背景技术
时分双工(time division duplexing,TDD)是移动通信系统中的一种双工通信技术。TDD系统中,在同一频率信道(即载波)的不同时间内传输上下行信息,通过时间来区分上行信道和下行信道。
随着业务范围的扩大和业务灵活性的提高,通信系统需要支持更多类型的业务数据的传输,这就需要通信系统能够灵活设置上下行子帧,从而灵活传输上下行信息。TDD模式支持对上下行子帧的灵活配置。在TDD模式中,一个帧中的每个子帧均可以被设置为任意一种类型的子帧;其中,按照子帧类型的不同,一个子帧可以是上行子帧、下行子帧或特殊子帧等。在特殊子帧中,部分符号用于传输上行数据,部分符号用于传输下行数据。
由于TDD模式下,一个帧中的每个子帧的类型可以任意设置,因此,对于两个终端设备来说,其中一个终端设备的某个子帧可以被配置为上行子帧,另外一个终端设备的该子帧可以被配置为下行子帧;这样,该两个终端设备中的任一个终端设备在该子帧内传输的信息,例如,公共信息等,受到另一个终端设备在该子帧内传输的信息的干扰较大,可能导致其中一个终端设备在该子帧内传输的公共信息不能被接收端正确接收,从而导致接收端不能利用该公共信息进行工作。例如,终端设备A的该子帧可以被配置为下行子帧,终端设备B的该子帧可以被配置为上行子帧;那么,在该子帧内,终端设备A可能因终端设备B在该子帧内传输上行信息,而不能接收到基站在该子帧内发送的下行控制信息,从而导致终端设备A无法根据下行控制信息正常接入网络。
发明内容
本发明的实施例提供一种子帧配置方法和装置,用以至少解决因“不同终端设备在同一子帧中的信息传输方向相反”而导致的其中一个终端设备在该子帧内传输的公共信息,会受到其他终端设备在该子帧内传输的方向相反的信息的干扰,而导致的接收端(网络设备或终端设备)无法正确接收该公共信息,从而不能利用在该子帧中传输的公共信息进行工作的问题。

本发明实施例还提供了配置目标帧中的第二部分子帧的实现方案,具体的:
可选的,第一方面所提供的方法还可以包括:网络设备向至少两个终端 设备中的至少一个终端设备发送下行控制信息。对应地,第二方面中的发送单元还可以用于:向至少两个终端设备中的至少一个终端设备发送下行控制信息。在该可选的实现方式中,对于第一方面和第二方面来说,向一个终端设备发送的下行控制信息携带网络设备为该终端设备配置的目标帧的第二部分子帧的子帧类型,用于指示该终端设备对目标帧的第二部分子帧的子帧类型进行配置,第二部分子帧是一个帧中除第一部分子帧之外的部分或全部子帧。

本发明实施例还提供了不同网络设备之间不同配置子帧的实现方案,这样,能够减小因其他网络设备下的终端设备在同一个子帧内的传输方向不同,而导致的在该子帧内传输的公共信息不能被接收端接收,从而造成系统性能差的问题。具体的实现方案如下:

下面将结合本发明实施例的说明书附图,对本发明实施例提供的技术方案进行说明。显然,所描述的是本发明的一部分实施例,而不是全部的实施例。需要说明的是,下文所提供的任意多个技术方案中的部分或全部技术特征在不冲突的情况下,可以结合使用,形成新的技术方案。
如图2所示,是本发明实施例提供的一种子帧配置方法的示意图,应用于TDD通信系统,该方法包括S101-S102:
S101:网络设备向至少两个终端设备发送子帧配置消息;子帧配置消息携带目标帧的第一部分子帧的子帧类型,用于指示该至少两个终端设备对目标帧的第一部分子帧的子帧类型进行配置。
本发明实施例对网络设备执行S101的触发条件不进行限定。
“至少两个终端设备”可以是同一个小区内的两个终端设备,也可以是相邻的两个小区(例如,同一基站下相邻的两个小区或不同基站下相邻的两个小区)内的两个终端设备。
“目标帧”可以是网络设备在执行S101时的当前帧之后的任一个待配置的帧。可选的,子帧配置消息中还可以包括目标帧的标识,其中,目标帧的标识可以是目标帧的帧号等。
