Description

一种数据处理方法,通信设备和网络设备
本申请要求于2017年01月20日提交中国专利局、申请号为201710051870.5、申请名称为“一种数据处理方法,终端和网络设备”的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种数据处理方法,通信设备和网络设备。
背景技术
在长期演进(英文全称:Long Time Evolution,简称:LTE)协议栈中,用户面协议栈包括包数据汇聚协议(英文全称:Packet Data Convergence Protocol,简称:PDCP)、无线链路控制(英文全称:Radio Link Control,简称:RLC)、媒体访问控制层(英文全称:Media Access Control,简称:MAC)、物理层(英文全称:Physical Layer,简称:PHY)四层。在发送端,每个数据包经过PDCP层完成网络协议(英文全称:Internet Protocol,简称:IP)头压缩和加密处理,并添加PDCP层数据头;经过RLC层完成分段或级联处理,以适配不同的单次传输数据量,并添加RLC数据头;在MAC层,将汇聚不同逻辑信道的数据(每个逻辑信道对应一组PDCP和RLC实体,逻辑信道的数据也称为RLC包数据单元(英文全称:Packet Data Unit,简称:PDU)或MAC服务数据单元(英文全称:Service Data Unit,简称:SDU),并添加可能需要传输的MAC层控制元素(英文全称:Media Access Control Control Element,简称:MAC CE),组成最终的MAC PDU。MAC层将MAC PDU发送给PHY层,由PHY层完成数据发送。在接收端,按照从低层到高层的顺序依次递交数据包完成接收处理。
目前随着通信技术的发展,为了减少数据处理的时延问题,技术人员设计了一种简单的MAC PDU结构,称为透明MAC。在透明MAC PDU中,只包含一个MAC SDU,即只包含一个逻辑信道的数据,同时没有MAC子头。目前这种结构只用于下行寻呼信道(英文全称:Paging Channel,简称:PCH)和广播信道(英文全称:Broadcast Channel,简称:BCH)。其中PCH通过寻呼固定标识(英文全称:Paging Radio Network Temporary Identifier,简称:P-RNTI)接收,BCH通过物理广播信道(英文全称:Physical Broadcast Channel,简称:PBCH)接收,用户设备(英文全称:User Equipment,简称:UE)侧PHY层完成数据解调后通过相应的PCH或BCH向MAC层递交数据,此时MAC层可以不做任何处理,直接将SDU向上递交到RLC层。
对于现在的通信领域来说,需要减少数据处理的时延的情况越来越多,而目前透明MAC只用于下行PCH和BCH,即该透明MAC的应用范围较窄,无法满足通信发展的要求。

具体实施方式
本申请实施例提供了一种数据处理方法,终端和网络设备,用于将透明MAC结构用于通信传输中的上下行数据传输过程中,扩大该透明结构的应用范围以使得满足通信发展的要求。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在LTE协议栈中,用户面协议栈包括PDCP、RLC、MAC、PHY四层。在发送端,每个数据包经过PDCP层完成IP头压缩和加密处理,并添加PDCP层数据头;经过RLC层完成分段或级联处理,以适配不同的单次传输数据量,并添加RLC数据头;在MAC层,将汇聚不同逻辑信道的数据(每个逻辑信道对应一组PDCP和RLC实体,逻辑信道的数据也称为RLC PDU 或MAC SDU,并添加可能需要传输的MAC CE,组成最终的MAC PDU。MAC层将MAC PDU发送给PHY层,由PHY层完成数据发送。在接收端,按照从低层到高层的顺序依次递交数据包完成接收处理。