本申请要求在2017年7月26日提交中国专利局、申请号为201710619715.9、发明名称为“确定是否继续检测下行控制信道的方法、终端及基站”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域,尤其涉及一种确定是否继续检测下行控制信道的方法、终端及基站。
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。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(3D)视频、移动云等更加丰富的业务体验。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。而物联网则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。
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。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。终端侧的复杂性和耗电要求也更加严苛。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,例如频域小区干扰协调(Inter-Cell Interference Coordination,ICIC),需要更加灵活的配置下行控制信道的传输资源。
在长期演进(Long Term Evolution,LTE)系统中,终端按照期望接收的下行控制信息格式(Downlink Control Information format,DCI format)在公共搜索空间和/或UE-specific搜索空间监听下行控制信道。终端接收到期望接收的DCI format后,则不再继续盲检期望接收的DCI format的下行控制信息(Downlink Control Information,DCI)。在未来的无线移动通信系统中,为了增加传输的可靠性,增加基站覆盖范围等,需要引入基于波束的传输。在需要增强可靠性的场景下,基站需要在不同的波束上发送携带相同信息的DCI format;在需要调度一个终端接收或者发送两个独立的业务信道时,基站需要在不同的波束上发送携带不同调度信息的相同DCI format。对于支持上述两种业务场景的终端,在成功接收到一个指定的DCI forma的一个DCI后,如何确定是否还需要继续按照DCI format进行盲检,现有技术中并没有明确的方案。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
首先对本发明实施例中的部分术语进行简单的介绍,以便本领域技术人员理解。
下行控制信道(Physical Downlink Control CHannel,PDCCH)可以用于承载调度信息以及其他的控制信息。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(Physical Control Format Indicator Channel,PCFICH)决定,占1~4个正交频分复用(Orthogonal Frequency Division Multiplexing,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,且下行控制信道的CCE所包含的REG为没有用于承载PCFICH和PHICH的REG。下行控制信道可 以支持多种DCI format以适应不同的需求。基站在为下行控制信道分配资源时,需要避免不同下行控制信道之间的冲突,即当某个CCE或某几个CCE已经被下行控制信道占用,则不再把该CCE分配给其他下行控制信道。
在未来的无线移动通信系统中,为了增加传输的可靠性,增加基站覆盖范围等,基站需要在不同的波束上向终端发送携带相同信息的DCI format或者基站需要在不同的波束上向终端发送携带不同调度信息的相同DCI format。而终端可以根据其需要的DCI format对DCI进行检测接收。
下面结合附图对本发明优选的实施方式进行详细说明。
实施例一
请参见图1,本发明实施例提供一种确定是否继续检测下行控制信道的方法,可以应用于终端,其中,该方法的过程可以描述如下:
S10:终端获得第一下行控制信息(DCI);
S20:终端基于第一DCI,确定是否继续检测下行控制信道。
S10中,终端可以从基站获得第一DCI,其中,第一DCI可以由下行控制信道承载,下行控制信息(DCI)可以包括上下行资源分配、混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)、功率控制等信息。
可选的,终端可以通过但不仅限于以下两种方式从基站获得第一DCI。
方式一、终端可以在公共下行控制信道(common PUCCH)或者组下行控制信道(group common PDCCH)上获得第一DCI。
此种方式下,第一DCI中可以包含至少一个盲检指示信息,其中,每个盲检指示信息对应一个终端所需DCI format的DCI的个数。
