Abstract

本申请实施例提供了一种信息传输方法，包括：RAN设备为发送终端的数据调度该终端以生成调度指示；且根据调度指示对终端的数据进行组包，当存在待传输信息，RAN设备还确定组包后的MAC数据包是否包括足以发送待传输信息的空余域，当MAC数据包包括足以发送待传输信息的空余域时，RAN设备将该待传输信息组装到MAC数据包下发给终端。可见，RAN设备在调度终端之后，如果为终端分配的资源中存在多余资源，即根据调度指示组包后的MAC数据包包括空余域，则利用多余资源发送待传输信息，即将待传输信息组装到MAC数据包中。如此可以减少专门因该待传输信息调度终端的几率，节省调度资源，同时提高了空口资源的利用率。

Description

信息传输方法及装置 技术领域
本发明实施例涉及无线通信技术领域，尤其涉及信息传输方法及装置。
背景技术
在无线通信系统中，基站为终端分配无线资源以实现数据的传输，该无线资源的分配过程又称为调度过程。调度可以包括上行调度和下行调度，其中上行调度用于为终端分配上行资源，以便终端在该上行资源上发送数据，下行调度用于为终端分配下行资源，以便基站利用该下行资源给终端发送数据。
目前，在下行调度中，存在以下情况：基站没有待发送的业务数据，仅为了发送某种信息而进行下行调度。
例如，现有技术中，基站周期向终端发送时间提前量(timing advance，TA)，当发送周期到达时，尽管基站没有业务数据需要发送给终端，基站也需要启动下行调度，为终端分配下行资源，造成调度资源的浪费。尤其在基站承载大量终端的情况下，每个终端的TA都需要周期下发，且在下行调度时，资源都是以资源块(resource block，RB)或资源块组(resource block group，RBG)为单位进行分配的，分配的资源远大于发送TA所需要的资源(发送TA所需要的资源通常为2字节)，因此还会存在空口资源的浪费。
发明内容
有鉴于此，本发明实施例提供一种信息传输方法及装置，以期减少调度资源和空口资源的浪费。
第一方面，提供一种信息传输方法，包括：RAN设备为发送终端的数据调度该终端以生成调度指示；且根据调度指示对终端的数据进行组包，当存在待传输信息，RAN设备还确定组包后的MAC数据包是否包括足以发送待传输信息的空余域，当MAC数据包包括足以发送待传输信息的空余域时，RAN设备将该待传输信息组装到MAC数据包下发给终端。
第二方面，提供一种信息传输方法，包括：终端接收RAN设备发送的MAC数据包，该MAC数据包包括包头和负载，其中负载包括第一待传输信息和调度触发数据，且该调度触发数据包括终端的业务数据和/或第二待传输信息，其中第一待传输信息通过为调度触发数据分配的资源中的多余资源发送给终端；终端解析该MAC数据包，获得第一待传输信息。
第三方面，提供一种信息传输装置，位于无线接入网RAN设备，包括调度单元，组包单元和发送单元，其中调度单元用于为发送终端的数据调度终端以生成调度指示；组包单元，用于根据调度指示对该终端的数据进行组包，且确定组包后的MAC数据包包括空余域，且在存在待传输信息，且该空余域足以发送待传输信息时，用于将该待传输信息组装到MAC数据包中；发送单元，用于向终端发送该MAC数据包。
第四方面，提供一种信息传输装置，位于终端，包括接收单元和解析单元，其中接收单元用于 接收RAN设备发送的MAC数据包，该MAC数据包包括包头和负载，其中负载包括第一待传输信息和调度触发数据，且调度触发数据包括终端的业务数据和/或第二待传输信息，其中第一待传输信息通过为调度触发数据分配的资源中的多余资源发送给终端；解析单元，用于解析MAC数据包，获得第一待传输信息。
可见，在以上各个方面，RAN设备在调度终端之后，如果为终端分配的资源中存在多余资源，即根据调度指示组包后的MAC数据包包括空余域，则利用多余资源发送待传输信息，即将待传输信息组装到MAC数据包中。虽然RAN设备在调度终端时并没有考虑该待传输信息，但只要有多余的资源可以容纳该待传输信息，则便利用该空余资源发送待传输信息，如此可以减少专门因该待传输信息调度终端的几率，节省调度资源，同时提高了空口资源的利用率。
以上确定组包后的MAC数据包是否包括空余域的过程，并不在完成组包后确定的，而是一种预先估计组包后的MAC数据包是否包括空余域。
