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。
本申请实施例的技术方案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、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、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、非授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频谱上的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)、未来的5G系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如设备到设备(Device to Device,D2D)通信、机器到机器(Machine to Machine,M2M)通信、机器类型通信(Machine Type Communication,MTC)、以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
本申请实施例中的网络设备或网络节点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(例如UE)进行通信。可选地,该网络设备可以是GSM系统或CDMA系统中 的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
本申请实施例中的终端设备可以是移动的或固定的。可选地,所述终端设备可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景和/或双连接(Dual Connectivity,DC)场景中。
在DC场景下,多个小区组(Cell Group,CG)可以为终端设备服务,该多个CG例如可以包括主CG(Master CG,MCG)或者辅CG(Secondary CG,SCG),也可以称为主基站或者辅基站。如图1所示,图1中的终端设备130周围的网络设备包括主基站110和至少一个辅基站120。至少一个辅基站120分别与主基站110相连,构成多连接,并分别与终端设备130连接为其提供服务。
主基站110可以为LTE网络,辅基站120可以为NR网络;或者,主基站110可以为NR网络,辅基站120可以为LTE网络;或者,主基站110和辅基站120都为NR网络。此外,主基站110还可以为GSM基站、CDMA基站等,辅基站120也可以为GSM基站、CDMA基站等,这里对主基站110和辅基站120均不做任何限定。
终端设备130可以通过主基站110和辅基站120同时建立连接。终端设备130和主基站110建立的连接为主连接,终端设备130与辅基站120建立的连接为辅连接。终端设备130的控制信令可以通过主连接进行传输,而终端设备的数据可以通过主连接和辅连接同时传输,也可以只通过辅连接进行传输。
主基站和辅基站,与终端设备之间可以进行复制数据的传输,复制数据传输的方式采用的是DC或者分叉承载(split bearer)的协议架构。例如图2所示,PDCP实体1可以将分组数据汇聚协议(Packet Data Convergence Protocol)PDCP PDU复制为相同的两份,比如一个是PDCP PDU,一个是复制的PDCP PDU(Duplicated PDCP PDU),两个PDCP PDU分别经过无线链路控制(Radio Link Control,RLC)实体1和RLC实体2传输至媒体接入控制(Media Access Control,MAC)实体1和MAC实体2,并经过MAC实体1和MAC实体2分别到达不同CG,即MCG和SCG。之后经过空口到达终端设备(下行)或者基站(上行)相应的MAC实体以及RLC实体,最后再汇聚到PDCP实体。
在CA场景下,例如图3所示,PDCP实体1可以将一个PDCP协议数据单元(Protocol Data Unit,PDU)复制成两份,分别映射到RLC实体1和RLC实体2,并通过一个MAC实体1映射到两个不同的载波单元(Component Carrier,CC)(也简称为载波)上,从而达到频率分集增益以提高数据传输的可靠性。
在图4所示的复制数据传输的架构中,可以为一个终端设备同时配置DC和CA的复制数据传输,PDCP实体1下的RLC实体1和RLC实体2均对应于MAC实体1,PDCP实体3下的RLC实体1和RLC实体2均对应于MAC实体2。而PDCP实体2下的RLC实体1和RLC实体2分别对应于MAC实体1和MAC实体2。其中MAC实体1对应MCG,MAC实体2对应SCG。
数据复制在PDCP层进行,相同的PDCP PDU分别映射到不同的RLC实体(RLC entity)。数据复制传输,也即PDCP复制传输。MAC层需要将不同RLC实体的复制数据传输到不同的载波。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,使复制的PDCP PDU分别传输到两个RLC实体,即两个不同的逻辑信道,并最终保证复制的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,例如图4中的数据无线承载(Data Radio Bearer,DRB)1和DRB 3所示。对于DC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,使复制的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。,例如图4中的DRB 1和DRB 2所示。
为了充分利用双连接场景和CA场景下的复制数据以获得更高的资源使用率和数据传输的可靠性,本申请实施例中,DC场景和CA场景下的复制数据可以结合以引入多于两个副本的复制数据机制,即一个PDCP实体可以对应于多于2个RLC实体。例如图5所示,假设PDCP实体对应四个RLC实体,即RLC实体1、RLC实体2、RLC实体3和RLC实体4。这4个RLC实体分别对应逻辑信道1、逻辑 信道2、逻辑信道3和逻辑信道4。基于PDCP服务数据单元(Service Data Unit,SDU)得到的PDCP PDU,可以通过这4个逻辑信道传输。其中,逻辑信道2用于传输PDCP PDU,逻辑信道3用于传输DC下复制的PDCP PDU,逻辑信道1和逻辑信道4用于传输CA下复制的PDCP PDU。逻辑信道1和逻辑信道2为MCG的逻辑信道,逻辑信道3和逻辑信道4为SCG的逻辑信道。逻辑信道1传输的复制的PDCP PDU和逻辑信道2传输的PDCP PDU通过MAC实体1映射至物理载波1和物理载波2。逻辑信道3传输的复制的PDCP PDU和逻辑信道4传输的复制的PDCP PDU通过MAC实体2映射至物理载波3和物理载波4。这样,复制的PDCP PDU就能够在4个物理载波上进行传输,实现了更高的资源使用率和数据传输的可靠性。