举例来说,若第一DCI中包括盲检指示信息1、盲检指示信息2,则盲检指示信息1可以指示终端A对应的DCI format1的DCI的个数为2;盲检指示信息2可以指示终端B对应的DCI format2的DCI的个数为1。
因此,终端从公共下行控制信道或者组公共下行控制信道获得第一DCI后,可以确定第一DCI中携带的至少一个盲检指示信息中与其对应的第一盲检指示信息,然后终端根据第一盲检指示信息,在一个monitoring ocassion内的UE-specific搜索空间内,按照第一预设DCI format成功接收到一个DCI后,确定是否继续在相同monitoring ocassion内按照所述第一预设DCI format检测下行控制信道。
可选的,monitoring occasion为终端在一个传输时间间隔(Transmission Time Interval,TTI)需要监听的下行控制信道的连续时域资源,终端需要在monitoring occasion上的至少一个控制资源集合(COntrol REsource SET,CORESET)内监听下行控制信道。
以终端A为例,终端A在接收到第一DCI之后,可以根据基站通过无线资源控制(Radio Resource Control,RRC)信令发送的与终端A对应的指示信息域的索引(index),从至少一个盲检指示信息中解析终端A对应的盲检指示信息1,然后终端A就可以根据盲检指示信息1的指示,确定在一个monitoring ocassion内的UE-specific搜索空间内,需要按照第一预设DCI format,即DCI format1在下行控制信道中检测接收2个DCI。也就是说,若终端A成功接收到一个DCI format1的DCI后还得继续在相同monitoring ocassion内按照相同的DCI format1检测下行控制信道。
方式二、终端可以在UE-specific下行控制信道获得第一DCI。
此种方式中,终端获得的第一DCI中可以携带第二盲检指示信息,第二盲检指示信息可以用于指示终端在下行控制信道的相同monitoring occasion内需要接收的与第一DCI具有相同DCI format的DCI的个数。
也就是说,第二盲检指示信息指示的DCI个数可以为包括终端获得的第一DCI在内的DCI的个数,且这些DCI具有相同的DCI format。
比如,第二盲检指示信息指示的DCI的个数为3,由于终端已经在一个monitoring ocassion内的UE-specific搜索空间内接收到第一DCI,因此,终端还需要在相同monitoring ocassion内检测接收与第一DCI具有相同DCI format的两个DCI;或者,若第二盲检指示信息指示的DCI的个数为1,由于终端已经在一个monitoring ocassion内的UE-specific搜索空间内接收到第一DCI,因此,终端不再需要在相同monitoring ocassion内检测接收与第一DCI具有相同DCI format的DCI了。
可选的,盲检指示信息可以由N bit信息域指示,其中,N为大于或等于1的整数,N bit信息域可以作为第一DCI的第一个信息域,或者第二个信息域,或者第三个信息域。盲检指示信息可以根据N bit信息域划分为但不仅限于以下两种状态:
第一状态:可以描述为终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1的状态。
比如,若盲检指示信息由1bit信息域进行指示时,如盲检指示信息可以为0,即盲检指示信息为第一状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1;若盲检指示信息由N>1bit信息域进行指示时,如盲检指示信息由N=2bit信息域进行指示,盲检指示信息的组合可以为00,即盲检指示信息为第一状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1。
第二状态:可以描述为终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为大于1时的状态。
比如,若盲检指示信息由1bit信息域进行指示时,如盲检指示信息可以为1,即盲检指示信息为第二状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数大于1;若盲检指示信息由N>1bit信息域进行指示时,如盲检指示信息由N=2bit信息域进行指示,盲检指示信息的组合可以为01或者10或者11,即盲检指示信息为第二状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数大于1。
可选的,针对前述方式一,当终端确定的第一DCI中携带的至少一个盲检指示信息中与终端对应的第一盲检指示信息为第一状态时,即第一盲检指示信息指示了终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1,那么终端在一个monitoring ocassion内接收到相同DCI format的一个DCI之后,就不再继续检测下行控制信道。
