Description

数据传输方法和装置 技术领域

背景技术
在NR(New Radio，新空口)中，用户设备向基站传输数据，可以采用bundling(打捆传输)方式，也即基站配置给用户设备需要重复传输数据的次数K，以及K个重复传输机会，用户设备通过相同的HARQ(混合自动重传请求，Hybrid Automatic Repeat reQuest)进程，在K个重复传输机会中，重复传输数据K次。
在相关技术中，用户设备在传输新的数据时，若采用bundling方式，需要从基站指示的K个重复传输机会中第一个传输机会开始传输数据，在这种情况下，若在当前的K个传输机会中的非第一个传输机会获取到新的数据要传输时，就需要等到基站指示的下K个传输机会中的第一个传输机会才能传输数据，导致传输新的数据存在较大时延。

图6是根据本公开一个实施例示出的一种传输模块的示意框图。
图7是根据一示例性实施例示出的一种用于传输数据的装置的示意框图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是根据本公开一个实施例示出的一种数据传输方法的示意流程图。本实施例所示的数据传输方法可以应用于用户设备，例如手机、平板电脑、可穿戴设备等。
如图1所示，本实施例所示的数据传输方法可以包括以下步骤。
在步骤S1中，接收基站传输的上行资源分配信息和冗余版本序列，其中，所述上行资源分配信息用于指示重复传输机会的次数、周期、起始时间、HARQ信息和对应的HARQ进程，所述冗余版本序列用于指示所述重复传输机会中的可用传输机会。
在一个实施例中，上行资源分配信息可以是UL grant，而基站既可以通过PDCCH(Physical Downlink Control Channel，物理下行控制信道)向用户设备传输上 行资源分配信息，也可以通过随机接入响应消息携带上行资源分配信息，还可以通过RRC(Radio Resource Control，无线资源控制)消息携带上行资源分配信息。
在一个实施例中，冗余版本序列可以由基站通过RRC消息配置给用户设备，在重复传输机会中传输的数据中，可以包含冗余比特，可以根据不同的生成方式，来生成不同重复传输机会对应的数据中的冗余比特，其中，冗余版本对应于上述生成方式，多个冗余版本可以构成冗余版本序列。根据本实施例，还可以根据冗余版本序列确定所述重复传输机会中的可用传输机会。
例如冗余版本序列为s1-0231，根据该冗余版本序列可以确定重复传输机会中的可用传输机会为第一个重复传输机会。
例如冗余版本序列为s2-0303，根据该冗余版本序列可以确定重复传输机会中的可用传输机会为奇数次重复传输机会，例如重复传输机会的次数为8次，那么可用传输机会为这8次重复传输机会中的第1次重复传输机会、第3次重复传输机会、第5次重复传输机会和第7次重复传输机会。
例如冗余版本序列为s3-0000，根据该冗余版本序列可以确定在重复传输机会的次数为8次的情况下，可用传输机会为这8次重复传输机会中的第8次重复传输机会，在重复传输机会的次数小于8次的情况下，可用传输机会可以是每次重复传输机会。
在一个实施例中，所述重复传输机会的次数为一次打捆传输中重复传输机会的次数。
在步骤S2中，根据所述HARQ信息确定是否需要传输新的数据。
在一个实施例中，HARQ信息可以包括NDI(New data indicator，新数据指示字段)，针对用户设备发起的每个HARQ进程，分别对应一个NDI，用户设备可以存储每个HARQ进程对应的NDI，并在发起新的HARQ进程时，确定新的HARQ进程与过去最近一次发起的HARQ进程对应的NDI是否相同，若不同，则可以确定需要传输新的数据。
当然，HARQ信息除了可以包括NDI，也可以包括其他用于指示是否需要传输新的数据的内容，具体可以根据需要进行设置。
在步骤S3中，若需要传输新的数据，从所述可用传输机会中第一个可用传输机会起，在所述可用传输机会中的每个可用传输机会，尝试获取介质访问控制层根据 所述新的数据生成的协议数据单元。
在一个实施例中，在确定需要传输新的数据的情况下，MAC(Media Access Control，介质访问控制)层可以根据新的数据生成PDU(Protocol Data Unit，协议数据单元)。进而可以从第一个可用传输机会开始，在每个可用传输机会中尝试获取MAC层生成的PDU。
在步骤S4中，若获取到协议数据单元，根据所述次数、周期和起始时间，指示所述HARQ进程从获取到协议数据单元时对应的可用传输机会开始，在每个所述重复传输机会中向所述基站传输所述协议数据单元。
在一个实施例中，若获取到所述协议数据单元，可以确定在获取到协议数据单元时对应的可用传输机会中存在新的数据需要传输，从而可以根据所述次数、周期和起始时间，指示所述HARQ进程从获取到协议数据单元时对应的可用传输机会开始，在每个所述重复传输机会中向所述基站传输所述协议数据单元。
其中，根据所述周期和所述起始时间可以确定在获取到协议数据单元时对应的可用传输机会后，每个所述重复传输机会的起始时间和结束时间。根据所述次数可以确定在获取到协议数据单元时对应的可用传输机会后的重复传输机会的剩余次数。
