需要说明的是,图1-图3只是以示例的形式示意本申请所适用的系统,当然,本申请实施例所示的方法还可以适用于其它系统,例如,5G通信系统、LTE通信系统等,本申请实施例对此不作具体限定。
可选地,图1-图3所示的无线通信系统还可以包括移动性管理实体(Mobility Management Entity,MME)、接入与移动性管理功能(Access and Mobility Management Function,AMF)等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
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。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
本申请实施例中,"预先定义"可以通过在设备(例如,包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。比如预先定义可以是指协议中定义的。
本申请实施例中,所述"协议"可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
卫星从其提供的功能上可以分为透传数据(payload)和再生(regenerative)数据两种。对于透传payload卫星,只提供无线频率滤波,频率转换和放大的功能,只提供信号的透明转发,不会改变其转发的波形信号。对于再生payload卫星,除了提供无线频率滤波,频率转换和放大的功能,还可以提供解调/解码,路由/转换,编码/调制的功能,其具有基站的部分或者全部功能。
图4和图5分别示出了基于透传paload卫星和再生payload卫星的NTN场景的示意图。其中,NTN网络可以包括一个或多个网关(Gateway),用于卫星和终端之间的通信。对于基于透传paload卫星的NTN场景,网关和卫星之间通过馈线链路(Feeder link)进行通信,卫星和终端之间可以通过服务链路(service link)进行通信。对于基于再生paload卫星的NTN场景,卫星和卫星之间通过星间(InterStar link)进行通信,网关和卫星之间通过馈线链路(Feeder link)进行通信,卫星和终端之间可以通过服务链路(service link)进行通信。
在上行传输中,为了保证上行传输的正交性,避免小区内(intra-cell)干扰,网络要求来自同一时刻但不同频域资源的不同UE的信号到达网络的时间基本上是对齐的。为了保证网络侧的时间同步,引入了上行定时提前(Time Advance,TA)的机制。
网络侧的上行时钟和下行时钟是相同的,而UE侧的上行时钟和下行时钟之间有偏移,并且不同UE有各自不同的上行定时提前量。网络通过适当地控制每个UE的偏移,可以控制来自不同UE的上行信号到达网络的时间。对于离网络较远的UE,由于有较大的传输时延,就要比离网络较近的UE提前发送上行数据。
图6和图7分别示出了不设置TA和设置TA的情况下的时间传输示意图。从图7可以看出,通过给不同的UE配置对应的TA,能够实现网络侧的时间同步。
在NTN场景中,由于终端和网络之间的信号传输时延较大,为了便于终端完成初始随机接入,网络可以基于近地点与基站之间的信号传输时延确定公共的TA。
对于基于regenerative payload卫星的NTN场景,如图8所示,公共TA=2*D0/c,即可以参考点和卫星之间的信号传输时延确定,对于基于transparent payload的NTN场景,如图9所示,公共TA=2*(D01+D02)/c,即可以根据参考点和网关与卫星之间的信号传输时延确定,其中c表示光速。
由于卫星是高速运动的,这就导致卫星和UE之间的信号传输时延会频繁变化,这种情况下,网络设备如何通知公共TA以用于终端设备的上行传输是一项急需解决的问题。
图10为本申请实施例提供的一种传输公共时间提前量TA的方法200的示意性流程图。如图10 所示,该方法200可以包括如下至少部分内容:
S201,网络设备根据第一更新周期更新包括第一系统信息块(System Information Block,SIB)的系统消息;
S202,终端设备根据所述第一更新周期更新包括第一SIB的系统消息。
