Description

数据传输方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及数据传输方法、装置及存储介质。
背景技术
在第三代移动伙伴计划(3rd Generation Partnership Project，3GPP)R17中，为了使终端省电，提出了对处于无线资源控制(Radio Resource Control，RRC)非激活(inactive)态的终端能够传输上行小数据(small data)。其中，上行小数据可以在四步随机接入(4-step RACH)或者两步随机接入(2-step RACH)过程中通过上行(uplink，UL)-公共控制信道(Common Control Channel，CCCH)或UL-CCCH1进行传输。
相关技术中，UL-CCCH或者UL-CCCH1所允许传输的最大长度为48/64bits或者56/72bits，并且会有部分用于传输整数个(interger)无线网络临时标识(Radio Network Tempory Identity，RNTI)，简称为I-RNTI。其中I-RNTI的长度为40比特位或24比特位，如果采用已有UL-CCCH或者UL-CCCH1进行小数据的承载，承载的小数据量可能会很小，这样仍需终端进入RRC连接(RRC_connected)态下再进行小数据的传输，所以需对UL-CCCH或UL-CCCH1的格式进行增强。

本公开提供一种数据传输方法，该数据传输方法可以应用于图1所示的无线通信系统中，如图1所示，终端通过诸如基站等网络设备接入到网络中，网络设备与核心网完成数据的回传和前向传递，以进行各种通信服务。
可以理解的是，无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division 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 FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络或系统。本公开中网络可包括无线接入网(Radio Access Network，RAN)以及核心网(Core Network，CN)。网络中包括有网络设备，该网络设备例如可以是无线接入网节点、核心网设备等。其中，无线接入网节点也可以称为基站。网络可以通过网络设备为终端提供网络服务，不同的运营商可以为终端提供不同的网络服务，也可以理解为不同的运营商对应有不同的运营商网络。
终端，也可以称为用户设备(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和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。
终端与网络设备进行通信过程中终端的状态包括有RRC空闲(RRC_idle)态、RRC_inactive态以及RRC连接(RRC_connected)态。终端从RRC_idle态或RRC_inactive态转换为RRC_connected态，需要很多的信令开销，这些信令开销大于小数据的大小，不利于终端省电。故，为了使终端省电，提出了对处于RRC inactive态的终端能够传输上行小数据。
终端在准备接入网络时，需要完成随机接入。相关技术中引入2-step RACH机制和 4-step RACH机制进行随机接入。上行小数据可以在4-step RACH或者2-step RACH过程中的UL-CCCH或UL-CCCH1中传输。
在4-step RACH中，UL-CCCH及UL-CCCH1的长度为the set of 48/64-bits RRC messages。终端在RRC_inactive态中的标识可能为full-I-RNTI，full-I-RNTI在UL-CCCH1中传输占用40bits。终端在RRC_inactive态中的标识也可能为short I-RNTI，short I-RNTI在UL-CCCH中传输占用24bits。如果传输上行小数据需用到MAC-I(占用16bits)加密，则采用CCCH或CCCH1进行小数据传输，只能传输8比特位。如果传输上行小数据不采用MAC-I可传输24bits。在2-step RACH中，消息A(MSGA)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)能够承载56/72bits，按照上述分析，则可确定传输上行小数据最多传输16比特位的数据。
然而，在上行小数据分析中，小数据的数据量可能超过20bits或更多，故，相关技术中通过UL-CCCH/CCCH1传输小数据时，UL-CCCH/CCCH1的已有载荷大小(payload size)是不能够承载的，需对UL-CCCH/CCCH1的payload size加以增强。
本公开实施例提供一种数据传输方法，基于待传输的数据确定增强CCCH。本公开实施例中，增强CCCH可以理解为是增强了payload size的CCCH。进而，通过本公开保证使用足够的比特位进行数据的传输。
可以理解的是，本公开实施例涉及的数据传输方法应用于上行小数据传输场景，在本公开实施例中涉及的数据以及数据传输，在无特殊说明的情况下，数据指上行小数据，数据传输是指处于RRC_inactive态的终端在随机接入过程中使用Msg3或MSGA PUSCH传输小数据。
