Description

数据包的传输方法及通信装置
本申请要求于2018年01月12日提交中国专利局、申请号为201810032230.4、申请名称为“数据包的传输方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及数据包的传输方法、通信装置和计算机可读存储介质。
背景技术
上行免授权传输(up-link grant-free transmission)是一种“即来即走”(arrive-and-go)的上行数据发送方法。上行免授权传输又可以称之为上行无动态调度传输(up-link transmission without dynamic scheduling)或者上行无动态授权传输(up-link transmission without dynamic grant)。在上行免授权传输中，当数据到达时，终端设备不需要向基站(gNB)发送调度请求(scheduling request,SR)以及不需要等待基站发送动态授权(grant)，而是可以直接使用基站预先分配的传输资源和/或参数向基站发送数据。
基站预先为终端设备分配的传输资源和/或参数可以包括：时域周期P(periodicity)；时域资源的偏置参数(offset)；时域资源分配(time domain resource allocation)参数；频域资源分配参数(frequency domain resource allocation)、重复次数K(number of repetitions)，K>＝1；冗余版本(redundancy version，RV)序列等。
5G新空口(new radio，NR)通信技术中，终端设备有数据包需要向基站发送时，终端设备从周期P中的前K个传输时机(transmission occasion，TO)中确定数据包的首次TO，并从首次TO开始重复传输该数据包，当如下条件之一满足时，数据包的重复传输即被终止：重复传输(repetition)次数达到K次；在周期P内的第K个TO上传输完数据包的一次重复。
上述重复传输数据包的方法中，数据包的初传不是发生在周期P内的第一个TO的情况下，数据包的重复传输的次数会较少，从而影响数据包的传输可靠性。
发明内容
本申请提供一种数据包的传输方法、通信装置、计算机可读存储介质以及计算机应用程序，有助于提高数据包的传输可靠性。
第一方面，本申请提供了一种数据包的传输方法。该传输方法包括：确定时域周期内用于数据包初传的TO；从该用于数据包初传的TO开始，在该时域周期内的TO传输数据包的重复；直到该数据包的重复传输的次数达到K次和在该时域周期内的第N个TO传输了该数据包的一次重复中的任意一个条件得到满足，终止该数据包的重复传输，其中， K为配置的重复传输的最大次数，N为大于K的整数。
第二方面，本申请提供了一种数据包的传输方法。该传输方法包括：确定时域周期内用于数据包初传的TO；从所述用于数据包初传的TO开始，在该时域周期内的TO传输数据包的重复；在该时域周期内的第K个TO内传输了该数据包的一次重复之后，判断该数据包的重复传输的是否达到K次，其中，K为配置的重复传输的最大次数；如果该数据包的重复传输的次数未达到K次，在该时域周期内剩余的TO继续传输该数据包的重复，直到预定的条件中任意一个得到满足；其中，预定的条件包括：该数据包的重复传输的次数达到K次；和在该时域周期内的第N个TO传输了该数据包的一次重复，其中，N为大于K的整数。
第三方面，本申请提供了一种通信装置，该通信装置包括用于执行第一方面或第二方面中的传输方法的模块。该通信装置包括的模块可以通过软件和/或硬件方式实现。
在一种可能的实现方式中，该通信装置可以包括处理器和发送器。
其中，处理器用于确定时域周期内用于数据包初传的TO；发送器用于：从用于数据包初传的TO开始，在时域周期内的TO传输数据包的重复，直到数据包的重复传输的次数达到K次和在时域周期内的第N个TO传输了数据包的一次重复中的任意一个条件得到满足，终止数据包的重复传输，其中，K为配置的重复传输的最大次数，N为大于K的整数。