目前,针对CA或DC的复制数据传输,引入了逻辑信道到小区的限制(LCH-to-Cell restriction)的概念,以使不同逻辑信道(Logical Channel,LCH)上的数据仅在特定的载波进行传输。例如,在逻辑信道配置时,配置该逻辑信道所允许映射或者使用的服务小区(allowedServingCells)的标识,根据该标识,当终端设备收到上行授权(UL grant)信息时,可以根据该上行授权信息所在的载波的标识,确定当前有待传输数据的逻辑信道的数据,是否可以在该上行授权信息指示的上行资源上传输。本申请实施例中为逻辑信道配置的allowedServingCells,也即该逻辑信道所允许使用的载波。若配置的该逻辑信道所允许使用的载波与该上行资源所在的载波匹配,则该逻辑信道的数据可以利用该上行资源传输给网络。对于每个逻辑信道,仅配置一套所允许使用的载波。
但是,当逻辑信道的激活/去激活的状态发生变化时,例如激活的逻辑信道的数量增加或减少时,终端设备则无法更好地利用载波资源进行数据传输。
本申请实施例提供了一种基于复制数据传输的方案,能够在逻辑信道的激活/去激活的状态发生变化时,仍有效地利用载波资源传输各逻辑信道的数据,以保证业务能够及时和高质量地传输给网络设备。
以下,所述的逻辑信道的激活/去激活也指所述逻辑信道对应的RLC实体的激活/去激活,所述的载波也可以指小区,即服务小区(serving cell)。
图6是本申请一个实施例的基于复制数据传输的方法600的流程交互图。该方法可以由终端设备和网络设备执行。如图6所示,该方法600包括:
在610中,网络设备向终端设备发送上行授权信息。
在620中,终端设备接收网络设备发送的所述上行授权信息。
其中,该上行授权信息用于指示上行资源。
在630中,所述网络设备发送第一指示信息。
在640中,终端设备接收网络设备发送的所述第一指示信息。
其中,所述第一指示信息用于指示终端设备的至少一个逻辑信道的数据,是否能够使用所述上行授权信息指示的上行资源进行传输。
该实施例中,网络设备通过向终端设备发送第一指示信息,指示当前配置或激活的各逻辑信道的数据是否能够使用上行授权信息指示的上行资源,即上行共享信道(UL-Shared CHannel,UL-SCH)进行传输,从而在逻辑信道的激活/去激活的状态发生变化时,仍能够有效地利用载波资源传输各逻辑信道的数据。
其中,所述第一指示信息例如用于指示每个承载对应的逻辑信道是否能够使用所述上行授权信息指示的上行资源;或者用于指示每个用于复制数据传输的承载对应的逻辑信道是否能够使用所述上行授权信息指示的上行资源。所述上行授权例如包括CG和/或动态授权(dynamic grant)。
所述第一指示信息例如可以承载于下行控制信息(Download Control Information,DCI)、RRC消息、或者媒质访问控制控制元素(Media Access Control Controls Elements,MAC CE)中。
所述的RRC消息例如为RRC配置信息,比如可以是配置授权配置(Configured-Grantconfig)信息等。
其中,第一指示信息可以与上行授权信息携带于同一消息中,也可以携带于不同消息中。
例如,在动态调度(Dynamic Grant,DG)中,第一指示信息和上行授权信息可以均携带于DCI中。终端设备接收到该DCI后,从中获取该上行授权信息指示的上行资源以及第一指示信息,从而根据第一指示信息确定当前配置或激活的逻辑信道的数据是否能够使用该DCI调度的该上行资源传输给网络设备。
又例如,在配置授权(Configured Grant,CG)中,第一指示信息和上行授权信息可以均携带于RRC消息中,该RRC消息中携带网络设备为终端设备配置的上行资源以及该第一指示信息。终端设备接收到该RRC消息后,获取上行资源以及第一指示信息,从而根据第一指示信息确定当前配置或激活的逻辑信道的数据是否能够使用该上行资源传输给网络设备。
又或者,在配置授权中,上行授权信息可以携带于RRC消息中,而第一指示信息携带于DCI中, 其中该DCI用于激活或者去激活该RRC消息指示的上行资源。
在630和640中,所述第一指示信息用于指示终端设备的至少一个逻辑信道所允许使用的载波,其中,本申请对所述至少一个逻辑信道不做任何限定。
例如,所述逻辑信道可以是配置了或未配置复制数据传输功能的承载对应的逻辑信道,或者是复制数据传输功能激活或去激活的承载对应的逻辑信道。
又例如,所述至少一个逻辑信道的数量可以是:
一个承载支持的逻辑信道的最大数量,即不限于该终端设备,一个承载可能支持的逻辑信道的最大数量;或者,
所述终端设备的一个承载支持的逻辑信道的最大数量;或者,
网络设备为所述终端设备配置的一个承载对应的逻辑信道的最大数量;或者,
网络设备为所述终端设备配置的用于复制数据传输的一个承载对应的逻辑信道的最大数量;或者,
所述网络设备为所述终端设备配置的全部承载对应的逻辑信道的总数。
又例如,所述至少一个逻辑信道的数量为:
网络设备为所述终端设备配置的一个小区组(CG)关联的全部承载对应的逻辑信道的数量,比如以图4中的MCG为例,MCG关联的全部承载对应的逻辑信道包括DRB 1下的LCH 1(对应DRB 1的RLC实体1)、DRB 1下的LCH 2(对应DRB 1的RLC实体2)、DRB 2下的LCH 1(对应DRB 2的RLC实体1)、以及DRB 2下的LCH 2(对应DRB 2的RLC实体2);或者,
所述网络设备为所述终端设备配置的一个CG下的全部的逻辑信道的数量,比如MCG下的逻辑信道的总数或SCG下的逻辑信道的总数,以图4中的MCG为例,MCG下的全部的逻辑信道包括DRB 1下的LCH 1、DRB 1下的LCH 2、以及DRB 2下的LCH 1;或者,
所述终端设备在一个CG内支持的逻辑信道的最大数量;或者,
所述网络设备为所述终端设备配置的一个CG下的用于复制数据传输的一个承载对应的逻辑信道的最大数量;或者,
所述网络设备为所述终端设备配置的一个CG下的用于复制数据传输的所有承载对应的逻辑信道的最大数量;或者,
