Description

一种数据传输方法及装置
本申请要求于2013年12月25日提交中国专利局、申请号为201310729346.0、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
本发明涉及通信技术领域，特别涉及一种数据传输方法及装置。
背景技术
物联网就是要实现人与物、物与物的互联互通。可能的应用包括智能电网、智能农业、智能交通、以及环境检测等各个方面。被称为信息产业的第三次浪潮；长期演进(LTE，Long Term Evolution)为支持物联网应用，提供基于LTE的低成本终端，其中降低终端的工作带宽是降低终端成本的方法之一；为了支持更多的窄带机械类型通信(MTC，Machine Type Communication)终端，系统需要划分出多个窄带用于支持MTC终端。由于窄带终端可能无法接收传统的宽带的物理下行控制信道(PDCCH,Physical Downlink Control Channel)上的调度信息，可能需要通过增强物理下行控制信道(ePDCCH,Enhanced-Physical Downlink Control Channel)来接收调度信息。MTC终端选择一个MTC窄带停留，监听ePDCCH上的信息，并根据ePDCCH上的信息接收物理下行共享信道(PDSCH,Physical Downlink Shared Channel)上的信息。
对于ePDCCH而言，根据信道条件不同，传输控制信息所需要的资源是不同，传输控制信息的ePDCCH所需要的增强控制信道元素(eCCE，Enhanced Control Channel Element)的数目是不同的，其中，所需要的资源(即eCCE)的数量被称为聚合等级(aggregation level)。在一定的控制信道资源内，各种聚合等级的ePDCCH混合在一起，如错误！未找到引用源。，图1为聚合等级示意图。图1中以ePDCCH总的资源为64个CCE为例，给出了各个聚合等级的ePDCCH的可能的位置分布。
按照协议规定的规则，极端情况下，如果系统中只存在聚合等级为2和聚合等级为32的ePDCCH，那么，如果某个终端的ePDCCH占据了聚合等级2的0的位 置，那么，聚合等级为32的的ePDCCH就不能再使用0号位置，只能使用0的位置后的1的位置。如果再没有其他的聚合等级为2的ePDCCH，那么，聚合等级2对应的1～15对应的位置，将不会承载任何信息，从而就会造成1～15对应位置的资源浪费。
同时，如果系统中可能存在聚合等级为32的终端，那么，系统就需要划分足够的资源来支持聚合等级32，即使在某个时刻，系统中不存在聚合等级为32的终端。比如，在其它配置相同的情况下，支持聚合等级为2的终端需要4个CCE时，那么，支持聚合等级为32的终端，就需要64个CCE。在某些时刻，比如，系统中不存在需要聚合等级为32的终端时，就会造成资源浪费。
在对现有技术的研究和实践过程中，本发明的发明人发现，现有的实现方式中，聚合等级不同的ePDCCH共享相同的控制信道资源，即：在相同的控制信道资源内，混合有各个聚合等级的ePDCCH，可能造成有些控制资源不能被使用，或者，按照并不存在的高聚合等级分配控制资源，从而导致控制信道资源浪费。

当然，该步骤中，基站也可以划分出几个(比如5个)窄带用来支持MTC通信；或者，规定哪几个集合等级是所述窄带所使用的聚合等级，比如，窄带2支持聚合等级8等，或者，窄带3支持聚合等级1和2等；
步骤202：按照确定的窄带和聚合等级的对应关系，确定所述窄带对应的聚合等级或者所述聚合等级对应的窄带；
该步骤中，按照上述步骤中确定的窄带，根据窄带与聚合等级的对应关系，确定与所述窄带对应的聚合等级；或，按照上述步骤中确定的聚合等级，根据窄带与聚合等级的对应关系，确定与所述聚合等级对应的窄带。
在该步骤中，确定所述窄带与聚合等级的对应关系，可以按照约定的方式来确定，也可以按照非约定的方式了来确定。其中，按照约定的方式，就是基站和UE之间先协商好哪些窄带适用于支持MTC的窄带，支持MTC的窄带所使用的聚合等级等，以及建立二者之间的对应关系；而非约定方式，就是基站将选择好的窄带以及该窄带所使用的聚合等级之间的对应关系告知UE；或者基站将选择好的窄带与聚合等级之间的对应关系告知基站。
