Description

数据传输方法和设备
本申请要求于2019年07月15日提交中国专利局、申请号为201910633800.X、申请名称为“数据传输方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术，尤其涉及一种数据传输方法和设备。
背景技术
新一代无线(new radio，NR)通信系统(简称：NR系统)中引入了配置授权(configured grant，CG)的概念。网络设备为终端设备半静态配置CG资源后，终端设备在有上行数据需要发送时，可以直接使用该CG资源发送承载上行数据的物理上行共享信道(physical uplink shared channel，PUSCH)，无需再等待网络设备的对PUSCH的动态调度。目前，由于CG资源是网络设备单独配置给终端设备的半静态资源，有可能会与终端设备所在的小区的高层配置的资源存在冲突，或和网络设备的动态调度的资源存在冲突，导致PUSCH发送受阻。
超可靠低延迟通信(ultra-reliable and low latency communications，URLLC)业务为NR系统中的一个重要的业务，传输时要求非常高的可靠性和非常短的时延。终端设备在使用CG资源发送URLLC业务的上行数据时，若遇到PUSCH发送受阻的场景，会导致URLLC业务的传输时延增大，可能出现无法满足URLLC业务的时延需求的情况。考虑到URLLC业务的时延需求，现有技术中提出如下两种解决方案：第一种方案：网络设备通过调度尽量避免上述的PUSCH发送受阻的场景出现，但是该方案会影响网络设备调度的灵活性。第二种方案：网络设备为终端设备配置多个CG资源。但是，当有多个CG资源都没有出现PUSCH发送受阻的场景时，因网络设备不确定终端设备会使用哪个CG资源的上行传输机会发送上行数据，因此，网络设备需要在该多个CG资源上检测来自终端设备的上行数据，增加了网络设备检测的复杂度。另外，因上行资源有限，采用为终端设备配置多个CG资源的方案会导致上行资源的开销较大。当终端设备的数量较多时，可能会因能够动态调度的上行资源过少，而阻塞动态调度的PUSCH发送。
故，如何在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务的上行数据的时延是一个亟待解决的问题。
发明内容
本申请实施例提供一种数据传输方法和设备，用于解如何在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务的上行数据的时延的 技术问题。
第一方面，本申请实施例提供一种数据传输方法。该方法可以应用于终端设备，该终端设备包括终端(例如移动电话)或应用于该终端中的芯片。下面以应用于终端设备为例对该方法进行描述，该方法中，终端设备可以获取第一资源和第二资源。其中，所述第一资源配置有至少一个第一上行传输机会，所述第二资源配置有第二上行传输机会。所述第一上行传输机会包括X个重复的第一上行传输资源，所述第二上行传输机会包括Y个重复的第二上行传输资源，所述X和所述Y均为大于或等于1的整数。
在该场景下，若所述第二上行传输机会之前的最近N个第一上行传输机会发送受阻，则所述终端设备使用所述第二上行传输机会向网络设备发送上行数据。若所述第二上行传输机会之前的最近N个第一上行传输机会中至少有一个第一上行传输机会发送未受阻，则所述终端设备确定所述第二上行传输机会不能用于发送上行数据。此时，该第二资源可以被网络设备调度给其他终端设备使用。上述N为大于或等于1的整数。示例性的，所述N为预设的。或者，所述方法还包括：所述终端设备接收来自所述网络设备的第二指示信息，所述第二指示信息指示所述N。
上述方法通过为终端设备配置作为主资源的第一资源和作为备用资源的第二资源，从而在作为主资源的第一资源遇到上述PUSCH发送受阻的场景时，终端设备可以使用作为备用资源的第二资源发送上行数据，以确保上行数据的时延。相应地，如果第一资源未遇到上述PUSCH发送受阻的场景，则网络设备可以将第二资源调度给其他终端设备使用。在通过该方式传输URLLC业务的上行数据时，可以在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务的上行数据的时延。

具体实施方式
图1是本申请实施例应用的移动通信系统的架构示意图。如图1所示，该移动通信系统可以包括核心网设备110、无线接入网设备120和至少一个终端设备(如图1中的终端设备130和终端设备140)。终端设备通过无线的方式与无线接入网设备120相连，无线接入网设备120通过无线或有线方式与核心网设备110连接。核心网设备110与无线接入网设备120可以是独立的不同的物理设备，也可以是将核心网设备110的功能与无线接入网设备120的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备110的功能和部分的无线接入网设备120的功能。终端设备可以是固定位置的，也可以是可移动的。图1只是示意图，该移动通信系统中还可以包括其它网络设备，例如还可以包括无线中继设备和无线回传设备等，在图1中未画出。本申请实施例对该移动通信系统中包括的核心网设备110、无线接入网设备120和终端设备的数量不做限定。
无线接入网设备120是无线网络中的设备，例如将终端设备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：5G移动通信系统或新一代无线(new radio，NR)通信系统中的基站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设备等。本申请实施例对无线接入网设备120所采用的具体技术和具体设备形态不做限定。在本申请实施例中，无线接入网设备120简称网络设备，如果无特殊说明，在本申请实施例中，网络设备均指无线接入网设备120。另外，在本申请实施例中，术语5G和NR可以等同。
