Description

载波跳转的方法、终端和基站 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及一种载波跳转的方法、终端和基站。
背景技术
当前,无线蜂窝系统正逐步开始考虑通过使用免授权(Unlicensed)频段,如使用2.4GHz频段、5.8GHz频段扩展使用频率。其主要手段包括授权辅助接入(License Assisted Access,LAA)技术与长期演进(Long Term Evolution,LTE)/无线保真(Wireless-Fidelity,Wi-Fi)聚合技术两种。这两种聚合技术的主要特点包括:(1)被聚合资源包括免授权频段,免授权频段仅作为授权频段的辅助频段使用;(2)免授权频段的使用不仅受限于基站调度,也受限于该频段的负载,即需要经过竞争机制才能够使用。
在现有阶段,免授权频段仅是作为授权频段的补充。例如,LAA技术中,免授权频段尽管可以采用LTE的工作方式,但是只能作为授权频段的辅载波。未来,使用免授权频段可能会在现有基于载波聚合的LAA技术基础上,支持独立工作模式,即终端可以独立驻留、接入免授权频段的载波,并通过该载波发送或者接收数据。为了支持免授权频段的载波独立工作功能,最为简单的方法为将现有的LTE系统中应用于授权频段的广播机制、寻呼机制以及上下行接入与传输机制全部引入免授权频段。但是,由于免授权频段为公共频段,不仅LTE系统可以在上面工作,其他系统如Wi-Fi,也可以在上面工作。
因此,在现有使用免授权频段的LAA系统中为了满足多系统共享频率资源的管制需求,引入了先听后讲(Listen Before Talk,LBT)机制,即在终端使用免授权频段之前,需要针对信道的质量以及干扰情况进行测量,并且监听信道是否有人占用后,方可进行使用。
现有的LAA系统除了引入LBT机制以外,大体上沿用LTE现有机制与流程,即确定免授权频段的固定载波与固定带宽,作为系统工作频率与带宽。终端通过将授权频段作为主载波进行系统信息以及无线资源控制(Radio Resource Control,RRC)信息的发送与接收载体进行接入,并进行数据传输。 系统通过主载波承载的RRC信令将LAA载波作为辅载波配置给终端。在整个过程中,系统带宽以及系统工作的中心频率保持不变。
在独立工作在免授权频段的系统中,如果仍然采用现有的固定系统带宽及中心频点的方式,尽管可以支持独立工作模式,但是无法在工作频点受到干扰时进行必要的频率和带宽调整,从而导致用户体验受损。

在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如,部件可以是但不限于,在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示,在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中,部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外,这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据,例如通过信号与其它系统交互的互联网)的 信号通过本地和/或远程进程来通信。

在本发明的一个实施例中,终端处于连接态。所谓连接态是指终端在载波上保持连接。保持连接是指终端与基站之间传输数据,或仅保持与基站的连接而不传输数据。在本发明实施例中,终端在第一载波子集合A的载波上 保持连接,基站通过特定信令在第一载波子集合A的载波上通知终端服务载波由第一载波子集合A变化为第二载波子集合B,即,指示终端由第一载波子集合A的载波跳转至第二载波子集合B的载波上保持连接。其中A∈S,B∈S,A≠B,即,第一载波子集合A和第二载波子集合B均属于预设载波集合S,第一载波子集合A和第二载波子集合B分别包括至少一个载波,第一载波子集合A的载波和第二载波子集合B的载波不完全相同。本发明实施例中,第一载波子集合A的载波和第二载波子集合B的载波不完全相同是指第一载波子集合A中的载波和第二载波子集合B中的载波至少有一个不相同。
