Description

一种数据传输方法及装置
本申请要求在2015年8月13日提交中国专利局、申请号为201510497838.0、发明名称为“一种数据传输方法及装置”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
本申请涉及无线通信技术领域，尤其涉及一种数据传输方法及装置。
背景技术
随着物联网的兴起，在长期演进(LTE，Long Term Evolution)系统中支持机器类通信(MTC，Machine Type Communication)越来越受到重视。一台MTC设备(MTC终端)可能具有多种机器与机器(M2M，Machine to Machine)通信特性之中的部分特性，如低移动性、传输数据量小、对通信时延不敏感、要求极低功耗等特征。其中，为了降低MTC终端的成本，新定义一种用户设备类型，其上行和下行均只支持1.4MHz射频带宽。
在现有网络中，在有些场景下工作的用户设备，比如工作于地下室、商场或者建筑角落的用户设备，由于无线信号被严重遮挡，信号受到很大的衰减，无法与网络进行通信，而针对这些场景下进行网络的深度覆盖会大大增加网络的建网成本。实现覆盖增强，一种较为可行的方法是对现有信道采用重复传输或类似技术，以获得一定程度的覆盖增益。
MTC的数据传输是通过下行控制信道调度的。上行数据承载在上行共享信道中传输，下行数据承载在下行共享信道中传输。下行数据传输中包括寻呼(paging)、随机接入响应(Random Access Response，RAR)以及msg4信息的传输，其中msg4信息是随机接入过程中基站发送给用户设备的下行竞争解决信息。根据调度的业务内容不同，下行控制信道可以在公共搜索空间中传输，也可在用户设备(User Equipment，UE，即终端)专属的搜索空间中传输。
寻呼消息在根据预定规则确定的可以传输寻呼消息的子帧中传输。在同一个寻呼子帧中，可以传输多个用户设备的寻呼消息，这些寻呼消息承载在下行共享信道中，通过在公共搜索空间中传输的寻呼-无线网络临时标识(Paging-Radio Network Temporary Identity，P-RNTI)加扰的下行控制信道调度。
RAR消息的传输即随机接入过程中的msg2传输，承载在下行共享信道中，通过在公共搜索空间中传输的随机接入-无线网络临时标识(Random Access-Radio Network Temporary，RA-RNTI)加扰的下行控制信道调度。对应相同RA-RNTI的用户设备的RAR消息可以同时承载在同一个下行共享信道中传输。
考虑到覆盖增强模式下，数据传输需要占满一个窄带(1.4MHz)的6个物理资源块 (Physical Resource Block，PRB)进行传输，以缩短重复传输次数。即一个窄带在同一个子帧中只能传输一个下行共享信道。如果在下行控制信道接收窗口中同时发送了多个下行控制信道，这些下行控制信道所调度的数据传输可能存在资源冲突。对于寻呼消息，当前子帧中需要进行寻呼的多个用户设备都只能通过同一个P-RNTI调度，但这些用户设备的覆盖增强等级(level)可能不同，因此重复次数不同，不同重复次数的下行共享信道需要独立发送，例如，时分多路复用(Time-Division Multiplexing，TDM)传输模式下按照先后顺序发送不同覆盖增强等级的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，而频分多路复用(Frequency Division Multiplexing，FDM)传输模式下则在不同窄带发送。对于RAR消息，如果不同覆盖增强等级的用户设备所使用的RA-RNTI相同，同样存在上述类似问题。
发明内容

所述用户设备根据所述下行控制信道中承载的N个物理共享信道的调度信息，在所述N个物理共享信道上进行数据传输。
本申请实施例提供的基站，包括：

发送模块，用于发送所述下行控制信道，所述下行控制信道中承载所述N个物理共享信道的调度信息。
本申请实施例提供的用户设备，包括：
接收模块，用于接收下行控制信道，所述下行控制信道中承载所述N个物理共享信道的调度信息，所述N个物理共享信道具有不同的覆盖增强等级和/或重复传输次数，N为大于1的整数；
数据传输模块，用于根据所述下行控制信道中承载的N个物理共享信道的调度信息，在所述N个物理共享信道上进行数据传输。
