用户终端上传数据的方法及装置、存储设备、用户终端
本申请要求于2018年08月10日提交中国专利局、申请号为201810910105.9、发明名称为“用户终端上传数据的方法及装置、存储设备、用户终端”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。
技术领域
本发明涉及通信技术领域，尤其是涉及一种用户终端上传数据的方法及装置、存储设备、用户终端。
背景技术
随着无线技术的不断发展，3GPP引入新的无线技术(New Radio access technology，NR)，以应对更大数据量的需求以及应对更小传输时延的需求，该技术又称为第五代移动通信技术5G。
在5G中，引入了两种新技术，分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)复制(Duplication)功能和子带(Band Width Part，BWP)，其中，所述子带又称为子带宽。
在具体实施中，引入所述PDCP复制功能可以提高超可靠低延时通信(Ultra Reliable Low Latency Communication，URLLC)业务传输的可靠性。具体地，通过在发送端的PDCP层，将一个PDCP数据包复制成相同的两份并分别采用不同的无线数据链路(Leg)进行传输。更具体而言，下发给两个不同的无线链路控制(Radio Link Control，RLC)实体，进而分别通过不同的发送端逻辑信道(Logical Channel，LCH)进行传输，当成功接收到两份PDCP数据包时，在接收端的PDCP层删除其中一份而只保留一份数据包。也即，将同一份数据包 复制成相同的两份并通过两条不同的路径进行传输，从而提高了数据传输的可靠性。其中，所述PDCP数据包可以包括PDCP协议数据单元(Protocol Data Unit，PDU)以及PDCP业务数据单元(Service Data Unit，SDU)。
然而在现有技术中，采用多少个待使用的发送端逻辑信道发送复制的PDCP数据包，以及采用哪几个待使用的发送端逻辑信道进行数据传输，是网络侧通过信令为UE进行指示的，导致为达到较为灵活的激活/去激活控制，而产生较大的信令开销。

具体实施方式
在现有技术中，支持两条无线数据链路复制(Two-legs duplication)模式的激活/去激活机制。具体而言，针对每一个配置了复制功能的RB，通过一个比特(bit)指示该RB的复制功能激活或去激活。其中复制功能激活可以用于指示PDCP进行复制操作，且两条无线数据链路都进行数据传输；复制功能去激活可以用于指示PDCP不进行复制操作，且只通过主要的无线数据链路(Primary leg)进行数据传输。
然而，对于多连接复制(Multi-connectivity duplication)，配置了复制功能的无线承载(Radio Bearer，RB)可以配置多于两条无线数据链路(leg)，则对于一个RB来说，采用多少个待使用的发送端逻辑信道发送复制的PDCP数据包，以及采用哪几个待使用的发送端逻辑信道进行数据传输，用一个比特进行指示是不清楚的。具体而言，一个比特仅包含有0/1两种状态，也即仅能用于指示两条无线数据链路，无法清楚地指示多连接复制的使用情况。
参照图1，图1是现有技术中一种数据发送方法的工作场景示意图，所述数据发送方法可以用于载波聚合(Carrier Aggregation，CA)场景下的PDCP复制功能架构。
在所述数据发送方法中，发送端PDCP实体110将PDCP数据包分别下发至第一发送端RLC实体121以及第二发送端RLC实体122，并通过第一发送端RLC实体121对应的第一发送端逻辑信道、第二发送端RLC实体122对应的第二发送端逻辑信道下发至发送端介质访问层(Medium Access Control，MAC)130。
由于第一发送端逻辑信道以及第二发送端逻辑信道分别映射到不同的小区上，因此PDCP数据包将分别通过不同的小区，例如第一发送端逻辑信道发送的PDCP数据包通过第一小区141以及第二小区142进行发送，第二发送端逻辑信道发送的PDCP数据包通过第三小区143、第四小区144以及第五小区145进行发送。
进一步地，接收端介质访问层150通过不同的小区，例如第一小区141、第二小区142、第三小区143、第四小区144以及第五小区145分别接收到PDCP数据包，然后上传至对应的第一接收端RLC实体161以及第二接收端RLC实体162，并且通过第一接收端RLC实体161对应的第一接收端逻辑信道、第二接收端RLC实体162对应的第二接收端逻辑信道上传至接收端PDCP实体170。
