具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本文所描述的技术不限于第五代移动通信(5th-generation，5G)系统以及后续演进通信系统，以及不限于LTE/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(TimeDivision Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。
本发明实施例提供的终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(PersonalDigital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
现今，在5G系统中，需要采用非授权(NR-U，New RAT Un-licensed)频段进行数据的收发，则信号发送端需要满足非授权频段的使用规则。对于非授权频段，当网络侧给UE进行了CG配置的时候，无法再进行发送信道的优先级配置。因此，对于NR-U频段，在已经进行了CG配置且配置了发送信道的优先级后，如果终端的上行发送由于信道接入失败和/或数据发送优先级较低而失败，终端无法知晓如何进行数据重传。
鉴于此，本公开提供了一种数据重传确定方法和设备，能够提供一种在同时进行CG配置以及发送信道的优先级配置的情况下进行数据重传的方法，从而具有数据发送的高可靠性以及低时延的优点。
图1示出了根据本公开实施例的一种数据重传确定方法的流程示意图。在本实施例中，方法由基站执行，如图1所示，该数据重传确定方法包括以下步骤：
S101，向终端发送上行授权CG配置信息和发送信道的优先级信息，CG配置信息用于在终端根据优先级信息确定发送信道的优先级的情况下，与预置数据重传信息以及发送失败情况决定待采用的数据重传方法。其中，所述CG配置信息包括CG配置类型，所述预置数据重传信息指示数据重传方法、发送失败情况以及CG配置类型之间的对应关系。
在本实施例中，基站向终端发送的配置信息同时包括指示CG配置类型的CG配置信息和发送信道的优先级信息。终端在接收到CG配置信息和优先级信息并在根据优先级信息确定发送信道的优先级的情况下，根据不同CG配置类型和不同发送失败情况，采用不同数据重传方法。其中，预置数据重传信息指示了不同CG配置类型、不同发送失败情况以及不同数据重传方法之间的对应关系。预置数据重传信息可以是基站与终端预先约定并预存于终端侧。
CG配置信息可以包括一个或多个配置项，例如，对于小区1的带宽部分(Bandwidth Part，BWP)可以配置多个配置项(configuredGrantConfig-1和configuredGrantConfig-2)。每个配置项可以指示CG配置类型。
发送信道的优先级信息用于指示发送信道的优先级的确定方式。由于终端不能同时发送多个上行信息，因此，在多个上行信道的发送发生冲突时，终端选择高优先级的信道进行发送。发送信道的优先级的确定方式包括以下至少一项：第一确定方式为根据发送信道对应的逻辑信道的优先级确定该发送信道的优先级，以及第二确定方式为根据基站指示的优先级确定该发送信道的优先级。
在第一确定方式中，例如，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的信道优先级由PUSCH中发送的媒体接入控制协议数据单元(Medium Access Control Protocol Data Unit，MAC PDU)中包含的最高逻辑信道优先级的逻辑信道的数据决定(如，MAC PDU中包括逻辑信道优先级-1的数据和逻辑信道优先级-2的数据，其中逻辑信道优先级-1高于逻辑信道优先级-2，则发送该MAC PDU的PUSCH的信道优先级为逻辑信道优先级-1)。通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)发送的调度请求(Scheduling Request，SR)的信道优先级由触发该SR发送的逻辑信道的逻辑信道优先级确定(如，逻辑信道优先级-1的逻辑信道-1有新数据到达，触发了SR发送，则发送该SR的PUCCH的信道优先级为信道优先级-1)。
在第二确定方式中，例如，基站通过无线资源控制(Radio Resource Control，RRC)消息为终端指定CG配置项configuredGrantConfig-1，并指示使用该CG配置项configuredGrantConfig-1的资源发送的PUSCH信道的优先级为信道优先级-1(如，基站通过下行控制信息(Downlink Control Information，DCI)调度PUSCH的发送，并通过该DCI指示该调度的PUSCH的发送的优先级为信道优先级-1)。
对于多个发送信道，在根据优先级信息确定各个发送信道的优先级之后，各个发送信道可以按照所确定的优先级进行发送。例如，对于发送信道1、发送信道2和发送信道3，分别确定它们的优先级为优先级1、优先级2和优先级3，如果不同的发送信道由于冲突而无法同时发送，则可以根据所确定的 优先级进行发送。假定优先级1高于优先级2，而优先级2高于优先级3，当然各个优先级的高低可以事先约定而不限于此。例如，当发送信道1和发送信道2发生冲突时，由于发送信道1的优先级1高于发送信道2的优先级2，即发送信道1相对于发送信道2为高优先发送，则将进行发送信道1的发送，而发送信道2的发送被放弃。又例如，当发送信道2和发送信道3发生冲突时，由于发送信道3的优先级3低于发送信道2的优先级2，即发送信道3相对于发送信道2为低优先发送，则将进行发送信道2的发送，而发送信道3的发送被放弃。
在本公开的实施例中，基站同时发送CG配置信息和发送信道的优先级信息，CG配置信息用于在终端根据优先级信息确定发送信道的优先级的情况下，与预置数据重传信息以及发送失败情况决定待采用的数据重传方法，从而提供了能够在同时进行CG配置以及发送信道的优先级配置的情况下进行数据重传的方法，因此具有数据发送的高可靠性以及低时延的优点。
