实施例一、
本实施例提供一种传输方法，可以但不限于应用于窄带系统的下行数据发送，如图1所示，包括：
S110、接入网网元当存在待传输的下行数据时，对全部或部分开销信道的下行空口资源进行打孔；所述开销信道包括以下一种或几种：固有的开销信道、预设的开销信道、调度的开销信道；所述开销信道包括以下任一种或任几种类型的信道：下行广播信道、下行同步信道、下行参考信道、多播信道；
S120、所述接入网网元使用打孔的下行空口资源调度所述待传输的下行数据。
本实施例中，所述下行广播信道包括以下一种或几种：固有的下行广播信道、预设的下行广播信道、调度的下行广播信道；类似地，所述下行同步信道、下行参考信道、多播信道也分别包括固有的、预设的、调度的 相应信道中的一种或几种。所述开销信道包括接入网网元向用户设备发送信令的控制信道，还包括用于用户设备与接入网元进行同步的同步信道、用于检测信道质量的各种信道等。所述同步信道可包括传输主同步信号的主同步信道及传输辅同步信号的辅同步信道。所述参考信道包括发送下行参考信号的下行信道等。在本实施例中，被打孔的开销信道可选为除所述控制信道以外的开销信道，以免影响接入网网元的控制信令的传输。
在本实施例中所述步骤S120传输下行数据，这里的下行数据为用户面数据，例如，各种用户面的下行数据。这样的话，将开销信道对应的部分时频资源打孔出来，用于用户面数据的下行传输，相当于增加了传输用户面数据的时频资源，显然可以更加快速的响应用户设备的下行的用户面数据的请求，提升数据传输效率及用户面数据的传输容量。与此同时，为了避免开销信道的重新配置导致的额外增加配置信令开销的问题，在本实施例中利用打孔的方式，对开销信道进行打孔，不用修改开销信道资源的资源配置，简化了时频资源用途的转化，具有实现简便的特点。在本实施例中，所述被打孔用于用户面的下行数据传输的时频资源，一般是所述开销信道的空闲资源，这样还可以提升开销信道的资源有效利用率。
所述方法在执行所述步骤S110之前还可包括：
检测所述开销信道的资源使用状况；
若所述资源使用状况表明所述开销信道有资源空闲，则对所述开销信道进行打孔。
当然进一步地，所述方法还可包括：
检测当前用户面的下行数据的传输资源的使用状况信息；
若该使用状况信息表明，用户面下行数据的传输资源紧张，例如，使用率大于阈值，则在步骤S110中，在所述所述资源使用状况表明所述开销 信道有资源空闲，且所述用户面的下行数据的传输资源紧张时，对开销信道进行打孔。
在步骤S120中将利用开销信道中被打孔位置的时频资源传输用户面的下行数据。例如，所述开销信道包括N个时频资源，且依次编号从第1到第N个时频资源。若对第M个时频资源进行打孔，则打孔位置等于第M个时频资源，所述第M时频资源即所述步骤S120中用于用户面的下行数据的打孔的下行空口资源。
本实施例中，接入网网元进行打孔前，可以先根据待传输的下行数据所需要的时频资源数量，来确定是否打孔；如果打孔，确定对下行广播信道、下行同步信道、下行参考信道、多播信道中哪些信道的时频资源进行打孔。

接入网网元将打孔后空闲出的时频域资源调度给PDSCH(Physical Downlink Shared Channel，物理下行共享信道)使用，并将对应的下行数据调度信令发送给目标用户设备；所述目标用户设备是指所述待传输的下行数据的接收方。
相应地，目标用户设备可以根据所述下行数据调度信令接收发给自己的PDSCH，从而在打孔位置获得所述待传输的下行数据。
可选地，所述对全部或部分开销信道的下行空口资源进行打孔包括：

实际应用时，进行打孔的下行空口资源还可以设置为用于传输某个或某些SIB的空口资源，比如用于传输除了SIB1和SIB2以外的SIB的空口资源。
可选地，当对下行同步信道进行打孔时，进行打孔的下行空口资源包括：用于传输PSS(Primary Synchronization Signal，主同步信号)，和/或，辅同步信号SSS(Secondary Synchronization Signal，辅同步信号)的空口资源。

本可选方案中，在用户设备收到被打孔的开销信道前，接入网网元将提前告知覆盖区域(可以但不限于为小区内)的用户设备打孔的位置，通过所述相关信息限定打孔的位置，还可以告知打孔的周期。
