Description

控制信息传输方法及基站与终端 技术领域
本发明涉及移动通信领域，尤其涉及控制信息传输方法及基站与终端。
背景技术
随着移动通信技术的不断发展，使用者对基站与终端之间的数据传输速度要求也越来越高。为提高数据传输速度，缩短传输时间间隔(transmission time interval，简称TTI)，从而加快数据过程中反馈确认应答(acknowledgement，简称ACK)的速度和数据重传的速度，缩短数据传输的端到端延时。
在现有长期演进(long term evolution，简称LTE)***中，基站在向终端发送数据时，固定使用每一个子帧的前N个正交频分复用(orthogonal frequency division multiplexing，简称OFDM)符号发送控制信息。终端将一个子帧所包含的所有符号收齐后，对子帧进行解调译码操作，然后根据解调译码的结果确定ACK的内容，所述ACK的内容可以重传该控制信息或是传输下一个控制信息。在ACK的内容确定后，终端在一个子帧中向基站反馈所述ACK。基站在接收到包含所述ACK的子帧后，根据ACK反馈的内容，在下一个子帧中重传该控制信息或输下一个控制信息。
由于控制信息的传输及ACK的传输都各需要一个子帧完成，并且基站及终端对子帧的解析也需要一定的时间，因此基站在发送完一个控制信息之后，需要间隔多个子帧之后才能确定是要重新传输该控制信息或是传输下一个控制信息，两次控制信息传输之间的时间间隔较长。二两次控制信息传输之间的时间间隔较长，则会导致数据传输过程中的端到端延时较大。

参见图1，为本申请控制信息传输方法一个实施例的流程示意图。该实施例所示的方法可以由基站执行。
步骤101，从预设的资源块集中抽取无线资源。
基站在发送控制信息之前，可以首先根据预定抽取规则，从资源块集中抽取在第一时间段中用于发送控制信息的无线资源。其中，所述资源块集中包含的资源块可以是物理资源块也可以是虚拟资源块，所述控制信息可以是指用于控制下行用户数据传输的信息。例如，所述资源块集可以为下行传输带宽对应的多个物理资源块；或者也可以为多个虚拟资源块的集合，其中每个虚拟资源块分别对应一个物理资源块。
所述控制信息可以仅与一个用终端相对应，用于控制该终端的用户数据信息的传输；或者，所述控制信息也可以包括多个子信息，每一个子信息与一个终端相对应，用于控制一个终端的用户数据的传输。
根据实际需求的不同，从资源块集中抽取无线资源时所采用抽取规则也可以有多种。
由于基站可用于发送数据的下行传输带宽由至少一个物理资源块构成，因此在确 定所述无线资源时，基站可以将下行传输带宽所述对应的物理资源块作为一个资源块集，首先从下行传输带宽中抽取出至少一个物理资源块；然后根据所述物理资源块确定所述无线资源。其中，所述基站在抽取所述物理资源块时所用的抽取规则、在确定所述无线资源时所采用的确定规则以及每一个物理资源块所述包含的时域资源数量及频域资源数量都可以由协议预先规定，也都可以由网络侧设备下发。
根据抽取规则的不同，基站可以采用不同的抽取方式抽取可用资源。
可选的，基站可以从所述下行传输带宽对应的多个物理资源块的两端各抽取出一组可用资源。其中，每一组可用资源包含至少一个物理资源块。
如图2所示，当下行传输带宽包括编号为0至N-1的N个物理资源块时，基站可以从下行传输带宽的两端各抽取出M个物理资源块作为一组可用资源。即，发送的可以抽取编号为0至M-1的物理资源块，以及编号为N-M至N-1的物理资源块。其中，其中，N及M均为正整数，N≥M≥2，N的取值由基站的下行传输带宽决定，M的取值可以由协议预先规定，也可以由网络侧设备下发，通常情况下，M的取值可以小于或等于N的取值的一半。
可选的，当所述下行传输带宽包含可用于发送所述控制信息的至少一个可用子频带时，从至少部分所述可用子频带中各抽取一组可用资源。其中，每一组可用资源包含至少一个物理资源块。
