为了使本发明的具体技术方案、发明目的更加清楚,下面结合具体的实施方式和附图作进一步清楚、完整地描述,显然,所描述的实施方式仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例的应用场景实施例为:通信系统中存在着至少两种网络,第一网络和第二网络,这两种网络具有不同的调度资源时间粒度,其中,调度资源时间粒度又可以被称为资源调度单位,或者最小调度单元(minimum scheduling unit,MSU),是传输信道的量纲,代表数据的最小传输时间,具体是指无线链路一个能够独立解调的传输块的长度。例如,在长期演进(long term evolution,LTE)网络中为发送时间间隔(transmission time interval,TTI)。第一网络和第二网络的覆盖范围存在重叠。第一网络所支持的第一无线通信技术(radio access technology,RAT)和第二网络所支持的第二RAT可以相同,也可以不同,但第一网络和第二网络所处的载波范围不同。另外,一个基站可以分别为第一网络和第二网络提供服务,或者,由第一基站为第一网络提供服务,由第二基站为第二网络提供服务。
可选的,上述提及的第一基站可以为宏基站,并且第二基站可以为小基站。所述小基站的发射功率和覆盖范围都小于所述宏基站,例如,小基站可以为家庭型演进基站(home evolved NodeB,HeNodeB),微型基站(micro base station),接入点(access point,AP),微微基站(pico base station)等。
可选的,第一网络或者第二网络具体可以是码分多址(code division multiple access,CDMA)、时分多址(time division multiple
access,TDMA)、频分多址(freq终端ncy division multiple access,FDMA)、正交频分多址(orthogonal freq终端ncy-division multiple access,OFDMA)、单载波频分多址(single carrier FDMA,SC-FDMA)和其它网络等。术语“网络”和“系统”可以相互替换。CDMA网络可以实现例如通用无线陆地接入(universal terrestrial radio access,UTRA),CDMA2000等无线技术。UTRA可以包括CDMA(WCDMA)和其他CDMA的变形。CDMA2000可以覆盖临时标准(interim standard,IS)2000(IS-2000),IS-95和IS-856标准。TDMA网络可以实现例如全球移动通信系统(global system for mobile communication,GSM)等无线技术。OFDMA网络可以实现诸如演进通用无线陆地接入(evolved UTRA,E-UTRA)、超级移动宽带(ultra mobile broadband,UMB)、IEEE 802.11(Wi-Fi),IEEE 802.16(WiMAX),IEEE 802.20,Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在LTE和LTE高级(LTE Advanced,LTE-A)是使用E-UTRA的UMTS的新版本。UTRA、E-UTRA、UMTS、LTE、LTE-A和GSM在3GPP标准组织的文档中有记载描述。CDMA2000和UMB在3GPP2标准组织的文档中有记载描述。第一网络或者第二网络还可以是新一代的网络,例如第五代(the fifth generation,5G)网络。
通信系统中还存在着终端,该终端同时属于第一网络和第二网络的覆盖范围,也即,第一网络和第二网络都能够为该终端提供服务。该终端又可以称为用户设备(user equipment,UE)、移动台(mobile station)、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手
持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop,WLL)台等。
