应当理解的是,在本文中提及的“若干个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。为了便 于理解,下面先对本申请涉及的应用场景进行简单介绍。
请参考图1,其示出了本申请一示例性实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个终端110以及基站120。
其中,终端110可以是指向用户提供语音和/或数据连通性的设备。终端110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,终端110可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户装置(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户终端(User Equipment,UE)。或者,终端110也可以是无人飞行器的设备、车载设备等。
基站120可以是无线通信系统中的网络设备。其中,该无线通信系统也可以是5G系统,又称新空口(New Radio,NR)系统。或者,该无线通信系统也可以是5G系统的再下一代系统。
可选的,基站120可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(Central Unit,CU)和至少两个分布单元(Distributed Unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本申请实施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可选的,上述无线通信系统还可以包含网络管理设备130。
基站120可以分别与网络管理设备130相连。其中,网络管理设备130可以是无线通信系统中的核心网设备,比如,该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备130的实现形态,本申请实施例不做限定。
其中,在上述图1所示的无线通信场景中,终端向基站发送数据时,可以在PUCCH和PUSCH中发 送对应的数据,相应的,基站可以在PUCCH和PUSCH中接收终端发送的数据。以PUCCH中承载UCI信息为例,基站通过物理下行共享信道(Physical Downlink Shared Channel,PDSCH)向终端发送PDSCH数据后,终端需要对此次基站发送的PDSCH数据是否正确接收进行反馈,其中,终端可以通过PUCCH进行确认应答(Acknowledge,ACK)或者否定应答(Non-Acknowledge,NACK)反馈。或者,基站可以指示终端进行周期或准周期的信道状态信息(Channel State Information,CSI)测量,终端需要通过PUCCH向基站反馈CSI测量结果。对于反馈的ACK、NACK或者CSI测量结果这些信息,均可以称为UCI信息。当承载UCI信息的信道和PUSCH发生冲突时,终端可以将UCI信息复用在PUSCH上进行传输。
为了提高PUSCH的传输可靠性,NR系统还引入了PUSCH的重复传输,即,将携带相同数据的PUSCH在一段时间内多次传输。从时域资源的角度看,在R15中,PUSCH的重复传输是基于时隙级的重复传输,而在R16中,引入了跨时隙的PUSCH重复传输,也就是基站通过配置每次重复传输占用的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号长度及重复传输的次数来指示每次重复传输所占用的时域位置。
其中,终端在PUSCH中进行重复传输时,终端在PUSCH中实际采用的资源与基站配置的资源可能存在差异。比如,当基站配置的资源中的某次重复传输采用的资源,存在跨越时隙边界或者与基站配置的下行数据(DownLink,DL)符号发生冲突时,终端需要按照时隙边界以及该DL符号对基站配置的重复传输的资源进行分割(segment),采用分割后的PUSCH包含的资源进行传输。
其中,我们可以将基站配置的重复传输PUSCH称为:名义重复(nominal repetition)传输PUSCH,也称为名义PUSCH(nominal PUSCH)。终端对基站分配的名义PUSCH进行segment后,得到的多个PUSCH进行传输,此时的重复传输PUSCH可以称为实际重复(actual repetition)传输PUSCH,也可以称为实际PUSCH(actual PUSCH)。
请参考图2,其示出了本申请一示例性实施例涉及的一种PUSCH包含的资源的结构示意图。如图2所示,其中包含了时隙一201,时隙二202,名义PUSCH 203,实际PUSCH 204。由图2可知,基站配置的PUSCH的重复传输次数为3,起始位置为时隙一201的第6个OFDM符号,每次传输的长度为6,当终端得到基站配置的PUSCH的重复传输时,即相当于得到了名义PUSCH 203(包含名义PUSCH 1,名义PUSCH 2,名义PUSCH 3),终端可以根据PUSCH的资源情况,对名义PUSCH 203进行segment得到实际PUSCH 204(包含实际PUSCH 1,实际PUSCH 2,实际PUSCH 3,实际PUSCH 4),其中,图2中展示的实际PUSCH 204仅仅是示例性的结果,并不代表所有情况。当终端传输PUSCH数据时,可以按照实际PUSCH 204包含的资源进行传输。