在一些实施例中，所述预置数据重传信息包括以下中的至少一种：当所述CG配置类型为第一CG配置类型且所述发送失败情况为第一发送失败情况或第二发送失败情况时，采用第一数据重传方法；当所述CG配置类型为第一CG配置类型且在未发生第一发送失败情况以及第二发送失败情况的情况下未在上行授权重传定时器超时前收到反馈时，采用第一数据重传方法；以及当所述CG配置类型为第二CG配置类型且所述发送失败情况为第一发送失败情况时，采用第二数据重传方法；其中，所述第一CG配置类型为终端根据所述CG配置信息指示的可用混合自动重传请求HARQ进程数量选择HARQ进程编号和/或冗余版本RV的CG配置类型，所述第二CG配置类型为终端根据所述CG配置信息指示的资源分配时间位置以及可用HARQ进程数量计算HARQ进程编号和/或RV的CG配置类型；所述第一发送失败情况指示频率信道接入失败情况，所述第二发送失败情况指示发送信道根据优先级信息被确定为低优先发送的情况；在所述第一数据重传方法中，用于重传的CG资源与发送失败的CG资源具有相同的可容纳数据大小以及相同的HARQ进程编号，在所述第二数据重传方法中，用于重传的CG资源与发送失败的CG资源由相同的CG配置信息指示且具有相同的HARQ进程编号。
CG配置信息中至少包括资源分配时间位置以及可用HARQ进程数量。其中，资源分配时间位置可以包括：资源分配周期、资源分配起始位置或其他。可选的，CG配置信息还可以包括可用HARQ进程起始编号。如果网络侧提供的CG配置信息中没有提供可用HARQ进程起始编号，则以约定的HARQ进程编号(如，HARQ进程编号0)作为可用HARQ进程起始编号。
在本实施例中，CG配置类型包括CG配置类型1和CG配置类型2中任一种。在CG配置类型1中，通过CG资源发送的数据所采用的HARQ进程编号和/或RV可由终端根据CG配置信息指示的可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据可用HARQ进程数量以及预先约定的HARQ进程编号)自行选择。例如，基站通过为终端配置CG的重传定时器(如，cg-RetransmissionTimer)隐含指示该CG配置类型1。终端在选择1个CG资源-1发送MAC PDU-1的时候，终端可以根据可用HARQ进程起始编号从可用HARQ进程数量中选择HARQ进程-1发送该MAC PDU-1并选择RV0作为HARQ RV，此外，终端在通过PUSCH信道发送该MAC PDU-1的时候向基站指示其使用了HARQ进程-1发送该MAC PDU-1，并可以指示该MAC PDU-1采用的HARQ RV为RV0。在CG配置类型2中，通过CG资源发送的数据所采用的HARQ进程编号根据CG配置信息指示的资源分配时间位置、可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据资源分配时间位置、可用HARQ进程数量以及预先约定的HARQ进程编号)计算得出。例如，终端根据资源分配周期、资源分配起始位置计算出终端可使用的上行发送资源的时域位置，然后通过可用HARQ进程数量以及可用HARQ进程起始编号计算出每个上行发送资源可使用的HARQ进程编号。基站根据在固定时域位置接收到的PUSCH数据，可以确定该PUSCH数据所使用的HARQ进程编号。
在本实施例中，发送失败情况包括发送失败情况1和发送失败情况2中至少一种。在发送失败情况1中，发生频率信道接入失败而导致发送失败。例如，当终端通过PUSCH-1在频率信道-1发送MAC PDU-1时，如果频率信道-1已被占用，则会导致该PUSCH-1发送失败。在发送失败情况2中，发送信道的优先级低而导致发送失败。例如，如果CG资源-1对应的PUSCH-1发送和其他上行信道发送发生冲突，而根据该CG资源-1生成的MAC PDU-1中包含的数据的逻辑信道的优先级较低，则该CG资源-1对应的PUSCH-1信道的优先级低，从而导致该PUSCH-1发送失败。
在本实施例中，数据重传方法包括重传方法1和重传方法2中至少一种。在重传方法1中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源(即，发送失败的上行数据对应的上行CG资源)可以由相同或不同的CG配置信息指示，只要用于重传的数据资源能容纳的数据大小与发送失败的CG资源能容纳的数据大小相同，且用于重传的CG资源所使用的HARQ进程与发送失败的CG资源所使用的HARQ进程相同。例如，基站为终端配置了CG配置项 configuredGrantConfig-1和configuredGrantConfig-2。该两个CG配置项指示的CG资源能容纳相同的数据大小。如果终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送MAC PDU-1导致数据发送失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源，仍通过HARQ进程-1进行数据重传。在重传方法2中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源可以由相同的CG配置信息指示且具有相同的HARQ进程编号。例如，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2。如果终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送MAC PDU-1导致数据发送失败，则终端仅可以选择configuredGrantConfig-1配置项指示的CG资源，仍通过HARQ进程-1进行数据重传。
终端根据不同的CG配置类型和不同的发送失败情况，采用不同的数据重传方法进行数据重传。
对于CG配置类型1，如果先前发送由于发送失败情况1而失败，则终端将采用重传方法1进行数据重传。例如，如图2所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。如图2所示，由于configuredGrantConfig-2指示的CG资源的时间位置距离发送失败的CG资源更近，则终端选择configuredGrantConfig-2指示的CG资源，仍使用HARQ进程-1对MAC PDU-1进行数据重传。