本申请的上述实施例中，由于一个下行控制信道中承载有具有不同的覆盖增强等级和/或重复传输次数的物理共享信道的调度信息，从而实现具有不同重复次数的物理共享信道独立发送，避免了下行控制信道所调度的数据传输发生资源冲突。

其中，每个调度信息域包含多个指示域，每个指示域用于承载一种类型的调度信息。这里的指示域是指一个信息单元，该信息单元可承载一种调度信息，比如可承载资源分配信息或者承载调度编码信息等调度信息。根据该信息单元所承载的内容，可通过对该信息单元的命名将不同指示域进行区分，比如，承载资源分配信息的信息单元称为资源分配指示域，承载调度编码信息的信息单元称为调度编码指示域，以此类推。以下实施例中的指示域的含义与此相同，不再赘述。
以一个物理共享信道的调度信息域中包含M个指示域为例，采用级联方式一的一种实现方式是：N个调度信息域顺序级联，且每个调度信息域中包含的M个指示域顺序级联。
图2示例性地示出了一种采用上述级联方式一的DCI。其中，N＝3，即下行控制信道 调度的物理共享信道的数量为3个，且这3个物理共享信道具有不同的覆盖增强等级，分别表示为：level1、level2、level3。在一种示例中，如图2所示，一个DCI中包含3个顺序级联的调度信息域，level1的调度信息域中包含覆盖增强等级为level1的物理共享信道的调度信息域中的M个顺序级联的指示域，level2的调度信息域中包含覆盖增强等级为level2的物理共享信道的调度信息域中的M个顺序级联的指示域，level3的调度信息域中包含覆盖增强等级为level3的物理共享信道的调度信息域中的M个顺序级联的指示域。
级联方式二
下行控制信道使用的DCI中包含N个调度信息域，每个调度信息域承载所述N个物理共享信道中的一个信道的调度信息中所包含的指示信息，所述N个调度信息域交织级联。
其中，每个调度信息域包含第一至第M指示域，每个指示域用于承载一种类型的指示信息，M为大于1的整数。采用级联方式二的一种实现方式是：DCI中包含M个顺序级联的信息域，每个信息域包含N个物理共享信道的调度信息域中的相同类型的指示信息，且每个信息域中包含的N个指示信息顺序级联。
图3示例性地示出了一种采用上述级联方式二的DCI。其中，N＝3，即下行控制信道调度的物理共享信道的数量为3个，且这3个物理共享信道具有不同的覆盖增强等级，分别表示为：level1、level2、level3。在一种示例中，如图3所示，一个DCI中包含M个顺序级联的信息域，每个信息域中包含3个指示域，其中，第1信息域中包含3个物理共享信道的调度信息域中的资源分配指示域，第2指示域中包含3个物理共享信道的调度信息域中的调度编码指示域，以此类推。可以看出，这N个物理共享信道的调度信息域交织级联，例如，按照调度信息域的功能顺序级联，在同一功能的调度信息域中不同覆盖增强等级和/或重复传输次数的物理共享信道的调度信息域顺序级联。第1信息域至第三信息域中的level1的指示域构成了覆盖增强等级为level1的物理共享信道的调度信息域，以此类推。
级联方式三
下行控制信道使用的DCI中包含1个共享信息域以及N个专属调度信息域，所述共享信息域用于承载所述N个物理共享信道的调度信息中的共享内容部分，每个专属调度信息域用于承载所述N个物理共享信道中的一个信道的调度信息中的专属内容部分，所述N个专属调度信息域顺序级联。
如前所述，物理共享信道的调度信息中可包含多种信息，其中有部分调度信息可以是这N个物理共享信道所共享的，可承载在共享信息域中，其他部分调度信息是每个物理共享信道专属的，承载在各自物理共享信道的专属信息域中。
一个DCI中的指示域通常包括资源分配指示域、调制编码指示域、HARQ进程号指示域、新数据指示域、冗余版本指示域等等。考虑到一个DCI调度的多个PDSCH都是独立传输的，所以当每个PDSCH都需要对应独立的HARQ进程号指示域、新数据指示域时， 即至少这两个域是不能共享的，而从节省信令开销的角度，冗余版本指示域可以共享。在一些其他的例子中，可以根据需要对某种或某些调度信息进行共享。例如，如果不同覆盖增强等级的调制编码差异不大，则调制编码指示域可以共享；如果多个PDSCH采用TDM方式发送，从节省信令开销的角度，资源分配指示域可以共享；如果需要更为灵活的调度不同PDSCH的频域资源位置，那么资源分配指示域也可以不共享；如果多个PDSCH采用FDM方式发送，由于频域位置肯定不同，此时资源分配指示域不能共享，或者可能资源分配指示域中再进一步分为窄带指示域以及窄带内的PRB指示域，那么窄带指示域可以不共享，而窄带内的PRB指示域可以共享。
