Abstract

一种反馈信息的传输装置及方法。用户设备接收或生成边链路反馈信息并向网络设备发送该边链路反馈信息,从而提供了一种边链路传输的反馈机制,能够提升边链路的数据传输的可靠性。

Description

反馈信息的传输装置及方法 技术领域
本发明涉及通信领域,尤其涉及一种反馈信息的传输装置及方法。
背景技术
汽车通信业务,被称为V2X业务。V2X业务可以包括多种类型,例如:车对车(Vehicle-to-Vehicle,V2V)通信业务,车对基础设施(Vehicle-to-Infrastructure,V2I)通信业务,车对人(Vehicle-to-Pedestrian,V2P)通信业务等。
在现有的V2X通信中,作为用户设备(User Equipment,UE)的车和车之间在边链路(sidelink)上通过PC5接口进行数据的传输,对于边链路数据信道PSSCH,由对应的物理边链路控制信道PSCCH指示其具体使用的资源;而车和网络设备(Network Equipment,NE)之间可以通过上行、下行链路并通过Uu接口进行数据的传输。在R-15以及之前版本的基于LTE技术的V2X通信(LTE-V2X)中,在边链路上的业务都是广播发送的,接收的UE不需要对发送数据包进行反馈。在边链路上,发送数据的UE称为源UE,接收数据的UE称为目的UE。
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现,在NR-V2X(新无线汽车通信)中,由于需要同时支持在边链路上的单播(unicast)、组播(groupcast)以及广播(broadcast)业务,并同时对数据发送的可靠性较之LTE-V2X有更高的要求,对于单播和组播业务,可以通过支持反馈来提升数据传输的可靠性。如果此时源UE在网络设备的小区覆盖内,则网络设备需要获得此次边链路传输的反馈信息,如果发现反馈为没有确认(NACK),则网络设备可以重新调度资源使得源UE对目的UE进行重传。因此,在NR-V2X中,对于源UE在小区覆盖内的场景,需要建立相应的反馈机制

实施例1
本发明实施例提供一种反馈信息的传输方法,应用于第一用户设备侧或第二用户设备侧。图2是本发明实施例1的反馈信息的传输方法的一示意图。如图2所示,该方法包括:
步骤201:第一用户设备接收边链路反馈信息,或者,第二用户设备生成边链路反馈信息;以及
步骤202:向网络设备发送该边链路反馈信息,
该边链路反馈信息为该第一用户设备向该第二用户设备的边链路传输的反馈信息。
这样,用户设备接收或生成边链路反馈信息并向网络设备发送该边链路反馈信 息,从而提供了一种边链路传输的反馈机制,能够提升边链路的数据传输的可靠性。
在本实施例中,第一用户设备和第二用户设备之间可以进行边链路传输,第一用户设备是源UE,第二用户设备是目的UE,那么,该边链路传输是第一用户设备向第二用户设备的边链路传输。
以下,对该方法应用于第二用户设备侧和第一用户设备侧分别进行说明。
首先,针对该方法应用于第二用户设备侧(目的UE侧)的情况进行说明。
例如,该方法可以用于第二用户设备处于与第一用户设备相同的小区覆盖之下的场景。
图3是本发明实施例1的反馈信息的传输方法的另一示意图,该方法应用于第二用户设备侧。如图3所示,该方法包括:
步骤301:从第一用户设备或网络设备接收进行反馈信息发送的相关指示信息;
步骤302:生成该第一用户设备向该第二用户设备的边链路传输的反馈信息;
步骤303:根据该进行反馈信息发送的相关指示信息,向网络设备发送该第一用户设备向该第二用户设备的边链路传输的反馈信息。
在本实施例中,该进行反馈信息发送的相关指示信息可以通过控制信令发送。
在本实施例中,在从第一用户设备接收进行反馈信息发送的相关指示信息的情况下,该控制信令由物理边链路控制信道(Physical Sidelink Shared Channel,PSSCH)承载。
例如,该控制信令包含在边链路控制信息(Sidelink Control Information,SCI)中。