对于CG配置类型1，如果先前发送由于发送失败情况2而失败，则终端将采用重传方法1进行数据重传。例如，如图3所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果根据终端的MAC层确定该上行数据发送的优先级较低，则在发生上行发送冲突时由于发送信道的优先级低而导致该上行数据的发送失败，此时，终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。如图3所示，由于configuredGrantConfig-2指示的CG资源的时间位置距离发送失败的CG资源更近，则终端选择configuredGrantConfig-2指示的CG资源，仍使用HARQ进程-1对MAC PDU-1进行数据重传。
对于CG配置类型2，如果先前发送由于发送失败情况1而失败，则终端将采用重传方法2进行数据重传。例如，如图4所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型2。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端仅可以选择configuredGrantConfig-1配置项指示的CG资源进行数据重传。如图4所示，由于需要仍使用HARQ进程-1对MAC PDU-1进行数据重传，则终端选择configuredGrantConfig-1指示的第三CG资源而非第二CG资源进行数据重传，因为该第二CG资源对应HARQ进程-2而第三CG资源也对应HARQ进程-1。
基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且基站配置了上行授权重传定时器(如，cg-RetransmissionTimer)，终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果根据终端的MAC层确定该上行数据发送的优先级较高且该MAC PDU-1的PUSCH信道的发送并未发生信道接入失败，则在发送该上行数据的同时启动与该HARQ进程-1对应的上行授权重传定时器，如果在该定时器超时之前未收到基站发送的反馈信息，则需要对该MAC PDU-1进行数据重传。此时，终端仅可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源，仍使用HARQ进程-1进行数据重传。
在一些实施例中，当发生第一发送失败情况时，发送信道根据优先级信息被确定为高优先发送。
在本实施例中，终端在确定发送失败情况是第一发送失败情况还是第二发送失败情况时，首先确定发送信道的优先级为低还是高(即，是为高优先发送还是低优先发送)，如果发送信道的优先级为高则进一步确定是否发生频率信道接入失败。
在一些实施例中，用于重传的CG资源的时间位置与发送失败的CG资源的时间位置之间的距离大于或等于数据信道处理时长。
在本实施例中，用于重传的CG资源的时间位置应该为距离发送失败的CG资源的时间位置大于或等于终端进行数据信道处理时长的资源。
如图5所示，基站为终端配置了CG配置项configuredGrantConfig-1。终端使用configuredGrantConfig-1指示的CG资源-1，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的发送发生了发送失败情况，则需要对该MAC PDU-1进行数据重传。若根据预置数据重传信息确定终端可以选择configuredGrantConfig-1配置项指示的CG资源-2、CG资源-3或CG资源-4中任一者进行数据重传，由于CG资源-2的时间位置距离CG资源-1的时间位置过近，如图5所示，如果终端采用CG资源-2，则终端将没有足够处理时间进行数据重传，因此终端仅能从CG资源-3和CG资源-4中选择用于进行数据重传的CG资源。由于CG资源-3的时间位置相比CG资源-4的时间位置更接近发送失败的CG资源，则终端将选择CG资源-3来进行数据重传。
如图6所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。由于configuredGrantConfig-2指示的CG资源-2’的时间位置距离发送失败的CG资源-1的时间位置过近，如果终端采用CG资源-2’，则终端将没有足够处理时间进行数据重传，则终端将选择configuredGrantConfig-1指示的CG资源-2，仍使用HARQ进程-1对MAC PDU-1进行数据重传。
在一些实施例中，所述预置数据重传信息还包括重传次数阈值和/或重传时长阈值，重传次数阈值和/或重传时长阈值与数据重传次数相关。
在本实施例中，当需要进行数据重传时，可以限定数据重传次数。例如，预置数据重传信息可以包括重传次数阈值和/或重传时长阈值来限定数据重传次数。在一示例中，预置数据重传信息针对特定MAC PDU限定的数据重传次数为n次，其中n为大于或等于0的正整数。当终端针对该MAC PDU进行数据重传的次数达到重传次数阈值时，则终端不再针对该MAC PDU进行数据重传。在另一示例中，预置数据重传信息针对特定MAC PDU限定的数据重传时长为Tx。当终端针对该MAC PDU进行数据重传的时间达到数据重传时长Tx时，则终端不再针对该MAC PDU进行数据重传。
在一些实施例中，发送信道可以包括上行数据信道、上行控制信道和上行探测信号信道中的至少一种。
图7示出了根据本公开实施例的一种数据重传确定方法的流程示意图。在本实施例中，方法由基站执行，如图7所示，该数据重传确定方法包括以下步骤：
S701，向终端发送预置数据重传信息。
预置数据重传信息指示数据重传方法、发送失败情况以及CG配置类型之间的对应关系。预置数据重传信息可以为基站与终端预先约定并发送至终端，终端可将预置数据重传信息存储于本地。
S702，向终端发送上行授权CG配置信息和发送信道的优先级信息，CG配置信息用于在终端根据优先级信息确定发送信道的优先级时，与预置数据重传信息以及发送失败情况决定待采用的数据重传方法。其中，CG配置信息包括CG配置类型。
