一种数据传输方法、装置及设备
相关申请的交叉引用
本公开要求在2020年10月23日提交中国专利局、申请号为202011149169.5、名称为“一种数据传输方法、装置及设备”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及移动通信技术领域，尤其涉及一种数据传输方法、装置及设备。
背景技术
在现在的传输机制中，数据包在媒体接入控制(Medium Access Control，MAC)层递交给物理层后，基于配置授权资源向网络设备发送，在部分传输后，可能会发生该数据包停止发送的情况。在该数据包停止发送后，用户设备(User Equipment，UE)在MAC层会打开配置授权定时器(Configured Grant Timer，CGT)和/或配置授权重传定时器(CG-Retransmission Timer，CGRT)。
如果网络设备成功接收该数据包，那么在NR非授权频谱(NR-unlicensed spectrum，NR-U)场景中，网络侧会反馈下行反馈信息(Downlink Feedback Information，DFI)，即指示成功接收到数据；如果网络设备不能成功接收，在工业物联网(Industrial Internet of Things，IIoT)场景中，网络侧会向UE发送重传调度。但是由于信道等原因，UE无法接收到网络侧的DFI或是重传调度，导致UE需要在定时器超时后，才能执行数据的传输。这样会增加传输延时，特别是当业务是IIoT业务时，延时的增加会严重影响业务的性能。

本公开实施例涉及的终端设备，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他处理设备等。在不同的系统中，用户设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备。无线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，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，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言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装 置(user device)，本公开实施例中并不限定。

网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output，MIMO)传输，MIMO传输可以是单用户MIMO(Single User MIMO，SU-MIMO)或多用户MIMO(Multiple User MIMO，MU-MIMO)。根据根天线组合的形态和数量，MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO，也可以是分集传输或预编码传输或波束赋形传输等。
首先对现有传输机制进行阐述。针对配置授权(Configured Grant，CG)而言，与动态调度时每个时隙/传输时间间隔(Transmission Timing Interval，TTI)为UE分配一次无线资源不同(通过物理下行控制信道(Physical downlink control channel，PDCCH)指定)，配置授权允许半静态配置无线资源，并将该资源周期性地分配给某个特定UE。简单地说，网络侧通知UE可以周期性 地使用某一个资源，可以通过无线资源控制(Radio Resource Control，RRC)信令通知周期性资源的位置。网络侧还可以通知UE使用资源的频域位置，起止时间，调制编码方式(Modulation Coding Scheme，MCS)等信息。这样，网络侧通过周期性的资源分配，减少了PDCCH通知开销。
