Description

动态调度的方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种动态调度的方法及装置。
背景技术
在3GPP LTE中，引入了单小区点到多点传输(Single Cell Point to Multipoint，简称为SC-PTM)，SC-PTM技术用于实现在单小区(a single cell)中传输点到多点的下行多媒体广播多播(Multimedia Broadcast Multicast Service，简称为MBMS)业务。SC-PTM引入了两种逻辑信道，即单小区多播控制信道(Single Cell-Multicast Control Channel，简称为S C-MCCH)和单小区多播传输信道(S ingle Cell-Multicast Traffic Channel，简称为SC-MTCH)。在长期演进(Long Time Evolution，简称为LTE)中，SC-MCCH与SC-MTCH都通过物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)承载。
一个SC-MTCH信道承载一个MBMS业务的数据。在LTE中，SC-MTCH的调度信息包括：调度周期以及起始偏移，可能被调度的持续duration时间区间长度OnDurationTimer，以及UE在成功接收到一个SC-MTCH的下行数据后等待的时间长度(drxInactivityTimerSCPTM)。图1相关技术LTE系统中SC-MTCH信道的调度示意图，如图1所示，eNB在SC-MTCH调度信息指定的资源内的任意一个无线子帧内均可调度承载某个MBMS业务的SC-MTCH的PDSCH信道，UE在成功接收到的该业务的一个下行数据后，继续等待上述drxInactivityTimerSCPTM时间长度，直到该时间超时或接收到该业务的一个新的数据。在所述的drxInactivityTimerSCPTM运行期间，UE需要持续的对PDCCH信道进行检测，以便发现基站用于调度下一个SC-MTCH数据而发送的PDCCH信令。
在NB-IoT或eMTC中，对于调度SC-PTM中SC-MTCH信道，存在 以下的问题：(1)在SC-PTM中为了增强覆盖的UE的接收，同一个PDCCH信令和PDSCH信道数据都需要重复发送多次，因此在调度PDSCH的PDCCH信令中，除了指示PDSCH信道所使用的时域频域资源，调制编码MCS之外，还指示了此次调度的PDSCH的重复次数Repetition number，以及调度发送PDSCH的时间起点，即调度定时scheduling delay；(2)NB-IoT和eMTC都采用了窄带系统配置，导致在频域上可用的资源非常有限。
基于此，图2相关技术中NB-IoT或eMTC中动态调度的示意图，如图2所示，在NB-IoT和eMTC中，为了保证在NB-IoT和eMTC中增强覆盖的UE的接收，其动态调度过程中涉及的PDCCH调度和相应的PDSCH信道调度都需要重复多次，且在时域上前后错开，因此每一次动态调度所需的时间较长，相比传统LTE中一个子帧内完成PDCCH指示和相应的PDSCH调度，在NB-IoT中一次完整的动态调度需要几十个子帧重复发送PDCCH，以及随后上百个子帧重复发送相应的PDSCH。可见，在UE接收PDSCH信道的过程中，至少相当一段时间内UE处于接收前一次动态调度的SC-MTCH数据的状态；而在此时，基站在调度下一个SC-MTCH数据的过程中，由于NB-IoT和eMTC窄带的资源限制导致小区内没有足够资源用于调度的问题。
另一方面，对于NB-IoT和eMTC，如果按照现有技术中对InactivityTimer的定义，UE需要在不可能出现下一个SC-MTCH数据调度的较长时间内无效的监听PDCCH信道，从而造成UE电池的极大浪费。
针对相关技术中的上述问题，目前尚未存在有效的解决方案。

在本实施例的在一个可选实施方式中，本实施例的方法还可以包括：

上述的在持续的接收PDCCH或PDSCH，是指UE在接收PDCCH或PDSCH信道的多次重复发送的过程中，即UE根据调度信息的指示或预设的发送次数来接收所述的PDCCH信道或PDSCH信道的多次重复重复发送的过程中。
如果UE在的非活动定时器运行期间没有接收到任何调度SC-MTCH的PDCCH信令，则所述非活动定时器超时后，UE退出接收SC-MTCH的状态，即退出此次调度周期内接收SC-MTCH。