图4示例性地示出了一种采用上述级联方式三的DCI。其中，N＝3，即下行控制信道调度的物理共享信道的数量为3个，且这3个物理共享信道具有不同的覆盖增强等级，分别表示为：level1、level2、level3。在一种示例中，如图4所示，一个DCI中包括1个共享信息域以及3个物理共享信道的专属调度信息域，共享信息域中承载3个物理共享信道的共享调度信息，每个专属调度信息域包含一个物理共享信道的调度信息域中的K个指示域，K小于或等于M。共享信息域以及level1的专属调度信息域构成了覆盖增强等级为level1的物理共享信道的调度信息域，以此类推。
级联方式四
下行控制信道使用的DCI中包含1个共享信息域以及N个专属调度信息域，所述共享信息域用于承载所述N个物理共享信道的调度信息中的共享内容部分，每个专属调度信息域用于承载所述N个物理共享信道中的一个信道的调度信息中的专属内容部分，所述N个专属调度信息域交织级联。
其中，所述N个专属调度信息域交织级联是指：所述DCI中包含K个顺序级联的信息域，每个信息域包含N个物理共享信道的调度信息中的专属内容部分中的相同类型的指示信息，且每个信息域中包含的N个指示信息顺序级联。
如前所述，物理共享信道的调度信息中可包含多种信息，其中有部分调度信息可以是这N个物理共享信道所共享的，可承载在共享信息域中，其他部分调度信息是每个物理共享信道专属的，一个专属信息域中可承载N个物理共享信道的调度信息中的同一种指示域。
图5示例性地示出了一种采用上述级联方式四的DCI。其中，N＝3，即下行控制信道调度的物理共享信道的数量为3个，且这3个物理共享信道具有不同的覆盖增强等级，分别表示为：level1、level2、level3。在一种示例中，如图5所示，一个DCI中包括1个共享信息域以及K个信息域，共享信息域中承载3个物理共享信道的共享调度信息，每个信息域包含3个指示域，分别承载这3个物理共享信道的调度信息域中承载相同类型调度信息的指示域，比如，第1信息域包含3个指示域，分别为第一至第三物理共享信道的调度信息域中的资源分配指示域，第2信息域包含3个指示域，分别为第一至第三物理共享信 道的调度信息域中的调度编码指示域，以此类推。共享信息域以及第1至第K信息域中的level1的指示域构成了覆盖增强等级为level1的物理共享信道的调度信息域，以此类推。
上述各种级联方式中，当一个物理共享信道的调度信息中的全部或者部分指示域被置为特定值时，表示该下行控制信道中不包含具有该物理共享信道的调度信息，该特定值是不同于调度信息的参数值的一个数值。比如，如果下行控制信道中不包括覆盖增强等级为level1的物理共享信道的调度信息，则可将该覆盖增强等级为level1的物理共享信道的调度信息中的一个指示域，例如资源分配指示域设置为一个特定的值，比如一个全0或者全1的比特序列，当终端检测到该DCI中对应覆盖增强等级为level1的物理共享信道的调度信息的资源分配指示域为上述约定的特定值时，判断该DCI中并没有实际传输覆盖增强等级为level1的物理共享信道的调度信息。
可选地，下行控制信道所调度的物理共享信道可被重复传输，相应地，下行控制信道中还可承载有所述N个物理共享信道的重复传输次数。
可选地，步骤102中，基站可重复发送所述下行控制信道。优选地，基站可按照所述下行控制信道所调度的目标用户设备中的最大重复传输次数进行重复发送。即，如果该下行控制信道所调度的目标用户设备中包括了3个覆盖增强等级，覆盖增强等级1对应的下行控制信道重复传输次数为N1，覆盖增强等级2对应的下行控制信道重复传输次数为N2，覆盖增强等级3对应的下行控制信道重复传输次数为N3，则该下行控制信道的重复传输次数确定为max(N1，N2，N3)，其中max为取最大值的操作。
进一步地，图1所示的流程中，在步骤102之后，还包括以下步骤(此步骤未在图中示出)：步骤103：基站传输所述N个物理共享信道。具体地，在下行方向上，基站可向下行控制信道调度的目标用户设备发送N个物理下行共享信道，在上行方向上，基站可接收下行控制信道调度的目标用户设备发送的N个物理上行共享信道。