至于具体何时发送相关信息，可以自行设置；可以是对开销信道打孔后发送所述相关信息，也可以是在使用打孔位置发送待传输的下行数据前发送所述相关信息，还可以是在确定对哪些资源打孔后就发送所述相关信息。总之，所述相关信息是与打孔位置相关的信息，例如，指示所述打孔位置的频域位置、时域位置、资源长度、打孔周期等各种信息。
实际应用中，也可以通过事先约定、默认等方式确定打孔的时域和/ 或频域资源位置，在告知时中只指示“已打孔”；或者，可以通过事先约定、默认等方式确定多个时域和/或频域资源位置，并与索引号一一对应，在告知时只给出索引号即可得知打孔位置；再或者，可以通过事先约定、默认等方式确定时域或频域位置，告知时只告知频域或时域位置即可。

本实施方式中，该标识可以但不限于为1比特，可称为“打孔与否”标识；用户设备在下行数据调度信令中看到此标识，则认为在下行数据调度信令中指配给自己的空口资源中，原本包含的固有、预设或者调度的开销信道的位置都已经被打孔，替换为了数据信道。

实施例六、
本实施例提供一种用户设备，包括实施例五所述的传输装置。
本实施例提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行前述传输方法的至少之一，例如，可执行图1、图3、图7及图8中所示方法的一个或多个。所述计算机存储介质可为非瞬间存储介质。
下面用两个实施示例说明上述实施例。
实施示例1：
以LTE NBIoT接入网为例，图5是未打孔时的空口资源指示图，图6A～C分别是三种打孔的例子中，打孔后的空口资源指示图；
如图5所示，可以看到按照正常的窄带系统的需要，下行BCH (Broadcast Channel，广播信道)、PSS/SSS、MCH(Multicast channel，多播信道)、下行参考信号均需要发送。
如图6A～C所示，在打孔的区域，广播信道、PSS/SSS、MCH、下行参考信号均可以被打掉(即可以对BCH、MCH、下行同步信道、下行参考信道的下行空口资源进行打孔)，开销信道被打掉后空闲出来的空口资源被调度给PDSCH用于发送下行数据。
在图6A中，是对整块的时频区域打孔(包含了多个频段和多个子帧)，在t1到t2和f1到f2这块时频区域101内的广播信道、PSS/SSS、MCH、下行参考信号均被打掉，变成空闲资源。接入网网元可按需利用这块空闲资源来进行下行数据调度。
在图6B中，是以子帧为单位对全频段进行了打孔，将子帧a，b内的所有广播信道、PSS/SSS、MCH、下行参考信号均打掉，变成空闲资源。接入网网元可按需利用这块空闲资源来进行下行数据调度。图6B也可以按照不同的帧单位进行全频段打孔，例如按照系统帧为单位进行打孔，或者按照超帧(一超帧＝1024系统帧)进行打孔；
在图6C中，是做小粒度的打孔，以RE为粒度将下行参考信号打掉，比如打掉RE-1、RE-2、RE-3、RE-4；小粒度的打孔方式也可以应用在对广播信道、PSS/SSS、MCH的打孔上。
图6为本实施示例方案流程图，包括步骤201～205；详细说明见下：
步骤201、接入网网元有下行数据待传输时，接入网网元根据自己的调度算法确定调度该下行数据所需的时频域资源数量；
步骤202、接入网网元根据自身负荷水平，用户数等信息确定是否需要对BCH、PSS/SSS、MCH、下行参考信号中一种或多种所占用的资源位置进行打孔。例如，当负荷水平很轻，或者活跃用户数很少时，空闲的空口 资源较多，此时可以不对开销信道进行打孔；当负荷水平较重，或者活跃用户数较多时，则适合对开销信道进行打孔，以临时获取更多的下行空口资源来进行下行数据调度；
并且，根据负荷水平的不同，接入网网元可决定对哪些开销信道进行打孔，例如可以只对广播信道进行打孔，或者只对广播信道的部分系统消息进行打孔(例如，可以对除了MIB，SIB1和SIB2之外的其他SIB进行打孔)，也可以只对PSS/SSS进行打孔，也可以只对MCH进行打孔，或者对广播信道和PSS/SSS进行打孔，也可以只对下行参考信道进行打孔。
实际应用中，哪种情况下进行打孔、对哪些开销信道进行打孔等实现细节可以自行设计；上述描述只作为一个例子，并不用于对方案进行限定。
步骤203、若确定需要打孔，接入网网元确定打孔的时频域资源位置；
本步骤中，根据步骤202确定：