其中，非约定方式有两种方式，一种方式是，基站先接收UE按照约定方式确定的窄带与聚合等级对应关系中的窄带和/或聚合等级；然后再确定所述窄带、聚合等级以及窄带与聚合等级的对应关系。另一方式是，基站接收UE发送的窄带和聚合等级的对应关系；根据接收的所述窄带与所述聚合等级的对应关系，确定支持MTC的窄带、聚合等级以及所述窄带和聚合等级的对应关系。
其中，所述窄带与该窄带所使用的聚合等级之间的对应关系，可以是：一个窄带对应一个聚合等级，或者一个窄带对应多个聚合等级，需要说明的是，如果一个窄带对应多个聚合等级，这多个聚合等级的差别不能太大，或者多个聚合等级之差小于某个预定值等，比如一个窄带对应的聚合等级可以为1和2，或者4和8等，而不建议使用2和16等这样的差别较大的聚合等级。
步骤203：在所述窄带上，按照对应的所述聚合等级向用户设备UE发送控制信息，以便于所述UE根据所述控制信息接收数据。
本发明实施例中，由于确定了窄带和聚合等级的对应关系，并在所述窄带上，按照对应的所述聚合等级发送控制信息，从而有效节省了控制资源的浪费。

可选的，在另一实施例中，该实施例在上述实施例的基础的，所述方法还包括：判断是否需要更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系；如果需要，向所述UE发送更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系的更新指示，以便UE根据所述更新指示更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系；并在发送所述更新指示后，更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系。
可选的，在另一实施例中，该实施例在上述实施例的基础的，所述方法还包括：接收所述UE发送的更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系的请求；根据所述请求更新所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系。
可选的，在另一实施例中，该实施例在上述实施例的基础的，所述方法还 包括：判断是否需要更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系；如果需要，向所述UE发送更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系的更新指示，以便UE根据所述更新指示更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系；在发送所述更新指示后，更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系。
可选的，在另一实施例中，该实施例在上述实施例的基础的，所述方法还包括：接收所述UE发送的更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系的请求；根据所述请求更新所述路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系。
可选的，在另一实施例中，该实施例在上述所有实施例的基础的，所述方法还可以包括：判断是否需要更新所述UE的窄带、聚合等级和/或所述窄带与聚合等级的对应关系；如果需要，则向所述UE发送更新所述窄带、聚合等级和/或所述窄带与聚合等级的对应关系的更新指示，以便UE根据所述更新指示更新所述窄带、聚合等级和/或所述窄带与聚合等级的对应关系；在发送所述更新指示后，更新所述UE的窄带、聚合等级和/或所述窄带与聚合等级的对应关系。

可选的，在另一实施例中，该实施例在上述所有实施例的基础的，所述方法还可以包括：将所述窄带和聚合等级中的一个通知给所述UE。
需要说明的是，上述实施例中，确定路径损耗与所述聚合等级的对应关系，与确定所述窄带与聚合等级的对应关系，在时间没有先后顺序，也可以同时进行，本实施例不作限制。