图2是根据一示例性实施例示出的一种数据传输方法的流程图，如图2所示，数据传输方法用于处于RRC_inactive态的终端中，包括以下步骤。
在步骤S11中，获取配置信息，基于配置信息以及当前待传输的数据，确定增强CCCH。
本公开实施例中，配置信息可以理解为是用于配置增强CCCH的payload size的配置信息。一示例中，配置信息中包括用于配置增强CCCH payload size的参数集。
在步骤S12中，处于RRC_inactive态的终端基于增强CCCH传输小数据。
本公开实施例中，基于配置信息以及当前待传输的小数据，确定增强CCCH，增强控制信道为增强了payload size的CCCH。处于RRC_inactive态的终端基于增强CCCH传输小数据，能够保证使用足够的比特位进行小数据的传输。
本公开实施例中，用于配置增强CCCH的配置信息由网络设备发送，网络设备接收处于RRC_inactive态的终端基于增强CCCH传输的上行小数据。
图3是根据一示例性实施例示出的一种数据传输方法的流程图，如图3所示，数据传输方法用于网络设备中，包括以下步骤。
在步骤S21中，发送配置信息。其中，配置信息中包括用于配置增强CCCH payload size的参数集，增强CCCH是指增强了payload size的CCCH。
在步骤S22中，接收处于RRC_inactive态的终端基于增强CCCH发送的数据。
本公开实施例以下将结合实际应用对上述实施例涉及的数据传输过程进行说明。
一种实施方式中，本公开实施例中用于配置CCCH payload size的配置信息中包括的参数集是以单字节为基准点用于配置增强CCCH的payload size的N个数量级。其中，N为正整数。例如，配置UL-CCCH/CCCH1的payload size时，以一个字节为基准点，譬如8*n，其中n＝0,1,2……，配置信息中可以包括一个或多个n的取值。
本公开实施例中用于配置增强CCCH的payload size的配置信息可以通过系统信息块(System Information Block，SIB)确定。例如，网络设备可以通过SIB信息向终端发送用于配置增强CCCH的配置信息。终端通过SIB信息接收用于配置增强CCCH的配置信息。一示例中，具体在配置UL-CCCH/CCCH1的payload size时，参数集是以单字节为基准点用于配置增强CCCH的payload size的N个数量级，例如N个数量级包括1、2和3。网络设备可以在终端进入RRC_inactive态之前，通过SIB信息下发(1、2和3)这个参数集。终端在确定增强CCCH时，在(1、2和3)这个参数集中选择满足传输需求的数值。
本公开实施例中，增强CCCH可以基于终端选择的参数以及终端当前待传输的数据确定。其中，终端选择的参数可以基于数据的消息类型以及待传输的数据的大小
确定。其中，终端基于配置信息以及当前待传输的数据，确定增强CCCH时，可以基于数据的消息类型以及待传输的数据的大小，在参数集中选择对应的参数，并基于选择的参数确定增强CCCH，使得增强CCCH的payload size满足传输当前消息类型的数据包。
其中，数据的消息类型可以包括RRC建立请求消息(rrcSetupRequest)、RRC连接恢复请求消息(rrcResumeRequest)、RRC重连接请求消息(rrcReestablishmentRequest)，以及RRC系统信息请求消息(rrcSystemInfoRequest)中的一种或多种消息类型。更进一步地，上述的这些信令帧为4-step RACH中的Msg3或是2-step RACH中的MSG A PUSCH。
一示例中，数据的消息类型包括rrcResumeRequest。rrcResumeRequest中包括有整数(interger)个无线网络临时标识(Radio Network Tempory Identity，RNTI)，简称为I-RNTI。I-RNTI可以是长I-RNTI(full-I-RNTI)或短I-RNTI(short I-RNTI)。其中，rrcResumeRequest包括RRCResumeRequest和RRCResumeRequest1两种消息类型。RRCResumeRequest1中包括full I-RNTI，RRCResumeRequest中包括short I-RNTI。Interger 在确定增强CCCH时，基于当前rrcResumeRequest的消息类型，以及待传输的数据包大小，在配置信息的参数集中选择参数，并基于选择的参数确定增强CCCH，使选择的参数确定的增强CCCH的payload size满足传输当前无线资源控制连接恢复请求中包括的I-RNTI以及待传输的数据包。
其中，不同的rrcResumeRequest使用不同的I-RNTI，full-I-RNTI和short I-RNTI在CCCH中传输占用的比特位不同。故在进行增强CCCH确定时，需要确定rrcResumeRequest的消息类型。
