Description

一种缓冲区状态上报方法、UE、缓冲区状态报告的处理方法及网络侧设备
相关申请的交叉引用
本申请主张在2017年3月24日在中国提交的中国专利申请号No.201710184584.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种缓冲区状态上报方法、UE(User Equipment，用户终端)、缓冲区状态报告的处理方法及网络侧设备。
背景技术
为了支持高可靠低时延的业务传输需求，下一代移动通信网络(例如5G)NR(New Radio，新空口)引入了PDCP(Packet Data Convergence Protocol duplication，分组数据汇聚协议)层数据包duplication(重复)机制。
UE的上行数据传输是由网络侧调度的，网络侧确定上行资源分配情况之后会通过UL grant(上行调度许可)通知UE。网络侧进行上行资源分配的依据是UE要发送的上行数据量，即UE的缓冲区状态。该缓冲区在UE侧，网络侧要想获知该信息，就需要UE向基站进行BSR(Buffer state report，缓冲区状态上报)。然而，目前针对引入了PDCP层数据包duplication的系统，还没有一种进行缓冲区状态上报的方法。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
下一代通信系统(例如5G)的新空口系统主要支持三类业务：eMBB(enhanced Mobile Broadband，增强型宽带通信))、mMTC(massive Machine Type Communications，大量机器类型通信)、URLLC(Ultra-Reliable and Low Latency Communications，高可靠低时延通信)。
对于URLLC，由于其对时延和可靠性都有比较高的要求，目前3GPP(3rd Generation Partnership Project，第三代计划合作伙伴)给出的一种解决方案是引入PDCP层数据包duplication，即通过多个路径传输相同的PDCP 层数据，通过多路传输增益提升传输可靠性，并降低传输时延。参见图1，图1是本公开一些实施例提供的一种PDCP层数据包duplication模型示意图，如图1所示，PDCP层的一个无线承载(对应如图1所示的一个PDCP实体)，在RLC(Radio Link Control，无线链路层控制协议)层通过两个逻辑信道(每个逻辑信道对应图1中的一个RLC实体)分别进行传输，在MAC(Media Access Control，媒体接入控制)层由一个MAC实体进行处理，将来自两个RLC逻辑信道的数据分别映射到不同载波上进行传输。需要说明的是，图1所示的示意图仅仅是以一个配置了数据包复制模式的承载对应两个逻辑信道为例进行示意，但并不以此为限，也就是说，一个配置了数据包复制模式的承载可以对应多个逻辑信道。
基于上述应用环境，本公开提供一种缓冲区状态上报方法，以下将结合具体实施例对本公开的缓冲区状态上报方法进行详细描述。本公开一些实施例中的UE可以是例如手机、计算机、家电设备、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端设备。需要说明的是，在本公开一些实施例中并不限定所述UE的具体类型。本公开一些实施例中的网络侧设备可以是接入网实体，例如基站等。本公开一些实施例中的逻辑信道标识或逻辑信道组标识用于标识逻辑信道或逻辑信道组，例如可以是逻辑信道编号或逻辑信道组编号。
参见图2，图2是本公开一些实施例提供的一种缓冲区状态上报方法的流程示意图，如图2所示，所述方法包括如下步骤：
步骤201、用户终端UE判断是否满足缓冲区状态上报触发条件。
步骤202、若所述UE满足所述缓冲区状态上报触发条件，所述UE向网络侧设备上报缓冲区状态信息，其中，同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态信息分别独立上报。
