In other words, the uplink resource allocated by the eNodeB to a certain UE by the UL grant is determined. The UE determines which logical channels are placed and how much data is placed for each logical channel based on the configuration given by the RRC signaling and the rules specified by the protocol.

When the PBR of a logical channel is configured to be infinity ("infinity"), the logical channel lower than its priority will be considered only when the resources of the logical channel are satisfied.

一种数据传输方法及电子终端 技术领域
本发明涉及通信领域,尤其涉及一种数据的传输方法及电子终端。
背景技术
在长期演进(Long Term Evolution,LTE)网络中,无线基站eNodeB为每个用户设备(User Equipment,UE)分配一种numerology/传输时间间隔(Transmission Time Interval,TTI)长度的上行授权(Uplink grant,UL grant),UE只能根据逻辑信道的优先级进行资源分配,只有当所有高优先级的逻辑信道的数据都发送完毕且UL grant还未耗尽的情况下,低优先级的逻辑信道才能得到服务。即此时UE最大化高优先级的逻辑信道的数据传输。

具体实施方式
下面将结合本发明实施例中的附图,对本发明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发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
现有的LTE中的逻辑信道优先级处理(LCP)过程为:在LTE中,无线基站eNodeB是基于每个UE分配上行无线资源的,哪些逻辑信道的数据能够放入分配的无线资源中传输是由UE决定的。基于来自eNodeB的上行授权(UL grant)分配的上行无线资源,UE需要决定包含在新的MAC PDU中的每个逻辑信道的数据总量。换句话说,eNodeB通过UL grant分配给某UE的上行资源是确定的。该UE基于RRC信令给定的配置,以及协议规定的规则,来决定放置哪些逻辑信道的数据以及每个逻辑信道放置多少数据。
MAC PDU只有一个,但要复用的逻辑信道却有多个,这就要求为每个逻辑信道分配一个优先级。最高优先级的逻辑信道的数据优先包含在MAC PDU中,接着是次高优先级的逻辑信道的数据,以此类推,直到分配的MAC PDU已满或没有更多的数据要发送。每个逻辑信道的优先级是由RRC信令中配置的priority字段决定的,值越小,优先级越高。这种分配方式可能使得高优先级的逻辑信道始终占据着eNodeB分配给该UE的无线资源,从而导致低优先级的逻辑信道被“饿死”。为了避免这种情况,LTE引入了优先比特率(Prioritised Bit Rate,PBR)的概念,即在给逻辑信道分配资源之前,配置好各个逻辑信道的数据数率,从而为每个逻辑信道提供了最小数据速率保证,避免了低优先级的逻辑信道被“饿死”。PBR是通过RRC信令中配置的prioritisedBitRate字段决定的。MAC层使用类似于令牌桶的算法实现MAC复用。该算法的基本思想是基于令牌桶内是否有令牌以及令牌的多少来确定是否发送某逻辑信道的数据,并控制组装在MAC PDU中的该逻辑信道的数据量。
UE为每个逻辑信道j维护一个变量Bj,该变量指示了令牌桶里当前可用的令牌数,且每个令牌对应1Byte的数据。Bj在逻辑信道建立时初始化为0,且每个TTI增加PBR×TTI。Bj的值不能超过桶的最大容量。
LCP过程如附图1所示。当有新传的数据时,UE会按照以下步骤进行LCP过程:
Step1:对于所有Bj>0的逻辑信道,按照优先级递减顺序组包,每个逻辑信道分配的无线资源只能满足PBR的要求。当某个逻辑信道的PBR配置成无穷大(“infinity”)时,只有当这个逻辑信道的资源得到满足后,才会考虑比它优先级低的逻辑信道。Step2:Bj减去逻辑信道j在步骤1里复用到MAC PDU的所有MAC SDUs(服务数据单元)的大小。Step3:如果前两步执行完还剩有上行资源的话,则不管Bj的大小,把剩余的资源按照逻辑信道优先级分配给各个逻辑信道。只有当所有高优先级的逻辑信道的数据都发送完毕且UL grant还未耗尽的情况下,低优先级的逻辑信道才能得到服务。即此时UE最大化高优先级的逻辑信道的数据传输。这种实现方案中,UE只会收到一种numerology/TTI长度的上行授权(UL grant),且UE考虑所有被配置的逻辑信道,进行上面描述的LCP过程,组成MAC PDU。该技术中没有考虑不同的numerology/TTI类型,因而没有考虑对时延敏感业务和不敏感业务的不同处理。