配置授权调度方式，适用于周期性业务，比如，网络电话(Voice Over IP，VoIP)，某些超可靠低时延通信(Ultra Reliable Low Latency Communications，URLLC)业务中具有周期性的控制信令等业务。配置授权是一种上行调度方式，存在type1和type2两种方式。
在Type1中：RRC分配周期资源，并在RRC配置后，资源即处于激活状态，即UE在收到RRC配置消息后，即可以使用该资源发送上行数据；
在Type2中，RRC分配周期资源，但是初始状态是非激活的，网络侧需要通过物理层信令来激活该资源，在数据传输结束后，通过下行控制信息(Downlink Control Information，DCI)来去激活资源。同样的，也可以通过物理层信令来修改部分配置授权的配置信息，比如修改资源的时频域位置信息等。
针对CGT而言，在新无线(New Radio，NR)中，上行链路(UpLink，UL)数据发送没有下行链路(Downlink，DL)反馈。如果UL传输失败，网络侧通过PDCCH发送重传调度命令，如果UL数据传输成功，网络侧如果反馈PDCCH，那么就无法达到节省PDCCH开销的目的，所以定义了一个CGT，该定时器在UE发送数据包后打开。如果在CGT超时之前，UE收到了该混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程的重传调度，那么UE将执行重传操作。如果UE没有收到网络侧的重传调度，那么UE将在CGT超时后，认为数据传输成功。
针对CGRT而言，在NR-U中引入了CGRT，这是因为，在NR-U中，HARQ进程身份标识号(Identity Document，ID)是UE自主选择的，当网络侧无法接收到UE的数据包时，则无法执行重传调度，所以在NR-U引入的机制是网络侧向UE发送反馈信令DFI。但是由于NR-U信道是抢占式的，那么UE可能会无法接收到DFI，所以引入CGRT。该定时器在UE发送数据包后打开。当此定时器没有超时，UE收到DFI(正确反馈)，那么UE将停止该定时器，如果该定时器超时后仍然无法接收的DFI，那么UE将执行重传操作。
在现有传输机制中，当UE的数据包在MAC层递交给物理层，物理层在发送该数据包时，可能会出现打断当前协议数据单元(Protocol Data Unit，PDU)发送的情况，例如，发生数据发送抢占preemption。
例如，参见图1所示，数据包A从MAC层递交到了物理层，开启定时器CGT/CGRT，但是在物理层发生了preemption，即物理层优先发送较高优先级的数据B。而由于信道等原因，UE没有接收到网络侧发送的针对数据包A的DFI，导致UE只能在定时器CGRT超时后，才能重传数据包A，这样增加了数据传输的时延。
由此可见，现有的传输机制存在增加传输延时影响业务性能的问题。为了解决现有传输机制存在的问题，本公开实施例提供一种数据传输方法、装置及设备。
图2示出了本公开实施例提供的一种数据传输方法的流程示意图，该方法应用于用户设备，其中用户设备包括用户设备MAC层以及用户设备物理层，该方法包括：
步骤201、用户设备媒体接入控制MAC层向用户设备物理层递交第一数据包，并启动配置授权定时器CGT和/或配置授权重传定时器CGRT。
用户设备MAC层首先向用户设备物理层递交第一数据包，以使得用户设备物理层将接收到的第一数据包发送至网络设备。用户设备MAC层在将第一数据包递交至用户设备物理层之后，可以启动CGT和/或CGRT。
步骤202、所述用户设备MAC层确定所述第一数据包在所述用户设备物理层停止发送的情况下，停止所述CGT和/或所述CGRT，并在所述CGT和/或所述CGRT停止后发送所述第一数据包。
用户设备MAC层在将第一数据包递交至用户设备物理层之后，若确定第一数据包在用户设备物理层停止发送，则可以停止CGT和/或CGRT。具体为：若之前发送第一数据包后启动了CGT则此时停止CGT，若之前发送第一数据包后启动了CGRT则此时停止CGRT，若之前发送第一数据包后启动了CGRT和CGT，则此时停止CGRT和CGT。在停止CGT和/或CGRT之后，用户设备MAC层可以发送第一数据包。通过停止CGT和/或CGRT并在CGT和/或CGRT停止后发送第一数据包，可以避免在定时器超时后执行数据传输动作，保证用户设备提前完成数据的传输，节省时延。
