Description
本申请要求在2014年8月8日提交中国专利局、申请号为201410389824.2、发明名称为“一种数据传输方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及无线通信技术领域,尤其涉及一种数据传输方法及装置。
随着越来越多的家庭基站、微小区、中继等众多本地节点的部署,传统的以宏基站为主的网络架构将逐步演变为更多类型基站共存的网络架构,并提供更多层次的网络覆盖。为了改善该多类型基站共存网络架构下的相关性能,一种通过非理想链路实现多eNB间协作/聚合的网络架构被提出。
如图1所示的一种可能的多层网络覆盖环境中,主演进基站(Master eNB,MeNB)与次演进基站(Secondary eNB,SeNB)之间采用非理想的数据/信令接口Xn接口(有线或无线接口),用户设备(User Equipment,UE)可以同时工作在MeNB和SeNB下。当连接到MeNB的UE进入SeNB所对应的小区的覆盖范围时,MeNB可以根据信号强度或负载均衡等考虑,转移UE的部分或全部的数据/信令到SeNB以获得SeNB提供的服务。从而实现UE可以同时使用MeNB和SeNB的资源,及基站间聚合(inter-eNB聚合)。
在该场景下,UE的多个无线承载(Radio Bearer,RB)可以分别通过MeNB控制的主小区组(Master Cell Group,MCG)和SeNB控制的小区组(Secondary Cell Group,SCG)分别承载。其中分离到SeNB的RB可以包括数据无线承载(Data Radio Bearer,DRB)和/或信令无线承载(Signaling Radio Bearer,SRB)。由于SeNB受到MeNB的控制,因此可将SeNB认为是受控eNB,而MeNB是主控eNB。
如2A所示,承载分离的一种架构是UE在MeNB和SeNB有独立的承载,UE在每个eNB上都有独立的分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)实体。
如图2B所示,承载分离的另一种架构是,UE在MeNB上的连接可以有独立的承载。UE在SeNB的连接是将MeNB上的同一个演进型分组系统(Evolved Packet System,EPS)承载的一部分数据分流到SeNB上传输,该EPS承载的PDCP实体仍然在MeNB,而SeNB上是有独立的无线链路控制(Radio Link Control,RLC)实体。
在上述网络结构中,如图3所示,当网络侧需要UE能力的信息用于配置空口连接和调度数据传输等的时候,网络侧可以向UE发起能力获取过程。
UE的传输能力通过多个传输指标体现,对于每个传输指标,UE的该传输指标的不同程
度传输能力通过对应的传输指标参数体现,传输指标参数阈值指示了UE的传输指标的最大传输能力。
目前协议规定对于UE特定的传输指标,为了提高UE吞吐量,MeNB和SeNB所分配的能力比例的和是可以超过100%的,即可以超过UE的该传输指标的最大传输能力。因此,UE数据的传输可能会超过UE的最大处理能力,从而导致UE丢包。由于该数据包的丢失是随机发生的,因此会有可能造成重要的控制信令或数据的丢失,从而影响UE的性能,并可能造成无线链路失败。

下面结合附图和实施例对本申请提供的数据传输方法及装置进行更详细地说明。
在eNB间协作/聚合的架构下,UE的一部分无线承载RB在MeNB管理的MCG(主小区组)上,这部分RB包括控制面承载SRB和用户面承载DRB。而同一UE的另外一部分承载(包括SRB和DRB)在SeNB管理的SCG上。当UE在MCG和SCG上进行数据收发的时候,由于MeNB和SeNB的数据调度各自独立,会出现网络调度的UE的数据收发超过UE处理能力的情况,从而产生UE在数据收发时产生数据丢失的情况,对于重要的数据或信令的传输,该数据的丢失会导致无线链路失败等严重后果。
因此本申请实施例针对在这种承载分离下工作的UE提供了一种数据传输方法及装置,确定重要的数据或信令的传输成功率。
本申请提供一种主演进基站MeNB数据传输方法,如图4所示,包括:
步骤401,MeNB针对UE的一个传输指标,确定UE的该传输指标的最大传输能力;
MeNB可以通过图3所示的过程从UE获取至少一个传输指标阈值参数,根据传输指标阈值参数,确定UE的该传输指标的最大传输能力。
步骤402,MeNB确定对UE的该传输指标的最大传输能力按比例分配时,分配给自身允许使用的第一比例和分配给SeNB允许使用的第二比例;
目前协议规定对于UE特定的传输指标,为了提高UE吞吐量,MeNB和SeNB所分配的能力比例的和是可以超过100%的,即第一比例和第二比例的和可以超过100%,则MeNB使用UE的该传输指标的最大传输能力第一比例进行数据调度传输,及SeNB使用UE在该传输指标的最大传输能力第二比例进行数据调度传输时,UE数据的传输会超过UE的最大处理能力。
