Description

一种控制信息传输方法及装置
本申请要求于2020年02月14日提交国家知识产权局、申请号为PCT/CN2020/075394、申请名称为“一种控制信息传输方法及装置”的PCT专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种控制信息传输方法及装置。
背景技术
码分复用(code division multiple access,码分复用A)是一种以扩频通信为基础的载波调制和多址连接技术,不同用户设备传输的数据所用的信号不是依据频率不同或时隙不同来区分,而是用各自不同的扩频序列来区分的。码分复用A技术在无线通信系统中被广泛应用,例如,第3代移动通信系统W码分复用A(Wideband Code Division Multiple Access宽带码分多址),长期演进(long term evolution,LTE)为代表的4G系统等。
在无线通信系统中,码分复用A技术即可以用来传输数据也可以用来传输控制信令。在传输控制信令时,码分复用A技术具有很多优点,例如,提高控制信息传输的可靠性、增加控制信息传输时的覆盖、以及实现多用户对同一个时频资源的复用等。在实现多用户对同一个时频资源的复用时,通常使用具有良好相关特性的序列,来实现序列之间的正交。
现有技术中,不同用户设备(user equipment,UE)可以使用不同的序列在相同的时频资源上向基站发送反馈信息,每个UE使用的序列和时频资源都是基站通过信令来配置的,该序列可以通过序列参数(例如,基序列和循环移位值)来配置。如图1所示,基站可以通过信令分别为三个用户设备配置的序列为序列1、序列2和序列3,从而这三个用户设备可以在相同的时频资源上分别使用序列1、序列2和序列3向基站发送反馈信息。但是,当基站由于某些原因无法为UE配置序列参数、或者不存在基站的场景下,如何有效地为不同UE分配序列参数和时频资源,仍是一个亟待解决的问题。
发明内容

本申请实施例中,能够与基站进行数据通信的都可以看作终端设备。
如上介绍的各种终端设备,如果位于车辆上(例如放置在车辆内或安装在车辆内),都可以认为是车载终端设备,车载终端设备例如也称为车载单元(on-board unit,OBU)。
另外,上文中提到的车到一切(vehicle to everything,V2X),就是车与外界进行互联互通,这是未来智能汽车、自动驾驶、智能交通运输系统的基础和关键技术。V2X将在已有的D2D技术的基础上对V2X的具体应用需求进行优化,需要进一步减少V2X设备的接入时延,解决资源冲突问题。

