为了更好地理解本公开任一个实施例所描述的技术方案,首先,对在终端与基站之间进行数据传输的应用场景进行说明。
在一个实施例中,当终端处于空闲态或者非激活态时,可以通过以下之一的传输方式将数据发送给基站:
通过初始接入的4步随机接入过程的第三消息(Msg3)发送数据;
通过初始接入的2步随机接入过程的A消息(MsgA)发送数据;

在一个实施例中,专属PUSCH资源,包括:配置授权(CG,Configure Grant)资源和/或预先配置的上行资源(PUR,Preallocated Uplink Resource)。
在一个实施例中,当终端处于空闲态或者非激活态时,基站可以通过以下之一的方式将数据发送给终端:
通过初始接入的4步随机接入过程的第四消息(Msg4)发送数据;
通过初始接入的2步随机接入过程的B消息(MsgB)发送数据;
在基站配置的专属PUSCH资源对应的下行反馈资源上发送数据。
在一个实施例中,当终端在基站配置的专属PUSCH资源上发送数据后,终端会在第一时间范围内接收基站的反馈信息。
在一个实施例中,响应于在第一时间范围内终端没有接收到基站的反馈信息,则终端确定发送上行数据失败;响应于在第一时间范围内终端接收到基站的反馈信息,则终端确定发送上行数据成功。
在一个实施例中,在高速传输数据时,通过混合自动重传请求(HARQ,Hybrid Automatic Repeat reQuest)提升数据传输的可靠性。
在一个实施例中,在基于HARQ的传输数据过程中,发送端发送数据,接收端对接收到的数据进行译码并进行循环冗余(CRC,Cyclic Redundancy Check)校验。若校验正确,则接收端返回确认字符(ACK,Acknowledge Character),发送端发送新的数据;若校验错误,则接收端返回否定确认字符(NACK,Negative ACK),发送端重传该数据。
在一个实施例中,响应于发送端接收到ACK,确定接收端已正确接收数据。
在一个实施例中,响应于确定接收端已经正确接收数据,发送端会删除该数据的相关信息并发送新的数据。
在一个实施例中,响应于发送端接收到NACK,确定接收端未能正确接收该数据,发送端会进行数据的重传。
在一个实施例中,响应于数据的重传次数小于设置的重传次数,重传该数据;响应于数据的重传次数大于设置的重传次数,停止重传数据并发送新的数据。
在一个实施例中,基站通过信令给终端配置半静态的上行数据信道发送资源。这里,信令可以是无线资源控制(RRC,Radio Resource Control)信令、媒体接入控制(MAC,Media Access Control)信令或者下行控制信息(DCI,Downlink Control Information)信令。

在一个实施例中,终端根据资源分配周期和资源分配起始位置可以确定出可以使用的上行数据信道发送资源位置。
在一个实施例中,终端可以通过可以使用的HARQ进程总数量和可以使用的HARQ进程的起始编号确定出每个上行数据信道发送资源对应的可以使用的HARQ进程编号。
如图2所示,本实施例中提供一种传输数据的方法,其中,应用于终端,该方法,包括:
步骤21、响应于确定在非连接态下的上行数据发送失败,在配置的重传资源上重传上行数据;
其中,非连接态,包括:空闲态或者非激活态。
在一个实施例中,可以是终端向基站发送上行数据。
在一些实施例中,终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU,Road Side Unit)、智能家居终端和工业用传感设备等终端。
该基站为终端接入网络的接口设备。
在一些实施例中,基站可以为各种类型的基站,例如,第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中,重传上行数据可以是重复传输相同的上行数据。例如,终端向基站重复传输A数据。