本公开实施例中，在用户设备MAC层向用户设备物理层递交第一数据包并启动CGT和/或CGRT之后，在确定第一数据包在用户设备物理层停止发送的情况下，停止CGT和/或CGRT并在CGT和/或CGRT停止后发送第一数据包，可以避免在定时器超时后执行数据传输动作，保证用户设备提前完成数据的传输，节省时延。
在本公开一可选实施例中，该方法还包括：
所述用户设备物理层在发送所述第一数据包时检测到目标场景的情况下，停止发送所述第一数据包，并向所述用户设备MAC层反馈通知信息；
其中，所述用户设备MAC层根据所述通知信息确定所述第一数据包停止发送。
在用户设备MAC层向用户设备物理层递交第一数据包之后，用户设备物理层可以将接收到的第一数据包发送至网络设备，在用户设备物理层发送第一数据包时若检测到目标场景，则停止发送第一数据包，并向用户设备MAC层反馈第一数据包停止发送的通知信息。用户设备MAC层在接收到用户设备物理层反馈的通知信息之后，可以获知第一数据包在用户设备物理层停止发送，此时用户设备MAC层可以停止CGT和/或CGRT并在CGT和/或CGRT停止后发送第一数据包。
本公开实施例中，用户设备物理层在发送第一数据包时若检测到目标场景则停止向网络设备发送第一数据包并通知用户设备MAC层，便于用户设备MAC层及时获知第一数据包的发送状态，进而采集对应措施以保证用户设备的数据传输，节省时延。
在本公开一可选实施例中，所述用户设备物理层在发送所述第一数据包时检测到目标场景的情况下，停止发送所述第一数据包，包括以下方式其中之一：
所述用户设备物理层在发送所述第一数据包时获取到满足预设条件的第二数据包的情况下，停止发送所述第一数据包；
所述用户设备物理层在发送所述第一数据包时接收到网络设备发送的指示所述第一数据包传输中断的第一指示信息的情况下，停止发送所述第一数据包；
所述用户设备物理层在发送所述第一数据包时接收到所述网络设备发送 的指示用户设备变更时隙的第二指示信息的情况下，停止发送所述第一数据包。
用户设备物理层可以在发送第一数据包时获取到满足预设条件的第二数据包的情况下，停止向网络设备发送第一数据包，其中第二数据包可以为用户设备MAC层向用户设备物理层递交的另一数据包，也可以为用户设备物理层本身所生成的数据包。即，在用户设备物理层向网络设备发送第一数据包的过程中，若接收到用户设备MAC层递交的满足预设条件的第二数据包，则可以停止向网络设备发送第一数据包。或者在用户设备物理层向网络设备发送第一数据包的过程中，用户设备物理层产生了满足预设条件的第二数据包，则可以停止向网络设备发送第一数据包。
若用户设备物理层在发送第一数据包时接收到网络设备发送的指示第一数据包传输中断的第一指示信息，则可以停止向网络设备发送第一数据包。即，在用户设备物理层向网络设备发送第一数据包的过程中，若接收到网络设备发送的指示第一数据包传输中断的第一指示信息，则可以根据网络设备发送的第一指示信息，停止向网络设备发送第一数据包。
若用户设备物理层在发送第一数据包时接收到网络设备发送的指示用户设备变更时隙的第二指示信息，则可以停止向网络设备发送第一数据包。即，在用户设备物理层向网络设备发送第一数据包的过程中，若接收到网络设备发送的指示用户设备变更时隙的第二指示信息，则可以根据网络设备发送的第二指示信息，停止向网络设备发送第一数据包。
在本公开实施例中，可以基于数据包的获取情况或者网络设备的指示，停止向网络设备发送第一数据包，实现根据用户设备或者网络设备的触发控制第一数据包停发。
在本公开一可选实施例中，所述用户设备物理层在发送所述第一数据包时获取到满足预设条件的第二数据包的情况下，停止发送所述第一数据包，包括：
所述用户设备物理层在发送所述第一数据包时，接收到所述用户设备MAC层递交的第二媒体接入控制协议数据单元MAC PDU或者在所述用户设备物理层生成上行控制信息UCI的情况下，停止发送所述第一数据包；