所述网络设备为所述终端设备配置的一个CG下的逻辑信道的最大数量,其中,网络设备为所述终端设备配置的一个CG下的逻辑信道的最大数量小于或等于所述终端设备在一个CG内支持的逻辑信道的最大数量。
其中,用于复制数据传输的承载可以是指配置了复制数据传输功能的承载,和/或,复制数据传输功能激活的承载。
本申请实施例对该第一指示信息的内容和格式不做任何限定。例如可以采用逻辑信道标识显示指示的方式,或者比特图(bitmap)指示的方式。
在第一种实现方式中,所述第一指示信息包括能够使用所述上行资源传输其数据的逻辑信道的逻辑信道标识,或者包括不能够使用所述上行资源传输其数据的逻辑信道的逻辑信道标识。
例如,如果DRB 1下的LCH 1、LCH 2、LCH 3和LCH 4中,LCH 1和LCH 2上的数据可以使用上行授权信息指示的上行资源传输,则该第一指示信息中包括LCH 1和LCH 2的逻辑信道标识。进一步地,还可以包括小区组标识(cell group id)。
在第二种实现方式中,所述第一指示信息包括多个比特,其中每个比特对应于一个逻辑信道,所述每个比特的值表示所述每个比特对应的逻辑信道的数据是否能够使用所述上行资源进行传输。
所述第一指示信息占用多个比特位,或者说,所述第一指示信息由多个比特位承载。其中,当比特位上的取值不同时,分别表示该比特位对应的逻辑信道的数据可以或不可以使用所述上行资源所在的载波进行传输。
例如,当某个比特位上的值为1时,可以认为该比特位对应的逻辑信道的数据可以使用所述上行资源所在的载波进行传输,为0时则表示不可以使用。例如,如果DRB 1下的LCH 1、LCH 2、LCH 3和LCH 4中,LCH 1和LCH 2上的数据可以使用上行授权信息指示的上行资源传输,则该第一指示信息中可以包括4个比特位,其中这4个比特位从前至后依次对应于逻辑信道1至逻辑信道4,那么这4个比特位应为1100。
该比特图包括N个比特位,N可以是网络设备配置的一个承载对应的逻辑信道的最大数量,并且该N个比特位可以同时指示多个承载对应的各逻辑信道的载波使用情况。或者,N可以是网络设备配置的用于复制数据传输的一个承载对应的逻辑信道的最大数量,且该N个比特可以同时指示多个配置或激活复制数据传输功能的承载对应的各逻辑信道的载波使用情况。例如,N可以等于630和640中的所述至少一个逻辑信道的数量。
举例来说,如图7所示,在DRB 1、DRB 2和DRB 3中,为DRB 1配置的逻辑信道的数量最大,为4个逻辑信道,因此N=4。当4个比特位为1000时,表示DRB 1的LCH 1(对应DRB 1的RLC实体1)、DRB 2的LCH 1(对应DRB 2的RLC实体1)、和DRB 3的LCH 1(对应DRB 2的RLC实体1)的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道的数据不可以使用。当4个比特位为0100时,表示DRB 1的LCH 2(对应DRB 1的RLC实体2)、DRB 2的LCH 2(对应DRB 2的RLC实体2)上的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。其中,可选地,当4个比特位为0100时,由于DRB 3没有配置复制数据传输功能,或者配置了复制数据传输功能但是未激活,即不存在LCH 2,则可以默认DRB 3的数据不能够使用所述上行资源进行传输。
又如,在图7中,N可以是网络设备配置的用于复制数据传输的一个承载对应的逻辑信道的最大数量。由于图7中所示的DRB 1和DRB 2是配置或激活复制数据传输功能的承载,且为DRB 1配置的逻辑信道的数量最大,为4个逻辑信道,因此N=4。当4个比特位为1000时,表示DRB 1的LCH的数据和DRB 2的LCH 1的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。当4个比特位为0100时,表示DRB 1的LCH 2的数据和DRB 2的LCH 2的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道的数据不可以使用。
另外,可选地,所述第一指示信息可以用于指示激活和/或使用的逻辑信道上的数据是否能够使用所述上行资源进行传输,即不指示未激活的逻辑信道是否能够使用所述上行资源进行传输。例如,若DRB 2下的LCH 2未激活,则第一指示信息所指示的逻辑信道中并不包括该LCH 2。
或者,如果某个承载上的某个逻辑信道未激活,则即使第一指示信息指示了该逻辑信道的数据能够使用所述上行资源进行传输,那么该逻辑信道的数据也不会使用所述上行资源进行传输。例如,如果图7中所示的DRB 2的LCH 2未激活,则即使第一指示信息指示LCH 2的数据可以使用该上行资源进行传输,LCH 2的数据也不会使用该上行资源进行传输。
又例如,在图7中,DRB 1、DRB 2和DRB 3下的逻辑信道的总数为4+3+1=8,因此可以N=8。例如,当8个比特位为1000 010 0时,表示DRB 1的LCH 1、DRB 2的LCH 2上的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。采用这种方式可以更加灵活地指示各个承载对应的各个逻辑信道的数据的上行资源使用情况,而不必使每个DRB的LCH 1上的数据的上行资源使用情况都相同,但是增加了比特开销。类似地,如果DRB 2的LCH 2未激活,则即使第一指示信息指示LCH 2的数据可以使用该上行资源进行传输,该LCH 2的数据也不可以使用该上行资源进行传输,即仅有DRB 1的LCH 1上的数据可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。
又或者,在图7中,配置了复制数据传输功能或者复制数据传输激活的承载为DRB 1和DRB 2,DRB 1和DRB 2下的逻辑信道的总数为4+3=7,因此可以N=7。例如,当7个比特位为1000 010时,表示DRB 1的LCH 1、DRB 2的LCH 2上的数据均可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。而对于未配置复制数据传输功能或者复制数据传输激活的承载,即DRB 3,由于仅有一个逻辑信道用来传输数据,因此该逻辑信道的数据可以使用任何载波进行传输,因此能够在该上行资源上进行传输;或者约定DRB 3的逻辑信道的数据不能够使用该上行资源进行传输。类似地,如果DRB 2的LCH 2未激活,则即使第一指示信息指示LCH 2的数据可以使用该上行资源进行传输,LCH 2的数据也不可以使用该上行资源进行传输,即仅有DRB 1的LCH 1上的数据可以使用该上行资源所在的载波进行传输,而其余逻辑信道不可以使用。