MeNB确定第一比例和第二比例可以采用协商过程实现,最终由MeNB确定第一比例和第二比例,且需要将第二比例通知SeNB;
步骤403,MeNB根据第二比例确定自身在需要保证数据传输时使用的第三比例,向SeNB发送信令指示SeNB在需要保证数据传输时使用的第四比例,以使SeNB在需要保证数据传输时,在UE的该传输指标的最大传输能力第四比例范围内进行数据调度传输,其中,第一比例与第四比例的和不大于100%,第二比例与第三比例之和不大于100%;
步骤404,MeNB在需要保证数据传输时,在UE的该传输指标的最大传输能力第三比例范围内进行数据调度传输。
当UE在MCG和SCG上进行数据收发的时候,由于MeNB和SeNB的数据调度各自独立,MeNB和SeNB不会知道对方是否在调度重要信令或数据,因此仅确定第一比例和第二比例,可能会超过UE的最大处理能力。本申请实施例提供的方法,MeNB进一步确定自身在需要保证数据传输时使用的第三比例,且指示SeNB在需要保证数据传输时使用的第四比例。由于第一比例与第四比例的和不大于100%,第二比例与第三比例之和不大于100%。因此,对于MeNB和/或SeNB有重要数据传输的情况,MeNB和SeNB对于UE进行数据调度时,都不会超过UE的最大处理能力,从而保证重要数据传输的成功率。
优选地,在不需要保证数据传输时,MeNB在UE的该传输指标的最大传输能力第一比例范围内进行数据调度传输,SeNB在UE的该传输指标的最大传输能力第二比例范围内进行数据调度传输。
本申请实施例优选针对协议规定可以超过UE传输能力的传输指标,确定MeNB/SeNB需要保证数据传输时使用的第三比例/第四比例。
如可以为协议规定的可以超过UE传输能力的如下任一传输指标:
1)UE在1个传输时间间隔(Transmission Timing Interval,TTI)内可接收的下行传输信道的传输块比特
针对该传输指标,通过传输指标阈值参数-在1个TTI内可接收的下行传输信道的传输块比特的最大值(Maximum number of DL-SCH transport block bits received within a TTI),确定UE的该传输指标的最大传输能力。
2)UE在1个TTI内可传输的上行传输信道的传输块比特
针对该传输指标,通过传输指标阈值参数-在1个TTI内可接收的上行传输信道的传输块比特的最大值(Maximum number of UL-SCH transport block bits transmitted within a TTI),确定UE的该传输指标的最大传输能力。
3)UE的下行传输信道的软比特
针对该传输指标,通过传输指标阈值参数-UE的下行传输信道的软比特的总和(Total number of DL-SCH soft channel bits),确定UE的该传输指标的最大传输能力。
当然还可以是其它协议规定的可以超过UE传输能力的传输指标。
本申请实施例MeNB向SeNB发送携带分配给MeNB自身允许使用的第一比例和/或SeNB在需要保证数据传输时使用的第四比例的信令。SeNB可以直接获得第四比例或者根据第一比例确定第四比例。
针对SeNB,本申请实施例提供一种SeNB的数据传输方法,如图5所示,包括:
步骤501,SeNB针对UE的一个传输指标,确定UE的该传输指标的最大传输能力;
SeNB可以通过图3所示的过程从UE获取至少一个传输指标阈值参数,根据传输指标阈值参数,确定UE在该传输指标的最大传输能力。
步骤502,SeNB根据MeNB发送的信令,确定MeNB指示的SeNB在需要保证数据传输时使用的第四比例,所述第四比例与MeNB对UE的该传输指标的最大传输能力按比例分配时分配给MeNB允许使用的第一比例的和不大于100%;
步骤503,SeNB在需要保证数据传输时,在UE的该传输指标的最大传输能力第四比例范围内进行数据调度传输。
SeNB在需要保证数据传输时使用第四比例。由于第一比例与第四比例的和不大于100%。因此,在SeNB侧有重要数据传输时,MeNB和SeNB的调度不会超过UE的最大处理能力,从而保证SeNB对重要数据的传输成功率。
优选地,还包括:
SeNB确定MeNB对UE的该传输指标的最大传输能力按比例分配时,分配给SeNB允许使用的第二比例;在不需要保证数据传输时,在UE的该传输指标的最大传输能力第二比例范围内进行数据调度传输。
优选地,MeNB发送的信令携带分配给MeNB允许使用的第一比例和/或SeNB在需要保证数据传输时使用的第四比例。SeNB可以直接获得第四比例或者根据第一比例确定第四比例。
优选地,MeNB发送的信令还包括分配给SeNB允许使用的第二比例。当然,第二比例也可以通过其它方式通知SeNB。
下面结合MeNB和SeNB给出本申请实施例数据传输过程,主要包括:
步骤1),对于某一个UE的传输指标(如DL-SCH transport block bits received within a TTI),MeNB从UE获取传输指标阈值参数(Maximum number of DL-SCH transport block bits received within a TTI),确定UE的该传输指标的最大传输能力。
步骤2)MeNB确定对UE的该传输指标的最大传输能力按比例分配时,分配给自身允许使用的第一比例70%和分配给SeNB允许使用的第二比例60%;
步骤3)MeNB根据第二比例60%确定自身在需要保证数据传输时使用的第三比例40%,如图6所示,MeNB向SeNB发送请求改变能力比例(Request change of Capability split)信令,信令包括如下内容:MeNB允许使用的第一比例70%(Allowed 70 at SeNB));和/或SeNB在需要保证数据传输时使用的第四比例(Guaranteed 30%at SeNB);
MeNB也可以顺带发送分配给SeNB允许使用的第二比例60%(Allowed 60 at SeNB)。
优选地,第一比例和第四比例的和为100%,第二比例和第三比例的和为100%,则SeNB保证数据传输时使用的第四比例等于MeNB上剩余的比例((Leftover 30%at MeNB)),MeNB保证数据传输使用的第三比例等于SeNB上剩余的比例(Leftover 40%at SeNB),如图7所示为具体的能力比例分配示意图。
当然,第一比例和第四比例的和可以小于100%,第二比例和第三比例的和也可以小于100%,如MeNB保证数据传输时使用的第三比例可以为30%等,SeNB保证数据传输使用的第四比例可以为25%等。
步骤4),SeNB收到步骤3)中的信息后,返回改变能力比例响应确认收到上述信令,并可以返回相关UE在SCG上的空口配置。
步骤5),MeNB在需要保证数据传输时,在UE的该传输指标的最大传输能力的40%范围内进行数据调度传输,SeNB在需要保证数据传输时,在UE的该传输指标的最大传输能力的30%范围内进行数据调度传输。MeNB在不需要保证数据传输时,在UE的该传输指标的最大传输能力70%范围内进行数据调度传输,SeNB在不需要保证数据传输时,在UE在该传输指标的最大传输能力60%范围内进行数据调度传输。
依照本申请另一优选实施例中,在上述实施例的基础上,可以实现根据SeNB的请求进行比例更新。如图8所示,对于MeNB该数据传输方法还包括:
步骤801,MeNB接收SeNB发送的能力比例更改请求,所述能力比例更改请求包括第一比例更新值、第二比例更新值、第三比例更新值和第四比例更新值中一个或多个;

下面结合MeNB和SeNB给出本申请实施例进行比例更改的数据传输过程,如图10所示,主要包括:
步骤1),SeNB向MeNB发送能力比例更改请求来请求更改相应的能力比例。该请求信息包括:SeNB允许使用的第二比例(图7中的Allowed 60 at SeNB)的更新值;和/或MeNB上允许使用的第一比例(图7中的Allowed 70%at MeNB)的更新值;和/或SeNB保证传输时使用的第四比例(图7中的Guaranteed 30%at SeNB)的更新值;和/或MeNB保证传输时使用的第三比例(图7中的Guaranteed 40%at MeNB)。SeNB可以顺带提供UE在SCG的相关配置信息。
步骤2),MeNB根据步骤1)中收到的能力比例更改请求,如果确定自身不允许接受SeNB的能力比例更改请求时,确定不接受SeNB的能力比例更改请求,向SeNB返回拒绝接受能力比例更改请求的反馈消息(能力比例更改响应);确定自身允许接受SeNB的能力比例更改请求且不需要更改UE的空口配置时,确定接受SeNB的能力比例更改请求,向SeNB返回接受能力比例更改请求的反馈消息(能力比例更改响应);确定自身允许接受SeNB的能力比例更改请求且需要更改UE的空口配置时,向UE发送空口重配置消息对UE进行配置;
步骤3),UE根据步骤2)收到的空口重配置消息进行空口重配置,UE通过RRC连接重配置完成反馈配置是否成功给MeNB。
步骤4),MeNB收到UE配置成功的反馈时,确定接受SeNB的能力比例更改请求,向SeNB返回接受能力比例更改请求的反馈消息(能力比例更改响应)。
步骤5),根据步骤4),如果MeNB反馈不接受SeNB的能力比例更改请求,则MeNB/SeNB依旧根据能力比例更改请求之前协商确定的能力比例,在需要确保数据传输的情况,在UE的该传输指标的最大传输能力第三比例/第四比例范围内进行数据调度传输。如果MeNB反馈接受SeNB的变更能力请求,MeNB和SeNB根据更新后的第三比例/第四比例,在需要确保数据传输的情况,在UE的该传输指标的最大传输能力第三比例更新值/第四比例更新值范围内进行数据调度传输。MeNB和SeNB在调度数据传输的时候,不超过协商允许的最大UE能力范围。