此外，以上数据即为调度触发数据，也就是触发RAN设备为终端分配资源的数据，其可以包括终端的业务数据，也可以包括其它待传输信息(或第二待传输信息)。
以上RAN设备将待传输信息组装到MAC数据包的过程中，可以将待传输信息组装成MCE，且设置MAC数据包的包头，用以指示该MCE的位置。
此外，该MCE可以设置于MAC数据包的业务数据之前，如此可以与现有MAC数据包结构兼容。当然，也可以设置在业务数据之后。
当以上待传输信息为周期发送的信息时，可以在待传输信息的发送周期到达之前，将待传输信息组装到MAC数据包中发送。如此，可以减少该待传输信息的周期到达时，专门为该待调度周期调度终端的几率。可以设置发送定时器来控制以上发送周期，且在将待传输信息组装到MAC数据包中发送之后，重置发送定时器。此时，在以上第三方面的装置中，还可以设置重置单元，用于执行重置发送定时器的操作。
此外，如果发送定时器到时，说明此段时间内并没有机会调度终端，或者即使调度了终端也没有足够大小的空余资源用于发送待传输信息，此时，可以为发送待传输信息调度终端。则在以上第三方面，调度单元便可以在这种情况下，执行调度终端操作。
该待传输信息的发送周期可以相对于现有技术的发送周期延长预设的容忍时间，以在该容忍时间内寻求发送该待传输信息机会来发送该待传输信息，如此，可以进一步减少专门因该待传输信息而调度终端的机会，进一步节省了调度资源。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图，对本发明实施例中的技术方案进行描述，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端，又称之为用户设备(user equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
2)、无线接入网(radio access network，RAN)设备是一种将终端接入到无线网络的设备，又称之为基站，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(base band unit，BBU)。此外，还可以包括Wifi接入点(access point，AP)等。
3)待传输信息是指业务数据以外需要调度终端进行发送的信息。例如，媒体接入控制(media access control，MAC)层的信息，如，MAC控制元(MAC control element,MCE)可以承载的信息，该MCE可以承载的信息例如包括TA命令、非连续接收(discontinuous reception，DRX)命令等。
4)空余域是指数据包中有效字段以外的区域，例如，现有技术中补丁所占的区域。
5)调度指示：又可以称为组包指示，是根据调度结果(或称为资源分配结果)产生的信息，用于通知无线链路控制(radio link control，RLC)层和MAC层调度结果，例如对调度的终端的承载的组包大小，当前传输时间间隔(Transmission Time Interval，TTI)哪些终端得到了调度等。
6)“多”是指两或两以上。例如，多个是指两个或两个以上，多次是指两次或两次以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
请参考图1，其为本申请实施例提供的一种通信系统的示意图。如图1所示，该系统包括RAN 设备110和终端120，其中终端120通过RAN设备110接入到无线网络中，且通过无线网络与其它终端通信，或者获得外网(例如因特网)的服务等。RAN设备110承载的终端可以有多个，RAN设备110可以调度每个终端，为其分配无线资源，以进行上下行传输。
在下行传输过程中，RAN设备110将终端的数据进行封装得到数据包以进行传输。请参考图2，其为本申请实施例给出的一种封装后得到的MAC数据包的结构示意图。如图2所示，该数据包200包括MAC头和MAC负载，其中MAC负载可以包括MCE和MAC业务数据单元(service data unit，SDU)。MCE用于承载非业务数据，MAC SDU用于承载业务数据。