上述图7中所示的比特图的两种指示方式仅仅为示例,在实际使用中,N个比特位还可以具有其他的指示方式。例如,N可以是一个或多个承载对应的终端设备能够支持的逻辑信道的最大数量,或者网络设备为终端设备配置的逻辑信道的最大数量或实际数量;又例如,N可以是一个或多个小区组下,终端设备能够支持的逻辑信道的最大数量,或者网络设备为终端设备配置的逻辑信道的最大数量或实际数量。
对于DC场景下配置了复制数据传输的承载,例如可以按照先MCG后SCG的顺序,且每个CG按照逻辑信道索引的升序,依次对应N个比特位中从前至后或者从后至前的各个比特位。或者,对于每个配置了复制数据传输的承载,也按照先SCG后MCG的顺序,且每个CG按照逻辑信道索引的升序,依次对应N个比特位中从前至后或者从后至前的各个比特位。或者,对于DC场景下配置了复制数据传输的承载,例如可以按照先MCG后SCG的顺序,且每个CG按照逻辑信道索引的降序,依次对应N个比特位中从前至后或者从后至前的各个比特位。或者,对于每个配置了复制数据传输的承载,也按照先SCG后MCG的顺序,且每个CG按照逻辑信道索引的降序,依次对应N个比特位中从前至后或者从后至前的各个比特位。
该实施例中,所述第一指示信息可以是所述终端设备专属的指示信息。或者,该第一指示信息可以是针多个终端设备的公共的指示信息,例如,如果多个终端设备属于一个终端设备组,或者属于一个终端设备组类型,或者均配置授权,则可以通过一个第一指示信息指示该组终端设备各自的逻辑信道的数据是否能够使用各自的配置授权信息指示的上行资源传输。
可选地,在610之前,网络设备可以向终端设备发送RRC消息,所述RRC消息中包括所述至少一个逻辑信道所允许使用的载波的信息。相应地,所述终端设备接收该RRC消息。
举例来说,网络设备可以通过RRC消息,为终端设备配置复制数据传输的相关信息,其中包括与承载对应的逻辑信道标识、小区组标识等。同时,所述RRC消息可以指示复制数据传输的初始状态,以及该承载对应的每个逻辑信道允许映射的服务小区列表,即每个逻辑信道所允许使用的载波的列表。该列表至少可以用于该初始状态下的复制数据传输。比如,网络设备可以配置DRB 1为复制数据传输的承载,初始状态为去激活,且为CA和DC结合的架构。DRB 1下的逻辑信道包括LCH 1至LCH 4,其中LCH 1对应MCG且所允许使用的载波为CC 1和CC 2,LCH 2对应MCG且所允许使用的载波为CC 3和CC 4,LCH 3对应MCG且所允许使用的载波为CC 5和CC 6,LCH 4对应SCG且所允许使用的载波为CC 1和CC 2。网络设备可以配置DRB 2为不进行复制数据传输的承载,DRB 2下的逻辑信道所允许使用的载波为CC 1至CC 4。
终端设备根据该RRC消息,进行各个承载的复制数据传输的配置。当终端设备接收到网络设备发送的MAC CE,该MAC CE用于指示复制数据传输功能的激活或者去激活。如果该MAC CE指示了上述DRB 1的复制数据传输功能激活,则终端设备对DRB 1进行复制数据传输,相应地,终端设备根据为每个逻辑信道配置的所允许使用的载波,确定上行资源是否能够用于传输来自该逻辑信道的数据,比如,LCH 1的数据仅可以通过CC 1或CC 2传输,LCH 2的数据仅可以通过CC 3或CC 4传输,LCH 3的数据仅可以通过CC 5或CC 6传输。
之后,网络设备如果通过专用信令,例如承载于MAC CE的用于指示复制数据传输的状态变更的变更指示信息,则根据该变更指示信息对复制数据传输的状态进行变更。例如,以MCG为例,该变更指示信息指示MCG使用的逻辑信道由LCH 1、LCH 2和LCH 3变更为LCH 1和LCH 3,而SCG使用的逻辑信道不变。终端设备收到该变更指示信息后,根据该变更指示信息的指示,修改复制数据传输的状态,即,将MCG使用的逻辑信道由LCH 1、LCH 2和LCH 3变更为LCH 1和LCH 3。
此后,终端设备可以在接收到携带第一指示信息的DCI,或者携带该第一指示信息的配置授权信息(configuredGrantconfig)时,确定变更后的各个逻辑信道,即LCH 1和LCH 3是否可以使用相应的上行资源,在该上行资源所在的载波上进行传输。
应理解,终端设备可以根据第一指示信息,确定每个逻辑信道的数据是否能够使用上行授权信息指示的上行资源进行传输;或者,终端设备也可以根据所述每个逻辑信道所允许使用的载波的列表,即上述RRC消息指示的载波列表,确定每个逻辑信道所允许使用的载波,从而判断该逻辑信道的数据是否能够使用该上行资源进行传输。
也就是说,如果网络设备通过RRC消息为终端设备配置了逻辑信道所允许使用的载波的列表,且终端设备接收到了第一指示信息。则,一种实现方式中,终端设备可以根据该载波列表或该第一指示信息中的其中一个,例如根据该第一指示信息,确定是否能够使用该上行资源进行传输。另一种实现方式中,在接收到第一指示信息后,终端设备认为RRC配置的该载波列表失效。再一种实现方式中,对于第一指示信息对应的上行资源,例如携带第一指示信息的DCI调度的上行资源,终端设备可以根据该第一指示信息确定哪个逻辑信道的数据可以在该上行授权信息指示上行资源上传输,而对于其他上行资源,终端设备根据RRC配置的该载波列表确定哪个逻辑信道的数据可以在该上行资源上传输。
上面的描述的复制数据传输的配置、激活和变更,仅仅为示例。本申请实施例中所述的复制数据传输的状态发生变更,可以是:MCG使用的逻辑信道的数量增加、减少或变化;和/或,SCG使用的逻辑信道的数量增加、减少或变化;和/或,MCG使用的逻辑信道标识增加、减少或变化;和/或,SCG使用的逻辑信道标识增加、减少或变化。
本申请实施例中,上述的RRC消息中可以包括所述至少一个逻辑信道所允许使用的载波的信息。这些信息可以是针对所述承载进行配置,例如携带于无线承载配置(RadioBearerconfig)中;也可以针对逻辑信道进行配置,例如携带于逻辑信道配置(logicalchannelconfig)中。
在复制数据传输功能去激活时,每个CG仅有一个逻辑信道用于传输该承载的数据。该实施例中,可选地,所述终端设备的一个承载的复制数据传输功能去激活时可用的逻辑信道的数据,能够在任一载波上传输,即为其配置的逻辑信道到小区的限制(LCH-to-Cell restriction)失效或者没有为其配置逻辑信道到小区的限制(LCH-to-Cell restriction)。例如,假设上述DRB 1的复制数据传输功能去激活时可用的逻辑信道为LCH 1,则LCH 1上的数据可以在任一载波上传输。或者,可选地,终端设备的一个 承载的复制数据传输功能去激活时可用的逻辑信道的数据,仅在满足LCH-to-Cell restriction的载波上传输,即为其配置的LCH-to-Cell restriction仍然有效。