其中，所述第二数据包为所述第二MAC PDU或者所述UCI，所述第一 数据包为第一MAC PDU，所述第一数据包通过第一配置授权资源向网络设备发送，所述第二数据包通过第一目标上行资源向所述网络设备发送，所述第二数据包的优先级高于所述第一数据包的优先级和/或所述第一目标上行资源的优先级高于所述第一配置授权资源的优先级。
用户设备MAC层向用户设备物理层递交的数据包均为MAC PDU，因此第一数据包为第一MAC PDU，若第二数据包为用户设备MAC层向用户设备物理层递交的数据包，则第二数据包为第二MAC PDU。其中，第一数据包通过第一配置授权资源向网络设备发送，第二数据包通过第一目标上行资源向网络设备发送，配置授权资源为在上行资源中所选择，且配置授权资源可以周期性使用，实现节省PDCCH开销。
在第二数据包为第二MAC PDU的情况下，根据满足预设条件的第二数据包停止向网络设备发送第一数据包，具体过程可以为：若用户设备物理层在发送第一数据包时，接收到用户设备MAC层递交的第二MAC PDU，且第二MAC PDU的优先级高于第一数据包(第一MAC PDU)的优先级，则可以停止第一数据包的发送。具体过程还可以为：若用户设备物理层在发送第一数据包时，接收到用户设备MAC层递交的第二MAC PDU，且用于发送第二MAC PDU的第一目标上行资源的优先级高于用于发送第一数据包的第一配置授权资源的优先级，则可以停止第一数据包的发送。具体过程还可以为：若用户设备物理层在发送第一数据包时，接收到用户设备MAC层递交的第二MAC PDU，且用于发送第二MAC PDU的第一目标上行资源的优先级高于用于发送第一数据包的第一配置授权资源的优先级，同时第二MAC PDU的优先级高于第一数据包的优先级，则可以停止第一数据包的发送。
在第二数据包为用户设备物理层生成的上行控制信息(Uplink Control Information，UCI)的情况下，根据满足预设条件的第二数据包停止向网络设备发送第一数据包，具体过程可以为：若用户设备物理层在发送第一数据包时，生成了UCI，且用户设备物理层生成的UCI的优先级高于第一数据包(第一MAC PDU)的优先级，则可以停止第一数据包的发送。具体过程还可以为：若用户设备物理层在发送第一数据包时，生成了UCI，且用于发送UCI的第一目标上行资源的优先级高于用于发送第一数据包的第一配置授权资源的优先级，则可以停止第一数据包的发送。具体过程也可以为：若用户设备物理 层在发送第一数据包时，生成了UCI，且用于发送用户设备物理层生成的UCI的第一目标上行资源的优先级高于用于发送第一数据包的第一配置授权资源的优先级，同时用户设备物理层生成的UCI的优先级高于第一数据包的优先级，则可以停止第一数据包的发送。
本公开实施例中，可以基于第二MAC PDU的优先级和/或用于发送第二MAC PDU的第一目标上行资源的优先级触发第一数据包的停发，也可以基于UCI的优先级和/或用于发送UCI的第一目标上行资源的优先级触发第一数据包的停发，实现根据更高优先级的数据和/或上行资源触发停止发送第一数据包。
在本公开一可选实施例中，所述用户设备物理层在发送所述第一数据包时获取到满足预设条件的第二数据包的情况下，在停止发送所述第一数据包之后，还包括：
所述用户设备物理层发送所述第二数据包。
针对用户设备物理层在发送第一数据包时获取到满足预设条件的第二数据包的情况，用户设备物理层在停止发送第一数据包之后，可以向网络设备发送第二数据包。这里满足预设条件的第二数据包即为：数据包优先级高于第一数据包优先级和/或用于发送该数据包的上行资源的优先级高于用于发送第一数据包的上行资源的优先级。用户设备物理层通过向网络设备发送第二数据包，可以实现发送优先级更高的数据包和/或发送上行资源的优先级更高的数据包。
在本公开一可选实施例中，所述发送所述第一数据包，包括：
所述用户设备MAC层在至少一个上行资源中选择第二目标上行资源；
所述用户设备物理层通过所述第二目标上行资源向网络设备发送缓存的所述第一数据包。