“第一部分子帧”是指一个帧(即:泛指的“帧”)中的部分子帧,具体是一个帧中特定位置的子帧。本发明实施例对第一部分子帧中子帧的数量,以及这些子帧的位置不进行限定,具体实现时,其可以根据实际应用场景(例如待传输的业务的类型,干扰的强弱等)进行配置。即:一个帧中的哪些子帧作为第一部分子帧可以根据实际场景进行确定。子帧的位置是指子帧在其所在的帧中的位置(例如第3个子帧,第4个子帧等),其可以用子帧号(例如子帧2,子帧3等)来标记。需要说明的是,具体实现时,不同帧的第一部分子帧可以相同也可以不同,例如:帧1的第一部分子帧和帧2的第一部分子帧可以均是:第3个子帧和第4个子帧;帧3的第一部分子帧可以是:第2个子帧和第7个子帧等。
可选的,若目标帧中的第一部分子帧是网络设备与终端设备预先根据协议确定的,且网络设备不需要重新确定第一部分子帧,则子帧配置消息中可以不携带第一部分子帧的标识;若目标帧中的第一部分子帧是网络设备与终端设备预先根据协议确定的,且网络设备需要重新确定第一部分子帧,则子帧配置消息中还可以携带第一部分子帧的标识;或者,若目标帧中的第一部分子帧没有预先确定,则子帧配置消息中还可以携带第一部分子帧的标识。
本发明实施例对第一部分子帧中的每个子帧的子帧类型不进行限定,具体实现时,其可以根据实际应用场景进行配置。例如,第一部分子帧可以包括但不限于表1中的任何一种。其中,在表1中,“*”表示除第一部分子帧之外的其他子帧(包括下文中的第二部分子帧)的子帧类型,其可以是基站根据网络中实际要传输的业务的类型等信息,灵活进行配置的;“D”“U”“S1”“S2”表示第一部分子帧的子帧类型。
表1
Figure PCTCN2017081050-appb-000001
S102:每个终端设备接收网络设备发送的子帧配置消息,并根据子帧配置消息对目标帧的第一部分子帧的子帧类型进行配置;以使在目标帧的第一部分子帧的任一子帧内,该至少两个终端设备进行相同方向的信息传输,相同方向包括上行方向和下行方向中的至少一种。
具体的,若终端设备已经按照协议的规定对目标帧的第一部分子帧的子 帧类型进行了配置,则在S102中,该终端设备可以根据子帧配置消息重新对目标帧的第一部分子帧的子帧类型进行配置,可选的,该终端设备还可以根据子帧配置消息重新确定目标帧中的第一部分子帧。若终端设备还未对目标帧的第一部分子帧的子帧类型进行配置,则在S102中,该终端设备可以直接根据子帧配置消息对目标这的第一部分子帧的子帧类型进行配置。
示例的,若子帧配置消息中携带的信息是表1中的方式0,则该至少两个终端设备中的每个终端设备均将按照表1中的方式0对目标帧中的第一部分子帧的子帧类型进行配置。
在目标帧的第一部分子帧的任一子帧内,所有终端设备进行相同方向的信息传输。示例的,在表1的方式0中,至少两个终端设备在子帧0内均进行下行传输。再如,在表1的方式1中,该至少两个终端设备可以在子帧0(假设共14个符号)的前12个符号内进行下行信息传输,在后2个符号内进行上行信息传输等。又如,在表1的方式2中,该至少两个终端设备在子帧0内均进行下行信息传输,在子帧1内均进行上行信息传输。关于方式3中的S2的示例,与此类似,此处不再赘述。其中,所传输的信息可以包括数据、系统信息、控制信息等中的至少一种。
S103:网络设备在第一部分子帧内传输公共信息。
具体的,网络设备可以在第一部分子帧的上行子帧中传输上行公共信息,例如,基站在第一部分子帧的上行子帧中接收该至少两个终端设备种的至少一个终端设备发送的上行公共信息;或者,网络设备在第一部分子帧的下行子帧中传输下行公共信息,例如,基站在第一部分子帧的下行子帧中向该至少两个终端设备中的至少一个终端设备发送下行公共信息等。