图4为本申请实施例提供的一种控制信息传输方法的流程示意图,该方法应用于包括第一设备和第二设备的通信系统中,参见图4,该方法包括以下几个步骤。
S301:第一设备根据物理层源标识K和第一设备的标识Mi确定第一序列的循环移位值,或者根据资源的索引Fi和第一设备的标识Mi确定第一序列的循环移位值。图4中以根据物理层源标识K和第一设备的标识Mi确定第一序列的循环移位值为例进行说明。
其中,第一设备和第二设备可以为同一个组中的不同设备,第一设备可以为基站或者用户设备,第二设备也可以为基站或者用户设备,关于基站和用户设备的具体类型可以参见上文中关于基站和用户设备的相关描述。在本申请实施例中,第二设备可以通过组播的方式与多个成员设备之间进行通信,第一设备可以是多个成员设备中的任意一个成员设备。例如,以图5所示的用户组为例,第二设备UE0可以与多个成员设备UE1至UEM之间进行通信,第一设备可以为UE1至UEM中的任意一个成员设备。
另外,该资源可以是多个成员设备用于发送控制信息的资源集中的一个资源,该资源的索引Fi为该资源在该资源集中的资源索引,可用于标识和索引该资源。该资源集中可以包括多个资源,多个资源中的每个资源可以对应有一个资源索引。可选的, 该资源的索引Fi可以通过下述方式来确定:Fi=Mi mod Z,其中Z为该资源集中包括的频域资源和/或序列循环移位资源的总,mod表示取模操作;或者,Fi=(K+Mi)mod Z,其中K为第一设备从第二设备接收到的物理层源标识,Z为发送该控制信息的资源集中包括频域资源和/或序列循环移位资源的总数量,mod表示取模操作。可选的,本申请中的K对应的英文解释可以描述为“K is a physical layer source ID provided by SCI scheduling the PSSCH reception”。
可选的,该资源可以包括时域资源、频域资源、码域资源或者空域资源中的任意一种或多种。该时域资源是指在时域上所占用的资源,其单位为符号(symbol)、时隙(slot)或子帧等,具体可以通过符号、时隙或子帧等来表示;该频域资源是指在频域上所占用的资源,其单位为子信道、资源块、子载波、资源池、载波或带宽部分,具体可以通过子信道、资源块、子载波、资源池、载波或带宽部分等来表示;该码域资源是指在码域上所占用的资源,其单位为序列或码道,具体可以通过序列或码道等来表示;该空域资源是指空域上所占用的资源,其单位为空间的波束方向、空间层或预编码向量,具体可以通过波束方向、空间层或预编码向量等来表示。上述可能的实现方式中,可以尽可能地为同一组内的成员设备选择不同的资源,以保证资源集中的每个资源都能被充分利用,从而减小多个成员设备需要的循环移位值的数量,以提升检测性能。
具体的,该资源可以包括上述四种资源中的任意一种资源,例如,该资源仅包括时域资源,或者该资源仅包括频域资源,或者该资源仅包括码域资源,或者该资源仅包括空域资源;该资源可以包括上述四种资源中的任意两种资源,例如,该资源包括时域资源和频域资源,或者该资源仅包括时域资源和码域资源,或者该资源仅包括时域资源和空域资源;该资源可以包括上述四种资源中的任意三种资源,例如,该资源包括时域资源、频域资源和码域资源,或者该资源包括时域资源、频域资源和空域资源,或者该资源包括频域资源、码域资源和空域资源;该资源可以同时包括上述四种资源,即该资源包括时域资源、频域资源、码域资源和空域资源。
再者,第一设备的标识可以是高层消息指示的标识,也可以是物理层消息指示的标识,还可以是应用层消息指示的标识,本申请对此不做限定。可选的,第一设备的标识Mi可以为以下任一种:标识第一设备的编号,第一设备的成员标识,接收第二设备发送的第一数据的设备标识(对应的英文可以为“Mi is the identity of the UE receiving the PSSCH as indicated by higher layers.”)。其中,标识第一设备的编号可以是标识第一设备传输信息时的标识或物理标识。例如,可以是以下中的任意一种:第一设备发送控制信息时的控制信息的循环冗余校验(cyclic redundancy check,CRC)的掩码,RNTI、国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)、国际移动设备识别码(international mobile equipment identity,IMEI)、临时UE识别号S-TMSI、全球唯一临时UE标识(Globally Unique Temporary UE Identity,GUTI)和IP地址。具体的,当第一设备的标识Mi为标识第一设备的编号时,第一设备的标识Mi可用于在整个通信系统中唯一标识第一设备。当第一设备的标识Mi为第一设备的成员标识时,第一设备的标识Mi可用于在第一设备所在用户组的多个成员设备中唯一标识第一设备。当第一设备的标识Mi为接收第二设备发送的第一 数据的设备标识时,第一设备的标识Mi仅用于在接收第二设备发送的第一设备的多个设备中唯一标识第一设备。上述三种标识所标识的范围从大到小具体可以为:标识第一设备的编号所标识的范围大于第一设备的成员标识所标识的范围,第一设备的成员标识所标识的范围大于或等于接收第二设备发送的第一数据的设备标识。上述可能的实现方式中,可以将不同的第一设备相关的标识作为第一设备的标识Mi,从而可以灵活地标识第一设备的标识,从而提高系统的灵活性和多样性。
上述关于接收第二设备发送的第一数据的步骤,具体可以参见图6所示,在S301之前,该方法还包括S300:第一设备接收第二设备发送的第一数据。
其中,第二设备可以通过组播的方式向用户组中的多个成员设备发送第一数据,第一设备可以为多个成员设备中的任意一个成员设备,第二设备也可以通过组播的方式向用户组中多个成员设备中的部分成员设备发送第一数据,第一设备可以为这部分成员设备中的任意一个成员设备。这样当第二设备通过组播的方式发送第一数据时,第一设备可以接收第二设备发送的第一数据。
第一设备接收第二设备发送的第一数据具体可以存在两种情况,即第一设备正确接收第一数据和第一设备未正确接收第一数据,第一设备正确接收第一数据可以是指第一设备接收到第一数据的译码结果正确,第一设备未正确接收第一数据可以是指第一设备未接收到第一数据或者第一设备接收到的第一数据的译码结果不正确。第一设备可以通过应答信息向第二设备反馈第一数据的接收情况时,该应答信息可以包括肯定应答(acknowledge,ACK)和否定应答(non-acknowledge,NACK),该肯定应答用于指示第一数据接收成功,该否定应答用于指示第一数据接收失败。
在一种可能的实现方式中,上述S301中第一序列的循环移位值可以包括第一序列的第一循环移位值或第一序列的第二循环位值,第一序列的第一循环移位值可以对应第一设备的肯定应答(即第一设备正确接收第一数据),第一序列的第二循环移位值可以对应第一设备的否定应答(即第一设备未正确接收第一数据),第一循环移位值和第二循环移位值可以构成一个循环移位对,第一循环移位值与第二循环移位值不同。
具体的,若第一设备正确接收第一数据,则第一设备可以根据该资源的索引Fi和第一设备的标识Mi确定第一序列的第一循环移位值,若第一设备未正确接收第一数据,则第一设备可以根据该资源的索引Fi和第一设备的标识Mi确定第一序列的第二循环移位值。
需要说明的是,第一设备根据该资源的索引Fi和第一设备的标识Mi确定第一序列的第一循环移位值或第二循环移位值的具体过程可以参见下文中第一种方式至第三种方式的详细描述,本申请实施例在此不再赘述。
S302:第一设备根据该循环移位值生成第一序列。
当第一设备确定该循环移位值时,第一设备可以根据该循环移位值对第一序列的基序列进行循环移位以生成第一序列。具体的,若第一设备正确接收第一数据,则第一设备根据第一循环移位值对第一序列的基序列进行循环移位以生成第一序列;若第一设备未正确接收第一数据,则第一设备根据第二循环移位值对第一序列的基序列进行循环移位以生成第一序列。
需要说明的是,第一序列的基序列可以是预定义的,或者第一序列的基序列是第 一设备根据根序列号生成的基序列,该根序列号可以是预定义的。另外,第一序列的长度或者第一序列的基序列的长度可以是预定义的,例如,第一序列的长度或者第一序列的基序列的长度可以为12。在实际应用中,第一序列的基序列可以是ZC序列,或预定义的序列,例如通过计算机搜索、数学分析等给出的具有优良相关特性的序列等。
S303:第一设备在该资源上通过第一序列向第二设备发送控制信息。
该控制信息可以为对应第二设备发送的第一数据的应答信息,即第一设备通过S303向第二设备发送应答信息,该应答信息包括肯定应答和否定应答。具体的,若第一设备正确接收第一数据,则第一设备在该资源上向通过第一序列向第二设备发送肯定应答,此时第一序列是第一设备根据第一循环移位值生成的序列。若第一设备未正确接收第一数据,则第一设备在该资源上向通过第一序列向第二设备发送否定应答,此时第一序列是第一设备根据第二循环移位值生成的序列。在本申请实施例中,当不同用户设备在相同的资源或资源集上以码分复用的方式分别发送肯定的应答ACK或否定的应答NACK时,同一个用户设备的ACK和NACK之间所使用的循环移位值不同,从而实现同一用户设备对于同一数据的不同应答信息的传输,以便于接收应答消息的用户设备能够有效地区分出当前检测到的是ACK的应答还是NACK的应答,减少错误检测的概率,提升系统性能。
S304:当第二设备接收到该控制信息时,第二设备根据第一序列获取第一设备的控制信息。
当第二设备接收到该控制信息时,第二设备可以使用第一序列对该控制信息进行解码进而获取到该控制信息。具体的,当该控制信息对应第一数据的应答信息时,若第二设备使用第一序列的第一循环移位值生成的第一序列解码得到该控制信息,则得到的该控制信息即为第一数据的肯定应答;若第二设备使用第一序列的第二循环移位值生成的第一序列解码得到该控制信息,则得到的该控制信息即为第一数据的否定应答。
需要说明的是,第二设备确定第一序列的循环移位值的具体过程可以与第一设备确定第一序列的循环移位值的具体过程相同或类似,下面以S301中第一设备确定第一序列的循环移位值的步骤为例进行详细说明。