在本申请实施例中,所述第一更新周期和第二更新周期不同,所述第二更新周期为包括第二SIB的系统消息的更新周期,所述第一SIB包括第一公共TA,所述第二SIB不包括第一公共TA。即终端设备使用不同的更新周期更新包括第一公共TA的系统消息和不包括第一公共TA的系统消息。
可选地,在本申请实施例中,第一SIB可以是系统消息中的任一SIB,例如SIB1或SIB2等,所述第二SIB也可以是系统消息中的任一SIB,例如,SIB1或SIB2。
在本申请实施例中,为便于区分和说明,将包括第一公共TA的系统消息记为第一系统消息,将不包括第一公共TA的系统消息记为第二系统消息。
应理解,在本申请实施例中,网络设备根据(或者,使用)第一更新周期更新第一系统消息表示网络设备可以以该第一更新周期进行第一系统消息的更新,但并不表示该网络设备在每个第一更新周期均更新该第一系统消息。对应地,终端设备根据(或者,使用)第一更新周期更新第一系统消息表示终端设备可以以该第一更新周期进行第一系统消息的更新,但并不表示该终端设备在每个第一更新周期均进行第一系统消息的更新。
在一个具体实施例中,网络设备可以在某个第一更新周期内发送该第一系统消息的更新指示,进一步在下一个第一更新周期内更新第一系统消息,对应地,若终端设备在某个第一更新周期内接收到第一系统消息的更新指示,则可以在下一个第一更新周期内接收更新的第一系统消息。
应理解,本申请实施例并不限定第一系统消息在第一更新周期内的发送方式。例如该第一系统消息在第一更新周期内可以只发送一次,或者也可以是周期性地重复发送的。
所述第一SIB包括第一公共TA可以为系统消息中的任意一个SIB包括第一公共TA,例如SIB1包括第一公共TA。进一步地,若系统消息中存在一个SIB包括第一公共TA则可以认为该系统消息为第一系统消息。
所述第二SIB不包括第一公共TA可以为系统消息中的任意一个SIB均不包括第一公共TA。进一步地,若系统消息中的任一SIB均不包括第一公共TA,则可以认为该系统消息为第二系统消息。
应理解,在本申请实施例中,第一公共TA可以包含在系统消息的SIB中,或者也可以包含在系统消息中的其他系统信息块中,以下仅以通过SIB承载第一公共TA为例进行说明,但本申请实施例并不限于此。
在本申请一些实施例中,所述第一公共TA为用于非地面网络NTN的公共TA。
可选地,所述第一公共TA对应一个小区,或者,一个波束,或者也可以对应其他服务单元,即可以是一个小区内的终端设备可以共用一个TA,或者一个波束覆盖内的终端可以共用一个TA。
在本申请一些实施例中,所述第一更新周期小于所述第二更新周期。
即用于更新第一公共TA的系统消息的更新频率更高,更新其他系统信息的系统消息的更新频率相对较低,能够适用于需要频繁更新公共TA的NTN网络的需求。
可选地,在另一些实施例中,所述第一更新周期大于所述第二更新周期,此情况可以适用于公共TA不频繁变化的场景。
应理解,本申请实施例中可以适用于公共TA的更新频率和其他系统信息的更新频率不一致的任一场景,以下以公共TA的更新频率高于其他系统消息的更新频率为例进行说明,但本申请并不限于此。
在本申请一些实施例中,所述方法200还包括:
所述终端设备根据第一更新周期系数和参考周期确定所述第一更新周期,其中,所述第一更新周期系数和第二更新周期系数不等,所述第二更新周期系数用于确定所述第二更新周期。
例如,所述终端设备可以将所述第一更新周期系数和所述参考周期的乘积作为所述第一更新周期,将所述第二更新周期系数和所述参考周期的乘积作为所述第二更新周期。
在一些实施例中,所述第一更新周期系数小于所述第二更新周期系数。
在一些实施例中,所述参考周期为默认寻呼周期(defaultPagingCycle)。
可选地,所述第一更新周期系数和所述第二更新周期系数可以通过系统消息配置。
可选地,所述第一更新周期系数和所述第二更新周期系数可以和第一公共TA通过同一个系统消息配置,或者也可以通过不同的系统消息配置。
在本申请一些实施例中,包括第一公共TA的第一系统消息是否更新和不包括第一公共TA的第二系统消息是否更新可以通过不同的消息指示。
作为一个实施例,可以通过不同的短消息(short message)指示第一系统消息是否更新和第二系统消息是否更新。
例如,通过第一短消息指示第一系统消息是否更新,通过第二短消息指示第二系统消息是否更新。