或者，处理器用于确定时域周期内用于数据包初传的TO；发送器用于：从所述用于数据包初传的TO开始，在时域周期内的TO传输数据包的重复；处理器还用于在时域周期内的第K个TO内传输了数据包的一次重复之后，判断数据包的重复传输的是否达到K次，其中，K为配置的重复传输的最大次数；如果数据包的重复传输的次数未达到K次，发送器还用于在时域周期内剩余的TO继续传输数据包的重复，直到预定的条件中任意一个得到满足；其中，预定的条件包括：数据包的重复传输的次数达到K次；和在时域周期内的第N个TO传输了数据包的一次重复，其中，N为大于K的整数。
可选地，该通信装置还可以包括存储器。存储器用于存储程序和数据。
可选地，该通信装置还可以包括接收器。接收器用于接收信息。
例如，该通信装置可以是终端设备。
在一种可能的实现方式中，该通信装置可以是芯片，该芯片包括输出接口、至少一个处理器和总线。
该至少一个处理器用于确定时域周期内用于数据包初传的TO；该输出接口用于从用于数据包初传的TO开始，在时域周期内的TO传输数据包的重复，直到数据包的重复传输的次数达到K次和在时域周期内的第N个TO传输了数据包的一次重复中的任意一个条件得到满足，终止数据包的重复传输，其中，K为配置的重复传输的最大次数，N为大于K的整数。
或者，该至少一个处理器用于确定时域周期内用于数据包初传的TO；该输出接口用于从所述用于数据包初传的TO开始，在时域周期内的TO传输数据包的重复；处理器还用于在时域周期内的第K个TO内传输了数据包的一次重复之后，判断数据包的重复传输的次数是否达到K次，其中，K为配置的重复传输的最大次数；如果数据包的重复传输的次数未达到K次，发送器还用于在时域周期内剩余的TO继续传输数据包的重复，直到预 定的条件中任意一个得到满足；其中，预定的条件包括：数据包的重复传输的次数达到K次；和在时域周期内的第N个TO传输了数据包的一次重复，其中，N为大于K的整数。
该芯片还可以包括输入接口，该输入接口用于接收信息。
该芯片还可以包括至少一个存储器，该至少一个存储器用于存储程序代码和数据。
第四方面，本申请提供了一种计算机可读存储介质。该计算机可读存储介质中存储用于通信装置执行的程序代码。该程序代码包括用于执行第一方面或第二方面中的传输方法的指令。
第五方面，本申请提供了一种包含指令的计算机程序产品。当该计算机程序产品在通信装置上运行时，使得该通信装置执行第一方面或第二方面中的传输方法。
上述各个方面的传输方法、通信装置、计算机可读存储介质、计算机程序产品和系统芯片中，由于终止重复传输数据包的条件为数据包的重复传输次数等于K和在第K个TO后的TO传输了数据包，使得数据包在第K个TO重复传输后，若传输次数没有达到K次，数据包还能继续在第K个TO之后的TO进行重复传输。
这与数据包在第K个TO上传输后，不管数据包的传输次数有没有达到K次，都必须终止数据包的重复传输相比，有助于增加数据包的重复传输次数，进而有助于提高数据包的传输可靠性。
在一种可能的实现方式中，第N个TO为时域周期内可用于重复传输的最后一个TO。
也就是说，在第K个TO传输数据包的一次重复后，若数据包的重复传输次数没有达到K次，就会继续在该时域周期中确定TO，并在确定出的TO继续传输该数据包的重复，直到数据包的重复传输次数达到K次或在该时域周期内可用于重复传输的最后一个TO传输数据包的最后一次重复。
在一种可能的实现方式中，时域周期内用于数据包初传的TO是在时域周期内的前M个TO中的TO中确定的，其中，M整数，且K≤M＜N。在该实现方式中，如果时域周期加大时，那么周期内第M+K-1个TO就可以被分配用于基于授权的数据传输，也可以被分配给其它的通信设备用于数据传输，从而提高了资源利用率。在一种可能的实现方式中，N等于M+K-1。或者说，M与N和K之间可以满足如下关系：N＝M+K-1。
在一种实现方式中，若M＝K，则N＝2*K-1。这使得即使初传数据包的TO为第K个TO，该数据包的重传次数也能达到K次。
在一种可能的实现方式中，在第K个TO之后的TO传输数据包时，传输数据包所使用的冗余版本是由TO所关联的冗余版本的版本号确定的。

具体实施方式
