Description

数据传输方法及装置 技术领域
本公开涉及通信领域，尤其涉及数据传输方法及装置。
背景技术
传统的LTE(Long Term Evolution，长期演进)的数据传输流程可以如图1A所示，用户端需要先完成随机接入过程，得到基站授权后，才可以将上行数据发送给基站。但是在NR(New Radio，新空口)系统的物联网的场景中，随机接入过程会带来巨大的信令开销。因此，可以采用免授权的方式，不需要进行随机接入核接收上行授权，用户端自动在预留资源上按照预设方式传输上行数据，如图1B所示。从而减少信令开销，避免功率浪费。
考虑到大多数物联网用户端的业务是周期性的上报的，比如电表，水表等每隔一段时间进行业务数据的上报，因此在免授权上行调度中配置的预留资源也是周期性出现的。
在传统的LTE系统的上行传输中，为了保持来自不同用户端的数据同时到达基站，从而保持数据间的正交性，减少干扰，用户端会按照基站所配置的TA(Timing Advance，传输时间提前量)提前发送数据。一般情况下，初始的TA是基站在随机接入过程中，根据用户端所发送的随机接入前导码确定的，并在RAR(Random Access Response，随机接入响应)消息中发送给用户端。当用户接入网络后，由于无线环境的变化或者用户位置的移动可能会导致原来配置的TA无法满足条件，此时需要再次通过随机接入过程更新TA。
在非授权调度过程中，用户端会首先使用当前存储的TA，并验证此时存储的TA是否还有效。如果当前的TA已经失效，此时用户端需要启动随机接入过程，来重新获得新的TA。
相关技术中，如果用户端的当前的TA已经失效，但是基站仍会为所述用户端保留预留资源，造成资源的浪费。

下面先从用户端侧介绍本公开实施例提供的数据传输方法。
本公开实施例提供了一种数据传输方法，可以用于用户端。参照图2所示，图2是根据一示例性实施例示出的一种数据传输方法流程图，可以包括以下步骤：
在步骤101中，在目标时间单元对当前的传输时间提前量TA进行检测，获得检测结果；
其中，所述目标时间单元是在第一目标资源所对应的第一个时间单元之前的任一个时间单元，所述第一目标资源是与第二目标资源关联的满足指定条件的一个随机接入资源单元，所述第二目标资源是基站预先分配 给所述用户端用于进行免授权数据上报的资源集合中的任一资源单元；
在步骤102中，如果所述检测结果指示当前的TA已经失效，则发送随机接入信号和目标通知消息中的至少一项到所述基站；
其中，所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，以及指示所述基站不再为所述用户端预留所述第三目标资源；或所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，所述目标通知消息用于指示所述基站不再为所述用户端预留第三目标资源；所述第三目标资源至少包括所述第二目标资源。
上述实施例中，可以让用户端提前检测当前的TA是否失效，在当前的TA已经失效时，由基站为所述用户端配置新的TA，且让基站不再为所述用户端保留第三目标资源，节省了物联网中的资源。
针对上述步骤101，先介绍一下第二目标资源，所述第二目标资源则是基站预先分配给所述用户端用于进行免授权数据上报的资源集合中的任一资源单元，例如图3A所示。
而第一目标资源则是与第二目标资源关联的满足指定条件的用于进行随机接入的随机接入资源。其中，可以由用户端直接获取协议中预定义的指定条件，或者可以由基站为用户端配置所述指定条件，用户端接收所述基站通过预设信令，例如RRC信令发送的所述预设条件即可。
在本公开实施例中，所述预设条件可以包括：所述第一目标资源所在的时间单元位于所述第二目标资源所在的时间单元之前，且目标差值最小。其中，所述目标差值是所述第一目标资源所在的时间单元的时间单元编号与所述第二目标资源所在的时间单元的时间单元编号之间的差值。
例如，第二目标资源所在的时间单元是第7个子帧，随机接入资源设置在第2、4、6个子帧上，则用户端可以将第6个子帧所对应的资源单元作为所述第一目标资源，如图3B所示。
或者，所述指定条件可以包括：所述第一目标资源所在的时间单元位于所述第二目标资源所在的时间单元之前，且目标差值大于等于预设值 且所述目标差值最小。
例如，第二目标资源所在的时间单元是第7个子帧，随机接入资源设置在第2、4、6个子帧上，预设值为2，则用户端可以将第4个子帧所对应的资源单元作为所述第一目标资源，如图3C所示。