如图3所示，当下行传输带宽包括编号为0至X-1的X个可用子频带(subband)，其中，X为正整数，且X≥1，并且每个可用子频带包含N个物理资源块时，基站可以从部分所述可用子频带中各抽取出M个物理资源块作为一组可用资源，或者也可以从每一个所述可用子频带中抽取出M个物理资源块作为一组可用资源。其中，M≤N，所述M的取值可以由协议预先规定，也可以由网络侧设备下发。其中，所述可用子频带可以是所述下行传输带宽的全部子频带，也可以仅为所述下行传输带宽的部分子频带。
基站从可用子频带中抽取物理资源块时，可以将任意一个物理资源块做为起始位置，并抽取M个编号连续的物理资源块，其中，作为起始位置的物理资源块的编号和M的取值可以由协议预先规定，也可以由网络侧设备下发。
在此需要说明的是，当基站从某个可用子频带抽取出可用资源之后，可以使用该可用子频带中的其他资源以及与该可用子频带相邻的若干个子频带所包含的资源可 以用于发送数据信息。进一步，当从某个可用子频带抽取出可用资源用于发送某个终端的控制信息时，该可用子频带中的其他资源以及与该可用子频带相邻的若干个子频带所包含的资源可以用于发送该用户的数据信息。
在抽取出可用资源之后，基站可以在所述可用资源的基础上按照预定的确定规则确定所述无线资源。
基站可以直接将所述物理资源块作为所述无线资源，也可以级联所述物理资源块从而得到所述无线资源。
可选的，基站可以按频率高低顺序或频率倒序依次级联每一组可用资源所包含的物理资源块，从而得到所述无线资源。如图4所示，当所述可用资源被从下行传输带宽两端抽取出时，基站可以按照频率顺序顺次级联编号为0至M-1的RB以及编号为N-M至N-1的RB。如图5所示，当所述可用资源被从子频带中抽取出时，基站同样可以按照频率顺序顺次级联编号为00至0M-1的RB、编号为10至1M-1的RB、以及编号为20M至2M-1的RB。
可选的，基站可以依次从每一组可用资源中抽取物理资源块依次进行级联，得到所述无线资源。如图6所示，当所述可用资源被从下行传输带宽两端抽取出时，基站可以依次级联编号为0、N-M、1、……N-2、M-1、N-1的物理资源块。如图7所示，当所述可用资源被从子频带中抽取出时，基站也可以依次级联编号为00、10、20、……、0M-1、1M-1、2M-1的物理资源块。
当所述可用资源被从下行传输带宽两端抽取出时，基站可以交替从每一组可用资源中抽取一个物理资源块进行级联，得到所述无线资源，其中，在抽取物理资源块时，在一组可用资源中按照频率降序抽取，在另一组可用资源中按照频率升序抽取。如图8所示，当所述可用资源被从下行传输带宽两端抽取出时，基站可以从一组可用资源中按照频率顺序抽取物理资源块，而从另一个组可用资源中降序抽取物理资源块，然后依次级联抽取出的各个物理资源块，从而依次级联编号为0、N-1、1、N-2、……M-1、N-M的物理资源块。
所述下行传输带宽可以是指由虚拟资源块组成的逻辑上的下行传输带宽，该下行传输带宽中的虚拟资源块可以分为分布式虚拟资源块和集中式虚拟资源块，本申请实施例中所说的子频带也可以是从分布式虚拟资源块中获取的子频带，或者是从集中式虚拟资源块中获取的子频带。
在确定所述无线资源时，基站也可以首先抽取预定数量的虚拟资源块；根据资源块集中的虚拟资源块与资源块集中的物理资源块之间的映射关系，确定所述预定数量的虚拟资源块中每一个所述虚拟资源块对应的物理资源块。基站可以直接将所述预定数量的虚拟资源块所对应的物理资源块作为所述无线资源，也可以按照虚拟资源块的次序级联所述预定数量的虚拟资源块中各个所述虚拟资源块所对应的物理资源块得到所述无线资源。