当然,该承载的复制数据传输功能去激活时可用的逻辑信道的数据是否能够在上行授权信息指示的上行资源上传输,也可以通过第一指示信息来确定。这时,第一指示信息也可以用于指示去激活时该承载对应的逻辑信道是否能够使用该上行资源进行传输。
应理解,由于一个承载的复制数据传输功能去激活时,该承载仅对应一个逻辑信道,因此该逻辑信道即为上述复制数据传输功能去激活时可用的逻辑信道。
如果第一指示信息采用比特图的方式实现,则对于没有配置复制数据传输功能的承载,例如可以通过比特图中的其中1位,比如最高位,来表示该承载对应的可用的该逻辑信道的数据是否能够使用所述上行资源所在的载波传输。
该实施例可以应用于复制数据传输的状态发生变更的情况下,例如激活的逻辑信道的数量发生变化时,激活的逻辑信道的标识发生变化时,复制数据传输功能从去激活变为激活时,复制数据传输功能从激活变为去激活时;也可以应用于初始的复制数据传输的配置,即网络设备为终端设备初始配置其逻辑信道所允许使用的载波;也可以应用于复制数据传输的状态不变,但是需要更新终端设备的逻辑信道所允许使用的载波。
例如,对于激活的逻辑信道的数量由多变少的情况,如果网络设备通过RRC消息为终端设备配置的一个CG下的全部逻辑信道均配置了所允许使用的载波,则当MAC CE中的变更指示信息指示该CG下可用的逻辑信道由多变少时,或者终端设备根据变更条件确定该CG下可用的逻辑信道由多变少时,仍可以沿用该RRC消息为当前逻辑信道所配置的所允许使用的载波,从而确定是否当前逻辑信道的数据是否可以使用该上行资源进行传输。而当该变更指示信息指示该CG下可用的逻辑信道由少变多时,则根据第一指示信息重新确定当前逻辑信道的数据是否可以使用该上行资源进行传输。
可选地,所述终端设备使用所述上行授权信息指示的所述上行资源,发送所述至少一个逻辑信道中的目标逻辑信道的数据,其中,所述目标逻辑信道所允许使用的载波与所述上行资源所在的载波匹配。
例如,如果目标逻辑信道所允许使用的载波为CC1、CC2、CC3,而该上行资源所在的载波为CC1,则该目标逻辑信道的数据能够在该上行资源上发送,网络设备可以通过第一指示信息向终端设备指示该目标逻辑信道的数据能够在该上行资源上发送。
应理解,本申请实施例中,目标逻辑信道所允许使用的载波与所述上行资源所在的载波匹配,包括两种情况。一种情况是,目标逻辑信道所允许使用的载波与所述上行资源所在的载波相同,例如目标逻辑信道所允许使用的载波为CC 1,所述上行资源所在的载波为CC 1。另一种情况是,目标逻辑信道所允许使用的多个载波中包括所述上行资源所在的载波,例如目标逻辑信道所允许使用的载波为CC 2、CC 2和CC 3,所述上行资源所在的载波为CC 1。上述两种情况都可以称为“匹配”,从而在该上行资源上发送该目标逻辑信道的数据。
进一步地,可选地,若所述上行资源所在的载波上的信道质量满足预设条件,所述终端设备使用所述上行资源,发送所述目标逻辑信道的数据。
也就是说,所述终端设备在接收到网络设备发送的第一指示信息,以指示该目标逻辑信道的数据能够在该上行资源上发送时,还需要判断该上行资源所在的载波上的信道质量是否满足预设条件,例如参考信号接收功率(Reference Signal Receiving Power,RSRP)大于RSRP阈值、或者参考信号接收质量(Reference Signal Receiving Quality,RSRQ)大于RSRQ阈值、或者信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)小于SINR阈值时,终端设备才使用所述上行资源,发送目标逻辑信道的数据。
图8是本申请另一实施例的基于复制数据传输的方法800的流程交互图。该方法可以由终端设备和网络设备执行。如图8所示,该方法800包括:
在810中,网络设备发送第一配置信息。
在820中,终端设备接收第一配置信息。
其中,所述第一配置信息用于指示终端设备的一个承载对应的多个逻辑信道集合所允许使用的载波,其中每个逻辑信道集合包括所述承载对应的逻辑信道中的至少部分逻辑信道。
在830中,所述终端设备根据所述第一配置信息,确定激活的或者使用的逻辑信道集合中的逻辑信道所允许使用的载波。
该实施例中,网络设备通过为终端设备的一个承载对应的多个逻辑信道集合分别配置所允许使用的载波。这样,终端设备在某个逻辑信道集合中的逻辑信道激活或者使用时,就能够知道这些逻辑信道所允许使用的载波,从而进行数据传输。
换句话说,网络设备可以配置多套逻辑信道到小区的限制(LCH-to-Cell restriction),其中每一套 LCH-to-Cell restriction可以应用于一个或多个逻辑信道集合。网络设备也可以针对一个逻辑信道集合配置一套或多套LCH-to-Cell restriction。
一个承载对应的多个逻辑信道中的各个逻辑信道可以有多种组合方式,每种组合方式形成一个逻辑信道集合,每个逻辑信道集合包括所述承载对应的逻辑信道中的至少部分逻辑信道。
换句话说,网络设备可以为所述多个逻辑信道集合分别配置多个逻辑信道到小区的限制(LCH-to-Cell restriction),即配置多套载波。
所述多个逻辑信道可以是网络设备为终端设备的该承载配置的逻辑信道,也可以是该承载所能够支持的最大数量的逻辑信道,或者所述多个逻辑信道的数量小于该承载所能够支持的逻辑信道的最大数量。
可选地,不同的逻辑信道集合中的逻辑信道的数量不同,和/或,不同的逻辑信道集合中的逻辑信道的逻辑信道标识不同。
网络设备可以为多个逻辑信道集合分别配置不同的多套载波,也可以为逻辑信道数量相同的逻辑信道集合配置相同的一套载波,即逻辑信道数量相同的逻辑信道集合所允许使用的载波相同。
例如,可以按照逻辑信道标识进行划分。网络设备为DRB 2配置了3个逻辑信道,即LCH 1、LCH 2和LCH 3。则在这3个逻辑信道中,可能的组合方式所形成的的逻辑信道集合分别为:LCH 1为逻辑信道集合1,LCH 1和LCH 2为逻辑信道集合2,LCH 1和LCH 3为逻辑信道集合3,LCH 2和LCH 3为逻辑信道集合4,LCH 1、LCH 2和LCH 3为逻辑信道集合5。网络设备可以通过第一配置信息为这5个逻辑信道集合分别配置5套载波。
