本申请主张在2017年6月19日在中国提交的中国专利申请号No.201710464486.8的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种确定下行控制信道资源的方法、装置、用户设备及基站。
背景技术
移动互联网正在颠覆传统移动通信业务模式,为用户提供前所未有的使用体验,深刻影响着人们工作生活的方方面面。其中,移动互联网将推动人类社会信息交互方式的进一步升级,为用户提供增强现实、虚拟现实、超高清视频、移动云等更加丰富的业务体验。因此,移动互联网的进一步发展将带来未来移动流量超千倍增长,推动移动通信技术和产业的新一轮变革。
另外,物联网扩展了移动通信的服务范围,从人与人通信延伸到人与物、物与物智能互联,使移动通信技术渗透至更加广阔的行业和领域。未来,移动医疗、车联网、智能家居、工业控制、环境监测等将会推动物联网应用爆发式增长,数以千亿的设备将接入网络,实现真正的“万物互联”。同时,海量的设备连接和多样化的物联网业务也会给移动通信带来新的技术挑战。
因此,随着新的业务需求的持续出现和丰富,对未来移动通信系统提出了更高的性能需求,例如更高的峰值速率、更好的用户体验速率、更小的时延、更高的可靠性、更高的频谱效率和更高的能耗效率等,并需要支持更多的用户接入以及使用各种业务类型。因此,终端可能需要同时支持多种传输模式,多种场景,更多样的业务类型。进而对终端的复杂性和耗电要求也更加严苛。
例如,如果终端需要在整个传输带宽上监听下行控制信道,则对于终端能耗的控制将带来极大的挑战,并会增加终端侧的时延。另一方面,对于资 源利用率要求的提高以及未来一些应用场景的需求(例如频域小区间干扰协调),需要更加灵活的配置下行控制信道的传输资源。
其中,对于相关技术中的LTE系统的下行控制信道中的物理下行控制信道(PDCCH)和增强物理下行控制信道(EPDCCH)的介绍如下:
对于PDCCH,其用于承载调度信息以及其他控制信息。每个下行子帧的控制区域内可以有多个PDCCH,控制区域的大小由物理控制格式指示信道(PCFICH)决定,占1~4个正交频分复用(OFDM)符号。一个控制信道的传输占用一个控制信道元素(control channel element,CCE)或者多个连续的CCE,每个CCE由9个资源元素组(resource element group,REG)组成,且PDCCH的CCE所包含的REG为没有用于承载PCFICH和物理混合自动重传指示信道(PHICH)的REG。PDCCH支持多种格式(format)以适应不同的需求,具体支持的format如表1所示。
表1:PDCCH支持的format
PDCCH format CCE的数量 REG的数量 PDCCH的信息比特数
0 1 9 72
1 2 18 144
2 4 36 288
3 8 72 576
其中,用户设备在不是非连续接收(Discontinuous reception,non-DRX)子帧监听PDCCH候选(candidate)集合,即根据所要监听的下行控制信息(DCI)的format来尝试解码搜索空间中的每一个PDCCH。搜索空间分为用户设备专用(UE-specific)和小区专用(Cell-specific),不同搜索空间内可能的PDCCH candidate数量如表2所示。
表2:一个用户设备监听的PDCCH candidates

其中,聚合等级L∈{1,2,4,8}的搜索空间
Figure PCTCN2018091548-appb-000003
由多个PDCCH candidate组成,一个PDCCH candidate所对应的CCE编号由如下公式给出:
Figure PCTCN2018091548-appb-000004
其中,m=0,…,M (L)-1;i=0,…,L-1;N CCE,K为子帧k内用于承载PDCCH的CCE个数,Y k定义为Y k=(A*Y k-1)modD,其中,Y -1≠n RNTI≠0,A=39827,D=65537,
Figure PCTCN2018091548-appb-000005
n s为一个无线帧内slot的编号。
基站在为PDCCH分配资源时,需要避免不同PDCCH之间的冲突,即当某个CCE或某几个CCE已经被PDCCH占用,则不再把该CCE分配给其他PDCCH。