步骤103中，所述N个物理共享信道可采用TDM方式重复传输，即，基站按照设定的先后顺序传输所述N个物理共享信道。
其中，重复传输完成一个物理共享信道后开始传输下一个物理共享信道，比如，具有第一覆盖增强等级和/或重复传输次数的物理共享信道先进行重复传输，完成重复传输之后，具有第二覆盖增强等级和/或重复传输次数的物理共享信道进行重复传输，以此类推。
其中，在本申请的一些实施例中，所述设定的先后顺序可包括以下几种中的一种：
-按照覆盖增强等级和/或重复传输次数由低到高的顺序；
-按照覆盖增强等级和/或重复传输次数由高到低的顺序；
-按照预定的对不同的覆盖增强等级和/或重复传输次数交织后的顺序。
当然，除上述给出的几种传输顺序以外，也不排除其他的传输顺序。
可选地，N个物理共享信道的起始传输子帧的定时关系可以是：所述N个物理共享信 道的起始传输子帧，为n+k子帧后的第一个可用子帧；其中，n表示所述下行控制信道传输所在的下行控制信道传输时间段内的最后一个子帧的编号，k为大于或等于1的整数。
可选地，按照所述设定的先后顺序，第i+1个物理共享信道的传输起始子帧为第i个物理共享信道的最后一个重复传输子帧之后的第一个可用子帧；其中，按照所述设定的先后顺序，第i+1个物理共享信道的传输顺序排列在第i个物理共享信道之后，1≤i≤N。
步骤103中，优选地，所述N个物理共享信道的重复传输次数是预先定义的；或者，所述N个物理共享信道的重复传输次数，是根据覆盖增强等级下的传输块大小(Transport Block Size，TBS)与重复传输次数的对应关系获得的。
步骤103中，所述N个物理共享信道也可采用FDM方式重复传输，即，基站在不同的频域资源上传输所述N个物理下行共享信道。进一步地，所述下行控制信道所使用的DCI中包括独立的用于指示所述N个物理共享信道的每个信道的频域资源的调度信息。
其中，频域资源可以仅包括窄带信息和PRB信息中的一种，即N个物理共享信道可以在同一个窄带中的不同PRB传输，或者在不同窄带中的在该窄带中的相对位置相同的PRB传输，或者同时包括窄带信息和PRB信息，即N个物理共享信道可以在同一个窄带中的不同PRB传输，或者在不同窄带中的在该窄带中的相对位置相同的PRB传输，或者在不同窄带中的在该窄带中的相对位置不同的PRB传输。
可选地，在本申请的上述各实施例中，下行控制信道所使用的DCI总是按照系统中存在的不同的覆盖增强等级和/或不同的重复传输次数的总个数进行设计的，即如果系统中支持了3个覆盖增强等级和/或3个重复传输次数，则上述DCI中总是包括了3个覆盖增强等级和/或3个重复传输次数的物理共享信道的调度信息域；在实际传输时，如果当前需要传输的物理共享信道的覆盖增强等级和/或重复传输次数的个数小于系统指示的最大个数，则将不需要被调度的覆盖增强等级和/或重复传输次数的物理共享信道的调度信息中的全部或者部分指示域置为特定值，表示该下行控制信道中不包含具有该覆盖增强等级和/或重复传输次数的物理共享信道的调度信息。
通过以上描述可以看出，本申请上述实施例中，由于一个下行控制信道中承载有具有不同的覆盖增强等级和/或重复传输次数的物理共享信道的调度信息，从而实现具有不同重复次数的物理共享信道独立发送，避免了下行控制信道所调度的数据传输发生资源冲突。
参见图6，为本申请实施例提供的用户设备侧实现的数据传输流程。如图所示，该流程可包括以下步骤：
步骤601：用户设备接收下行控制信道，所述下行控制信道中承载N个物理共享信道的调度信息，所述N个物理共享信道具有不同的覆盖增强等级和/或重复传输次数，N为大于1的整数。

其中，在上行方向上，用户设备可根据下行控制信道所调度的PUSCH发送上行数据；和/或，在下行方向上，用户设备可根据下行控制信道所调度的PDSCH接收下行数据。
上述流程中，下行控制信道调度所述N个具有不同的覆盖增强等级和/或重复传输次数的物理共享信道的方式，如下所述。
所述N个物理共享信道的调度信息可承载在DCI中。所述N个物理共享信道的调度信息中可包含多种信息，举例来说，可包含以下种类的信息中的一种或组合：资源分配信息、调度编码信息、HARQ信息、新数据信息、冗余版本信息、传输格式信息、功率控制信息等等。