这样,如果当前激活的逻辑信道,或者当前有待传输数据的逻辑信道为LCH 1和LCH 2,则终端设备可以根据第一配置信息确定网络设备为逻辑信道集合2中的LCH 1和LCH 2分别配置的所允许使用的载波。如果当前激活的逻辑信道,或者当前有待传输数据的逻辑信道为LCH 1、LCH 2和LCH 3,则终端设备可以根据第一配置信息确定网络设备为逻辑信道集合5中的LCH 1、LCH 2和LCH 3配置的所允许使用的载波。
又例如,可以按照逻辑信道数量进行划分。网络设备为DRB 2配置了3个逻辑信道,即LCH 1、LCH 2和LCH 3。LCH 1为逻辑信道集合1,LCH 1和LCH 2为逻辑信道集合2,LCH 1和LCH 3为逻辑信道集合3,LCH 2和LCH 3为逻辑信道集合4,LCH 1、LCH 2和LCH 3为逻辑信道集合5。其中,逻辑信道集合1中仅包括一个逻辑信道,为其配置一套载波;逻辑信道集合2、逻辑信道集合3和逻辑信道集合4中均包括2个逻辑信道,为这3个逻辑信道集合配置相同的一套载波;逻辑信道集合5中包括3个逻辑信道,为其配置一套载波。这样,网络设备通过第一配置信息为终端设备的DRB 1配置3套载波即可。
换一种理解,也可以将逻辑信道数量相同的逻辑信道集合认为是一个逻辑信道集合。例如,在上述LCH 1、LCH 2和LCH 3中,LCH 1为逻辑信道集合1(该逻辑信道集合仅包括1个逻辑信道),LCH 1和LCH 2的组合、LCH 1和LCH 3的组合以及LCH 1和LCH 3的组合均称为逻辑信道集合2(该集合包括2个逻辑信道),LCH 1、LCH 2和LCH 3为逻辑信道集合3(该集合包括3个逻辑信道)。网络设备可以通过第一配置信息为这3个逻辑信道集合分别配置3套载波。
这样,如果当前激活的逻辑信道,或者当前有待传输数据的逻辑信道的数量为1,则终端设备可以根据第一配置信息确定网络设备为逻辑信道集合1中的LCH 1配置的所允许使用的载波。如果当前激活的逻辑信道,或者当前有待传输数据的逻辑信道的数量为2,则终端设备可以根据第一配置信息确定网络设备为逻辑信道集合2中的各逻辑信道配置的所允许使用的载波。
应理解,当前有待传输数据的逻辑信道(即当前使用的逻辑信道)的数量小于当前激活的逻辑信道的数量时,按照当前使用的逻辑信道的数量确定逻辑信道集合。
该实施例中,该第一配置信息可以携带于针对承载的配置信息中,例如无线承载配置(RadioBearerconfig)中,也可以携带于针对逻辑信道的配置信息中,例如逻辑信道配置(logicalchannelconfig)中。
该实施例中,可选地,所述终端设备的一个承载的复制数据传输功能去激活时可用的逻辑信道的数据,能够在任一载波上传输,即为其配置的LCH-to-Cell restriction失效或没有为其配置LCH-to-Cell restriction。例如,假设上述DRB 1的复制数据传输功能去激活时可用的逻辑信道为LCH 1,即逻辑信道集合1,则LCH 1上的数据可以在任一载波上传输,即不为逻辑信道集合1配置LCH-to-Cell restriction,而只为逻辑信道集合2至逻辑信道集合5配置各自的所允许使用的载波;或者,LCH 1所允许使用的载波仍根据为逻辑信道集合1配置的LCH-to-Cell restriction确定,仅在满足网络设备为逻辑信道集合1配置的LCH-to-Cell restriction的载波上传输。
可选地,逻辑信道数量相同的逻辑信道集合所允许使用的载波可以相同或不同。
例如,网络设备为DRB 2配置了3个逻辑信道,即LCH 1、LCH 2和LCH 3。LCH 1和LCH 2组成的逻辑信道集合,与LCH 2和LCH 3组成的逻辑信道集合,这两个逻辑信道集合所允许使用的载波可以相同,也可以不同。
可选地,逻辑信道数量不同的逻辑信道集合所允许使用的载波也可以相同或不同。
例如,网络设备为DRB 2配置了3个逻辑信道,即LCH 1、LCH 2和LCH 3。其中,LCH 1和LCH 2组成的逻辑信道集合,与LCH 1、LCH 2和LCH 3组成的逻辑信道集合,这两个逻辑信道集合所允许使用的载波可以相同,也可以不同。
可选地,所述多个逻辑信道集合中包括第一逻辑信道集合和第二逻辑信道集合,所述第一逻辑信道集合中的至少一个逻辑信道与所述第二逻辑信道集合中的至少一个逻辑信道所允许使用的载波相同,其中,所述第一逻辑信道集合与所述第二逻辑信道集合中的逻辑信道数量相同或不同。
其中,网络设备为每个逻辑信道集合配置所允许使用的载波时,可以具体地为该逻辑信道集合中的各个逻辑信道配置所允许使用的载波。例如,在DRB 2下的LCH 1、LCH 2和LCH 3中,LCH 1为逻辑信道集合1,LCH 1和LCH 2为逻辑信道集合2,LCH 1和LCH 3为逻辑信道集合3,LCH 2和LCH 3为逻辑信道集合4,LCH 1、LCH 2和LCH 3为逻辑信道集合5。其中,网络设备可以为逻辑信道集合2中的LCH 1和LCH 2分别配置所允许使用的载波为CC 1和CC 2,并为逻辑信道集合3中的LCH 1和LCH 3分别配置所允许使用的载波为CC 1和CC 3。网络设备也可以逻辑信道集合2中的LCH 1和LCH 2分别配置所允许使用的载波为CC 1和CC 2,并为逻辑信道集合5中的LCH 1、LCH 2和LCH 3分别配置所允许使用的载波为CC 1、CC2和CC 3。
网络设备为每个逻辑信道集合配置所允许使用的载波时,还可以以逻辑信道集合为单位配置所允许使用的载波。例如,为逻辑信道集合2中的LCH 1和LCH 2配置所允许使用的载波分别为CC 1和CC 2,并为逻辑信道集合3中的LCH 1和LCH 3配置所允许使用的载波分别为CC 1和CC 3。终端设备使用不同的载波传输不同逻辑信道的数据,比如当前使用的逻辑信道为逻辑信道集合3,则使用CC 1传输LCH 1的数据,使用CC 3传输LCH 3的数据。
可选地,所述方法还包括:所述终端设备接收上行授权信息;所述终端设备使用所述上行授权信息指示的上行资源,发送所述承载对应的目标逻辑信道的数据,所述目标逻辑信道所允许使用的载波与所述上行资源所在的载波匹配。
例如,如果逻辑信道集合2中的LCH 2所允许使用的载波为CC 1,所述上行授权信息指示的上行资源所在的载波也为CC 1,则LCH 2可以作为该目标逻辑信道,并且LCH 2上的数据能够在该上行资源上发送。
又例如,如果逻辑信道集合2中的LCH 2所允许使用的载波中至少包括CC 1,所述上行授权信息指示的上行资源所在的载波也为CC 1,则LCH 2可以作为该目标逻辑信道,并且LCH 2上的数据能够在该上行资源上发送。
进一步地,可选地,若所述上行资源所在的载波上的信道质量满足预设条件,所述终端设备使用所述上行资源,发送所述目标逻辑信道的数据。