对于EPDCCH,其在子帧中的数据区域进行传输,不能占用PDCCH的传输空间。与PDCCH类似,引入了增强资源单元组(EREG)与增强控制信道元素(ECCE)的概念,具体描述如下:
对于EPDCCH盲检次数的划分,采用协议预约的方式定义,按照场景分别给出E-PDCCH candidate划分的表格。
EPDCCH搜索空间的公式定义为:
Figure PCTCN2018091548-appb-000006
其中,b=n CI,当进行本载波调度的时候n CI=0,在进行跨载波调度的时候,n CI为载波指示信息;
其中,p为物理资源块集合(PRB-set),L为聚合等级,
Figure PCTCN2018091548-appb-000007
Figure PCTCN2018091548-appb-000008
其中,Y p,-1≠n RNTI≠0,A 0=39827,A 1=39829,D=65537,
Figure PCTCN2018091548-appb-000009
总之,在LTE系统中,控制区域在一个子帧中所占的资源位置:对于PDCCH而言,其控制区域占一个子帧内的前N个OFDM符号,N由PCFICH确定,并在频域上占据整个调度带宽;对于EPDCCH而言,其控制区域由高层配置的PRB set确定。
然而,在未来移动通信系统中,用于传输用户设备的专用(UE-specific)的控制资源集合(CORESET)通过无线资源控制信令(RRC signaling)进行配置。但是,当终端未建立RRC连接,并向连接态转换时,其UE-specific PDCCH的资源集合如何确定,即调度第一个RRC signaling的UE-specific PDCCH的资源集合如何确定,当前并没有明确的方案,从而导致未来移动通信系统中下行控制信道的传输资源的配置不够灵活。

具体地,本公开的一些实施例提供了一种确定下行控制信道资源的方法,解决了相关技术中无法为未建立RRC连接的用户设备配置用于传输专用物理下行控制信道的资源集合的问题。
如图1所示,本公开的一些实施例提供了一种确定下行控制信道资源的方法,具体包括以下步骤:
步骤11:接收基站发送的指示消息,并根据所述指示消息确定用于传输用户设备的专用物理下行控制信道的第一资源集合;或者
步骤12:根据协议定义,确定用于传输用户设备的专用物理下行控制信道的第一资源集合。
本公开实施例的确定下行控制信道资源的方法,应用于用户设备。其中,所述用户设备未建立RRC连接,因而基站无法通过RRC信令为未建立RRC连接的所述用户设备配置用于传输专用物理下行控制信道的资源集合。
根据本公开的一些实施例,可以通过基站指示的方式或者预先定义的方式,确定用于传输用户设备的专用物理下行控制信道的资源集合。因而,应用本公开的一些实施例,可以为未建立RRC连接尚未建立RRC连接的用户设备通过基站指示的方式或者预先定义的方式,配置用于传输用户设备的专用物理下行控制信道的资源集合,实现了资源的灵活配置。
其中,所述指示消息为用户设备未建立RRC连接之前可以接收到的基站发送的消息,并且在该指示消息中携带有用于传输用户设备的专用物理下行 控制信道的第一资源集合的指示信息,从而使得用户设备可以从其建立RRC连接之前接收到的指示消息中携带的第一资源集合的指示信息,确定出自身传输专用物理下行控制信道的第一资源集合。
另外,上述协议定义中包括为用户设备配置的专用物理下行控制信道的第一资源集合的指示信息。因而,对于尚未建立RRC连接的用户设备,可以默认采用协议定义中规定的第一资源集合去传输自身的专用物理下行控制信道。
进一步地,确定用于传输用户设备的专用物理下行控制信道的第一资源集合之后,所述方法还包括:在所述第一资源集合内,检测所述用户设备的专用物理下行控制信道。
即对于尚未建立RRC连接的用户设备,通过步骤11或者步骤12确定出用于传输专用物理下行控制信道的第一资源集合之后,可以在该第一资源集合内,检测接收自身的专用物理下行控制信道上传输的控制信息,从而使得尚未建立RRC连接的用户设备可以成功的接收到RRC信令。
其中,在所述第一资源集合中,检测所述用户设备的专用物理下行控制信道的过程,具体如下:
用户设备根据期望接收的下行控制信息格式(DCI format),在所述第一资源集合内的UE-specific搜索空间内,盲检自身的DCI,并根据使用自身标志加扰的循环冗余校验(CRC)对于接收到的DCI进行校验。如果校验成功,则对所述DCI中的信息域进行解析,从而获得所述DCI中携带的控制信息。