在本实施例中，基站向终端发送的配置信息同时包括指示CG配置类型的CG配置信息和发送信道的优先级信息。终端在接收到CG配置信息和优先级信息并在根据优先级信息确定发送信道的优先级的情况下，根据预置数据重传信息、不同CG配置类型和不同发送失败情况，采用不同数据重传方法。
CG配置信息可以包括一个或多个配置项，例如，对于小区1的带宽部分(Bandwidth Part，BWP)可以配置多个配置项(configuredGrantConfig-1和configuredGrantConfig-2)。每个配置项可以指示CG配置类型。
发送信道的优先级信息用于指示发送信道的优先级的确定方式。由于终端不能同时发送多个上行信息，因此，在多个上行信道的发送发生冲突时，终端选择高优先级的信道进行发送。发送信道的优先级的确定方式包括以下至少一项：第一确定方式为根据发送信道对应的逻辑信道的优先级确定该发送信道的优先级，以及第二确定方式为根据基站指示的优先级确定该发送信道的优先级。
对于多个发送信道，在根据发送信道的优先级信息确定各个发送信道的优先级之后，各个发送信道可以按照所确定的优先级进行发送。例如，对于发送信道1、发送信道2和发送信道3，分别确定它们的优先级为优先级1、优先级2和优先级3，如果不同的发送信道由于冲突而无法同时发送，则可以根据所确定的优先级进行发送。假定优先级1高于优先级2，而优先级2高于优先级3，当然各个优先级的高低可以事先约定而不限于此。例如，当发送信道1和发送信道2发生冲突时，由于发送信道1的优先级1高于发送信道2的优先级2，即发送信道1相对于发送信道2为高优先发送，则将进行发送信道1的发送，而发送信道2的发送被放弃。又例如，当发送信道2和发送信道3发生冲突时，由于发送信 道3的优先级3低于发送信道2的优先级2，即发送信道3相对于发送信道2为低优先发送，则将进行发送信道2的发送，而发送信道3的发送被放弃。
在本公开的实施例中，基站将预置数据重传信息发送至终端，此外，基站同时发送CG配置信息和发送信道的优先级信息，而CG配置信息用于在终端根据优先级信息确定发送信道的优先级的情况下，与预置数据重传信息以及发送失败情况决定待采用的数据重传方法，从而提供了能够在同时进行CG配置以及发送信道的优先级配置的情况下进行数据重传的方法，因此具有数据发送的高可靠性以及低时延的优点。
在一些实施例中，所述预置数据重传信息包括以下中的至少一种：当所述CG配置类型为第一CG配置类型且所述发送失败情况为第一发送失败情况或第二发送失败情况时，采用第一数据重传方法；当所述CG配置类型为第一CG配置类型且在未发生第一发送失败情况以及第二发送失败情况的情况下未在上行授权重传定时器超时前收到反馈时，采用第一数据重传方法；以及当所述CG配置类型为第二CG配置类型且所述发送失败情况为第一发送失败情况时，采用第二数据重传方法；其中，所述第一CG配置类型为终端根据所述CG配置信息指示的可用混合自动重传请求HARQ进程数量选择HARQ进程编号和/或冗余版本RV的CG配置类型，所述第二CG配置类型为终端根据所述CG配置信息指示的资源分配时间位置以及可用HARQ进程数量计算HARQ进程编号和/或RV的CG配置类型；所述第一发送失败情况指示频率信道接入失败情况，所述第二发送失败情况指示发送信道根据优先级信息被确定为低优先发送的情况；在所述第一数据重传方法中，用于重传的CG资源与发送失败的CG资源具有相同的可容纳数据大小以及相同的HARQ进程编号，在所述第二数据重传方法中，用于重传的CG资源与发送失败的CG资源由相同的CG配置信息指示且具有相同的HARQ进程编号。
在本实施例中，CG配置类型包括CG配置类型1和CG配置类型2中任一种。在CG配置类型1中，通过CG资源发送的数据所采用的HARQ进程编号和/或RV可由终端根据CG配置信息指示的可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据可用HARQ进程数量以及预先约定的HARQ进程编号)自行选择。在CG配置类型2中，通过CG资源发送的数据所采用的HARQ进程编号根据CG配置信息指示的资源分配时间位置、可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据资源分配时间位置、可用HARQ进程数量以及预先约定的HARQ进程编号)计算得出。
在本实施例中，发送失败情况包括发送失败情况1和发送失败情况2中至少一种。在发送失败情况1中，发生频率信道接入失败而导致发送失败。在发送失败情况2中，发送信道的优先级低而导致发送失败。
在本实施例中，数据重传方法包括重传方法1和重传方法2中至少一种。在重传方法1中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源(即，发送失败的上行数据对应的上行CG资源)可以由相同或不同的CG配置信息指示，只要用于重传的数据资源能容纳的数据大小与发送失败的CG资源能容纳的数据大小相同，且用于重传的CG资源所使用的HARQ进程与发送失败的CG资源所使用的HARQ进程相同。在重传方法2中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源可以由相同的CG配置信息指示且具有相同的HARQ进程编号。
在本实施例中，终端根据不同的CG配置类型和不同的发送失败情况，采用不同的数据重传方法进行数据重传。当CG配置类型为CG配置类型1且发送失败情况为发送失败情况1或发送失败情况2时，指示采用数据重传方法1；当CG配置类型为CG配置类型1且在未发生发送失败情况1以及发送失败情况2的情况下未在上行授权重传定时器超时前收到反馈时，指示采用数据重传方法1；以及当CG配置类型为CG配置类型2且发送失败情况为发送失败情况1时，指示采用数据重传方法2。
在一些实施例中，当发生第一发送失败情况时，发送信道根据优先级信息被确定为高优先发送。
在一些实施例中，用于重传的CG资源的时间位置与发送失败的CG资源的时间位置之间的距离大于或等于数据信道处理时长。
在本实施例中，用于重传的CG资源的时间位置应该为距离发送失败的CG资源的时间位置大于或等于终端进行数据信道处理时长的资源。