可选的，在确定虚拟资源块时，基站可以从预定位置开始，按虚拟资源块编号顺序或倒序抽取M个虚拟资源块。其中，所述预定位置可以是其中任一个虚拟资源块，1≤M≤N，其中N是分布式虚拟资源块的个数。其中，所述预定位置可以为一个也可以为多个，当所述预定为多个时，基站可以从每一个预定位置开始抽取M个虚拟资源块。所述预定位置及M的取值可以均由协议确定或均由网络侧设备下发，也可以其中一个由网络侧设备下发，另一个由协议确定。例如，基站可以抽取编号为0至编号为M的分布式虚拟资源块；或者，也可以抽取编号为N-1至编号为N-M的分布式虚拟资源块；或者，也可以抽取编号K到编号K+M-1的分布式虚拟资源块；其中，K为正整数，且0≤K<N，1≤M≤N-K，分布式虚拟资源块的个数为N-1。其中，M的取值及K的取值都可以由网络侧设备下发。
可选的，当所述虚拟资源块分别对应于多个交织单元时，基站可以从每一个交织单元中取出至少一个虚拟资源块。在从交织单元抽取虚拟资源块时，可以从每一个交织单元的预定位置开始按虚拟资源块编号顺序或倒序抽取M个虚拟资源块。例如，在从交织单元中抽取虚拟资源块时，基站可以从交织单元的预定位置开始，按虚拟资源块编号顺序或倒序抽取M个虚拟资源块。同样的，1≤M≤N，其中N是交织单元所包含的分布式虚拟资源块的个数。所述预定位置及M的取值由可以均协议确定或均由网络侧设备下发，也可以其中一个由网络侧设备下发，另一个由协议确定。
在此需要说明的是，基站可以仅确定预定数量的集中式虚拟资源块，也可以仅确定预定数量的分布式虚拟资源块，或者也同时确定预定数量的集中式虚拟资源块和预定数量的分布式虚拟资源块。在虚拟资源块被抽取出来之后，基站可以首先确定每一个所述虚拟资源块对应的物理资源块；按照虚拟资源块的次序级联各个所述虚拟资源块所对应的物理资源块。
例如，当抽取出的虚拟资源块为虚拟资源块0至虚拟资源块3，并且虚拟资源块0至虚拟资源块3分别对应物理资源块10、物理资源块7、物理资源块4及物理资源 块1时，可以依次级联物理资源块10、物理资源块7、物理资源块4及物理资源块1，从而得到所述无线资源。
步骤102，使用所述无线资源在所述第一时间段发送所述控制信息。
当所述控制信息仅与一个用终端相对应时，基站可以直接在所述第一时间段使用所述无线资源发送所述控制信息。
当所述控制信息包含多个子信息时，所述基站可以在所述第一时间段采用无交织方式发送所述控制信息，也可以在所述第一时间段采用带交织方式发送所述控制信息。
在采用无交织方式发送所述控制信息时，如果所述控制信息包含一个或多个子信息，将所述无线资源划分为预定数量的子资源，其中每一个所述子资源由从所述无线资源所包含的物理资源块中所抽取的资源元素组所组成，其中，所述预定数量大于或等于所述多个子信息的数量；在所述第一时间段，分别使用所述预定数量的子资源中的一个子资源发送所述多个子信息中的一个子信息。
由于物理资源块所能传输的数据量与子信息所包含的数据量可能不相等，因此在采用无交织方式发送所述控制信息时，基站也可以首先将无线资源划分为预定数量的子资源；然后在所述第一时间段中使用每一个所述子资源发送一个子信息。其中，每一个所述子资源由从所述无线资源所包含的物理资源块中所抽取的资源元素组(resource element group，简称REG)所述组成。每一个子资源所包含REG的数量可以根据需要确定，并且，每一个子资源所包含的REG可以属于同一个物理资源块，也可以分属于不同的物理资源块。其中，所述子资源可以包含从所述无线资源的每一个物理资源块中抽取出REG，也可以包括从所述无线资源的部分物理资源块中抽取出的REG。
例如图9所示，当所述无线资源包括子资源0及子资源1等子资源时，子资源0可以包括从物理资源块0中抽取出REG00、从物理资源块1中抽取出REG10以及从物理资源块2中抽取出REG20等；子资源1可以包括从物理资源块0中抽取出REG01、从物理资源块1中抽取出REG11以及从物理资源块2中抽取出REG21等。
