Description

数据传输方法、终端设备及接入网设备

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、终端设备及接入网设备。
背景技术
混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)使用停等协议(stop-and-wait protocol)来发送数据。在停等协议中，发送端发送一个传输块(Transport Block，TB)后，就停下来等待确认信息。接收端针对该TB向发送端发送反馈消息，以反馈自己是否接收到该TB。但是每次传输后发送端就停下来等待反馈消息，从而导致通信系统吞吐量较低的问题。因此长期演进(Long Term Evolutiong，LTE)使用多个并行进程来发送数据。当一个进程在等待反馈消息时，发送端可以使用另一个进程继续发送数据。
目前，接入网设备向终端设备配置的进程数目都是固定的配置的。比如：针对频分双工(Frequency Division Duplexing，FDD)模式，接入网设备向终端设备配置的进程数目为8。然而在5代(Generation，G)网络或者新一代无线接入技术(New Radio Access Technology，NR)中，进程数目可能会被许多因素所影响，因此现有技术存在进程数目的配置方式不够准确、不够高效的问题。

另外，本发明实施例中涉及的终端设备可以是指向用户提供语音和/或数据连通性的 设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其它处理设备。该终端设备可以经无线接入网(Radio Access Network，RAN)与至少一个核心网进行通信。该终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和带有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。终端设备也可以称为用户单元(Subscriber Unit)、用户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile Station)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)或用户设备(User Equipment)，在此不作限定。
为了解决在5G或者NR网络中，进程数目可能会被许多因素所影响，因此现有技术存在进程数目的配置方式不够准确、不够高效等问题。本申请提供一种数据传输方法及装置。
本申请中终端设备可以开启多个进程，以实现数据传输。本申请提供一种数据传输方法，其中终端设备或者接入网设备可以根据终端设备对应的每个载波的信息确定进程数目，从而使得终端设备可以根据该进程数目进行数据传输。
具体地，图1为本申请提供的数据传输方法的应用场景示意图，如图1所示，本申请中一个接入网设备可以与多个终端设备进行数据传输。本申请主要介绍一个接入网设备和一个终端设备之间的数据传输。
具体地，图2为本申请一实施例提供的数据传输方法的流程图。如图2所示，该方法包括如下流程：
步骤S201：终端设备接收接入网设备发送的终端设备对应的载波的信息。
所谓终端设备对应的载波为终端设备的传输载波。接入网设备可以为终端设备同时配置至少一个载波。其中，针对每个载波：其中，当数据为上行数据时，载波的信息可以包括以下至少一项：终端设备在载波上的上行调度和上行调度对应的上行数据传输的时间关系；所述终端设备在载波上的时间调度单元信息；终端设备在载波上的子载波间隔；终端设备在载波上的传输能力信息。
当数据为下行数据时，载波的信息可以包括以下至少一项：终端设备在载波上的下行调度和下行调度对应的下行数据传输的时间关系；终端设备在载波上的下行数据传输和终端设备接收到下行数据之后发送的反馈消息的时间关系；终端设备在载波上的时间调度单元信息；终端设备在载波上的子载波间隔；终端设备在载波上的传输能力信息。
其中本申请中的时间关系等价于时间间隔。例如：当上行调度或者控制指示(Downlink Control Indication，DCI)或者控制消息或者控制信道在时间调度单元n上进行时，并且对应的上行数据传输在时间调度单元n+k上进行时，它们之间的时间间隔为k。需要说明的是，本申请所涉及到的时间调度单元或时间单位可为一个或多个时隙slot，或者一个或多个小-时隙mini-slot，或者传输时间间隔(Transmission Time Interval，TTI)，或者一个或多个时域符号数或者子帧等。下面不再赘述。另外两种时间关系定义类似，不再赘述。
