本发明涉及通信领域,并且更具体地,涉及传输控制信令的方法和装置。
背景技术
大规模多输入多输出(Massive MIMO)技术是未来5G移动通信系统的关键技术之一。它是通过大规模地使用廉价的低功耗低精度的有源天线器件去服务有限个数的用户。尽管每一个天线单元的发射功率都不高,但是通过大规模天线的协同工作,有效地利用空间特性,将辐射能量聚焦在一小部分空间区域,即用较窄的辐射波束对准用户,从而带来吞吐量和能量使用效率的大幅提升。
现有4G长期演进(Long Term Evolution,简称为“LTE”)系统/LTE-高级(Advanced)系统的全宽带控制信道设计方案,造成了极大地资源浪费。因此,有必要提供一种新的传输控制信令的方法。

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,显然,所描述的实施例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付出创造性劳动的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。
应理解,本发明实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,简称为“GSM”)系统、码分多址(Code Division Multiple Access,简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称为“WCDMA”)系统、长期演进(Long Term Evolution,简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex,简称为“FDD”)系统、LTE时分双工(Time Division Duplex,简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System,简称为“UMTS”)、以及未来的5G通信系统等。
应理解,在本发明实施例中,终端设备也可以称为用户设备(User Equipment,简称为“UE”)用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(Wireless Local Area Networks,简称为“WLAN”)中的站点(Station,简称为“ST”),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称为“SIP”) 电话、无线本地环路(Wireless Local Loop,简称为“WLL”)站、个人数字处理(Personal Digital Assistant,简称为“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备。
网络设备可以是网络设备等用于与移动设备通信的设备,网络设备可以是WLAN中的接入点(Access Point,简称为“AP”),码分多址(Code Division Multiple Access,简称为“GSM”或“CDMA”)中的基站(Base Transceiver Station,简称为“BTS”),也可以是WCDMA中的基站(NodeB,简称为“NB”),还可以是长期演进(Long Term Evolution,简称为“LTE”)中的演进型基站(Evolutional Node B,简称为“eNB”或“eNodeB”),或者中继站或接入点,或者车载设备、可穿戴设备以及未来5G网络中的网络设备。
需要说明的是,本发明实施例的方法可以应用于Massive MIMO系统,也可应用到有限天线系统。本发明基于现有物理广播信道(Physical Broadcast Channel,简称为“PBCH”)的设计方案不变的场景,但也可应用于其他物理信道改变的场景。
图1是根据本发明实施例的传输控制信令的方法的示意性流程图,该方法可以由网络设备执行,如图1所示,该方法100包括:
S110,将控制信令承载在通用控制信道上,该通用控制信道在频域上占用系统带宽内的M个子载波,M为大于或等于1且小于该系统带宽内的子载波总数的正整数,该控制信令中包括能够用来指示两个或两个以上终端设备操作动作的公共控制信令;
S120,通过该通用控制信道发送该控制信令。
具体而言,网络设备可以将控制信令承载在频域上占用系统带宽的部分带宽的通用控制信道上,并在该通用控制信道上向终端设备发送控制信令,并且该控制信令中可以包括能够用来指示两个或两个以上终端设备操作的公共控制信令。