目前对网络传输时延的要求越来越高,一方面许多现有的应用可以从减少时延获得好处,可以增加用户的感受质量。例如,基于TCP的应用、游戏、VoLTE/VoIP(Voice over LTE/voice over IP)的实时应用和视频电话/会议。另一方面有一些新的应用场景或应用具有更高的时延要求,例如汽车的远程控制/驾驶、增强现实应用(例如智能眼镜)、或要求低时延的特定机器通信以及紧急通信。目前标准的传输时间间隔TTI是固定长度的—1ms,即请求、授权或数据的传输在具有固定长度(1ms)的一个子帧中进行,这是UE和eNodeB之间每个packet交换的时延的来源。
为了减少时延,目前研究方向是提供短TTI长度,每个TTI的长度可以由无线资源控制(Radio Resource Control,RRC)信令配置,TTI长度可以被缩短到2个符号或3个符号级别,如附图2所示。在上行数据传输中,短TTI的授权(short TTI grants)主要被用于服务时延敏感的业务。而标准长度TTI的授权则可用于普通的,对时延不敏感的业务。
一个UE可支持来自单个小区的多种numerology。一个无线承载可以被网络配置来映射到一个或多个numerology/TTI长度。eNodeB控制UE可以将哪些逻辑信道映射到哪个numerology和/或TTI。本发明各实施例关注在UE同时具有时延敏感业务和不敏感业务的情况下,UE如何对不同时延要求的业务进行不同处理,以满足它们各自的时延要求。当UE收到不同的TTI长度和/或numerology的上行授权时,UE可以将不同的逻辑信道映射到不同的numerology/TTI长度,即对不同的numerology/TTI长度进行逻辑信道选择,然后执行逻辑信道优先级处理(Logical Channel Prioritization,LCP)过程,将各个业务的数据通过适合各自時延的逻辑信道传输,以使时延敏感的业务被尽快传输。具体的,逻辑信道的选择或映射可以通过限制时延不敏感的数据包不在short TTI中发送,限制时延敏感的数据包不采用1ms TTI发送来实现,以满足时延要求;或在LCP过程中考虑时延。
本发明各实施例将提供满足上述需求的信令方法。这些方法不仅可以被用于LTE  short TTI特性,也可以被用于5G NR中正在讨论的对不同numerology/业务的支持。
UE在上行時可能同时进行时延敏感业务和时延不敏感业务。传统的上行调度采用1ms TTI,可以服务时延不敏感业务;而short TTI上行调度采用2-3个符号长度的TTI,可以服务时延敏感的业务。因此eNB可以将1ms TTI和short TTI都配置给UE,用于这些业务的传输。传统的1ms TTI和short TTI可能出现在一个子帧或不同子帧中。
系统架构如图3所示。其中LTE或5G的基站与UE通过无线接口通信,A、B和C分别表示三种不同的系统参数配置(numerology)或TTI长度(1ms TTI或short TTI等)。附图3主要显示下行方向的通信,实际部署中可以是双向通信(既包含上行也包含下行)。当UE有上行数据要发送时,UE将发送缓存状态报告(Buffer Status Report,BSR)给eNB,指出它的相应逻辑信道(组)的缓存状态。eNB然后对UE调度1ms TTI的上行资源和/或short TTI的上行资源。当UE收到1ms UL grant或short TTI UL grant时,UE将执行LCP过程来将多个逻辑信道的数据复用到一个MAC PDU中,并使用该UL grant的资源分配来发送这个MAC PDU。
本发明中的方案涉及的网元可以是:终端:UE或5G终端;无线接入网(Radio Access Network,RAN):LTE eNB/HeNB/Relay/Femto/Pico,5G基站;核心网(Core Network,CN):LTE核心网或5G核心网。连接关系如附图4所示。其中终端的物理元器件包括处理器1420、存储器1440、发送器1430、接收器1410、天线等物理元件,如附图5所示。
以下实施例主要针对LTE中的short TTI特性,讨论如何进行逻辑信道选择。
实施例一:eNB在高层信令中通知逻辑信道选择的相关信息给UE,例如通过RRC信令。具体地,可以包括如下的不同方法:
方法1.1:如附图6所示,eNB向UE通知数据无线承载(Data radio bearer,DRB)/逻辑信道LC的时延参数以及可选的门限1。
