Description

基于载波聚合的反馈方法和设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及基于载波聚合的反馈方法和设备。
背景技术
在载波聚合(Carrier Aggregation,CA)场景下,发送端可以采用双连接(Dual Connectivity,DC)的分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)复制(Duplication)功能来传输复制PDCP协议数据单元(Protocol Data Unit,PDU)。具体地,从PDCH层进行数据复制,相同的PDCP PDU分别映射到不同的无线链路层控制协议(Radio Link Control,RLC)实体(Entity),RLC Entity把这些相同的数据放到不同的逻辑信道。介质访问控制(Medium Access Control,MAC)Entity通过调度,把复制数据调度到不同的物理载波上,以获得频率分集增益,提高数据传输可靠性。
接收端将会接收到不同物理载波上的复制数据,在某种情况下,一个载波信道情况好终端设备解调数据成功,另一个载波信道情况差终端解调失败。根据现有相关技术,接收端分别进行混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)反馈,传输端接收到否定确认(Negative Acknowledgment, NACK)信息时,会对数据进行重传,相当于对冗余数据进行重传,导致系统资源浪费。

在本申请实施例中,终端设备可以包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment,UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等,该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进行通信,例如,终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例中,网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站,所述基站可以包括各种形式的宏基站,微基站,中继站,接入点等。在采用不同的无线接入技术的系统中,具有基站功能的设备的名称可能会有所不同。例如在LTE网络中,称为演进的节点B(Evolved NodeB,eNB或eNodeB),在第三代(3rd Generation,3G)网络中,称为节点B(Node B)等等。
图1示出了根据本申请实施例的基于载波聚合的反馈方法。如图1所示,方法100包括:
S110,如果终端设备确定M个成员载波上承载的数据相同,所述终端设备根据每个成员载波上承载的数据的解调状态,确定反馈信息,所述反馈信息用于网络设备在根据所述反馈信息确定所述每个成员载波上承载的数据中存在被成功解调的数据时,不重传所述数据,M大于或等于2的正整数;
S120,所述终端设备确定所述M个成员载波中用于发送所述反馈信息的N个目标成员载波,N为大于或等于1的正整数;
S130,所述终端设备在所述N个目标成员载波中的每个目标成员载波上向网络设备发送所述反馈信息。
根据本申请实施例的基于载波聚合的反馈方法,终端设备在确定多个成员载波上承载的数据相同时,根据每个成员载波上承载的数据的解调状态,确定反馈信息,使得网络设备在根据该反馈信息确定每个成员载波上承载的数据中存在被成功解调的数据时,不进行数据的重传。由此,能够避免对冗余数据的重传,提高系统资源的利用率。
在本申请实施例中,成员载波指的是进行载波聚合的载波。
需要说明的是,M个成员载波上承载的数据相同可以理解为M个成员载波上承载了完全相同的传输块(Transport Block ,TB);或者M个成员载波上承载的数据相同也可以理解为M个成员载波上承载的TB不完全相同,但M个成员载波上承载的TB中包含的分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)协议数据单元(Protocol Data Unit,PDU)相同。
在本申请实施例中,可选地,网络设备和终端设备事先约定选取用于传输反馈信息的目标成员载波的规则,终端设备根据事先约定的规则选择用于传输反馈信息的目标成员载波。或者,网络设备向终端设备发送第一配置信息,第一配置信息中包括第一信息,第一信息用于指示N个目标成员载波,则终端设备根据第一信息确定用于传输反馈信息的N个目标成员载波。之后,终端设备只在确定的N个目标成员载波上向网络设备发送反馈信息,在其他成员载波上不向网络设备发送反馈信息。例如,第一信息指示终端设备在1个目标成员载波上向网络设备发送反馈信息,此时终端设备仅在网络设备配置的这1个目标成员载波上向网络设备发送反馈信息。
并且,网络设备和终端设备可以事先约定,在网络设备没有进行特定配置的情况下,如果终端设备确定M个成员载波上承载的数据中存在解调成功的数据,终端设备确定反馈信息为包括1个比特的ACK信息,如果终端设备确定M个成员载波上承载的数据均解调失败,终端设备确定反馈信息为包括1和比特的NACK信息。也就是说,如果终端设备确定需要在M个成员载波中每个成员载波上向网络设备发送反馈信息,并且每个成员载波上承载的数据中存在解调成功的数据,终端设备在每个成员载波上向网络设备发送ACK信息(即使在承载的数据解调失败的成员载波上,终端设备向网络设备发送的是ACK信息而不是现有技术中的NACK信息)。由此,网络设备确定不需要对数据进行重传,避免冗余数据的重传,提高系统资源的利用率。
举例来说,如图2所示出的,载波1和载波2上承载的数据相同,并且终端设备确定需要在载波1上向终端设备发送反馈信息。则终端设备在时隙n接收到载波1和载波2上承载的数据之后,对载波1和载波2上的数据进行独立解调。假设载波1上承载的数据解调成功,而载波2上承载的数据解调失败,终端设备在时隙n+m上在载波1上向网络设备发送ACK信息。网络设备在载波1上接收到ACK信息之后,在时隙n+k上在载波1和载波2上传输新数据,其中,m,k为大于后等于0的正整数。
或者,如图3所示出的,载波1和载波2上承载的数据相同,并且终端设备确定需要在载波1和载波2上向终端设备发送反馈信息。则终端设备在时隙n接收到载波1和载波2上承载的数据之后,对载波1和载波2上的数据进行独立解调。假设载波1上承载的数据解调成功,而载波2上承载的数据解调失败,则终端设备在时隙n+m在载波1和载波2上向网络设备均发生ACK信息。网络设备在载波1和载波2上接收到ACK信息之后,在时隙n+k上在载波1和载波2上传输新数据,其中,m,k为大于后等于0的正整数。
在上述实施例中,可选地,在第一配置信息中还包括第二信息,第二信息用于指示反馈信息包括的比特的数量。终端设备根据第二信息和每个成员载波上承载的数据的解调状态,确定反馈信息。
具体地,在一些实施例中,如果第一信息指示反馈信息包括的比特的数量小于M,第一信息还用于指示每个比特承载的信息与成员载波上承载的数据的解调状态的对应关系。
举例来说,假设M的取值为8,第一信息指示反馈信息包括的比特的数量为4,则第一信息指示每个比特指示2个成员载波上承载的数据的解调状态。假设数据解调成功对应比特的取值为1,解调失败对应比特的取值为0,与一个比特对应的两个成员载波中只要有一个成员载波上承载的数据解调成功,这个比特的取值为1。则如果成员载波1上承载的数据解调成功,其他成员载波上承载的数据均解调失败,则反馈信息中比特的取值为1000。当网络设备接收到这个反馈信息时,根据比特的取值确定有一个成员载波上承载的数据被成功解调,则网络设备不进行重传,直接进行新数据的传输。
或者,假设M个取值为8,第一信息指示反馈信息包括的比特的数量为8,则每个比特承载的信息对应一个成员载波上承载的数据的解调状态。假设成员载波1和成员载波5上承载的数据被成功解调,则反馈信息中比特的取值为10001000。当网络设备接收到这个反馈信息时,根据比特的取值确定成员载波1和成员载波5上承载的数据被成功解调,不需要进行重传,网络设备直接进行新数据的传输。
在上述实施例中,可选地,终端设备根据预设规则确定每个成员载波对应的用于承载反馈信息的时频资源。或者网络设备可以对终端设备发送反馈信息的时频资源进行配置。例如,第一配置信息中包括第三信息,第三信息用于指示每个目标成员载波对应的用于承载反馈信息的时频资源。进而终端设备在第三信息指示的时频资源上向网络设备发送反馈信息。
进一步地,在第一配置信息中还包括第四信息和混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)传输相关信息,第四信息用于指示M个成员载波上承载的数据相同,终端设备根据第四信息确定所述M个成员载波上承载的数据相同。其中HARQ传输相关信息包括每个成员载波上使用的HARQ进程的标识(Identification,ID)、新数据指示等信息。
可以理解的是,在第一配置信息中可以不包括第四信息,这时终端设备可以根据HARQ进程的ID判断M个成员载波上承载的数据是否相同。例如,可以预先设定某些HARQ进程用于传输相同的数据,当终端设备确定M个成员载波中每个成员载波使用的HARQ进程均在预先设定的这些HARQ进程中时,终端设备确定M个成员载波上承载的数据相同。
在本申请实施例中,可选地,网络设备通过高层信令(例如,无线资源控制(Radio Resource Control,简称为“RRC”)信令)半静态的配置某些时隙(Slot)或者小时隙(mini-slot),在这些配置的时隙或小时隙中,网络设备在所述M个成员载波上传输相同的数据。由此,当终端设备在配置的这些时隙或者小时隙内接收到网络设备在所述M个成员载波上传输的数据时,终端设备确定这M个成员载波上承载的数据相同。进而,网络设备不需要通过额外的下行控制信息(Downlink Control Information,DCI)动态指示多个成员载波上承载的数据是否相同。由此,能够节省信令开销。
在上述所有实施例中,终端设备可以采用与现有技术中的反馈信息相同的调制编码方式对本申请实施例中的反馈信息进行调制编码。终端设备还可以采用更鲁棒性的调制编码方式对本申请实施例中的反馈信息进行调制编码,以与现有技术中包括1比特的反馈信息区别开。由此当网络设备接收到反馈信息时能够准确的根据该反馈信息确定在其他没有收到反馈信息的成员载波上的操作,例如重传或者传输新数据。
以上结合图1至图3从终端设备侧详细描述根据本申请实施例的基于载波聚合的反馈方法,下面将结合图4从网络设备侧详细描述根据本申请实施例的基于载波聚合的反馈方法。应理解,网络设备侧描述的网络设备与终端设备的交互与终端设备侧的描述相同,为避免重复,适当省略相关描述。