也就是说,所述终端设备在判断该目标逻辑信道的数据能够在该上行资源上发送时,还需要判断该上行资源所在的载波上的信道质量是否满足预设条件,例如RSRP大于RSRP阈值、或者RSRQ大于RSRQ阈值、或者SINR小于SINR阈值时,终端设备才使用所述上行资源,发送该目标逻辑信道的数据。
例如,当前激活的逻辑信道,或者当前有数据待传输的逻辑信道为逻辑信道集合2中的LCH 1和LCH 2。网络设备为逻辑信道2中的LCH 1和LCH 2分别配置所允许使用的载波为CC 1和CC 2,该上行授权信息指示的上行资源所在的载波为CC1,终端设备确定LCH 1上的数据能够在该上行资源上传输,并且确定CC1上的信道质量好到一定程度,才在该上行资源上发送LCH 1上的数据。
又例如,终端设备确定CC 1和CC 2上的信道质量较好,并且根据第一配置信息确定逻辑信道集合2中的LCH 1和LCH 2上的数据可以使用CC 1和CC 2进行传输,则终端设备使用LCH 1和LCH 2进行复制数据传输,且使用CC 1和CC 2在相应的上行资源上分别进行传输。
图9是本申请另一实施例的基于复制数据传输的方法900的流程交互图。该方法可以由终端设备和网络设备执行。如图9所示,该方法900包括:
在910中,终端设备在一个承载对应的激活的逻辑信道的数量发生变化时,确定所述承载下的至少一个逻辑信道所允许使用的载波。
该实施例中,终端设备可以在一个承载对应的激活的逻辑信道的数量发生变化时,按照预设规则重新确定所述承载对应的至少一个逻辑信道所允许使用的载波,从而有效地完成数据传输。
例如,在910中,若所述承载对应的激活的逻辑信道由M个逻辑信道变为N个逻辑信道且M大 于N,则所述终端设备可以将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,作为所述N个逻辑信道中的至少部分逻辑信道所允许使用的载波,M、N为正整数。
进一步地,可选地,所述终端设备可以将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,作为所述N个逻辑信道中特定逻辑信道所允许使用的载波中的一部分;或者,所述终端设备将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,平均地分配给所述N个逻辑信道中的各个逻辑信道,以作为所述N个逻辑信道中的各个逻辑信道所允许使用的载波中的一部分;或者,所述终端设备将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,平均地分配给所述N个逻辑信道中的K个逻辑信道,以作为所述K个逻辑信道中的各个逻辑信道所允许使用的载波中的一部分,K<N。
应理解,上面所述的将去激活的所述M-N个逻辑信道所允许使用的载波中的某个或某些载波(例如第一载波)分配给某个逻辑信道,可以是将所述第一载波增加至该逻辑信道所允许使用的载波中;或者,可以是使用所述第一载波替换该逻辑信道所允许使用的载波中的其他载波,即该逻辑信道所允许使用的载波变为该第一载波。
其中,所述至少一个逻辑信道为所述承载对应的逻辑信道中的至少部分。例如可以为所述承载对应的激活的逻辑信道的数量发生变化后的至少一个逻辑信道或者至少一个激活的逻辑信道,比如为所述N个逻辑信道。
以图10为例,网络设备为DRB 2中配置了三个逻辑信道,分别为LCH 1、LCH 2和LCH 3。其中,网络设备为LCH 1配置的LCH-to-Cell restriction,即为LCH 1配置的所允许使用的载波为CC 1和CC 2;网络设备为LCH 2配置的所允许使用的载波为CC 3和CC 4;网络设备为LCH 3配置的所允许使用的载波为CC 5和CC 6。
如果终端设备收到承载于MAC CE的用于指示复制数据传输的状态变更的变更指示信息,假设该变更指示信息指示LCH 3去激活,即激活的逻辑信道由LCH 1、LCH 2和LCH 3变为LCH 1和LCH 2,即M=3且N=2,激活的逻辑信道的数量由多变少,并且假设特定逻辑信道为LCH 1,那么终端设备可以将LCH 3对应的CC 5和CC 6分配给LCH 1,从而使LCH 1所允许使用的载波变为CC 1、CC 2、CC 5和CC 6。
又或者,终端设备可以将LCH 3对应的CC 5和CC 6平均地分配给LCH 1和LCH 2,从而使LCH 1所允许使用的载波变为CC 1、CC 2和CC 5,LCH 1所允许使用的载波变为CC 3、CC 4和CC 6。
又或者,去激活的M-N个逻辑信道所允许使用的载波也可以不使用,即不作为其他逻辑信道所允许使用的载波。例如在图10中,LCH 3去激活后,LCH 3所允许使用的载波CC 5和CC 6不使用,LCH 1所允许使用的载波仍为CC 1和CC 2,LCH 2所允许使用的载波仍为CC 3和CC 4。
图10所示仅仅为示例,还可存在其他分配方式,本申请实施例对此不作任何限定。终端设备可以根据预设的或者网络设备配置的分配规则,对去激活的M-N个逻辑信道所对应的载波进行重新分配,使这些载波分配至其他有待传输数据的逻辑信道上。这样,能够充分利用载波资源,为终端设备提供了更多的传输机会,保证了业务尽快的传输给网络并且满足业务质量(Quality of Service,QoS)。
可选地,910中的所述至少一个逻辑信道的数量是所述承载支持的最大的逻辑信道数量,或者是网络设备为所述终端设备配置的用于复制数据传输的逻辑信道的数量,或者是网络设备为所述终端设备配置的能够用于复制数据传输的逻辑信道的最大数量,或者是所述终端设备支持的最大的逻辑信道数量,或者是所述终端设备支持的用于复制数据传输的承载对应的最大的逻辑信道数量,或者是网络设备为所述终端设备配置的所述承载对应的用于复制数据传输的逻辑信道的数量,或者是所述网络设备为所述终端设备配置的所述承载对应的能够用于复制数据传输的逻辑信道的最大数量。
其中,所述特定逻辑信道可以是一个逻辑信道或多个逻辑信道。所述多个逻辑信道的数量可以是预定义的,或者是终端设备自行确定的,或者是网络设备指示的。
所述特定逻辑信道可以是网络设备配置的所述承载对应的逻辑信道,或者是主小区组MCG下的逻辑信道,或者是辅小区组SCG下的逻辑信道。
例如,所述特定逻辑信道可以是所述N个逻辑信道中的任一逻辑信道,或者是所述承载的复制数据传输功能去激活时可用的逻辑信道,或者是网络设备为所述终端设备配置的主逻辑信道,或者是传输PDCP控制PDU的逻辑信道。
其中,所述主逻辑信道例如可以是传输PDCP控制PDU的逻辑信道,或者是所述承载的复制数据功能去激活时可用的逻辑信道,或者是所述承载的复制数据传输功能初始为去激活时可用的逻辑信道,或者是MCG下的主逻辑信道,或者是SCG下的主逻辑信道,或者是配置的所述承载对应的主逻辑信道。