RAN设备110通常以RB或RBG为单位分配资源，这种分配方式往往会使得分配给待调度的终端的资源未被全部占用，存在多余资源的情况。此时，在组包完成后会以打补丁(padding)的方式来解决多余资源的问题，如图2所示，该MAC负载中还包括补丁。
在下行调度中，RAN设备110除了在有业务数据需要发送时，调度终端120，还在有某类信息需要发送时，也调度终端120，为其分配资源。将这类需要调度终端进行发送的信息统称为待传输信息。这类信息即使在没有待发送的业务数据时，RAN设备110也会调度终端120以为发送这类信息分配资源。如此，导致调度资源和空口资源的浪费。
以TA命令的发送为例，RAN设备110周期向终端120发送TA命令，当发送周期到达时，如果恰好有该终端120的业务数据待发送，RAN设备110会考虑TA命令和业务数据来调度终端120，为其分配资源，并将业务数据和TA命令组成如图2所示的MAC层的数据包，其中业务数据分装成MAC SDU，TA命令承载于MCE，多余资源对应的区域以补丁补充。这里MCE的数量和MAC SDU的数量仅为示例，并不对这些数量做任何限制，且MCE或MAC SDU可以为零。如果发送周期到达时，RAN设备110没有该终端120的业务数据待发送，RAN设备110也会调度终端120，为其分配资源，用以发送TA命令。也就是说RAN设备110需要专门为该TA命令的下发调度终端。RAN设备110承载的终端越多，需要发送的TA命令越多，导致专门为TA命令调度终端的情况越多，如此，造成调度资源和空口资源的浪费。
目前资源分配的方式往往使得90％以上的数据包存在补丁，本申请实施例利用补丁所占用的资源，即多余资源，将待传输信息通过这些多余资源发送给终端，如此，减少了需要专门为了待传输信息调度终端的情况，节约了调度资源，更高效的利用了空口资源。例如，RAN设备因为业务数据调度终端；完成调度后，根据调度指示对待发送的终端的数据进行组包，如果此时发现有待传输信息的存在，则将组包后原来需要打补丁的资源用于发送待传输信息。如此，减少了专门针对待传输信息调度终端的情况，节约了调度资源，更高效的利用了空口资源。
请参考图3，其为本申请实施例提供的一种信息传输方法的流程图。如图3所示，该方法包括如下步骤：
S310：RAN设备为发送终端的数据调度该终端以生成调度指示；
S320：RAN设备根据调度指示对终端的数据进行组包，且确定组包后的MAC数据包是否包括空余域；
S330：当存在待传输信息，且MAC数据包包括空余域，该空余域足以发送待传输信息时，RAN 设备将待传输信息组装到MAC数据包中。其中，空余域足以发送待传输信息是指该空余域的大小大于或等于待传输信息所需的大小。
S340：RAN设备向终端发送MAC数据包。
在以上步骤S310中，数据可以包括业务数据，还可以包括其它待传输信息。RAN设备在缓存区有终端的业务数据待发送时，会调度该终端以为终端分配资源，用以发送该终端的业务数据，当然如果此时有其它待传输信息需要调度时，RAN设备会同时考虑该其它待传输信息进行调度。调度通常在层2进行，且调度之后会产生调度指示，该调度指示又可以称为组包指示，用于通知无线链路控制(radio link control，RLC)层和MAC层调度结果，例如对该终端承载的组包大小，当前传输时间间隔(Transmission Time Interval，TTI)哪些终端得到了调度等。以便RLC层根据该调度指示将终端承载上的数据组成RLC分组数据单元(Packet Data Unit，PDU)，传送给MAC层；MAC层根据调度指示，将RLC PDU组成MAC PDU，即MAC数据包，通过物理层进行传输。此时，如果仅以业务数据，组成的数据包不包括MCE，如果即包括业务数据又包括其它待传输信息，组成的数据包包括MCE和MAC SDU。
因此，在以上步骤S320中，RAN设备的MAC层便可以根据调度指示对终端的数据进行组包。该组包过程并不是一个按照图2进行排列的过程，而是各个部分之间可以独立的进行，例如MAC头，MCE和MAC SDU分别进行组装，而后确定这些部分的总大小，如果总大小小于调度指示所指示的组包大小，则存在空余域，此时可以进一步判断空余域的大小是否足以发送待传输信息。
