具体实施方式
以下,对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
(1)本申请实施例中,名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。
(2)本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
(3)“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情 况。字符“/”一般表示前后关联对象是一种“或”的关系。
终端可以利用传统的蜂窝网络接口(Uu接口)进行数据传输,也可以利用直接通信接口(Sidelink接口)进行数据传输。
如图1所示,为蜂窝网络通信方式示意图,即终端和网络侧设备通过Uu接口进行上下行数据/控制信息的传输。在蜂窝网络通信时,网络侧设备会执行QoS flow(业务质量流)到DRB(Data Radio Bearer,数据无线承载)的映射。对于上行,网络侧设备在DRB添加时,会将DRB对应的QoS参数中的Priority Level映射到空口使用的Priority参数,并将Priority参数通知给终端,其中,Priority参数主要用于蜂窝网络通信方式的上行LCP(Logical Channel Prioritization,逻辑信道优先级处理)过程。
如图2所示,为直接通信方式的示意图,直接通信是指相邻的终端可以在近距离范围内通过直接通信链路(Sidelink)进行数据传输。在直接通信方式中,网络侧设备会执行QoS flow到SLRB(Sidelink Radio Bearer,直接通信接口无线承载)的映射,也需要执行LCP过程,且执行LCP过程所需的参数Priority也是根据QoS参数中的Priority Level确定的。
目前,终端只能在一个接口有数据传输需求时,顺利进行数据传输,在两个接口同时有数据传输需求时,会造成数据传输冲突,终端自身无法确定优先在哪个接口上进行数据传输。
本申请实施例中,终端,是一种具有无线通信功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(Mobile Phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality,VR)终端、增强现实(Augmented Reality,AR)终端、工业控制(Industrial Control)中的无线终端、无人驾驶(Self Driving)中的无线终端、远程医疗(Remote Medical)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety)中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端等;还可以是各种形式 的UE,移动台(Mobile Station,MS),终端(Terminal Device)。
网络侧设备可以是基站,是一种为终端提供无线通信功能的设备,包括但不限于:5G中的gNB、无线网络控制器(Radio Network Controller,RNC)、节点B(Node B,NB)、基站控制器(Base Station Controller,BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如,Home Evolved NodeB,或Home Node B,HNB)、基带单元(BaseBand Unit,BBU)、传输点(Transmitting and Receiving Point,TRP)、发射点(Transmitting Point,TP)、移动交换中心等。本申请中的基站还可以是未来可能出现的其他通信系统中为终端提供无线通信功能的设备。
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅仅是本申请一部份实施例,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它实施例,都属于本申请保护的范围。
基于上述场景,本申请实施例提供一种数据传输的方法,用以解决不支持同时在第一接口和第二接口进行数据传输的终端,在第一接口和第二接口同时有数据传输需求时,终端行为不清楚造成数据传输冲突的问题。本申请:不支持同时在第一接口和第二接口进行数据传输的终端,在第一接口和第二接口同时有数据传输需求时,根据第一接口优先级最高的数据的优先级和第二接口优先级最高的数据的优先级进行比较,确定出优先级高的数据,进一步确定优先级高的数据对应的接口,并通过确定的接口发送数据,通过优先级高的数据对应的接口进行数据传输,避免在第一接口和第二接口同时有数据传输需求时产生的数据传输冲突。
在本申请实施例中,当不支持同时在第一接口和第二接口进行数据传输的终端在第一接口和第二接口在同时有数据传输需求时,分别确定每个接口优先级最高的数据。
在确定每个接口优先级最高的数据时,终端针对第一接口将第一接口中 需要传输的数据按照优先级排序,确定出优先级最高的数据;或将第一接口中需要传输的数据的优先级进行比较,确定出优先级最高的数据。