又如图10所示，当所述无线资源包括子资源0、子资源1及子资源2等子资源时，子资源0可以包括从物理资源块00中抽取出的REG000以及从物理资源块10中抽取出的REG100等；子资源1可以包括从物理资源块00中抽取出的REG001以 及从物理资源块10中抽取出的REG101等；子资源2可以包括从物理资源块00中抽取出的REG002以及从物理资源块10中抽取出的REG102等。
在采用带交织方式发送所述控制信息时，基站可以根据控制信息生成带交织的星座点符号流；然后在所述第一时间段，将所述带交织的星座点符号流映射到所述无线资源上进行发送。
基站在根据控制信息生成交织后的星座点符号流时，可以首先生成信息序列；然后对所述信息序列进行加扰与调制得到星座点符号流；再对所述星座点符号流进行交织得到带交织的星座点符号流。其中，当所述控制信息包含多个子信息时，所述信息序列可以由所述子信息级联而成。为使所述信息序列与所述无线资源相对应，当所述控制信息的数据量能够占满所述无线资源时，可以将由各个子信息级联生成的级联序列作为所述信息序列；当所述控制信息的数据量不能占满所述无线资源时，可以在所述级联序列末尾添加预定数量的无值(nil)元素，从而得到所述信息序列。
例如，基站可以将多个子信息的比特块流级联起来得到级联序列，然后在级联序列末尾添加预定数量的nil元素从而得到信息序列b(n)，其中n＝0,1,K,Mtot-1；然后对所述对信息序列b(n)依次进行加扰和调制，得到星座点符号流d(m)，其中，
Figure PCTCN2016073546-appb-000001
Mmod的取值可以由对信息序列b(n)进行调制时所采用的调制方式决定，当采用正交相移键控(quadrature phase shift keyin，QPSK)方式对所述信息序列进行调制时，Mmod的值可以为2，当采用16种符号的正交幅度调制(16quadrature amplitude modulation，16QAM)方式对所述信息序列进行调制时，Mmod的值可以为4，当采用64种符号的正交幅度调制(64quadrature amplitude modulation，64QAM)方式对所述信息序列进行调制时，Mmod的值可以为6；在所述星座点符号流d(m)生成之后，基站可以对所述星座点符号流d(m)进行交织得到带交织的星座点符号流d′(m)。
由于抽取所述无线资源的方式有多种，因此在使用所述无线资源发送所述控制信息之前，基站还可以预先生成并向终端发送指示信息，所述指示信息用于指示所述无线资源的分布位置。从而使基站在接收到所述指示信息后，可以根据所述指示信息确定所述无线资源的分布位置，然后通过所述无线资源接收基站发送的控制信息。
根据所述无线资源的分布位置发生变化的时间粒度不同，发送的可以采用不同的方式指示所述分布位置。基站可以在每一个TTI的第一时间段，使用预定资源发送所述指示信息；或者，基站也可以在控制信道中以公共下行控制信息(downlink control  information，DCI)的形式发送所述指示信息；或者，基站也可以通过高层信令发送所述指示信息。所述指示信息可以用于指示所述无线资源在下行传输带宽中的分布位置。
根据基站从预设的资源块集中抽取无线资源具体方式的不同，所述指示信息的具体内容也可以各不相同。当基站采用图2所示的方式抽取物理资源块时，所述指示信息可以用于指示M的取值。当基站采用图3所示的方式抽取物理资源块时，所述指示信息可以用于指示M的取值，也可以用于指示X的取值，或者也可以用于同时指示M及X的取值。当所述DCI用于指示M的取值，时所述X的取值可以由协议预先规定，也可以由基站通过其他方式指示；当所述DCI用于指示X的取值时，所述X的取值可以由协议预先规定，也可以由基站通过其他方式指示。
当所述无线资源由预定数量的虚拟资源块所对应的物理资源块组成时，所述指示信息可以用于指示作为预定位置的虚拟资源块的编号以及M的取值。其中，当所述虚拟资源块分别对应于多个交织单元时，所述指示信息还可用于指示从哪一个交织单元中取出虚拟资源块。
