网络设备可通过MAC控制元素(Control Element,CE)指示复制传输是否激活,和/或,复制传输中的RLC信息,如各个RLC实体是否激活。对于发送MAC CE的网络设备而言,其可能没有获取到其他网络设备下的RLC信息,这时MAC CE所指示的部分RLC信息是无意义的,导致终端设备依据该MAC CE所确定的复制传输是否激活,和/或,复制传输中的RLC信息不准确。
发明内容

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描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。针对本申请中的实施例,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。
如上所述,Rel-15的复制传输适用于CA场景或者DC场景,对于CA场景,支持数据复制传输(data duplication)的方案利用PDCP的复制数据功能,使相同的PDCP PDU分别传输到两个RLC实体(即两个不同的逻辑信道),并最终保证相同的PDCP PDU能 够在不同物理层聚合载波上传输,从而达到频率分集增益,以提高数据传输可靠性。如图1中的DRB 1和DRB 3,具体的,DRB1和DRB3对应的CA场景下的PDCP PDU被映射到两个RLC实体上,DRB1对应的两个RLC实体可以被映射到主小区组(Master Cell Group,MCG)中的不同的MAC实体上,DRB3对应的两个RLC实体可以被映射到辅小区组(Secondary Cell Group,SCG)中的不同的MAC实体上。对于DC场景,支持数据复制传输的方案利用PDCP的复制数据功能,使相同的PDCP PDU分别传输到两个RLC实体,两个RLC实体分别对应不同的MAC实体。如图1中的DRB2,具体的,DRB2对应的两个RLC实体分别可以被映射到MCG和SCG中的不同的MAC实体上。
在Rel-15中,网络设备可通过MAC CE指示复制传输处于激活态或者非激活态。该MAC CE也可以被称为复制激活/非激活MAC CE。应理解的是,在本申请中“复制传输处于激活态或者非激活态”指的是至少一个DRB对应的PDCP的复制数据功能处于激活态或者非激活态。
具体的,Rel-15中的MAC CE格式如图2所示,其中,一个八位字节的复制激活/去激活MAC CE由具有(Logic Channel Identifier,LCID)的MAC子头部标识。它有一个固定的大小,由一个包含八个D域的八位字节组成。对于MAC实体,复制激活/去激活MAC CE定义如下。
Di表示DRBi对应的PDCP的复制数据功能(即PDCP复制传输或复制传输)处于激活态或者非激活态,其中i是配置有PDCP复制传输、RLC实体和MAC实体对应的所有DRB中第i个DRB的标识。Di=1,表示DRBi的PDCP复制传输将被激活。Di=0,表示DRBi的PDCP复制传输被去激活。
Rel-16的复制传输适用于CA场景和/或DC场景,其中,相同的PDCP PDU可以被配置四个RLC实体。在Rel-16中,网络设备可通过MAC CE指示复制传输中的RLC信息。
可选的,RLC信息包括:复制传输中的至少一个RLC实体的标识,和/或,用于标识至少一个RLC实体是否处于激活态的标识。应理解的是,在本申请中“复制传输中的至少一个RLC实体的标识”指的是一个DRB对应的复制传输中的至少一个RLC实体的标识。
具体的,Rel-16中的MAC CE格式如图3所示,其中,该MAC CE用于指示复制传输中的RLC实体对应的PDCP复制传输处于激活或者非激活态,该MAC CE由具有LCID的MAC子头部标识。它有一个固定的大小,由一个包含八个D域的八位字节组成。该MAC CE包括:DRB ID和RLCi。
DRB ID表示上述MAC CE应用的DRB的标识。DRB ID的长度为5比特。
RLCi表示第i个RLC实体对应的PDCP复制传输的激活/非激活态,其中i是上述DRB对应的RLC实体中的第i个RLC实体的标识。RLCi=1,表示第i个RLC实体对应的PDCP复制传输将被激活。RLCi=0,表示第i个RLC实体对应的PDCP复制传输将被去激活。
综上,网络设备可通过MAC CE指示复制传输是否激活,和/或,复制传输中的RLC信息,如各个RLC实体是否激活。对于发送MAC CE的网络设备而言,这里的各个RLC实体可能包括其他网络设备下的RLC信息,因此,当发送MAC CE的网络设备没有获取到其他网络设备下的RLC信息时,该MAC CE所指示的这部分RLC信息是无意义的,导致终端设备依据该MAC CE所确定的复制传输是否激活,和/或,复制传输中的RLC信息不准确。从而造成数据传输可靠性低的问题。