在本实施例中,在从网络设备接收进行反馈信息发送的相关指示信息的情况下,该控制信令由物理下行控制信道(Physical Downlink Control Channel,PDCCH)承载。
例如,该控制信令包含在下行控制信息(Downlink Control Information,DCI)中。
针对第二用户设备从第一用户设备接收进行反馈信息发送的相关指示信息的情况,图4是本发明实施例1的反馈信息的传输方法的又一示意图,其应用于第一用户设备侧。如图4所示,该方法包括:
步骤401:从网络设备接收进行反馈信息发送的相关指示信息;
步骤402:将该进行反馈信息发送的相关指示信息转发给第二用户设备,
其中,该第一用户设备向该第二用户设备进行边链路传输。
在步骤401中,可以通过物理下行控制信道(PDCCH)接收该进行反馈信息发送的相关指示信息。
在步骤402中,可以通过物理边链路控制信道(PSCCH)向该第二用户设备发送该进行反馈信息发送的相关指示信息。
在步骤301中,在第二用户设备从网络设备接收进行反馈信息发送的相关指示信息的情况下,该控制信令由PDCCH承载,该PDCCH中与调度相关的域被置为无效,与进行反馈相关的域被置为有效。例如,DCI中与调度相关的域置为全“0”或全“1”或预先约定好的一个值,以指示当前域无效。其中,与调度相关的域包括但不限于时域调度域、频域调度域、调制编码指示域、MCS指示域,指示无效的域也可以包括载波指示(carrier indicator)域。
在该情况下,网络设备还向作为边链路的源UE的第一用户设备发送用于边链路调度的PDCCH,该PDCCH中与调度相关的域被置为有效,与反馈相关的域被置为无效。例如,DCI指中与反馈相关的域置为全“0”或全“1”或预先约定好的一个值,指示当前域无效,UE可以忽略。其中,反馈相关的域可以包括目的UE进行反馈的时间以及进行反馈所使用的上行PUCCH资源等。
例如,可以通过以下的两种具体方法实现:
方法一:
i.网络设备发给源UE(第一用户设备)的DCI用源UE的RNTI加扰,且DCI中包含目的UE(第二用户设备)的ID;发给目的UE的DCI用目的UE的RNTI加扰,且DCI中包括源UE的ID;或者,发送给源的和目的UE的DCI都用用一个pair/link RNTI加扰,则不需要在双方的DCI中包括ID;
ii.在步骤i的基础上,在DCI中包含1bit指示当前收到DCI的UE为源UE还是目的UE,对于DCI中包含ID的方法,则此1bit也指示了ID field是对应源UE还是目的UE,具体的,如果是源UE,则ID field对应目的UE;反之,则ID field对应源UE;对于pair/link RNTI方法,DCI中不需要包括任何UE ID。那么,两个UE通过解码各自的DCI,能够知道二者谁是源UE,谁是目的UE。对于源UE,此DCI用作数据调度,反馈相关的域无效;对于目的UE,此DCI用于指示反馈信息,调度相关的域无效。
方法二:
使用一个pair或link ID加扰,向源UE和目的UE发送同一个PDCCH,其中的DCI中分别包含源和目的UE的ID,并包含区分指示比特,同时需要包含调度的域和HARQ反馈相关域,这样能够节省一条PDCCH信令资源。
在上述方法一和方法二中,边链路控制信道PSCCH中的SCI指示信息中不需要包含指示目的UE进行反馈相关的域。
在本实施例中,该进行反馈信息发送的相关指示信息可以包括发送该边链路传输的反馈信息的时间和/或发送该边链路传输的反馈信息所使用的资源,以便第二用户设备在该时间和/或该资源上发送该反馈信息。
在本实施例中,发送该边链路传输的反馈信息的时间也可以不包含在该进行反馈信息发送的相关指示信息中的,例如,该时间是预定义或预配置的。
在本实施例中,例如,该发送该边链路传输的反馈信息的时间是:
从第一用户设备或网络设备接收到携带该进行反馈信息发送的相关指示信息的PDCCH的最后一个符号或该物理下行控制信道所在时隙的最后一个符号之后的第一时间,或者,携带从第一用户设备接收到边链路传输的数据的PSSCH的最后一个符号或该物理边链路共享信道所在时隙的最后一个符号之后的第二时间。