在一些实施例中，所述预置数据重传信息还包括重传次数阈值和/或重传时长阈值，重传次数阈值和/或重传时长阈值与数据重传次数相关。
在一些实施例中，发送信道还可以包括上行数据信道、上行控制信道和上行探测信号信道中的至少一种。
图8示出了根据本公开实施例的一种数据重传确定方法的流程示意图。在本实施例中，方法由终端 执行，如图8所示，该数据重传确定方法包括以下步骤：
S801，接收上行授权CG配置信息和发送信道的优先级信息，其中，CG配置信息包括CG配置类型。
在本实施例中，终端从基站接收的配置信息同时包括指示CG配置类型的CG配置信息和发送信道的优先级信息。
S802，在根据优先级信息确定发送信道的优先级的情况下，基于预置数据重传信息、CG配置信息以及发送失败情况，确定待采用的数据重传方法，其中，预置数据重传信息指示数据重传方法、发送失败情况以及CG配置类型之间的对应关系。
在本实施例中，终端在接收到CG配置信息和发送信道的优先级信息并在根据优先级信息确定发送信道的优先级的情况下，根据预置数据重传信息、不同CG配置类型和不同发送失败情况，采用不同数据重传方法。其中，预置数据重传信息指示了不同CG配置类型、不同发送失败情况以及不同数据重传方法之间的对应关系。预置数据重传信息可以是基站与终端预先约定并预存于终端侧。
CG配置信息可以包括一个或多个配置项，例如，对于小区1的带宽部分(Bandwidth Part，BWP)可以配置多个配置项(configuredGrantConfig-1和configuredGrantConfig-2)。每个配置项可以指示CG配置类型。
发送信道的优先级信息用于指示发送信道的优先级的确定方式。由于终端不能同时发送多个上行信息，因此，在多个上行信道的发送发生冲突时，终端选择高优先级的信道进行发送。发送信道的优先级的确定方式包括以下至少一项：第一确定方式为根据发送信道对应的逻辑信道的优先级确定该发送信道的优先级，以及第二确定方式为根据基站指示的优先级确定该发送信道的优先级。
在第一确定方式中，例如，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的信道优先级由PUSCH中发送的媒体接入控制协议数据单元(Medium Access Control Protocol Data Unit，MAC PDU)中包含的最高逻辑信道优先级的逻辑信道的数据决定(如，MAC PDU中包括逻辑信道优先级-1的数据和逻辑信道优先级-2的数据，其中逻辑信道优先级-1高于逻辑信道优先级-2，则发送该MAC PDU的PUSCH的信道优先级为逻辑信道优先级-1)。通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)发送的调度请求(Scheduling Request，SR)的信道优先级由触发该SR发送的逻辑信道的逻辑信道优先级确定(如，逻辑信道优先级-1的逻辑信道-1有新数据到达，触发了SR发送，则发送该SR的PUCCH的信道优先级为信道优先级-1)。
在第二确定方式中，例如，基站通过无线资源控制(Radio Resource Control，RRC)消息为终端指定CG配置项configuredGrantConfig-1，并指示使用该CG配置项configuredGrantConfig-1的资源发送的PUSCH信道的优先级为信道优先级-1(如，基站通过下行控制信息(Downlink Control Information，DCI)调度PUSCH的发送，并通过该DCI指示该调度的PUSCH的发送的优先级为信道优先级-1)。
对于多个发送信道，在根据发送信道的优先级信息确定各个发送信道的优先级之后，各个发送信道可以按照所确定的优先级进行发送。例如，对于发送信道1、发送信道2和发送信道3，分别确定它们的优先级为优先级1、优先级2和优先级3，如果不同的发送信道由于冲突而无法同时发送，则可以根据所确定的优先级进行发送。假定优先级1高于优先级2，而优先级2高于优先级3，当然各个优先级的高低可以事先约定而不限于此。例如，当发送信道1和发送信道2发生冲突时，由于发送信道1的优先级1高于发送信道2的优先级2，即发送信道1相对于发送信道2为高优先发送，则将进行发送信道1的发送，而发送信道2的发送被放弃。又例如，当发送信道2和发送信道3发生冲突时，由于发送信道3的优先级3低于发送信道2的优先级2，即发送信道3相对于发送信道2为低优先发送，则将进行发送信道2的发送，而发送信道3的发送被放弃。
在本公开的实施例中，终端接收CG配置信息和发送信道的优先级信息，并在根据优先级信息确定发送信道的优先级的情况下，基于预置数据重传信息、CG配置信息以及发送失败情况，确定待采用的数据重传方法，从而提供了能够在同时进行CG配置以及发送信道的优先级配置的情况下进行数据重传的方法，因此具有数据发送的高可靠性以及低时延的优点。
在一些实施例中，所述预置数据重传信息包括以下中的至少一种：当所述CG配置类型为第一CG配置类型且所述发送失败情况为第一发送失败情况或第二发送失败情况时，采用第一数据重传方法；当所述CG配置类型为第一CG配置类型且在未发生第一发送失败情况以及第二发送失败情况的情况下未在上行授权重传定时器超时前收到反馈时，采用第一数据重传方法；以及当所述CG配置类型为第二CG配置类型且所述发送失败情况为第一发送失败情况时，采用第二数据重传方法；其中，所述第一CG配置类型为终端根据所述CG配置信息指示的可用混合自动重传请求HARQ进程数量选择HARQ进程编号和/或冗余版本RV的CG配置类型，所述第二CG配置类型为终端根据所述CG配置信息指示的资源分配时间位置以及可用HARQ进程数量计算HARQ进程编号和/或RV的CG配置类型；所述第 一发送失败情况指示频率信道接入失败情况，所述第二发送失败情况指示发送信道根据优先级信息被确定为低优先发送的情况；在所述第一数据重传方法中，用于重传的CG资源与发送失败的CG资源具有相同的可容纳数据大小以及相同的HARQ进程编号，在所述第二数据重传方法中，用于重传的CG资源与发送失败的CG资源由相同的CG配置信息指示且具有相同的HARQ进程编号。
