Description

一种传输数据的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种传输数据的方法和装置。
背景技术
第三代合作伙伴计划(the third generation partnership project，3GPP)对未来的第五代(5th generation，5G)的典型场景用例归纳为以下三种：增强的移动宽带(enhanced mobile broadband，eMBB)业务，海量机器类型连接(massive machine type communication，mMTC)业务以及超可靠低时延通信(ultra-reliable and low latency communications，URLLC)业务，在这些场景下，数据传输过程中如何降低传输时延成为了新的问题。
例如，对于物联网的终端(机器类型通信(machine type communication，MTC)或者窄带互联网(narrow band internet of things,NB-IoT)的终端)，其对于语音、移动性、速率等没有过高的要求，但对于成本、覆盖、终端能耗等方面有更高的诉求。考虑到此类终端需要和网络设备建立网络连接后才可以向网络设备发送数据，终端与网络设备建立网络连接的过程可能会消耗较多的信令，这样可能增加数据传输的时延。
发明内容
本申请提供一种数据传输的方法和装置，以期降低数据传输过程中的时延。
第一方面，提供了一种传输数据的方法，该方法包括：终端接收来自于网络设备的第一上行授权；该终端使用该第一上行授权，向该网络设备发送待发送数据中的第一上行数据；该终端接收来自于该网络设备的第二上行授权；该终端使用该第二上行授权，向该网络设备发送第二上行数据，该第二上行数据为该待发送数据中除该第一上行数据以外的至少部分上行数据，其中，该终端处于第一状态，且该第一状态包括空闲态或者非活跃态。
本申请实施例中的传输数据的方法，终端可以在空闲态或者非活跃态时多次向网络设备发送上行数据，相比于终端进入连接态后向网络设备发送数据，有助于减少空口交互次数，从而有助于降低传输数据的时延。
本申请实施例中，网络设备可以向终端发送第二上行授权，使得终端的待发送数据在第一上行数据中无法发送完成或者发送完成后有新数据到达时，能够及时将这部分数据发送给网络设备。
在一些可能的实现方式中，该第二上行数据为该终端发送该第一上行数据后新到达的上行数据。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：该终端向该网络设备发送第一指示信息，该第一指示信息用于指示该待发送数据未发送完。
本申请实施例中，终端通过向网络设备指示待发送数据未发送完，从而网络设备可以指示终端继续停留在第一状态进行上行数据的发送，相比于终端进入连接态后向网络设备 发送数据，有助于减少空口交互次数，从而有助于降低传输数据的时延。
在一些可能的实现方式中，该第一指示信息用于指示终端希望在空闲态或者非活跃态完成数据发送；或者，该第一指示信息用于指示该终端还有进一步的上行数据；或者，该第一指示信息用于请求第二上行授权。

以下，对本申请中的部分用语进行说明：
1)、终端，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、或移动终端(mobile terminal，MT)等，是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端的举例为：手机(mobile phone)、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，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。
2)、网络设备是无线网络中的设备，例如将终端接入到无线网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、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)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、5G系统或新无线(new radio，NR)等。
在介绍本申请实施例之前，首先简单介绍几个与本申请实施例相关的概念。
调度过程：网络设备可以通过动态调度，预配置资源调度两种方式调度终端进行上行传输，例如，通过发送动态UL grant，或预配置UL grant，指示终端进行上行数据发送。
动态调度：网络设备发送上行调度授权(uplink grant，UL grant)，在物理下行控制信道(physical downlink control channel，PDCCH)上发送DCI，即动态UL grant，并且通过终端标识进行加扰，终端若成功解码该控制信息，可以获取此次上行调度对应的物理层资源大小以及所述物理层资源的时域/频域分布，以及此次上行调度传输所需的HARQ信息，从而终端进行HARQ过程，完成上行传输。
预配置资源调度：网络设备还可以通过半静态资源分配的方式预配置终端上行传输所需的资源，即预配置UL grant，应理解，所述预配置UL grant可以按周期出现，不需要终 端每次发送上行传输前都先获得上行授权。例如，网络设备可以通过无线资源控制(radio resource control，RRC)信令配置上行传输的UL grant，还可以包括预配置UL grant的周期，从而终端在所述预配置的资源调度上传输，所述方式可以是配置授权方式1(configured grant type 1)；网络设备还可以通过RRC信令配置上行传输的部分信息，例如，预配置UL grant的周期等，并且通过物理层信令携带上行传输的UL grant并激活所述上行传输的资源，从而终端在所述预配置的资源调度上传输，所述方式可以是配置授权方式2(configured grant type 2)以上两种均可以成为预配置资源调度。
需要说明的是，在本申请实施例中，“上行授权”、“上行授权消息”可理解为用于调度物理上行资源的信令，例如，用于上行授权的下行控制信息，或者，用于半静态配置的RRC信令，或者，在半静态配置方式中用于激活上行授权资源的下行控制信息等。“上行授权资源”可理解为通过上行授权指示的资源。在LTE或NR协议中，“上行授权”、“上行授权消息”和“上行授权资源”都可对应为UL grant，本领域的技术人员可理解其含义。
还需要说明的是，本申请实施例中，“协议”可以指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
图1是本申请实施例提供的一种通信系统100的示意图，如图1所示，终端130接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它终端通信。该无线网络包括RAN110和核心网(CN)120，其中RAN110用于将终端130接入到无线网络，CN120用于对终端进行管理并提供与外网通信的网关。
应理解，本申请提供的传输数据方法可适用于无线通信系统，例如，图1中所示的无线通信系统100。处于无线通信系统中的两个通信装置间具有无线通信连接，该两个通信装置中的一个通信装置可对应于图1中所示的终端130，例如，可以为图1中的终端130，也可以为配置于终端130中的芯片；该两个通信装置中的另一个通信装置可对应于图1中所示的RAN110，例如，可以为图1中的RAN110，也可以为配置于RAN110中的芯片。
以下，不失一般性，以终端与网络设备之间的交互过程为例详细说明本申请实施例。可以理解，处于无线通信系统中的任意一个终端可以基于相同的方法与具有无线通信连接的一个或多个网络设备通信。本申请对此不做限定。
应理解，对于图1所示的通信系统，网络设备可以是图1中的RAN110，终端可以是图1中的终端130。
图2是本申请实施例提供的一种网络架构的示意图，如图2所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以与基带装置集成在同一个物理装置中，或者部分拉远部分与基带装置集成。例如，在LTE通信系统中，作为RAN设备的eNB包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括RRC层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data  adaptation protocol，SDAP)层。
这些协议层的功能可以由一个节点实现，或者可以由多个节点实现；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图3所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图3，图3示出了本申请实施例提供的另一种网络架构的示意图，相对于图2所示的架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端，或者终端产生的信令可以通过DU接收后发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端或CU。以下实施例中如果涉及这种信令在CU和终端之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为物理层的数据发送给终端，或者，由接收到的物理层的数据转变而来。在这种架构下，该RRC或PDCP层的信令，可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端或者网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的网络设备。