(1)所要打孔的开销信道种类以及调度该下行数据所需的时频域资源数量，确定需要打孔的时频域资源位置；
(2)确定是采用一次性打孔还是周期性打孔；所述周期性打孔是指按照一个固定的时间间隔重复进行相同时频域资源位置的打孔。
步骤204、接入网网元将打孔后空闲出的时频域资源调度给PDSCH使用，并将对应的下行数据调度信令发送给目标用户设备；目标用户设备根据所述下行数据调度信令接收发给自己的PDSCH；
接入网网元可在下行数据调度信令中携带显式的“开销信道打孔”指示，也可以不携带这种指示。
当不携带“开销信道打孔”指示时，则用户设备通过隐式规则来判断 下行数据调度信令所指配的空口资源中是否包含被打孔的开销信道；即：
当需要接收下行数据信道的用户设备收到的下行数据调度信令中所指配的空口资源包含了全部或部分开销信道的空口资源位置，则所述用户设备默认这些开销信道的空口资源位置均被打孔，替换为了数据信道；其中，开销信道可以包括固有的、预设的或调度的开销信道，包括以下信道类型中的一种或多种：下行广播信道、下行同步信道、下行参考信号、多播信道。
当携带“开销信道打孔”指示时，则用户设备通过该指示来判断下行数据调度信令所指配的空口资源中是否包含被打孔的开销信道；所述指示可以采用以下方式之一：
方式1：1bit的“打孔与否”标识，用户设备在下行数据调度信令中看到此标识则认为在调度信令中指配给自己的空口资源中，原本包含的开销信道的下行空口资源都已经被打孔，替换为了数据信道；
方式2：具体的分别指示出，在下行数据调度信令中指配给用户设备的空口资源中，哪些原本包含的开销信道的下行空口资源被打孔，替换为了数据信道；例如：为下行广播信道、下行同步信道、下行参考信号、多播信道分别设置1个标识，4个标识分别指示所述4种开销信道各自被打孔与否，以及被打孔的时频域资源位置；被调度的用户设备即可通过下行数据调度信令中的上述4个标识获知在指配给自己的空口资源中，哪种开销信道被打孔，以及其被打孔的具体时频域资源位置；用户设备认为这些被打孔的位置均被替换为了数据信道。
步骤205、任何需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备(即：除所述目标用户设备以外，所述接入网网元覆盖范围内的任何用户设备)当在开销信道的空口资源处没有收到相应信号时，在下一个相应的空口资源位置接收相应信号，即，进行如 下操作中的任一项或任几项：
当在下行广播信道的空口资源处没有收到广播消息时，在下行广播信道的下一个空口资源位置接收广播消息；所述下行广播信道包括固有、预设或者调度的下行广播信道；
当在下行同步信道的空口资源处没有收到下行同步信号时，在下行同步信道的下一个空口资源位置接收下行同步信号；所述下行同步信道包括固有、预设或者调度的下行同步信道；
当在下行参考信道的空口资源处没有收到下行参考信号时，在下行参考信道的下一个的空口资源位置接收下行参考信号；所述下行参考信道包括固有、预设或者调度的下行参考信道；
当在多播信道的空口资源处没有收到多播信号时，在多播信道的下一个空口资源位置接收多播信号；所述多播信道包括固有、预设或者调度的多播信道。
所述步骤205还可以包括：需要接收下行数据的用户设备在开销信道的打孔位置接收下行数据。
实施示例2
以LTE NBIoT接入网为例，打孔前后的空口资源示意图如图5及图6A～C所示，可参见实施示例1的描述。
图7为本实施例方案流程图，包括步骤301～306；详细说明见下：
步骤301、接入网网元有下行数据待传输，接入网网元根据自己的调度算法确定调度该下行数据所需的时频域资源数量；
步骤302、接入网网元根据负荷水平，用户数等信息确定是否需要对BCH、PSS/SSS、MCH、下行参考信号中一种或多种所占用的资源位置进行 打孔。例如，当负荷水平很轻，或者活跃用户数很少时，空闲的空口资源较多，此时可以不对开销信道进行打孔；当负荷水平较重，或者活跃用户数较多时，则适合对开销信道进行打孔；
并且，根据负荷水平的不同，接入网网元可决定对哪些开销信道进行打孔，例如可以只对广播信道进行打孔，或者只对广播信道的部分系统消息进行打孔(例如，可以对除了MIB，SIB1和SIB2之外的其他SIB进行打孔)，也可以只对PSS/SSS进行打孔，也可以只对MCH进行打孔，或者对广播信道和PSS/SSS进行打孔。