可选的,具体实现时,第一部分子帧还可以用于传输其他信息,例如网络设备在第一部分子帧的上行子帧中传输上行数据,在第一部分子帧的下行子帧中传输下行数据,以及在特殊子帧中传输上下行数据等。
可选的,公共信息可以包括但不限于以下信息中的一种或多种:同步信号,测量参考信号,物理随机接入信道(physical random access channel,PRACH)信息,物理广播信道(physical broadcast channel,PBCH)信息等。其中,同步信息包括主同步信号或辅同步信号;测量参考信号是指用于测量终端设备的信号性能(例如,信号强度,信号质量,信号受到的干扰强度等)的信号;其包括但不限于:小区参考信号(cell reference signal,CRS),SRS等。
需要说明的是,具体实现时,网络设备还可以在第一部分子帧内传输除公共信息之外的其他信息。
本发明实施例提供的子帧配置方法中,通过对目标帧中的部分子帧(即第一部分子帧)的子帧类型进行配置,使得在第一部分子帧的任一子帧内,至少两个终端设备进行相同方向的信息传输,并且,在该第一部分子帧内传输公共信息;这样,能够使该至少两个终端设备中的任一终端设备在传输公共信息的子帧内,另一个终端设备在该子帧内传输相同方向的信息,从而能够减少现有技术中因“不同终端设备在同一子帧中的信息传输方向相反”而 导致的其中一个终端设备在该子帧内传输的公共信息,会受到其他终端设备在该子帧内传输的方向相反的信息的干扰,从而使得接收端(网络设备或终端设备)无法正确接收该公共信息,从而不能利用在该子帧中传输的公共信息进行工作。
可选的,S101-S102可以用以下步骤S1-S2替换:
S1:网络设备向一个簇内的所有终端设备发送子帧配置消息;子帧配置消息携带目标帧的第一部分子帧的子帧类型,用于指示该所有终端设备对目标帧的第一部分子帧的子帧类型进行配置
S2:每个终端设备接收网络设备发送的子帧配置消息,并根据子帧配置消息对目标帧的第一部分子帧的子帧类型进行配置;以使在目标帧的第一部分子帧的任一子帧内,该所有终端设备进行相同方向的信息传输,相同方向包括上行方向和下行方向中的至少一种
其中,一个簇包括一个或多个小区,其中,基站下的小区进行分簇的具体实现方式可以参考现有技术。该情况下,网络设备为同一簇中的所有终端设备配置的第一部分子帧中的任一子帧的子帧类型相同,为不同簇中的终端设备所配置的第一部分子帧的任一子帧的子帧类型可以相同也可以不同。网络设备为不同终端设备配置的第二部分子帧中的任一子帧的子帧类型可以相同也可以不同。
S101-S103提供了为目标帧中的第一部分子帧配置子帧类型的方法,该方法还可以包括为目标帧中的除第一部分子帧之外的其他子帧配置子帧类型。具体的,如图3所示,该方法还可以包括以下步骤S104-S105:
S104:网络设备向该至少两个终端设备中的至少一个终端设备发送下行控制信息;其中,向一个终端设备发送的下行控制信息携带网络设备为该终端设备配置的目标帧的第二部分子帧的子帧类型,用于指示该终端设备对目标帧的第二部分子帧的子帧类型进行配置。
S105:每个终端设备接收到网络设备发送的下行控制信息,并根据该下行控制信息对目标帧的第二部分子帧的子帧类型进行配置。
具体的,对于每个终端设备而言,网络设备可以通过一次或多次发送下行控制信息,从而使得该一次或多次下行控制信息中共携带为该终端设备配置的目标帧的第二部分子帧的子帧类型。第二部分子帧可以是一个帧中除第一部分子帧之外的部分或全部子帧;下文中,均以其是一个帧中除第一部分子帧之外的全部子帧为例进行说明。S105中的下行控制信息可以替换为:L1层中的其他信令,或L2层(即MAC层)层信令。
需要说明的是,具体实现时,S104中的下行控制信息一般是TTI级别的,即:网络设备隔一个或多个TTI发送一次下行控制信息等。