当终端确定的第一DCI中携带的至少一个盲检指示信息中与终端对应的第一盲检指示信息为第二状态时,即第一盲检指示信息指示了终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数大于1,那么终端在一个monitoring ocassion内需要接收的相同DCI format的一个DCI之后,需要继续按照相同DCI format在相同monitoring ocassion中一个CORESET或者其他CORESET内检测接收下行控制信道,直到在下行控制信道中检测接收到2个或者3个或者4个等相同DCI format的DCI。
针对前述方式二,当终端获得的第一DCI中携带的第二盲检指示信息为第一状态时, 即第二盲检指示信息指示了终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1,由于此时终端已经接收到第一DCI,因此终端在下行控制信道monitoring occasion上的其中一个CORESET内成功检测接收到下行控制信道承载的第一DCI后,不再继续按照第一DCI的DCI format在CORESET或者其他CORESET内检测下行控制信道。
当终端获得的第一DCI中携带的第二盲检指示信息为第二状态时,即第二盲检指示信息指示了终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数大于1,由于此时终端仅接收到第一DCI,因此终端在下行控制信道monitoring occasion上的其中一个CORESET内成功检测接收到下行控制信道承载的第一DCI后,需要继续按照第一DCI的DCI format在CORESET或者其他CORESET内检测下行控制信道。
本发明实施例中,为了提高覆盖抵抗高频段的衰减,基站可能需要采用定向波束发送下行控制信道。在不同的应用场景下,如为了增加可靠性,基站可以在不同的波束上发送相同的数据信息,或者基站也可以在不同的波束上发送不同的数据信息,例如来自相同或者不同发送接收节点(Transmission Reception Point,TRP)上的不同波束同时发送不同的下行数据。
比如,基站需要在不同的波束(beam)上发送相同的DCI,以增强下行控制信道的可靠性,如图2所示,基站20分别在beam1和beam2上发送了相同的DCI给终端21;如图3所示,终端21需要同时接收来自TRP30的beam31上承载的数据,及TRP31的beam4上承载的数据,其中,TRP30的beam3和TRP31的beam4上承载的数据不同。
对于图2的场景,终端21在成功接收到所需要的DCI后,不需要按照特定的DCI format在monitoring occasion上的至少一个CORESET内继续盲检PDCCH;对于图3的场景,终端21在成功接收到所需的DCI后,仍需要按照特定的DCI format在monitoring occasion上的至少一个CORESET内继续盲检PDCCH。
比如,终端接收到的第一DCI中携带盲检指示信息,该盲检指示信息由1bit信息域指示。假设在每一个下行控制信道monitoring occasion内基站为终端配置了两个CORESET。不同的CORESET对应不同的beam方向或者一个CORESET对应不同的beam方向。
因此,当盲检指示信息为第一状态时,则终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,不再继续按照特定的DCI format在相同CORESET或者其他CORESET内检测下行控制信道。比如,终端在CORESET1内成功接收到特定的DCI format的DCI,则终端不需要继续在CORESET1以及CORESET2内继续按照特定的DCI format监听下行控制信道。
当盲检指示信息为第二状态时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功接收到下行控制信道承载的特定的DCI format的一个DCI后,需要继续按照特定的DCI format在CORESET或者其他CORESET内检测接收下行控制信道。比如,终端在CORESET1内成功接收到特定的DCI format的DCI,则终端需要继续在CORESET1以及CORESET2内按照特定的DCI format监听下行控制信道,直到对两个CORESET内的所有下行控制信道候选位置(PDCCH candidate)完成检测或者达到了盲检(blind decode)的上限。
或者,如果终端最多可以同时接收来自两个beam上的数据信息,则当盲检指示信息 为第二状态时,基站在成功接收到特定的DCI format的两个DCI后,不再在下行控制信道monitoring occasion上的所有CORESET内继续按照特定的DCI format盲检下行控制信道。当然,终端也可能需要接收多个beam上发送的数据信息。
假设在每一个下行控制信道monitoring occasion内基站为终端配置了多个CORESET,其中,不同的CORESET对应不同的beam方向,或者一个CORESET对应不同的beam方向。基站可以在DCI中携带盲检指示信息,当盲检指示信息可以由N=2bit信息域指示时,如表1所示,盲检指示信息的不同组合可以指示不同的盲检策略。
表1
Figure PCTCN2018097084-appb-000001
表1中,盲检指示信息的组合为00时,盲检指示信息为第一状态,盲检指示信息的组合为01或者10或者11时,盲检指示信息为第二状态。