需要说明的是,接收侧(即第二设备)检测上述控制信息使用的第一序列的生成过程相同与上述发送侧(即第一设备)的过程类似,具体可以参见上文中的相关描述,本申请实施例在此不再赘述。
在本申请实施例中,第一设备或者第二设备可以根据第一控制信息指示的物理层源标识K和第一设备的标识Mi确定第一序列的循环移位值来灵活地成生用于序列的循环移位值,并且通过相应的方式可以控制不同收发UE之间的循环移位的间隔,从而保证其间隔尽可能的分开,以确定通过第一序列发送的控制信息的检测性能。

在第1种实施例中,对于用户组中不同成员设备的第一序列的循环移位值的选取,可以按照先依次选择资源集中不同的资源,后依次选择循环移位对中不同的循环移位对的顺序来执行。同时,对于同一循环移位对中的第一循环移位值和第二循环移位值的选取上,可以尽可能地保证这两个循环移位值之差较大。
具体的,若该资源的索引Fi=(K+Mi)mod Z,则第一设备可以根据Fi、Mi和Y通过如下公式(1-1)或者公式(1-2)确定第一序列的第一循环移位值CSi_A。其中,b为正整数,Ncs为循环移位的数量,Ncs为正整数,C为整数。作为一种特例,可选的C可以取值为0。

