实施例一
本实施例描述的是使用缺省的HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)重传次数或无HARQ重传的下行数据传输的方法，图3为本实施例所述方法的流程示意图。如图3所示，本实施例所述方法包括以下步骤：
步骤100，有下行业务数据或信令到达基站；
该下行业务数据或信令可以是通过寻呼消息或其它S1接口消息从核心网来到基站的，也可以是从业务服务器或互联网路由器来到基站的，还可以是从相邻接入网网元来到基站的。S1接口是LTE(Long Term Evolution，长 期演进)eNodeB(基站)与EPC(分组核心网)之间的通讯接口。
在该步骤中，基站还可能收到以下至少之一：UE的空口能力信息、UE的寻呼图样信息。
步骤101，基站根据UE的空口能力和寻呼图样发送寻呼消息，其中，寻呼消息包括新分配给UE的用于无线资源调度的标识，例如C-RNTI(Cell Radio Network Temporal Index，小区无线网络临时标识)。
寻呼消息中还可以携带UE的寻呼标识，例如IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)、IMEI(International Mobile Station Equipment Identity，国际移动站设备标识)、或者P-TMSI(Packet Temporary Mobile Subscription Identity，分组临时移动用户识别码)。
UE接收寻呼消息，根据UE的寻呼标识确定是否正在被网络侧寻呼(被网络侧寻呼通常意味着UE需要和网络侧进行通信以便接收下行信令或数据)，UE进一步将接收到的C-RNTI作为自身的标识，以便使用新分配的用于无线资源调度的标识(C-RNTI)来解码PDCCH(Physical Downlink Control Channel，物理下行控制信道)。
步骤102，基站发送无线资源调度信息，所述无线资源调度信息包括：为所述UE分配的下行物理资源信息，例如，PDCCH/DCI(Downlink Control Information，下行控制信息)，其中使用在寻呼消息中携带的分配给UE的用于无线资源调度的标识；例如C-RNTI通过DCI的CRC(Cyclic Redundancy Check，循环冗余校验码)隐含携带；
UE使用上一步获取的用于无线资源调度的标识(C-RNTI)解码PDCCH，解码PDCCH的方法可采用业界周知的方法(可以参见3GPP TS36.211/36.212/36.213协议)，在此不再赘述。
UE接收到无线资源调度信息(例如DCI)后，根据DCI中指示的物理资源指示、MCS(Modulation and Coding Scheme，调制编码方式)等用于接收PDSCH的信息准备接收下行空口数据。
步骤103，基站发送下行空口数据；
UE根据基站分配的下行物理资源信息接收下行空口数据，例如，根据DCI中指示的物理资源指示、MCS等用于接收PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的信息来接收下行空口数据，并进行接收正确或错误判别。在接收正确后将接收到的传输块投递给上层协议(MAC(Medium Access Control，媒体接入控制)/RLC(Radio Link Control，无线链路控制)/PDCP(Packet Data Convergence Protocol，分组数据汇聚协议))进行处理。
步骤104，基站在预定的间隔时间后，重传下行空口数据；预定的间隔时延可以是0，也可以是网络侧和UE都支持的TTI(Transmission Time Interval，发送时间间隔)的整数倍。
步骤105，基站在达到最大重传次数后结束传输，释放前面分配的C-RNTI(意味着C-RNTI只是临时使用)，并可以向业务或信令发起方报告传输结果，其中包括是否成功进行了下行传输的指示。在指示传输失败时，则还携带失败的原因，例如下行资源不足。
在该实施例中，UE是支持快速下行传递的任何类型终端，例如移动互联网终端，比如智能手机，也可以是物联网或车联网终端。
实施例二
本实施例描述的是在基站发送的寻呼消息中配置专用反馈信息，但无需接收到专用反馈直接开始发送数据的方法，图4为本实施例所述方法的流程示意图。如图4所示，本实施例所述方法包括以下步骤：
步骤200，有下行业务数据或信令到达基站。
该下行业务数据或信令可以是通过寻呼消息或其它S1接口消息从核心网来到基站的，也可以是从业务服务器或互联网路由器来到基站的，还可以是从相邻接入网网元来到基站的。
在该步骤中，基站还可能收到以下至少之一：UE的空口能力信息、UE的寻呼图样信息。

UE接收寻呼消息，根据UE的寻呼标识确定是否正在被网络侧寻呼(被网络侧寻呼通常意味着UE需要和网络侧进行通信以便接收下行信令或数据)，UE进一步将接收到的C-RNTI作为自身的标识，以便使用新分配的用于无线资源调度的标识(C-RNTI)来解码PDCCH。UE还根据接收到的上行专用反馈资源信息进行上行反馈资源配置。
步骤202，基站发送无线资源调度信息，所述无线资源调度信息包括：为所述UE分配的下行物理资源信息，例如PDCCH/DCI，其中使用在寻呼消息中携带的分配给UE的用于无线资源调度的标识；例如C-RNTI通过DCI的CRC隐含携带；