例如,当盲检指示信息为00时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,不再继续按照该特定的DCI format在相同CORESET或者其他CORESET内检测下行控制信道。
而当盲检指示信息为01时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,需要继续在该CORESET内或者其他CORESET内按照相同的特定的DCI format盲检下行控制信道,直到成功检测到另一个与前述相同的特定的DCI format的DCI以完成对搜索空间的盲检。
当盲检指示信息为10时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功检测接收到下行控制信道承载的所述DCI的一个DCI后,需要继续在该CORESET内或者其他CORESET内按照相同的DCI format盲检下行控制信道,直到成功检测到另外两个特定的DCI format的DCI或者完成对搜索空间的盲检。
当盲检指示信息为11时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照特定的DCI format成功检测接收到下行控制信道承载的所述DCI的一个DCI后,需要继续在该CORESET内或者其他CORESET内按照相同的DCI format盲检下行控制信道,直到成功检测到另外三个相同的特定的DCI format的DCI或者完成对搜索空间的盲检。
当然,在实际应用中,终端期望接收到的相同DCI format的DCI数目可以小于4。例如终端期望接收到的相同DCI format的DCI数目为3,则11可以保留。
可选的,终端基于第一DCI,确定是否继续检测下行控制信道还可以通过但不仅限于 以下两种方式进行:
(a)、首先,终端确定第一DCI的循环冗余校验(Cyclic Redundancy Check,CRC)加扰所使用的第一无线网络临时标志(Radio Network Temporary Identity,RNTI),然后终端基于第一RNTI,确定是否在相同的monitoring ocassion内按照相同的DCI format继续检测下行控制信道。
即终端可以根据基站对第一DCI的CRC进行加扰所使用的RNTI,确定是否继续检测下行控制信道,该过程可以为:
终端确定第一RNTI为具有第一数值的RNTI,终端确定不再继续检测下行控制信道;或者,终端确定第一RNTI为具有第二数值的RNTI,终端确定继续检测下行控制信道,以获得第二下行控制信息DCI。
举例来说,基站可以使用不同的RNTI对第一DCI的CRC进行加扰。例如,基站可以使用X-RNTI对CRC进行加扰,或者基站可以使用Y-RNTI对CRC进行加扰,其中,X-RNTI中的X和Y-RNTI中Y对应不同的数值。即不同数值的RNTI可以对应不同的场景。
假设第一RNTI的第一数值为X,对应终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format需要检测获得的DCI的个数为1;当第一RNTI的第二数值为Y时,对应终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format需要检测获得的DCI的个数大于1,当然,X和Y的具体取值可以根据实际情况进行自定义,本发明实施例不作限制。
因此,若终端确定第一RNTI为具有第一数值的RNTI时,则当终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,终端不再继续按照DCI format在相同CORESET或者其他CORESET内检测下行控制信道;或者,若终端确定所述第一RNTI为具有第二数值的RNTI时,当终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,终端需要继续按照特定的DCI format在相同CORESET或者其他CORESET内检测下行控制信道。
需要说明的是,本发明实施例中还可以引入多个具有不同数值的RNTI对应不同的所需要接收的相同DCI format的个数,本发明实施例对此不作限制。
(b)、终端可以确定第一DCI的下行控制信息格式DCI format;终端可以根据第一DCI的DCI format所属的DCI format集合,确定是否继续在相同的monitoring ocassion内按照相同的DCI format检测下行控制信道。
比如,基站可以为终端配置属于不同DCI format集合的DCI format,终端通过特定的接收的DCI format归属的DCI format集合,确定是否需要在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format成功检测接收到下行控制信道承载的特定的DCI format的一个DCI后,继续按照相同的特定的DCI format在相同CORESET或者不同CORESET内盲检下行控制下信道。