目前随着通信技术的发展,为了减少数据处理的时延问题,技术人员设计了一种简单的MAC PDU结构,称为透明MAC。在透明MAC PDU中,只包含一个MAC SDU,即只包含一个逻辑信道的数据。目前这种结构只用于PCH和BCH。其中PCH通过P-RNTI接收,BCH通过PBCH接收,UE侧PHY层完成数据解调后通过相应的PCH或BCH向MAC层递交数据,此时MAC层可以不做任何处理,直接将SDU向上递交到RLC层。对于现在的通信领域来说,需要减少数据处理的时延的情况越来越多,而目前透明MAC只用于下行PCH和BCH,即该透明MAC的应用范围较窄,无法满足通信发展的要求。
为了解决这一问题,本申请实施例提供如下技术方案:终端获取配置信息,该配置信息用于指示该特定逻辑信道采用透明媒体访问控制层MAC模式,且该特定逻辑信道由该网络设备确定;然后终端根据该配置信息处理媒体访问控制层包数据单元MAC PDU。
本申请实施例提供的技术方案可用于蜂窝通信系统,即可以用于如图1所示的LTE蜂窝通信系统,也可以用于如图2所示的5G或NR通信系统。在图1所示的LTE蜂窝通信系统中,每个eNB下存在多个小区,在每个小区中eNB和UE都可以使用本申请实施例中提供的MAC PDU结构。在图2所示的5G或NR通信系统中,在一个新空口基站(英文全称:New Radio NodeB,简称:NR-NB)下,可能存在一个或多个发射接收端点(英文全称:Transmission Reception Point,简称:TRP),每一个TRP都可以使用本申请实施例中提供的MAC PDU结构。
在本申请实施例中,该终端与该网络设备组成一个通信系统,即当该终端作为数据发送设备时,该网络设备作为该终端的数据接收设备;当该终端作为数据接收设备时,该网络设备作为该终端的数据发送设备。而本申请实施例中,该网络设备作为数据发送设备时构造MAC PDU的方式与该终端相同,而该网络设备作为数据接收设备时解包该MAC PDU的方式与该终端也相同,因此,本申请实施例中以终端为例进行说明,网络设备不再进行赘述。同时网络设备包括但不限于基站、TRP、控制单元CU(Central Unit)、数据单元DU(Data Unit)。
本申请实施例中由于该终端作为数据接收设备和该终端作为数据发送设备对于该MAC PDU的处理方式不同,因此下面分别进行描述:
一、该终端作为数据接收设备时,该终端根据该配置信息解包该MAC PDU。
具体情况如图3所示,本申请实施例中的数据处理方法的一个实施例,包括:
301、终端获取配置信息。
终端获取配置信息,该配置信息用于指示特定逻辑信道采用透明MAC模式,同时该特定逻辑信道由网络设备确定。
本实施例中,该特定逻辑信道由该终端所处的通信系统中的网络设备确定,同时该网络设备确定的该特定逻辑信道的数目可以为一个也可以为多个,具体数目此处不做限定。同时该终端获取该特定逻辑信道的配置信息的方式可以是终端通过协议规定;也可以是由该网络设备确定好该特定逻辑信道之后将该配置信息发送给该终端,具体的方式此处不做 限定。
本实施例中,该特定逻辑信道的配置信息可以包括如下几种可能:
当该特定逻辑信道为单逻辑信道,即该特定逻辑信道的数目为1时,该配置信息具有如下几种情况:
一种可能实现方式中,该配置信息为在该MAC PDU对应的下行控制信息DCI中包含的该特定逻辑信道的逻辑信道信息;
另一种可能实现方式中,该配置信息为该特定逻辑信道指定的特定无线网络临时标识RNTI;
另一种可能实现方式中,该配置信息为在该MAC PDU对应的半静态调度配置信息中的该特定逻辑信道的逻辑信道信息。
当该特定逻辑信道为多逻辑信道,即该特定逻辑信道的数目为大于1的整数时,该配置信息具有如下几种情况:
一种可能实现方式中,该配置信息为该MAC PDU对应的下行控制信息DCI中包含的该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息;