举例来说,如图1(a)所示,为第一网络和第二网络的覆盖范围存在重叠,第一网络和第二网络由同一个基站控制,并且终端处于第一网络和第二网络覆盖范围重叠部分的应用场景图;如图1(b)所示,为第一网络和第二网络的覆盖范围存在重叠,第一网络由第一基站提供服务,第二网络由第二基站提供服务,第一基站为宏基站,第二基站为小基站,并且终端处于第一网络和第二网络覆盖范围重叠部分的应用场景图。
由于在第二网络中出现了信息传输超负载,传输可靠性降低等问题,需要在第一网络中协助传输属于第二网络的控制信息对终端进行在第二网络中的资源调度。
例如,可以考虑这样一种场景:为了满足通信系统越来越苛刻的低时延传输需求,在新一代网络或者某些现有的网络中,调度资源时间粒度将被设计的更短。例如,目前LTE网络的调度资源时间粒度(也即,TTI)为1ms,而未来调度资源时间粒度很有可能被设计为小于1ms,如0.1ms,这种调度资源时间粒度的形式若被应用于使用高频频段进行通信的新一代网络当中去,的确可以降低通信系统的传输时延。不过,高频通信容易受到传输环境的影响,因此,利用高频频段进行通信可能导致所传信息的丢失。为了解决以上问题,一种可行的办法是使用低频通信的网络传输使用高频通信的网络的控制信息。
现有技术中,LTE网络已经能够实现载波聚合和跨载波调度的方法来充分利用两个载波的信道资源。例如,使用物理下行公共控制信道(physical downlink common control channel,PDCCH)的方式,或者使
用增强物理下行公共控制信道(enhanced physical downlink common control channel,EPDCCH)的方式实现对主载波和辅载波小区的终端的调度。但是,无论是PDCCH的方式还是EPDCCH的方式,目前都还是同一个网络之间的调度,更重要的是,使用这两种方式实现跨载波调度的前提是这两种载波对应的TTI必须长短一致。
本发明实施中提供的方案能够实现使用低频通信的网络传输使用高频通信的网络的控制信息,从而解决在使用不同调度资源时间粒度的不同网络之间实现跨网络资源调度的问题。
为了解决上述问题,本发明实施例提供了一种基站200,该基站200可以是应用场景实施例中所述的为第一网络和第二网络提供服务的基站,也可以是仅为第一网络提供服务的第一基站。如图2所示,所述基站包括处理单元210和收发单元220。本发明实施例还提供了一种终端300,该终端300可以为应用场景实施例中所述的终端。如图3所示,所述终端包括收发单元310和处理单元320。在本发明实施例中,由于处理单元210和收发单元220包含在所述基站200中,处理单元320和收发单元310包含在所述终端300中,因此,所述处理单元210或者收发单元220所执行的操作都可以视为是所述基站200的操作,所述处理单元320或者所述收发单元310所执行的操作都可以视为是所述终端300的操作。在本发明实施例中,所述基站200中的处理单元210可以由基站200的处理器实现,所述收发单元220可以由基站200中的收发器实现;所述终端300中的处理单元320可以由终端300中的处理器实现,所述收发单元310可以由终端300中的收发器实现。
图4是本发明实施例提供的一种控制信息发送的方法的流程图。该方法可以应用于本发明应用场景实施例,并且由图2发明实施
例中的基站200和图3发明实施例中的终端300配合实现。该方法包括:
S401、基站200确定第一网络中的第一资源,所述第一资源位于所述第一网络的第一调度资源时间粒度中;
为了在第一网络当中传输第二网络的控制信息,基站200需要在第一网络中确定合适的第一资源用于传输该控制信息。该第一资源又可以被称为跨载波调度资源。另外,S401中的“确定”的方式可以为:基站200获取第一网络中的第一资源的配置信息,也可以是基站自主分配第一网络中的第一资源的配置信息,这里不做限制。