终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、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、车载设备等。目前，一些终端设备的举例为：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、智慧家庭(smart home)中的无线终端等。
无线接入网设备120和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请实施例对无线接入网设备120和终端设备的应用场景不做限定。
无线接入网设备120和终端设备之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过免授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信。无线接入网设备120和终端设备之间可以通过6吉兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请实施例对无线接入网设备120和终端设备之间所使用的频谱资源不做限定。
以上述图1所示的移动通信系统为NR移动通信系统(简称：NR系统)为例，在NR系统中，终端设备可以通过如下三种方式向网络设备发送物理上行共享信道(physical uplink shared channel，PUSCH)：
方式一、使用网络设备为终端设备动态调度的资源发送PUSCH。即终端设备每接收到网络设备的一次上行调度，可以发送一次PUSCH。
方式二、使用网络设备半静态配置的配置授权(configured grant，CG)资源发送PUSCH。即，终端设备在有PUSCH需要发送时，无需再等待网络设备的动态调度，可以直接使用该CG资源发送PUSCH。
应理解，PUSCH主要承载的是上行数据，因此，终端设备向网络设备发送PUSCH也 可以称为终端设备向网络设备发送上行数据。在本申请实施例中，PUSCH和上行数据等同，对此不进行区分。
目前，终端设备可以使用上述CG资源进行上行数据的初传。若网络设备未正确接收到终端设备初传的上行数据，则网络设备后续可以动态的调度重传该上行数据的资源(简称：重传调度)，以使终端设备使用动态调度的资源重传该上行数据(即采用方式一进行上行数据的重传)。若终端设备在初传该上行数据后，未接收到网络设备的重传调度，则终端设备确定网络设备正确接收到初传的上行数据。
下面对CG资源进行说明和介绍。在NR系统中，CG资源为非动态调度的资源，可以包括如下两种类型：
第一类型的CG资源(即configured grant Type 1)：网络设备通过高层信令无线资源控制(radio resource control，RRC)信令为终端设备半静态的配置第一类型的CG资源的时频信息，以及，第一类型的CG资源对应的传输参数。该第一类型的CG资源在配置给终端设备后，终端设备在有上行数据需要发送时，可以直接使用该第一类型的CG资源发送上行数据，无需等待网络设备的动态调度。在一些实施例中，第一类型的CG资源也可以称为配置的上行链路授权(即configured uplink grant)、或者，免授权(grant free)资源等。
第二类型的CG资源(即configured grant Type 2)：网络设备通过RRC信令为终端设备半静态的配置第二类型的CG资源对应的传输参数。该第二类型的CG资源在配置给终端设备后，若网络设备后续通过物理层的下行控制信息(downlink control information，DCI)激活该第二类型的CG资源，以及，配置该第二类型的CG资源的时频信息，则终端设备在有上行数据需要发送时，可以直接使用该第二类型的CG资源发送上行数据，无需等待网络设备的动态调度。若网络设备通过DCI去激活该第二类型的CG资源，或者，网络设备未激活该第二类型的CG资源，则终端设备不能使用该第二类型的CG资源发送上行数据。在一些实施例中，该第二类型的CG资源也可以称为基于L1信令的配置上行链路授权(即configured uplink grant based on L1signalling)，或者，上行半静态调度(semi-persistent scheduling，SPS)资源等。
需要说明的是，网络设备可以通过RRC信令的信息元素(information element，IE)资源配置(即configuredGrantConfig)中是否包括rrc-ConfiguredUplinkGrant参数，来表示该高层信令所配置的CG资源是哪种类型的CG资源。当RRC信令的IE configuredGrantConfig中包括rrc-ConfiguredUplinkGrant参数时，说明该RRC信令配置的CG资源为第一类型的CG资源。当RRC信令的IE configuredGrantConfig中不包括rrc-ConfiguredUplinkGrant参数时，说明该RRC信令配置的CG资源为第二类型的CG资源。
图2为一种CG资源的示意图，如图2所示，不管是第一类型的CG资源还是第二类型的CG资源，均配置有至少一个上行传输机会，每个上行传输机会可以包括至少一个重复的上行传输资源，每个上行传输资源可以用于传输一次该上行数据。该上行传输资源在时域上可以占用至少一个符号。也就是说，一个上行传输机会包括多少个上行传输资源，就能重复传输该上行数据多少次。图2是以CG资源配置有2个上行传输机会，每个上行传输机会包括4个重复的上行传输资源为例的示意图。即，该图2所示的一个上行传输机会可以重复传输一个上行数据4次。应理解，这里所说的上行传输机会也可以称为候选上行传输机会，即，终端设备可以使用该上行传输机会发送上行数据。