载波上的时间调度单元信息可以是一个时间调度单元包括的时隙slot的个数，或者包括的小-时隙mini-slot的个数，TTI，或者包括的时域符号数或者包括的子帧个数或者绝对 时长(比如1毫秒(millisecond，ms)，0.5ms等)或者采样点数等。
终端设备在载波上的传输能力信息可以包括：终端设备在载波上的最大传输功率、终端设备在载波上的传输模式等。该传输模式具体可以是：终端设备可以和其他终端设备复用载波进行数据传输，或者是终端设备单独在载波上进行数据传输等。
此外，载波的信息可以包括：载波的间隙聚合类型和/或终端设备在载波上的待处理业务的类型。其中间隙聚合类型表示一次可以聚合多少个间隙，并且进程或者TB与聚合后的间隙的对应关系。比如：一次可以聚合10个间隙，其中这10个间隙与1个TB对应。
终端设备在载波上的待处理业务的类型可以是超高可靠低时延通信(Ultra-Reliable Low Latency Communication，URLLC)类型或者是增强移动宽带通信(Enhanced Mobile BroadBand，eMBB)类型等。本申请实施例对此不做限制。
步骤S202：终端设备根据载波的信息确定载波对应的进程数目。
其中当终端设备发送的数据为下行数据时，载波对应的进程数目为用于传输下行数据的进程的数目。当终端设备发送的数据为上行数据时，载波对应的进程数目为用于传输上行数据的进程的数目。
示例一：当终端设备发送的数据为上行数据，且载波的信息为在载波上的上行调度和该上行调度对应的上行数据传输的时间关系时，终端设备可以根据该时间关系确定载波对应的进程数目。其中接入网设备可以针对每个载波配置一个时间关系集合或者针对所有载波统一配置一个时间关系集合，该时间关系集合包括：至少一个在该载波上的上行调度和上行数据传输的时间关系。终端设备可以在该集合中选择其中一个时间关系，比如选择所述集合中的最大值，根据该最大值确定该载波对应的进程数目。
一种可选方式，图3为本申请一实施例提供的确定进程数目的方法流程图，如图3所示，该方法包括如下步骤：
步骤S301：终端设备确定上行调度和该上行调度对应的上行数据传输的时间间隔。
步骤S302：终端设备确定时间间隔与常数M之和为载波对应的进程数目。
具体地，假设接入网设备为某载波配置的上行调度和该上行调度对应的上行数据传输的时间关系为一个集合，假设该集合为{2，4}，该集合中的每个元素表示该载波上的上行调度和上行数据传输的可能的时间间隔。终端设备在该集合中选择最大值4。常数M可选地为接入网设备处理上行数据的时长或其它数值。假设M为4，则M与最大值4之和为8。终端设备确定载波对应的进程数目为8。
其中，步骤S302也可以是终端设备确定集合中某个值与常数N之积作为载波对应的进程数目。
另一种可选方式，图4为本申请另一实施例提供的确定进程数目的方法流程图，如图3所示，该方法包括如下步骤：
步骤S401：终端设备确定载波对应的默认进程数目，并确定默认进程数目对应的上行调度和上行数据传输的第一时间间隔。
步骤S402：终端设备根据默认进程数目和第一时间间隔确定时间间隔和进程数目的映射关系；
步骤S403：终端设备确定在载波上的上行调度和在载波上的上行数据传输的第二时 间间隔；
步骤S404：终端设备根据映射关系和第二时间间隔确定载波对应的进程数目。
具体地，所谓默认进程数目对应的上行调度和上行数据传输是指默认进程数目对应上行调度，该上行调度对应该上行数据传输。另外，本申请涉及的：载波上的上行调度和在载波上的上行数据传输表示该上行数据传输为该载波上的上行调度对应的上行数据传输。假设终端设备确定某载波对应的默认进程为p0。默认进程对应的第一时间间隔为t0。第二时间间隔为t1，则载波对应的进程数目p1为p1＝p0+f(t1-t0)，其中第二时间间隔也是终端设备在上述的时间关系集合中选择的一个值。该公式即为上述的时间间隔和进程数目的映射关系。例如：某载波对应的默认进程为10，f(t1-t0)＝t1-t0。t1＝16，t0＝10，则p1＝10+16-10＝16。其中时间间隔和进程数目的映射关系是根据时间间隔和进程数目之间的规律确定的，因此本申请对时间间隔和进程数目的映射关系不做限制。
示例二，当载波的信息包括在载波上配置的时间调度单元信息时，终端设备可以根据该载波上的时间调度单元信息确定载波对应的进程数目。具体地，终端设备获取到在载波上配置的时间调度单元信息后，根据时间调度单元信息与进程数目的对应关系确定载波对应的进程数目。假设时间调度单元信息为时间调度单元包括的时域符号数，则时间调度单元包括的时域符号数与进程数目的对应关系可选地见表一。可选地，载波的进程数目与时间调度单元包括的时域符号数呈反比。作为示例但不限定见表一