进一步地,在所述第一资源集合内,检测所述用户设备的专用物理下行控制信道的步骤之后,所述方法还包括:在检测到的所述用户设备的专用物理下行控制信道上,接收所述用户设备接入网络之后的首个无线资源控制信令的调度信息;根据所述首个无线资源控制信令的调度信息,接收所述首个无线资源控制信令,其中,所述首个无线资源控制信令中携带有所述基站为所述用户设备配置的专用物理下行控制信道的第二资源集合的配置信息。
其中,用户设备在第一资源集合中检测到用户设备的专用物理下行控制信道后,接收该信道上传输的控制信息。其中,该信道上传输的控制信息包括用于调度用户设备接入网络之后的首个RRC信令的调度信息,该调度信息 可以指示用户设备如何去接收用户设备接入网络之后基站发送的首个RRC信令。
另外,由于用户设备接入网络后,基站发送的首个RRC信令中携带有基站重新为该用户设备配置的用于传输该用户设备的专用物理下行控制信道的第二资源集合的配置信息,所以,用户设备根据接收到的首个RRC信令的调度信息,则可以获取到首个RRC信令中携带的第二资源集合的配置信息,进而根据第二资源集合的配置信息确定出第二资源集合。
因此,由上述可知,对于步骤11或者步骤12中确定的第一资源集合还可用于调度用户设备接入网络后基站发送的首个RRC信令,以便于用户设备可以接收到基站为其重新配置的专用物理下行控制信道的第二资源集合。
进一步地,根据所述首个无线资源控制信令的调度信息,接收所述首个无线资源控制信令的步骤之后,所述方法还包括:根据接收到的所述首个无线资源控制信令中携带的所述第二资源集合的配置信息,确定所述第二资源集合;在所述第二资源集合内,检测接收所述用户设备的专用物理下行控制信道上传输的控制信息。
可选的,步骤11包括:接收所述用户设备随机接入过程中所述基站发送的消息,并根据该消息中携带的所述第一资源集合的指示信息确定所述第一资源集合。进一步地,所述用户设备随机接入过程中所述基站发生的消息为Msg2或Msg4。
即在用户设备的随机接入过程中,基站就可以将第一资源集合的指示信息携带在发送给用户设备的其中一个消息中,来将第一资源集合告知给用户设备。
可选的,步骤11包括:接收所述基站发送的RMSI消息,并根据所述RMSI消息中携带的所述第一资源集合的指示信息确定所述第一资源集合;其中,所述RMSI消息为系统消息中除去MIB消息之外的其他系统消息。
其中,所述RMSI消息对所有用户设备均有效,因此通过RMSI消息配置的第一资源集合对于所有成功接收到RMSI消息的用户设备共享。
可选的,步骤11包括:接收所述基站发送的MIB消息,并将从所述MIB消息中获得的用于传输公共控制信道的资源集合确定为所述第一资源集合。 即可以将用于传输公共控制信道的资源集合直接当作第一资源集合来使用。
可选的,步骤12包括:在协议定义中,根据所述用户设备的无线网络临时标识确定所述第一资源集合的起始位置信息;根据所述第一资源集合的起始位置信息,以及预先获得的所述第一资源集合的大小,确定所述第一资源集合。
其中,在预先协议定义中按照各个用户的无线网络临时标识(RNTI)划分各个用户设备的第一资源集合的起始位置,从而使得用户设备可以直接根据自身的RNTI在协议定义中查找到自己的第一资源集合的起始位置。进而结合预先获得的第一资源集合的大小,确定出所述第一资源集合。
另外,预先获得的所述第一资源集合的大小是在所述协议定义中预先定义的;或者预先获得的所述第一资源集合的大小是所述用户设备从所述用户设备随机接入过程中所述基站发送的消息中获得的,或者是所述用户设备从所述基站发送的RMSI消息或MIB消息中获得的;其中,所述RMSI消息为系统消息中除去MIB消息之外的其他系统消息。进一步地,所述用户设备随机接入过程中所述基站发送的消息为Msg2或Msg4。
即所述第一资源集合的大小可以采用预先定义的方式确定,也可以通过显示信令的方式通知用户设备。该显示信令的具体方式可采用:Msg2、Msg4、RMSI消息、MIB消息中的任意一种。
综上所述,用于传输用户设备的专用物理下行控制信道的第一资源集合的确定方式,可采用协议定义或者显示信令的方式,其中,该显示信令具体方式可采用:Msg2、Msg4、RMSI消息、MIB消息中的任意一种。由此可知,本公开实施例中,确定用于传输用户设备的专用物理下行控制信道的第一资源集合的方式,非常灵活。