需要说明的是，一个上行传输机会所包括的上行传输资源可以是在时间上连续的上行传输资源，也可以是在连续的时间单元上重复的传输资源。以NR系统为例，这里所说的时间单元例如可以为NR系统中的时隙(slot)。以图2所示的CG资源的一个上行传输机会为例，若该上行传输机会所包括的上行传输资源是在连续的slot上重复的传输资源，则该上行传输机会的第1个上行传输资源例如可以位于slot n，第2个上行传输资源例如可以位于slot n+1，第3个上行传输资源例如可以位于slot n+2，第4个上行传输资源例如可以位于slot n+3，各上行传输资源在自己所在的slot中的位置相同(例如均为slot中的第2和第3个符号上)。若该上行传输机会所包括的上行传输资源是在时间上连续的上行传输资源，以slot为例，则该上行传输机会的第1个上行传输资源例如可以位于slot n的第2和第3个符号上，第2个上行传输资源例如可以位于slot n的第4和第5个符号上，第3个上行传输资源例如可以位于slot n的第6和第7个符号上，第4个上行传输资源例如可以位于slot n的第8和第9个符号上。
下面结合图2所示的CG资源，通过表1对网络设备如何通过高层信令为终端设备配置第一类型的CG资源的时频信息，以及，第一类型的CG资源对应的传输参数进行说明：
表1
Figure PCTCN2020099666-appb-000001
其中，周期(即Periodicity)、重复次数(即repK)、上行传输机会中各上行传输资源允许传输的上行数据的冗余版本(即repK-RV)为传输参数，时域偏移量、时域资源分配、频域资源分配三者共同指示了CG资源的时频信息。应理解，上述将周期(即Periodicity)、重复次数(即repK)、上行传输机会中各上行传输资源允许传输的上行数据的冗余版本(即repK-RV)称为传输参数仅是便于后续描述，并非是对该三个参数的限定。
Periodicity：简称P，表示CG资源中相邻的两个传输机会的时间间隔，2个符号≤P≤5120个时间单元。
repK：简称K，表示每个上行传输机会包含的重复的上行传输资源的个数。通常的，K的取值包括{1,2,4,8}。当P小于等于1个时间单元时，K取值为1。
上行传输机会中各上行传输资源允许传输的上行数据的冗余版本(redundancy version，RV)：简称repK-RV，表示K个重复的上行传输资源允许传输的RV版本图案。例如，针对K个重复的上行传输资源中第q个上行传输资源允许传输的RV版本图案为：RV序列中的第(mod(n-1,4)+1)个RV版本图案，其中q＝1,2,…,K。
repK-RV有4种情况：不配置，配置为{0,2,3,1}，配置为{0,3,0,3}，配置为{0,0,0,0}。应理解，当K等于1时，不配置repK-RV，即，该repK-RV的取值为0。在该场景下，该CG资源的上行传输机会中的上行传输资源允许传输的RV版本图案为RV序列中第0个 RV版本图案。示例性的，以K等于4为例，repK-RV配置为{0,2,3,1}，若终端设备使用该第一类型的CG资源的一个上行传输机会初传上行数据，则终端设备可以在该上行传输机会中的第一个上行传输资源上传输该上行数据的第0个RV版本图案，在该上行传输机会中的第二个上行传输资源上传输该上行数据的第2个RV版本图案，在该上行传输机会中的第三个上行传输资源上传输该上行数据的第3个RV版本图案，在该上行传输机会中的第四个上行传输资源上传输该上行数据的第1个RV版本图案。
时域偏移量(即timeDomainOffset)：表示在时域上，CG资源相对于“编号为0”的系统帧的偏移量。
时域资源分配(即timeDomainAllocation)：表示时域上PUSCH的映射参数，例如，映射PUSCH的起始符号和时间长度。
频域资源分配(即frequencyDomainAllocation)：表示映射PUSCH的频域资源。
应理解，上述表1仅示出了RRC信令中与CG资源相关的参数，本申请实施例对RRC信令中所包括的其他参数不再赘述。
下面结合图2所示的CG资源，通过表2对网络设备如何通过高层信令为终端设备配置第二类型的CG资源对应的传输参数，通过激活该第二类型的CG资源的DCI为终端设备配置该第二类型的CG资源的时频信息进行说明：
表2
Figure PCTCN2020099666-appb-000002
其中，周期(即Periodicity)、重复次数(即repK)、上行传输机会中各上行传输资源允许传输的上行数据的冗余版本(即repK-RV)为传输参数，时域资源分配、频域资源分配两者共同指示了CG资源的时频信息。关于P、repK、repK-RV可以参见前述描述，在此不再赘述。
时域资源分配(即time domain resource assignment)：表示时域上PUSCH的映射参数，例如，映射PUSCH的起始符号和时间长度。
频域资源分配(即frequency domain resource assignment)：表示映射PUSCH的频域资源。
应理解，上述表2仅示出了RRC信令中和DCI中与CG资源相关的参数，本申请实施例对RRC信令中和DCI中所包括的其他参数不再赘述。
通过上述表1和表2可以看出，第一类型的CG资源由高层信令(即RRC信令)配置，第二类型的CG资源由高层信令(即RRC信令)和激活该CG资源的DCI(例如DCI 0_0/DCI0_1)共同配置。
下述申请文件均以CG资源为例进行说明，该CG资源可以是第一类型的CG资源， 也可以是第二类型的CG资源，本申请实施例对此不进行区分。
由于上述所描述的CG资源为网络设备配置给终端设备的，当K的取值大于1时，有可能会与终端设备所在的小区的高层配置存在冲突，导致PUSCH发送受阻。例如，可以包括如下几种PUSCH发送受阻的场景：