又例如,所述特定逻辑信道是根据所述至少一个逻辑信道的信道质量、逻辑信道标识和小区组CG 标识中的至少一种确定的。比如,所述特定逻辑信道是所述至少一个逻辑信道中信道质量最好的逻辑信道,或者是所述信道质量高于预设门限的逻辑信道中的任一逻辑信道,或者是逻辑信道标识最大的逻辑信道,或者是信道质量高于所述预设门限的逻辑信道中逻辑信道标识最大的逻辑信道,或者是信道质量高于所述预设门限的逻辑信道中逻辑信道标识最小的逻辑信道。进一步地,还可以通过CG标识,指示该特定逻辑信道是哪个CG下的满足上述条件的逻辑信道。
所述特定逻辑信道可以是一个逻辑信道,或者是多个逻辑信道。
可选地,如图9所示,在910之前,该方法还包括920和930。
在920中,网络设备向终端设备发送第二指示信息。
在920中,终端设备接收网络设备发送的所述第二指示信息。
其中,所述第二指示信息用于指示终端设备在一个承载对应的激活的逻辑信道的数量发生变化时,确定所述承载对应的至少一个逻辑信道所允许使用的载波。
这时,在910中,所述终端设备根据所述第二指示信息,在一个承载下激活的逻辑信道的数量发生变化时,确定所述至少一个逻辑信道所允许使用的载波。
上述的分配规则可以是预配置的例如协议中约定的,或者,也可以通过所述第二指示信息来指示上述的分配规则。第二指示信息指示终端设备将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,作为所述N个逻辑信道中特定逻辑信道所允许使用的载波中的至少部分载波;或者指示终端设备将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,平均地分配给所述N个逻辑信道中的各个逻辑信道,以作为所述N个逻辑信道中的各个逻辑信道所允许使用的载波;或者指示终端设备将去激活的M-N个逻辑信道所允许使用的载波中的至少部分载波,平均地分配给K个逻辑信道中的各个逻辑信道,以作为所述K个逻辑信道中的各个逻辑信道所允许使用的载波,其中K<N。
所述第二指示信息例如还可以指示对所述承载对应的至少一个逻辑信道所允许使用的载波进行修改和/或重新确定。终端设备接收到第二指示信息后,修改所述至少一个逻辑信道所允许使用的载波。
可选地,在910之前,网络设备可以向终端设备发送RRC消息,所述RRC消息中包括所述至少一个逻辑信道所允许使用的载波的信息。相应地,所述终端设备接收该RRC消息。
举例来说,网络设备可以通过RRC消息,为终端设备的DRB 1配置对应的逻辑信道标识、小区组标识、去激活时可用的逻辑信道(也称为主腿(primary leg))等。同时,所述RRC消息可以指示复制数据传输的初始状态,和/或,该初始状态下的该承载对应的每个逻辑信道所允许使用的载波的列表。网络设备可以按照一个承载所支持的最大数量的逻辑信道,配置各逻辑信道所允许使用的载波;也可以针对一个CG的CA下的最大数量的逻辑信道,配置各逻辑信道所允许使用的载波。
例如,网络设备可以配置DRB 2为CA下的复制数据传输的承载,该承载对应的逻辑信道包括LCH 1、LCH 2和LCH 3。其中,LCH 1对应MCG且所允许使用的载波为CC 1和CC 2,LCH 2对应MCG且所允许使用的载波为CC 3和CC 4,LCH 3对应MCG且所允许使用的载波为CC 5和CC 6。
又例如,网络设备可以配置DRB 1为CA和DC下的复制数据传输的承载,该承载对应的LCH 1对应MCG,LCH 2对应MCG,LCH 3对应MCG,LCH 4对应SCG。网络设备对DRB 1对应的MCG配置了CA下的复制数据传输功能,且该MCG的CA下的复制数据传输所支持的最大逻辑信道的数量为3,则按照3个逻辑信道进行配置,比如配置LCH 1所允许用的载波为CC 1和CC 2,LCH 2所允许用的载波为CC 3和CC 4,LCH 3所允许用的载波为CC 5和CC 6。SCG的LCH 4所允许使用的载波为CC 7和CC 8。
终端设备根据该RRC消息,进行该承载的复制数据传输的配置。之后,如果终端设备收到承载于MAC CE的用于指示复制数据传输的状态变更的变更指示信息,或者终端设备根据变更条件确定复制数据传输的状态变更,例如去激活了某个逻辑信道,则终端设备可以将为该逻辑信道配置的所允许使用载波,分配至其他逻辑信道例如primary leg或其他任意一个激活的逻辑信道上,例如图10所示。
应理解,如果终端设备收到承载于MAC CE的变更指示信息,或者终端设备根据变更条件确定复制数据传输的状态变更,且激活的逻辑信道的数量由少变多,终端设备也可以按照预设规则重新确定新增加的激活的逻辑信道所允许使用的载波,例如将特定的逻辑信道所允许使用的载波中的一个或几个分配给所述新增的逻辑信道,又例如平均地将其他所有逻辑信道所允许使用的载波中的部分,分配给所述新增的逻辑信道。这里不做限定。
可选地,所述终端设备的一个承载的复制数据传输功能去激活时可用的逻辑信道的数据,能够在任一载波上传输,即为其配置的LCH-to-Cell restriction失效或者没有为其配置LCH-to-Cell restriction。例如,假设上述DRB 1的复制数据传输功能去激活时可用的逻辑信道为LCH 1,则LCH 1上的数据可以在任一载波上传输。
或者,可选地,所述终端设备的一个承载的复制数据传输功能去激活时可用的逻辑信道所允许使用 的载波,可以根据网络设备为该承载配置的所允许使用的载波列表确定。例如,假设上述DRB 1的复制数据传输功能去激活时可用的逻辑信道为LCH 1,则LCH 1所允许使用的载波为网络设备通过RRC信令为其配置的载波。
可选地,所述方法还包括:所述终端设备接收上行授权信息;所述终端设备使用所述上行授权信息指示的上行资源,发送所述承载对应的目标逻辑信道的数据,所述目标逻辑信道所允许使用的载波与所述上行资源所在的载波匹配。
例如,如果目标逻辑信道所允许使用的载波为CC1和CC2,而该上行资源所在的载波为CC1,则该目标逻辑信道的数据能够在该上行资源上发送。
进一步地,可选地,若所述上行资源所在的载波上的信道质量满足预设条件,所述终端设备使用所述上行资源,发送所述目标逻辑信道的数据。
也就是说,所述终端设备在判断该目标逻辑信道的数据能够在该上行资源上发送时,还需要判断该上行资源所在的载波上的信道质量是否满足预设条件,例如RSRP大于RSRP阈值、或者RSRQ大于RSRQ阈值、或者SINR小于SINR阈值时,终端设备才使用所述上行资源,发送该目标逻辑信道的数据。
