Description

一种数据传输方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输方法及相关设备。
背景技术
随着移动互联网和物联网产业的发展，越来越多的移动终端相互连接并分享更加丰富的数据，基于蜂窝的窄带物联网(Narrow Band Internet of Things，NB-IoT)成为万物互联网络的一个重要分支。NB-IoT构建于蜂窝网络，只消耗大约180KHz的带宽，可直接部署于全球移动通讯(global system of mobile communication，GSM)网络、通用移动通信系统(universal mobile telecommunication system，UMTS)网络或长期演进(long term evolution，LTE)网络，以降低部署成本、实现平滑升级。NB-IoT是IoT领域一个新兴的技术，支持低功耗设备在广域网的蜂窝数据连接，也被叫作低功耗广域网(Low-Power Wide-Area Network，LPWAN)。NB-IoT支持待机时间长、对网络连接要求较高设备的高效连接。
目前，在NB-IoT系统中，上下行数据传输都是基于下行控制信(Downlink Control Information，DCI)调度的。具体地，下行数据传输过程中，终端设备在窄带物理下行链路控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)盲检DCI，DCI接收成功后根据下行授权接收窄带物理下行共享信道(Narrowband Physical Downlink Shared Channel，PDSCH)数据。上行数据传输过程中，终端设备在窄带物理下行链路控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)盲检DCI，DCI接收成功后根据上行授权指示，准备窄带上行物理上行共享信道(Narrowband Physical Uplink Shared Channel，NPUSCH)数据，在指示的时频资源上发送PUSCH数据。
上述基于调度的系统，上下行调度都是先发送DCI，然后再传输PDSCH/PUSCH，根据终端设备所处覆盖等级不同，DCI传输占用的时间不同。而不同的业务对时延的敏感度不一样，对于时延敏感业务，DCI传输占用时间过长，从而导致时延不能满足要求。

如图1所示，传输信道可包括：DL-SCH(Downlink Shared Channel，下行共享信道)、BCH(Broadcast Channel，广播信道)、PCH(Paging Channel，寻呼信道)、UL-SCH(Uplink Shared Channel；上行共享信道)、RACH(Random Access Channel，随机接入信道)。
(3)物理信道：由物理层用于具体信号的传输。物理信道和承载高层信息的资源因子(Resource Element，RE)集合相对应。组成物理信道的基本实体是资源因子(RE)和资源块(Resource Block，RB)。
如图1所示，物理信道可包括：窄带物理下行控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)、窄带物理下行共享信道(Narrowband Physical Downlink Shared channel，NPDSCH)、窄带物理随机接入控制信道NPRACH(Narrowband Physical Random Access Control Channel)、窄带物理上行共享信道(Narrowband Physical Uplink Shared  channel，NPUSCH)、窄带物理广播信道(Narrowband Physical Broadcast Channel，NPBCH)窄带参考信号(Narrowband reference signal，NRS)窄带同步信号(Narrowband synchronization signal，NSS)、窄带定位参考信号(Narrowband positioning reference signal，NPRS)。
而在LTE系统中，物理信道可包括：PDCCH(Physical Downlink Control Channel，物理下行控制信道)、PDSCH(Physical Downlink Shared Channel，物理下行共享信道)、PBCH(Physical Broadcast Channel，物理广播信道)、PMCH(Physical Multicast Channel，物理多播信道)、PHICH(Physical Hybrid ARQ Indicator Channel，物理H-ARQ指示信道)、PCFICH(Physical Control Format Indicator Channel，物理控制格式指示信道)、PUCCH(Physical Uplink Control Channel，物理上行控制信道)、PUSCH(Physical Uplink Shared Channel，物理上行共享信道)、PRACH(Physical Random Access Channel，物理随机接入信道)。