可选的,第一资源包括下行资源。当所述第一网络中的资源包括下行资源时,映射到所述第一资源的信道可以和所述第一网络的物理下行共享信道(physical downlink shared channel,PDSCH)频分复用,例如,所述第一网络的第一资源被映射到EPDCCH中。第一网络的PDSCH是用于传输第一网络中的数据的信道,容量比较大,若映射到第一资源的信道实现与PDSCH的频分复用,则可以提高第一网络中信道的利用率。
可选地,基站200的处理单元210用于确定第一网络中的第一资源,所述第一资源位于所述第一网络的第一调度资源时间粒度中。
S402、基站200在所述第一资源上向所述终端发送所述第二网络的下行控制信息。
其中,所述第一资源上所发送的所述下行控制信息用于调度所述第二网络中第一调度资源时间粒度的资源,且所述第一网络的调度资源时间粒度的长度和所述第二网络的调度资源时间粒度的长度不同。
为了实现在第一网络中对第二网络的数据进行调度的目的,基站200在所述第一网络的第一资源上向终端300发送第二网络的下行控
制信息。
如果基站200是为第一网络和第二网络提供服务的基站,那么基站200自身就能够获知第二网络中的所述下行控制信息;如果基站200为只能为第一网络提供服务的第一基站时,基站200获得第二网络中的下行控制信息的方式可以是:基站200接收为第二网络提供服务的第二基站发送的所述下行控制信息,以便将所述下行控制信息通过所述第一资源发送给终端300。
可选的,基站200向终端300发送下行控制信息为下行授权信息。
该下行授权信息中可以包括终端300在第二网络中下行的调度数据对应的资源(包括时域、频域、空域等资源)信息。下行的调度数据对应的资源信息可以包括:频域位置,时域位置或者空域位置。该下行授权信息中可以还可以包括终端300身份标识信息(用于让终端300知道该调度授权信息是否属于自己的信息),调制编码策略(指示终端300的传输数据采用的调试方式和编码方式),冗余版本,新数据指示(指示当前块是新传数据还是重传数据),传输块大小,混合自动重传请求(hybrid automatic repeat request,HARQ)信息(指示当前的HARQ进程号)等。此时,时域上,所述第一资源上承载的所述下行授权信息,由基站200在所述下行授权信息调度的所述第二网络的第一调度资源时间粒度之前或者相同时刻向终端300发送,所述第二网络的第一调度资源时间粒度上承载所述下行授权信息调度的下行数据。
当然,作为一种例外,因为如今的网络已经能够实现下行授权信息稍晚于下行数据发送,所以在极少数的特殊情况下,下行授权信息可以稍晚于第二网络的第一调度资源时间粒度中的下行数据发送。
基站200向终端300发送下行控制信息还可以为上行授权信息,该上行授权信息中可以包括终端300在第二网络中上行的调度数据对应的资源(包括时域、频域、空域等资源)信息。上行的调度数据对应的资源信息可以包括:频域位置,时域位置或者空域位置。该上行授权信息中还可以包括终端300身份标识信息(用于让终端300知道该调度授权信息是否属于自己的信息),调制编码策略(指示终端300的传输数据采用的调试方式和编码方式),冗余版本,新数据指示(指示当前块是新传数据还是重传数据),传输块大小,HARQ信息(指示当前的HARQ进程号)等。此时,时域上,所述第一资源上承载的所述上行授权信息,由所述基站在所述下行授权信息调度的所述第二网络中的第一调度资源时间粒度之前或者相同时刻向所述终端发送,所述第二网络中的第一调度资源时间粒度上承载所述上行授权信息调度的上行数据。
当然,基站200向终端300发送下行控制信息还可以为下行确认应答(acknowledgement,ACK),或者下行否认应答(negative acknowledgement,NACK)。此时,时域上,所述第一资源上承载的所述下行ACK或者下行NACK,由基站200在所述下行ACK或者下行NACK调度的所述第二网络中的第一调度资源时间粒度之后,并且终端300上传与所述第二网络中的第一调度资源时间粒度具有相同混合式自动重传请求标识(hybrid automatic repeat request identity,HARQ ID)的上行数据之前向终端300发送,所述第二网络中的第一调度资源时间粒度上承载所述待所述下行ACK或者下行NACK应答的上行数据。