用户设备MAC层在发送第一数据包时，首先需要在至少一个上行资源中选择第二目标上行资源，在确定第二目标上行资源之后，用户设备即可采用第二目标上行资源向网络设备发送缓存在用户设备MAC层的第一数据包。具体为：用户设备MAC层在确定第二目标上行资源之后，用户设备物理层通过用户设备MAC层所确定的第二目标上行资源，向网络设备发送缓存在用户设备MAC层的第一数据包。
在本公开一可选实施例中，所述第一数据包通过第一配置授权资源首次向所述网络设备发送；所述用户设备MAC层在至少一个上行资源中选择第二目标上行资源，包括：
所述用户设备MAC层根据上行资源的调制编码方式MCS和上行资源的可靠性参数中的至少一个，在所述至少一个上行资源中选择所述第二目标上行资源。
第一数据包在首次向网络设备发送时通过第一配置授权资源发送，用户设备MAC层在至少一个上行资源中选择第二目标上行资源时，可以根据上行资源的MCS在至少一个上行资源中选择第二目标上行资源，也可以根据上行资源的可靠性参数在至少一个上行资源中选择第二目标上行资源，还可以根据上行资源的MCS以及上行资源的可靠性参数在至少一个上行资源中选择第二目标上行资源。通过基于上行资源的MCS和上行资源的可靠性参数中的至少一个选择第二目标上行资源，丰富了第二目标上行资源的选择方式。
其中，所述用户设备MAC层根据上行资源的调制编码方式MCS和上行资源的可靠性参数中的至少一个，在所述至少一个上行资源中选择所述第二目标上行资源，包括以下方式其中之一：
所述用户设备MAC层在所述至少一个上行资源中，选择所述MCS低于或者等于所述第一配置授权资源对应的所述MCS的所述第二目标上行资源；
所述用户设备MAC层在所述至少一个上行资源中，选择所述可靠性参数高于或者等于所述第一配置授权资源对应的所述可靠性参数的所述第二目标上行资源；
所述用户设备MAC层在所述至少一个上行资源中，选择所述MCS低于或者等于所述第一配置授权资源对应的所述MCS且所述可靠性参数高于或者等于所述第一配置授权资源对应的所述可靠性参数的所述第二目标上行资源。
在根据上行资源的MCS和上行资源的可靠性参数中的至少一个选择第二目标上行资源时，可以采用以下方案其中之一进行选择。
用户设备MAC层在至少一个上行资源中选择MCS低于或者等于第一配置授权资源对应的MCS的上行资源，将选择出的上行资源作为第二目标上行资源，若根据MCS可以选择出至少两个符合要求的上行资源，可以将首次选择出的上行资源确定为第二目标上行资源，也可以基于预设策略在至少两个 符合要求的上行资源中确定出第二目标上行资源。
用户设备MAC层在至少一个上行资源中选择可靠性参数高于或者等于第一配置授权资源对应的可靠性参数的上行资源，将选择出的上行资源作为第二目标上行资源，若根据可靠性参数可以选择出至少两个符合要求的上行资源，可以将首次选择出的上行资源确定为第二目标上行资源，也可以基于预设策略在至少两个符合要求的上行资源中确定出第二目标上行资源。
用户设备MAC层在至少一个上行资源中选择MCS低于或者等于第一配置授权资源对应的MCS且可靠性参数高于或者等于第一配置授权资源对应的可靠性参数的上行资源，将选择出的上行资源作为第二目标上行资源，若根据MCS和可靠性参数可以选择出至少两个符合要求的上行资源，可以将首次选择出的上行资源确定为第二目标上行资源，也可以基于预设策略在至少两个符合要求的上行资源中确定出第二目标上行资源。
其中，需要说明的是，由于降低的MCS，上行资源的可靠性更高，因此选择MCS低于或者等于第一配置授权资源对应的MCS的上行资源。可靠性参数可以是网络设备为上行资源配置的参数，可靠性参数越大，可靠性越高，例如可以是一些级别参数，0，1，2，3等。其中0表示可靠性最低，数字越大，可靠性越高。
本公开实施例中，通过基于MCS和可靠性参数中的至少一个在上行资源中选择第二目标上行资源，可以在丰富第二目标上行资源的选择方式的基础上，实现选择可靠性高的资源。
在本公开一可选实施例中，所述用户设备MAC层在启动所述CGT和/或所述CGRT之后，该方法还包括：
所述用户设备MAC层设置混合自动重传请求HARQ进程为可执行传输的非悬挂状态；