对于承载UCI的信道与实际PUSCH出现碰撞时,终端如何进行数据传输,目前尚未有完善的解决方案。在一种可能实现的方式中,终端可以通过判断承载UCI的信道和名义PUSCH是否发生冲突,并在发生冲突时,在实际PUSCH上复用传输UCI。其中,终端是根据承载UCI的信道与基站配置的名义PUSCH 进行比较,如果两者发生冲突,终端可以将PUCCH中的UCI复用到实际PUSCH上进行传输。由于终端判断承载UCI的PUCCH和PUSCH是否发生冲突时,是与基站配置的名义PUSCH进行比较,当基站配置的名义PUSCH需要进行segment时,如果基站配置的名义PUSCH在segment后,实际PUSCH中可用于承载UCI的资源数量较小UCI在复用时的码率可能超过最大码率,导致基站无法正确解调,造成将UCI复用到实际PUSCH上进行传输时基站的接受率低,导致终端与基站之间信息传输的可靠性降低。
为了提供终端更好的将UCI复用在PUSCH中进行传输,提高信息传输的可靠性,本申请实施例提供了一种解决方案,可以将UCI复用在PUSCH中传输的同时减少PUSCH传输的出错率。请参考图3,其示出了本申请一示例性实施例提供的一种信息传输方法的方法流程图,该方法可以应用于上述图1所示的无线通信系统中,由该系统中的终端执行。如图3所示,该信息传输方法可以包括以下几个步骤:
步骤301,当第一信道与第三信道发生重叠,且第一信道满足第一条件时,在第一信道上对上行数据和上行控制信息进行复用传输。其中,第一信道的资源是第二信道的资源中的部分资源,第二信道是用于承载上行数据的信道,第三信道用于传输上行控制信息的信道。
其中,第二信道是网络设备配置给终端的用于承载上行数据的信道,比如,第二信道是上述图2所示的名义PUSCH,上行数据可以是承载在PUSCH中的数据。第一信道的资源是从第二信道的资源中确定出的部分资源,比如,第一信道是上述图2所示的实际PUSCH。终端在接收到nominal PUSCH后,可以按照上述图2的方式,对nominal PUSCH进行segment,从而可以确认出nominal PUSCH对应的各个OFDM符号中的actual PUSCH对应的各个OFDM符号,从而从第二信道的资源中确认出第一信道的资源。
可选的,第一信道的资源是由actual PUSCH对应的各个OFDM符号组成的。比如,在上述图2所示的时隙结构中,第一信道的资源可以是实际PUSCH 1,实际PUSCH 2,实际PUSCH 3,实际PUSCH 4各自对应的OFDM符号组成的信道资源。
可选的,第三信道是网络设备配置给终端用于承载上行控制信息的信道,比如,第三信道是上述图2所示的PUCCH信道,上行控制信息可以是承载在PUCCH中的UCI。其中,网络设备可以向终端配置PUCCH,终端得到网络设备配置的PUCCH后,可以在网络设备配置的PUCCH中传输上行控制信息。第三信道的资源可以是此次传输上行控制信息时采用的资源,也是此次传输上行控制信息时采用的各个OFDM符号组成的资源。
可选的,终端在传输上行控制信息以及传输上行数据时采用的信道可能产生重叠,即,第三信道和第一信道可能重叠,造成信道之间的冲突,如果第一信道满足第一条件,此时,终端可以将上行控制信息在第一信道上与上行数据一起进行复用传输。即,在上述发生重叠的第一信道和第二信道中,当第一信道满足第一条件时,终端可以在第一信道上对上行数据和上行控制信息进行复用传输。
可选的,第一信道与第三信道产生重叠,可以理解为第一信道的资源与第二信道的资源有重叠,或者, 第一信道的资源与第二信道的资源中各自包含的OFDM符号有重叠。
请参考图4,其示出了本申请一示例性实施例涉及的一种信道冲突的示意图。如图4所示,其中包含了第一信道401,第二信道402,第三信道403,第四信道404。其中,第一信道401与第二信道402是有重叠的,第三信道403与第四信道404是有重叠的。即本申请中,冲突与重叠是相同的意思。
在本申请实施例中,当第一信道与第三信道发生重叠时,通过判断第一信道是否满足第一条件,从而决定是否在第一信道上对上行数据和上行控制信息进行复用传输,其中第一信道的资源是第二信道的资源中的部分资源,避免了第一信道中的资源数量过小导致上行控制信息在第一信道中复用传输时码率过大的问题,提高了网络设备解调上行控制信息的准确率,从而提高了终端与网络设备之间信息传输的可靠性。
可选的,上述第一条件包括:
与第三信道重叠的多个满足复用时序要求的信道中的起始时间最早的信道;
和/或;
第一数量大于或等于目标数量,第一数量用于表示第一信道中用于传输上行数据的资源数量,或第一信道中除参考信号以外的所有资源数量或部分资源的数量。
可选的,目标数量是根据第二信道的资源数量得到的,或者,根据第一信道的资源数量得到的。