(4)ALOHA协议，是随机访问或者竞争发送协议。随机访问意味着对任何站都无法预计其发送的时刻；竞争发送是指所有发送的站自由竞争信道的使用权。Aloha协议或称Aloha技术、Aloha网。分段(或时隙)ALOHA协议(Slotted ALOHA)这是对纯ALOHA协议的一个改进，思想是用时钟来统一用户的数据发送。改进之处在于，它把频道在时间上分段，每个传输点只能在一个分段的开始处进行传送。用户每次必须等到下一个时间片才能开始发送数据，每次传送的数据必须少于或者等于一个频道的一个时间分段。这样很大的减少了传输频道的冲突。从而避免了用户发送数据的随意性，减少了数据产生冲突的可能性，提高了信道的利用率。

下面结合本申请中提供的数据传输方法的实施例，对本申请中提出的技术问题进行分析和解决。
请参见图3，是本发明实施例提供的一种数据传输方法的流程示意图，可应用于上述图2中所述的通信系统，下面将结合附图3从终端设备和网络设备的交互侧进行描述，该方法可以包括以下步骤S301-步骤S303。
步骤S301：终端设备向网络设备发送RRC连接请求消息，所述RRC连接请求消息包括第一指示信息，所述第一指示信息用于指示所述终端设备的业务类型；网络设备接收终端设备发送的RRC连接建立请求。
具体地，在现有技术中，随机接入是在空闲模式或者连接模式下发起的用于建立终端设备与网络设备之间的无线连接的过程，主要是完成终端设备(如UE)取得与网络设备(如 基站)之间的上行同步和申请上行资源，即用于实现UE和网络的同步，解决冲突，分配资源(RNTI)和上行通信资源的分配。其中，RRC(Radio Resource Control)是指无线资源控制。如图4所示，图4为本发明实施例提供的一种终端设备随机接入流程示意图，包括如下5个步骤：
步骤1、UE发送随机接入前导码(Random Access preamble)，可称之为MSG1；
步骤2、基站发送随机接入响应消息(Random Access Response)，可称之为MSG2；
步骤3、UE发送RRC连接请求(RRC Connection Request)，可称之为MSG3；
步骤4、UE接收RRC连接建立(RRC Connection Setup)，可称之为MSG4；
步骤5、UE和基站之间无线资源控制连接完成(RRC Connection Complete)，可称之为MSG5。
本发明实施例，通过在上述步骤3中的RRC连接请求消息即MSG3中携带第一指示信息，而该第一指示信息用于指示终端设备的业务类型，其中业务类型可以根据终端设备当前所需要进行的业务实时变化。例如，可以分为时延敏感业和时延不敏感业务。请参见表1。
表1
Figure PCTCN2018076044-appb-000001
表1中为230MHz IoT系统应用于电力系统中时的，所涉及到的相关业务类别，以及对应的时延要求。在230MHz IoT电力系统中，目前主要解决的是用电、配电和精准负控业务，对于这三类业务，具体的业务特征如下：
(1)用电，网络侧发起，上下行多次小包交互，流程繁琐，时延容忍度高。
(2)配电，(遥控、遥测、遥信、链路测试、通信对时)网络侧发起和终端设备侧发起混合，下行小包，上行数据包大小变化范围大，对时延有一定要求，容量要求较高。
(3)精准负控(遥控、遥测、遥信)，遥控为下行业务，要求单向传输空口时延不超过33ms；遥测和遥信为上行业务，要求单向传输空口时延不超过50ms，。
从上表1可以看出，精准负荷控制业务可以划分为时延敏感业务，而用电信息采集业务等可以划分为时延不敏感业务。可以理解的是，也可以对终端设备的业务类型按照其它标准进行更多种类的划分，本申请对此不作具体限定。
步骤S302：所述网络设备向所述终端设备发送RRC连接建立消息，所述RRC连接建立消息包括第二指示信息，所述第二指示信息用于指示与所述业务类型所匹配的调度模式；所述终端设备接收网络设备发送的RRC连接建立消息。
具体地，通过在上述步骤4中的RRC连接建立消息即MSG3中携带第二指示信息，而该第二指示信息用于指示终端设备的调度模式，该调度模式与步骤S301中上报的业务类型 相匹配。例如调度模式为基于下行控制信息调度和无调度模式，其中时延敏感业务可以对应无调度模式，时延不敏感业务则可以对应下行控制信息调度模式。可以理解的是，网络设备还可以根据需求配置对应调度模式的相关参数，例如，时频资源参数、调制与编码方式参数等。