每个小区有64个可用的preamble序列，该终端可以选择preamble，在物理随机接入信道(physical random access channel，PRACH)传输。网络设备通过系统消息告知终端当前小区可用于传输preamble的PRACH的时频资源集合，该终端发起随机接入时，选择 PRACH资源，从而发送preamble。

S240，该网络设备向该终端发送随机接入过程消息四(Msg4)。
具体而言，由于S230中该终端会携带该终端的标识信息，因此网络设备在冲突解决机制中，会通过S240中的Msg4携带该终端的标识信息以指定冲突解决中胜出的终端，而其他没有在冲突解决中胜出的终端将重新发起随机接入。可选地，Msg4还可以携带用户面数据，一种可能的方式是该用户面数据可以在NAS消息携带，该NAS消息可以包含在RRC消息中，另一种可能的方式是该用户面数据与RRC消息可以复用在一起，而并非包含在RRC消息中。

可选地，若该MsgB包含preamble标识，该终端收到MsgB后，判断MsgB中的preamble标识是否与S320中发送的preamble相同，如果相同，则认为MsgB接收成功，否则，认为MsgB接收失败，该终端可以重新触发RA过程。
可选地，若该MsgB包含冲突解决标识，该终端收到MsgB后，判断MsgB中的冲突解决标识是否与S320中发送的RRC消息匹配或者是否与S320中发送的RRC消息的前48比特匹配，如果匹配，则认为MsgA发送成功。

在介绍本申请实施例之前，先对本申请实施例中终端的几种状态进行说明。在现有的无线通信系统中，为终端定义了多种通信状态。例如，如果终端与网络设备建立了通信连接，则定义终端处于连接(connected)状态；如果终端处于待机状态，则定义终端处于空闲(idle)状态。另外，在5G通信系统中还定义了非活跃(inactive)状态，在非活跃状态下，终端可以保留与网络设备之间的通信连接的一些上下文信息。其中，在连接状态下，终端可以与网络设备能够进行连续通信。
下面介绍本申请实施例提供的传输数据的方法。
图8示出了本申请实施例提供的传输数据的方法400的示意性流程图，如图8所示，该方法400的执行主体可以是传输数据的装置(例如，终端或者用于终端的芯片或装置，网络设备或者用于网络设备的芯片或者装置)，下文以执行主体为终端和网络设备为例进行描述。该方法400包括包括以下步骤S410-S440。

可选地，该第一状态包括空闲态或者非活跃态。
可选地，该终端向该网络设备发送待发送数据中的第一上行数据，包括：在满足预设条件时，该终端向该网络设备发送该第一上行数据，其中，该预设条件包括以下一种或者多种：
预设条件一：该终端确定有该待发送数据。
该终端只要确定由待发送数据需要发送给网络设备，即可以触发S420-S440的传输数据的过程。
预设条件二：该终端确定该待发送数据的数据量小于或者等于第一预设门限值。