可选的,当所述第一资源上所发送的下行控制信息为一条时,所述下行控制信息调度的第二网络中的调度资源时间粒度为一个,此
时,所述第一资源对应一个第二网络中的调度资源时间粒度;
当所述第一资源中上所发送的下行控制信息为M条时,所述下行控制信息调度的第二网络中的调度资源时间粒度为M个,其中,M为大于1的正整数。每条下行控制信息调度一个第二网络中的调度资源时间粒度。此时,所述第一资源对应一个第二网络中的调度资源时间粒度为M个。
可选的,所述第一网络的第一调度资源时间粒度中,包括多个所述第一资源,多个所述第一资源组成第一资源集合。
所述第一网络的调度资源时间粒度的长度为所述第二网络的调度资源时间粒度的N倍时,所述第一网络中的第一调度资源时间粒度中可以包括N个所述第一资源。其中,N为大于1的正整数。
为了便于所述领域的技术人员实现,下面提供了几个更为具体的实施例。
图5为本发明提供的一种资源调度的示意图。如图5所示,第一网络的调度资源时间粒度和第二网络的调度资源时间粒度都可以被称作TTI。做为一个举例,第一网络的TTI长于第二网络的TTI,且第一网络的TTI为第二网络的TTI的两倍。第一网络中用于发送第二网络的控制信息的第一资源被映射到的信道与第一网络的PDSCH进行频分复用,一个第一网络中的TTI(这里第一网络中的TTI称为TTIA)包含两个第一资源,这里分别称为RA1和RA2。每个第一资源时域上的长度等于第二网络的TTI,这里第二网络中的TTI称为TTIB,图示画出了两个第二网络的TTI,即TTIB1和TTIB2。当然,这两个部分资源的长度也可以不相同,这里不做限制。基站200通过第一网络指示终端300接收第二网络中TTIB1和TTB2上的下行数据,此时在第一资源上发送的下行控制信息即为下行授权信息。
如图5(a)所示,基站200在RA1上发送调度TTIB1的下行授权信息,在RA2上发送调度TTIB2的下行授权信息,然后基站200通过第一网络将对应TTIB1的下行授权信息和对应TTIB2的下行授权信息发送给终端300。
或者,如图5(b)所示,基站在RA1上发送调度TTIB2的下行授权信息,基站200通过第一网络将对应TTIB2的下行授权信息发送给终端300。这里在时域上,只要保证下行授权信息在所调度的第二网络的TTI之前或者相同时刻发送。当然,基站200可以在RA1上发送调度TTIB2的下行授权信息,还在RA1上发送调度TTIB1的下行授权信息,然后基站200通过第一网络将调度TTIB1的下行授权信息和调度TTIB2的下行授权信息发送给终端300。
或者,如图5(c)所示,保持第一网络的TTI为第二网络的TTI的两倍的对应关系不变的基础上,在时域上扩展到显示4个连续第二网络的TTI,即TTIB1,TTIB2,TTIB3,以及TTIB4。此时,基站200在RA2上发送调度TTIB3的下行授权信息,当然基站200还可以在RA2上发送调度TTIB4的下行授权信息,即下行授权信息可以在时域上与所调度的第二网络的TTI相差一个或者多个第二网络的TTI,总之只要保证下行授权信息在所调度的第二网络的TTI之前或者相同时刻发送。
在图5的场景其它条件保持不变的情况下,若第一网络中用于发送第二网络控制信息的资源被映射到第一网络的PDCCH中,资源调度的方式可以如图6所示。图6中,PDCCH中可以有两个第一资源。这里分别称为RA3和RA4。RA3上发送调度TTIB1的下行授权信息,以及RA4上发送调度TTIB2的下行授权信息。对于第一网络中的PDSCH仍然可以用于传输第一网络的数据信息。
需要说明的是,第一网络的调度资源时间粒度和第二网络的调度资源时间粒度可以为非整数倍的对应关系,或者,第一网络的调度资源时间粒度也可以小于第二网络的调度资源时间粒度,这都不影响本发明的实现。
另外,基站200在第一网络中的第一资源除了用于向终端300发送第二网络的下行控制信息之外,还能够用于基站200向终端300发送第一网络的下行控制信息,此步骤的执行顺序没有严格的规定,在本发明实现的过程当中都可以被执行。
这样基站200能够通过所述第一资源向终端300发送第一网络和第二网络中的下行控制信息,提高了资源的利用率。