另外需要说明的是,理论上,网络设备可以先执行S101-S103,再执行S104-S105;也可以先执行S104-S105,再执行S101-S103;也可以同时执行S101-S103和S104-S105。实际上,由于S101-S103中是基于小区级进行子帧类型的配置的,而S104-S105中是基于终端设备级进行子帧类型的配置的, 因此,较优的,网络设备先执行S101-S103再执行S104-S105。
可选的,S101可以包括:网络设备向至少两个终端设备发送系统消息或无线资源控制(radio resource control,RRC)信令或下行控制信息。其中,系统消息可以是主系统信息块(master information block,MIB)消息或系统信息块(System information blocks,SIB)消息。需要说明的是,若子帧配置消息是下行控制信息,则该下行控制信息可以是帧级别(例如一个帧或多个帧)的下行控制信息,即网络设备相隔一个帧或多个帧发送一次下行控制信息;而非TTI级别的下行控制信息。
对应地,S102可以包括:每个终端设备接收网络设备发送的系统消息或RRC信令或下行控制信息。
可选的,子帧配置消息具体可以携带但不限于以下任一种信息组合:
组合1:目标帧的第一部分子帧的子帧号,以及子帧号对应的子帧类型。可选的,子帧配置消息中还可以携带第一部分子帧(即第一部分子帧)的子帧数。
示例的,子帧配置消息携带的信息的格式可以包括但不限于:
第一部分子帧的子帧数n;
第一部分子帧1:子帧号x1,子帧类型y1;
第一部分子帧2:子帧号x2,子帧类型y2;
……
第一部分子帧n:子帧号xn,子帧类型yn。
以表1中的方式0为例,子帧配置消息所携带的信息可以是:第一部分子帧的子帧数1;第一部分子帧1:子帧0,D。以表1中的方式3为例,子帧配置消息所携带的信息可以是:第一部分子帧的子帧数2;第一部分子帧1:子帧0,S1;第一部分子帧2:子帧1,S2。
组合2:以bitmap方式指示的目标帧的第一部分子帧的信息,以及目标帧的第一部分子帧的子帧类型。在该可选的方法中子帧类型可以包括但不限于以列表的形式携带在子帧配置消息中。
示例的,假设使用1表示第一部分子帧(即第一部分子帧),使用0表示第二部分子帧(即第二部分子帧);那么,以表1中的方式0为例,子帧配置消息所携带的信息可以是:1000000000,D;以表1中的方式3为例,子帧配置消息所携带的信息可以是:1100000000,S1,S2。
组合3:目标帧的第一部分子帧的子帧号以及以预设数量的比特位指示目标帧的第一部分子帧的子帧类型的信息。
示例的,由于一个帧包括10个子帧,所以可以使用4个比特位表示一个帧中的子帧号,并且假设1个帧中的10个子帧号分别使用“0000-1010”表示。若使用00表示D,01表示U,10表示S1,11表示S2。那么,以表1中的方式0为例,子帧配置消息所携带的信息可以是:0000,00;以表1中的方式3为例,子帧配置消息所携带的信息可以是:0000,0001,10,11。
需要说明的是,上述示例是使用2个比特位表示所有可能的子帧类型的, 具体实现时,网络设备还可以根据该帧内所包含的所有子帧的子帧类型的总数目,并根据该总数目确定表示子帧类型的比特数,即预设数量。例如,以表1中的方式0为例,由于第一部分子帧的类型有1种,若“*”包括U和D共2种,则该总数目是2,那么,预设数量是1。
与上述组合3类似,若第二部分子帧是一个帧中除第一部分子帧之外的全部子帧,则子帧配置消息中还可以具体携带:目标帧的第二部分子帧的子帧号以及以预设数量的比特位指示帧的目标帧的第一部分子帧的子帧类型的信息。该可选的方式尤其适用于第一部分子帧(即第一部分子帧)的数量大于第二部分子帧(包括第二部分子帧)的数量的场景中,其具体示例可以参考上文组合3的具体示例,此处不再赘述。