终端根据上述信令,从第一时刻T1开始,在第二载波子集合B的载波上保持连接。此时,终端所连接的第二载波子集合B的载波上的所有系统信息与第一载波子集合A的载波的系统信息保持一致。并且,优选地,在第一时刻T1之后,终端通过第二载波子集合B的载波获取系统信息。
图2从处于连接态的终端的角度,示出了本发明实施例的载波跳转的方法200的示意性流程图,该方法200可以包括:
S210,终端在第一载波子集合的载波上接收基站发送的信令,其中,该终端当前在该第一载波子集合的载波上保持连接,该信令用于指示该终端由该第一载波子集合的载波跳转至第二载波子集合的载波上保持连接,该第一载波子集合和该第二载波子集合均属于预设载波集合,该预设载波集合中的任意两个载波的中心频点和/或带宽不相同,该预设载波集合的所有载波共用一套系统信息,该第一载波子集合和该第二载波子集合分别包括至少一个载波,该第一载波子集合的载波和该第二载波子集合的载波不完全相同;
S220,该终端根据该信令,从第一时刻开始,在该第二载波子集合的载波上保持连接。
本发明实施例的载波跳转的方法,设置共用一套系统信息的载波集合,当处于连接态的终端接收到基站指示载波跳转的指令时,在与旧载波同属于一个载波集合的新载波上保持连接,在工作频点受到干扰时进行必要的频率和带宽调整,即可以实现载波的跳转,提高用户体验。
在本发明实施例中,信令中可以包括用于指示第二载波子集合B的载波的第一配置信息。第一配置信息的设计可以有多种,例如,第一配置信息中可以包括用于指示第二载波子集合B的载波的载波索引、中心频点索引或位 图bitmap,等。
在一个具体的例子中,第一配置信息的指示可以如下配置。基站通过广播信息或高层信令预先配置预设载波集合S{S0,S1,……,SM-1}。配置预设载波集合S时,对于每个载波Sj,至少需要配置载波的中心频点。载波的系统带宽可显式配置,也可以预先约定。
第一配置信息指示预设载波集合S中的一个或多个载波,组成第二载波子集合B。第一配置信息可以使用bitmap的方式进行指示。例如:预设载波集合S中包括8个元素{S0,S1,……,S7},若第一配置信息设置为{1,0,0,0,0,1,0,0},表示第二载波子集合B为{S0,S6}。
第一配置信息也可以通过
Figure PCTCN2015097443-appb-000001
(其中,
Figure PCTCN2015097443-appb-000002
表示上取整)个比特指示预设载波集合S中的一个载波索引,M由基站配置或协议约定。例如:预设载波集合S中包括8个元素{S0,S1,……,S7},
Figure PCTCN2015097443-appb-000003
调频载波指示域的映射关系如表1所示。若第一配置信息设置为{0,0,01,1,0},表示第二载波子集合B为{S0,S6}。
表1 调频载波指示域的映射关系
调频载波指示域(a2,a1,a0) 指示载波
0,0,0 S0
0,0,1 S1
0,1,0 S2
0,1,1 S3
1,0,0 S4
1,0,1 S5
1,1,0 S6
1,1,1 S7
在另一个具体的例子中,基站通过广播信息或高层信令预先配置中心频点集合F{f0,f1,……,fM-1}。集合F中各元素互不相同。通过由两部分信息组合而成的信令指示一个载波,即选自集合F的中心频点和对应的系统带宽。第一配置信息中可以包括一个或多个上述组合信令。其中,中心频点可以使用bitmap的方式进行指示。也可以通过
Figure PCTCN2015097443-appb-000004
个比特指示集合F中的一个中心频点索引,M由基站配置或协议约定。具体实现过程与上一例子1中的实现过程类似,此处不再赘述。