在一个实施例中,重复传输相同上行数据的次数为重传次数。例如,终端向基站发送A数据失败后,重复3次传输A数据,则重传次数为3次。
在一个实施例中,终端重复传输上行数据的次数不大于重传次数。
这里,重复传输相同的上行数据可以增加基站成功接收终端发送该上行数据的概率,能够减少数据发送不成功导致的上行数据丢失的情况,提升了上行数据传输的可靠性。
在一个实施例中,响应于终端在空闲态下发送数据且上行数据发送失败,在空闲态下在配置的重传资源上重传上行数据。
在一个实施例中,响应于终端在非激活态下发送数据且上行数据发送失败,在非激活态下在配置的重传资源上重传上行数据。
在一个实施例中,在非连接态下,终端向基站发送上行数据的方式,包括以下之一:

终端通过初始接入的2步随机接入过程的MsgA将上行数据发送给基站;
终端在基站配置的专属PUSCH资源上将上行数据发送给基站。
在一个实施例中,专属PUSCH资源,包括:CG资源和/或PUR。
在一个实施例中,可以是利用HARQ进程发送或者重传上行数据。
在一个实施例中,终端接收基站通过信令给终端配置的发送或者重传上行数据的资源配置信息。这里,信令可以是无线资源控制(RRC,Radio Resource Control)信令、媒体接入控制(MAC,Media Access Control)信令或者下行控制信息(DCI,Downlink Control Information)信令。
在一个实施例中,该资源配置信息包括以下至少之一:
专属上行资源的分配周期;
专属上行资源的分配起始位置;其中,分配起始位置包括:时域位置和/或频域位置;
配置的HARQ进程的总数量;
配置的HARQ进程的起始编号。
在一个实施例中,终端根据专属上行资源的分配周期和专属上行资源的分配起始位置确定出发送或者重传上行数据的资源位置。
这样,终端可以在该资源位置上发送或者重传上行数据。
在一个实施例中,重传资源为对应于发送上行数据失败使用的HARQ进程的资源。
在一个实施例中,重传资源为配置的多个HARQ进程中的任一HARQ进程的资源。
在一个实施例中,重传资源为配置的未被使用的HARQ进程中的任一HARQ进程的资源。
在一个实施例中,重传资源为对应于发送上行数据失败使用的资源对应的资源配置指示的资源。

在一个实施例中,重传资源为多套资源配置中的任一资源配置指示的资源。
在一个实施例中,终端可以通过配置的HARQ进程的总数量和配置的HARQ进程的起始编号确定出每个上行数据信道发送资源对应的可以使用的HARQ进程编号。
这样,可以利用该HARQ进程发送或者重传上行数据。
在一个实施例中,配置的重传资源可以是在连接态下基站发送给终端的配置信息指示的。
在一个实施例中,在终端重传上行数据之前,接收指示配置的重传资源的配置信息。
在一个实施例中,响应于在发送上行数据后的第一时长内未接收到基站针对上行数据发送的反馈信息,确定向基站发送上行数据失败;或者,响应于在发送上行数据后的第一时长内接收到基站针对上行数据发送的反馈信息,确定向基站发送上行数据成功。
在一个实施例中,第一时长可以是预先配置的时长。
在一个实施例中,第一时长也可以是根据传输场景实时确定的时长。
例如,实时传输场景要求的时延要求大于质量阈值,可以实时设置第一时长为A。
在一个实施例中,响应于接收到基站发送的指示上行数据发送失败的反馈信息,确定向基站发送上行数据失败;或者,响应于接收到基站发送的指示上行数据发送成功的反馈信息,确定向基站发送上行数据成功。
在一个实施例中,配置的重传资源可以是重传之前预先设置的重传资源。
在一个实施例中,配置的重传资源可以是根据传输场景实时设置的重传资源。
例如,实时传输场景要求的服务质量Qos要求大于质量阈值,可以实时设置重传资源为第一资源。
本公开实施例中,响应于确定在非连接态下的上行数据发送失败,在配置的重传资源上重传上行数据。如此,当终端在非连接状态下发送上行数据失败时,可以在配置的重传资源上重传上行数据,相较于在非连接状态下发送上行数据失败时不能重传上行数据的方式,能够提升基站成功接收上行数据的概率,减少上行数据丢失的情况,提升了终端在非连接状态下发送上行数据的可靠性。