在具体实施中，每条无线数据链路可以为从发送端PDCP实体110至接收端PDCP实体170的其中一条路径，例如可以是从发送端PDCP实体、发送端RLC实体、发送端介质访问层、小区、接收端介质访问层、接收端RLC实体至接收端PDCP实体。
在现有的CA场景下的PDCP复制功能架构中，可以包括配置、激活、去激活等多个步骤以实现复制功能。
具体而言，在配置步骤中，网络侧(例如基站)可以采用RRC消息为多个无线承载(Radio Bearer，RB)配置PDCP复制功能，为 该RB建立一个额外的复制RLC实体。其中，RRC消息还会指示主RLC实体的小区组ID(Cell group ID)和逻辑信道ID(Logic Channel ID，LCID)。RRC消息也可以为RBs设置复制初始态(例如为激活或者不激活)。
在CA场景下，通常只需要一个MAC实体。通过无线资源控制(Radio Resource Control，RRC)消息，还会配置两个RLC实体分别映射到不同的载波上。
进一步地，配置完成后，需要进一步激活才能够使用复制功能。所述激活/去激活(Activation/Deactivation)的步骤是通过网络侧发送激活/去激活MAC控制元素(Control Element，CE)来实现的，所述MAC CE中包含一个比特表(bitmap)，bitmap中的每一个bit分别对应了一个RB复制配置(RB configured with duplication)，其中某个RB复制配置所对应的bit位指示为1代表激活该RB，所对应的bit位指示为0代表去激活该RB。
其中，所述RB可以包括数据无线承载(Data Radio Bearer，DRB)与信令无线承载(Signaling Radio Bearer，SRB)。
在激活步骤中，某个RB复制配置被激活之后，PDCP层会对数据包进行复制操作，并将相同的两份复制后的PDCP协议数据单元(Protocol Data Unit，PDU)分别发送给这个RB所对应的两个RLC实体，这两个RLC实体将会分别对复制后的PDCP PDU进行发送。
在去激活步骤中，某个RB复制配置被去激活之后，其所对应的逻辑信道(LCH)与载波之间的对应限制就被取消；发送端PDCP层不会对新数据包进行复制操作，并且向主(Primary)RLC实体(即主LCH)发送新数据，而不向副(Secondary)RLC实体(即副LCH)发送新数据；发送端PDCP实体会通知副RLC实体取消(cancel)副LCH中的缓存数据。
参照图2，图2是现有技术中另一种数据发送方法的工作场景示 意图，所述另一种数据发送方法可以用于双连接(Dual Connectivity，DC)场景下的PDCP复制功能架构。
如图2所示，具有多个发送端介质访问层与接收端介质访问层，例如所述发送端介质访问层可以包括第一发送端介质访问层231、第二发送端介质访问层232等；所述接收端介质访问层可以包括第一接收端介质访问层251、第二接收端介质访问层252等。
在具体实施中，每条无线数据链路可以为从发送端PDCP实体110至接收端PDCP实体170的其中一条路径，例如可以是从发送端PDCP实体、发送端RLC实体、发送端介质访问层、小区、接收端介质访问层、接收端RLC实体至接收端PDCP实体。其中，多个发送端介质访问层与发送端RLC实体具有对应关系，多个接收端介质访问层与接收端RLC实体具有对应关系。
在现有的DC场景下的PDCP复制功能架构中，也可以包括配置、激活、去激活等多个步骤以实现复制功能。
具体地，所述配置步骤可以与CA场景相同。
进一步地，配置完成后，需要进一步激活才能够使用复制功能。所述激活/去激活(Activation/Deactivation)的步骤是通过网络侧发送激活/去激活MAC控制元素(Control Element，CE)来实现的，所述MAC CE中包含比特表(bitmap)，bitmap中的每一个bit分别对应了一个RB复制配置(RB configured with duplication)，其中某个RB复制配置所对应的bit位指示为1代表激活该RB，所对应的bit位指示为0代表去激活该RB。
在激活步骤中，某个RB复制配置被激活之后，PDCP层会对数据包进行复制操作，并将相同的两份复制后的PDCP协议数据单元(Protocol Data Unit，PDU)分别发送给这个RB所对应的两个RLC实体，这两个RLC实体将会分别对复制后的PDCP PDU进行发送。
在去激活步骤中，某个RB复制配置被去激活之后，UE将会回 退到分支操作(Split Operation)并会采用原来分支操作的相关配置。
然而在现有技术中，为达到较为灵活的激活/去激活控制，而产生较大的信令开销。
本发明的发明人经过研究发现，在现有技术中，采用多少个待使用的发送端逻辑信道发送复制的PDCP数据包，以及采用哪几个待使用的发送端逻辑信道进行数据传输，是网络侧通过信令为UE进行指示的，存在两个缺点：
