本公开实施例提供了数据处理方法及装置,避免了高层进行不必要的数据处理,提升了处理效率。其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施例可以相互参见,重复之处不再赘述。
本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分,例如演进的分组系统(Evolved Packet System,EPS)、5G系统(5GS)等。
本公开实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。
本公开实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收 到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本公开实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
3GPP 5G系统引入了XR业务,XR分为如下几类:增强现实(Augmented Reality,AR):将真实世界和虚拟世界无缝集成;虚拟现实(Virtual Reality,VR):利用设备模拟产生一个虚拟世界;混合现实(Mixed Reality,MR):同时包含真实的物理实体与虚拟信息。
XR业务按照数据帧(frame)建模,如图1所示,数据传输时使用分组数据单元集合(Packet Data Unit Set,PDU set)的形式传输。所谓分组数据单元集合就是同一个信息单元(比如一个数据帧)对应的一个或者多个分组数据单元分组数据单元集合。分组数据单元集合内的分组数据单元具有关联性,不同分组数据单元集合之间也可以具有关联性。
如图2所示为5G用户面空口协议栈,对于发送端,一个服务质量流(QoS flow)到达SDAP层后,SDAP层会执行QoS flow到数据无线承载(Data Radio Bearer,DRB)的映射,映射后形成SDAP PDU递交给PDCP层,SDAP PDU即为PDCP服务数据单元(Service Data Unit,SDU)。PDCP层对PDCP SDU进行头压缩、加密等操作后形成PDCP PDU递交给RLC层,然后RLC层再根据MAC层调度信息封装RLC PDU递交给MAC层,MAC层将接收到RLC PDU封装为MAC PDU,然后递交到物理(PHY)层传输。
对于接收端,从MAC层接收到数据,MAC层对收到的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程进行解码,如果解码正确,就会将数据递交到解复用,生成RLC PDU递交到RLC层。RLC层从MAC层接收到RLC PDU后,去掉RLC头重组成RLC SDU(即PDCP PDU)递交PDCP层。PDCP层对PDCP PDU执行解密、完整性校验和重复检测,并递交给高层。
按照上述的数据处理方法,如果数据包成功被底层接收,就会以PDCP PDU的形式递交到PDCP层,PDCP层会对其进行解密、完整性校验和重复检测等处理,然后递交到核心网。但是,对于XR业务,一个分组数据单元集合或者相关联的多个分组数据单元集合内的分组数据单元是有关联关系的,如果有关联关系的分组数据单元中有大量的分组数据单元丢失,那将剩下的部分分组数据单元递交到高层,是完全没必要的,反而会使得高层进行增加大量不必要的处理,降低处理效率。
为此,本公开实施例中提出,针对接收数据的终端或基站,对一个分组数据单元集合或者有关联关系的多个分组数据单元集合内的PDU采用一体化处理,即:在有关联关系的PDU没有大量丢失的情况下,才将其对应的SDU递交到高层,从而避免高层进行不必 要的数据处理,提高处理效率。
图3为本公开实施例提供的数据处理方法的流程示意图。该方法可以是上行的,也可以是下行的,即该方法可以应用于终端或基站。如图3所示,该方法包括:
S301、目标协议层从低层接收PDU。
S302、若相关联的一个或多个PDU中丢失的PDU的个数小于N,则目标协议层对相关联的PDU进行处理得到对应的目标协议层SDU,并将目标协议层SDU递交到目标协议层的高层,其中N为大于或等于1的整数。
本实施例中,执行该数据处理方法的目标协议层可以是PDCP层、RLC层或MAC层。目标协议层为PDCP层时,S301即为PDCP层从低层(RLC层)接收PDCP PDU。目标协议层为RLC层时,S301即为RLC层从低层(MAC层)接收RLC PDU。目标协议层为MAC层时,S301即为MAC层从低层(物理层)接收MAC PDU。
可选的,目标协议层根据接收到的PDU对应的指示信息确定相关联的一个或多个PDU是否丢失。可选的,若目标协议层为PDCP层或RLC层,指示信息携带在PDU的PDU头或者净荷中。可选的,若目标协议层为MAC层,指示信息携带在下行链路控制信息(Downlink Control Information,DCI)中,或者,指示信息携带在PDU中的MAC控制单元(Control Element,CE)中,或者,指示信息携带在PDU中的子PDU的子头中,或者,指示信息携带在PDU中的子PDU的净荷中。