在本发明实施例中,信令可以承载于广播信道、物理下行控制信道(Physical Downlink Control Channel,PDCCH)的公共搜索空间(Common Search Space,CSS)中的下行控制信息(Downlink Control Information,DCI)、增强物理下行控制信道(Enhanced Physical Downlink Control Channel,EPDCCH)的CSS中的DCI、PDCCH的UE专属搜索空间(UE-specific Search Space,USS)中的DCI、EPDCCH的USS中的DCI、专用物理信道、媒体访问控制(Media Access Control,MAC)层的报头、MAC层的控制单元(Control Element,CE)、无线资源控制(Radio Resource Control,RRC)层的系统信息和RRC层的专用信令中的至少一种中。
具体而言,第一配置信息通过DCI承载的具体方案可以如下。第一配置信息可以通过CSS中的DCI承载。DCI通过专用无线网络临时标识(Radio Network Tempory Identity,RNTI)加扰,其中,专用RNTI由基站配置。DCI的比特长度与现有的DCI format 1A或DCI format 1C相同。配置信息也可以通过USS中的DCI承载。应理解,本发明实施例中DCI还可用于调度物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)等,本发明实施例对此不作限定。
第一配置信息通过专用物理信道承载时,终端根据协议约定的方式确定专用物理信道所占用的物理资源,该物理资源可能与系统带宽或者基站配置部分参数有关,但不需要通过显式的信令通知具体的资源位置。例如使用类似LTE版本8(Release 8,Rel-8)中的物理混合自动重传指示信道(Physical Hybrid ARQ Indicator Channel,PHICH)、物理控制格式指示信道(Physical Control Format Indicator Channel,PCFICH)的物理资源确定方法。
通过专用物理信道承载第一配置信息与通过DCI承载第一配置信息相比的主要优势在于:由于基站完成对其它载波LBT检测的时间与完成数据调度(即完成现有各物理信道资源映射)的时间不同,第一配置信息使用独立的专用物理信道承载,可以保证将第一配置信息尽快的发送下去而不影响其它物理信道的传输。
第一配置信息通过MAC层承载时,可以通过MAC层的报头(MAC header)进行承载。此外,MAC header还可以传输该MAC层的协议数据单元(Protocol Data Unit,PDU)相关的各种信息,例如逻辑信道类型、逻辑 信道号等,本发明实施例对此不作限定。第一配置信息还可以通过MAC层的CE进行承载,MAC CE还可以传输缓冲状态报告(Buffer Status Report,BSR)、跟踪区(Tracking Area,TA)信息等,本发明实施例对此不作限定。
第一配置信息通过RRC层承载时,可以通过RRC层的系统信息进行承载,如通过现有的系统信息块(System Information Block,SIB)消息,或者新的SIB消息进行承载。第一配置信息还可以通过RRC层的专用信令进行承载,如RRC重配置信令、RRC连接释放信令等,本发明实施例对此不作限定。
除上述方法外,第一配置信息指示方法还可以采用EAFCN指示的方式,指示第二载波子集合B中各载波的中心频点与系统带宽。模式如下:
ARFCN 1,Bandwidth1;
ARFCN 2,Bandwidth2;
ARFCN 3,Bandwidth3;
……
终端确定第一时刻T1的具体可以如下。S210,该终端在第一载波子集合的载波上接收基站发送的信令,可以包括:该终端在该第一载波子集合A的载波上的子帧n中接收该基站发送的该信令,其中,n为子帧索引号。S220,终端根据信令,从第一时刻T1开始,在第二载波子集合B的载波上保持连接,可以包括:终端根据信令,从子帧n+N开始,在第二载波子集合B的载波上保持连接,其中,N为正整数。