步骤S303：所述终端设备与所述网络设备根据所述调度模式进行数据传输。所述网络设备与所述终端设备根据所述调度模式进行数据传输。
具体地，终端设备和网络设备之间按照网络设备指示的调度方式进行数据的传输。具体地，可以包括以下几种方式。以下以方式一、方式二和方式三进行示例性说明：
方式一，业务类型为第一业务(例如时延不敏感业务)，上下行基于DCI的调度模式：
在一种可能的实现方式中，当业务类型为第一业务，第一业务所匹配的调度模式为下行控制信息调度模式；终端设备与网络设备根据调度模式进行数据传输，具体为：网络设备根据向终端设备发送的下行控制信息与终端设备进行上行或下行数据的传输。终端设备根据网络设备发送的下行控制信息，与网络设备进行上行或下行数据的传输。其中
在上行传输中，若基于下行控制信息调度方式，MSG4中可以包括以下配置参数：
(1)PDCCH资源配置参数，例如载波资源位置、重复次数、开始偏置等；
(2)SR资源配置参数，例如载波资源位置、重复次数、周期、开始偏置、持续时间、SR preamble开始索引、结束索引等。
在下行传输中，若基于下行控制信息调度方式，MSG4中可以包括以下配置参数：
(1)PDCCH资源配置参数，例如载波资源位置、绑定载波数、重复次数、开始偏置。
方式二，业务类型为第二业务(例如时延敏感业务)，上行为无调度模式。
在一种可能的实现方式中，当业务类型为第二业务，第二业务所匹配的调度模式为上行无调度模式；第二指示信息包括第一时频资源的信息和第一调制与编码方式的信息；终端设备与网络设备根据调度模式进行数据传输，具体为：终端设备根据第一时频资源的信息和第一调制与编码方式的信息，在第一时频资源上以第一调制与编码方式向网络设备发送上行数据。网络设备在第一时频资源上以第一调制与编码方式接收终端设备发送上行数据。其中，针对上述上行无调度模式，可以采用时隙ALOHA的方式来进行上行传输，以避免时隙冲突。其中，
在上行传输中，若基于无调度方式，MSG4中可以包括以下配置参数：
(1)PUSCH资源配置参数，例如载波资源位置、绑定载波数、MCS索引、绑定帧数、重复次数、周期、开始偏置、持续时间、竞争窗长等；
(2)PHICH资源配置参数，例如载波资源位置、重复次数、MCS索引等。
方式三，业务类型为第二业务(例如时延敏感业务)，下行为无调度模式：
在一种可能的实现方式中，当业务类型为第二业务，第二业务所匹配的调度模式为下行无调度模式；第二指示信息包括第二时频资源的信息和第二调制与编码方式的信息；终端设备与网络设备根据调度模式进行数据传输，具体为：终端设备根据第二时频资源的信息和第二调制与编码方式的信息，在第二时频资源上以第二调制与编码方式接收网络设备发送的下行数据。网络设备在第二时频资源上以第二调制与编码方式向终端设备发送下行数据。
在下行传输中，若基于无调度方式，MSG4中可以包括以下配置参数：
(1)PDSCH资源配置参数，例如载波资源位置、绑定载波数、MCS索引、绑定帧数、重复次数、周期、开始偏置、持续时间等；
(2)PUCCH资源配置参数，例如载波资源位置、重复次数等。
可以理解的是，上述第一时频资源和第一调制与编码方式，以及第二时频资源和第二调制与编码方式也可以为终端设备和网络设备之间预先约定好的，即无需通过MSG4重新只是，即MSG4只通过第二指示具体的调度模式即可，而终端设备则根据MSG4中指示的具体调度模式，使用预先约定的时频资源以及调制与编码方式进行数据传输即可。
在一种可能的实现方式中，当业务类型为第二业务，第二指示信息用于指示第二业务所匹配的调度模式为上行无调度模式；终端设备接收网络设备广播的系统消息，系统消息包括第一时频资源的信息和第一调制与编码方式的信息；终端设备与网络设备根据调度模式进行数据传输，具体为：终端设备根据第一时频资源的信息和第一调制与编码方式的信息，在第一时频资源上以第一调制与编码方式向网络设备发送上行数据；对应的，网络设备在第一时频资源上以第一调制与编码方式接收终端设备发送上行数据。本发明实施例，当业务类型为第二业务，例如第二业务为时延敏感业务，那么网络设备可以通过指示该终端设备的调度模式为上行无调度模式，在该上行无调度模式下，终端设备可以根据网络设备发送的系统消息中指示的第一时频资源的信息和第一调制与编码方式的信息，在第一时频资源上以第一调制与编码方式向网络设备发送上行数据。如此一来，便节省了终端设备需要在接收到网络设备发送的下行控制信息之后才能发送上行数据的时间，提升了通信效率。