本公开实施例中，用户端需要在目标时间单元对当前的TA进行测量，即在上述第一目标资源所在的时间单元之前的任一个时间单元对当前的TA进行检测，确定当前的TA是否有效。
可选地，用户端可以测量当前的RSRP(Reference Signal Receiving Power，参考信号接收功率)的值，如果当前的RSRP的值与上次成功传输数据时测量到的RSRP的值的差值小于预设门限值，则可以确定当前的TA仍有效，否则确定当前的TA已经失效。
针对上述步骤102，如果用户端确定当前的TA已经失效，则在第一种情况下，用户端可以只发送随机接入信号到基站，让基站根据随机接入信号重新为所述用户端配置新的TA，并不再为所述用户端预留所述第三目标资源。
如果用户端确定当前的TA已经失效，在第二种情况下，用户端可以发送随机接入信号和目标通知消息到基站，让基站根据随机接入信号，重新为所述用户端配置新的TA，以及根据所述目标通知消息，不再为所述用户端预留所述第三目标资源。
下面分别介绍一下上述两种情况。
在第一种情况下，所述随机接入信号可以同时指示基站需要重新为所述用户端配置新的TA以及不再为所述用户端预留所述第三目标资源。可选地，此时所述随机接入信号可以是所述基站预先分配给所述用户端的第一指定随机接入前导码。
相应地，步骤102可以具体为：
通过所述第一目标资源发送第一随机接入信令到所述基站，所述第一随机接入信令中包括所述第一指定随机接入前导码。
本步骤中，基站侧会在第一目标资源上检测是否接收到用户端通过第一随机接入信令，例如msg.1信令发送的第一指定随机前导码。如果在第一目标资源上检测到用户端通过第一随机接入信令发送的第一指定随机前导码，则基站会重新为所述用户端配置新的TA，且所述基站还会不再为所述用户端预留所述第三目标资源。
在第二种情况下，所述随机接入信号只用于指示所述基站需要重新为所述用户端配置新的TA，所述目标通知消息用于指示所述基站不再为所述用户端预留第三目标资源。可选地，此时所述随机接入信号可以是所述基站预先分配给所述用户端的第二指定随机接入前导码，所述目标通知消息可以是预设标识信息。其中，所述预设标识信可以是所述基站预先分配给所述用户端的一个小区无线网络标识信息，例如C-RNTI(Cell Radio Network Tempory Identity，小区无线网络标识)。
相应地，步骤102可以具体为：
通过所述第一目标资源发送第一随机接入信令到所述基站，所述第一随机接入信令中包括所述第一指定随机接入前导码；
通过第四目标资源发送第二随机接入信令到所述基站，所述第二随机接入信令中包括所述预设标识信息；所述第四目标资源是由所述基站在与所述用户端进行随机接入的过程中为所述用户端分配的用于承载所述第二随机接入信令的资源。
此时，基站侧会在第一目标资源上检测是否接收到用户端通过第一随机接入信令，例如msg.1信令发送的第一指定随机前导码，如果在第一目标资源上，检测到用户端通过第一随机接入信令发送的第二指定随机前导码，则基站会重新为所述用户端配置新的TA。另外，所述基站会在第四目标资源上检测是否接收到用户端通过第二随机接入信令，例如msg.3信令发送的所述预设标识信息，如果基站在第四目标资源上检测到用户端通过第二随机接入信令发送的所述预设标识信息，则所述基站不再为所述用户端预留所述第三目标资源。
本公开实施例中，所述第三目标资源至少包括了所述第二目标资源。
上述实施例中，用户端在目标时间单元就对当前的TA进行检测，实现了提取对当前的TA进行检测的目的。另外，用户端会发送随机接入信号和目标通知消息中的至少一项到所述基站，让基站为自身重新配置新的TA，并通知基站不再为所述用户端预留所述第三目标资源，节省了物理网资源。
在一实施例中，用户端当前有目标数据需要发送给基站，但是由于基站不再为所述用户端预留所述第三目标资源，则用户端需要采用其他方式发送目标数据。
可选地，所述用户端可以在第二随机接入信令，例如msg.3中携带所述目标数据，通过第二随机接入信令将msg.3中原本需要携带的随机接入数据和所述目标数据一起发送给所述基站。
上述实施例中，用户端可以在发送第二随机接入信令到基站时，在第二随机接入信令中携带目标数据，从而可以在与基站进行随机接入的过程中，就将当前需要上报给所述基站的目标数据发送给所述基站。