在调度UE的上行传输时,eNB将发送物理下行控制信道(Physical Downlink Control Channel,PDCCH)和/或采用short TTI的PDCCH(Short TTI Physical Downlink Control Channel,sPDCCH),包含UL grant。其中,PDCCH中包含的UL grant为1ms TTI的UL grant,sPDCCH中包含的UL grant为short TTI的UL grant。
收到UL grant后,UE决定对1ms TTI和short TTI的UL grant选择哪些逻辑信道来进行LCP过程。例如:时延低于配置的门限1的逻辑信道可以使用任何UL grant,即short TTI grant和1ms TTI grant都可以使用。时延高于配置的门限1的逻辑信道只能使用1ms TTI的UL grant。如果eNB没有配置该门限1,则UE可以基于自身实现来设置该门限。
eNB配置的时延参数可以是业务服务质量(Quality of Service,QoS)所要求的时延,或者是到业务QoS所要求的时延的索引/指针。UE根据来自eNB的业务QoS所要求的时延参数,确定时延参数高于预设门限的逻辑通道只能使用来自eNB的第一TTI长度的UL grant;或者确定时延参数低于预设门限的逻辑通道使用来自eNB的第二TTI长度的UL grant。具体的,UE可以根据来自eNB的时延参数和门限值,确定与来自eNB的第一TTI长度的UL grant及第二TTI长度的UL grant分别对应的逻辑信道;或者,UE可以根据来自eNB的时延参数和该UE确定的门限值,确定与来自eNB 的第一TTI长度的UL grant及第二TTI长度的UL grant分别对应的逻辑信道来执行LCP过程,将确定的多个逻辑信道的数据复用到一个媒体接入控制协议数据单元MAC PDU(Media Access Control Protocol Data Unit)中。对LCP过程,UE可以执行旧式LCP(legacy LCP),UE也可以优先传输具有更低时延的逻辑信道的数据。
方法1.2:eNB向UE配置DRB/逻辑信道使用下面的一种配置,UE在选择逻辑信道时遵循eNB的配置:
只使用short TTI的UL grant;或者,可以使用short TTI的UL grant或1ms TTI的UL grant中的任何一个;或者只使用1ms TTI的UL grant。
如附图7所示,在调度UE的上行传输时,eNB将发送PDCCH和/或sPDCCH(采用short TTI的PDCCH),其中携带UL grant。UE根据来自eNB的只使用第一TTI长度的逻辑通道的类型,确定符合该类型的逻辑信道只使用所述第一TTI长度的UL grant;或者根据来自eNB的只使用第二TTI长度的逻辑通道的类型,确定符合该类型的逻辑信道只使用所述第二TTI长度的UL grant。
UE根据来自eNB的可使用第一TTI长度或第二TTI长度的逻辑通道的类型,确定符合该类型的逻辑信道使用所述第一TTI长度和第二TTI长度中的一个的UL grant。在收到PDCCH中携带的UL grant(即1ms TTI的UL grant)时,UE选择可以使用1ms TTI的UL grant的逻辑信道执行LCP过程。
在收到sPDCCH中携带的UL grant(即short TTI的UL grant)时,UE选择可以使用short TTI的UL grant的逻辑信道执行LCP过程。
收到1ms TTI/sPDCCH的UL grant时,UE根据上面的配置,选择可以使用1ms TTI/sPDCCH的UL grant的逻辑信道执行LCP过程。
方法1.3,如附图8所示:eNB配置哪些优先级的逻辑信道可以使用short TTI的UL grant。eNB还可以指出优先级的值或优先级的取值范围。
例如:eNB向UE配置4个逻辑信道,逻辑信道分别具有优先级1~4。且eNB配置优先级为1~2的逻辑信道可以使用short TTI的UL grant,则其它优先级的逻辑信道只能使用1ms TTI的UL grant。
在调度UE的上行传输时,eNB将发送PDCCH和/或sPDCCH(采用short TTI的PDCCH),其中携带UL grant。收到sPDCCH中携带的UL grant(即short TTI的UL grant)时,UE只选择具有对应优先级(例如优先级1~2)的逻辑信道来执行LCP过程。在收到PDCCH中携带的UL grant(即1ms TTI的UL grant)时,UE可以选择优先级1~4的逻辑信道,来执行LCP过程。流程如下图所示。UE根据来自eNB的只使用第一TTI长度的逻辑通道的优先级信息,确定符合该优先级信息的逻辑信道只使用所述第一TTI长度的UL grant;或者根据来自eNB的只使用第二TTI长度的逻辑通道的优先级信息,确定符合该优先级信息的逻辑信道只使用所述第二TTI长度的UL grant。