基于上述技术问题,本申请提供一种无线通信方法、终端设备和网络设备。本申请的发明主旨是:复制传输中的MAC CE将存在不同的指示方式,终端设备将根据不同的指示方式来确定复制传输是否激活,和/或,复制传输中的RLC信息,以摒弃无意义的RLC信息。
本申请实施例可以应用于各种通信系统,例如: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)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
本申请实施例对应用的频谱并不限定。例如,本申请实施例可以应用于授权频谱,也可以应用于免授权频谱。
可选地,本申请实施例中的通信系统可以应用于CA场景,也可以应用于DC场景,还可以应用于CA和DC的结合场景。
示例性的,图4为本申请实施例提供的CA场景图,如图4所示,通信系统可以包括网络设备110和终端设备120,该网络设备110和终端设备120通过CA技术实现数据传输,该网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。

可选的,上述网络设备,如第一网络设备、第二网络设备或第三网络设备支持上述三种指示方式中的至少一种。
下面针对步骤S702进行详细阐述:
若上述MAC CE包括:第一网络设备的RLC信息,MAC CE的指示方式是上述第一指示方式,在这种情况下,MAC CE并不包括除第一网络设备之外的其他网络设备的RLC信息,即不存在无意义的RLC信息。因此,终端设备可以根据该MAC CE确定复制传输是否激活,和/或,复制传输中的RLC信息。例如:终端设备根据该MAC CE确定第一网络设备下的RLC实体1处于激活态,RLC实体2-4处于非激活态。
若上述MAC CE包括:至少一个第二网络设备的RLC信息,MAC CE的指示方式是上述第二指示方式,在这种情况下,MAC CE可能包括除第一网络设备之外的其他网络设备的RLC信息,即可能存在无意义的RLC信息。基于此,本申请提供至少如下两种可选方式,以使终端设备可以准确地确定复制传输是否激活,和/或,复制传输中的RLC信息。
可选方式一:第一网络设备或其他网络设备向终端设备发送指示信息,该指示信息用于指示是否忽略至少一个第三网络设备的RLC信息,即是否忽略非第一网络设备的RLC信息。若该指示信息指示忽略至少一个第三网络设备的RLC信息,表示终端设备即使获取到了DRB对应的至少一个第二网络设备的RLC信息,但是终端设备可以根据该指示信息摒弃掉至少一个第三网络设备的RLC信息(即无意义的RLC信息)。
需要说明的是,该指示信息可以上述第一指示信息,也可以是第二指示信息。
可选的,第二指示信息携带在RRC消息或者DCI消息中。
可选的,第二指示信息是RRC消息或者DCI消息中的新参数或者已有参数的新数值。
可选的,第二指示信息是第一网络设备发送的LCID或eLCID。具体的,按照不同的LCID的取值,理解不同的信息,即是否忽略,是否使用。示例性的,基于LCID的方式,也可以理解为基于MAC CE或MAC PDU信息的方式。
可选方式二:第一网络设备和其他网络设备之间经过通信或交互,获取到的RLC信息均是有意义的信息,基于该前提条件,MAC CE包括:至少一个第二网络设备的RLC信息都是有意义的RLC信息。因此,终端设备可以根据该MAC CE确定复制传输是否激活,和/或,复制传输中的RLC信息。
可选的,MAC CE包括:至少一个第三网络设备的RLC信息。MAC CE的指示方式是上述第三指示方式,在这种情况下,MAC CE包括的均是无意义的RLC信息,而假设终端设备预先获取到了至少一个第二网络设备的RLC信息。基于此,终端设备可以将至少一个第二网络设备的RLC信息中的无意义信息排除,以得到第一网络设备的RLC信息,因此,终端设备可以根据第一网络设备的RLC信息确定复制传输是否激活,和/或,复制传输中的RLC信息。
需要说明的是,以上阐述的是针对收到一个MAC CE的复制传输的情况,下面将针对复制传输中存在多个MAC CE的情况进行说明:
可选方式一:若MAC CE为多个,且多个MAC CE对应的DRB相同,但是多个MAC CE所指示的复制传输是否激活的信息不同,和/或,多个MAC CE所指示的复制传输的RLC信息不同,则终端设备根据多个MAC CE中的一个第一MAC CE和第一MAC  CE的指示方式,确定复制传输是否激活,和/或,复制传输中的RLC信息。