除此之外，所述指示信息还可以用于指示级联所述可用资源时所采用的级联方式，或者也可以用于指示级联所述虚拟资源块所对应的物理资源块时所采用的级联方式。
采用本实施例，基站可以在任意符号中发送控制信息，从而可以大大缩短数据传输的端到端时延。
在一个TTI中，基站除可以在所述第一时间段之后的第二时间段发送用户数据信息之外，也可以在所述第一时间段发送用户数据信息。在所述第一时间段发送用户数据信息时，可以采用所述下行传输带宽中除用于发送所述控制信息的无线资源之外的其他无线资源发送用户数据信息。
例如，基站可以根据所述控制信息确定用于发送所述用户数据信息的第一发送资源；并使用所述第一发送资源中可用于发送第一控制信息且未被第一控制信息所占用的无线资源发送所述用户数据信息，不使用所述第一发送资源中可用于发送所述第二控制信息所占用的无线资源发送所述用户信息。其中，第一发送资源是指用于发送下行用户数据信息的无线资源，第一控制信息是指用于调度下行用户数据信息的控制信息，第二控制信息是指用于调度上行用户数据信息的控制信息。
当所述下行传输带宽被划分为若干子频带时，如果基站使用某个子频带中的物理资源块发送控制信息，可以使用该子频带中的其他物理资源块或者与该子频带相邻的子频带所包含的物理资源块发送用户数据信息。
除使用所述无线资源发送所述控制信息之外，基站也可以使用所述无线资源发送用户数据信息。例如，当发送所述控制信息占用的所述物理资源块属于第一子频带时，使用所述第一子频带传输所述所述控制信息对应的用户数据信息；或者，使用所述第一子频带及所述第一子频带相邻的子频带传输所述控制信息对应的用户数据信息。
具体来说，当所述控制信息包括上行调度控制信息及下行调度控制信息时，所述无线资源可以包括两个部分，一部分是可用于发送上行调度控制信息的无线资源，另一部分是可用于发送下行调度控制信息的无线资源。当下行调度控制信息数据量较小，未能占满可用于发送下行调度控制信息的无线资源时，基站可以使用所述无线资源中可用于发送下行调度控制信息且未被下行调度控制信息所占用的无线资源发送用户数据信息。在此需要说明是，为避免出现冲突，即便是可用于发送上行调度控制信息的无线资源未被占满，基站通常也不能使用可用于发送上行调度控制信息的无线资源发送用户数据信息。
参见图11，为本申请控制信息传输方法另一个实施例的流程示意图。该实施例所述的方法，可以由于终端执行。
步骤1101，接收指示信息，所述指示信息用于指示无线资源的分布位置；
终端可以根据预定规则，接收指示信息，所述指示信息用于指示无线资源的分布位置。所述指示信息的下发方式和具体内容可以参见前述实施例，在此就不再赘述。
步骤1102，根据所述指示信息的指示，从预设的资源块集中确定目标无线资源；
终端可以根据预定抽取规则，从资源块集中抽取所述目标无线资源。其中，所述预定抽取规则可以预先保存在终端上，或者，也可以由基站通过指示信息发送给终端，或者也可部分保存在所述终端上，而部分由所述基站通过指示信息发送给终端。
可选的，所述终端可以接收指示信息，所述指示信息用于指示目标无线资源的分布位置；根据所述指示信息的指示，从预设的资源块集中确定目标无线资源。
根据所述指示信息所指示的内容不同，终端可以采用不同的抽取规则确定所述目标无线资源，
可选的，终端可以按照所述指示信息所指示的位置从下行传输带宽中抽取出指定 数量的物理资源块；并按照所述指示信息所指示的级联方式级联所述物理资源块得到所述目标无线资源。其中，所述位置及所述指定数量可以预先设定，或由所述指示信息所指示。所述指示信息可以仅用于指示所述指定数量，而所述位置可以由终端根据所述保存在终端上的预定规则确定；或者，所述指示信息也可以仅用于指示所述位置，而所述指定数量则可以由终端根据保存在所述终端上的预设规则确定；或者，所述指示信息可以同时用于指示所述指定数量及所述位置。