在一个实施例中,第一缓存也可以是根据传输场景实时确定的缓存。
例如,实时传输场景要求的缓存数量为A,可以实时设置缓存的数量为A。
在一个实施例中,终端将需要发送的上行数据缓存在第一缓存中。
在一个实施例中,响应于终端每次需要发送或者重传数据,从该第一缓存中取出该上行数据后再通过选定的HARQ进程发送上行数据。
这里,由于第一缓存独立于HARQ进程的缓存,无需从HARQ进程的缓存中获取需要重传的数据,因此,不需要经过HARQ进程的解码,可以直接获取到需要重传的原数据,可以减少重传的时延。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图16所示,本实施例中提供一种传输数据的方法,其中,应用于基站,该方法,包括:
步骤16、在连接态下,向终端发送资源配置信息;
其中,资源配置信息,用于供终端确定在非连接态下发送上行数据失败时确定重传上行数据的重传资源。
在一个实施例中,可以是终端向基站发送上行数据。
在一些实施例中,终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU,Road Side Unit)、智能家居终端和工业用传感设备等终端。
该基站为终端接入网络的接口设备。
在一些实施例中,基站可以为各种类型的基站,例如,第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中,重传上行数据可以是重复传输相同的上行数据。例如,终端向基站重复传输A数据。
在一个实施例中,重复传输相同上行数据的次数为重传次数。例如,终端向基站发送A数据失败后,重复3次传输A数据,则重传次数为3次。
这里,重复传输相同的上行数据可以增加基站成功接收终端发送该上行数据的概率,能够减少数据发送不成功导致的上行数据丢失的情况,提升了上行数据传输的可靠性。
在一个实施例中,响应于终端在空闲态下发送数据且上行数据发送失败,在空闲态下在配置的重传资源上重传上行数据。
在一个实施例中,响应于终端在非激活态下发送数据且上行数据发送失败,在非激活态下在配置的重传资源上重传上行数据。
在一个实施例中,在非连接态下,终端向基站发送上行数据的方式,包括以下之一:
终端通过初始接入的4步随机接入过程的Msg3将上行数据发送给基站;
终端通过初始接入的2步随机接入过程的MsgA将上行数据发送给基站;
终端在基站配置的专属PUSCH资源上将上行数据发送给基站。
在一个实施例中,专属PUSCH资源,包括:CG资源和/或PUR。
在一个实施例中,可以是利用HARQ进程发送或者重传上行数据。
在一个实施例中,终端接收基站通过信令给终端配置的发送或者重传上行数据的资源配置信息。这里,信令可以是无线资源控制(RRC,Radio Resource Control)信令、媒体接入控制(MAC,Media Access Control)信令或者下行控制信息(DCI,Downlink Control Information)信令。
在一个实施例中,该资源配置信息,包括以下至少之一:
专属上行资源的分配周期;
专属上行资源的分配起始位置;其中,分配起始位置包括:时域位置和/或频域位置;
配置的HARQ进程的总数量;
配置的HARQ进程的起始编号。
在一个实施例中,终端根据专属上行资源的分配周期和专属上行资源的分配起始位置确定出发送或者重传上行数据的资源位置。
这样,终端可以在该资源位置上发送或者重传上行数据。
在一个实施例中,重传资源为对应于发送上行数据失败使用的HARQ进程的资源。
在一个实施例中,重传资源为配置的多个HARQ进程中的任一HARQ进程的资源。
在一个实施例中,重传资源为配置的未被使用的HARQ进程中的任一HARQ进程的资源。
在一个实施例中,重传资源为对应于发送上行数据失败使用的资源对应的资源配置指示的资源。