其中，每个调度信息域包含第一至第M指示域，每个指示域用于承载一种类型的指示信息，M为大于1的整数。所述N个调度信息域交织级联是指：所述DCI中包含M个顺序级联的信息域，每个信息域包含N个物理共享信道的调度信息中的相同类型的指示信息，且每个信息域中包含的N个指示信息顺序级联；所述N个专属调度信息域交织级联是指：所述DCI中包含K个顺序级联的信息域，每个信息域包含N个物理共享信道的调度信息中的专属内容部分中的相同类型的指示信息，且每个信息域中包含的N个指示信息顺序级联。具体级联方式以及例子与前述实施例相同，在此不再赘述。
下行控制信道通常被重复传输。本申请实施例中可选地，下行控制信道按照所调度的目标用户设备中的最大重复传输次数进行重复发送，以保证用户设备能够接收和解调。
进一步地，下行控制信道中还可承载有所述N个物理共享信道的重复传输次数。这样，用户设备可根据下行控制信道中承载的物理共享信道的重复传输次数，在被调度的物理共享信道上进行数据传输。其中，所述N个物理共享信道的重复传输次数是预先定义的；或者，所述N个物理共享信道的重复传输次数，是根据覆盖增强等级下的TBS与重复传输 次数的对应关系获得的。
所述N个物理共享信道可采用TDM方式传输，这种情况下，所述N个物理共享信道按照设定的先后顺序传输，其中，重复传输完成一个物理共享信道后开始传输下一个物理共享信道。
优选地，所述设定的先后顺序可包括：按照覆盖增强等级和/或重复传输次数由低到高的顺序；或者，按照覆盖增强等级和/或重复传输次数由高到低的顺序；或者，按照预定的对不同的覆盖增强等级和/或重复传输次数交织后的顺序。
进一步地，在所述N个物理共享信道可采用TDM方式传输的情况下，所述N个物理共享信道的传输子帧的定时关系可以是：所述N个物理共享信道的起始传输子帧，为n+k子帧后的第一个可用子帧，其中，n表示所述下行控制信道传输所在的下行控制信道传输时间段内的最后一个子帧的编号，k为大于或等于1的整数。进一步地，按照所述设定的先后顺序，第i+1个物理共享信道的传输起始子帧为第i个物理共享信道的最后一个重复传输子帧之后的第一个可用子帧；其中，按照所述设定的先后顺序，第i+1个物理共享信道的传输顺序排列在第i个物理共享信道之后，1≤i≤N。
所述N个物理共享信道可采用FDM方式传输，这种情况下，所述N个物理下行共享信道在不同的频域资源上传输。其中，所述下行控制信道所使用的DCI中可包括独立的用于指示所述N个物理共享信道的每个信道的频域资源的调度信息。
可选地，在本申请的上述各实施例中，下行控制信道所使用的DCI总是按照系统中存在的不同的覆盖增强等级和/或不同的重复传输次数的总个数进行设计的，即如果系统中支持了3个覆盖增强等级和/或3个重复传输次数，则上述DCI中总是包括了3个覆盖增强等级和/或3个重复传输次数的物理共享信道的调度信息域；在实际传输时，如果当前需要传输的物理共享信道的覆盖增强等级和/或重复传输次数的个数小于系统指示的最大个数，则将不需要被调度的覆盖增强等级和/或重复传输次数的物理共享信道的调度信息中的全部或者部分指示域置为特定值，表示该下行控制信道中不包含具有该覆盖增强等级和/或重复传输次数的物理共享信道的调度信息。
通过以上描述可以看出，本申请上述实施例中，由于一个下行控制信道中承载有具有不同的覆盖增强等级和/或重复传输次数的物理共享信道的调度信息，从而实现具有不同重复次数的物理共享信道独立发送，避免了下行控制信道所调度的数据传输发生资源冲突。
为了更清楚地理解本申请实施例，下面结合具体场景对本申请的上述实施例的具体实现过程进行描述。
如图7所示，对于RAR消息，承载该消息的PDSCH采用FDM方式传输，在获取承载RAR消息的PDSCH的调度信息时，用户设备在公共搜索空间中按照上述PDSCH采用FDM方式传输时所设计的DCI格式检测RA-RNTI加扰的下行控制信道，该DCI中不同覆 盖增强等级和/或重复传输次数的调度信息中分别包含用于指示该覆盖增强等级和/或重复传输次数的PDSCH传输所在的窄带信息的指示域，并对其调度的承载不同覆盖增强等级和/或重复传输次数的RAR消息的PDSCH按照图示的不同窄带频分的方式进行重复传输；其中，下行控制信道与不同覆盖增强等级和/或重复传输次数的PDSCH之间的调度定时关系为n+k，n为下行控制信道传输时间段中的最后一个子帧(也可以是该下行控制信道重复传输的最后一个子帧，但并不一定是该下行控制信道重复传输的最后一个子帧)，k为预定义的时延值。
