Description

关闭、开启数据包汇聚协议包复制功能的方法及装置 技术领域
本公开涉及通信技术领域,尤其涉及一种关闭、开启数据包汇聚协议包复制功能的方法及装置、发送媒体接入控制控制元素的方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
目前,第三代合作伙伴计划(3rd Generation Partnership Project,简称为3GPP)正在展开关于第五代移动通信技术(5th Generation,简称为5G)新空口(new radio,简称为NR)的标准化工作,为了解决数据包或信令包传输的可靠性问题,3GPP已经通过了在用户面数据包汇聚协议(packet data convergence protocol,简称为PDCP)层的包复制方案。但由于PDCP层位于无线用户面协议栈最上层,PDCP包和PDCP复制包无法保证能够通过底层的两个载波来发送,这就带来一个问题:如果一个载波上的信号质量非常差且PDCP包和PDCP复制包均在该载波上发送,则发送成功的概率会很低。为了解决该问题,相关会议上提出了PDCP层包复制与载波结合的方案,通过建立承载分离(split bear),也即在PDCP层以下将一个承载映射到两个或多个无线链路控制(RLC)实体上,从而可以将一个PDCP层映射到不同的逻辑信道上,进而可以实现将PDCP包和PDCP复制包映射到不同的物理载波上发送。
之后,3GPP会议上通过了采用媒体接入控制(MAC)控制元素(Control Element,简称为CE)来更加快速地控制开启关闭PDCP包复制功能的方法,同时通过了无线资源控制(Radio Resource Control,简称为RRC)层可以将PDCP包复制对应的两个逻辑信道映射到不同的载波上。
然而,当用户设备(UE)的一个载波去激活后,如果开启PDCP包复制功能的数据承载(DRB)或信令承载(SRB)的一个逻辑信道映射在该载波上,且该逻辑信道没有配置新的载波,那么该逻辑信道上的数据包将无法发送。

具体实施方式
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
图1是本申请一示例性实施例示出的一种关闭PDCP包复制功能的方法的流程图,该实施例从UE侧进行描述,如图1所示,关闭PDCP包复制功能的方法包括:
在步骤S101中,接收基站发送的至少一个MAC CE,该MAC CE携带目标载波信息。
在该实施例中,UE接收基站发送的至少一个MAC CE可以包括但不局限于:UE可以接收基站发送的一个MAC CE,例如接收基站发送的第一MAC CE。UE也可以接收基站发送的两个MAC CE,例如接收基站发送的第一MAC CE和第二MAC CE。UE还可以接收基站发送的三个MAC CE,例如接收基站发送的第一MAC CE、第三MAC CE和第四MAC CE。
其中,第一MAC CE用于指示UE去激活目标载波。第二MAC CE的数量等于所有映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的数量,每个第二MAC CE分别用于指示关闭一个DRB或SRB的PDCP包复制功能。第三MAC CE和第四MAC CE的数量之和等于所有映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的数量,每个第三MAC CE分别用于指示关闭一个DRB或SRB的PDCP包复制功能,每个第四MAC CE分别用于指示一个DRB或SRB的逻辑信道所映射的载波由目标载波更新为处于激活状态的新载波。
在步骤S102中,根据该MAC CE,关闭映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能。
若UE接收基站发送的第一MAC CE,并根据第一MAC CE关闭所有映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能。
若UE接收基站发送的第一MAC CE和第二MAC CE,则可以根据第一MAC CE和第二MAC CE,关闭所有映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能。
可选地,在关闭所有映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能时,还可以确定与目标载波对应的RLC实体,清除所有待发送的RLC实体的SDU和PDU,并重置与RLC实体对应的定时器和状态变量。其中,状态变量可以包括但不局限于维护发送窗口下边界与上边界的位置的状态变量。
若UE接收基站发送的第一MAC CE、第三MAC CE和第四MAC CE,则可以根据第一MAC CE和第三MAC CE,关闭映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的与第三MAC CE同数量的DRB或SRB的PDCP包复制功能。
假设,目标载波为载波1,共有10个开启PDCP包复制功能的DRB与载波1相对应,UE接收到8个第三MAC CE,2个第四MAC CE,则UE关闭8个DRB的PDCP包复制功能,其中,关闭掉的这8个DRB与8个第三MAC CE中携带的DRB相对应。
由此可见,该实施例可以通过多种方式关闭映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能,实现方式灵活多样。
上述实施例,通过接收基站发送的至少一个MAC CE,并根据该MAC CE中携带的目标载波信息关闭映射在目标载波对应的逻辑信道上且开启PDCP包复制功能的DRB或SRB的PDCP包复制功能,以解决去激活目标载波对应的逻辑信道上的数据包无法发送问题。

在步骤S201中,接收基站发送的第五MAC CE,第五MAC CE用于指示UE激活目标载波。
在去激活目标载波之后,如果基站想激活目标载波,则可以向UE发送第五MAC CE。
在步骤S202中,根据第五MAC CE,开启所有映射在目标载波对应的逻辑信道上且 关闭PDCP包复制功能的DRB或SRB的PDCP包复制功能。
上述实施例,通过根据接收的第五MAC CE开启所有映射在目标载波对应的逻辑信道上且关闭PDCP包复制功能的DRB或SRB的PDCP包复制功能,使得UE在激活目标载波之后,可以开启映射在对应DRB或SRB的PDCP包复制功能,从而可以发送目标载波对应的逻辑信道上的数据包。

在步骤S302中,根据第六MAC CE,开启目标DRB或目标SRB的PDCP包复制功能。
在该实施例中,在开启目标DRB或目标SRB的PDCP包复制功能之后,PDCP层可以对PDCP包进行复制,并通过对应的逻辑信道来发送。
上述实施例,通过根据接收的第六MAC CE来开启目标DRB或目标SRB的PDCP包复制功能,从而可以通过两个逻辑信道来发送PDCP包和PDCP复制包。

其中,一个逻辑信道可以作为主逻辑信道,用于收发原始PDCP包,另一个逻辑信道作为辅助逻辑信道,用于收发复制的PDCP包。
在步骤S304中,根据RRC消息,将目标DRB或目标SRB的PDCP包复制功能设置为未开启状态,以及配置目标DRB或目标SRB的两个逻辑信道与载波的映射关系。
上述实施例,通过根据接收的RRC消息,将目标DRB或目标SRB的PDCP包复制功能设置为未开启状态,并配置目标DRB或目标SRB的两个逻辑信道与载波的映射关系,从而为后续开启目标DRB或目标SRB的PDCP包复制功能提供条件。