本公开一些实施例中，所述UE判断是否满足缓冲区状态上报触发条件，若满足所述缓冲区状态上报触发条件，所述UE可以利用最近可用的UL grant(上行调度许可)向所述网络侧设备上报缓冲区状态信息。所述缓冲区状态 上报触发条件可以包括相关技术中LTE(Long Term Evolution，长期演进)系统中的BSR(Buffer State Report，缓存状态上报)触发条件，也可以包括基于下述PDCP层数据包duplication(以下统称数据包复制)模式的新的触发条件。
所述新的触发条件可以包括所述网络侧设备改变了所述UE的至少一个承载的数据包复制模式状态，也就是说，在该种情况下，当网络侧设备针对所述UE的至少一个承载配置了/激活了或者去配置/去激活了数据包复制模式时，所述UE确定满足所述缓冲区状态上报触发条件。所述新的触发条件也可以包括所述UE的至少一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态差值超过预设门限，也就是说，在该种情况下，当所述UE的至少一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态差值超过所述预设门限时，所述UE确定满足所述缓冲区状态上报触发条件。
当然，可以理解的是，所述缓冲区状态上报触发条件可以同时包括相关技术中LTE系统中的BSR触发条件以及上述基于数据包复制模式的新的触发条件，本公开对此不做具体限定。
当所述UE满足所述缓冲区状态上报触发条件时，所述UE向所述网络侧设备上报缓冲区状态信息，在本公开一些实施例中，所述UE将同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态信息分别独立上报。所述UE可以通过一个BSR MAC CE(Media Access Control Control Element，媒体接入控制单元)实现向所述网络侧设备上报缓冲区状态信息，所述一个BSR MAC CE中携带有所述UE对应的所有需要进行缓冲区状态上报的承载的缓冲区状态信息。所述UE也可以通过两个不同的BSR MAC CE向所述网络侧设备上报缓冲区状态信息，其中，一个BSR MAC CE携带所有需要进行缓冲区状态上报且未配置/未激活数据包复制模式的承载的缓冲区状态信息，另一个BSR MAC CE携带所有需要进行缓冲区状态上报的且配置/激活了数据包复制模式的承载的缓冲区状态信息。
所述BSR MAC CE可以分为MAC子头(sub-header)和MAC CE两部分，由于truncated(截短的)BSR和short(短)BSR格式相同，BSR MAC CE 可以分为长BSR和短BSR两种格式。参见图3，图3是本公开一些实施例提供的一种MAC子头的示意图，如图3所示，其中“R”表示预留比特，“E”表示扩展比特，可以用于指示下一个字节是MAC子头还是MAC负荷，LCID为逻辑信道标识(Logical Channel ID)，用于标识对应负荷部分的逻辑信道。参见图4，图4是本公开一些实施例提供的一种短的BSR和截短的BSR的MAC CE格式，如图4所示，其中，LCG ID为逻辑信道组标识(Logical Channel Group ID)，用于标识逻辑信道组，Buffer Size为对应的逻辑信道组中的数据缓存量，图5为长BSR格式的示意图。
由于所述BSR MAC CE的长度不是确定的，在本公开一些实施例中，所述UE向所述网络侧设备上报缓冲区状态信息时可以在所述BSR MAC CE中携带长度域指示信息，用于指示所述BSR MAC CE的长度。所述BSR MAC CE还可以携带逻辑信道标识，所述逻辑信道标识可以携带在所述MAC子头中，也可以携带在所述MAC CE中，本公开一些实施例对此不做具体限定。
所述UE可以仅仅以逻辑信道为单位向所述网络侧设备上报缓冲区状态信息，也可以仅仅以逻辑信道组为单位向所述网络侧设备上报缓冲区状态信息，还可以通过以逻辑信道为单位以及以逻辑信道组为单位两者结合的方式向所述网络侧设备上报缓冲区状态信息。当所述UE以逻辑信道组为单位向所述网络侧设备上报缓冲区状态信息，所述UE会将同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道分别划分到不同的逻辑信道组进行上报，换句话说，同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道分别属于不同的逻辑信道组。