第一种场景：高层信令通过CG资源配置给终端设备发送PUSCH的符号(简称：PUSCH符号A)，被时间单元配置相关的高层信令(例如tdd-UL-DL-ConfigurationCommon或者tdd-UL-DL-ConfigurationDedicated)配置为下行符号。
在该场景下，该PUSCH符号A所在的上行传输资源不能用于发送PUSCH(或者该PUSCH符号A不能用于发送PUSCH)。此时，该PUSCH符号A所在的上行传输资源可以视为发送受阻。
应理解，对于第一类型的CG资源来说，第一类型的CG资源的每个上行传输机会中的所有的上行传输资源中包含的符号都可以称为PUSCH符号A。对于第二类型的CG资源，除了接收到激活该第二类型的CG资源的DCI(例如DCI format0_0或0_1)之后的第一个上行传输机会之外，第二类型的CG资源的其它传输机会中的所有的上行传输资源中包含的符号都可以称为PUSCH符号A。
第二种场景：PUSCH符号A被时间单元配置相关的高层信令半静态配置为灵活的(flexible)符号，或者没有高层参数进行上下行的半静态配置。后续，网络设备通过DCI(例如DCI format 1_0/1_1/0_1)指示该PUSCH符号A为下行符号。该下行信号可以用于发送物理下行共享信道(physical downlink shared channel，PDSCH)或信道状态信息(channel state information，CSI)-参考信号(reference signal，RS)。
在该场景下，该PUSCH符号A所在的上行传输资源不能用于发送PUSCH(或者该PUSCH符号A不能用于发送PUSCH)，除非该PUSCH符号A是可能来不及取消发送PUSCH的符号。此时，该PUSCH符号A所在的上行传输资源可以视为发送受阻。应理解，这里所谓可能来不及取消发送PUSCH的符号是指上述DCI的最后一个符号之后的N2个符号。该N2可以根据终端设备的PUSCH定时能力(timing capability)对应的PUSCH准备时间确定。
示例性的，以时间单元为NR系统的slot为例，终端设备在slot n的第3个符号上接收到DCI，PUSCH符号A为slot n的第5个符号，终端设备在slot n的第6个符号完成对DCI的解析，获知DCI指示该PUSCH符号A为下行符号。此时，若终端设备已经使用PUSCH符号A完成上行数据的发送，该PUSCH符号A即为来不及取消发送PUSCH的符号。终端设备使用PUSCH符号A所发送的上行数据会被网络设备在该符号上所发送的下行数据干扰，导致该上行数据发送失败。该场景下，该PUSCH符号A所在的上行传输资源可以视为发送受阻。
第三种场景：PUSCH符号A被时间单元配置相关的高层信令半静态配置为灵活的(flexible)符号，或者没有高层参数进行上下行的半静态配置。同时，终端设备被配置要检测用于进行时间单元格式指示的DCI、且检测到DCI。其中，DCI指示PUSCH符号A为下行符号或flexible符号。以时间单元为slot为例，则该DCI例如可以为用于进行时隙格式指示(slot format indicator，SFI)的DCI，例如DCI format 2_0。
在该场景下，该PUSCH符号A所在的上行传输资源不能用于发送PUSCH(或者该 PUSCH符号A不能用于发送PUSCH)，除非该PUSCH符号A是可能来不及取消发送PUSCH的符号。此时，该PUSCH符号A所在的上行传输资源可以视为发送受阻。
关于来不及取消发送PUSCH的符号的描述可以参见前述第二种场景中的描述。
第四种场景：PUSCH符号A被时间单元配置相关的高层信令半静态配置为灵活的(flexible)符号，或者没有高层参数进行上下行的半静态配置。同时，终端设备被配置要监听用于进行时间单元格式指示的DCI、但是未监听到该DCI。
在该场景下，该PUSCH符号A所在的上行传输资源不能用于发送PUSCH(或者该PUSCH符号A不能用于发送PUSCH)，除非该PUSCH符号A是可能来不及取消发送PUSCH的符号。此时，该PUSCH符号A所在的上行传输资源可以视为发送受阻。
关于来不及取消发送PUSCH的符号的描述可以参见前述第二种场景中的描述。
第五种场景：对于第二类型的CG资源，终端设备接收到激活该第二类型的CG资源的DCI(例如DCI format0_0或0_1)之后的第一个上行传输机会的上行传输资源中包含的符号(简称：PUSCH符号B)，被时间单元配置相关的高层信令配置为下行符号。
在该场景下，该PUSCH符号B所在的上行传输资源不能用于发送PUSCH(或者说该PUSCH符号B不能用于发送PUSCH)，此时，该PUSCH符号B所在的上行传输资源可以视为发送受阻。
超可靠低延迟通信(ultra-reliable and low latency communications，URLLC)业务为NR系统中的一个重要的业务，传输时要求非常高的可靠性和非常短的时延。终端设备在使用CG资源发送URLLC业务的上行数据时，若遇到上述所示的PUSCH发送受阻的场景，会导致URLLC业务的传输时延增大，可能出现无法满足URLLC业务的时延需求的情况。
图3为一种URLLC业务的传输示意图。如图3所示，若URLLC业务的上行数据到达的时刻之后的第一个上行传输机会未出现发送受阻的情况，则终端设备可以直接使用该第一个上行传输机会发送URLLC业务的上行数据。在该场景下，URLLC业务的时延是时延1。若URLLC业务的上行数据到达的时刻之后的第一个上行传输机会出现发送受阻的情况，但第二个上行传输机会未出现发送受阻。此时，终端设备使用该第二个上行传输机会发送URLLC业务的上行数据，会使URLLC业务的时延增大至时延2。若该时延2超出URLLC业务的最大时延需求，则该次上行数据的传输无法满足URLLC业务的时延需求。关于上行传输机会发送受阻的介绍可以参见后续描述。
考虑到URLLC业务的时延需求，传统技术中提出如下两种解决方案：