1.可配置复制功能的RB以及每个RB中可配置的无线数据链路数目较多，导致激活信令的开销较大；
2.每条无线数据链路的激活状态都有可能会根据传输质量进行调整，导致激活信令的发送过于频繁。
也即要想根据信道传输情况灵活地调整各条leg的激活状态，就会有较大的信令开销；想要节省信令开销，就达不到较为灵活的激活/去激活控制。
在本发明实施例中，通过测试确定已配置PDCP复制功能的每个RB的每条无线数据链路的传输质量参数的测量值；根据每条无线数据链路的传输质量参数的测量值与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路；根据所述待用的无线数据链路的数目，PDCP实体对所述PDCP数据包进行复制，并通过所述待用的无线数据链路发送所述PDCP数据包。采用上述方案，根据每条无线数据链路的传输质量参数与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路，相比于现有技术中需要网络侧发送激活指令通知用户终端待用的无线数据链路，采用本发明实施例中的方案，可以在节省信令开销的基础上使用户终端能够根据无线数据链路的传输质量，自行选择传输质量较好的无线数据链路进行上行数据传输，有助于提高传输质量，以及提高传输资源的利用效率。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参照图3，图3是本发明实施例中一种用户终端上传数据的方法的流程图。所述用户终端上传数据的方法可以包括步骤S31至步骤S33：
步骤S31：通过测试确定已配置PDCP复制功能的每个RB的每条无线数据链路的传输质量参数的测量值；
步骤S32：根据每条无线数据链路的传输质量参数的测量值与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路；
步骤S33：根据所述待用的无线数据链路的数目，PDCP实体对PDCP数据包进行复制，并通过所述待用的无线数据链路发送所述PDCP数据包。
在步骤S31的具体实施中，所述传输质量参数可以用于指示已配置PDCP复制功能的每个RB的每条无线数据链路的传输质量。
具体地，所述传输质量参数可以包括以下一项或多项：单位时间内成功传输的数据量以及信道干扰噪声。
其中，在测试中可以以发送预设数量的数据，并计算单位时间内成功传输的数据量，根据成功传输的数据量与发送的数据量的比较结果，可以确定该无线数据链路的传输质量。
所述单位时间内成功传输的数据量越大，所述传输质量参数可以视为越好。
所述信道干扰噪声通常包括对干扰信号频率的检测，可以包括直接在频域进行测频的技术，例如采用搜索频率窗和毗邻频率窗的测频算法；还可以包括不直接在频域进行测频的技术，例如采用相关卷积器和傅里叶变换算法。
所述信道干扰噪声的测试值越小，所述传输质量参数可以视为越好。
需要指出的是，在本发明实施例中，对于所述单位时间内成功传输的数据量以及信道干扰噪声的测量方式不作具体限制。
在步骤S32的具体实施中，所述单位时间内成功传输的数据量对应的所述预设参数阈值为预设数据量阈值，所述信道干扰噪声对应的所述预设参数阈值为预设噪声阈值。
具体地，根据每条无线数据链路的传输质量参数的测量值与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路的步骤可以包括：如果所述无线数据链路在单位时间内成功传输的数据量大于等于预设数据量阈值，则确定所述无线数据链路为所述待用的无线数据链路。
其中，所述预设数据量阈值可以根据具体情况确定，例如当需要选择传输质量较高的无线数据链路时，可以提高所述预设数据量阈值，而确定的待用的无线数据链路的数量也可能会相应减少，反之当需要选择传输质量较低的无线数据链路时，可以降低所述预设数据量阈值，而确定的待用的无线数据链路的数量也可能会相应增加。
在本发明实施例中，根据所述无线数据链路在单位时间内成功传输的数据量大于等于预设数据量阈值，确定待用的无线数据链路，有助于使用户终端能够根据单位时间内成功传输的数据量，自行选择传输质量较好的无线数据链路进行上行数据传输，有助于提高传输质量，且提高传输资源的利用效率。
具体地，根据每条无线数据链路的传输质量参数的测量值与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路的步骤可以包括：所述无线数据链路的信道干扰噪声小于等于预设噪声阈值，则确定所述无线数据链路为所述待用的无线数据链路。
其中，所述预设噪声阈值可以根据具体情况确定，例如当需要选 择传输质量较高的无线数据链路时，可以降低所述预设噪声阈值，而确定的待用的无线数据链路的数量也可能会相应减少，反之当需要选择传输质量较低的无线数据链路时，可以降低所述预设噪声阈值，而确定的待用的无线数据链路的数量也可能会相应增加。