在一些具体实施例中,所述第一短消息中包括系统信息更新(systemInfoModification)字段,该系统信息更新字段用于指示所述第一系统消息是否更新。
在一些具体实施例中,所述第二短消息中包括系统信息更新(systemInfoModification)字段,该系统信息更新字段用于指示所述第二系统消息是否更新。
在一些实施例中,终端设备可以在每个非连续接收(Discontinuous Reception,DRX)周期内的所述终端设备的寻呼时机(Paging Occasion,PO)上监听该第一短消息,此监听方式可以适用于非连接态(例如无线资源控制(Radio Resource Control,RRC)空闲(IDLE)态或者RRC非激活(INACTIVE)态)的终端设备。
在另一些实施例中,终端设备可以在每个第一更新周期内的任意PO上至少监听一次该第一短消息,此方式可以适用于连接态(例如RRCL连接(CONNECTED)态)的终端设备。
在本申请实施例中,PO是一系列物理下行控制信道(Physical Downlink Control Channel,PDCCH)监听时机组成,其中,每个PDCCH监听时机可以包括一个或多个时隙。在一个DRX周期内,终端设备可以在寻呼无线帧(Paging Frame,PF)上的PO上去监听PDCCH。PF可以指一个无线帧,例如为固定10ms,该无线帧可以包含一个或多个PO,或者一个或多个PO的起始位置。
终端设备在一个DRX周期中监听PDCCH的PF和PO可以根据如下方式确定。
例如,PF的系统帧号(System Frame Number,SFN)编号通过以下公式确定:
(SFN+PF_offset)mod T=(T/N)*(UE_ID mod N)
PO位于一个PF内的编号Index(i_s)通过以下公式确定:
i_s=floor(UE_ID/N)mod Ns
其中,T表示终端设备接收寻呼消息的DRX周期。在一些实现中,网络可以广播1个默认的DRX周期,如果网络设备的高层例如,RRC层为UE配置了UE专属的DRX周期,则UE可以将网络广播的DRX周期和高层配置的UE专属的DRX周期中最小的作为该UE的DRX周期。如果网络设备的高层没有为UE配置UE专属的DRX周期,则UE可以将网络广播的DRX周期作为该UE的DRX周期。
N表示一个DRX周期内包含的PF个数;
Ns表示一个PF内包含的PO个数;
PF_offset表示用于确定PF的一个时域偏移量;
UE_ID,例如可以为5G-S-TMSI mod 1024,其中5G-S-TMSI为5G缩短的临时移动用户识别码(Temporary Mobile Subscriber Identity,TMSI)。
应理解,在本申请实施例中,可以通过短消息的发送方式区分所述第一短消息和所述第二短消息。
作为一个示例,所述第一短消息和所述第二短消息对应不同的寻呼无线网络临时标识符(Paging Radio Network Temporary Identity,P-RNTI)。
作为一个示例,所述第一短消息和所述第二短消息对应不同的寻呼搜索空间(paging search space)。
作为一个示例,所述第一短消息和所述第二短消息对应不同的控制资源集(Control Resource Set)。
作为一个示例,所述第一短消息和所述第二短消息对应不同的PDCCH监听时机。
在本申请一些实施例中,若所述终端设备在第一更新周期P内接收到所述第一短消息,并且所述第一短消息指示第一系统消息更新,所述终端设备在下一个第一更新周期(即第一更新周期P+1)内接收(或者说,读取)更新的第一系统消息。
在本申请另一些实施例中,若所述终端设备在第二更新周期Q内接收到所述第二短消息,并且所述第二短消息指示第二系统消息更新,所述终端设备在下一个第二更新周期(即第二更新周期Q+1)内接收(或者说,读取)更新的第二系统消息。
在本申请又一些实施例中,包括第一公共TA的第一统消息是否更新和不包括第一公共TA的第二系统消息是否更新可以通过同一消息指示。例如,通过同一个short message,例如第三短消息指示。
作为一个示例,所述第三短消息包括第一指示域和第二指示域,所述第一指示域用于指示第一系统消息是否更新,第二指示域用于指示第二系统消息是否更新。