同理,终端针对第二接口将第二接口中需要传输的数据按照优先级排序,确定出优先级最高的数据;或将第一接口中需要传输的数据的优先级进行比较,确定出优先级最高的数据。
上述,分别确定每个接口优先级最高的数据的方式仅是举例说明,任何针对同一接口中需要传输的数据确定优先级最高的数据的方式都适用于本申请。
终端在针对每个接口确定出优先级最高的数据后,将每个接口优先级最高的数据进行优先级比较,确定优先级最高的数据,且确定优先级高的数据对应的接口,并通过确定的接口发送数据。
比如,第一接口确定出的优先级最高的数据为数据A,第二接口确定出优先级最高的数据为数据B,将数据A和数据B的进行优先级比较,若数据A的优先级高于数据B的优先级,则在数据A对应的第一接口发送数据。
其中,在本申请实施例中,当所述第一接口为直接通信接口时,所述第二接口为Uu接口;当所述第一接口为Uu接口时,所述第二接口为直接通信接口。
在本申请实施例中,终端在确定第一接口优先级最高的数据,且确定第二接口优先级最高的数据后,确定第一接口优先级最高的数据,与第二接口优先级最高的数据是否为相同类型的数据。
若为相同类型的数据,则根据设定的规则将每个接口优先级最高的数据的优先级进行比较,即根据设定的规则将第一接口优先级最高的数据和第二接口优先级最高的数据的优先级进行比较,确定优先级高的数据,进一步确定优先级高的数据对应的接口;或
若为不同类型的数据,则按照设定的优先级顺序确定优先级高的数据,即根据设定的优先级顺序将第一接口优先级最高的数据和第二接口优先级最高的数据的优先级进行比较,确定优先级高的数据,进一步确定优先级高的 数据对应的接口。
其中,数据的类型主要分为三类:
1、承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE;
2、来自除公共控制信道知道之外的其他逻辑信道的数据和/或物理层控制信息;
3、用于承载非重要控制信息的MAC CE。
其中,所述用于承载重要控制信息的MAC CE包括下列中的部分或全部:
小区无线网络临时标识媒体接入层控制单元C-RNTI MAC CE;
预配置授权确认媒体接入层控制单元Configured Grant Confirmation MAC CE;
除了用于承载填充缓冲区状态上报媒体接入控制单元Padding BSR MAC CE之外的其他缓冲区状态上报媒体接入控制单元BSR MAC CE;
功率余量上报媒体接入层控制单元PHR MAC CE,包括但不限于:单入口功率余量上报媒体接入层控制单元Single Entry PHR MAC CE或双入口功率余量上报媒体接入层控制单元Multiple Entry PHR MAC CE。
其中,所述用于承载非重要控制信息的MAC CE包括下列中的部分或全部:
建议比特率查询的媒体接入层控制单元Recommended bit rate query MAC CE;
用于承载填充缓冲区状态上报媒体接入控制单元Padding BSR MAC CE;
直接通信链路缓冲区状态上报媒体接入层控制单元Sidelink BSR MAC CE。
在本申请实施例中,当终端确定出第一接口优先级最高的数据与第二接口优先级最高的数据是否为相同类型的数据后,根据确定的结果,采用不同的方式将每个接口优先级最高的数据的优先级进行比较,确定优先级高的数据对应的接口时,通过下列实施例进行详细介绍。
实施例一:第一接口优先级最高的数据与第二接口优先级最高的数据为 不同类型的数据。
当终端确定第一接口优先级最高的数据与第二接口优先级最高的数据为不同类型的数据,所述终端将第一接口优先级最高的数据优先级与第二接口优先级最高的数据的优先级进行比较,确定优先级高的数据对应的接口时,所述终端按照预设的优先级顺序确定优先级高的数据,进一步确定优先级高的数据对应的接口。
其中,所述预设的优先级顺序为:
承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE的优先级高于来自除公共控制信道之外的其他逻辑信道的数据和/或物理层控制信息;
来自除公共控制信道之外的其他逻辑信道的数据和/或物理层控制信息高于用于承载非重要控制信息的MAC CE。
在本申请实施例中,承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE的优先级高于用于承载非重要控制信息的MAC CE。
比如,第一接口优先级最高的数据为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE,第二接口优先级最高的数据为来自除公共控制信道之外的其他逻辑信道的数据和/或物理层控制信息,第一接口优先级最高的数据与第二接口优先级最高的数据为不同类型的数据,则根据上述优先级顺序确定第一接口优先级最高的数据的优先级高于第二接口中优先级数据最高的数据的优先级,因此终端确定通过第一接口发送数据;或
比如,第一接口优先级最高的数据为用于承载非重要控制信息的MAC CE,第二接口优先级最高的数据为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE,第一接口优先级最高的数据与第二接口优先级最高的数据为不同类型的数据,则根据上述优先级顺序确定第二接口优先级最高的数据的优先级高于第一接口优先级最高的数据的优先级,因此终端确定通过第二接口发送数据。