在本发明实施例中，根据所述无线数据链路的信道干扰噪声小于等于预设噪声阈值，确定待用的无线数据链路，有助于使用户终端能够根据信道干扰噪声，自行选择传输质量较好的无线数据链路进行上行数据传输，有助于提高传输质量，且提高传输资源的利用效率。
在步骤S33的具体实施中，根据所述待用的无线数据链路的数目，PDCP实体对PDCP数据包进行复制，并通过所述待用的无线数据链路发送所述PDCP数据包。
在一种具体实施方式中，PDCP实体从上层接收到1个数据包，在PDCP实体本层进行复制。具体地，可以根据所述待用的无线数据链路的数目为N，PDCP实体对所述PDCP数据包复制N-1次，以得到PDCP数据包的总数为N，进而通过所述待用的无线数据链路发送所述N个PDCP数据包。
在本发明实施例中，根据每条无线数据链路的传输质量参数与预设参数阈值的比较结果，确定所述无线数据链路是否为待用的无线数据链路，相比于现有技术中需要网络侧发送激活指令通知用户终端待用的无线数据链路，采用本发明实施例中的方案，可以在节省信令开销的基础上使用户终端能够根据无线数据链路的传输质量，自行选择传输质量较好的无线数据链路进行上行数据传输，有助于提高传输质量，以及提高传输资源的利用效率。
参照图4，图4是本发明实施例中一种用户终端上传数据的方法的工作场景示意图。所述数据发送方法可以用于DC场景下的PDCP复制功能架构。
在UE上传数据的方法中，UE PDCP实体410将PDCP数据包分 别上传至第一UE RLC实体421、第二UE RLC实体422、……第N UE RLC实体423，并通过第一UE RLC实体421对应的第一UE逻辑信道上传至第一UE介质访问层431，通过第二UE RLC实体422对应的第二UE逻辑信道上传至第二UE介质访问层432，通过第N UE RLC实体423对应的第N UE逻辑信道上传至第N UE介质访问层433。
进一步地，PDCP数据包将分别通过不同的小区，例如第一UE逻辑信道发送的PDCP数据包通过第一小区441进行上传，第二UE逻辑信道发送的PDCP数据包通过第二小区442进行上传，……第N UE逻辑信道发送的PDCP数据包通过第N小区443进行上传。
在本发明实施例中，可以设置为不同的RB设置的预设参数阈值相同或不同。
具体地，可以设置所有配置了复制功能的RB所配置的所有无线数据链路都使用相同的预设参数阈值。例如，UE有三个RB配置了复制功能，并且每个RB所配置的无线数据链路(包括逻辑信道)如图4所示，则第一无线数据链路至第N无线数据链路都使用相同的预设参数阈值。
更具体地，所述相同的预设参数阈值可以为预定义的，例如由协议规定好，不可更改。
所述相同的预设参数阈值还可以为网络侧(例如基站)发送至UE的，后续可以通过重配置对预设参数阈值进行更改。例如可以采用RRC/MAC/PYH消息进行配置。
进一步地，可以设置为不同的RB所对应无线数据链路所使用的预设参数阈值可以相同也可以不同。以N＝12为例进行说明，可以设置无线数据链路1～3共用一个(组)预设参数阈值，也即LCH1～LCH3共用一个(组)门限值；无线数据链路4～7共用一个(组)预设参数阈值，也即LCH4～LCH7共用一个(组)门限值；无线数据链路8～12 共用一个(组)预设参数阈值，也即LCH8～LCH12共用一个(组)预设参数阈值。三个(组)门限值可以相同也可以不同。
在本发明实施例中，为不同的RB设置的预设参数阈值相同或不同，可以根据不同的RB的需求采用较高或者较低的传输质量的无线数据链路，有助于提高选择灵活性，以及进一步提高传输资源的利用效率。
在本发明实施例中，可以设置为不同的无线数据链路设置的预设参数阈值相同或不同。
具体地，每个用于复制的无线数据链路都使用一个(组)独立的预设参数阈值，不同无线数据链路所使用的预设参数阈值可以相同也可以不同。例如：无线数据链路1～12各自使用一个(组)互不相同的独立的预设参数阈值，也即LCH1～LCH12各自使用一个(组)互不相同的独立的预设参数阈值。
在本发明实施例中，为不同的无线数据链路设置的预设参数阈值相同或不同。采用本发明实施例的方案，可以更细致地根据不同的传输需求，根据预设参数阈值，选择具有较高或者较低的传输质量的无线数据链路，即使在同一RB中，也可以实现采用具有不同传输质量的无线数据链路传输数据，有助于进一步提高选择灵活性，以及提高传输资源的利用效率。
需要指出的是，在CA场景下，同样可以设置为不同的RB设置的预设参数阈值相同或不同，还可以设置为不同的无线数据链路设置的预设参数阈值相同或不同，有关的具体实现和有益效果请参照前文及DC场景下的相关描述，此处不再赘述。