可选地,所述第一指示域可以包括至少一个比特,通过该至少一个比特的不同取值指示该第一系统消息是否更新,所述第二指示域可以包括至少一个比特,通过该至少一个比特的不同取值指示该第一系统消息是否更新。
此情况下,终端设备可以在每个DRX周期内的所述终端设备的PO上监听该第三短消息,此方 式可以适用于非连接态的终端设备。或者,终端设备可以在每个第一更新周期内的任意PO上至少监听一次该第三短消息,此方式可以适用于连接态的终端设备。
可选地,若所述终端设备在第一更新周期K内接收到所述第三短消息,并且所述第三短消息中的所述第一指示域指示第一系统消息更新,所述终端设备在下一个第一更新周期(即第一更新周期K+1)内接收更新的第一系统消息。
可选地,若所述终端设备在第二更新周期X内接收到所述第三短消息,并且所述第三短消息中的所述第二指示域指示第二系统消息更新,所述终端设备在下一个第二更新周期(即第二更新周期X+1)内接收更新的第二系统消息。
以下,结合图11和图12,说明具体的执行过程。
在本申请实施例中,终端设备接收网络设备发送的系统消息,该系统消息用于配置以下信息中的至少一个:
系统信息(System Information,SI)调度列表,包括SIB到SI消息的映射关系,SI窗长等;
两个系统消息更新周期系数,即第一更新周期系数和第二更新周期系数,分别记为modificationPeriodCoeff1和modificationPeriodCoeff2;
默认寻呼周期。
其中,modificationPeriodCoef1用于确定所述第一系统消息的更新周期,即包括第一公共TA的系统消息的更新周期,modificationPeriodCoeff2用于确定第二系统消息的更新周期,即不包括第一公共TA的系统消息的更新周期。其中,modificationPeriodCoeff1<modificationPeriodCoeff2。
在一些实施例中,第一更新周期T1=modificationPeriodCoeff1*defaultPagingCycle,即第二更新周期T2=modificationPeriodCoeff2*defaultPagingCycle。
在图11所示的实施例中,通过第一短消息和第二短消息分别指示第一系统消息是否更新和包括第二系统消息是否更新。
终端设备监听第一短消息和第二短消息的行为如下:
处于RRC IDLE态,或者RRC INACTIVE态的终端设备在每个DRX周期在该终端设备的PO上监听第二短消息获取系统消息更新指示。
处于RRC CONNEXTED态的终端设备在每个第二更新周期内的任意PO上至少监听一次第二短消息获取系统消息更新指示。
处于RRC IDLE态,或者RRC INACTIVE态的终端设备在每个DRX周期在该终端设备的PO上监听第一短消息获取系统消息更新指示。
处于RRC CONNEXTED态的终端设备在每个第一更新周期内的任意PO上至少监听一次第一短消息的系统消息更新指示。
可选地,在该实施例中,所述第一短消息和第二短消息可以对应不同的P-RNTI,或者,或对应不同的paging搜索空间,或对应不同的ControlResourceSet,或对应不同的PDCCH监听时机。
如图11所示,如果终端设备在第一更新周期N内接收到第一短消息,指示第一系统消息更新,则终端设备在其对应的下一个第一更新周期(即第一更新周期N+1)读取更新的第一系统消息,获取更新的第一公共TA。或者,如果终端设备在第二更新周期M内接收到第二短消息,指示第二系统消息更新,则终端设备在其对应的下一个第二更新周期(即第二更新周期M+1)读取更新的第二系统消息。
在图12所示的实施例中,通过第三短消息指示第一系统消息是否更新和第二系统消息是否更新。
则终端设备监听第三短消息的行为如下:
处于RRC IDLE态,或者RRC INACTIVE态的终端设备在每个DRX周期在该终端设备的PO上监听第三短消息获取第一系统消息的更新指示和第二系统消息的更新指示。
处于RRC CONNEXTED态的终端设备在每个第一更新周期内的任意PO上至少监听一次第三短消息获取第一系统消息的更新指示和第二系统消息的更新指示。
如果终端设备在第一更新周期N内接收到第三短消息,指示第一系统消息更新,则终端设备在其对应的下一个第一更新周期(即第一更新周期N+1)读取更新的第一系统消息,获取更新的第一公共TA。