例如一次打捆传输包含8次重复传输机会，获取到协议数据单元时对应的可用传输机会为8次重复传输机会中的第3次重复传输机会。在这种情况下，在相关技术中，需要在当前打捆传输之后的打捆传输对应的重复传输机会中的第1次重复传输机会来传输协议数据单元，这就导致协议数据单元的传输晚了至少5次重复传输机会对应的时间，而根据本公开的实施例，则可以从当前打捆传输的第3次重复传输机会开始向基站传输协议数据单元。
可见，通过从获取到协议数据单元时对应的可用传输机会开始，在每个所述重复传输机会中向所述基站传输所述协议数据单元，可以保证在需要传输新的数据时，基站能够及时地接收到包含新的数据的协议数据单元，降低传输新的数据的延迟。
可选地，所述上行资源分配信息包含于RRC消息中，和/或包含于物理下行控制信道的消息中，和/或包含于随机接入响应消息中。
在一个实施例中，基站可以通过RRC消息向用户设备传输上行资源分配信息，也可以通过物理下行控制信道向用户设备传输上行资源分配信息，还可以在向用户设备发送随机接入响应时，通过随机接入响应消息携带上行资源分配信息。
需要说明的是，基站可以通过上述三种方式中任意一种方式向用户设备传输上行资源分配信息，也可以通过上述三种方式中任意两种方式向用户设备传输上行资源分配信息，还可以通过上述三种方式中的每种方式向用户设备传输上行资源分配信息。具体可以根据需要进行配置。
图2是根据本公开一个实施例示出的另一种数据传输方法的示意流程图。如图2所示，在图1所示实施例的基础上，所述上行资源分配信息包含于RRC消息中，所述尝试获取介质访问控制层根据所述新的数据生成的协议数据单元包括：
在步骤S31中，从复用与组装实体中尝试获取介质访问控制的协议数据单元。
在一个实施例中，若上行资源分配信息包含于RRC消息中，也即基站通过RRC消息向用户设备传输上行资源分配信息，用户设备中的HARQ实体可以根据上行资源分配信息，在用户设备的进程中确定上行资源分配信息所指示的HARQ进程，并通过复用与组装实体(Multiplexing and assembly entity)把RRC各个逻辑信道的数据(包含需要传输的新的数据)组装成协议数据单元，进而可以从所述可用传输机会中第一个可用传输机会起，在所述可用传输机会中的每个可用传输机会，从复用与组装实体中尝试获取介质访问控制的协议数据单元。
图3是根据本公开一个实施例示出的又一种数据传输方法的示意流程图。如图3所示，在图1所示实施例的基础上，所述HARQ信息包括新数据指示字段，所述根据所述HARQ信息确定是否需要传输新的数据包括：
在步骤S21中，确定所述新数据指示字段与历史上最近的HARQ进程对应的新数据指示字段是否为翻转关系，若为翻转关系，确定需要传输新的数据。
在一个实施例中，由于通过HARQ技术传输数据具体是通过多个HARQ进程对数据重复传输，可以设置当重复传输数据时，HARQ进程对应的新数据指示字段为0，当传输新的数据时，HARQ进程对应的新数据指示字段为1(需要说明的是，新数据指示字段可以包括一个字符，也可以包括多个字符)，那么在重复传输数据时，最后一次重复传输数据的HARQ进程对应的新数据指示字段0，与接下来对于新的数据的重复传输中第一次重复传输数据的HARQ进程对应的新数据指示字段1为翻转关系，据此，可以方便地确定是否需要传输新的数据。
图4是根据本公开一个实施例示出的又一种数据传输方法的示意流程图。如图4所示，在图1所示实施例的基础上，所述根据所述次数、周期和起始时间，指示所 述HARQ进程从获取到协议数据单元时对应的可用传输机会开始，在每个所述重复传输机会中向所述基站传输所述协议数据单元包括：
在步骤S41中，确定获取到协议数据单元时对应的可用传输机会。
在步骤S42中，根据所述获取到协议数据单元时对应的可用传输机会和所述重复传输机会的次数，确定从所述获取到协议数据单元时对应的可用传输机会开始的所述重复传输机会的剩余次数。
在一个实施例中，剩余次数根据获取到协议数据单元时对应的可用传输机会和重复传输机会的次数的不同，可以有所不同。例如可用传输机会为重复传输机会中的第3次重复传输机会，那么在一次打捆传输包含8次重复传输机会的情况下，剩余次数为6次，而在一次打捆传输包含6次重复传输机会的情况下，剩余次数则为4次。
在步骤S43中，根据所述周期和起始时间，指示所述HARQ进程从获取到协议数据单元时对应的可用传输机会开始，在所述剩余次数的所述重复传输机会中向所述基站传输所述协议数据单元。
在一个实施例中，根据所述周期和起始时间，可以确定剩余次数的重复传输机会中每个重复传输机会的起始时间和结束时间，进而可以确定获取到协议数据单元时对应的可用传输机会的起始时间和结束时间，以及获取到协议数据单元时对应的可用传输机会之后的每个重复传输机会的起始时间和结束时间，据此，也就确定了剩余次数的重复传输机会中每个传输机会的起始时间和结束时间，从而可以在剩余次数的重复传输机会中每个传输机会中，从起始时间到结束时间向基站传输所述协议数据单元。
与前述的数据传输方法的实施例相对应，本公开还提供了数据传输装置的实施例。
图5是根据本公开一个实施例示出的一种数据传输装置的示意框图。本实施例所示的数据传输装置可以应用于用户设备，例如手机、平板电脑、可穿戴设备等。
如图5所示，本实施例所示的数据传输装置可以包括以下步骤。