应理解,本发明实施例的N为常数;或N为根据约定规则确定的;或N为基站配置的。
可选地,作为一个实施例,N为根据约定规则确定的,方法200还可以包括:
该终端确定该基站在连续P个子帧内传输数据,其中,P为正整数;
S210终端在第一载波子集合的载波上接收基站发送的信令,可以包括:
该终端在该第一载波子集合的载波上的子帧n中接收该基站发送的该信令,其中,该子帧n为该连续P个子帧内的一个子帧;
S220该终端根据该信令,从第一时刻开始,在该第二载波子集合的载波上保持连接,可以包括:
该终端判断子帧n+Q是否为该连续P个子帧内的一个子帧,其中,Q 为正整数且Q为常数;
当该子帧n+Q不是该连续P个子帧内的一个子帧时,确定该子帧n+N为该子帧n+Q;
当该子帧n+Q是该连续P个子帧内的一个子帧时,确定该子帧n+N为该连续P个子帧之后的第C个子帧,其中,C为正整数且C为常数;
该终端从该子帧n+N开始,在该第二载波子集合的载波上保持连接。
具体而言,Q的物理意义是系统处理时延,即Q与系统处理时延相关;C的物理意义是调频处理时延,即C与调频处理时延相关。基站确定占用连续P个子帧进行数据传输,子帧n为连续P个子帧中的一个。基站根据系统处理时延对应的子帧数Q,判断子帧n+Q是否为该连续P个子帧内的一个子帧。若子帧n+Q不是该连续P个子帧内的一个子帧时,则基站确定该子帧n+N为该子帧n+Q;若子帧n+Q是该连续P个子帧内的一个子帧时,则基站确定子帧n+N为连续P个子帧之后的第C个子帧。终端从子帧n+N开始在第二载波子集合B上连续传输多个子帧保持连接。即,基站在跳转之后,继续在新的载波上保持跳转之前的连接状态。
在一个具体的例子中,原载波与新载波上用于数据传输子帧数量可以为P。如图3A所示为完成载波切换需要空闲若干符号(例如正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号)的情况。图3B所示为完成载波切换需要空闲一个子帧的情况。应理解,图3A和图3B仅为示意性的,不对本发明实施例造成限定。
在另一个具体的例子中,基站确定占用连续P个子帧进行数据传输,子帧n为连续P个子帧中的一个,则子帧n+N为连续P个子帧之后的第C个子帧。优选地,为连续P个子帧之后的第一或第二个子帧。如图4A所示为完成载波切换需要空闲若干符号的情况。图4B所示为完成载波切换需要空闲一个子帧的情况。应理解,图4A和图4B仅为示意性的,不对本发明实施例造成限定。
在本发明实施例中,方法200还可以包括:
该终端确定该基站在连续P个子帧内传输数据,其中,P为正整数,该子帧n和该子帧n+N为该连续P个子帧内的子帧;
该终端根据该信令,从子帧n+N开始,在该第二载波子集合的载波上保持连接,包括:
该终端从该子帧n+N开始,在该第二载波子集合的载波上检测该基站发送的信号或物理信道,确定该基站是否占用该第二载波子集合的载波进行数据传输;或
该终端从该子帧n+N开始,在该第二载波子集合的载波上检测下行控制信息DCI和/或传输数据,直至该P个子帧结束;或
该终端从该子帧n+N开始,在该第二载波子集合的载波上检测DCI和/或传输数据,直至P+E个子帧结束,其中,E为非负整数,E的取值与调频需要的时域空闲资源的长度相关;或
该终端在该子帧n+N内,在该第二载波子集合的载波上接收该基站发送的第二配置信息,该第二配置信息用于指示该基站从该子帧n+N开始连续传输的子帧数量为T,其中,T为正整数,该终端从该子帧n+N开始,在该第二载波子集合的载波上检测DCI和/或传输数据,直至该T个子帧结束。
在本发明的另一个实施例中,终端处于空闲态。所谓空闲态是指终端在载波上驻留。在本发明实施例中,终端在第一载波子集合A的载波上驻留。在第二时刻T2(空闲态终端可以接收信令的时刻,如广播信令调度时刻或者寻呼消息接收时刻),基站通过特定信令在第一载波子集合A的载波上通知终端服务载波由第一载波子集合A变化为第二载波子集合B,即,指示终端由第一载波子集合A的载波跳转至第二载波子集合B的载波上驻留。其中A∈S,B∈S,A≠B。关于A、B和S的理解,同终端处于连接态的实施例的情况一致,此处不再进行赘述。