第一种方案：网络设备通过调度尽量避免上述的PUSCH发送受阻的场景出现，但是该方案会影响网络设备调度的灵活性。
第二种方案：网络设备为终端设备配置多个CG资源。
但是，当有多个CG资源都没有出现PUSCH发送受阻的场景时，因网络设备不确定终端设备会使用哪个CG资源的上行传输机会发送上行数据，因此，网络设备需要在该多个CG资源上检测来自终端设备的上行数据，增加了网络设备检测的复杂度。另外，因上行资源有限，采用为终端设备配置多个CG资源的方案会导致上行资源的开销较大。当终端设备的数量较多时，可能会因能够动态调度的上行资源过少，而阻塞动态调度的PUSCH发送。
故，如何在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下， 减小传输URLLC业务的上行数据的时延是一个亟待解决的问题。
考虑到上述问题，本申请实施例提供了一种数据传输方法，通过为终端设备配置作为主资源的第一资源和作为备用资源的第二资源，从而在作为主资源的第一资源遇到上述PUSCH发送受阻的场景时，终端设备可以使用作为备用资源的第二资源发送上行数据，以确保上行数据的时延。相应地，如果第一资源未遇到上述PUSCH发送受阻的场景，则网络设备可以将第二资源调度给其他终端设备使用。在通过该方式传输URLLC业务的上行数据时，可以在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务的上行数据的时延。应理解，本申请实施例所提供的方法包括但不限于传输URLLC业务的上行数据的场景，可以适用于任意发送上行数据的场景，对此不再赘述。另外，本申请实施例的方法包括但不限于初次传输上行数据的场景，也可以适用于重传上行数据的场景。
下面通过一些实施例对本申请的技术方案进行详细说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不加赘述。
图4为本申请实施例提供的一种数据传输方法的流程示意图。如图4所示，该方法可以包括：
S101、终端设备获取第一资源和第二资源；其中，所述第一资源配置有至少一个第一上行传输机会，所述第二资源配置有第二上行传输机会，所述第一上行传输机会包括X个重复的第一上行传输资源，所述第二上行传输机会包括Y个重复的第二上行传输资源，所述X和所述Y均为大于1的整数。
S102、若所述第二上行传输机会之前的最近N个第一上行传输机会发送受阻，则所述终端设备使用所述第二上行传输机会向网络设备发送上行数据，所述N为大于或等于1的整数。
在本实施例中，终端设备配置有配置作为主资源的第一资源和作为备用资源的第二资源。该第一资源和第二资源可以是前述所说的半静态配置的CG资源(即非动态调度的资源)，也可以是网络设备动态为终端设备调度的资源。例如，所述第一资源和所述第二资源均为第一类型的CG资源，或者，所述第一资源为第一类型的CG资源、所述第二资源为第二类型的CG资源，或者，所述第一资源为第一类型的CG资源、所述第二资源为动态调度的资源，或者，所述第一资源和所述第二资源均为第二类型的CG资源，或者，所述第一资源为第二类型的CG资源、所述第二资源为第一类型的CG资源，或者，所述第一资源为第二类型的CG资源、所述第二资源为动态调度的资源，或者，所述第一资源和所述第二资源均为动态调度的资源，或者，所述第一资源为动态调度的资源、所述第二资源为第一类型的CG资源，或者，所述第一资源为动态调度的资源、所述第二资源为第二类型的CG资源等。
应理解，上述第二资源可以配置有至少一个第二上行传输机会，该至少一个第二上行传输机会可以周期性的出现。以第一资源和第二资源均为CG为例，则在示例下，第一资源配置的至少一个第一上行传输机会的周期P，与第二资源配置的至少一个第二上行传输机会的周期P可以相同，也可以不同。即，第一资源配置的至少一个第一上行传输机会与第二资源配置的至少一个第二上行传输机会出现的频率相同，也可以不同。相应地，一个第一上行传输机会包括的重复的第一上行传输资源的数量X，与一个第二上行传输机会包 括的重复的第二上行传输资源的数量Y可以相等，也可以不相等。
下面，以第一资源配置的第一上行传输机会包括4个重复的第一上行传输资源、以第二资源配置的第二上行传输机会包括3个重复的第二上行传输资源为例，对上述第一资源和第二资源在时域和频域上的关系进行示例说明：
图5为本申请实施例提供的一种资源分布示意图，图6为本申请实施例提供的另一种资源分布示意图。第一资源配置的第一上行传输机会与第二资源配置的第二上行传输机会在时域上的关系可以如图5和图6所示，即，至少一个第一上行传输机会中的一个第一上行传输机会之后的一个第二上行传输机会在时域上与该第一上行传输机会相邻。在该示例下，第一资源配置的第一上行传输机会与第二资源配置的第二上行传输机会在频域上可以位于相同的频段，即频域相同(例如图6所示)，也可以位于不同的频段，即频域不同(例如图5所示)。
图7为本申请实施例提供的又一种资源分布示意图，图8为本申请实施例提供的又一种资源分布示意图。第一资源配置的第一上行传输机会与第二资源配置的第二上行传输机会在时域上的关系可以如图7和图8所示，即，至少一个第一上行传输机会中的一个第一上行传输机会之后的一个第二上行传输机会在时域上与该第一上行传输机会不相邻。在该示例下，第一资源配置的第一上行传输机会与第二资源配置的第二上行传输机会在频域上可以位于相同的频段，即频域相同(例如图8所示)，也可以位于不同的频段，即频域不同(例如图7所示)。
图9为本申请实施例提供的一种数据传输示意图。如图9所示，为了便于对本申请实施例的描述，本申请实施例以第二资源配置的一个第二上行传输机会为例进行说明，该第二上行传输机会例如可以为上行数据到达终端设备的时刻之后的第一个第二上行传输机会，即图9中所标记的第二上行传输机会。在本实施例中，当终端设备有上行数据需要发送时，终端设备可以判断该第二上行传输机会之前的最近N个第一上行传输机会是否发送受阻。若该N个第一上行传输机会发送受阻，说明作为主资源的第一资源会因为发送受阻影响上行数据的发送，因此，终端设备可以直接使用作为备用资源的第二资源的该第二上行传输机会发送上行数据。即，在主资源发送受阻时，终端设备可以尽快的使用备用资源将上行数据发送出去。通过该方式，可以保证上行数据的传输时延，避免因发送受阻导致上行数据传输时延较大的问题。