以上针对该方法应用于第二用户设备侧(目的UE侧)的情况进行了说明。接着,针对该方法应用于第一用户设备侧(源UE侧)的情况进行说明。
例如,下述的图5和图6所示的方法可以用于第二用户设备不处于第一用户设备所在的小区覆盖之下的场景,也可以用于第二用户设备处于第一用户设备所在的小区覆盖之下的场景。
图5是本发明实施例1的反馈信息的传输方法的又一示意图,该方法应用于第一用户设备侧。如图5所示,该方法包括:
步骤501:从网络设备接收进行反馈信息发送的相关指示信息;
步骤502:从第二用户设备接收该第一用户设备向该第二用户设备的边链路传输的反馈信息;以及
步骤503:根据该进行反馈信息发送的相关指示信息,向网络设备发送该第一用户设备向该第二用户设备的边链路传输的反馈信息。
在步骤501中,通过物理下行控制信道(PDCCH)接收该进行反馈信息发送的相关指示信息。

由上述实施例可知,用户设备接收或生成边链路反馈信息并向网络设备发送该边链路反馈信息,从而提供了一种边链路传输的反馈机制,能够提升边链路的数据传输的可靠性。
实施例2
本发明实施例提供了一种反馈信息的传输方法,该方法应用于用户设备侧。图7是本发明实施例2的反馈信息的传输方法的一示意图。如图7所示,该方法包括:
步骤701:向网络设备发送该用户设备向另一用户设备的边链路传输的反馈信息以及该用户设备与该网络设备之间的下行传输的反馈信息。
在本实施例中,该用户设备和该另一用户设备之间可以进行边链路传输,该用户设备是源UE,该另一用户设备是目的UE,那么,该边链路传输是该用户设备向该另一用户设备的边链路传输。
在本实施例中,该边链路传输的反馈信息和该下行传输的反馈信息可以在相同的或不同的资源上发送。
例如,该边链路传输的反馈信息通过调度边链路传输的第一物理下行控制信道中指示的第一资源发送,该下行传输的反馈信息通过调度下行传输的第二物理下行控制信道中指示的第二资源发送,该第一资源和该第二资源可以相同或不同。
例如,发送该反馈信息使用的PUCCH资源可以是调度DL的PDCCH中携带的DCI中指示的资源,也可以是调度边链路传输的PDCCH中携带的DCI中指示的资源,或者,取决于两者指示的PUCCH资源是否相同,如果相同,则在相同的PUCCH资源中对DL和边链路传输进行反馈;如果不同,则分别在各自调度DCI中指示的PUCCH资源中进行反馈。同时,调度边链路传输的DCI中需要增加DAI域,用于进行反馈。
首先对该边链路传输的反馈信息和该下行传输的反馈信息在相同的资源上发送进行说明。
在本实施例中,在步骤701中,可以是向该网络设备发送该边链路传输的反馈信息和该下行传输的反馈信息合并后的反馈信息。
例如,该合并后的反馈信息包括:
先按照该下行传输的载波和边链路传输的载波的预定顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的反馈码字,该预定顺序是该下行传输的载波在前且该边链路传输的载波在后,或者,该边链路传输的载波在前且该下行传输的载波在后,或者,
先按照该下行传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第一反馈码字和先按照该边链路传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第二反馈码字再次级联后形成的反馈码字,其中,该第一反馈码字在该第二反馈码字的前面,或者,该第一反馈码字在该第二反馈码字的后面。
图8是本发明实施例2的下行传输的载波和边链路传输的各个载波所对应的各个发送时机的反馈结果的一示意图。如图8所示,下行传输配置了载波0和载波1,边链路传输配置了载波0和载波1,对应于这些载波的发送时机0、发送时机1和发送时机2的部分发送时机具有反馈结果,可以表示为“00”、“01”、“10”或“11”,假设支持两个TB的传输,则00代表对应时机对应载波上,两个TB都没有正确解码;01代表TB0没有正确解码,TB1正确解码;以此类推。