所述UE在向所述网络侧设备上报缓冲区数据量时可以均不区分PDCP层以及RLC层，即所述UE可以向所述网络侧设备上报每个逻辑信道或逻辑信道组的缓冲区数据量，所述每个逻辑信道或逻辑信道组的缓冲区数据量为该逻辑信道或逻辑信道组对应的PDCP层缓冲区数据量及RLC层缓冲区数据量的总和。所述UE在向所述网络侧设备上报缓冲区数据量时也可以区分PDCP层以及RLC层缓冲区数据量，即所述UE也可以向所述网络侧设备分别上报每个逻辑信道或逻辑信道组的PDCP层缓冲区数据量以及RLC层缓冲区数据量。在本公开一些实施例中，所述UE在向所述网络侧设备上报缓冲区数据量时还可以 部分区分PDCP层以及RLC层缓冲区数据量，部分不区分PDCP层以及RLC层缓冲区数据量，例如所述UE可以仅针对配置/激活了数据包复制模式的承载区分PDCP层及RLC层缓冲区数据量，而对于未配置/未激活数据包复制模式的承载不区分PDCP层及RLC层缓冲区数据量。
在本公开一些实施例中，所述UE向所述网络侧设备上报缓冲区状态信息时，对于同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道，每个逻辑信道的RLC层缓冲区数据数据量均取该承载对应的多个逻辑信道的RLC层数据量的最小值。在本公开一些实施例中，所述UE也可以仅向所述网络侧上报其中一个逻辑信道的缓冲区数据量。
可以理解的是，对于未配置/未激活数据包复制模式的承载对应的逻辑信道，所述UE可以使用相关技术中LTE系统中以逻辑信道组为单位的方式上报，也可以使用本公开一些实施例提供的以逻辑信道为单位或以逻辑信道为单位结合以逻辑信道组为单位的组合方式进行上报，本公开对此不做具体限定。
所述网络侧设备接收所述UE上报的缓冲区状态信息，识别配置/激活了数据包复制模式的承载对应的多个不同逻辑信道，并将在同一个配置或激活了数据包复制模式的承载对应的不同逻辑信道上的数据调度到不同的载波上进行传输。所述网络侧设备向所述UE下发UL grant，所述UE接收所述网络侧设备下发的UL grant，根据网络侧设备配置的承载与载波之间的映射关系，进行LCP(Logical Channel Prioritization，逻辑信道优先化处理)过程。
可选地，所述UE判断是否满足缓冲区状态上报触发条件，包括：
当网络侧设备针对所述UE的至少一个承载配置/激活或者去配置/去激活数据包复制模式时，所述UE确定满足所述缓冲区状态上报触发条件；或者
当所述UE的至少一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态差值超过预设门限时，所述UE确定满足所述缓冲区状态上报触发条件。
本公开一些实施例中，所述缓冲区状态上报条件包括基于数据包复制模式下的新的上报触发条件，也就是说，所述缓冲区状态上报触发条件可以包括所述网络侧设备改变了所述UE的至少一个承载的数据包复制模式状态。也就是说，本公开一些实施例中，当所述网络侧设备针对所述UE的至少一个承 载配置了/激活了或者去配置/去激活了数据包复制模式时，所述UE确定满足所述缓冲区状态上报触发条件。所述缓冲区状态上报触发条件也可以包括所述UE的至少一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态差值超过预设门限，也就是说，当所述UE的至少一个配置/激活了数据包复制模式的承载对应的多个逻辑信道的缓冲区状态差值超过预设阈值时，所述UE确定满足所述缓冲区状态上报触发条件。
可选地，所述UE向网络侧设备上报缓冲区状态信息，包括：
所述UE通过第一缓存状态上报媒体接入控制单元BSR MAC CE向所述网络侧设备上报所述UE对应的所有需要进行缓冲区状态上报的承载的缓冲区状态信息；或者