示例三，当载波的信息包括：在载波上配置的子载波间隔时，终端设备可以根据该子载波间隔确定载波对应的进程数目。具体地，终端设备获取到在载波上配置的子载波间隔后，根据子载波间隔与进程数目的对应关系确定载波对应的进程数目。可选地，进程数目与子载波间隔呈正比。作为示例但不限定见表二

可选地，表二所示的载波的子载波间隔与进程数目的对应关系可以是协议预先确定的或者通过RRC配置或者通过MIB消息、SIB消息、MAC CE信令配置。
示例四：当载波的信息包括载波的间隙聚合类型时，终端设备可以根据该间隙聚合类型确定载波对应的进程数目。图5为本申请一实施例提供的间隙聚合示意图，如图5所示，左侧的间隙聚合方式是：接入网设备通过1个下行控制指示(Downlink Control Indication，DCI)在某载波调度N个间隙，N为大于1的正整数。其中这些间隙与1个进程或者1个TB对应。基于此，终端设备确定该载波对应的进程数目为8。右侧的间隙聚合方式是：接入网设备通过1个DCI在某载波调度N个间隙，其中间隙与进程一一对应，或者间隙与TB一一对应。基于此，终端设备确定该载波对应的进程数目为16。其中载波的间隙聚合类型与载波对应的进程数目的对应关系不是唯一的，本申请对此不做限制。
示例五：当载波的信息为终端设备在载波上的传输能力信息时，终端设备可以根据该终端设备在载波上的传输能力信息确定载波对应的进程数目。假设终端设备在某载波上的传输能力信息为终端设备在该载波上的最大传输功率，则最大传输功率与载波对应的进程数目成正比。假设终端设备在某载波上的传输能力信息为终端设备在某载波上的传输模式。该传输模式具体可以是：终端设备可以和其他终端设备复用载波进行数据传输，或者是终端设备单独在载波上进行数据传输等。其中当终端设备和其他终端设备复用载波进行数据传输时，终端设备确定的进程数目大于终端设备单独在载波上进行数据传输所确定的进程数目。
示例六：当载波的信息包括终端设备在载波上的待处理业务的类型时，终端设备可以根据该待处理业务的类型确定载波对应的进程数目。例如：终端设备在载波上的待处理业务的类型与载波对应的进程数目的对应关系如表三：
表三：

URLLC业务 1
eMBB业务 8
示例七：当终端设备发送的数据为下行数据，且载波的信息包括：在载波上的下行调度和该下行调度对应的下行数据传输的时间关系时，终端设备可以根据该时间关系确定载波对应的进程数目。其中接入网设备可以针对载波配置一个时间关系集合，该时间关系集合包括：至少一个在载波上的下行调度和下行数据传输的时间关系。终端设备可以在该时间关系集合中选择一个时间关系，比如最大值，以确定该载波对应的进程数目。
假设接入网设备为某载波配置的下行调度和下行数据传输的时间关系为一个时间关系集合，假设该集合为{2，4}，该集合中的每个元素表示该载波上的下行调度和下行数据传输的可能的时间间隔，终端设备在该集合中选择一个最大值4。假设M为4，则4与该最大值4的和为8。终端设备确定载波对应的进程数目为8。
以上例子也可以是终端设备确定时间关系集合中某个值与常数N之积作为载波对应的进程数目。
示例八：当终端设备发送的数据为下行数据，且载波的信息包括在载波上的下行数据 传输和终端设备接收到该下行数据之后发送反馈消息的时间关系时，终端设备可以根据该时间关系确定载波对应的进程数目。其中接入网设备可以针对载波配置一个时间关系集合，该时间关系集合包括：至少一个在载波上的下行数据传输和终端设备发送所述下行数据的反馈消息的时间关系。终端设备可以在该时间关系集合中选择一个时间关系，比如最大值，以确定该载波对应的进程数目。