在一个实施例中,重传资源为多套资源配置中的备选资源配置指示的资源;其中,备选资源配置指示的资源可发送的数据量与对应于发送上行数据失败使用的资源可发送的数据量相同。
在一个实施例中,重传资源为多套资源配置中的任一资源配置指示的资源。
在一个实施例中,终端可以通过配置的混合自动重传请求HARQ进程的总数量和配置的HARQ进程的起始编号确定出每个上行数据信道发送资源对应的可以使用的HARQ进程编号。
这样,可以利用该HARQ进程发送或者重传上行数据。
在一个实施例中,配置的重传资源可以是在连接态下基站发送给终端的配置信息指示的。
在一个实施例中,在终端重传上行数据之前,接收指示配置的重传资源的配置信息。
在一个实施例中,响应于在发送上行数据后的第一时长内未接收到基站针对上行数据发送的反馈信息,确定向基站发送上行数据失败。
在一个实施例中,第一时长可以是预先配置的时长。
在一个实施例中,第一时长也可以是根据传输场景实时确定的时长。
例如,实时传输场景要求的时延要求大于质量阈值,可以实时设置第一时长为A。
在一个实施例中,响应于接收到基站发送的指示上行数据发送失败的反馈信息,确定向基站发送上行数据失败。
在一个实施例中,配置的重传资源可以是重传之前预先设置的重传资源。
在一个实施例中,配置的重传资源可以是根据传输场景实时设置的重传资源。
例如,实时传输场景要求的服务质量Qos要求大于质量阈值,可以实时设置重传资源为第一资源。
本公开实施例中,响应于确定在非连接态下的上行数据发送失败,在配置的重传资源上重传上行数据。如此,当终端在非连接状态下发送上行数据失败时,可以在配置的重传资源上重传上行数据,相较于在非连接状态下发送上行数据失败时不能重传上行数据的方式,能够提升基站成功接收上行数据的概率,减少上行数据丢失的情况,提升了终端在非连接状态下发送上行数据的可靠性。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图17所示,本实施例中提供一种传输数据的方法,其中,应用于基站,该方法,包括:
步骤17、向终端发送重传配置信息;
其中,重传配置信息,至少供终端确定重传上行数据的次数阈值。
在一个实施例中,可以是根据数据传输的要求时延确定次数阈值。
在一个实施例中,响应于数据传输的要求时延大于时延阈值,确定次数阈值大于A;响应于数据传输的要求时延小于时延阈值,确定次数阈值小于A。如此,时延阈值可以适应于数据传输的要求时延。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
为了进一步对本公开任一实施例的理解,通过一个示例性实施例对本公开方案进行进一步说明:
示例1
请参见图18,本实施例中提供一种传输数据的方法,其中,该方法,包括:
步骤a、基站给终端发送1套或多套专属上行资源配置。例如,cg-Config-1和cg-Config-2。
其中,该专属上行资源配置用于空闲态或非激活态的终端进行上行数据的发送。
这里,基站可以给终端发送该专属上行资源的重传配置信息。这里,该专属上行资源配置可以是通过资源配置信息发送的。
其中,该重传配置信息包括以下至少一的信息:
重传次数;
总传输次数(例如,总传输次数为4,则重传次数为3)
这里,重传次数可以是次数阈值。
步骤b、根据步骤a的专属上行资源配置,终端触发在该专属上行资源配置的资源上发送上行数据后,终端在配置的时间范围内等待接收基站发送的反馈信息。
这里,请参见图19,可以是终端在cg-Config-1指示的专属上行资源上通过HARQ进程-1发送上行数据,然后,终端启动定时器(如,feedbackWindow定时器),在该定时器运行期间,终端接收基站的反馈信息。
步骤c、终端在定时器运行期间没有接收到反馈信息,终端确定上行数据发送失败,则终端进行数据重传。
这里,请再次参见图19,终端在反馈窗口(feedbackWindow)之后重发该HARQ-1进程中的数据,例如,Retx-Data)。