在本申请中,可选的,a=Ncs/2。其好处是用于做ACK应答与NACK应答的循环移位的间隔达到最大,从而可以实现最小的ACK到NACK的或NACK到ACK的错检。可选的,Ncs可以取值4、6、8或12等,在本申请中,可选的,Ncs可以是协议预定义的或信令配置的,如配置在资源池上的。在本申请中,可选的,b可以取值为1、2或3等。可选的,b的取值为(Ncs/Y),其中Y为正整数,例如取值为1、2、3、4 或6等。在本申请中,可选的,Y为序列的循环移位对的数量,可以是预定义的或信令配置的。

本申请实施例还提供另一种控制信息传输方法,该方法包括以下步骤。
S11:第一设备根据第一控制信息的CRC、第一控制信息调度的数据的CRC和第一控制信息中的至少一种确定第一序列的循环移位。
其中,该循环移位由第一反馈信息关联的第一控制信息的CRC和/或第一控制信息调度的数据的CRC确定;或者,该循环移位由第一反馈信息关联的第一控制信息和/或第一控制信息指示的信令中的一种或多种的组合确定。这里第一反馈信息与第一控制信息的关联关系为:第一反馈信息是指第一控制信息调度的数据的反馈信息,也可以称为第一反馈信息与第一控制信息调度的数据相对应。

可选地,对于接收侧(即第二设备),有对应的操作和过程:
S21:接收第一设备通过第一序列发送的第一反馈信息。
其中,第一反馈信息与第一控制信息调度的数据相对应,第一序列的循环移位是根据第一控制信息的循环冗余校验CRC、第一控制信息调度的数据的CRC和第一控制信息中的至少一种确定的。
其中,所述循环移位由所述第一反馈信息关联的第一控制信息和/或第一控制信息调度的数据的CRC确定。
S22:所述第二设备根据所述第一序列检测所述第一反馈信息。
需要说明的是,接收侧(即第二设备)检测上述第一反馈信息使用的第一序列的生成过程相同与上述发送侧(即第一设备)的过程类似,具体可以参见上文中的相关描述,本申请实施例在此不再赘述。
可选的,作为一个实施例,以第一设备UE1,第二设备UE2,UE1和UE2在V2X或侧行链路上的通信为例做进一步说明。
UE1接收来自UE2发送的侧行链路物理层共享信道(physical sidelink share channel,PSSCH)上的数据。可选的,UE2发送PSSCH数据时会有第一控制信息SCI(侧行控制信息)与PSSCH在同一个时隙上发送。可选的,第一控制信息用来发送指示PSSCH中的数据传输时使用的发送参数的信息。第一控制信息中的信息可以承载在第一级控制信息中,也可以承载在第二级控制信息中。通常,第一级控制信息的发送时间不晚于第二级控制信息的发送时间。可选的,第一级控制信息用于UE1来确定接收PSSCH中的数据的传输参数,例如:时域资源的指示信息、频域指示信息,MCS值、和/或DMRS样式的指示信息。可选的,第一级控制信息还可以用于UE1确定自己的传输资源。可选地,第二级控制信息包括:源标识的指示信息,目的标识的指示信息,UE2的位置信息等中的一种或多种的组合。可选地,第二级控制信息可以提供进一步地用于UE1来解调UE2发送的PSSCH中的数据的参数。
可选地,UE1在接收到第一控制信息和PSSCH之后,需要向UE2发送是否成功检测到PSSCH的应答信息。可选的,一种方式是使用第一序列来发送这个应答信息。可选的,应答信息可以仅是一个状态,例如UE1仅发送肯定的应答信息,或者仅发送否定的应答信息。比如,当UE1仅发送肯定的应答信息时,若UE1检测到数据接收正确时,UE1向UE2发送应答信息ACK,若UE1没检测到或检测到数据接收错误,UE1不发送应答信息。又比如,当UE1仅发送否定的应答信息时,若UE1检测到数据接收错误时,UE1向UE2发送应答信息NACK,若UE1没检测到或检测到数据接收正确,UE1不发送应答信息。可选地,应答信息可以是两个不同的状态,ACK或NACK,比如,若UE1检测到数据接收正确时,UE1向UE2发送应答信息ACK,若UE1检测到数据接收错误,UE1向UE2发送应答信息NACK。

Figure PCTCN2020084303-appb-000108
第一标识的生成方法如上面的示例所示。其中一种是使用第一级控制信息的CRC,和/或第二级控制信息的CRC,和/或数据的CRC。CRC本身是用来做控制或数据的接收成功与否的校验的。因为CRC生成的比特与待发送的数据或控制信息密切相关,因此具有一定的相关性和随机性,使用CRC可以作为生成第一序列的参数。UE1在检测成功第一级控制信息、第二级控制信息、和/或数据时,对应的信息或数据可以按预定义的CRC检验多项式以及检测到的信息来生成相应的CRC相关的第一标识