另一种可能实现方式中,该配置信息为该MAC PDU对应的半静态调度配置信息中包含的该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息。
基于上述实现方式中,该特定逻辑信道的逻辑信道信息为该特定逻辑信道的逻辑信道标识ID或该特定逻辑信道的逻辑信道索引,该逻辑信道索引由该网络设备分配,且与逻辑信道标识ID一一对应,采用索引可以用更少的比特数据量表示逻辑信道标识ID;该半静态调度配置信息为无线资源控制RRC配置信息、激活信息或释放信息中的至少一个;该特定逻辑信道的数据量信息为该特定逻辑信道的传输数据的具体字节数或该特定逻辑信道的传输数据的具体字节数占用该MAC PDU总数据量的百分比或该MAC PDU的数据量除以该特定逻辑信道的数目得到的默认值。
本实施例中,该特定逻辑信道的数据量信息为该MAC PDU的数据量除以该特定逻辑信道的数目得到的默认值时,若碰到无法整除的情况,可以事先规定多余的字节的分配方法,比如若该MAC PDU的数据量为23字节,而该网络设备确定的特定逻辑信道有4个,该四个特定逻辑信道分别为逻辑信道1,逻辑信道2,逻辑信道4和逻辑信道5。按照平均整除的方法,每个特定逻辑信道可以分配5个字节,剩余的3个字节可以全部分配给4个特定逻辑信道中的某一个,比如逻辑信道4;也可以按照逻辑信道ID号由小到大的顺序重新分配,这样,最终分配的字节结果如下:逻辑信道1分配6个字节,逻辑信道2分配6个字节,逻辑信道4分配6个字节,逻辑信道5分配5个字节。此处如何分配该MAC PDU的数据量,方法有多种,此处不做限定。
基于上述实现方式,当该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息包含于该DCI中时,该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息可以是隐式的在该DCI中显示也可以是显式的在该DCI中显示。比如假设该特定逻辑信道的逻辑信道信息为逻辑信道ID,且该逻辑信道ID包括5个bit,数据量信息用具体的字节数表示。若该特定逻辑信道的逻辑信道信息是显式的在该DCI中显示,则该DCI中包含该逻 辑信道ID的全部5个bit和该数据量信息的全部5个字节。若该特定逻辑信道的逻辑信道信息是隐式的在该DCI中显示,则可以将该特定逻辑信道用索引号进行表示,在该DCI中可以仅用2个bit用来表示该索引号,比如可以设定该索引号的范围为0至3,其中,索引号0用于指示逻辑信道1,索引号1用于指示逻辑信道2,索引号2用于指示逻辑信道4,索引号3用于指示逻辑信道5。而当数据量信息为该特定逻辑信道的传输数据的具体字节数占用该MAC PDU总数据量的百分比或该MAC PDU的数据量除以该特定逻辑信道的数目得到的默认值时,该数据量信息可以用相应的字节表示该百分比或该默认值,具体的方式此处不做限定。302、网络设备向终端发送MAC PDU。
该网络设备在为特定逻辑信道构造透明MAC结构的下行的MAC PDU,并将该MAC PDU发送给该终端。本实施例中,根据该配置信息的具体形式不同,步骤302与步骤301之间的顺序不同,此处并不做限定。比如若该配置信息为该MAC PDU对应的半静态调度配置信息中包含的该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息,则该网络设备可以先向该终端发送该配置信息,然后在预设时间段内一直采用该配置信息。即步骤301在步骤302之前。若该配置信息为该MAC PDU对应的半静态调度配置信息中包含的该特定逻辑信道的逻辑信道信息和该特定逻辑信道的数据量信息,则该网络设备可以先向该终端发送该配置信息,然后在预设时间段内一直采用该配置信息为该MAC PDU对应的下行控制信息DCI中包含的该特定逻辑信道的逻辑信道信息或为该特定逻辑信道指定的特定无线网络临时标识RNTI时,该步骤301在该步骤302之后。
303、终端根据特定逻辑信道的配置信息解包该MAC PDU。