如果空余域足以发送待传输信息，RAN设备无需再因该待传输信息调度终端，而是直接将该待传输信息组装到MAC数据包中，即以上步骤S330。在以上步骤S330中，RAN设备可以将待传输信息组装成MCE，且设置MAC头，即MAC数据包的包头，用于指示该MCE的位置。为了与现有MAC数据包结构兼容，MCE可以位于MAC SDU的前面。当然也可以位于MAC SDU的后面，即直接占用补丁的区域，此时，需要设置MAC头来指示该区域包括MCE。
在以上步骤S340中，RAN设备将MAC数据包发送给终端，以便终端解调该MAC数据包获得该待传输信息。
需要说明的是，在以上步骤S310中，RAN设备也可能仅因为其它待传输信息而调度终端，此时，相当于将需要多次调度的待传输信息合并在一次调度中发送，如此也可以节约调度资源，提高空口利用率。
可选的，以上待传输信息可以为周期发送的信息，例如，TA命令。这类信息在发送周期到达前，即使产生RAN设备也不会因此调度终端，而是当发送周期到达时，才会调度终端进行发送。但是数据业务的调度并不一定会刚好在该TA命令的发送周期到达时发生，因此会导致专门因为该待传输信息而调度终端的情况发生。本申请，在该调度信息的发送周期到达前，如果RAN设备调度了终端，且组成的MAC数据包中有足以发送该调度信息的空余域，则利用该空余域发送该待传输信息。
此外，如果可以容忍，也可以在发送周期到达，而没有其它数据需要调度时，预设容忍时间，在该容忍时间内如果有其它数据需要调度时，借用其它数据调度的机会，发送该待传输信息。此时，相当于延长了待传输信息的发送周期，如此，且在更长的发送周期里面寻求发送该待传输信息机会 来发送该待传输信息，如此，可以进一步减少专门因该待传输信息而调度终端的机会，进一步节省了调度资源。
当然，以上待传输信息也可以为非周期发送的信息，当该待传输信息产生时，如果没有其它数据需要调度，例如没有业务数据需要调度，则可以延迟一段时间后，利用其它数据的调度机会发送该待传输信息。此方式尤其适用于对时延要求不敏感的信息。该延迟的时间也可以预设，当超过预设时间之后，如果仍然没有调度机会，则调度终端，为该待传输信息分配资源。
在以上方法中，如果待传输信息组装到MAC数据包后，空余域仍未被占满，也就是空余域的大小大于待传输信息所需时，未被占满的部分可以仍然通过补丁补充。
下面以待传输信息为TA命令为例，来详细描述以上方法的一种应用场景。请参考图4，其为本申请实施例提供的一种TA命令发送方法的流程图。如图4所示，该方法包括如下步骤：
S410：RAN设备向终端发送初始TA，且为终端配置TA命令的发送周期。该发送周期可以通过发送定时器控制，该定时器的时长即为TA命令的发送周期。
例如，该发送周期可以根据需要配置，本申请不做限制，举例而言可以配置为600ms，900ms等。RAN设备为终端配置的初始TA可以通过随机接入响应发送给终端。随后RAN设备根据发送周期周期性的向终端发送TA命令，用于调整TA。
S420：RAN设备调度终端，生成调度指示。其中，该调度并非因TA命令而触发，例如可以因为数据业务的发送而触发，也就是说RAN设备有终端的业务数据需要发送给终端，从而调度终端为该终端分配资源，此时由于TA命令的发送周期并未到达，因此调度时并不会考虑TA命令。
S430：RAN设备根据调度指示进行组包，此时TA命令已经生成但TA命令的发送周期并没有到达，RAN设备确定组包后的MAC数据包是否包括足以发送该TA命令的空余域。
在调度过程中，RAN设备根据RLC的缓存估计来为终端分配资源，生成调度指示，并根据该调度指示对终端的数据进行组包，此时有TA命令生成，确定组包后的MAC数据包是否存在足够发送TA命令的空余域，例如是否存在两个字节以上的空余域。如果存在，则执行以下步骤S440，组装TA命令到MAC数据包中。
S440：当包括足以发送该TA命令的空余域时，RAN设备将TA命令组装到MAC数据包中下发给终端。
此时，可以将TA命令组装成MCE，且设置于MAC SDU之前，并通过MAC头指示该MCE的位置。
S450：RAN设备重启发送定时器。