在实施中,当第一接口优先级最高的数据与第二接口优先级最高的数据为不同类型的数据时,根据优先级顺序可以准确的确定出第一接口优先级最 高的数据与第二接口优先级最高的数据之间的优先级高低,因此终端可以根据确定的优先级顺序,确定出优先级高的数据对应的接口,并通过确定的优先级高的数据对应的接口发送数据,避免两个接口同时有数据传输需求时产生的数据传输冲突。
实施例二:第一接口优先级最高的数据与第二接口中优先级数据为相同类型的数据。
当终端确定第一接口优先级最高的数据与第二接口优先级最高的数据为相同类型的数据,所述终端根据设定的规则将第一接口优先级最高的数据与第二接口优先级最高的数据的优先级进行比较,确定优先级最高的数据对应的接口。
其中,所述设定的规则包括下列的部分或全部:
规则1、若分别确定的每个接口优先级最高的数据均为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE,所述终端根据网络配置、协议规定、预配置和随机中的一种确定优先级高的数据对应的接口;
规则2、若分别确定的每个接口优先级最高的数据均为用于承载非重要控制信息的MAC CE,所述终端根据网络配置、协议规定、预配置和随机中的一种确定优先级高的数据对应的接口;
规则3、若分别确定的每个接口优先级最高的数据均为来自除公共控制信道之外的其他逻辑信道的数据和/或物理层控制信息,则所述终端将第一接口优先级最高的逻辑信道的优先级参数和第二接口优先级最高的逻辑信道的优先级参数进行比较,确定优先级高的数据对应的接口。
在本申请实施例中,由于数据类型分为三类,因此当第一接口优先级最高的数据与第二接口优先级最高的数据为相同类型的数据时,不同的类型对应的设定的规则不同,具体分为如下三种情况:
1、第一接口优先级最高的数据与第二接口优先级最高的数据均为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE时对应上述的规则1;
2、第一接口优先级最高的数据与第二接口优先级最高的数据均为用于承载非重要控制信息的MAC CE时对应上述的规则2;
3、第一接口优先级最高的数据与第二接口优先级最高的数据均为来自除公共控制信道知道之外的其他逻辑信道的数据和/或物理层控制信息时对应上述规则3。
针对上述情况进行具体介绍:
情况1、第一接口优先级最高的数据与第二接口优先级最高的数据均为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE。
第一接口优先级最高的数据与第二接口优先级最高的数据均为承载公共控制信道的数据;或
第一接口优先级最高的数据与第二接口优先级最高的数据均为用于承载重要控制信息的MAC CE;或
第一接口优先级最高的数据为承载公共控制信道的数据,第二接口优先级最高的数据为用于承载重要控制信息的MAC CE;或
第一接口优先级最高的数据为用于承载重要控制信息的MAC CE,第二接口优先级最高的数据为承载公共控制信道的数据。
在第一接口优先级最高的数据和第二接口优先级最高的数据均为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE时,所述终端根据网络配置、协议规定、预配置和随机中的一种确定优先级高的数据对应的接口。
其中,由网络配置第一接口和第二接口承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE之间的优先级顺序;

预配置第一接口和第二接口承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE之间的优先级顺序;
随机确定第一接口和第二接口承载公共控制信道的数据和/或用于承载重 要控制信息的MAC CE之间的优先级顺序。
假设,网络配置第一接口承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE的优先级高于第二接口承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE的优先级,当第一接口优先级最高的数据和第二接口优先级最高的数据均为承载公共控制信道的数据时,根据网络配置确定第一接口优先级最高的数据的优先级高于第二接口优先级最高的数据的优先级,因此终端确定通过第一接口发送数据。
在实施中,当第一接口和第二接口同时有承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE的数据传输需求时,在发送数据的冲突时刻,终端根据网络配置、协议约定、预配置、随机确定中的一种确定优先级高的数据,进一步确定优先级高的数据对应的接口,终端在优先级高的数据对应的接口上优先发送数据,避免数据传输冲突。
情况2、第一接口优先级最高的数据与第二接口优先级最高的数据均为用于承载非重要控制信息的MAC CE时。
在第一接口优先级最高的数据和第二接口优先级最高的数据均为用于承载非重要控制信息的MAC CE,所述终端根据网络配置、协议规定、预配置和随机中的一种确定优先级高的数据对应的接口。