关于所述窄带、聚合等级和/或所述窄带与聚合等级的对应关系的更新，所述窄带、路径损耗和/或所述窄带与路径损耗的对应关系的更新，以及路径损耗、聚合等级和/或所述路径损耗与聚合等级的对应关系的更新，可以由网 络侧发起更新的通知，也可以由UE发起更新的请求，无论那方发起，都需要通知对方，并且在得到显式或者隐式的确认后，才能更新。
本发明实施例中，由于不同的聚合等级对应不同的窄带资源，并确定UE的窄带使用的聚合等级，以及在UE使用的窄带上发送控制信息，从而节省了系统的控制资源。特别是，如果系统中不存在，或者存在较少的需要较高聚合等级的UE，那么，该UE的窄带就不再需要配置支持较高聚合等级的资源，只需要较少资源就可以完成控制信息的发送；减少了需要较高聚合等级的较低聚合等级的控制信道的共存，从而减少了由于较低聚合等级的信道占用较长资源的可能。

如果采用非约定的方式，一种方式是，UE先接收基站按照约定方式确定的窄带与聚合等级对应关系中的窄带和/或聚合等级；然后再确定所述窄带、聚合等级以及窄带与聚合等级的对应关系。另一方式是，UE接收所述基站发送的窄带和聚合等级的对应关系；根据接收的所述窄带与所述聚合等级的对应关系，确定支持MTC的窄带、聚合等级以及所述窄带和聚合等级的对应关系。

为了便于本领域技术人员的理解，下面以具体的应用实例来说明。
还请参阅图8，为本发明实施例提供的一种数据传输方法的应用实例的流程图。在该实施例中，网络侧设备以基站为例，用户设备以MTC终端为例，该实施例指示一种示例，诗句应用中并不限于此。本发明实施例使得支持MTC中的不同窄带采用不同的或者近似的聚合等级，以减少对于控制信道资源的浪费，具体包括：
步骤801：基站确定用于支持MTC通信的窄带与聚合等级的对应关系；
在该实施例中，可以先确定支持机械类型通信MTC的各个窄带，所需要的聚合等级，然后，可以按照约定的方式确定所述窄带与所述聚合等级的对应关系。其具体的确定方式详见上述，在此不再赘述。
其中，用于支持MTC通信的窄带可以有一个或者多个，每个窄带所使用的聚合等级，可以是一个，也可以是多个，但是，每个窄带使用多个聚合等级时，其聚合等级不能差别太大，比如，1和2，4和8等，而不建议是2和16等。
进一步，在该步骤中，基站还可以确定路径损耗(简称路损)与聚合等级的对应关系，比如路损在某个范围时使用某个或者某几个聚合等级等，其一种实例如表1所示。表1表示路损和聚合等级的对应示例，当并不限于此。
表1
路损(dB) 聚合等级
A～B 1,2
C～D 4
E～F 8
G～H 16
I～ 32
在另一实施例中，还可以确定路损与窄带的对应关系，具体与确定路损和聚合等级的对应关系类似，在此不再赘述。
本实施例以确定窄带与聚合等级的对应关系，进一步以确定路损和聚合等级的对应关系为例，但并不限于此。
步骤802：基站向MTC终端发送支持MTC通信的窄带与聚合等级的对应关系；
其中，该步骤802以使得MTC终端获知窄带与聚合等级的对应关系，并便于 选择合适适合自身窄带的聚合等级：
其中，基站下发各个窄带与每个窄带支持的聚合等级的对应关系，其可以通过配置消息下发，当然，也可以通过其他消息下发，本实施例不作限制。
其中，所述窄带与聚合等级的对应关系，一种方式为：
窄带1：聚合等级1，聚合等级2，…
窄带2：聚合等级3，聚合等级4，…
…
或者
聚合等级1：窄带1，窄带2，…
聚合等级2：窄带3，窄带4，…
…
或者
聚合等级1，聚合等级2，…
并约定所发送的聚合等级和窄带的对应关系。
当然，在该步骤中，基站也可以不下发各个窄带以及每个窄带对应的聚合等级信息，而采用约定的方式确定各个窄带所使用的聚合等级，比如，基站划分出5个窄带用于支持MTC通信，约定，窄带1支持聚合等级1、2和4；窄带2支持聚合等级8；窄带3支持聚合等级16；窄带4和5支持聚合等级32等。
进一步，基站还可以将路损与聚合等级的对应关系下发给用户设备。当然，基站和用户设备也可以约定路损与聚合等级的对应关系，而不需要下发，比如，双方约定路损在某个范围时使用某个或者某几个聚合等级等。
步骤803：MTC终端在接收到基站发送所述窄带与聚合等级的对应关系后，确定自身的窄带所使用的聚合等级；
MTC终端根据自身的窄带从所述对应关系中选择对应的聚合等级。
可选的，MTC终端也可以先计算基站到自身的路损；然后MTC终端根据接收到或者约定的路损和聚合等级的对应关系，确定所需要的聚合等级；然后，MTC终端根据接收到的或者约定的聚合等级和窄带的对应关系，确定所工作的窄带。