在一种可能的实现方式中，当业务类型为第二业务，第二指示信息用于指示第二业务所匹配的调度模式为下行无调度模式；终端设备接收网络设备广播的系统消息，系统消息包括第二时频资源的信息和第二调制与编码方式的信息；终端设备与网络设备根据调度模式进行数据传输，具体为：终端设备根据第二时频资源的信息和第二调制与编码方式的信息，在第二时频资源上以第二调制与编码方式接收网络设备发送的下行数据；对应的，网络设备在第二时频资源上以第二调制与编码方式向终端设备发送下行数据。本发明实施例，当业务类型为第二业务，例如第二业务为时延敏感业务，那么网络设备可以通过指示该终端设备的调度模式为下行无调度模式，在该下行无调度模式下，终端设备可以根据网络设备发送的系统消息中指示的第二时频资源的信息和第二调制与编码方式的信息，在第二时频资源上以第二调制与编码方式接收网络设备发送的下行数据。如此一来，便节省了终端设备需要在接收到网络设备发送的下行控制信息之后才能接收下行数据的时间，提升了通信效率。

结合上述第一方面或第二方面中的任意一种实现方式，在一种可能的实现方式中，RRC连接建立请求还包括终端设备支持的信道绑定最大个数M；第一时频资源的信息包括PUSCH的信道绑定个数N，其中，M和N均为正整数，N小于或者等于M。例如，MSG3上报支持最大信道绑定数，信道绑定数代表能同时接收的信道数；基站根据终端设备能力，基于上行无调度方式，在MSG4中配置PUSCH的绑定信道数，不超过UE能力。本发明实施例，终端设备在RRC连接建立请求中除了指示终端设备的业务类型，还指示该终端设备所支持的信道绑定最大个数M，而网络设备则可以根据终端设备的能力在RRC连接建立消息中的第一时频资源的信息中包括PUSCH的信道绑定个数N，以便于根据终端设备的能力配置上行传输的相关参数。
结合上述第一方面或第二方面中的任意一种实现方式，在一种可能的实现方式中，RRC连接建立请求还包括终端设备支持的射频带宽；第一时频资源的信息包括PUSCH的跳频带宽，其中，跳频带宽的最大值小于或者等于射频带宽的值。例如，MSG3上报支持终端设备射频支持的带宽，例如支持180KHz，1MHz，12MHz；基站根据终端设备能力，基于上行无调度方式下，在终端设备支持信道绑定并且系统支持跳频时，在MSG4中配置PUSCH的跳频位图bitmap，确保任何时刻，信道绑定的任意两个载波位置不超过终端设备支持的带宽能力。本发明实施例，终端设备在RRC连接建立请求中除了指示终端设备的业务类型，还指示该终端设备所支持的射频带宽，而网络设备则可以根据终端设备的能力在RRC连接建立消息中的第一时频资源的信息中包括PUSCH的跳频带宽，以便于根据终端设备的能力配置上行传输的相关参数。

在一种可能的实现方式中，RRC连接建立请求还包括终端设备支持的信道绑定最大个数M；第二时频资源的信息包括PDSCH的信道绑定个数N，其中，M和N均为正整数，N小于或者等于M。例如，MSG3上报支持最大信道绑定数，信道绑定数代表能同时接收的信道数；基站根据终端设备能力，基于下行无调度方式，在MSG4中配置PDSCH的绑定信道数，不超过UE能力。本发明实施例，终端设备在RRC连接建立请求中除了指示终端设备的业务类型，还指示该终端设备所支持的信道绑定最大个数M，而网络设备则可以根据终端设备的能力在RRC连接建立消息中的第一时频资源的信息中包括PDSCH的信道绑定个数N，以便于根据终端设备的能力配置下行传输的相关参数。
在一种可能的实现方式中，RRC连接建立请求还包括终端设备支持的射频带宽；第二时频资源的信息包括PDSCH的跳频带宽，其中，跳频带宽的最大值小于或者等于射频带宽的值。例如，MSG3上报支持终端设备射频支持的带宽，例如支持180KHz，1MHz，12MHz；基站根据终端设备能力，基于下行无调度方式下，在终端设备支持信道绑定并且系统支持跳频时，在MSG4中配置PDSCH的跳频位图bitmap，确保任何时刻，信道绑定的任意两个载波位置不超过终端设备支持的带宽能力。本发明实施例，终端设备在RRC连接建立请求中除了指示终端设备的业务类型，还指示该终端设备所支持的射频带宽，而网络设备则可以根据终端设备的能力在RRC连接建立消息中的第一时频资源的信息中包括PDSCH的跳频带宽，以便于根据终端设备的能力配置下行传输的相关参数。
在一种可能的实现方式中，业务类型包括第一业务和第二业务，第二业务的时延要求高于第一业务。本发明实施例，通过将终端设备侧的业务类型划分为时延要求高的业务和时延要求不高的业务，以针对时延要求不同的业务匹配不同的调度模式进行数据传输。例如第一业务对应上述方式一中的上下行基于下行控制信息的调度，第二业务可以对应方式二和/在一种可能的实现方式中，当业务类型为第二业务，RRC连接建立消息包括物理上行共享信道PUSCH资源配置参数和物理HARQ指示信道PHICH资源配置参数。本发明实施例，当业务类型为第二业务，对应的调度模式可以为上行无调度模式，则RRC连接建立消息中包含了上行传输的相关配置参数。

可以理解的是，上述上行和下行的调度模式，可以根据终端设备的实际业务需求相互组合，网络设备侧可以在MSG4中同时指示上下行的调度模式，也可以只指示上行或者下行的调度模式。如下表2所示，传输模式(Transmission Mode，TM)对应的调度模式可以分将上行和下行分开指示，也可以根据终端设备的业务类型进行组合指示，本申请对此不作具限定。