下面将结合附图，以通信装置是终端设备为例，对本申请中的技术方案进行描述。
图1是应用本申请实施例的传输方法的通信系统的示意性架构图。应理解，本申请实施例并不限于图1所示的系统架构中，此外，图1中的装置可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。
图1所示的通信系统中可以包括接入网设备110和终端设备120。接入网设备110的一种示例为基站。
应理解，本申请实施例对基站的具体类型不作限定。采用不同无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为基站。
基站(base station，BS)，也可称为基站设备，是一种将终端接入到无线网络的设备，包括但不限于：传输接收点(transmission reception point，TRP)、5G节点B(gNB)、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Wifi接入点(access point，AP)，或小基站设备(pico)等。
终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网(core network，CN)进行通信。终端设备可称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线网络设备、用户代理或用户装置。终端设备可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它设备、车载设备、可穿戴设备或物联网、车辆网中的终端以及未来网络中的任意形态的终端等。
图1所示的通信系统中，接入网设备110可以预先为终端设备120分配用于免授权传输的传输资源和/或传输参数；然后，终端设备120需要向接入网设备110发送数据包时，可以直接使用接入网设备110分配的传输资源和/或参数向接入网设备110发送数据包，而不用向接入网设备110发送调度请求并等待接入网设备110为终端设备120分配授权资源。
例如，接入网设备110可以预先为终端设备120配置进行免授权传输所使用的如下传输资源和/或传输参数包括：周期(periodicity，P)、时域资源的偏置参数(offset)、时域资源分配参数(time domain resource allocation)、重复次数K(number of repetitions K)和冗余版本(redundancy version)序列等。
这些传输资源和传输参数可以由接入网设备110通过无线资源控制(radio resource  control，RRC)信令、下行控制信息(downlink control information，DCI)和/或媒体接入控制(media access control，MAC)层控制单元(control element，CE)发送给终端设备120。
终端设备120需要向接入网设备110发送数据包时，可以直接根据上述传输资源和传输参数，确定出用于免授权传输的传输资源和/或传输参数，并使用该传输资源和/或传输参数向接入网设备110发送数据包，从而实现免授权上行传输。
接入网设备110为终端设备120分配的免授权资源的一种示例如图2所示。图2中，周期P包括8个时隙(slot)，一个时隙中包括一个TO，重复传输次数K为4。由图2可知，接入网设备110给终端设备120分配了4个TO。一个TO为用于数据包的一次上行传输的时域资源。
终端设备120使用图2所示的免授权资源传输数据包的一种方法可以包括：终端设备120在这4个TO中确定初次传输数据包的TO，初次传输数据包的TO可以称为首次TO；终端设备从首次TO开始进行数据包的重复传输，直到数据包的重复传输次数等于K次或在第4个TO上完成数据包的重复传输，终端设备在该周期内终止该数据包的重复传输。
例如，终端设备120将第3个TO确定为数据包的首次TO，然后终端设备120在第3个TO和第4个TO上传输数据包。也就是说，数据包的传输次数实际上为两次。