在一实施例中，用户端当前有目标数据需要发送给基站，则参照4所示，图4是根据图2所示的实施例示出的另一种数据传输方法流程图，上述方法还可以包括以下步骤：
在步骤103中，获取第五目标资源；所述第五目标资源是所述用户端与所述基站完成随机接入过程之后，由所述基站为所述用户端重新分配的用于数据上报的资源；
本公开实施例中，可以由基站在与所述用户端完成随机接入过程之后，为所述用户端重新分配用于数据上报的第五目标资源，相应地，本步骤中，用户端可以在完成随机接入过程之后，获取所述第五目标资源。
在步骤104中，基于所述新的TA，通过所述第五目标资源将目标数据发送给所述基站；所述目标数据是所述用户端当前需要上报给所述基站的数据。
本步骤中，用户端可以直接基于基站之前重新为所述用户端配置的新的TA，通过所述第五目标资源将目标数据发送给所述基站。
在上述实施例中，户端还可以基于基站重新配置的新的TA，在与基站完成随机接入过程之后，通过基站重新为所述用户端分配的第五目标资源，发送目标数据到所述基站。实现了基于新的TA，将目标数据发送给基站的目的。
在一实施例中，基站不再为用户端预留第三目标资源，可选地，可以由基站决定所述第三目标资源所包括的资源单元的数目，例如，基站确定用户端经常出现TA失步时，基站确定对用户端继续进行资源预留的意义不大，此时可以不再为用户端预留所述资源集合中的所有资源单元，即所述第三目标资源可以包括所述资源集合中的所有资源单元。
如果用户只是偶尔出现失步现象，那么基站仍然可以保留所述资源集合中的部分资源单元，即所述第三目标资源可以只包括第二目标资源，或者所述第三目标资源可以包括所述第二目标资源和所述资源集合中位于所述第二目标资源之后的至少一个资源单元。
如果所述第三目标资源包括所述第二目标资源和所述资源集合中位于所述第二目标资源之后的至少一个资源单元，则用户端可以直接获取协议中预先定义的位于所述第二目标资源之后的资源单元的数目，或者所述用户端还可以接收由所述基站通过预设信令发送的位于所述第二目标资源之后的资源单元的数目。
用户端在确定了所述第二目标资源之后的资源单元的数目之后，可以不再使用所述第三目标资源发送后续数据。基站则可以将第三目标资源分配为其他用户端，从而节省物理网中的资源。
下面再从基站侧介绍本公开实施例提供的数据传输方法。
本公开实施例还提供了另一种数据传输方法，可以用于基站。参照图5所示，图5是根据一示例性实施例示出的另一种数据传输方法流程图，可以包括以下步骤：
在步骤201中，检测是否接收到用户端发送的随机接入信号和目标通知消息中的至少一项；
其中，所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，以及指示所述基站不再为所述用户端预留所述第三目标资源；或所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，所述目标通知消息用于指示所述基站不再为所述用户端预留第三目标资源；所述第三目标资源至少包括第二目标资源，所述第二目标资源是基站预先分配给所述用户端用于进行免授权数据上报的资源集合中的任一资源单元；
在步骤202中，如果检测到所述随机接入信号和所述目标通知消息中的至少一项，则根据所述随机接入信号，重新配置并返回新的传输时间提前量TA到所述用户端；
在步骤203中，根据所述随机接入信号和所述目标通知消息中的至少一项，不再为所述用户端预留所述第三目标资源。
上述实施例中，可以在用户端当前的TA已经失效时，由基站为所述用户端配置新的TA，且让基站不再为所述用户端保留第三目标资源，节省了物联网中的资源。
针对上述步骤201，第一种情况下，基站侧可能会只接收到随机接入信号，该随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，以及指示所述基站不再为所述用户端预留所述第三目标资源。
此时，所述随机接入信号是所述基站预先分配给所述用户端的第一指定随机接入前导码。
相应地，步骤201可以具体为：
在第一目标资源上检测是否接收到用户端通过第一随机接入信令发送的所述第一指定随机接入前导码；所述第一目标资源是与第二目标资源关联的满足指定条件的一个随机接入资源单元。
在基站侧确定第一目标资源的方式与终端侧在步骤101中确定第一 目标资源的方式相同，在此不再赘述。
本步骤中，基站只在第一目标资源上检测是否接收到用户端通过第一随机接入信令，例如msg.1发送的第一指定随机接入前导码即可。