CG配置信息中至少包括资源分配时间位置以及可用HARQ进程数量。其中，资源分配时间位置可以包括：资源分配周期、资源分配起始位置或其他。可选的，CG配置信息还可以包括可用HARQ进程起始编号。如，网络侧提供的CG配置信息中没有提供可用HARQ进程起始编号，则以约定的HARQ进程编号(如，HARQ进程编号0)作为可用HARQ进程起始编号。
在本实施例中，CG配置类型包括CG配置类型1和CG配置类型2中任一种。在CG配置类型1中，通过CG资源发送的数据所采用的HARQ进程编号和/或RV可由终端根据CG配置信息指示的可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据可用HARQ进程数量以及预先约定的HARQ进程编号)自行选择。例如，基站通过为终端配置CG的重传定时器(如，cg-RetransmissionTimer)隐含指示该CG配置类型1。终端在选择1个CG资源-1发送MAC PDU-1的时候，终端可以根据可用HARQ进程起始编号从可用HARQ进程数量中选择HARQ进程-1发送该MAC PDU-1并选择RV0作为HARQ RV，此外，终端在通过PUSCH信道发送该MAC PDU-1的时候向基站指示其使用了HARQ进程-1发送该MAC PDU-1，并可以指示该MAC PDU-1采用的HARQ RV为RV0。在CG配置类型2中，通过CG资源发送的数据所采用的HARQ进程编号根据CG配置信息指示的资源分配时间位置、可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据资源分配时间位置、可用HARQ进程数量以及预先约定的HARQ进程编号)计算得出。例如，终端根据资源分配周期、资源分配起始位置计算出终端可使用的上行发送资源的时域位置，然后通过可用HARQ进程数量以及可用HARQ进程起始编号计算出每个上行发送资源可使用的HARQ进程编号。基站根据在固定时域位置接收到的PUSCH数据，可以确定该PUSCH数据所使用的HARQ进程编号。
在本实施例中，发送失败情况包括发送失败情况1和发送失败情况2中至少一种。在发送失败情况1中，发生频率信道接入失败而导致发送失败。例如，当终端通过PUSCH-1在频率信道-1发送MAC PDU-1时，如果频率信道-1已被占用，则会导致该PUSCH-1发送失败。在发送失败情况2中，发送信道的优先级低而导致发送失败。例如，如果CG资源-1对应的PUSCH-1发送和其他上行信道发送发生冲突，而根据该CG资源-1生成的MAC PDU-1中包含的数据的逻辑信道的优先级较低，则该CG资源-1对应的PUSCH-1信道的优先级低，从而导致该PUSCH-1发送失败。
在本实施例中，数据重传方法包括重传方法1和重传方法2中至少一种。在重传方法1中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源(即，发送失败的上行数据对应的上行CG资源)可以由相同或不同的CG配置信息指示，只要用于重传的数据资源能容纳的数据大小与发送失败的CG资源能容纳的数据大小相同，且用于重传的CG资源所使用的HARQ进程与发送失败的CG资源所使用的HARQ进程相同。例如，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2。该两个CG配置项指示的CG资源能容纳相同的数据大小。如果终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送MAC PDU-1导致数据发送失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源，仍通过HARQ进程-1进行数据重传。在重传方法2中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源可以由相同的CG配置信息指示且具有相同的HARQ进程编号。例如，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2。如果终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送MAC PDU-1导致数据发送失败，则终端仅可以选择configuredGrantConfig-1配置项指示的CG资源，仍通过HARQ进程-1进行数据重传。
终端根据不同的CG配置类型和不同的发送失败情况，采用不同的数据重传方法进行数据重传。
对于CG配置类型1，如果先前发送由于发送失败情况1而失败，则终端将采用重传方法1进行数据重传。例如，如图2所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。如图2所示，由于configuredGrantConfig-2指示的CG资源的时间位置距离发送失败的CG资源更近，则终端选择configuredGrantConfig-2指示的CG资源，仍使用HARQ进程-1对MAC PDU-1进行数据重 传。
对于CG配置类型1，如果先前发送由于发送失败情况2而失败，则终端将采用重传方法1进行数据重传。例如，如图3所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果根据终端的MAC层确定该上行数据发送的优先级较低，则在发生上行发送冲突时由于发送信道的优先级低而导致该上行数据的发送失败，此时，终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。如图3所示，由于configuredGrantConfig-2指示的CG资源的时间位置距离发送失败的CG资源更近，则终端选择configuredGrantConfig-2指示的CG资源，仍使用HARQ进程-1对MAC PDU-1进行数据重传。