由此看出，上述使用免授权资源重复传输数据包的方法中，数据包的首次TO不是第一个TO时，数据包的重复传输次数会较少，从而会影响数据包的传输可靠性。
因此，本申请提出了一种数据包的传输方法，该传输方法有助于提高数据包的传输可靠性。
本申请一个实施例的传输方法的示意性流程图如图3所示。图3所示的传输方法包括S310、S320和S330。图3所示的传输方法由通信装置执行。通信装置的一种示例为图1中的终端设备120。
应理解，图3示出了传输方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图3中的各个操作的变形。
S310，确定时域周期内用于数据包初传的TO。
其中，数据包可以是传输块(transmission block，TB)，也可以是码块(coded block，CB)，可以是码块组(coded block group，CBG)。
例如，根据配置的RV序列确定时域周期内用于数据包初传的TO：
当配置的RV序列为{0231}时，在时域周期内的第一个TO上开始数据包的重复传输；
当配置的RV序列为{0303}时，只能在时域周期内RV0所关联的TO上开始数据包的重复传输；
当配置的RV序列为{0000}时，若K＝8，终端设备只能在时域周期内前M个TO中除最后一个TO外的其他TO上开始数据包的重复传输；若K＝1，2，4，终端设备可以在时域周期内前M个TO上的中任意一个TO开始数据包的重复传输。
在一种可能的设计中，终端设备准备好待发送的数据包后，可以将时间上最近的TO确定为用于该数据包初传的TO。
在一种可能的设计中，终端设备准备好待发送的数据包后，可以将下一个时域周期内的第一个TO确定为用于该数据包初传的TO。
S320，从用于数据包初传的TO开始，在时域周期内的TO传输数据包。其中，用于数据包初传的TO可以称为数据包的首次TO。
确定数据包的首次TO之后，在该首次TO以及该时域周期内位于首次TO后的TO依次传输数据包。
例如，终端设备可以从该时域周期内的首个slot开始，根据时域资源分配参数，依次在每个slot中确定出用于该数据包的重复的时域资源，该时域资源即为用于该数据包的重复的TO。其中，该时域资源分配参数用于指示一个slot中用于数据包的重复的时域资源的位置。
例如，时域周期包括8个slot、时域资源分配参数指示一个TO占用一个slot中的第5个和第6个符号时，终端设备可以从该时域周期内的第一个slot开始确定TO。其中，该时域周期内的第一个TO包括该时域周期内的第一个slot中的第5个和第6个符号，第二个TO包括第二个slot中的第5个符号和第6个符号，依次类推，可以确定出该时域周期内的所有TO。
例如，终端设备可以从该时域周期内的首个符号开始，根据时域资源分配参数，依次在该时域周期内确定出用于该数据包的重复的时域资源，该时域资源即为用于该数据包的重复的TO。其中，该时域资源分配参数用于指示一个TO所占的符号数。
例如，时域周期包括28个符号、时域资源分配参数指示一个TO占用两个符号时，终端设备可以从时域周期中的第一个符号开始确定TO。其中，该时域周期内的第一个TO包括该时域周期内的第一个符号和第二个符号，第二个TO包括第三个符号和第四个符号，依次类推，可以确定出该时域周期内的所有TO。
S330，在数据包的重复传输的次数等于K次和在时域周期的第N个TO传输数据包的一次重复传输中的任意一个条件得到满足时，终止数据包的重复传输，K为配置的重复传输的最大次数，N为大于K的整数。
在本申请中，重复传输中的首次传输(或者称之为初始传输)也被称之为一次重复传输，重复传输的次数包含首次传输。
本申请另一个实施例的传输方法的示意性流程图如图4所示。图4所示的传输方法包括S410、S420、S430和S440。图4所示的传输方法由数据包的传输装置执行。传输装置的一种示例为图1中的终端设备120。
应理解，图4示出了传输方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图4中的各个操作的变形。