因此,本发明实施例的传输控制信令的方法,将能够用来指示两个或两个以上终端设备操作动作的公共控制信令承载在占用系统带宽内的部分带宽的控制信道上,由此能够提高传输资源的使用效率。
需要说明的是,系统带宽可以理解为现有通信标准中的信道带宽(Channel Bandwith),例如,演进的UMTS陆面无线接入(Evolved Universal  Terrestrial Radio Access,E-UTRA)系统可以支持的系统带宽可以有1.4MHz、3MHz、5MHz、10MHz、15MHz、20MHz等。
应理解,在本发明实施例中,通用控制信道可以承载能够用来指示两个或两个以上终端设备操作动作(Behavior)的公共控制信令和只指示一个终端设备操作动作的用户专有控制信令,可以将S110中的通用控制信道称为公共控制信道。但本发明的保护范围并不限于此名称。
可选地,在S110中,该通用控制信道可以为现有LTE系统中的物理下行控制信道(Physical Downlink Control Channel,简称为“PDCCH”),还可以为能够用于承载公共控制信令其他控制信道,本发明对此不作限定。
可选地,在S110中,该公共控制信令可以通过携带可以被两个或两个以上终端设备识别的标识的方式来指示两个或两个以上终端设备的操作动作,该公共控制信令还可以通过加扰的方式指示两个或两个以上终端设备的操作动作。例如,该公共控制信令为通过用可以被两个或两个以上终端设备使用的标识来加扰的控制信令。其中,两个或两个以上终端设备也可以理解为至少两个终端设备。
举例来说,该公共控制控制信令可以为现有通信标准中用系统信息-无线网络临时标识(System Information-Radio Network Temporary Indentifier,简称为“SI-RNTI”)加扰的DCI format 1A,或,用寻呼-无线网络临时标识P-RNTI加扰的DCI format 1C,或,用随机接入响应-无线网络临时标识RA-RNTI加扰的物理下行共享信道(Physical Downlink Shared Channel,简称为“PDSCH”)信令,但本发明并不限于此。
可选地,在S110中,该可以被两个或两个以上终端设备使用的标识包括如下标识中的一种或多种:系统信息-无线网络临时标识SI-RNTI、随机接入响应-无线网络临时标识RA-RNTI、寻呼-无线网络临时标识P-RNTI。
具体来说,现有4G LTE/LTE-Advanced系统中的系统信息块(System Information Block,简称为“SIB”)携带广播系统信息,该SIB上携带的广播系统信息是小区系统信息的主体,不同的系统信息组成不同的SIBs,这些SIBs在PDSCH上进行传输,与该信道上传输的单播数据频分复用,被称为PDSCH上的动态广播信道(Dynamic Broadcast Channel,简称为“DBCH”);SIBs在一个子帧中的PDSCH上出现的位置和传输格式,由通过SI-RNTI来加扰的控制信令指示。
现有4G LTE/LTE-Advanced系统中的通知类信息包括随机接入响应(RAR)信息和寻呼(Paging)信息。它们在PDSCH上传输的位置和传输格式分别由通过RA-RNTI和P-RNTI来加扰的控制信令指示。
进一步地,该控制信令还包括只指示一个终端设备操作动作的用户专有控制信令,该用户专有控制信令包括下列信息中的至少一种:资源分配信息、调制和编码方案信息、混合自动重传请求HARQ信息、预编码信息、上行数据信道或上行控制信道的功率控制信息、参考信号指示信息、信道信息测量的触发指示信息、探测参考信号的触发指示信息和载波分量的指示信息。
在本发明实施例中,可选地,S120具体为:
通过该通用控制信道上的至少一个控制信令单元CCE发送该控制信令。
举例来说,如图2所示,浅颜色填充部分表示通用控制信道占用的时频资源,深颜色填充的部分表示控制信令单元(Control Channel Elements,简称为“CCE”),通用控制信道可以包括多个CCE,在传输控制信令时,可以将待传输的控制信令映射到多个CCE上,进行控制信令的发送,例如在图2中,可以将一个公共控制信令映射到3个CCE上进行发送。
并且,进一步地,网络设备可以根据控制信令的传输条件、小区尺寸以及控制信令的传输范围等参数确定传输控制信令时所需要的CCE的数量和发射功率。