所述UE通过第二BSR MAC CE向所述网络侧设备上报所有需要进行缓冲区状态上报的且未配置/未激活数据包复制模式的承载的缓冲区状态信息，以及所述UE通过第三BSR MAC CE向所述网络侧设备上报所有需要进行缓冲区状态上报的且配置/激活了数据包复制模式的承载的缓冲区状态信息。
本公开一些实施例中，当所述UE满足所述缓冲区状态上报触发条件时，所述UE可以通过向所述网络侧设备发送一条BSR MAC CE上报缓冲区状态信息，也可以向所述网络侧设备发送两条BSR MAC CE上报缓冲区状态信息。具体地，当所述UE向所述网络侧设备发送一条BSR MAC CE时，所述UE通过第一BSR MAC CE向所述网络侧设备上报所述UE对应的所有需要进行缓冲区状态上报的承载的缓冲区状态信息，也就是说，所述第一BSR MAC CE中携带有所述UE对应的所有需要进行缓冲区状态上报的承载的缓冲区状态信息。
当所述UE向所述网络侧设备发送两条BSR MAC CE时，所述UE通过第二BSR MAC CE向所述网络侧设备上报所有需要进行缓冲区状态上报且未配置/未激活数据包复制模式的承载的缓冲区状态信息，以及通过第三BSR MAC CE向所述网络侧设备上报所有需要进行缓冲区状态上报的且配置/激活了数据包复制模式的承载的缓冲区状态信息。
可选地，所述UE通过第一BSR MAC CE向网络侧设备上报所述UE对应的所有承载的缓冲区状态信息，包括：
所述UE以逻辑信道为单位向所述网络侧设备上报缓冲区状态信息；或者
所述UE以逻辑信道组为单位向所述网络侧设备上报缓冲区状态信息；或者
所述UE以逻辑信道为单位向所述网络侧设备上报一部分逻辑信道的缓冲区状态信息，以及以逻辑信道组为单位向所述网络侧设备上报其他逻辑信道的缓冲区状态信息，其中，同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道分别属于不同的逻辑信道组。
本公开一些实施例中，所述UE可以以逻辑信道为单位向所述网络侧设备上报所有需要进行缓冲区状态上报的承载的缓冲区状态信息，所述UE也可以以逻辑信道组为单位向所述网络侧设备上报所有需要进行缓冲区状态上报的承载的缓冲区状态信息，所述UE还可以通过以逻辑信道为单位以及以逻辑信道组为单位两者组合的方式向所述网络侧设备上报所有需要进行缓冲区状态上报的承载的缓冲区状态信息。
当所述UE以逻辑信道为单位向所述网络侧设备上报所有需要进行缓冲区状态上报的承载的缓冲区状态信息时，所述UE向所述网络侧设备发送每个逻辑信道的缓冲区状态信息。参见图6，图6是本公开一些实施例提供的一种BSR MAC CE的内容示意图，如图6所示，当所述UE以逻辑信道为单位向所述网络侧设备上报缓冲区状态信息时，所述BSR MAC CE的一个字节携带有一个逻辑信道的缓冲区状态信息(如图6中所示的Buffer Size)，在本公开的实施例，所述每个字节还携带有每个逻辑信道的标识。需要说明的是，本公开一些实施例提供的所有BSR MAC CE的示意图均是以所述UE最多支持4个逻辑信道或4个逻辑信道组为例，但并不以此为限制，当所述UE支持的逻辑信道或逻辑信道组的个数增加时，所述BSR MAC CE中逻辑信道或逻辑信道组标识占用的比特数相应增加。
所述一个逻辑信道的缓冲区状态信息可以区分PDCP层以及RLC层，也可以不区分PDCP层以及RLC层，还可以部分区分PDCP层以及RLC层，部分不区分PDCP层以及RLC层。即所述一个逻辑信道的缓冲区状态信息可以是该逻辑信道的PDCP层缓冲区数据量以及RLC层缓冲区数据量的总和，也可以分别是该逻辑信道的PDCP层缓冲区数据量以及RLC层缓冲区数据量。所述UE还可以针对配置/激活了数据包复制模式的承载对应的多个逻辑信道区分PDCP 层以及RLC层，而针对未配置/未激活数据包复制模式的承载对应的逻辑信道不区分PDCP层以及RLC层。本实施例中对此不做具体限定。
当所述UE以逻辑信道组为单位向所述网络侧设备上报缓冲区状态信息时，所述UE向所述网络侧设备发送每个逻辑信道组的缓冲区状态信息。参见图7，图7是本公开一些实施例提供的另一种BSR MAC CE的内容示意图，如图7所示，当所述UE以逻辑信道组为单位向所述网络侧设备上报缓冲区状态信息时，所述BSR MAC CE的一个字节携带有一个逻辑信道组的标识以及该逻辑信道组的缓冲区状态信息。