步骤303、若确定需要打孔，接入网网元确定打孔的时频域资源位置；
本步骤中，根据步骤302确定所要打孔的开销信道种类以及调度该下行数据所需的时频域资源数量，确定需要打孔的时频域资源位置，确定是采用一次性打孔还是周期性打孔；所述周期性打孔是指按照一个固定的时间间隔重复进行相同时频域资源位置的打孔；所述周期性打孔的持续的周期数可以由接入网网元自行确定后告知用户设备，也可以采用当打孔周期数到达后发送一个“打孔已停止”的标识给用户设备；
步骤304、接入网网元将所述被打孔的空口资源的相关信息提前告知覆盖区域的用户设备；
所述相关信息包括：
所占用的时域长度和或具体的时刻、频域长度和或具体的频域位置、或当采用周期性打孔时的周期；
例如：以图6A为例，相关信息可以是整个打孔区域t1～t2,f1～f2；也可以是所述打孔区域中各个开销信道被打孔的具体时频域资源位置；
所述告知方式包括：通过广播消息发送、或通过寻呼消息发送、或通 过PDCCH发送；
所述通过广播消息发送被打孔的空口资源的相关信息，具体包括：
将所述被打孔的空口资源的相关信息立刻更新在广播消息中，可选地，可以不修改用于指示广播消息变更的valueTag指示标志。例如在SIB1或者SIB2，或者其他SIB中进行更新。
如果是需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备在广播消息中收到开销信道被打孔的下行空口资源的位置，跳过这些打孔位置，在下一个相应的空口资源位置相应接收广播信道、或下行同步信号、或下行参考信号、或多播信号；
如果是不需要接收任何开销信道的用户设备则可以略过开销信道打孔的相关信息。
所述通过寻呼消息发送被打孔的空口资源的相关信息，具体可以采取以下两种方式之一：
方式1：新增一个专用的寻呼RNTI，例如叫：PUNCH-P-RNTI，专门用于指示该寻呼消息是用来通知所述被打孔的空口资源的相关信息的用途；
例如：在LTE系统中，寻呼P-RNTI在RNTI列表中为FFFE，RNTI列表中有保留值FFF4-FFFC，可在其中任选一个定义为PUNCH-P-RNTI；
所述PUNCH-P-RNTI用于对调度所述寻呼消息的PDCCH进行加扰；
所述被打孔的空口资源的相关信息放在所述寻呼消息中发送给小区内用户设备；
用户设备当检测到PDCCH被PUNCH-P-RNTI加扰，那么如果是需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备就可以去接收和解调该PDCCH调度的寻呼消息以获取开销信道被打孔的资源位置；并跳过这些打孔位置，在相应开销信道的下一个空口资源位置 接收相应的信号，包括：广播消息、或下行同步信号、或下行参考信号、或多播信号；
如果是不需要接收任何开销信道的用户设备检测到PDCCH被PUNCH-P-RNTI加扰，则可以略过该PDCCH调度的寻呼消息。
方式2：所述被打孔的空口资源的相关信息放在寻呼消息中发送给小区内用户设备；
任何收到该寻呼消息的用户设备都需要接收并解调该寻呼消息，若在寻呼消息中获得所述开销信道打孔的相关信息，那么如果是需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备就可以去接收和解调该PDCCH调度的寻呼消息以获取开销信道被打孔的资源位置；并跳过这些打孔位置，在相应开销信道的下一个空口资源位置接收相应的信号，包括：广播消息、或下行同步信号、或下行参考信号、或多播信号；
如果是不需要接收任何开销信道的用户设备则可以略过该条寻呼消息中的开销信道打孔的相关信息。
可选地，可以在寻呼消息中增加新的标识，该标识专用于指示“本寻呼消息用于指示开销信道打孔的相关信息”；
所述通过PDCCH发送被打孔的空口资源的相关信息，具体可以包括：
在PDCCH中增加新的信息单元以承载所述被打孔的空口资源的相关信息；
可选的，新增一个专用的PUNCH-RNTI，用于对所述PDCCH进行加扰，以指示该PDCCH用来通知所述被打孔的空口资源的相关信息；
用户设备当检测到PDCCH被PUNCH-RNTI加扰，那么如果是需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备 就可以去接收和解调该物理下行控制信道的内容以获取开销信道被打孔的下行空口资源的位置；并跳过这些打孔位置，在下一个相应的空口资源位置相应接收广播消息、或下行同步信号、或下行参考信号、或多播信号；