UE使用上一步获取的用于无线资源调度的标识(C-RNTI)解码PDCCH，解码PDCCH的方法可采用业界周知的方法(可以参见3GPP TS36.211/36.212/36.213协议)，在此不再赘述。
UE接收到无线资源调度信息(DCI)后，根据DCI中指示的物理资源指示、MCS等用于接收PDSCH的信息准备接收下行空口数据。
步骤203，基站发送下行空口数据；
UE根据基站为UE分配的下行物理资源信息接收下行空口数据，例如UE根据DCI中指示的物理资源指示、MCS等用于接收PDSCH的信息接收下行空口数据，并进行接收正确或错误判别。在接收正确后向基站发送专用的上行反馈(由上一步所配置)并且将接收到的传输块投递给上层协议(MAC/RLC/PDCP)进行处理；如果接收错误，则不发送专用的上行反馈，并且缓存接收到的数据以便和后续重传数据进行合并和解码。
步骤204，基站尝试接收为UE配置的专用反馈，例如专用的RA(Random-Access，随机接入)preamble(前导码)，如果接收到专用的RA preamble，则表明UE接收成功，则停止后续重传并跳到步骤206；
步骤205，网络侧在专用的RA preamble接收超时后(即在规定时间内 未接收到预期的专用RA preamble后)，重传下行空口数据；规定的时间可以是网络侧和UE都支持的TTI的整数倍，例如4×TTI。步骤204和205被重复直到达到最大重传次数。
步骤206，网络侧结束传输，释放前面分配的UE调度标识和专用反馈资源(意味着C-RNTI和专用RA preamble只是临时使用)，并可以向业务或信令发起方报告传输结果，其中包括是否成功进行了下行传输的指示。在指示传输失败时，则还携带失败的原因，例如下行资源不足，或者达到最大重传次数。
在上述过程中，专用的RA preamble用于表明UE接收成功，另一种替代方法是使用专用的RA preamble以表明UE接收不成功，则步骤204和205将被替换成：
步骤204’，网络侧尝试接收为UE配置的专用反馈，例如专用的RA preamble，如果接收到专用的RA preamble，则表明UE接收不成功，则跳到步骤205’，如果在规定时间内未接收到专用的RA preamble，则表明UE接收成功，则停止后续重传并跳到步骤206；
步骤205’，网络侧在接收到专用的RA preamble后重传下行空口数据。步骤204’和205’被重复直到达到最大重传次数。
还有一种替代方法是为UE分别配置代表接收成功和接收不成功的两个专用RA preamble，具体过程不再赘述。

步骤700，有下行业务数据或信令到达基站。
该下行业务数据或信令可以是通过寻呼消息或其它S1接口消息从核心网来到基站的，也可以是从业务服务器或互联网路由器来到基站的，还可以是从相邻接入网网元来到基站的。在该步骤中，基站还可能收到以下至少之 一：UE的空口能力信息、UE的寻呼图样信息。
步骤701，基站根据UE的空口能力和寻呼图样发送寻呼消息，其中，寻呼消息包括：新分配给UE的用于无线资源调度的标识，例如C-RNTI。寻呼信息还可以包括：为UE配置的上行专用反馈资源信息，例如专用的随机接入前导(RA preamble)索引。寻呼消息中还可以携带UE的寻呼标识，例如IMSI、IMEI、或者P-TMSI。
UE根据接收到的上行专用反馈资源信息进行上行反馈资源配置。
UE接收寻呼消息，根据UE的寻呼标识确定是否正在被网络侧寻呼(被网络侧寻呼通常意味着UE需要和网络侧进行通信以便接收下行信令或数据)，UE进一步将接收到的C-RNTI作为自身的标识，以便使用新分配的用于无线资源调度的标识(C-RNTI)来解码PDCCH。
步骤702，基站尝试接收为UE配置的专用反馈，例如专用的RA preamble，如果接收到专用的RA preamble，则表明UE接收寻呼消息成功，则基站跳到步骤704。
步骤703，基站在专用的RA preamble接收超时后(即在规定时间内未接收到预期的专用RA preamble后)，重新发送针对该UE的寻呼消息；步骤702和703被重复直到达到该UE的寻呼最大重传次数或者超出UE的寻呼图样中的可用寻呼窗，然后跳到步骤707。
步骤704，基站发送无线资源调度信息，所述无线资源调度信息包括：为所述UE分配的下行物理资源信息，例如PDCCH/DCI，其中使用在寻呼消息中携带的分配给UE的用于无线资源调度的标识；例如C-RNTI通过DCI的CRC隐含携带。
步骤705，网络侧发送下行空口数据。
步骤706，网络侧在预定的间隔时间后，重传下行空口数据；预定的间隔时延可以是0，也可以是网络侧和UE都支持的TTI的整数倍。步骤706被重复直到达到最大重传次数或者下行传输超时。
步骤707，基站结束传输，释放前面分配的UE调度标识和专用反馈资源(意味着C-RNTI和专用RA preamble只是临时使用)，并可以向业务或 信令发起方报告传输结果，其中包括是否成功进行了下行传输的指示。在指示传输失败时，则还携带失败的原因，例如下行资源不足，或者寻呼达到最大重传次数或寻呼超时。
在该实施例中，UE是支持快速下行传递的任何类型终端，例如移动互联网终端，比如智能手机，也可以是物联网或车联网终端。
实施例八
该方案是以上实施例方案的综合，其中，基站从业务发起方接收的业务消息或业务数据中还可以包括空口传输方案指示信息，则网络侧根据所述空口传输方案指示信息确定空口传输方案，即采用实施例一至七的哪一种方法。
其中，业务发起方可以包括核心网，或者业务服务器，或者互联网路由器，或者其它接入网网元。