如果终端设备在第二更新周期M内接收到第三短消息,指示第二系统消息更新,则终端设备在其对应的下一个第二更新周期(即第二更新周期M+1)读取更新的第二系统消息。
因此,终端设备可以使用不同的更新周期进行包括第一公共TA的系统消息的更新和不包括第一公共TA的系统消息的更新,有利于满足不同场景中对于公共TA的更新频率的要求。
图13为本申请实施例提供的另一种传输公共时间提前量TA的方法300的示意性流程图。如图 13所示,该方法300可以包括如下至少部分内容:

S302,终端设备根据接收的短消息中是否包括第一指示域或第一指示域所指示的内容,确定包括第一系统信息块SIB的系统消息是否更新;
其中,所述短消息包括第二指示域,所述第二指示域用于指示包括第二SIB的系统消息是否更新,所述第一SIB包括第一公共TA,所述第二SIB不包括第一公共TA。
在本申请一些实施例中,所述第一公共TA为用于非地面网络NTN的公共TA。
可选地,所述第一公共TA对应一个小区,或者,一个波束,或者也可以对应其他服务单元,即可以是一个小区内的终端设备可以共用一个TA,或者一个波束覆盖内的终端可以共用一个TA。
可选地,在本申请实施例中,第一SIB可以是系统消息中的任一SIB,例如SIB1或SIB2等,所述第二SIB也可以是系统消息中的任一SIB,例如,SIB1或SIB2。
应理解,在本申请实施例中,第一公共TA可以包含在系统消息的SIB中,或者也可以包含在系统消息中的其他系统信息块中,以下仅以通过SIB承载第一公共TA为例进行说明,但本申请实施例并不限于此。
在本申请实施例中,为便于区分和说明,将包括第一公共TA的系统消息记为第一系统消息,将不包括第一公共TA的系统消息记为第二系统消息。
在本实施例中,网络设备发送的系统消息可以包括第一公共TA或者也可以不包括公共TA,即网络设备可以广播第一系统消息,也可以广播第二系统消息。
在本申请实施例中,网络设备可以通过短消息指示第一系统消息是否更新以及第二系统消息是否更新。
在一些实施例中,可以通过该短消息是否包括第一指示域指示该第一系统消息是否更新,例如,短消息包括第一指示域用于指示第一系统消息更新,短消息不包括第一指示域用于指示第一系统消息未更新。
在另一些实施例中,可以通过该短消息中的第一指示域指示的内容指示该第一系统消息是否更新。例如,若所述第一指示域指示第一系统消息更新,则确定第一系统消息更新,或者,若所述第一指示域指示第一系统消息未更新,则确定第一系统消息未更新。
若终端设备确定第一系统消息更新,所述终端设备则立即读取更新的第一系统消息,获取第一公共TA,而不必等到下一个更新周期再读取更新的第一系统消息,从而能够实现第一公共TA的及时更新。
若确定第二系统消息更新,所述终端设备在下一个更新周期读取更新的第二系统消息。
以下,结合图13,说明具体的执行过程。
在本实施例中,终端设备接收网络设备发送的系统消息,该系统消息用于配置以下信息中的至少一个:
系统信息(System Information,SI)调度列表,包括SIB到SI消息的映射关系,SI窗长等;
一个系统消息更新周期系数,分别记为modificationPeriodCoeff;
默认寻呼周期(defaultPagingCycle)。
其中,modificationPeriodCoef用于确定第二系统消息的更新周期,记为T2。
终端设备监听短消息的行为如下:
处于RRC IDLE态,或者RRC INACTIVE态的终端设备在每个DRX周期在该终端设备的PO上监听短消息获取第一系统消息的更新指示。
处于RRC CONNEXTED态的终端设备在每个默认寻呼周期内的任意PO上至少监听一次短消息获取第一系统消息的更新指示。
若终端设备在t1时刻接收到短消息,该短消息包括第一指示域和第二指示域,该终端设备根据第一指示域确定第一系统消息更新,进一步地,终端设备立即读取更新的第一系统消息,获取更新的第一SIB,从而获取第一公共TA。若终端设备在更新周期M接收到短消息,该短消息包括第二指示域,根据该第二指示域确定第二系统消息更新,进一步地,终端设备在下一个更新周期(即更新周期M+1)读取更新的第二系统消息。
因此,在该实施例中,终端设备在确定包括第一公共TA的第一系统消息更新的情况下,立即读取更新的第一系统消息,而不是等到下一个系统消息更新周期再读取更新的第一系统消息,有利于第一公共TA的及时快速的更新。