如果是不需要接收任何开销信道的用户设备检测到物理下行控制信道被PUNCH-RNTI加扰，则可以略过该物理下行控制信道，不进行解调。
步骤305、接入网网元将打孔后空闲出的时频域资源调度给数据信道使用，并将对应的下行数据调度信令发送给目标用户设备；目标用户设备根据所述下行数据调度信令接收发给自己的PDSCH；
接入网网元可在下行数据调度信令中携带显式的“开销信道打孔”指示(即前文所述的打孔指示)，也可以不携带这种指示，采用隐含的方式指示打孔位置。
当不携带“开销信道打孔”指示时，则用户设备通过隐式规则来判断下行数据调度信令所指配的空口资源中是否包含被打孔的开销信道；即：
当需要接收下行数据信道的用户设备收到的下行数据调度信令中所指配的空口资源包含了全部或部分开销信道的空口资源位置，则所述用户设备默认这些开销信道的空口资源位置均被打孔，替换为了数据信道；其中，开销信道可以包括固有的、预设的或调度的开销信道，包括以下信道类型中的一种或多种：下行广播信道、下行同步信道、下行参考信号、多播信道。
当携带“开销信道打孔”指示时，则用户设备通过该指示来判断下行数据调度信令所指配的空口资源中是否包含被打孔的开销信道；所述指示可以采用以下方式之一：
方式1：1bit的“打孔与否”标识，用户设备在下行数据调度信令中看到此标识则认为在下行数据调度信令中指配给自己的空口资源中，原本 包含的开销信道的下行空口资源都已经被打孔，替换为了数据信道；
方式2：具体的分别指示出，在下行数据调度信令中指配给用户设备的空口资源中，哪些原本包含的开销信道的下行空口资源被打孔，替换为了数据信道；例如：为下行广播信道、下行同步信道、下行参考信号、多播信道分别设置1个标识，4个标识分别指示所述4种开销信道各自被打孔与否，以及被打孔的时频域资源位置；被调度的用户设备即可通过下行数据调度信令中的上述4个标识获知在指配给自己的空口资源中，哪种开销信道被打孔，以及其被打孔的具体时频域资源位置；用户设备认为这些被打孔的位置均被替换为了数据信道；
所述步骤305还可以包括：需要接收下行数据的用户设备在开销信道的打孔位置接收下行数据。
步骤306、任何需要接收下行广播信道、或下行同步信道、或下行参考信号、或多播信道的用户设备(即：除所述目标用户设备以外，所述接入网网元覆盖范围内的任何用户设备)当收到接入网网元提前告知的被打孔的空口资源的相关信息时，跳过所述相关信息指示的打孔位置，不在这些打孔位置进行下行开销信道的接收，在所述这些打孔位置之后的下一个相应的空口资源位置接收相应信号；所述相应信号包括以下任一种或任几种：广播消息、下行同步信号、下行参考信号、多播信号。
相应的空口资源位置是指与打孔位置对应的空口资源，比如打孔位置为固有的广播信道，则相应的空口资源为固有的广播信道的空口资源；再比如打孔位置为调度的下行同步信道，则相应的空口资源为调度的下行同步信道的空口资源；以此类推。
本实施示例通过显式的将开销信道被打孔位置提前告知覆盖区域的所有用户设备，虽然比起实施例1增加了接入网网元和用户设备的实施复杂度，但是使得用户设备避免了在被打孔位置去无用的接收开销信道，从而 减少了用户设备的功耗。
上述方传输法的各个步骤均可以由处理器或处理电路实现。所述处理器可包括中央处理器、数字信号处理器、微处理器、应用处理器或可编程阵列等。
本领域的技术人员应该明白，上述的本发明实施例的全部或部分模块、以及全部或部分步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置(如只读存储器、磁盘或光盘等)中由计算装置来执行，或者将它们分别制作成多个集成电路，或者将它们中的多个模块或步骤制作成单个集成电路来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
虽然本发明所揭露的实施方式如上，但所述的内容仅为便于理解本发明而采用的实施方式，并非用以限定本发明。凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