步骤804：MTC终端将确定的自身使用的聚合等级发送给基站；
该步骤为可选步骤。
在该步骤中，MTC终端可以通过配置响应消息发送给基站，当然，也可以通过其他效果反馈所述MTC终端所需要的聚合等级，以及工作窄带给基站。
步骤805：基站在接收到所述MTC终端所使用的聚合等级后，在所述MTC终端使用的工作窄带上按照发送聚合等级发送控制信息；
当然，在另一实施例中，基站也可以按照约定的方式确定MTC终端所需要的聚合等级，以及确定MTC终端的共作窄带。
进一步，还可以先获取MTC终端的路损信息，其中，基站获取MTC终端的路损信息，可以是基于自身测量，还可以是基于MTC终端的反馈。然后，基站根据路损和聚合等级的对应关系确定MTC终端所需要的聚合等级，然后，根据确定的聚合等级确定MTC终端所工作的窄带，最后，根据需要，在确定的MTC终端的工作窄带上发送控制信息。
步骤806：MTC终端在所述工作窄带上接收基站按照对应的聚合等级发送的控制信息，以及根据接收到的所述控制信息进行数据的接收。
后续步骤807至步骤812为可选步骤，其中，在具体实现过程是，步骤807至步骤809，与步骤810至812为择一实现，也即是说，在具体实现过程中，基站检测是否需要更新，如果需要，则通知MTC终端更新；或者，是MTC终端检测是否需要更新，如果需要，请求基站更新。
步骤807：MTC终端检测是否需要进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新，如果是，执行步骤808；
在该实施例中，只是以是否更新聚合等级、窄带和/或窄带与聚合等级的对应关系为例，但并不限于此。
步骤808：MTC终端通知基站进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新；
步骤809：基站在接收到MTC终端发送的通知时，进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新；
或者；
步骤810：基站检测该MTC终端是否需要进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新，如果是，执行步骤811；
步骤811：基站通知MTC终端进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新；
步骤812：MTC终端在接收到基站发送的通知时，进行聚合等级、窄带和/或窄带与聚合等级的对应关系的更新。
当然，在该实施例中，MTC终端(或基站)在接收到通知后，可以向基站(或MTC终端)发送确认消息，以便于基站或MTC终端进行聚合等级或窄带的更新。
本发明实施例中，如果系统中不存在，或者存在较少的需要较高聚合等级的用户设备，那么，某个窄带就不再需要配置支持较高聚合等级的资源，只需要较少资源就可以完成控制信息的发送；不但减少了需要较高聚合等级的较低聚合等级的控制信道的共存，还降低由于较低聚合等级的信道占用较长资源的可能。从而实现了在宽带系统中支持窄带MTC UE通信，能够有效对于控制信道资源的浪费。
在本发明实施例中，UE可以为以下任意一种，可以是静态的，也可以是移动的，静止的UE具体可以包括为终端(terminal)、移动台(mobile station)、用户单元(subscriber unit)或站台(station)等，移动的UE具体可以包括蜂窝电话(cellular phone)、个人数字助理(PDA，personal digital assistant)、无线调制解调器(modem)，无线通信设备、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或无线本地环路(WLL，wireless local loop)台等，上述UE可以分布于整个无线网络中。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到本发明 可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明各个实施例或者实施例的某些部分所述的方法。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