S410，确定时域周期内用于数据包初传的TO。其中，数据包也可以称为TB。
S420，从用于数据包初传的TO开始，在时域周期内的TO传输数据包的重复。
S430，在时域周期内的第K个TO内传输了数据包的一次重复之后，判断所述数据包的重复传输的次数是否达到K次，其中，K为配置的重复传输的最大次数。
S440，如果数据包的重复传输的次数未达到K次，在时域周期内剩余的TO继续传输数据包的重复，直到预定的条件中任意一个得到满足，其中，预定的条件包括：数据包的重复传输的次数达到K次，和在时域周期内的第N个TO传输了数据包的一次重复，N为大于K的整数。
图3和图4所示的传输方法中，时域周期即为前面提到的周期P，例如可以是接入网 设备110为终端设备120分配的免授权资源所包括的传输参数中的周期P；TO是指用于数据包的一次上行传输所使用的时域资源。
由N为大于K的整数可知，该第N个TO应位于第K个TO之后。
也就是说，该时域周期内，在第K个TO之后，应存在可用于数据包的重复传输的免授权资源。或者说，传输装置在该时域周期内第K个TO之后的时域资源中，能够确定出第N个TO。
图3和图4所示的传输方法中，在第K个TO上传输了数据包的一次重复之后，如果数据包的传输次数没有达到K次，则传输装置还可以在该时域周期内继续传输数据包的重复，从而可以增加数据包的重复传输次数，进而有助于提高数据包的传输可靠性。
可选地，第N个TO可以是时域周期内能够配置的或可用于重复传输的最后一个TO。换句话说，第N个TO可以是时域周期内最多能够配置的TO中的最后一个TO，或者可用于重复传输的最后一个TO。或者说，传输装置在第N个TO上传输数据包的一次重复后，该时域传输周期内没有可用资源能够确定出TO，以传输数据包其他次重复。
在一种实现方式中，传输装置在第K个TO上进行数据包的重复传输后，若数据包的重复传输次数没有达到K次，则传输装置可以继续在该第K个TO所在的周期内的可用的资源中确定TO，并在确定出的TO上重复传输数据包；传输装置重复该步骤，直到数据包的重复传输次数达到K次或者直到该周期内没有可用的资源能够确定出TO，传输装置在该周期内终止该数据包的重复传输。
在另一种实现方式中，传输装置在第K个TO上进行数据包的重复传输后，若数据包的重复传输次数没有达到K次，则传输装置在第K个TO所在时域周期内的剩余的TO内继续传输该数据包的重复，直到任意一个预定的条件得到满足；其中，预定的条件包括数据包的重复传输次数达到K次，和传输装置在该时域周期内的第N个TO传输了该数据包的最后一次重复。
时域周期内最多能够配置的或可用于重复传输的TO的数量可以是协议规定的，也可以由终端设备和接入网设备预先约定，也可以由接入网设备通过高层信令和/或底层信令下发给终端设备，也可以由终端设备根据时域周期以及时域资源分配参数确定。
高层信令的一种示例为RRC信令，底层信令的示例包括DCI和MAC CE。
本申请实施例的传输方法中，一个周期内最多能够配置的或可用于重复传输的TO的数量X可以满足如下关系：K<X<＝floor(P/T)，P表示时域周期，T表示一个TO占用的时域资源大小。一个TO占用的时域符号数可以根据接入网设备下发的时域资源分配参数确定。
时域周期内TO的一种配置方法包括：从时域周期内的首个符号开始，连续配置TO；或者从时域周期内的首个时隙开始，在连续的时隙配置TO，其中，每个时隙上至多配置一个TO。
例如，一个时隙内至多只能配置一个TO，T为一个slot时，若P内包括8个slot，则该P内最多能够配置的TO为8个。
例如，一个时隙内允许配置多个TO，T为2个时域符号数时，若P内包括2个slot，则该P内最多能够配置的TO为14个。
本申请实施例的传输方法中，可选地，确定时域周期内用于数据包初传的TO，可以 包括：在时域周期内的前M个TO中确定用于数据包初传的TO，其中，M整数，且K≤M＜N。
换句话说，时域周期内用于数据包初传的TO可以是时域周期内的前K个TO中的TO；或者可以是第K个TO后的TO，且为第M个TO前的TO。
这种实现方式中，由于在第K个TO后还能进行数据包的初传，从而有助于降低数据包的等待时延。