所述UE可以以逻辑信道组为单位对未配置/未激活数据包复制模式的承载以及配置/激活了数据包复制模式的承载分别进行上报，也可以混合进行上报，即未配置/未激活数据包复制模式的承载对应的逻辑信道和配置/激活了数据包复制模式的承载对应的逻辑信道可以是分别属于不同的逻辑信道组，也可以是属于相同的逻辑信道组。需要注意的是，当所述UE以逻辑信道组为单位上报缓冲区状态信息时，无论是哪种方式，均需要保证同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道分别属于不同的逻辑信道组。
所述一个逻辑信道组的缓冲区状态信息可以区分PDCP层以及RLC层，也可以不区分PDCP层以及RLC层，还可以部分区分PDCP层以及RLC层，部分不区分PDCP层以及RLC层。即所述一个逻辑信道组的缓冲区状态信息可以是该逻辑信道组的PDCP层缓冲区数据量以及RLC层缓冲区数据量的总和，也可以分别是该逻辑信道组的PDCP层缓冲区数据量以及RLC层缓冲区数据量。所述UE还可以针对包括配置/激活了数据包复制模式的承载对应的逻辑信道的逻辑信道组区分PDCP层以及RLC层，而针对不包括配置/激活数据包复制模式的承载对应的逻辑信道的逻辑信道组不区分PDCP层以及RLC层。本实施例中对此不做具体限定。
当所述UE通过以逻辑信道为单位以及以逻辑信道组为单位两者组合的方式向所述网络侧设备上报所有需要进行缓冲区状态上报的承载的缓冲区状态信息时，所述UE以逻辑信道为单位向所述网络侧设备上报一部分逻辑信道的缓冲区状态信息，以及以逻辑信道组为单位向所述网络侧设备上报其他逻辑信道的缓冲区状态信息。需要说明的是，本公开一些实施例中，也需要保 证同一个配置/激活了数据包复制模式的承载对应的多个逻辑信道分别属于不同的逻辑信道组。
参见图8，图8是本公开一些实施例提供的另一种BSR MAC CE的内容示意图，如图8所示，所述BSR MAC CE的一些字节(如图8中的字节1～字节N，N为大于等于1的整数)携带有逻辑信道组的标识以及该逻辑信道组的缓冲区状态信息，另一些字节(如图8中的字节N+1～字节N+M，M为大于等于1的整数)携带有逻辑信道的标识以及该逻辑信道的缓冲区状态信息。
本公开一些实施例中，所述UE可以以逻辑信道组为单位向所述网络侧设备上报未配置/未激活数据包复制模式的承载对应的逻辑信道以及配置/激活了数据包复制模式的承载对应的多个逻辑信道中的一个逻辑信道的缓冲区状态信息，且以逻辑信道为单位向所述网络侧设备上报配置/激活了数据包复制模式的承载对应的其他逻辑信道的缓冲区状态信息。本公开一些实施例中，图8中字节1～字节N标识的逻辑信道组中的全部或部分逻辑信道组包括配置/激活了数据包复制模式的承载对应的多个逻辑信道中的一个逻辑信道，字节N+1～字节N+M标识的逻辑信道包括配置/激活了数据包复制模式的承载对应的其他逻辑信道。需要说明的是，图8中字节1～字节N标识的逻辑信道组中每个逻辑信道组包括每一个配置/激活了数据包复制模式的承载对应的多个逻辑信道中的一个逻辑信道，举例而言，假设一个UE支持的承载中有承载A以及承载B配置/激活了数据包复制模式，则图8中某个字节(例如字节1)中标识的逻辑信道组可以包括所述承载A对应的多个逻辑信道中的一个逻辑信道以及所述承载B对应的多个逻辑信道中的一个逻辑信道。
所述UE也可以以逻辑信道组为单位向所述网络侧设备上报未配置/未激活数据包复制模式的承载对应的逻辑信道的缓冲区状态信息，且以逻辑信道为单位向所述网络侧设备上报配置/激活数据包复制模式的承载对应的多个逻辑信道的缓冲区状态信息。本公开一些实施例中，图8中字节1～字节N标识的逻辑信道组只包括未配置/未激活数据包复制模式的承载对应的逻辑信道，字节N+1～字节N+M标识的逻辑信道包括所有配置/激活了数据包复制模式的承载对应的多个逻辑信道。

可选地，所述第一BSR MAC CE、第二BSR MAC CE以及第三BSR MAC CE分别对应的MAC子头中均携带有逻辑信道标识LCID和/或长度域指示信息。