例如,在对边链路传输的反馈信息和边链路的反馈信息进行合并时,先按照该下行传输的载波在前且该边链路传输的载波在后的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的反馈码字作为合并的反馈信息,例如,对于图8 所示的反馈结果,按照该方式排序并级联后形成的反馈码字为“11101101111110”;
又例如,在对边链路传输的反馈信息和边链路的反馈信息进行合并时,先按照该边链路传输的载波在前且该下行传输的载波在后的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的反馈码字作为合并的反馈信息,例如,对于图8所示的反馈结果,按照该方式排序并级联后形成的反馈码字为“10111111011011”;
又例如,在对边链路传输的反馈信息和边链路的反馈信息进行合并时,先按照该下行传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第一反馈码字和先按照该边链路传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第二反馈码字再次级联后形成的反馈码字作为合并的反馈信息,其中,该第一反馈码字在该第二反馈码字的前面,例如,对于图8所示的反馈结果,按照该方式排序并级联后形成的反馈码字为“11011110111110”;
又例如,在对边链路传输的反馈信息和边链路的反馈信息进行合并时,先按照该下行传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第一反馈码字和先按照该边链路传输的载波的顺序,再按照各个发送时机的顺序,将反馈结果进行排序并级联后形成的第二反馈码字再次级联后形成的反馈码字作为合并的反馈信息,其中,该第一反馈码字在该第二反馈码字的后面,例如,对于图8所示的反馈结果,按照该方式排序并级联后形成的反馈码字为“10111110110111”。
在本实施例中,该边链路传输的反馈信息和该下行传输的反馈信息也可以在不同的资源上发送。
例如,该边链路传输的反馈信息和该下行传输的反馈信息在不同的PUCCH资源中发送。
也可以是,适用于指示的发送该边链路传输的反馈信息和该下行传输的反馈信息的PUCCH资源不同的情况下。例如,下行传输的反馈信息在调度下行传输的PDCCH中携带指示的资源中发送,边链路传输的反馈在调度边链路传输的PDCCH中携带指示的资源中发送。
由上述实施例可知,用户设备向网络设备发送边链路反馈信息,从而提供了一种边链路传输的反馈机制,能够提升边链路的数据传输的可靠性。另外,提供了一种同时存在边链路传输的反馈信息和下行传输的反馈信息的情况下的反馈机制。
实施例3
本发明实施例还提供一种反馈信息的传输方法,该方法应用于第一用户设备(源UE)侧。
图9是本发明实施例3的反馈信息的传输方法的一示意图。如图9所示,该方法包括:
步骤901:从网络设备接收进行反馈信息发送的相关指示信息;
步骤902:从属于一组的至少两个第二用户设备分别接收该第一用户设备向该至少两个第二用户设备的边链路传输的反馈信息;
步骤903:根据该进行反馈信息发送的相关指示信息以及该第一用户设备向该至少两个第二用户设备的边链路传输的反馈信息,向网络设备发送边链路传输的反馈信息。
在本实施例中,第一用户设备(源UE)和至少两个第二用户设备(目的UE)构成了一个组,第一用户设备(源UE)向构成为一个组的至少两个用户设备(目的UE)以组播的方式进行边链路传输。
在步骤901中,可以通过物理下行控制信道(PDCCH)接收该进行反馈信息发送的相关指示信息。
在本实施例中,该进行反馈信息发送的相关指示信息可以包括发送该边链路传输的反馈信息的时间和/或发送该边链路传输的反馈信息所使用的资源。
例如,该发送该边链路传输的反馈信息的时间是:
从网络设备接收到携带该进行反馈信息发送的相关指示信息的PDCCH的最后一个符号或该PDCCH所在时隙的最后一个符号之后的第三时间;或者,携带向该至少两个第二用户设备发送边链路传输的数据的PSSCH的最后一个符号或该PSSCH所在时隙的最后一个符号之后的第四时间。