可选的,第一MAC CE是根据预设规则在多个MAC CE中选择得到的MAC CE。
可选的,第一MAC CE是来自主节点的MAC CE或对应MCG的MAC CE;或者,第一MAC CE是来自辅节点的MAC CE或对应SCG的MAC CE。即上述的预设规则是将来自主节点的MAC CE或对应MCG的MAC CE作为第一MAC CE。或者,将来自辅节点的MAC CE或对应SCG的MAC CE作为第一MAC CE。也就是说,当指示信息不同时,以特定节点的指示信息为准。
可选的,主节点指的是PCell对应的基站,辅节点指的是PSCell对应的基站。
示例性的,若复制传输中存在两个MAC CE,如MAC CE1和MAC CE2,且两个MAC CE对应的DRB相同,也就是说,两个MAC CE均是用于指示相同DRB对应的复制传输处于激活态或者非激活态,和/或,用于指示相同DRB对应的复制传输中的RLC信息。基于此,终端设备以MAC CE1和MAC CE1的指示方式,确定复制传输是否激活,和/或,复制传输中的RLC信息。或者,终端设备以MAC CE2和MAC CE2的指示方式,确定复制传输是否激活,和/或,复制传输中的RLC信息。
可选方式二:若MAC CE为多个,且多个MAC CE对应的DRB相同,但是多个MAC CE所指示的复制传输是否激活的信息不同,和/或,多个MAC CE所指示的复制传输的RLC信息不同,则终端设备根据第二MAC CE和第二MAC CE对应的指示方式,确定复制传输中的第二MAC CE对应的RLC信息。也就是说,当指示信息不同时,以对应节点的指示信息为准。
可选的,第二MAC CE是来自RLC实体所对应的节点的MAC CE或者RLC实体所在的小区组(Cell Group,CG)对应的MAC CE。
应理解的是,第二MAC CE对应的RLC信息指的是用于发送第二MAC CE的网络设备或节点的RLC信息,或者,用于发送第二MAC CE的网络设备或节点所在的CG中的RLC信息。
示例性的,若复制传输中存在两个MAC CE,如MAC CE1和MAC CE2,且两个MAC CE对应的DRB相同,也就是说,两个MAC CE均是用于指示相同DRB对应的复制传输处于激活态或者非激活态,和/或,用于指示相同DRB对应的复制传输中的RLC信息。基于此,终端设备确定上述复制传输对应的RLC实体分别对应于哪个节点,假设存在两个RLC实体,分别是RLC实体1和RLC实体2,RLC实体1对应的节点是节点1,RLC实体2对应的节点是节点2。节点1发送的MAC CE1指示RLC实体1处于激活态,RLC实体2处于激活态,则终端设备认为RLC实体1,2激活。而后,节点2发送MAC CE2,指示RLC实体1处于非激活态,RLC实体2处于非激活态。基于此,终端设备则认为RLC实体1处于激活态,且RLC实体2处于非激活态。
示例性的,若复制传输中存在两个MAC CE,如MAC CE1和MAC CE2,且两个MAC CE对应的DRB相同,也就是说,两个MAC CE均是用于指示相同DRB对应的复制传输处于激活态或者非激活态,和/或,用于指示相同DRB对应的复制传输中的RLC信息。基于此,终端设备确定上述复制传输对应的RLC实体分别对应于哪个CG,假设存在两个RLC实体,分别是RLC实体1和RLC实体2,RLC实体1对应的MCG,RLC实体2对应的SCG,MCG中的节点发送的MAC CE1指示RLC实体1处于激活态,RLC实体2处于激活态。,则终端设备认为RLC实体1,2激活。而后,SCG中的节点发送MAC CE2,指示RLC实体1处于非激活态,RLC实体2处于非激活态。基于此,终端设备则认为RLC实体1处于激活态,且RLC实体2处于非激活态。
综上,在本申请中,终端设备可以根据复制传输中的MAC CE和MAC CE的指示方式,确定复制传输是否激活,和/或,复制传输中的RLC信息。例如:当MAC CE指示方式指示MAC CE包括发送该MAC CE的网络设备的RLC信息时,这种情况则不存在无意义的RLC信息。当MAC CE指示方式指示MAC CE包括DRB对应的所有第二网络 设备的RLC信息时,这种情况可能存在无意义的RLC信息,但是在本申请中,第一网络设备可以预先获取到其他网络设备的RLC信息,或者,终端设备可以通过第一指示信息或者第二指示信息忽略无意义的RLC信息。当MAC CE指示方式指示MAC CE包括:至少一个第三网络设备的RLC信息,即包括无意义的RLC信息,而终端设备可以预先获取到了DRB对应的所有网络设备的RLC信息。基于此,终端设备可以将所有网络设备的RLC信息中的无意义信息排除,从而使得终端设备能够准确地确定复制传输是否激活,和/或,复制传输中的RLC信息。