其中,由网络配置第一接口和第二接口用于承载非重要控制信息的MAC CE之间的优先级顺序;
协议约定第一接口和第二接口用于承载非重要控制信息的MAC CE之间的优先级顺序;
预配置第一接口和第二接口用于承载非重要控制信息的MAC CE之间的优先级顺序;
随机确定第一接口和第二接口用于承载非重要控制信息的MAC CE之间的优先级顺序。
假设,网络配置第一接口用于承载非重要控制信息的MAC CE的优先级高于第二接口用于承载非重要控制信息的MAC CE的优先级,当第一接口优 先级最高的数据和第二接口优先级最高的数据均为用于承载非重要控制信息的MAC CE时,根据网络配置确定第一接口优先级最高的数据的优先级高于第二接口优先级最高的数据的优先级,因此终端确定通过第一接口发送数据。
在实施中,当第一接口和第二接口同时有用于承载非重要控制信息的MAC CE的数据传输需求时,在发送数据的冲突时刻,终端根据网络配置、协议约定、预配置、随机确定中的一种确定优先级高的数据,进一步确定优先级高的数据对应的接口,终端在优先级高的数据对应的接口上优先发送数据,避免数据传输冲突。
情况3、第一接口优先级最高的数据与第二接口优先级最高的数据均为来自除公共控制信道之外的其他逻辑信道的数据和/或物理层控制信息。
第一接口优先级最高的数据和第二接口优先级最高的数据均为来自除公共控制信道之外的其他逻辑信道的数据;或
第一接口优先级最高的数据和第二接口优先级最高的数据均为物理层控制信息;或
第一接口优先级最高的数据为来自除公共控制信道之外的其他逻辑信道的数据,第二接口优先级最高的数据为物理层控制信息;或
第一接口优先级最高的数据为物理层控制信息,第二接口优先级最高的数据为来自除公共控制信道之外的其他逻辑信道的数据。
在第一接口优先级最高的数据和第二接口优先级最高的数据均为承载公共控制信道的数据和/或用于承载重要控制信息的MAC CE时,所述终端将第一接口优先级最高的逻辑信道的优先级参数和第二接口优先级最高的逻辑信道的优先级参数进行比较,确定优先级高的数据对应的接口。
其中,所述优先级最高的数据为物理层控制信息时,物理层控制信息包括但不限于下列的部分或全部:

若所述物理层控制信息为HARQ反馈,优先级最高的逻辑信道是HARQ反馈对应的TB中包含的优先级最高的逻辑信道;
若所述物理层控制信息为CSI,优先级最高的逻辑信道是终端当前有数据要发送的优先级最高的逻辑信道。
其中,所述优先级最高的数据为来自除公共控制信道知道之外的其他逻辑信道的数据时,优先级最高的逻辑信道是RB(Radio Bearer,无线承载)对应的逻辑信道,RB为DRB/SRB(Signalling Radio Bearer,信令无线承载)。

方式一:将第一接口优先级最高的逻辑信道的优先级参数映射成所述第二接口逻辑信道的优先级参数,并比较所述第一接口优先级最高的逻辑信道的优先级参数和所述第二接口优先级最高的逻辑信道的优先级参数,确定优先级最高的数据对应的接口。
在本申请实施例中,将第一接口优先级最高的逻辑信道的优先级参数映射成所述第二接口逻辑信道的优先级参数时,可以是网络侧设备作为执行主体,网络侧设备将第一接口优先级最高的逻辑信道的优先级参数映射成第二接口逻辑信道的优先级参数,并将映射后得到的第二接口逻辑信道的优先级参数作为第一接口优先级最高的逻辑信道的优先级参数发送给终端,进一步的,终端将作为第一接口优先级最高的逻辑信道的优先级参数的第二接口逻辑信道的优先级参数,和所述第二接口优先级高的逻辑信道的优先级参数进行比较,确定优先级高的数据,进而确定优先级高的数据对应的接口;
还可以是终端作为执行主体,终端根据网络侧设备配置的第一接口逻辑信道的优先级参数和第二接口逻辑信道的优先级参数的第二映射关系,将第一接口优先级最高的逻辑信道的优先级参数进行映射,得到第二接口逻辑信道的优先级参数,将映射后得到的第二接口逻辑信道的优先级参数作为第一接口优先级最高的逻辑信道的优先级参数,进一步的,终端将作为第一接口 优先级最高的逻辑信道的优先级参数的第二接口逻辑信道的优先级参数和所述第二接口优先级高的逻辑信道的优先级参数进行比较,确定优先级高的数据,进而确定优先级高的数据对应的接口。
基于上述内容进行详细介绍。

将第一接口优先级最高的逻辑信道的RLC承载配置信息中的priority参数进行映射,映射后得到第二接口priority参数后,第一接口优先级最高的逻辑信道的RLC承载配置信息中的priority参数用映射后得到的第二接口priority参数表示,因此映射后的第一接口优先级最高的逻辑信道的优先级参 数可以直接与第二接口优先级最高的逻辑信道的RLC承载配置信息中的priority参数进行优先级比较,确定优先级高低。

将第一接口优先级最高的逻辑信道的QoS参数的priority level进行映射,映射后得到第二接口QoS参数的priority level后,第一接口优先级最高的逻辑信道的QoS参数的priority level用映射后得到的第二接口QoS参数的priority level表示,因此映射后的第一接口优先级最高的逻辑信道的优先级参数可以直接与第二接口优先级最高的QoS参数的priority level进行优先级比较,确定优先级高低。