在本实施例中,向网络设备发送的该边链路传输的反馈信息可以包括:从该至少两个第二用户设备分别接收的该第一用户设备向该至少两个第二用户设备的边链路传输的至少两个反馈码字级联后的反馈码字。例如,第一用户设备和至少两个第二用户设备构成为一组,各个用户设备具有序号,例如,表示其序号的ID分别为0,1,……,n-1,那么这一组共有n个用户设备。可以按照各个第二用户设备的ID的顺序,对各个第二用户设备的反馈码字进行级联。其中,可以是按照ID由小到大进行排序,也可以是按照ID由大到小进行排序。
由于组播是一对多的调度,是由同一条PDCCH调度多个UE的一次传输,因此,对于组内的所有第二用户设备(目的UE),在发送时机内是否传输、以及传输使用的子载波索引均相同,所以对于组内的目的UE来说,每一次反馈时间内需要反馈的比特数是相等的。因此,对于网络设备来说,能够清楚源UE反馈的反馈码字中的哪些比特对应于哪个目的UE的反馈信息,不会产生混淆。
在本实施例中,或者,向网络设备发送的该边链路传输的反馈信息也可以包括:先按照该第一用户设备向该至少两个第二用户设备的边链路传输的载波的预定顺序,再按照各个发送时机的顺序,将反馈结果级联后形成的反馈码字,该预定顺序是按照该至少两个第二用户设备的序号进行的排序。其中,可以是按照序号由小到大进行排序,也可以是按照序号由大到小进行排序。
图10是本发明实施例3的第一用户设备向至少两个第二用户设备的边链路传输配置的各个载波所对应的各个发送时机的反馈结果的一示意图。如图10所示,属于一组的三个第二用户设备UE0,UE1和UE2,第一用户设备向属于一组的三个第二用户设备的边链路传输均配置了载波0和载波1,对应于这些载波的发送时机0、发送时机1和发送时机2的部分发送时机具有反馈结果,表示为“00”、“01”、“10”或“11”。
例如,对于图10所示的反馈结果,先按照该第一用户设备向该至少两个第二用户设备的边链路传输的载波的预定顺序(第二用户设备序号由小到大),再按照各个发送时机的顺序,将反馈结果级联后形成的反馈码字为“111011011101111111100001”。
在步骤903中,根据该进行反馈信息发送的相关指示信息以及该第一用户设备向该至少两个第二用户设备的边链路传输的反馈信息,向网络设备发送边链路传输的反馈信息。
图11是本发明实施例3的步骤903的实现方法的一示意图,如图11所示,该方法包括:
步骤1101:对该第一用户设备向该至少两个第二用户设备的边链路传输的反馈信息进行综合处理,获得该第一用户设备向该至少两个第二用户设备的边链路传输的整体反馈信息;
步骤1102:将该整体反馈信息发送给该网络设备。
例如,该综合处理是逻辑“与”计算过程。
例如,属于一组的4个第二用户设备(目的UE)的反馈结果为{1,1,1,1},则第一用户设备(源UE)向网络设备反馈{1};如果组内该4个第二用户设备的反馈结果为{1,0,1,1},则第一用户设备向网络设备反馈{0}。例如,1代表正确,0代表错误。
在本实施例中,该方法还可以包括:
步骤904:向该网络设备发送该第一用户设备与该网络设备之间的下行传输的反馈信息。
在本实施例中,该边链路传输的反馈信息和该下行传输的反馈信息在相同的或不同的资源中发送。
在本实施例中,步骤904为可选步骤。
在本实施例中,步骤904和步骤903可以分别执行,对其执行的顺序不进行限制,另外,步骤904和步骤903也可以合并进行,例如,向该网络设备发送该边链路传输的反馈信息和该下行传输的反馈信息合并后的反馈信息。
在本实施例中,当需要发送下行传输的反馈信息和边链路传输的反馈信息时,其具体的发送方法可以参见实施例2中的记载,此处不再赘述。

也就是说,对第一用户设备(源UE)向属于一组的至少两个第二用户设备的边链路传输的反馈信息的综合处理也可以不由第一用户设备执行,而由网络设备执行。该网络设备进行综合处理的方法可以参见实施例3中的记载,此处不再赘述。
由上述实施例可知,属于一组的目的UE通过源UE向网络设备发送边链路反馈信息,从而提供了一种组播形式的边链路传输的反馈机制,能够提升边链路的数据传输的可靠性。