当第一资源配置的第一上行传输机会与第二资源配置的第二上行传输机会在时域上的关系可以如图5和图6所示时，即，至少一个第一上行传输机会中的一个第一上行传输机会之后的一个第二上行传输机会在时域上与该第一上行传输机会相邻时，在作为主资源的第一资源发送受阻时，终端设备可以立刻使用第二资源配置的第二上行传输机会将上行数据发送出去，进一步缩短了上行数据的传输时延。
应理解，这里所说的最近N个第一上行传输机会是第一资源配置的至少一个第一上行传输机会中的部分第一上行传输机会，该N个第一上行传输机会可以为连续的N个第一上行传输机会。本实施例不限定上述N的取值。图9是以N为3为例的示意图。作为一种可能的实现方式，该N可以为预设的，例如，该N的取值可以为协议预定义的。或者，该N可以为网络设备通过指示信息发送给终端设备的。例如，网络设备向终端设备发送第二指示信息，该第二指示信息指示该N。相应地，终端设备接收该第二指示信息，并通过该第 二指示信息获取该N。可选的，该第二指示信息可以承载于高层信令或物理层信令中。或者说，所述高层信令或物理层信令指示该N。
若该第二上行传输机会之前的最近N个第一上行传输机会中至少有一个第一上行传输机会发送未受阻，说明作为主资源的第一资源可能不会因为发送受阻造成上行数据的发送延时过大，则终端设备确定第二上行传输机会不能用于发送上行数据。即，终端设备确定不使用第二资源。在该场景下，终端设备例如可以使用上行数据到达终端设备的时刻之后的第一个第一上行传输机会发送上行数据。
相应地，网络设备可以采用上述所说的方式判断第二资源的每个第二上行传输机会之前的最近N个第一上行传输机会是否发送受阻。若该N个第一上行传输机会发送受阻，则网络设备在该第二上行传输机会上检测是否有来自终端设备的上行数据。若该N个第一上行传输机会未发送受阻，则网络设备确定该第二上行传输机会不能用于发送上行数据。此时，网络设备可以继续在第一上行传输机会上检测是否有来自终端设备的上行数据。在该场景下，网络设备可以将第二资源暂时调度给其他终端设备使用。也就是说，在第一资源未因发送受阻影响上行数据发送时，第二资源可以被网络设备暂时调度给其他终端设备使用。通过这种方式，可以保证网络设备的调度灵活性，减少网络设备检测的复杂度，以及，降低上行资源的开销。
图10为本申请实施例提供的另一种数据传输示意图。如图10所示，本实施例以第二资源配置的两个第二上行传输机会(第二上行传输机会1和第二上行传输机会2)为例进行说明。假定N等于3。在本实施例中，当终端设备有上行数据需要发送时，终端设备通过上述方式判断得出第二上行传输机会1之前的最近N个第一上行传输机会发送受阻、且第二上行传输机会2之前的最近N个第一上行传输机会发送也受阻。则在该场景下，若第二上行传输机会1可以用于发送上行数据，则第二上行传输机会2不能用于发送上行数据。也就是说，在第二上行传输机会之前的最近N个第一上行传输机会发送受阻的情况下，还要观察该最近N个第一上行传输机会到该第二上行传输机会之间是否还有可用的第二上行传输机会。若有，则本次第二上行传输机会不能用于发送上行数据。若没有，则本次第二上行传输机会可以用于发送上行数据。
下面对如何界定一个第一上行传输机会发送受阻的方式进行详细说明，例如可以包括如下两种方式：
第一种方式：一个第一上行传输机会中的X个重复的第一上行传输资源均发送受阻时，确定该第一上行传输机会发送受阻。
当第一上行传输机会中的所有上行传输资源发送都受阻时，即该第一上行传输机会中的任何一个上行传输资源不能用于发送上行数据时，终端设备可以确定该第一上行传输机会发送受阻。反之，当一个第一上行传输机会中有至少一个第一上行传输资源发送不受阻时，即该第一上行传输机会中有至少一个上行传输资源可以用于发送上行数据时，终端设备可以确定该第一上行传输机会发送未受阻。
在本实施例中，一个第一上行传输资源发送受阻可以是该第一上行传输资源中有至少一个符号为非上行符号。例如，该至少一个符号被配置为下行符号或者flexible的符号，具体可以参见前述描述发送受阻的第一种场景、第二种场景、第三种场景和第五种场景。
或者，一个第一上行传输资源发送受阻可以是该第一上行传输资源中有至少一个符号 为来不及取消发送PUSCH的符号。即，终端设备使用该第一上行传输资源中的至少一个非上行符号发送上行数据，具体可以参见前述描述发送受阻的第二种场景和第三种场景。
需要说明的是，在本实施例中，对于前述描述发送受阻的第四场景(即，终端设备被配置要监听用于进行SFI的DCI、但是未监听到该DCI，而导致的上行传输资源发送受阻的场景)，若终端设备基于该场景判断得到第二上行传输机会之前的最近N个第一上行传输机会发送受阻，也不会引起第二资源(即备用资源)的启用。即，终端设备也不会使用该第二上行传输机会发送上行数据，而是会使用后续发送未受阻的第一上行传输机会发送上行数据。这是因为网络设备无法获知终端设备没有监听到该DCI，因此，网络设备无法基于该场景判断得出第二上行传输机会之前的最近N个第一上行传输机会是否发送受阻的结论。因而，网络设备仍然会在第一资源上检测是否有来自终端设备的上行数据。所以，在该场景下，为了确保数据传输的可靠性，终端设备仍然使用第一资源发送上行数据。
第二种方式：一个第一上行传输机会中发送受阻的第一上行传输资源的数量大于或等于第一预设阈值时，确定该第一上行传输机会发送受阻。其中，该第一预设阈值可以小于或等于一个第一上行传输机会所包括第一上行传输资源的数量X。关于第一上行传输资源发送受阻的判断方式可以参见第一种方式中的描述。