本公开实施例中基于系统信息块1(System Information Block，SIB1)中使用的I-RNTI信息确定rrcResumeRequest的消息类型。其中，响应于SIB1使用I-RNTI标识，确定rrcResumeRequest为RRCResumeRequest1。RRCResumeRequest1中包括有full-I-RNTI。响应于SIB1未使用I-RNTI标识，确定rrcResumeRequest为RRCResumeRequest。RRCResumeRequest中包括short I-RNTI。
可以理解的是，本公开实施例中针对其他消息类型的确定过程与可参阅已有相关技术中确定消息类型的过程，在此不再详述。
本公开实施例中，待传输的数据的大小，可以基于实际待传输的数据包大小确定。
本公开实施例中确定了消息类型，以及待传输的数据的大小后，可以选择对应的参数，基于选择的参数确定增强CCCH。本公开实施例中，在确定增强CCCH时，可以确定增强CCCH的基准payload size。基于基准payload size以及选择的参数，确定增强CCCH。
其中，基准payload size可以理解为是对CCCH进行增强之前所使用的CCCH的payload size。对于不同的随机接入机制，CCCH的基准payload size是不同的。例如，针对4-step RACH，UL-CCCH或者UL-CCCH1的基准payload size长度为48/64bits。针对2-step RACH，UL-CCCH或者UL-CCCH1的基准payload size长度为56/72bits。
其中，网络设备为终端配置的随机接入的CCCH参数信息可以4-step RACH的CCCH参数信息，也可以是2-step RACH的CCCH参数信息，还可以是4-step RACH的CCCH参数信息和2-step RACH的CCCH参数信息。
一方面，响应于随机接入的CCCH参数信息包括4-step RACH的CCCH参数信息，可以确定增强CCCH的基准payload size为4-step RACH的UL-CCCH或者UL-CCCH1的payload size长度。
另一方面，响应于随机接入的CCCH参数信息包括2-step RACH的CCCH参数信息，可以确定增强CCCH的基准payload size为2-step RACH的UL-CCCH或者UL-CCCH1的payload size长度。
又一方面，响应于随机接入的CCCH参数信息包括4-step RACH的CCCH参数信息以及2-step RACH的CCCH参数信息，可以确定增强CCCH的基准payload size为2-step RACH的UL-CCCH或者UL-CCCH1的payload size长度。
本公开一示例中，以增强CCCH为增强UL-CCCH或增强UL-CCCH1为例进行说明。在对UL-CCCH或UL-CCCH1的payload size进行增强时，以一个字节为基准点，譬如8*n，其中n＝0,1,2……，其中配置信息通过SIB信息下发给终端。
在终端进入RRC_inactive态之前，基于SIB信息中包括的配置信息确定增强UL-CCCH或增强UL-CCCH1。
例如，一方面，增强CCCH的payload size可以是[48/64]+n*8，其中n＝1,2,3……。其中，payload size为[48/64]+n*8的增强CCCH适用于支持4-step RACH的终端。适用于4-step RACH的增强CCCH可以用于传输MSG3。
另一方面，增强CCCH的payload size可以是[56/72]+n*8，其中n＝1,2,3……。其中，payload size为[56/72]+n*8的增强CCCH适用于2-step RACH的终端。适用于2-step RACH的增强CCCH可以用于传输MSGA PUSCH。
一种实施方式中，响应于终端支持4-step RACH和2-step RACH，且网络侧配置了这两种UL-CCCH参数，终端有小数据需要传输时，选择适用于2-step RACH的增强CCCH(payload size为[56/72]+n*8)。
本公开实施例中，基于上述实施例涉及的确定增强CCCH的方式，可以确定出多种类型的增强CCCH。例如，64+n*8的增强CCCH可以包括4-step UL CCCH1-1、UL CCCH1-2……。48+n*8的增强CCCH可以包括4-step UL-CCCH0-1、UL-CCCH0-2。
72+n*8的增强CCCH可以包括2-step UL CCCH1-1、UL CCCH1-2……。56+n*8的增强CCCH可以包括2-step UL-CCCH0-1、UL-CCCH0-2……。
本公开实施例中确定出多种类型的增强CCCH，进行不同数据包大小的数据包传输时，可以选择匹配的增强CCCH，可以更便于不同数据包大小的传输。
本公开实施例中，基于配置信息以及当前待传输的数据，确定增强CCCH，增强控制信道为增强了payload size的CCCH。基于增强CCCH传输数据，能够保证使用足够的比特位进行数据的传输。
基于相同的构思，本公开实施例还提供一种数据传输装置。
可以理解的是，本公开实施例提供的数据传输装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟 以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