在本发明实施例中,可选地,该通用控制信道包括公共搜索空间和/或用户专有搜索空间。其中,公共搜索区间(Common Search Space)可以是现有标准中所有UE都需要监听的区间,通常用来发送寻呼消息,RAR消息、系统消息,以及部分UE公用的上行功率控制消息等。公共搜索区间占据从0开始到最大数目为16的CCE,公共搜索区间内的PDCCH只有4CCE和8CCE两种类型的大小,UE需要在公共搜索区间内,从0开始,按CCE粒度为8进行搜索2次,按CCE粒度为4搜索4次,至多需要进行6次PDCCH的搜索。用户专有搜索空间(UE-Specific Search)可以是现有标准中只需特定UE监听的区间,用户专有搜索空间的起始点取决于UE的标识ID(C-RNTI),子帧号,以及PDCCH的类型,随着子帧的不同,用户专有搜索空间也有所不同。并且公共搜索空间承载的公共控制信令中有扰码序列身份(Scrambling Identity,简称为“SCID”)的标识比特以支持多个不同的扰码序列,网络设备(如eNB)可以将这多个扰码序列分配给不同的用户,在同一 资源复用多个用户;用户专有搜索空间和/或公共搜索空间承载的用户专有控制信令中有SCID的标识比特以支持一个扰码序列,这一个SCID只能分配给一个用户,用户也只能释用自己的SCID加扰的用户专有控制信令。
如图3(a)和3(b)所示,浅颜色填充部分表示公共搜索空间,斜线填充的部分为用户专有搜索空间。图3(a)中的一个控制信令可以为公共控制信令或用户专有控制信令,并且Common Search Space能够承载公共控制信令和/或用户专有控制信令,UE-Space Search Space只能够承载用户专有控制信令,例如,在图3(b)中的控制信令为用户专有控制信令。换句话说,公共控制信令承载在公共搜索空间上,用户专有控制信令承载在公共搜索空间和用户专有搜索空间中的至少一种搜索空间上。
在本发明实施例中,可选地,M个子载波是离散分布的。也就是说,M个子载波中的部分子载波可以是连续分布的,而其他子载波离散分布;或者,M个子载波之间均是离散的,如图3(a)或3(b)所示(图中由下往上对应的频率由低变高),通用控制信道在频域上占用3部分带宽,每部分带宽包括至少一个子载波,并且这三部分带宽之间是离散的。优选地,一部分带宽位于系统带宽的高频端,一部分带宽位于系统带宽的中央,一部分带宽位于系统带宽的低频端。由于带宽是离散分布的,所以在传输控制信令时,能够获取频率使用效率和频率分集增益的平衡。
在本发明实施例中,可选地,数据信道和用户专有控制信道中的至少一种信道与该通用控制信道以频分复用的方式占用频域资源,其中,该数据信道为承载数据的信道,该用户专有控制信道为只承载用户专有控制信令的信道。可选地,该数据信道可以为现有技术中的PDSCH,该用户专有控制信道可以为现有技术中的增强的物理下行控制信道(Enhanced Physical Downlink Control Channel,简称为“ePDCCH”),由此可以获取预编码增益、频域调度增益以及干扰协调增益。
在本发明实施例中,可选地,通用控制信道在时域上可以占用一个子帧的全部符号。优选地,该通用控制信道在时域上占用一个子帧中的N个符号,N为小于一个子帧所有符号的总个数的任意正整数,例如,本小区的通用控制信道占用一个子帧中编号分别为12、13和14的符号。其他小区的通用控制信道可以占用除编号为12、13和14的符号之外的其他符号,由此能够避免相邻小区之间控制信令的干扰。
更进一步地,如图4所示,通用控制信道占用的时频资源可以分成多个区域,图4中分成了3个区域,分别为由斜线填充的两个区域和由浅色填充的区域。可以将不同的区域分配给不同的小区或扇区,并由物理控制格式指示信道(如Physical Control Format Indicator Channel,简称为“PCFICH”)指示为一个小区或扇区所分配的时频区域,例如,图4中本小区的通用控制信道可以占用由浅颜色填充的区域,其他两个区域分别预留给邻小区#1和邻小区#2,由此能够实现小区间干扰协调。
在本发明实施例中,可选地,该通用控制信道与数据信道可以采用相同的预编码方式,和/或,波束赋形方式,和/或,功率分配方案。优选地,该通用控制信道与数据信道采用的预编码方式,和/或,波束赋形方式,和/或,功率分配方案不同。
在本发明实施例中,可选地,该通用控制信道可以采用与用户专有控制信道相同的预编码方式,和/或,波束赋形方式,和/或,功率分配方案,优选地,该通用控制信道采用的预编码方案与用户专有控制信道采用的预编码方式,和/或,波束赋形方式,和/或,功率分配方案不同。