或者,所述第一资源还能够用于基站200向能够接收第一网络服务的其它终端发送下行控制信息,这样做同样可以提高资源的利用率。
需要说明的是,本发明实施例中,当第一网络中的一个资源调度时间粒度中包含多个所述第一资源时,多个所述第一资源在时域上可以是连续的,也可以是不连续的。
另外,上述图5和图6所描述的实施例,频域位置相同、时域位置不同的第一资源组成了第一资源集合。类似的,时域位置相同、频域位置不同的第一资源也能够组成第一资源集合,也能够实现本发明的目的,这里不做限制。
可选的,基站200的收发单元220用于在所述第一资源上向所述终端发送所述第二网络的下行控制信息;
其中,所述第一资源上所发送的所述下行控制信息用于调度所述第二网络中第一调度资源时间粒度的资源,且所述第一网络的调度资源时间粒度的长度和所述第二网络的调度资源时间粒度的长度不同。
终端300的收发单元310用于接收基站在所述第一资源上向所述终端发送的第二网络的下行控制信息。
本发明实施例提供的技术方案,基站确定第一网中的资源,并在该资源上发送第二网络中的下行控制信息,实现两个资源调度时间粒度不同的网络之间的跨网络调度,很好的解决了第二网络出现通信超负荷、可靠性低等问题时控制信息传输不能的问题,保证第二网络的控制信息能够准确地传输至用户设备。
为了使得终端300能够获知第一资源集合在第一网络中的具体位置,以便终端300及时到该位置上接收第二网络的下行控制信息,基站200在所述第一资源上向所述终端发送所述第二网络的下行控制信息之前,还可以包括如下步骤:
基站200向终端300发送配置信息,所述配置信息用于向终端300指示所述第一资源集合的位置。
可选的,所述配置信息包括所述资源的时域位置指示信息和所述资源的频域位置指示信息中的至少一种。
其中,所述资源的时域位置指示信息具体可以是基站200在第一网络中的调度资源时间粒度中用于传输第二网络的控制信息的符号数目和位置;所述资源的频域位置指示信息具体可以是基站200在第一网络中的调度资源时间粒度中用于传输第二网络的控制信息的子载波数目和位置。如图7所示,为第一网络下的一个调度资源时间粒度,该调度资源时间粒度可以从时域角度或者频域角度进行描述。图中灰色的部分可以是用于传输第二网络的控制信息的第一资源集合,用上述资源的时域位置信息、资源的频域位置信息或者资源的时域位置信息和资源的频域位置信息能够完整地指示所述资源的位置。
当然,时域位置指示信息或者频域位置指示信息具体的可以通过
比特图形式向终端300指示哪些符号或者哪些子载波组成了第一资源集合。比如,该比特图的比特位为“1”则表示该比特位对应的符号,或者载波属于第一资源集合,等等。
对于该配置信息的发送方式,具体的,当基站200控制第一网络和第二网络时,基站200可以通过第一网络向终端300发送所述资源的配置信息,基站200也可以通过第二网络向终端300发送所述资源的配置信息;当基站200只能控制第一网络时,基站200可以通过第一网络向终端300发送所述资源的配置信息,基站200也可以与控制第二网络的基站(例如,图1(b)中的第二基站)取得联系,将所述资源的配置信息传递给控制第二网络的基站,再由控制第二网络的基站发送给终端300。
进一步地,基站200通过第一网络或者第二网络把所述配置信息发送给终端300,发送的方式可以为通过控制信道,广播信令或者无线资源控制(radio resource control,RRC)信令向所述终端300发送。
具体的实现方式可以如下:
1)通过控制信道
终端300在接入第一网络或者第二网络时,被分配到一个无线网络临时标识符(radio network temporary identifier,RNTI)。
基站200通过第一网络或者第二网络的控制信道通知终端300所述配置信息,所述配置信息可以承载在下行控制信息(downlink control information,DCI)中。
终端300使用被分配的RNTI解调所述DCI,从而获得所述配置信息。
2)通过广播信令
基站200可以通过第一网络或者第二网络的广播信令,将所述资
源的配置信息发送给终端300。该广播信令可以周期性地发送,以便及时更新所述资源的配置信息。
3)通过RRC信令