上文提供了网络设备如何对一个帧中的第一部分子帧的子帧类型进行配置,可选的,该第一部分子帧的子帧类型的配置可以是周期性的。具体的,该方法还可以包括:
S100:网络设备向至少两个终端设备发送携带帧周期T的消息,以指示该所有终端设备在接收到子帧配置消息之后,对从目标帧开始的第nT个帧中的每个帧的第一部分子帧进行配置;其中,T是大于或等于1的整数,n是大于或等于1的整数。
该情况下,S102具体包括:每个终端设备在接收到子帧配置消息之后,对从目标帧开始的第nT个帧中的每个帧的第一部分子帧进行配置,以使在该每个帧的第一部分子帧的任一子帧内,该所有终端进行相同方向的信息传输。
“携带帧周期的消息”可以与S101中的子帧配置消息为同一个消息,也可以为两个独立的消息。较优的,二者是同一个消息,例如,该消息可以是系统消息或RRC信令或下行控制信息等。
示例的,假设目标帧是帧1,T=5,则“从目标帧开始的一个帧周期”具体是:帧1,帧6,帧11,帧16……。“在该每个帧的第一部分子帧的任一子帧内,所有终端进行相同方向的信息传输”,基于前述示例,帧1,帧6,帧11,帧16……内的每个帧的第2个子帧的子帧类型均是U,第3个子帧的子帧类型均是D。
需要说明的是,任意一个或多个帧周期中的非第nT个帧中的第一部分子帧的子帧类型可以与每个帧周期中的第nT个帧中的第一部分子帧的子帧类型相同或不同。例如,基于上述示例,帧2的第2个子帧的子帧类型可以是U,第3个子帧的子帧类型可以是S1等。
该可选的实现方式能够减少网络设备与终端设备之间的信息交互,从而节省带宽。
可选的,该方法还可以包括:网络设备向其他网络设备发送同步配置消息;其中,同步配置消息携带目标帧的第一部分子帧的子帧类型,以指示其他网络设备对其他网络设备下的终端设备进行子帧配置。
“其他网络设备”一般是指与该网络设备相邻的一个或多个网络设备。在该可选的实现方式中,多个网络设备之间可以通过协商,例如,一个基站 主动向相邻基站发送同步配置消息,或在相邻基站的请求下,向该相邻基站发送同步配置消息;接着,该相邻基站可以按照同步配置消息为其下的终端设备进行子帧配置。
该可选的实现方式,可以减小因相邻网络设备下的终端设备在同一个子帧内的传输方向不同,而导致的在该子帧内传输的公共信息不能被接收端接收,从而造成系统性能差的问题。
可选的,基于上文所提供的子帧配置方法,本发明实施例还提供了指示混合自动重传请求(hybrid automatic repeat request,HARQ)的方法,具体如下:
对于下行HARQ时序而言,可选的,该方法还可以包括:网络设备向所有终端设备中的至少一个终端设备发送下行控制信息,其中,发往一个终端设备的下行控制信息携带:网络设备为该终端设备配置的,指示物理下行数据信道的上行反馈所在的子帧(即上行反馈子帧)的信息。具体的,该信息可以是所指示的子帧的标识(例如子帧号,或索引等),也可以是相对于某个子帧的偏移量等。例如,该信息可以子帧n,该情况下,上行反馈子帧是子帧n;该信息还可以是相对于当前下行子帧m的偏移量k;该情况下,上行反馈子帧为子帧m+k。
对于上行HARQ时序而言,可选的,该方法还可以包括:网络设备向所有终端设备中的至少一个终端设备发送下行控制信息,其中,发往一个终端设备的下行控制信息携带网络设备为该终端设备配置的,指示物理上行数据信道的下行反馈所在的子帧(即下行反馈子帧)的信息。具体的,该信息可以是所指示的子帧的标识(例如子帧号,或索引等),也可以是相对于某个子帧的偏移量等。例如,该信息可以子帧n,该情况下,下行反馈子帧是子帧n;该信息还可以是相对于当前下行子帧m的偏移量k;该情况下,下行反馈子帧为子帧m+k。