第二种情况下，基站侧会接收到用户端发送的随机接入信号和目标通知消息，所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，所述目标通知消息用于指示所述基站不再为所述用户端预留所述第三目标资源。
此时，所述随机接入信号是所述基站预先分配给所述用户端的第二指定随机接入前导码，该第二指定随机接入前导码只用于指示基站需要重新为所述用户端配置新的TA。所述目标通知消息则可以是预设标识信息，例如基站预先分配给所述用户端的C-RNTI，该目标通知消息用于指示基站不再为所述用户端预留第三目标资源。
相应地，步骤201可以具体为：
在第一目标资源上检测是否接收到用户端通过第一随机接入信令发送的所述第一指定随机接入前导码；
在第四目标资源上检测是否接收到用户端通过第二随机接入信令发送的所述预设标识信息。
此时，基站可以在第一目标资源上检测是否接收到用户端通过第一随机接入信令，例如msg.1发送的第二指定随机接入前导码，同时基站需要在第四目标资源上检测是否接收到用户端通过第二随机接入信令，例如msg.3发送的预设标识信息。
本公开实施例中，第四目标资源则是基站在与用户端进行随机接入过程中分配给所述用户端的可以承载第二随机接入信令的资源。
针对上述步骤202，如果基站在第一目标资源上检测接收到用户端通过第一随机接入信令发送的第一指定随机接入前导码或第二指定随机接入前导码，则基站均可以重新为所述用户端配置新的TA。
针对上述步骤203，如果基站在第一目标资源上检测接收到用户端 通过第一随机接入信令发送的第一指定随机接入前导码，本步骤中，基站还可以根据所述第一指定随机接入前导码，不再为所述用户端预留所述第三目标资源，可选地，所述第三目标资源至少包括了第二目标资源。
如果基站在第四目标资源上检测接收到用户端通过第二随机接入信令发送的预设标识信息，则基站还可以根据所述预设标识信息，同样不再为所述用户端预留所述第三目标资源，可选地，所述第三目标资源至少包括了第二目标资源。
本公开实施例中，基站可以将第三目标资源分配给其他用户端使用，从而在用户端当前的TA已经失效时，不再为所述用户端预留第三目标资源，实现了节省物理网中的资源的目的。
在一实施例中，基站接收到的第二随机接入信令中还包括了所述用户端当前需要上报给所述基站的目标数据。
相应地，参照6所示，图6是根据图5所示的实施例示出的另一种数据传输方法流程图，上述方法还可以包括以下步骤：
在步骤204中，获取所述第二随机接入信令中的所述目标数据。
本步骤中，基站可以在第二随机接入信令中读取目标数据。
上述实施例中，可以在与基站进行随机接入的过程中，获取到用户端通过第二随机接入信令发送的目标数据。
在一实施例中，参照7所示，图7是根据图5所示的实施例示出的另一种数据传输方法流程图，上述方法还可以包括以下步骤：
在步骤205中，在与所述用户端完成随机接入过程之后，为所述用户端重新分配用于进行数据上报的第五目标资源；
本步骤中，基站可以在与所述用户端完成了随机接入过程之后，重新为所述用户端配置第五目标资源，让所述用户端通过第五目标资源来上报目标数据。
在步骤206中，接收所述用户端通过所述第五目标资源发送的目标数据，所述目标数据是所述用户端当前需要上报给所述基站的数据。
本步骤中，如果基站为用户端配置了第五目标资源，则基站可以读取用户端通过第五目标资源上报的目标数据。
上述实施例中，实现了在基站侧获取用户端通过重新分配的第五目标资源上报的目标数据的目的。
在一实施例中，基站可以决定不再为所述用户端预留的所述第三目标资源所包括的资源单元的数目，例如，基站确定用户端经常出现TA失步时，基站确定对用户端继续进行资源预留的意义不大，此时可以不再为用户端预留所述资源集合中的所有资源单元，即所述第三目标资源可以包括所述资源集合中的所有资源单元。
如果用户只是偶尔出现失步现象，那么基站仍然可以保留所述资源集合中的部分资源单元，即所述第三目标资源可以只包括第二目标资源，或者所述第三目标资源可以包括所述第二目标资源和所述资源集合中位于所述第二目标资源之后的至少一个资源单元。
如果基站确定所述第三目标资源包括所述第二目标资源和所述资源集合中位于所述第二目标资源之后的至少一个资源单元，则基站可以直接获取协议中预先定义的位于所述第二目标资源之后的资源单元的数目，或者基站还可以通过RRC层来确定位于所述第二目标资源之后的资源单元的数目，并通过预设信令，例如RRC信令将位于所述第二目标资源之后的资源单元的数目发送给所述用户端。
