置t3与第一时隙的结束位置t1可参照图8所示意的位置,切换起始时间配置在t3,且切换时长Ts满足:Ts=第二时长+Td,第二时长为Ts-Td。
本公开实施例中,在NTA1>NTA2,且Td<Ts的场景中,网络设备101仍可利用Td配置切换时间。本公开的场景中,将第一时间位置配置为切换起始时间,有利于保证切换时长能够最大限度的占用Td,并在第一时隙中预留出额外的切换时间。以便于用户设备102在上行切换时,既可以有效实现上行切换,又可以减少对第一时隙内上行数据传输的影响。

其中,第一差值为第一定时提前值与第二定时提前值的差,第一时间位置位于第一上行载波对应的第一时隙的结束位置之前的第二时长,第二时长为切换时长与第一差值的差。
步骤S503,向用户设备102发送切换时间配置信息。
步骤S504,向用户设备102发送上行调度配置信息,上行调度配置信息用于指示禁止用户设备102在切换起始时间与第一时隙的结束位置之间的时域区间发送上行数据。
在一些可能的实施方式中,结合图8所示,对于切换起始时间t3与第一时隙的结束位置t1之间的时域区间,即切换时长Ts所占用的第一时隙中的第一时长部分,网络设备101可通过下发的上行调度配置信息,指示用户设备102在此第一时长内不进行上行数据发送。
本公开实施例中,网络设备101通过下发上行调度配置信息,有效指示用户设备102在上行数据发送过程中,避开切换时长所占用第一时隙的部分。有利于在有效的时间内进行上行数据发送,避免上行数据丢失。

步骤S502,响应于第一定时提前值大于第二定时提前值,并且,第一差值小于切换时长,确定切换起始时间为第一时间位置;
其中,第一差值为第一定时提前值与第二定时提前值的差,第一时间位置位于第一上行载波对应的第一时隙的结束位置之前的第二时长,第二时长为切换时长与第一差值的差。
步骤S503,向用户设备102发送切换时间配置信息。
步骤S505,确定切换起始时间与第一时隙的结束位置之间对应的符号的第一数量;
步骤S506,向用户设备102发送上行调度配置信息,上行调度配置信息用于指示第一数量。
在一些可能的实施方式中,仍可结合图8所示,对于切换时长Ts所占用的第一时隙中的时域区间,网络设备101还可计算确定此时域区间内的符号(symbol)数量即第一数量。网络设备101在上行调度配置信息中指示此第一数量,以便于用户设备102根据第一 数量确定Ts所占用的符号,从而在此第一数量的符号中不进行上行数据发送。
本公开实施例中,网络设备101通过下发上行调度配置信息,指示所配置的切换时长在第一时隙中占用的符号数量。以便于用户设备102在所指示数量的符号中不进行上行数据发送,以免上行数据丢失。

步骤S603,向用户设备102发送切换时间配置信息。
在一些可能的实施方式中,结合图9所示,当NTA1<NTA2,第一差值Td可对应于第一时隙与第二时隙重叠的时域区间。网络设备101可在第一时隙内配置切换起始时间。
如图9所示,网络设备101在配置切换时间过程中,可以第一时隙的结束位置t1作为切换时间的结束位置。第二时间位置t4与t1间的第三时长满足:第三时长=切换时长Ts+Td。

在一些可能的实施方式中,切换时间配置信息用于指示用户设备的切换起始时间。
在一些可能的实施方式中,用户设备102根据网络设备101所配置的切换起始时间,从此切换起始时间开始进行上行切换,所需的切换时长为Ts。
本公开实施例中,用户设备102根据自身切换能力向网络设备101上报自身的切换能力信息,以告知网络设备101所需的上行切换的切换时长。网络设备101在获知切换时长后,能够根据切换时长以及两个上行载波的定时提前值,为用户设备102配置更合理的上行切换的切换时间配置信息,如切换起始时间。用户设备102根据网络设备101配置的切换时间配置信息执行上行切换,更高效的完成上行切换。

其中,第一差值为第一定时提前值与第二定时提前值的差,第一区间的起始位置为第一上行载波对应的第一时隙的结束位置,第一区间的结束位置为第一区间的起始位置之后第一时长,第一时长为第一差值与切换时长的差。
本公开实施例中,结合图7所示,在NTA1>NTA2且Td>Ts的场景中,用户设备102根据网络设备101的配置,能够在第一差值Td内完成上行切换,在上行切换前后均不会影响第一时隙和第二时隙的正常上行数据传输。

其中,第一差值为第一定时提前值与第二定时提前值的差,第一时间位置位于第一上行载波对应的第一时隙的结束位置之前的第二时长,第二时长为切换时长与第一差值的差。

本公开实施例提供了一种上行切换的方法,应用于用户设备102,该方法包括步骤S1001~S1003,该方法中:
若第一上行载波的第一定时提前值小于第二上行载波的第二定时提前值,切换时间配置信息指示切换起始时间为第二时间位置;
其中,第二时间位置位于第一上行载波对应的第一时隙的结束位置之前的第三时长,第三时长为切换时长与第一差值的和,第一差值为第一定时提前值与第二定时提前值的差。
本公开实施例中,结合图9所示,在NTA1<NTA2场景中,用户设备102根据网络设备101的配置,在第一时隙结束前即开始上行切换,在第一时隙结束时结束上行切换。