下面结合本发明实施例的具体实施例5和实施例6对上述实施例1至4进行详细说明；
实施例5
图8是根据本发明实施例的动态调度的示意图一，如图8所示，基站配置SC-MTCH信道的调度周期、以及以onDurationTimer表示的SC-MTCH的发送窗口。具体如何配置SC-MTCH的发送窗口的偏移长度等不在本发明的范围之内。
基站配置SC-MTCH信道专用的扰码G-RNTI。
UE在上述配置的SC-MTCH的发送窗口内持续接收PDCCH信道，并检测需要接收的SC-MTCH信道的G-RNTI加扰的DCI。
在本实施例中，UE在PDCCH信令指示的一次SC-MTCH数据发送的第一个无线子帧之后的第M个可用子帧，或第M个子帧，或第M个有效子帧，或M个时间单位后，启动或重启所述的非活动定时器T。
在图8中，UE首先检测到PDCCH信令指示的SC-MTCH的一次调度，并通过PDCCH信道指示的内容，即PDCCH信令DCI指示的scheduling delay，或协议约定，可知调度的PDSCH开始调度的子帧位置。在图8中，该子帧位置为t1。
则UE在t1时刻(子帧)之后的第M个子帧或M个时间单位后，启动或重启非活动定时器T。
在上述的非活动定时器运行期间，UE持续检测PDCCH，并检测到G-RNTI加扰的PDCCH信令，该信令指示PDSCH的调度从t2时刻的子帧开始，则UE在t2之后的第M个子帧，或M个时间单位后，即t3时刻，启动或重启非活动定时器T。
以此类推，直到UE在非活动定时器T运行期间，没有检测到新的所述G-RNTI加到的调度SC-MTCH的PDCCH信令。
如果UE在持续的接收调度所述SC-MTCH的PDCCH或承载所述SC-MTCH的PDSCH期间，或已经接收到调度SC-MTCH的PDCCH信令，在等待接收器调度的PDSCH时，所述的非活动定时器T超时，UE不做任何处理，即继续保持当前的状态，继续接收PDCCH，或PDSCH。在图8中，第一次非活动定时器超时时，UE已经成功接收PDCCH信令，并正在等待接收其调度的PDSCH数据部分，因此该定时器超时对UE不造成任何影响，UE不做处理，继续保持在等待接收PDSCH的状态。
而在非活动定时器第二次超时时，UE在非活动定时器运行期间没有检测到用于调度所述SC-MTCH的PDCCH信令，此时，UE退出接收SC-MTCH的状态。
实施例6
图9是根据本发明实施例的动态调度的示意图二，如图9所示，本实施例和实施例5的区别在于：
UE在所述的非活动定时器运行期间，如果成功接收到需要接收的SC-MTCH的G-RNTI加扰的PDCCH信令DCI，则UE停止所述的非活动定时器的运行。
即UE在接收到调度所述的SC-MTCH的PDCCH信令后，不需要继续接收PDCCH信道以检测所述SC-MTCH对应的G-RNTI加扰的DCI，直到所述的非活动定时器重新启动后，再继续接收PDCCH信道。
通过应用本发明提供的方法，UE在成功接收一个PDCCH调度的SC-MTCH数据后，只需要在必要的时间范围内持续监测PDCCH信道，以接收后续可能的SC-MTCH调度，避免了在长时间范围内持续检测PDCCH信道而造成的电池的浪费。
需要说明的是，上述实施例5和实施例6仅仅是以NB-IoT或eMTC系统中的SC-MTCH信道的动态调度与接收为例，其他所有满足如下条件 信道的调度：动态调度该信道的控制信道信令、与承载该信道数据的数据信道的一次发送，需要在时域中的多个无线子帧上重复。即控制信道信令和数据信道分别重复若干次以构成一次完整的调度，控制信道和数据信道的重复在时域上错开。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
步骤S1：在用户设备UE接收信道A数据的过程中，在预设时刻触发启动或重新启动预设长度的非活动定时器；
步骤S2：在非活动定时器运行期间，接收基站发送的物理下行控制信道PDCCH信令并检测调度信道A的下行控制信息DCI。
可选地，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各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中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于 本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。

    所述信道A的一次调度传输中最后一个重复发送的无线子帧的前续第M个子帧或前续第M个单位时间的时刻；
    所述信道A的一次调度传输中最后一个重复发送的无线子帧的后续第M个子帧或第M个单位时间的时刻；
    所述信道A的一次调度传输中的第一个无线子帧之后第M个无线子帧或第M个单位时间的时刻；
    其中，所述M为大于或等于0的整数。
  15. 一种动态调度的装置，应用于基站侧，其中，包括：
    调度模块，设置为动态调度的信道A；
    发送模块，设置为向用户设备UE发送物理下行控制信道PDCCH信令。
  16. 根据权利要求15所述的装置，其中，
    所述发送模块，还设置为在非活动定时器运行期间向所述UE发送所述PDCCH信令，其中，所述非活动定时器由所述UE在预设时刻触发启动或重新启动。
  17. 一种存储介质，其特征在于，所述存储介质包括存储的程序，其中，所述程序运行时执行权利要求1至8中任一项所述的方法。