终端根据上述信令,从第一时刻T1开始,在第二载波子集合B的载波上驻留。此时,终端所连接的第二载波子集合B的载波上的所有系统信息与第一载波子集合A的载波的系统信息保持一致。并且,优选地,在第一时刻T1之后,终端通过第二载波子集合B的载波获取系统信息。
图5从处于空闲态的终端的角度,示出了本发明实施例的载波跳转的方法500的示意性流程图,该方法500可以包括:
S510,终端在第一载波子集合的载波上的第二时刻接收基站发送的信令,其中,该终端当前在该第一载波子集合的载波上驻留,该信令用于指示该终端由该第一载波子集合的载波跳转至第二载波子集合的载波上驻留,该第一载波子集合和该第二载波子集合均属于预设载波集合,该预设载波集合中的任意两个载波的中心频点和/或带宽不相同,该预设载波集合的所有载波共用 一套系统信息,该第一载波子集合和该第二载波子集合分别包括至少一个载波,该第一载波子集合的载波和该第二载波子集合的载波不完全相同;
S520,该终端根据该信令,从第一时刻开始,在该第二载波子集合的载波上驻留。
本发明实施例的载波跳转的方法,设置共用一套系统信息的载波集合,当处于空闲态的终端接收到基站指示载波跳转的指令时,在与旧载波同属于一个载波集合的新载波上驻留,在工作频点受到干扰时进行必要的频率和带宽调整,即可以实现载波的跳转,提高用户体验。
在本发明实施例中,第二时刻T2对应于系统信息的发送子帧;和/或第二时刻T2对应于寻呼信道的发送子帧。第二时刻T2可以是空闲态终端可以接收信令的一系列时刻。
在一个实施例中,基站在实行载波跳转前,通过系统消息下发信令。该信令中可以包括用于指示第二载波子集合B的载波的配置信息。同时,信令中还可以包括用于指示第一时刻T1的信息。该第一时刻T1可以通过显式的方式通过信令配置到终端,也可以通过隐式约定的方式,由终端与基站提前约定跳转时间,如若干个子帧之后。
应理解,在空闲态终端的实施例和连接态终端的实施例中均使用了第一时刻的描述,两个实施例的第一时刻可以相同,也可以不同,本发明实施例对此不作限定。
基站在实行载波跳转前和/或载波跳转后,可以通过寻呼信道,或可以通过寻呼信道的发送子帧中的PDCCH的公共搜索空间内CSS的下行控制信息DCI,或可以通过寻呼信道的发送子帧中的增强物理下行控制信道EPDCCH的CSS内的DCI承载信令。该信令中可以包括用于指示第二载波子集合B的载波的第一配置信息。同时,信令中还可以包括用于指示系统信息所属的小区的信息。该小区的信息可以包括物理小区标识(Physical Cell Identifier,PCI)、E-UTRAN小区全局标识(E-UTRAN Cell Global Identifier,ECGI)等,以区分原驻留频段接入的其它小区发送的各信令或数据。其中,E-UTRAN为进化型的统一陆地无线接入网络(Evolved UTRAN=Evolved Universal Terrestrial Radio Access Network)。
更具体地,信令的发送可以通过下述方式中的一种或多种的组合来实现。当该第二时刻对应于广播信道的发送子帧时,该基站通过该广播信道发送该 信令;当该第二时刻对应于该系统信息的发送子帧时,该基站通过系统信息发送该信令;当该第二时刻对应于寻呼信道的发送子帧时,该基站通过该寻呼信道、物理下行控制信道PDCCH的公共搜索空间CSS内的下行控制信息DCI和寻呼信道的发送子帧中的增强物理下行控制信道EPDCCH的CSS内的DCI中的至少一种发送该信令。
如上文该,第一配置信息可以承载于系统信息、寻呼信道和寻呼信道的发送子帧的CSS的DCI中的至少一种中。与连接态的终端的实施例类似地,第一配置信息中可以包括用于指示该第二载波子集合的载波的载波索引、中心频点索引或位图bitmap。