可选的，终端也可以按照所述指示信息所指示位置，从所述资源块集所包含的多个虚拟资源块中抽取预定数量的虚拟资源块；确定所述预定数量的虚拟资源块所对应的物理资源作为所述目标无线资源。其中，虚拟资源块位置及虚拟资源块的数量也可以预先设定，或由所述指示信息所指示。
从下行传输带宽中抽取出指定数量的物理资源块的具体方式以及级联方式级联所述物理资源块得到所述目标无线资源的具体方式可以参见前述实施例，例如图3至如10所述对应的具体方式，在此就不再赘述。同样的，抽取预定数量的虚拟资源块的具体方式以及根据所述虚拟资源块所对应的物理资源确定所述目标无线资源的具体方式可以也可以参见前述实施例，在此也不再赘述。
步骤1103，在第一时间段内，通过所述目标无线资源接收控制信息。
在所述目标无线资源确定之后，终端可以在第一时间段内，通过所述目标无线资源接收控制信息。
当所述控制信息仅与所述终端对应时，终端可以接收所述控制信息的全部内容。当所述控制信息包括至少一个子信息时，且仅有若干子信息与终端相对应，而其他子信息与其他终端相对应时，所述终端可以通过所述目标无线资源接收所述终端自身的子信息。
在通过所述目标无线资源接收控制信息时，终端可以先确定所述目标无线资源中的公共搜索空间，通过对所述公共搜索空间进行盲检接收终端的子信息。其中，公共搜索空间从该所述目标无线资源的最小索引资源开始，也可以从目标无线资源的最大索引资源开始，公共搜索空间的长度可以为X个物理资源块。其中，所述X的取值可以由协议预先规定或者由高层信令下发，通常情况下，1≤X≤K，X及K均为正整数，其中K为所述目标无线资源所包含的物理资源块的数量。
在通过所述目标无线资源接收控制信息时，终端也可以先确定所述目标无线资源 中的终端专有搜索空间，通过对所述终端专有搜索空间进行盲检接收终端的子信息。其中，与终端对应专有搜索空间为所述目标无线资源中从与所述终端相对应的起始资源块开始的连续Y个资源块。所述起始资源块可以为所述目标无线资源的第a个资源块，其中，a的取值可以由终端根据终端的UE id得到；其中，所述Y的取值为正整数，并且可以由协议预先规定或者由高层信令下发，通常情况下，1≤Y≤K，其中K为所述目标无线资源所包含的物理资源块的数量。
由于基站可以在所述第一时间段发送用户数据信息。因此终端在所述第一时间段除接收控制信息之外，还可以接收所述控制信息调度的用户数据信息。由于在第一时间段内，基站除使用所述目标无线资源发送控制信息之外，还可能会使用所述目标无线资源发送数据信息，因此所述第一时间段内以及在所述第二时间段内，所述终端还可以接收所述控制信息调度的用户数据信息。
通常情况下，当基站使用某个子频带中的物理资源块发送控制信息时，可以使用该子频带中的其他物理资源块发送用户数据信息，或者使用与该子频带相邻的子频带所包含的物理资源块发送用户数据信息，或者也可能同时使用该子频带中的其他物理资源块及与该子频带相邻的子频带所包含的物理资源块发送用户数据信息。因此，终端还可以在所述控制信息使用的无线资源所属子频带上接收用户数据信息；或者在所述控制信息使用的无线资源所属子频带及相邻子频带上接收用户数据信息。
由于基站还可以使用所述无线资源中可用于发送下行调度控制信息且未被下行调度控制信息所占用的无线资源发送用户数据信息。因此，当所述控制信息包括上行调度控制信息及下行调度控制信息时，所述终端还可以根据所述控制信息确定用于发送所述用户数据信息的第一发送资源，即，使用所述第一发送资源中可用于发送下行调度控制信息且未被下行调度控制信息所占用的无线资源接收所述用户数据信息，但不使用所述第一发送资源中可用于发送所述上行调度控制信息所占用的无线资源接收所述用户信息。
采用本实施例，终端可以接收基站在任意符号中发送控制信息，从而可以大大缩短数据传输的端到端时延。