该终端在接收到该网络设备发送的MAC PDU之后,终端根据该配置信息解包该MAC PDU。即按照配置信息中MAC SDU的逻辑信道ID和/或数据量,在MAC层直接将相应的MAC SDU提取出来递交到RLC层处理,无需处理MAC子头。本实施例中,若该配置信息为在该MAC PDU对应的下行控制信息DCI中包含的该特定逻辑信道的逻辑信道信息,则该终端可以通过小区无线网络临时标识(英文全称:Cell Radio Network Temporary Identifier,简称:C-RNTI)检测PDCCH,获得该DCI信息后,就可以确定该特定逻辑信道以及该MAC PDU为一个透明MAC PDU。
若该配置信息为该特定逻辑信道指定的特定无线网络临时标识RNTI,则该终端在进行PDCCH检测时,会使用包含该RNTI进行PDCCH检测,从而确定该MAC PDU的DCI信息,然后确定该特定逻辑信道以及该MAC PDU为一个透明MAC PDU。
若该配置信息为在该MAC PDU对应的半静态调度配置信息中的该特定逻辑信道的逻辑信道信息,则该终端通过识别该半静态调度配置信息中的特定逻辑信道的逻辑信道信息,从而确定该特定逻辑信道和该MAC PDU为一个透明MAC PDU。
以上为该特定逻辑信道的数目为1时,即为单特定逻辑信道时,该终端只需要确定该特定逻辑信道即可,若该特定逻辑信道的数目大于1时,该终端还需要根据该配置信息确定该各特定逻辑信道包含的数据量信息,这样才可以准确的解包该MAC PDU。具体过程与确定该特定逻辑信道相同,此处不再赘述。
本实施例中,该终端根据该配置信息确定了该特定逻辑信道以及该MAC PDU为透明MAC  PDU之后,该终端可以收到在该PHY层递交的MAC PDU之后,直接将其递交至RLC层,由RLC层负责解包,MAC层将不进行额外的处理任务,因此降低了处理时延。同时保证了下行数据传输不再仅仅限制于下行寻呼信道,其他的信道也可以使用该透明MAC PDU,从而保证该通信系统的传输。
二、该终端作为数据发送设备,该终端根据该配置信息构造该MAC PDU。
具体情况如图4所示,本申请实施例中的数据处理方法的另一个实施例包括:
步骤401与实施例3中的步骤301相同,此处不再赘述。
402、终端根据该配置信息构造MAC PDU。
该终端在获取到该配置信息之后,从该配置信息确定该特定逻辑信息以及该特定逻辑信道的SDU数据量,然后根据该特定逻辑信道的SDU数据量在该MAC PDU结构中组装该特定逻辑信道的待传输数据构成该MAC PDU。
在本实施例中,该终端根据该特定逻辑信道的SDU数据量在该MAC PDU结构中组装该特定逻辑信道的待传输数据可以包括如下几种情况:
一种可能实现方式中,若该终端确定该待传输数据的数据量大于该特定逻辑信道的SDU的数据量,则该终端在该MAC PDU结构中组装该特定逻辑信道的有效待传输数据构成该MAC PDU,该有效待传输数据的数据量等于该特定逻辑信道的SDU的数据量,该有效待传输数据包含于该待传输数据;若该终端确定该待传输数据的数据量小于该特定逻辑信道的SDU的数据量,则该终端将该待传输数据在该特定逻辑信道的SDU结构中进行重复组装,并将该特定逻辑信道的SDU组装构成该MAC PDU。比如,该终端根据配置信息获取到的该特定逻辑信道的SDU的数据量为9个字节,而该特定逻辑信道的待传输数据的数据量为10个字节,则该终端从该待传输数据中取9个字节作为有效待传输数据组装在该MAC PDU中,剩下的1个字节则需要在下一个传输机会再发送;若该特定逻辑信道的待传输数据的数据量为5个字节,则该终端将该5个字节先组装在该特定逻辑信道的SDU中,然后将待传输数据的5个字节中选择前4个字节继续组装在该特定逻辑信道的SDU中,然后将该特定逻辑信道的SDU组装构成该MAC PDU。
另一种可能实现方式中,本实施例中,该终端在组装该MAC PDU时也还可以采用如下方案:
当该终端确定该特定逻辑信道的数目为大于1的整数时,该终端按照特定规则和该特定逻辑信道的SDU的数据量在该MAC PDU结构中组装待传输数据构成该MAC PDU。其中该特定规则为将该特定逻辑信道对应的SDU按照该特定逻辑信道对应的逻辑信道标识ID从小到大的顺序在该MAC PDU结构中进行组装;或,该特定规则为将该特定逻辑信道对应的SDU按照该特定逻辑信道对应的逻辑信道ID从大到小的顺序在该MAC PDU结构中进行组装;或,该特定规则为将该特定逻辑信道对应的SDU按照预定顺序在该MAC PDU结构中进行组装,该预定顺序由该网络设备确定或协议规定。比如,当该特定逻辑信道的数目为4,分别为逻辑信道1,逻辑信道2,逻辑信道4和逻辑信道5时,该终端可以将各逻辑信道按照逻辑信道ID由小到大的顺序在该MAC PDU结构中组装各逻辑信道的SDU,即如图5所示,以左侧为头,则由左至右的顺序为逻辑信道1的SDU1,逻辑信道2的SDU2,逻辑信道4的 SDU4和逻辑信道5的SDU5。当然该终端也可以将各逻辑信道按照逻辑信道ID由大到小的顺序在该MAC PDU结构中组装各逻辑信道的SDU,如图6所示,以左侧为头,则由左至右的顺序为逻辑信道5的SDU5,逻辑信道4的SDU4,逻辑信道2的SDU2和逻辑信道1的SDU1。当然该终端也可以将各逻辑信道按照逻辑信道ID由网络设备或协议规定的顺序在该MAC PDU结构中组装各逻辑信道的SDU,比如如图7所示,以左侧为头,则由左至右的顺序为逻辑信道5的SDU5,逻辑信道2的SDU2,逻辑信道1的SDU1和逻辑信道4的SDU4。此处仅是给出了三种可能的实现方式,但在实际应用中,并不限定该三种可能实现方式,只要可以让终端可以完成MAC PDU的组装即可。
另一种可能实现方式中,本实施例中,该终端在组装该MAC PDU时也还可以采用如下方案:
当该终端确定该特定逻辑信道的数目为大于1的整数时,该终端在该MAC PDU结构中为该特定逻辑信道SDU添加对应的子头,且该子头中仅包含长度字段,该长度字段用于指示该特定逻辑信道的数据量。比如,如图8所示,以左侧为头,则由左至右的顺序为逻辑信道5的子头5,逻辑信道5的SDU,逻辑信道2的子头2,逻辑信道2的SDU,逻辑信道1的子头1,逻辑信道1的SDU,逻辑信道4的子头4和逻辑信道4的SDU,其中各逻辑信道的子头中包含有长度子段,用于指示各逻辑信道的SDU的数据量。当然由于逻辑信道4位于MAC PDU的最后,该逻辑信道4可以没有子头。
本实施例中,该终端在构造该MAC PDU中的过程中,上述几种可能实现方式可以综合采用也可以独立采用,具体的组合方式,此处不做限定。
403、终端将该MAC PDU发送给网络设备。
终端将组装好的MAC PDU发送给网络设备。
本实施例中,该终端根据特定逻辑信道的配置信息构造该MAC PDU并发送给网络设备。由于该终端网络设备可以根据该配置信息识别该特定逻辑信道,进而能够实现对该MAC PDU进行处理,实现了通信传输中的上下行数据传输。
具体情况如图9所示,本申请实施例中的数据处理方法的另一个实施例包括:

903、该数据发送设备按照现有规则在该MAC PDU结构中组装该特定逻辑信道的SDU和该MAC CE构成MAC PDU。
该数据发送设备按照该MAC CE在该MAC PDU结构中的组装位置比该特定逻辑信道的SDU在该MAC PDU结构中的组装位置靠前的规则将该MAC CE与该特定逻辑信道的SDU在该MAC PDU结构中进行组装。
904、该数据发送设备将该MAC PDU发送给数据接收设备。
该数据发送设备将组装完成的MAC PDU发送给数据接收设备。
本实施例中,该数据发送设备在该特定逻辑信道的优先级高于该数据发送设备待发送的全部MAC CE时,该数据发送设备将该特定逻辑信道的SDU和该MAC CE按照该特定逻辑信道与该MAC CE之间的优先级由高到低的顺序在该MAC PDU结构中组装构成该MAC PDU,这样可以保证该特定逻辑信道的SDU可以优先进行解包处理,有利于降低该特定逻辑信道的处理时延。