所述用户设备MAC层在停止所述CGT和/或所述CGRT之后，还包括：
所述用户设备MAC层设置所述HARQ进程为缓存有待发送数据的悬挂状态；
其中，所述用户设备MAC层在设置所述HARQ进程为悬挂状态后发送所述第一数据包。
用户设备MAC层在启动CGT和/或CGRT之后，需要将HARQ进程设 置为可执行传输的非悬挂状态，通过设置HARQ进程的状态，可以表征HARQ缓存中数据已发送。在用户设备MAC层停止CGT和/或CGRT之后，需要将HARQ进程设置为缓存有待发送数据的悬挂状态，通过设置HARQ进程的状态，可以表征HARQ缓存中有数据待发送，在设置HARQ进程为缓存有待发送数据的悬挂状态之后，可以发送缓存的第一数据包。
下面通过两个具体流程对本公开实施例提供的数据传输方法进行阐述。针对用户设备物理层在发送第一数据包时获取到满足预设条件的第二数据包的情况，数据传输方法的具体流程参见图3所示。
步骤301、用户设备MAC层生成第一MAC PDU，将第一MAC PDU递交至用户设备物理层，并打开CGT和/或CGRT，将HARQ进程状态置为可执行传输的非悬挂状态。
步骤302、用户设备物理层通过第一配置授权资源向网络设备发送第一MAC PDU。
步骤303、用户设备物理层接收到用户设备MAC层递交的第二数据包或者在用户设备物理层生成第二数据包的情况下，停止第一MAC PDU的发送，并执行第二数据包的发送，其中，第二数据包的优先级高于第一MAC PDU的优先级和/或用于发送第二数据包的第一目标上行资源的优先级高于用于发送第一MAC PDU的第一配置授权资源的优先级，第二数据包为第二MAC PDU或者UCI。
步骤304、用户设备物理层向用户设备MAC层反馈第一MAC PDU停止发送的通知信息。
步骤305、用户设备MAC层根据通知信息确定第一MAC PDU在用户设备物理层停止发送，停止CGT和/或CGRT，将HARQ进程设置为缓存有待发送数据的悬挂状态。
步骤306、用户设备MAC层选择第二目标上行资源，并在第二目标上行资源上发送第一MAC PDU。
其中，上述实施流程对应的传输机制可参见图4，数据包从MAC层递交到了物理层，开启CGT和CGRT，但是在物理层发生了传输中断(物理层优先发送其他数据或者根据网络设备的指示中断当前数据传输)，MAC层关闭CGT和CGRT，发送数据包，降低了数据传输的时延。
针对用户设备物理层在发送第一数据包时接收到网络设备发送的指示第一数据包传输中断的第一指示信息或者指示用户设备变更时隙的第二指示信息的情况，数据传输方法的具体流程参见图5所示。
步骤501、用户设备MAC层生成第一MAC PDU，将第一MAC PDU递交至用户设备物理层，并打开CGT和/或CGRT，将HARQ进程状态置为可执行传输的非悬挂状态。
步骤502、用户设备物理层通过第一配置授权资源向网络设备发送第一MAC PDU。
步骤503、用户设备物理层接收到网络设备发送的指示第一MAC PDU传输中断的第一指示信息或者接收到网络设备发送的指示用户设备变更时隙的第二指示信息时，停止第一MAC PDU的发送。
步骤504、用户设备物理层向用户设备MAC层反馈第一MAC PDU停止发送的通知信息。
步骤505、用户设备MAC层根据通知信息确定第一MAC PDU在用户设备物理层停止发送，停止CGT和/或CGRT，将HARQ进程设置为缓存有待发送数据的悬挂状态。
步骤506、用户设备MAC层选择第二目标上行资源，并在第二目标上行资源上发送第一MAC PDU。
其中，该实施流程对应的传输机制也可参见图4。
以上为本公开实施例提供的数据传输方法的整体实施过程，通过在用户设备MAC层向用户设备物理层递交第一数据包并启动CGT和/或CGRT之后，在确定第一数据包在用户设备物理层停止发送的情况下，停止CGT和/或CGRT停止并发送第一数据包，可以避免在定时器超时后执行数据传输动作，保证用户设备提前完成数据的传输，节省时延。进一步的，本公开可以实现根据用户设备或者网络设备的触发控制第一数据包停发，还可以在丰富第二目标上行资源的选择方式的基础上，实现选择可靠性高的资源。