对于CG配置类型2，如果先前发送由于发送失败情况1而失败，则终端将采用重传方法2进行数据重传。例如，如图4所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型2。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端仅可以选择configuredGrantConfig-1配置项指示的CG资源进行数据重传。如图4所示，由于需要仍使用HARQ进程-1对MAC PDU-1进行数据重传，则终端选择configuredGrantConfig-1指示的第三CG资源进行数据重传，因为该第三CG资源也对应HARQ进程-1。
基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且基站配置了上行授权重传定时器(如，cg-RetransmissionTimer)，终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果根据终端的MAC层确定该上行数据发送的优先级较高且该MAC PDU-1的PUSCH信道的发送并未发生信道接入失败，则在发送该上行数据的同时启动与该HARQ进程-1对应的上行授权重传定时器，如果在该定时器超时之前未收到基站发送的反馈信息，则需要对该MAC PDU-1进行数据重传。此时，终端仅可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源，仍使用HARQ进程-1进行数据重传。
在一些实施例中，当发生第一发送失败情况时，发送信道根据优先级信息被确定为高优先发送。
在本实施例中，终端在确定发送失败情况是第一发送失败情况还是第二发送失败情况时，首先确定发送信道的优先级为低还是高(即，是为高优先发送还是低优先发送)，如果发送信道的优先级为高则进一步确定是否发生频率信道接入失败。
在一些实施例中，用于重传的CG资源的时间位置与发送失败的CG资源的时间位置之间的距离大于或等于数据信道处理时长。
在本实施例中，用于重传的CG资源的时间位置应该为距离发送失败的CG资源的时间位置大于或等于终端进行数据信道处理时长的资源。
如图5所示，基站为终端配置了CG配置项configuredGrantConfig-1。终端使用configuredGrantConfig-1指示的CG资源-1，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的发送发生了发送失败情况，则需要对该MAC PDU-1进行数据重传。若根据预置数据重传信息确定终端可以选择configuredGrantConfig-1配置项指示的CG资源-2、CG资源-3或CG资源-4中任一者进行数据重传，由于CG资源-2的时间位置距离CG资源-1的时间位置过近，如图5所示，如果终端采用CG资源-2，则终端将没有足够处理时间进行数据重传，因此终端仅能从CG资源-3和CG资源-4中选择用于进行数据重传的CG资源。由于CG资源-3的时间位置相比CG资源-4的时间位置更接近发送失败的CG资源，则终端将选择CG资源-3来进行数据重传。
如图6所示，基站为终端配置了CG配置项configuredGrantConfig-1和configuredGrantConfig-2，该两个配置项均指示CG配置类型1，且该两个配置项指示的CG资源能容纳的数据大小相同。终端使用configuredGrantConfig-1指示的CG资源，通过HARQ进程-1发送上行数据MAC PDU-1，如果该MAC PDU-1的PUSCH信道的发送发生了信道接入失败，则终端可以选择configuredGrantConfig-1和configuredGrantConfig-2配置项中任一配置项指示的CG资源进行数据重传。由于configuredGrantConfig-2指示的CG资源-2’的时间位置距离发送失败的CG资源-1的时间位置过近，如果终端采用CG资源-2’，则终端将没有足够处理时间进行数据重传，则终端将选择configuredGrantConfig-1指示的CG资源-3，仍使用HARQ进程-1对MAC PDU-1进行数据重传。
在一些实施例中，所述预置数据重传信息还包括重传次数阈值和/或重传时长阈值，重传次数阈值和/或重传时长阈值与数据重传次数相关。
在本实施例中，当需要进行数据重传时，可以限定数据重传次数。例如，预置数据重传信息可以包 括重传次数阈值和/或重传时长阈值来限定数据重传次数。在一示例中，预置数据重传信息针对特定MAC PDU限定的数据重传次数为n次，其中n为大于或等于0的正整数。当终端针对该MAC PDU进行数据重传的次数达到重传次数阈值时，则终端不再针对该MAC PDU进行数据重传。在另一示例中，预置数据重传信息针对特定MAC PDU限定的数据重传时长为Tx。当终端针对该MAC PDU进行数据重传的时间达到数据重传时长Tx时，则终端不再针对该MAC PDU进行数据重传。
在一些实施例中，发送信道还可以包括上行数据信道、上行控制信道和上行探测信号信道中的至少一种。
图9示出了根据本公开实施例的一种数据重传确定方法的流程示意图。在本实施例中，方法由终端执行，如图9所示，该数据重传确定方法包括以下步骤：
S901，接收预置数据重传信息。
预置数据重传信息指示数据重传方法、发送失败情况以及CG配置类型之间的对应关系。终端接收到预置数据重传信息后可将预置数据重传信息存储于本地。
S902，接收上行授权CG配置信息和发送信道的优先级信息，其中，CG配置信息包括CG配置类型。
在本实施例中，终端从基站接收的配置信息同时包括指示CG配置类型的CG配置信息和发送信道的优先级信息。
S903，在根据优先级信息确定发送信道的优先级的情况下，基于预置数据重传信息、CG配置信息以及发送失败情况，确定待采用的数据重传方法。
在本实施例中，终端在接收到CG配置信息和发送信道的优先级信息并在根据优先级信息确定发送信道的优先级的情况下，根据预置数据重传信息、不同CG配置类型和不同发送失败情况，采用不同数据重传方法。
CG配置信息可以包括一个或多个配置项，例如，对于小区1的带宽部分(Bandwidth Part，BWP)可以配置多个配置项(configuredGrantConfig-1和configuredGrantConfig-2)。每个配置项可以指示CG配置类型。