例如，当为终端设备配置的RV序列为{0 2 3 1}时，终端设备在时域周期内的第一个TO上开始数据包的重复传输。
例如，当为终端设备配置的RV序列为{0 3 0 3}时，终端设备在时域周期内RV0所关联的TO上开始数据包的重复传输。
例如，当为终端设备配置的RV序列为{0 0 0 0}时，且M＝8时，终端设备在时域周期内前M个TO中除最后一个TO外的其他TO上开始数据包的重复传输。
例如，当终端设备上配置的RV序列为{0 0 0 0}时，且M＝1，2，4时，终端设备在时域周期内前M个TO上的中任意一个TO开始数据包的重复传输。
本申请实施例的传输方法中，可选地，N可以等于M+K-1。也就是说，用于数据包初传的TO为时域周期内前M个TO中的TO时，第N个TO可以为时域周期内的第M+K-1个TO。
从另一个角度来说，用于数据包初传的TO可以是时域周期内前N+1-K个TO中的TO。
这种传输方法使得数据包从前M个TO中的任意一个TO开始初传时，数据包的传输次数都可以达到K次，从而有助于提高数据包的传输可靠性。
本申请实施例的传输方法中，在第K个TO之后的TO重复传输数据包，即在第K+1个TO至第N个TO重复传输数据包时，传输数据包所使用的冗余版本可以是由传输该数据包的TO所关联的冗余版本的版本号确定的。
其中，传输该数据包的TO所关联的冗余版本的版本号可以根据该TO在时域周期内的索引以及终端设备上配置的RV序列来确定。
例如，第S个TO关联的冗余版本的RV号为RV序列中的第(mod(S-1,4)+1)个元素的值，其中，K<S<＝N，mod(A,B)表示A对B取模操作。需要说明的是，时域周期内的第1个TO到第K个TO所关联的TO也同样适用次方法确定。
下面以传输装置为终端设备，一个slot中最多配置一个TO，K为4，RV序列为{0 0 00}、M＝K＝4为例，结合图5至图8，介绍本申请实施例的传输方法。
图5中，时域周期为8个slot，N＝6。
若终端设备从时域传输周期内前4个TO中的第2个TO开始数据包的重复传输，则终端设备在第5个TO传输数据包后，由于数据包的重复传输次数达到4次，因此终端设备终止该数据包的重复传输。
若终端设备从时域传输周期内前4个TO中的第3个TO开始数据包的重复传输，则终端设备在第6个TO传输数据包后，由于数据包的重复传输次数达到4次，因此终端设备终止数据包的重复传输。这种情况下，终端设备刚好在第6个TO传输数据包后终止数据包的重复传输。
若终端设备从时域传输周期内前4个TO中的第4个TO开始数据包的重复传输，则终端设备在第6个TO传输数据包后，由于N＝6，因此终端设备终止数据包的重复传输。
图6中，时域周期为6个slot，第N个TO为时域周期内能够配置的最后一个TO。
若终端设备从时域传输周期内前4个TO中的第2个TO开始数据包的重复传输，则终端设备在第5个TO传输数据包后，由于数据包的重复传输次数达到4次，因此终端设备终止该数据包的重复传输。
若终端设备从时域传输周期内前4个TO中的第3个TO开始数据包的重复传输，则终端设备在第6个TO传输数据包后，由于数据包的重复传输次数达到4次，因此终端设备终止数据包的重复传输。这种情况下，终端设备刚好在该时域周期内能够配置的最后一个TO传输数据包后终止数据包的重复传输。
若终端设备从时域传输周期内前4个TO中的第4个TO开始数据包的重复传输，则终端设备在第6个TO传输数据包后，虽然数据包的重复传输次数没有达到4次，但是由于该时域周期内没有资源可以用于配置TO，即终端设备已在该时域周期内能够配置的最后一个TO传输数据包，因此终端设备仍然终止数据包的重复传输。
图7中，时域周期为8个slot，N＝7。这种情况下，由于N＝M+K-1，因此，即使终端设备在时域周期内前4个TO中的第4个TO开始数据包的重复传输，也能使得数据包的传输次数能够达到K＝4次。
图8中，时域周期为8个slot，与图7同样的原理，即使终端设备在时域周期内前4个TO中的第4个TO开始数据包的重复传输，也能使得数据包的传输次数能够达到K＝4次，其终止于时域周期内的第7个TO(即指定的TO)，而不是时域周期内的第8个TO。