换句话说,如果网络设备在第一成员载波上接收到反馈信息之前,在另一成员载波上接收到反馈信息,并且在另一成员载波上接收到的反馈信息指示该另一成员载波上承载的数据没有被成功解调,网络设备在该另一成员载波上进行HARQ重传。在网络设备在该另一成员载波上进行HARQ重传的过程中,网络设备在第一成员载波上接收到了反馈信息,且反馈信息指示该第一成员载波上承载的数据解调成功,则网络设备通知在该另一成员载波上的HARQ重传。之后网络设备在M个成员载波上进行新数据的传输。
在本申请实施例中,可选地,S230具体为:如果所述M个成员载波上承载的数据两两不同,且所述反馈信息指示所述第一成员载波上承载的数据解调成功,所述网络设备在所述第一成员载波上向所述终端设备传输新数据;或,如果所述M个成员载波上承载的数据两两不同,且所述反馈信息指示所述第一成员载波上承载的数据解调失败,所述网络设备在所述第一成员载波上重传所述数据。

在本申请实施例中,可选地,所述方法200还包括:所述网络设备向所述终端设备发送第一配置信息,所述第一配置信息包括下列信息中的至少一种:第一信息、第二信息、第三信息、第四配置信息和混合自动重传请求HARQ传输相关信息,其中,所述第一信息用于指示所述第一成员载波,所述第二信息用于指示所述反馈信息包括的比特的数量,所述第三信息用于指示所述第一成员载波对应的用于承载所述反馈信息的时频资源,所述第四配置信息用于指示所述M个成员载波上承载的数据相同。