发送信道的优先级信息用于指示发送信道的优先级的确定方式。由于终端不能同时发送多个上行信息，因此，在多个上行信道的发送发生冲突时，终端选择高优先级的信道进行发送。发送信道的优先级的确定方式包括以下至少一项：第一确定方式为根据发送信道对应的逻辑信道的优先级确定该发送信道的优先级，以及第二确定方式为根据基站指示的优先级确定该发送信道的优先级。
对于多个发送信道，在根据发送信道的优先级信息确定各个发送信道的优先级之后，各个发送信道可以按照所确定的优先级进行发送。例如，对于发送信道1、发送信道2和发送信道3，分别确定它们的优先级为优先级1、优先级2和优先级3，如果不同的发送信道由于冲突而无法同时发送，则可以根据所确定的优先级进行发送。假定优先级1高于优先级2，而优先级2高于优先级3，当然各个优先级的高低可以事先约定而不限于此。例如，当发送信道1和发送信道2发生冲突时，由于发送信道1的优先级1高于发送信道2的优先级2，即发送信道1相对于发送信道2为高优先发送，则将进行发送信道1的发送，而发送信道2的发送被放弃。又例如，当发送信道2和发送信道3发生冲突时，由于发送信道3的优先级3低于发送信道2的优先级2，即发送信道3相对于发送信道2为低优先发送，则将进行发送信道2的发送，而发送信道3的发送被放弃。
在本公开的实施例中，终端从基站接收预置数据重传信息，此外，终端还接收CG配置信息和发送信道的优先级信息并在根据优先级信息确定发送信道的优先级的情况下，基于预置数据重传信息、CG配置信息以及发送失败情况，确定待采用的数据重传方法，从而提供了能够在同时进行CG配置以及发送信道的优先级配置的情况下进行数据重传的方法，因此具有数据发送的高可靠性以及低时延的优点。
在一些实施例中，所述预置数据重传信息包括以下中的至少一种：当所述CG配置类型为第一CG配置类型且所述发送失败情况为第一发送失败情况或第二发送失败情况时，采用第一数据重传方法；当所述CG配置类型为第一CG配置类型且在未发生第一发送失败情况以及第二发送失败情况的情况下未在上行授权重传定时器超时前收到反馈时，采用第一数据重传方法；以及当所述CG配置类型为第二CG配置类型且所述发送失败情况为第一发送失败情况时，采用第二数据重传方法；其中，所述第一CG配置类型为终端根据所述CG配置信息指示的可用混合自动重传请求HARQ进程数量选择HARQ进程编号和/或冗余版本RV的CG配置类型，所述第二CG配置类型为终端根据所述CG配置信息指示的资源分配时间位置以及可用HARQ进程数量计算HARQ进程编号和/或RV的CG配置类型；所述第一发送失败情况指示频率信道接入失败情况，所述第二发送失败情况指示发送信道根据优先级信息被确定为低优先发送的情况；在所述第一数据重传方法中，用于重传的CG资源与发送失败的CG资源具有 相同的可容纳数据大小以及相同的HARQ进程编号，在所述第二数据重传方法中，用于重传的CG资源与发送失败的CG资源由相同的CG配置信息指示且具有相同的HARQ进程编号。
在本实施例中，CG配置类型包括CG配置类型1和CG配置类型2中任一种。在CG配置类型1中，通过CG资源发送的数据所采用的HARQ进程编号和/或RV可由终端根据CG配置信息指示的可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据可用HARQ进程数量以及预先约定的HARQ进程编号)自行选择。在CG配置类型2中，通过CG资源发送的数据所采用的HARQ进程编号根据CG配置信息指示的资源分配时间位置、可用HARQ进程数量以及可用HARQ进程起始编号(在CG配置信息未指示可用HARQ进程起始编号时，根据资源分配时间位置、可用HARQ进程数量以及预先约定的HARQ进程编号)计算得出。
在本实施例中，发送失败情况包括发送失败情况1和发送失败情况2中至少一种。在发送失败情况1中，发生频率信道接入失败而导致发送失败。在发送失败情况2中，发送信道的优先级低而导致发送失败。
在本实施例中，数据重传方法包括重传方法1和重传方法2中至少一种。在重传方法1中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源(即，发送失败的上行数据对应的上行CG资源)可以由相同或不同的CG配置信息指示，只要用于重传的数据资源能容纳的数据大小与发送失败的CG资源能容纳的数据大小相同，且用于重传的CG资源所使用的HARQ进程与发送失败的CG资源所使用的HARQ进程相同。在重传方法2中，对于发送失败的上行数据，终端使用CG资源进行重传，用于重传的数据资源和发送失败的CG资源可以由相同的CG配置信息指示且具有相同的HARQ进程编号。
在本实施例中，终端根据不同的CG配置类型和不同的发送失败情况，采用不同的数据重传方法进行数据重传。当CG配置类型为CG配置类型1且发送失败情况为发送失败情况1或发送失败情况2时，指示采用数据重传方法1；当CG配置类型为CG配置类型1且在未发生发送失败情况1以及发送失败情况2的情况下未在上行授权重传定时器超时前收到反馈时，指示采用数据重传方法1；以及当CG配置类型为CG配置类型2且发送失败情况为发送失败情况1时，指示采用数据重传方法2。
在一些实施例中，当发生第一发送失败情况时，发送信道根据优先级信息被确定为高优先发送。
在一些实施例中，用于重传的CG资源的时间位置与发送失败的CG资源的时间位置之间的距离大于或等于数据信道处理时长。
在本实施例中，用于重传的CG资源的时间位置应该为距离发送失败的CG资源的时间位置大于或等于终端进行数据信道处理时长的资源。
在一些实施例中，所述预置数据重传信息还包括重传次数阈值和/或重传时长阈值，重传次数阈值和/或重传时长阈值与数据重传次数相关。
在一些实施例中，发送信道还可以包括上行数据信道、上行控制信道和上行探测信号信道中的至少一种。
与上述几种实施例提供的数据重传确定方法相对应，本公开还提供一种数据重传确定设备，由于本公开实施例提供的数据重传确定设备与上述几种实施例提供的数据重传确定方法相对应，因此数据重传确定方法的实施方式也适用于本实施例提供的数据重传确定设备，在本实施例中不再详细描述。

其中，CG配置信息包括CG配置类型，所述预置数据重传信息指示数据重传方法、发送失败情况以及CG配置类型之间的对应关系。