如图2所示,本公开的一些实施例提供了一种确定下行控制信道资源的方法,具体包括以下步骤:
步骤21:向用户设备发送指示消息,所述指示消息用于指示所述用户设备确定用于传输所述用户设备的专用物理下行控制信道的第一资源集合。
本公开实施例的确定下行控制信道资源的方法,应用于基站。其中,对于未建立RRC连接的用户设备,基站无法通过RRC信令方式为未建立RRC连 接的用户设备配置用于传输专用物理下行控制信道的资源集合。
根据本公开的一些实施例,基站可以通过指示的方式,确定用于传输用户设备的专用物理下行控制信道的资源集合。因而,应用本公开的一些实施例,可以为未建立RRC连接的用户设备通过基站指示的方式,配置用于传输用户设备的专用物理下行控制信道的资源集合,实现了资源的灵活配置。
其中,所述指示消息为用户设备进入连接态之前可以接收到的基站发送的消息,并且在该指示消息中携带有用于传输用户设备的专用物理下行控制信道的第一资源集合的指示信息,从而使得即使用户设备未建立RRC连接,也可以从其进入连接态之前接收到的指示消息携带的第一资源集合的指示信息,确定出自身传输专用物理下行控制信道的第一资源集合。
进一步地,步骤21之后,还包括:
在所述用户设备的专用物理下行控制信道上,向所述用户设备发送所述用户设备接入网络之后的首个无线资源控制信令的调度信息,以使得所述用户设备在确定的所述第一资源集合中,检测所述用户设备的专用物理下行控制信道,接收所述首个无线资源控制信令的调度信息;
为所述用户设备配置用于传输所述用户设备的专用物理下行控制信道的第二资源集合;
将所述第二资源集合的配置信息作为所述首个无线资源控制信令的携带信息发送给所述用户设备。
其中,用户设备根据基站发送的指示消息,确定出用于传输其自身的专用物理下行控制信道的第一资源集合后,会在该第一资源集合内,检测接收自身的专用物理下行控制信道上传输的控制信息,从而使得用户设备可以从该控制信息中获取到用于调度用户设备接入网络之后的首个无线资源控制信令的调度信息,进而根据该调度信息去接收基站发送的携带有基站为用户设备重新配置的用于传输用户设备的专用物理下行控制信道的第二资源集合的配置信息的首个RRC信令。
因此,由上述可知,对于步骤21中基站指示给用户设备的第一资源集合还可用于调度用户设备接入网络后基站发送的首个RRC信令,以便于用户设备可以接收到基站为其重新配置的专用物理下行控制信道的第二资源集合。
进一步地,所述将所述第二资源集合的配置信息作为所述首个无线资源控制信令的携带信息发送给所述用户设备的步骤之后,所述方法还包括:在所述第二资源集合内,传输所述用户设备的专用物理下行控制信道上的控制信息。
可选的,步骤21包括:将所述第一资源集合的指示信息作为所述用户设备随机接入过程中基站发送给所述用户设备的消息的携带信息发送给所述用户设备。进一步地,所述用户设备随机接入过程中基站发送的消息为Msg2或Msg4。
即在用户设备的随机接入过程中,基站就可以将第一资源集合的指示信息携带在发送给用户设备的其中一个消息中,来将第一资源集合告知给用户设备。
可选的,步骤21包括:将所述第一资源集合的指示信息作为RMSI消息的携带信息发送给所述用户设备;其中,所述RMSI消息为系统消息中除去MIB消息之外的其他系统消息。
其中,所述RMSI消息对所有用户设备均有效,因此通过RMSI消息配置的第一资源集合对于所有成功接收到RMSI消息的用户设备共享。
可选的,步骤21包括:向所述用户设备发送MIB消息,以使得所述用户设备将从所述MIB消息中获得的用于传输公共控制信道的资源集合确定为所述第一资源集合。即基站通过MIB消息将用于传输公共控制信道的资源集合告知给用户设备,以使得用户设备可以将用于传输公共控制信道的资源集合直接当作第一资源集合来使用。
可选的,上述方法还包括:将所述第一资源集合的大小作为RMSI消息,或MIB消息,或所述用户设备随机接入过程中基站发送的消息的携带信息发送给所述用户设备,以使得所述用户设备根据所述第一资源集合的大小以及在协议定义中根据所述用户设备的无线网络临时标识确定的所述第一资源集合的起始位置信息,确定所述第一资源集合。进一步地,所述用户设备随机接入过程中基站发送的消息为Msg2或Msg4。
即对于用于传输用户设备的专用物理下行控制信道的第一资源集合,用户设备还可采用协议定义的方式进行确定。其中,需要在预先协议定义中按 照各个用户的无线网络临时标识(RNTI)划分各个用户设备的第一资源集合的起始位置,从而使得用户设备可以直接根据自身的RNTI在协议定义中查找到自己的第一资源集合的起始位置。进而结合预先获得的第一资源集合的大小,确定出所述第一资源集合。