以第一预设阈值小于X为例，则当一个第一上行传输机会中发送受阻的第一上行传输资源的数量大于或等于第一预设阈值时，确定该第一上行传输机会发送受阻。反之，则确定该第一上行传输机会发送未受阻。以第一预设阈值等于X为例，则当一个第一上行传输机会中发送受阻的第一上行传输资源的数量等于第一预设阈值时，确定该第一上行传输机会发送受阻。反之，则确定该第一上行传输机会发送未受阻。
本实施例不限定上述第一预设阈值的取值。作为一种可能的实现方式，该第一预设阈值可以为预设的，例如，该第一预设阈值的取值可以为协议预定义的。或者，该第一预设阈值可以为网络设备通过指示信息发送给终端设备的。例如，网络设备向终端设备发送第一指示信息，该第一指示信息指示该第一预设阈值。相应地，终端设备接收该第一指示信息，并通过该第一指示信息获取该第一预设阈值。可选的，该第一指示信息可以承载于高层信令或物理层信令中。或者说，所述高层信令或物理层信令指示该第一预设阈值。
作为另一种可能的实现方式，所述第一预设阈值可以根据所述第一资源的第一配置参数和/或第二配置参数确定；其中，所述第一配置参数用于配置所述X，所述第二配置参数用于配置所述第一上行传输机会中各第一上行传输资源允许传输的上行数据的冗余版本。例如，该第一配置参数可以为前述所说的repK，第二配置参数例如可以为前述所说的repK-RV。
示例性的，第一预设阈值与repK和/或repK-RV的关系例如可以如下述表3所示：
表3
Figure PCTCN2020099666-appb-000003
通过上述任意一种方式，可以识别出一个第一上行传输机会是否受阻，进而当第二上行传输机会之前的最近N个第一上行传输机会发送受阻时，终端设备可以直接使用作为备用资源的第二资源的该第二上行传输机会发送上行数据，以尽快的使用备用资源将上行数据发送出去。通过该方式，可以保证上行数据的传输时延，避免因发送受阻导致上行数据传输时延较大的问题。
本申请实施例所涉及的第一资源和第二资源可以为预设给终端设备的，也可以为网络设备通过高层信令或物理层信令配置给终端设备的。例如，作为一种可能的实现方式，上述终端设备获取第一资源和第二资源可以为：网络设备向终端设备发送高层信令，其中，该高层信令指示该第一资源和该第二资源。相应地，终端设备通过接收该高层信令，获取该第一资源和第二资源。应理解，这里所说的高层信令例如可以为RRC信令。
下面以高层信令为例，假定第一资源和第二资源均为CG资源，对网络设备如何使用高层信令为终端设备配置第一资源和第二资源进行说明：
第一种情况：第一资源和第二资源均为第一类型的CG资源。
在示例下，高层信令可以包括第一信息域和第二信息域。其中，第一信息域与第一资源对应，第二信息域与第二资源对应。应理解，本申请实施例对高层信令中是否包括其他信息域或者参数不限定。
所述第一信息域包括第一信息子域和/或第二信息子域。其中，所述第一信息子域指示所述第一资源的时频信息。例如，第一信息子域可以包括如前述表1所示的时域偏移量(即timeDomainOffset)、时域资源分配(即timeDomainAllocation)、频域资源分配(即frequencyDomainAllocation)中至少一项参数，以通过该至少一项参数指示所述第一资源的时频信息。所述第二信息子域指示所述第一资源的传输参数，所述第一资源的传输参数可以包括下述至少一项：所述X、所述第一上行传输机会中各第一上行传输资源允许传输的上行数据的冗余版本(例如前述表1所示的repK-RV)、相邻两个第一上行传输机会的时间间隔(例如前述表1所示的周期P)。例如，第二信息子域可以通过包括该至少一项参数来指示所述第一资源的传输参数。应理解，对于第一信息域未指示的、且与配置第一资源有关的参数，可以在高层信令中的其他位置指示，或者，通过其他信令指示，或者，为预设值。
所述第二信息域包括第三信息子域和/或第四信息子域。其中，所述第三信息子域指示所述第二资源的时频信息。例如，第三信息子域可以包括如前述表1所示的时域偏移量(即timeDomainOffset)、时域资源分配(即timeDomainAllocation)、频域资源分配(即frequencyDomainAllocation)中至少一项参数，以通过该至少一项参数指示所述第二资源的时频信息。所述第四信息子域指示所述第二资源的传输参数，所述第二资源的传输参数包括下述至少一项：所述Y、所述第二上行传输机会中各第二上行传输资源允许传输的上行数据的冗余版本(即前述表1所示的repK-RV)、相邻两个第二上行传输机会的时间间隔(例如前述表1所示的周期P)。例如，第四信息子域可以通过包括该至少一项参数来指示所述第二资源的传输参数。应理解，对于第二信息域未指示的、且与配置第二资源有关的参数，可以在高层信令中的其他位置指示，或者，通过其他信令指示，或者，为预设值。
作为一种可能的实现方式，上述第一信息子域、第二信息子域、第三信息子域和第四信息子域中的任一信息子域在高层信令中可以打包成一个IE。当然，本申请实施例对IE 的名称不进行限定。例如，这些IE位于高层信令的IE ConfiguredGrantConfig中。也可以说，第一信息域和第二信息域位于高层信令的IE ConfiguredGrantConfig中。
作为一种可能的实现方式，所述第一信息子域和/或所述第二信息子域还指示所述第一资源的类型；和/或，所述第三信息子域和/或所述第四信息子域还指示所述第二资源的类型。该第一资源的类型和第二资源的类型用于区分该信息子域对应的是哪个资源。例如，可以通过在上述信息子域中携带资源类型参数，来指示资源的类型。例如，类型参数取值为1时，指示该资源为第一资源，类型参数取值为0时，指示该资源为第二资源。或者，类型参数取值为0时，指示该资源为第一资源，类型参数取值为1时，指示该资源为第二资源。