实施例一中eNB通过高层信令(例如RRC信令)来向UE配置针对不同numerology/TTI长度的UL grant的逻辑信道选择的信息,具有半静态配置的特点。能使得UE可针对不同numerology/TTI长度选择对应的逻辑信道,确定待传输的特定业务,可以更好满足业务的时延要求。
实施例二:逻辑信道的配置信息携带在所述UL grant中。如附图9所示,sPDCCH的UL grant(即short TTI的UL grant)或PDCCH的grant(即1ms TTI的UL grant)指示可以使用该UL grant的逻辑信道/优先级信息。
级信息可以在每个short TTI或1ms TTI的UL grant中被指示;或者,为了节省物理层信令开销,逻辑信道/优先级信息可以在第一个short TTI或1ms TTI的UL grant中被指示,之后如果逻辑信道/优先级信息不改变,则不再出现在UL grant中。对于UL grant中如何指示逻辑信道/优先级信息,可以有下面的方法:
方法A:关于逻辑信道/优先级的信息,比如逻辑信道/优先级的索引或标识,可以被包括在UL grant中。方法B:UL grant中携带的PRB或MCS等可以被映射到对应的逻辑信道/优先级。例如,UE被eNB配置或被预配置PRB或MCS与逻辑信道/优先级的映射关系。在收到sPDCCH或PDCCH中的UL grant时,UE根据其中包含的PRB或MCS、以及映射关系,选择该UL grant对应的逻辑信道进行LCP过程。方法C:ULgrant自身的位置/资源可以被映射到对应的逻辑信道/优先级。例如,UE被eNB配置或被预配置UL grant位置/资源与逻辑信道/优先级的映射关系。在收到sPDCCH或PDCCH中的UL grant时,UE根据其中UL grant的位置/资源以及映射关系,选择该UL grant对应的逻辑信道进行LCP过程。
实施例二区别于实施例一在于,由于sPDCCH的发送比RRC信令的发送更加动态,实施例二中eNB可以根据UE的实时上行buffer状态,灵活和快速地调度UE发送不同逻辑信道的业务。实施例二通过UL grant来指示对应的逻辑信道/优先级信息,更加动态,便于eNB根据调度决策来灵活地调度UE的上行业务数据发送,保证业务的时延要求。其中方法和C节省了物理层sPDCCH/PDCCH的控制信令开销。
实施例三:实施例三主要针对5G NR(New Radio)。NR中eNB和UE都将支持在同一个小区中的多种系统配置参数(numerology)。在一种numerology中可能包含多种TTI长度。本实施例方案是eNB向UE配置每个逻辑信道的numerology参数,例如通过高层RRC信令。关于numerology参数,可以有下面2个方式:
方式3.1:如附图10所示,多个级别的(分层)的numerology参数,分别指示numerology和它下面的TTI类型。第一级别:指示该逻辑信道使用的numerology索引或类型。例如,index1定义为如下表格:
Figure PCTCN2017097155-appb-000001
第二级别:指示该逻辑信道使用的TTI类型,比如short TTI/mini slot grant,常规TTI等。例如,index2定义为如下表格:
Figure PCTCN2017097155-appb-000002
Figure PCTCN2017097155-appb-000003
上面2个级别的索引的定义可以由gNB(5G基站)配置,或者在协议中预定义/预配置。
当UE收到一个UL grant时,UE判断该UL grant对应的numerology/TTI长度类型,然后根据上面的配置,选择对应的逻辑信道进行LCP过程。
方式3.2:如附图11所示,单个级别的numerology参数,例如包含单个索引用于指示numerology和TTI类型。例如可以按照下表指示。
Figure PCTCN2017097155-appb-000004
索引的定义可以由gNB(5G基站)配置,或者在协议中预定义/预配置。
实施例三针对NR中一种numerology可能包含多种TTI长度的特性,提出分层或单层的通知方法,为不同numerology的不同TTI长度的UL grant选择合适的逻辑信道。实施例三区别于现有技术在于考虑NR中的多种numerology以及每种numerology的多种TTI长度,可以更好满足时延敏感业务的时延要求。
本发明各实施例提供的各方案可以对时延敏感业务提供更好的QoS保证,即对不同业务的逻辑信道采取最匹配的TTI长度/numerology的上行授权进行传输,降低了时延,提高了通信质量,满足了用户对高时延应用的需求。