其中,对于第一资源集合的大小,可以使得基站通过显示信令的方式通知给用户设备。即基站将所述第一资源集合的大小,作为RMSI消息,或MIB消息,或所述用户设备随机接入过程中基站发送的消息的携带信息发送给所述用户设备。
综上所述,用于传输用户设备的专用物理下行控制信道的第一资源集合的确定方式,可采用基站通过显示信令通知的方式,其中,该显示信令具体方式可采用:Msg2、Msg4、RMSI消息、MIB消息中的任意一种。由此可知,本公开实施例中,确定用于传输用户设备的专用物理下行控制信道的第一资源集合的方式,非常灵活。
由上述第一实施例和第二实施例可知,本公开实施例的确定下行控制信道资源的方法的具体实施方式可包括如下四种:
第一种:如图3所示,基站将用于传输用户设备的专用物理下行控制信道(UE-specific PDCCH)的第一资源集合的指示信息由随机接入过程中的Msg2或者Msg4携带,使得用户设备在成功接收到Msg2或者Msg4后,可获得其中携带的第一资源集合。其中,用户设备在成功接收到RRC信令之前,需要在第一资源集合内检测接收UE-specific PDCCH,从而使得用户设备可以在UE-specific PDCCH内接收到对用户设备接入网络后基站发送的首个RRC信令的调度信息,进而使得用户设备根据该调度信息接收RRC信令。其中,当终端进入连接状态且成功接收到基站发送的RRC信令之后,则会按照RRC信令中携带的第二资源集合检测接收UE-specific PDCCH。
其中,由于处于连接状态的用户设备,其UE-specific PDCCH资源集合由RRC信令配置,而RRC信令需要通过UE-specific PDCCH进行调度。因此,基站侧需要通过其他方式通知基站调度首个RRC信令的UE-specific PDCCH传输所在的资源集合(即第一资源集合)。本公开的一些实施例中,基站通过Msg2或者Msg4,通知调度首个RRC信令的UE-specific PDCCH传输所在的 资源集合(即第一资源集合)。
第二种:如图4所示,基站通过RMSI配置用于传输UE-specific PDCCH的第一资源集合。用户设备在进入连接态之前,均在RMSI配置的第一资源集合内检测接收自己的UE-specific PDCCH。所述RMSI是对所有用户设备都有效的,因此RMSI配置的第一资源集合对于所有成功接收到RMSI的用户设备共享。直到用户设备进入连接态,并根据在第一资源集合内检测到的UE-specific PDCCH上接收的首个RRC信令的调度信息成功接收到RRC信令后,用户设备则按照RRC信令中配置的第二资源集合检测接收UE-specific PDCCH。
第三种:基站通过MIB消息通知用户设备用于传输公共下行控制信道的资源集合,以使得用户设备可以将该资源集合用作用于传输UE-specific PDCCH的第一资源集合,并在该第一资源集合内检测UE-specific PDCCH,从而根据基站利用UE-specific PDCCH对用户设备RRC信令的调度,去接收基站发送的RRC信令。即用户设备在进入连接态,并成功接收到RRC信令之前,用户设备在由MIB配置的用于传输公共下行控制信道的资源集合内检测接收调度第一个RRC signaling的UE-specific PDCCH。
当用户设备进入连接状态且成功接收到基站发送的RRC信令之后,则会按照RRC信令中携带的第二资源集合检测接收UE-specific PDCCH。
第四种:如图5所示,用户设备在进入连接态,并成功接收到RRC信令之前,用户设备在通过预先定义的方式确定的第一资源集合内检测接收UE-specific PDCCH,从而使得用户设备可以根据基站利用UE-specific PDCCH对用户设备RRC信令的调度,去接收基站发送的RRC信令。当用户设备进入连接状态且成功接收到基站发送的RRC信令之后,则会按照RRC信令中携带的第二资源集合检测接收UE-specific PDCCH。
其中,第一资源集合的起始位置通过用户设备的RNTI确定。第一资源集合的大小可以采用显示信令的方式通知,也可以采用协议定义的方式确定。其中,第一资源集合中包括至少一个控制资源集合(CORESET)。