具体来说,如图5所示,多个天线单元(Antenna Point,简称为“AP”)向终端设备发送控制信令和数据,其中,编号为#0至#3的天线单元通过宽波束在窄带(通用控制信道或公共控制信道)上发送指示多个终端设备操作动作的公共控制信令,并且为了保证多个终端设备成功接收控制信令,采用广域覆盖的预编码方式,并且所有发射功率全部分配给待发送的控制信令。而编号为#4至#N的天线单元采用窄波束在较宽的频带(用户专有控制信道或数据信道)上发送只指示一个终端设备的操作动作的用户专有控制信令或对应于一个终端设备的数据,可以采用普通的预编码方式,并且可以按照优先将发射功率分配给用户专有控制信令,再将剩余功率分配给数据的功率分配方式进行发送。
在本发明实施例中,可选地,该通用控制信道的发送功率的分配先于该数据信道的发射功率的分配;和/或,该通用控制信道的发射功率的分配先于该用户专有控制信道的发送功率的分配。换句话说,在一个通信系统中只有通用控制信道和数据信道时,该通用控制信道的发射功率的分配先于该数据信道的发射功率的分配;在一个通信系统中只有通用控制信道和用户专有控制信道时,该通用控制信道的发射功率的分配先于用户专有控制信道的发射 功率的分配;在一个通信系统中既有通用控制信道,又同时具有数据信道和用户专有控制信道时,通用控制信道的发射功率的分配先于数据信道的发射功率的分配,且通用控制信道的发射功率的分配先于用户专有控制信道的发射功率的分配。也就是说,网络设备可以将发射功率优先分给该通用控制信道占用的频段以保证控制信令的传输质量,由此能够提高控制信令的接收可靠性。
进一步地,该通用控制信道占用的该M个子载波可以被分成L个子载波集合,该L个子载波集合中每个子载波集合包括至少一个子载波,L小于或等于M,该L个子载波集合采用的预编码方式,和/或,波束赋形方式,和/或功率分配方案可以相同也可以不同。
具体来说,该L个子载波集合可以采用不同的预编码方式,比如,一部分子载波集合可以采用基于空间相关矩阵的预编码方式,而另一部分子载波集合可以采用基于码本的预编码方式。该L个子载波集合可以采用不同的波束赋形方式,比如,一部分子载波集合可以采用单流波束赋形方式,而另一部分子载波可以采用双流波束赋形方式。该L个子载波集合还可以采用不同的功率分配方案,例如,一部分子载波集合只用于传输公共控制信令,所以可以将所有的发射功率都分配给公共控制信令,而另一部分子载波集合既可以可以用于传输公共控制信令又可以传输用户专有控制信令,所以可以按照优先将发射功率分配给公共控制信令,剩余功率分配给用户专有控制信令的方式进行发射功率的分配,但本发明并不限于此。
更进一步地,该L个子载波集合可以均匀分配发射功率,优选的,该L个子载波集合的发射功率的分配优先级不同。具体来说,可以先将发射功率中的部分功率分配给一部分子载波集合,保证这部分子载波集合承载的控制信令能够被成功接收,然后将剩余的发射功率分配给其他的子载波集合。例如,还可以对L个子载波集合进行优先级的排序,在功率分配时按照优先级的高低顺序进行分配,优先保证优先级高的子载波集合上承载的控制信令的接收成功率。
因此,本发明实施例的传输控制信令的方法,将能够用来指示两个或两个以上终端设备操作动作的公共控制信令承载在占用系统带宽内的部分带宽的控制信道上,由此能够提高传输资源的使用效率。
以上结合图1至图5从网络设备侧详细描述了根据本发明实施例的传输 控制信令的方法,下面将结合图6从终端设备侧详细描述根据本发明实施例的传输控制信令的方法,应理解,网络设备侧描述的终端设备与网络设备的交互及相关特性、功能等与终端设备侧的描述相应,为了简洁,适当省略重复的描述。
图6是根据本发明另一实施例的传输控制信令的方法的示意性流程图,该方法可以由终端设备执行。如图6所示,该方法200包括:

具体来说,终端设备通过在频域上占用系统带宽内的部分带宽的通用控制信道接收包括能够用于指示两个或两个以上终端设备操作动作的公共控制信令,之后解调该接收到的控制信令。
因此,本发明实施例的传输控制信令的方法,能够用来指示两个或两个以上终端设备操作动作的公共控制信令承载在占用系统带宽内的部分带宽的控制信道上,由此能够提高传输资源的使用效率。
需要说明的是,系统带宽可以理解为现有通信标准中的信道带宽(Channel Bandwith),例如,演进的UMTS陆面无线接入(Evolved Universal Terrestrial Radio Access,E-UTRA)系统可以支持的系统带宽可以为1.4MHz、3MHz、5MHz、10MHz、15MHz、20MHz等。

在本发明实施例中,可选地,该公共控制信令承载在该公共搜索空间上。