基站200可以通过第一网络或者第二网络的RRC信令,将所述资源的配置信息发送给终端300。
可选的,基站200的收发单元220用于向终端300发送所述配置信息。
可选的,终端300的收发单元310用于接收基站200发送的所述配置信息。
终端300接收基站200发送的配置信息,实质上是终端300确定第一网络中的第一资源位置的一种实现方式。
基站200向终端发送所述配置信息是一种可选的方法步骤,因此,如果此步骤并未执行,终端300还能够通过预先的协议配置等方式,确定第一网络中第一资源的位置。
可选的,当S402中的下行控制信息中为下行授权信息时,
在所述终端接收所述基站在所述第一资源上向所述终端发送的第二网络的下行控制信息之后,所述方法还可以包括:
终端300根据所述下行授权信息指示的所述第二网络的下行数据的位置,接收在所述下行授权信息所调度的所述第二网络的第一调度资源时间粒度上的所述第二网络的下行数据。
可选的,当S402中的下行控制信息中为上行授权信息时,
在所述终端接收所述基站在所述第一资源上向所述终端发送的第二网络的下行控制信息之后,所述方法还可以包括:
终端300根据所述上行授权信息指示的发送上行数据的位置,发送所述上行数据到所述上行授权信息所调度的所述第二网络的第一
调度资源时间粒度上。
可选的,当S402中的下行控制信息为下行ACK时,在终端300接收基站200在所述第一资源上向终端300发送的第二网络的下行控制信息之后,所述方法还可以包括:
终端300根据所述下行ACK,确认所述下行ACK所调度的所述第二网络的调度资源时间粒度上待应答的上行数据被正确接收;
可选的,当S402中的下行控制信息为下行NACK时,在终端300接收基站200在所述第一资源上向终端300发送的第二网络的下行控制信息之后,所述方法还可以包括:
终端300根据所述下行NACK,确认所述下行NACK所调度的所述第二网络的调度资源时间粒度上待应答的上行数据未被正确接收。进一步地,终端300可以选择重传所述第二网络的调度资源时间粒度中的数据,或者,当重传次数已经达到预设的最大发送次数时,终端300决定取消重传所述第二网络的调度资源时间粒度中的数据数据。
可选的,终端300的收发单元320用于接收在所述下行授权信息所调度的所述第二网络的调度资源时间粒度上的所述第二网络的下行数据。
可选的,终端300的收发单元320用于发送所述上行数据到所述上行授权信息所调度的所述第二网络的第一调度资源时间粒度上。

可选的,终端300的处理单元320用于根据所述下行NACK,确认所述下行NACK所调度的所述第二网络的调度资源时间粒度上待
应答的上行数据未被正确接收。
与基站200在第一网络中在第一资源上向终端300发送第二网络中的下行控制信息相比,终端300也能够通过类似的方式在第一网络中向基站200发送第二网络的上行控制信息。
可选的,本发明实施例提供的技术方案还可以包括以下步骤:
基站200确定第一网络中的第二资源,所述第二资源位于所述第一网络的第二调度资源时间粒度中;
终端300在所述第二资源上向基站200发送所述第二网络的上行控制信息;
其中,所述资源上所发送的所述上行控制信息用于指示所述第二网络中第二调度资源时间粒度上的资源信息。
所述上行控制信息包括:终端身份标识信息(用于让基站200知道该控制信息是否属于哪个终端的),上行ACK信息,上行NACK信息,或者信道状态信息(channel state information,CSI)。
终端300发送上行控制信息时,第二资源的分配方式与第一资源的分配方式相对应,这里不再赘述。
另外,本发明实施例中的第二资源可以与第一资源存在部分重叠或者完全重叠的情况;或者第一网络的第一调度资源时间粒度可能为第一网络中的第二调度资源时间粒度,此处不做限制。
若基站200为仅能够为第一网络提供服务的第一基站,那么基站200在收到所述上行控制信息后,可以将所述上行控制信息再转发给第二网络中的第二基站。
可选的,基站200的处理单元210用于确定第一网络中的第二资源,所述第二资源位于所述第一网络的第二调度资源时间粒度中;
可选的,终端300的收发单元310用于在所述第二资源上向基站
200发送所述第二网络的上行控制信息;