如,引入DCI format集合1以及DCI format集合2,其中,DCI format集合1中至少包含一种DCI format,DCI format集合2中也至少包含一种DCI format。基站可以设定DCI format集合1对应终端在下行控制信道的monitoring occasion上的其中一个CORESET上 按照特定的DCI format需要检测获得的DCI的个数为1,DCI format集合2可以对应终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照特定的DCI format需要检测获得的DCI的个数大于1。
因此,当终端接收到的第一DCI的DCI format属于DCI format集合1时,则终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照第一DCI的DCI format成功检测接收到下行控制信道承载的第一DCI后,终端不再继续按照第一DCI的DCI format在相同CORESET或者其他CORESET内检测下行控制信道。
或者,当终端接收到的第一DCI的DCI format属于DCI format集合2时,终端在下行控制信道的monitoring occasion上的其中一个CORESET上按照第一DCI的DCI format成功检测接收到下行控制信道承载的第一DCI,终端需要继续按照第一DCI的DCI format在相同CORESET或者其他CORESET内检测接收下行控制信道。
实施例二
请参见图4,本发明实施例还提供一种确定是否继续检测下行控制信道的方法,该方法的过程可以描述如下:
S100:终端基于高层信令中携带的第三盲检指示信息,确定在每个监听时间(monitoring ocassion)内需要接收的第二预设下行控制信息格式(DCI format)的DCI的个数;
S200:终端判断在成功接收到第二预设DCI format的一个DCI后,是否继续按照第二预设DCI format在相同的monitoring ocassion内检测下行控制信道。在此种方法中,终端在对下行控制信道进行盲检之前就知道其需要接收的DCI format的DCI的个数。
即,终端的高层信令中携带的第三盲检指示信息,可以指示终端在一个monitoring ocassion内需要接收的第一预设DCI format的DCI的个数,后续终端可以按照第三盲检指示信息指示的第一预设DCI format的DCI的个数对下行控制信道中的DCI进行检测接收。
其中,第三盲检指示信息可以由M bit信息域指示,其中,M为大于或等于1的整数,进而第三盲检指示信息可以根据M bit信息域分为第三状态和第四状态。
第三状态:可以描述为终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1的状态;
比如,若第三盲检指示信息由1bit信息域进行指示时,如第三盲检指示信息可以为0,即第三盲检指示信息为第三状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1;若第三盲检指示信息由M>1bit信息域进行指示时,如第三盲检指示信息由M=2bit信息域进行指示,第三盲检指示信息的组合可以为00,即第三盲检指示信息为第三状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为1。
第四状态:可以描述为终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数为大于1时的状态。
比如,若第三盲检指示信息由1bit信息域进行指示时,如第三盲检指示信息可以为1,即第三盲检指示信息为第四状态,终端在一个monitoring ocassion内需要接收的相同DCI format的DCI的个数大于1;若第三盲检指示信息由M>1bit信息域进行指示时,如盲检指示信息由M=2bit信息域进行指示,第三盲检指示信息的组合可以为01或者10或者11,即第三盲检指示信息为第四状态,终端在一个monitoring ocassion内需要接收的相同DCI  format的DCI的个数大于1。
举例来说,终端可以接收RRC信令中第三盲检指示信息。假设第三盲检指示信息由M=1bit信息域指示时,第三盲检指示信息为第三状态,如第三盲检指示信息为0,则终端在下行控制信道monitoring occasion上的其中一个CORESET内按照第三盲检指示信息指示的DCI format成功检测接收到下行控制信道承载的一个DCI后,不再继续按照相同DCI format在相同CORESET或者其他CORESET内检测下行控制信道。
当第三盲检指示信息为第四状态,如第三盲检指示信息为1时,终端在下行控制信道monitoring occasion上的其中一个CORESET内按照第三盲检指示信息指示的DCI format成功接收到下行控制信道承载的一个DCI后,继续按照相同DCI format在相同CORESET或者其他CORESET内检测接收下行控制信道。
当第三盲检指示信息由M>1bit信息域指示时,如第三盲检指示信息由M=2bit信息域指示时,则不同的信息比特组合如前述实施例一中的相应方法,本发明实施例在此不再赘述。即终端在RRC信令配置周期内均可以按照如上高层信令中携带的第三盲检指示信息对下行控制信道进行盲检。