可选的,指示信息包括以下至少一项:PDU对应的分组数据单元集合的标识,例如分组数据单元集合的编号;PDU在PDU对应的分组数据单元集合中的标识,例如分组数据单元集合内的PDU的编号;与PDU对应的分组数据单元集合相关联的其他分组数据单元集合的标识;PDU在PDU对应的分组数据单元集合内的位置,例如比特位置,比特位置可以是头部、中间、尾部的表示方式,或者是具体的比特数值的表示方式;PDU在与PDU对应的分组数据单元集合相关联的多个分组数据单元集合内的位置。
示例的,目标协议层可以根据接收到的PDU对应的分组数据单元集合的标识,以及PDU在PDU对应的分组数据单元集合中的标识,确定与该PDU相关联的PDU,也就是可以确定相关联的PDU是否成功接收,也就是确定是否有丢失的PDU。示例的,目标协议层可以根据接收到的PDU在对应的分组数据单元集合的比特位置,确定与该PDU相关联的PDU是否成功接收,也就是确定是否有丢失的PDU。若相关联的PDU中丢失的PDU的个数小于N,例如N为1或2,对PDU进行处理得到对应的目标协议层SDU,并递交到高层。相应的,若相关联的PDU中丢失的PDU的个数大于等于N,则目标协议层将已接收到的相关联的PDU丢弃。
本公开实施例的数据处理方法中,目标协议层对相关联的PDU采用一体化处理,在相关联的PDU没有大量丢失的情况下,才将其处理为对应的SDU并递交到高层,从而避免高层进行不必要的数据处理,提高处理效率。
需要说明的是,在该方法应用于终端时,终端是否执行上述数据处理方法,也就是是否对相关联的PDU采用一体化处理,可以是由基站配置的或终端自行确定的。终端中执行上述数据处理方法的目标协议层可以是由基站配置的或终端自行确定的。
可选的,终端接收第一配置信息,第一配置信息用于配置终端是否执行该数据处理方法,或者第一配置信息用于基于逻辑信道(Logical Channel,LCH)配置终端是否执行该 数据处理方法,也就是终端是否执行该数据处理方法可以是针对LCH进行配置的,不同的LCH的配置可能不同。
可选的,终端接收第二配置信息,第二配置信息用于配置终端中执行该数据处理方法的目标协议层,目标协议层是PDCP层、RLC层、MAC层中的一项或多项。可选的,若第二配置信息中配置的目标协议层是多个,则终端可以自行从配置的多个目标协议层中确定执行该数据处理方法的目标协议层。第二配置信息和第一配置信息可以携带在同一个配置消息中,也可以分别携带在不同的配置消息中。
以下分别对不同目标协议层的处理过程进行说明。
在一种实施方式中,目标协议层为PDCP层,终端执行以下数据处理过程:
步骤1:接收配置信息。
终端从网络设备接收第一配置信息和第二配置信息,其中,第一配置信息指示终端对相关联的PDU进行一体化处理,第二配置信息指示目标协议层为PDCP层。
步骤2:PDCP层从RLC层接收PDCP PDU。
步骤3:PDCP层根据PDCP PDU的PDU头或者净荷中携带的指示信息确定相关联的PDCP PDU是否成功接收,如果全部成功接收或者丢失的PDCP PDU的个数小于N,则对相关联的PDCP PDU分别执行去PDCP头、解密、完整性校验等操作,并递交到高层。如果相关联的PDCP PDU中大于等于N个PDCP PDU丢失,则直接丢弃接收到的相关联的PDCP PDU。
可选的,PDCP层可以对接收到的PDCP PDU排序,排序窗内如果有大于等于N个PDCP PDU丢失,则直接丢弃接收到的相关联的PDCP PDU。
本实施例的数据处理方法中,PDCP层对从RLC层接收到的相关联的PDCP PDU进行一体化处理,在相关联的PDCP PDU没有大量丢失的情况下,才将其处理为对应的PDCP SDU并递交到高层,从而避免高层进行不必要的数据处理,提高处理效率。
在另一种实施方式中,目标协议层为RLC层,终端执行以下数据处理过程:
步骤1:接收配置信息。
终端从网络设备接收第一配置信息和第二配置信息,其中,第一配置信息指示终端对相关联的PDU进行一体化处理,第二配置信息指示目标协议层为RLC层。
步骤2:RLC层从MAC层接收RLC PDU。
步骤3:RLC层根据RLC PDU的PDU头或者净荷中携带的指示信息确定相关联的RLC PDU是否成功接收,如果全部成功接收或者丢失的RLC PDU的个数小于N,则对相关联的RLC PDU分别执行去RLC头、RLC SDU重组等操作,并递交到PDCP层。如果相关联的RLC PDU中大于等于N个RLC PDU丢失,则直接丢弃接收到的相关联的RLC PDU。
可选的,RLC层可以对接收到的RLC PDU排序,排序窗内如果有大于等于N个RLC PDU丢失,则直接丢弃接收到的相关联的RLC PDU。