基站不再为所述用户端预留所述第三资源之后，可以将所述第三资源留给其他用户端使用，从而在所述用户端当前的TA失效时，不再为所述用户端预留第三目标资源，节省了物联网中的资源。
在一实施例中，参照图8所示，图8是根据一示例性实施例示出的另一种数据传输方法流程图，可以包括以下步骤：
在步骤301中，用户端在目标时间单元对当前的传输时间提前量TA进行检测，获得检测结果。
其中，所述目标时间单元是在第一目标资源所对应的第一个时间单 元之前的任一个时间单元，所述第一目标资源是与第二目标资源关联的满足指定条件的一个随机接入资源单元，所述第二目标资源是基站预先分配给所述用户端用于进行免授权数据上报的资源集合中的任一资源单元。
在步骤302中，如果所述检测结果指示当前的TA已经失效，则用户端通过第一目标资源发送包括随机接入信号的第一随机接入信令到所述基站。
所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA，以及指示所述基站不再为所述用户端预留所述第三目标资源。可选地，所述随机接入信号是所述基站预先分配给所述用户端的第一指定随机接入前导码，所述第一随机接入信令是msg.1信令。
在步骤303中，基站在第一目标资源上检测是否接收到所述用户端通过第一随机接入信令发送的第一指定随机接入前导码。
在步骤304中，基站确定在第一目标资源上否接收到所述用户端通过第一随机接入信令发送的第一指定随机接入前导码，则根据所述第一指定随机接入前导码，重新配置并返回新的传输时间提前量TA到所述用户端。
在步骤305中，基站根据所述第一指定随机接入前导码，不再为所述用户端预留所述第三目标资源。
上述实施例中，用户端可以在目标时间单元对当前的TA进行检测，相比现有技术实现了提前对当前的TA进行检测的目的。另外，用户端可以通过随机接入信号指示所述基站需要重新为所述用户端配置新的TA，以及同时用于指示所述基站不再为所述用户端预留所述第三目标资源，实现了节省物联网中资源的目的。
在一实施例中，参照图9所示，图9是根据一示例性实施例示出的另一种数据传输方法流程图，可以包括以下步骤：
在步骤401中，用户端在目标时间单元对当前的传输时间提前量TA进行检测，获得检测结果。
其中，所述目标时间单元是在第一目标资源所对应的第一个时间单元之前的任一个时间单元，所述第一目标资源是与第二目标资源关联的满足指定条件的一个随机接入资源单元，所述第二目标资源是基站预先分配给所述用户端用于进行免授权数据上报的资源集合中的任一资源单元。
在步骤402中，如果所述检测结果指示当前的TA已经失效，则用户端通过第一目标资源发送包括随机接入信号的第一随机接入信令到所述基站。
所述随机接入信号用于指示所述基站需要重新为所述用户端配置新的TA。可选地，所述随机接入信号是所述基站预先分配给所述用户端的第二指定随机接入前导码，所述第一随机接入信令是msg.1信令。
在步骤403中，基站在第一目标资源上检测是否接收到所述用户端通过第一随机接入信令发送的第二指定随机接入前导码。
在步骤404中，基站确定在第一目标资源上接收到所述用户端通过第一随机接入信令发送的第二指定随机接入前导码，则根据所述第二指定随机接入前导码，重新配置并返回新的传输时间提前量TA到所述用户端。
在步骤405中，如果所述检测结果指示当前的TA已经失效，则用户端通过第四目标资源发送包括目标通知消息的第二随机接入信令到所述基站。
第四目标资源是由所述基站在与所述用户端进行随机接入的过程中为所述用户端分配的用于承载所述第二随机接入信令的资源，所述目标通知消息可以采用预设标识信息，例如C-RNTI，第二随机接入信令可以是msg.3。
在步骤406中，基站在第四目标资源上检测是否接收到所述用户端通过第二随机接入信令发送的预设标识信息。
在步骤407中，基站确定在第四目标资源上接收到所述用户端通过第二随机接入信令发送的预设标识信息，则根据所述预设标识信息，不再为所述用户端预留所述第三目标资源。
上述实施例中，用户端可以在目标时间单元对当前的TA进行检测，相比现有技术实现了提前对当前的TA进行检测的目的。另外，用户端可以通过随机接入信号指示所述基站需要重新为所述用户端配置新的TA，以及通过目标通知消息指示所述基站不再为所述用户端预留所述第三目标资源，实现了节省物联网中资源的目的。