作为一种可能的实现方式，所述终端设备配置有多组资源，其中，每组资源包括一个第一资源，以及，与该第一资源对应的第二资源。在该场景下，所述第一信息子域和/或所述第二信息子域还指示所述第一资源所在组的标识；所述第三信息子域和/或所述第四信息子域还指示所述第二资源所在组的标识。例如，可以通过在上述信息子域中携带组标识。这里所说的组标识例如可以为组的ID、组的索引等。应理解，在使用上述信息子域指示属于同一组的第一资源和第二资源时，可以在其中一个资源对应的信息子域指示其所指示的资源的类型即可，从而可以通过组标识和该资源的类型，区分未指示资源类型的信息子域所指示的资源是什么资源。通过该方式，可以在实现区分两种资源的基础上，降低信令开销。
第二种情况：第一资源和第二资源均为第二类型的CG资源。
在示例下，高层信令可以包括第一信息域和第二信息域。其中，第一信息域与第一资源对应，第二信息域与第二资源对应。应理解，本申请实施例对高层信令中是否包括其他信息域或者参数不限定。
所述第一信息域包括第一信息子域和/或第二信息子域。关于第一信息子域和第二信息子域的描述可以参见前述第一种情况中的描述，在此不再赘述。对于第一信息域未指示的、且与配置第一资源有关的参数，可以在高层信令中的其他位置指示，或者，通过其他信令指示，或者，为预设值。
所述第二信息域包括第三信息子域和/或第四信息子域。关于第三信息子域和第四信息子域的描述可以参见前述第一种情况中的描述，在此不再赘述。应理解，对于第二信息域未指示的、且与配置第二资源有关的参数，可以在高层信令中的其他位置指示，或者，通过其他信令指示，或者，为预设值。
作为一种可能的实现方式，上述第一信息子域、第二信息子域、第三信息子域和第四信息子域中的任一信息子域在高层信令中可以打包成一个IE。当然，本申请实施例对IE的名称不进行限定。例如，这些IE位于高层信令的IE ConfiguredGrantConfig中。也可以说，第一信息域和第二信息域位于高层信令的IE ConfiguredGrantConfig中。
如前述所说，对于第二类型的CG来说，网络设备可以通过RRC信令的IE configuredGrantConfig中不包括rrc-ConfiguredUplinkGrant参数，来表示该高层信令所配置的CG资源是第二类型的CG资源。也就是说，在本申请实施例中，若第一资源和第二资源为第二类型的CG资源，则该高层信令通过在IE configuredGrantConfig中不包括rrc-ConfiguredUplinkGrant参数，来表示该高层信令所配置的CG资源是第二类型的CG资 源。
相应地，该第一资源和第二资源在配置给终端设备后，网络设备可以通过物理层的DCI激活或去激活该第一资源，以及，通过DCI激活或去激活第二资源。在一些实施例中，上述高层信令不携带上述第一信息子域和/或第三信息子域。即，本申请实施例的高层信令保持有现有的高层信令相同的方式，仅在高层信令中指示第一资源的传输参数和/或第二资源的传输参数。这样，当网络设备通过DCI激活或去激活某一资源时，通过该DC进一步指示该资源的时频信息。以激活第一资源为例，该DCI可以携带前述所说的第一信息子域来指示该第一资源。
作为一种可能的实现方式，上述DCI还可以单独指示激活或去激活的资源的类型，以使终端设备获知激活或去激活的资源是哪个资源。和/或，所述第一信息子域和/或所述第二信息子域还指示所述第一资源的类型；和/或，所述第三信息子域和/或所述第四信息子域还指示所述第二资源的类型。关于类型的描述可以参见前述第一种情况中的描述，在此不再赘述。
作为一种可能的实现方式，所述终端设备配置有多组资源，其中，每组资源包括一个第一资源，以及，与该第一资源对应的第二资源。在该场景下，所述控制信息还指示激活或去激活的资源所在组的标识。相应地，所述第一信息子域和/或所述第二信息子域还指示所述第一资源所在组的标识。所述第三信息子域和/或所述第四信息子域还指示所述第二资源所在组的标识。关于组的标识的描述可以参见前述第一种情况中的描述，在此不再赘述。应理解，在使用上控制信息指示激活或去激活的资源所在组的标识时，则可以仅通过控制信息，或者，仅通过指示该资源的信息子域中指示该资源的类型即可。通过该方式，可以在实现区分两种资源的基础上，降低信令开销。
应理解，上述所示的两种情况仅是一种示例，当第一资源为第一类型的CG资源、第二资源为第二类型的CG资源时，对于第一资源可以采用第一种情况所示的方式进行指示，对于第二资源可以采用第二种情况所示的方式指示。相应地，当第一资源为第二类型的CG资源、第二资源为第一类型的CG资源时，对于第一资源可以采用第二种情况所示的方式进行指示，对于第二资源可以采用第一种情况所示的方式指示，对此不再赘述。
通过上述方式，网络设备可以为终端设备配置作为主资源的第一资源和作为备用资源的第二资源，从而在作为主资源的第一资源遇到上述PUSCH发送受阻的场景时，终端设备可以使用作为备用资源的第二资源发送上行数据，以确保上行数据的时延。相应地，如果第一资源未遇到上述PUSCH发送受阻的场景，则网络设备可以将第二资源调度给其他终端设备使用。在通过该方式传输URLLC业务的上行数据时，可以在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务的上行数据的时延。
本申请实施例提供的数据传输方法，通过为终端设备配置作为主资源的第一资源和作为备用资源的第二资源，从而在作为主资源的第一资源遇到上述PUSCH发送受阻的场景时，终端设备可以使用作为备用资源的第二资源发送上行数据，以确保上行数据的时延。相应地，如果第一资源未遇到上述PUSCH发送受阻的场景，则网络设备可以将第二资源调度给其他终端设备使用。在通过该方式传输URLLC业务的上行数据时，可以在不影响网络设备的调度灵活性、检测的复杂度和上行资源开销的情况下，减小传输URLLC业务 的上行数据的时延。

作为一种可能的实现方式，所述第一信息子域和/或所述第二信息子域还指示所述第一资源的类型；和/或，所述第三信息子域和/或所述第四信息子域还指示所述第二资源的类型。