既然TA命令通过MAC数据包发送给了终端，RAN设备可以维护下一个发送周期，即重启发送定时器。如果在发送定时器超时时，RAN设备仍然没有找到机会下发TA命令，则表明此段时间内并没有机会调度终端，或者即使调度了终端也没有足够大小的空余资源用于发送TA命令，则按现有技术调度终端，为该TA命令分配资源，即执行以下步骤S460。
S460：发送定时器到时时，RAN设备为发送TA命令调度终端。
可见，利用以上方法发送TA命令时，可以有效利用多余资源，提高了空口资源的利用率，此外，可以减少专门因TA命令的调度终端的几率，节省了调度资源。
本申请还提供一种信息传输方法，由终端执行，请参考图5，其包括如下步骤：
S510：终端接收RAN设备发送的MAC数据包，所述MAC数据包包括包头和负载，其中所述负载包括第一待传输信息和调度触发数据，且所述调度触发数据包括所述终端的业务数据和/或第二待传输信息，其中所述第一待传输信息通过为所述调度触发数据分配的资源中的多余资源发送给所述终端；
S520：终端解析MAC数据包，获得第一待传输信息。
需要说明的是，这里的调度触发数据即为触发RAN设备为终端分配资源的数据，其可以包括终端的业务数据，也可以包括第二待传输信息，即以上实施例中的其它待传输信息。
可见，在以上方法中，终端通过RAN设备为其它数据分配的资源中的多余资源接收第一待传输信息，如此可以节省专门针对该第一待传输信息调度终端的几率，节约待调度资源，同时提高空口资源的利用率。
关于第一待传输信息的位置以及内容同以上实施例，在此不再赘述。
请参考图6，其为本申请实施例提供的一种信息传输装置的结构示意图，该装置位于RAN设备，且如图6所示，该装置600包括调度单元610、组包单元620和发送单元630。其中，调度单元610用于为发送终端的数据调度该终端以生成调度指示；组包单元620用于根据调度指示对终端的数据进行组包，且在存在待传输信息时，确定组包后的MAC数据包是否包括足以发送所述待传输信息的空余域。进一步在MAC数据包包括足以发送所述待传输信息的空余域时，将待传输信息组装到MAC数据包中；发送单元630用于向终端发送该MAC数据包。
其中，组包单元620可以将待传输信息组装成MCE，并设置MAC数据包的包头，以指示该MCE的位置。较佳的，当该MAC数据包括业务数据时，该MCE可以位于MAC数据包中的业务数据，即MAC SDU之前，如此，可以与现有MAC数据包结构兼容。当然，也可以将其设置在MAC SDU之后，占据本来补丁的位置，本申请不做任何限制。
此外，触发调度单元610调度终端的数据同以上实施例的描述，可以为业务数据，也可以为其它待传输信息，当然也可以两者都包括。
关于待传输信息的描述同以上方法实施例，其可以为周期发送的信息，也可以为非周期发送的信息。当其为周期发送的信息时，组包单元620可以在该调度信息的发送周期到达之前，将待传输信息组装到MAC数据包中。且该发送周期可以延长预设的容忍时间。
此外，如图7所示，当待传输信息的发送周期通过发送定时器控制时，以上装置600还可以包括重置单元640，用于在将所述待传输信息组装到所述MAC数据包中之后重置该发送定时器。
如果发送定时器到时，说明此段时间内并没有机会调度终端，或者即使调度了终端也没有足够大小的空余资源用于发送待传输信息，此时，调度单元610还用于为发送待传输信息调度终端。
需要说明的是，以上各个单元可以为单独设立的处理元件，也可以集成在RAN设备的某一个芯片中实现，此外，也可以以软件(例如，程序代码)的形式存储于RAN设备的存储器中，由RAN设备的某一个处理元件调用并执行以上各个单元的功能。此外各个单元可以集成在一起，也可以独立实现。这里所述的处理元件可以是一个中央处理器(Central Processing Unit，CPU)，或者是特 定集成电路(Application Specific Integrated Circuit，ASIC)，或者是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个微处理器(digital singnal processor，DSP)，或，一个或者多个现场可编程门阵列(Field Programmable Gate Array，FPGA)等。