可选的,资源数量是时频资源单元RE、子载波、OFDM符号中的任意一种资源数量。
可选的,参考信号包含解调参考信号DMRS或者相位跟踪参考信号PTRS中的至少一种参考信号。可选的,该方法还包括:
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,不发送第一信道;或者,
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,只发送第三信道;或者,
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,不发送上行控制信息;或者,
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,只在第一信道中传输上行数据;或者,
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,在第一信道中发送上行数据,在第四信道上传输上行控制信息,第四信道与第一信道不重叠;或者,
当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,在第一信道中传输上行数据,在第三信道中传输上行控制信息。
可选的,第一信道的资源是对第二信道的资源进行切割得到的。
可选的,第一信道是实际actual PUSCH,第二信道是名义nominal PUSCH。
可选的,上述上行控制信息包括:
承载针对PDSCH反馈的确认应答ACK/否认应答NACK的PUCCH,
或者,
承载PUSCH对应的上行调度请求SR的PUCCH,
或者,
承载信道状态信息CSI的PUCCH或PUSCH。
上述所有可选技术方案,均可按照任意结合形成本申请的可选实施例,本申请实施例对此不再一一赘述。
在一种可能实现的方式中,终端可以计算目标数量,利用目标数量判断第一信道是否满足第一条件。该目标数量是上行控制信息在第一信道中复用所需的资源数量。下面就以目标数量是第一条件中的数据之一为例,对上述图3所示的方案进行举例介绍。
请参考图5,其示出了本申请一示例性实施例提供的又一种信息传输方法的方法流程图,该方法可以应用于上述图1所示的无线通信系统中,由该系统中的终端执行。如图5所示,该信息传输方法可以包括以下几个步骤:
步骤501,接收网络设备配置的第二信道,该第二信道用于承载上行数据的信道。
其中,网络设备可以将终端在PUSCH中可使用的资源通过下行控制信息(Downlink Control Information,DCI)发送给终端,相应的,终端可以解调DCI中的信息,得到名义PUSCH(第二信道)。
步骤502,根据固定资源信息,从第二信道的资源中获取第一信道的资源。
其中,固定资源信息包含时隙边界、上下行配置以及不可用资源各自指示的资源信息。
其中,网络设备配置给终端的第二信道并不代表终端可以用第二信道中所有的资源。比如,网络设备需要在这些资源中的部分资源传输一些上下行配置(比如,下行链路(Downlink,DL)符号等),需要占用其中的部分资源,使得终端实际在使用第二信道的资源时,也是选择其中未被使用的资源来使用。或者,网络设备需要在第二信道的资源中的部分资源传输一些不可用资源(比如,系统数据等),也需要占用其中的部分资源,使得终端实际在使用第二信道的资源时,也是选择其中未被使用的资源来使用。
终端可以从网络设备配置的名义PUSCH的资源中选择出可用于PUSCH传输的资源,这些可用于PUSCH传输的资源即为终端确定出的实际PUSCH的资源。
请参考图6,其示出了本申请一示例性实施例涉及的一种信道的资源结构的结构示意图,如图6所示,其中包含了第一时隙601,第二时隙602,第三时隙603。名义PUSCH 604,实际PUSCH 605。由图6可知,网络设备给终端配置了一个重复传输次数为3次,传输的起始位置为第一时隙601的第11个OFDM符号,每次传输持续的长度为6个OFDM符号的PUSCH的多次传输。即对应第一时隙601的第12个OFDM符号至第三时隙603的第1个OFDM符号为网络设备配置的名义PUSCH的资源。
其中,在名义PUSCH的资源中,网络设备在第二时隙602中的第9个至第11个OFDM符号中有DL符号,而终端并不能在有DL符号的资源中传输PUSCH,因此终端实际使用的重复传输的资源中并不会包 含第二时隙602中的第9个至第11个OFDM符号。另外,由于在时隙边界处,也不能用于PUSCH的传输,终端在实际进行PUSCH传输时,也需要对名义PUSCH 504重新进行分割。
在终端对名义PUSCH 604重新进行分割后,可以得到如图6中包含的实际PUSCH 605,终端在实际对PUSCH进行传输时,可以采用实际PUSCH 605包含的资源进行传输。其中,第一信道的资源是实际PUSCH 605包含的所有的资源(即,第一时隙601中编号11的OFDM符号至第二时隙602中编号7的OFDM符号,第二时隙602中编号11的OFDM符号至第三时隙603中编号0的OFDM符号)。可选的,实际PUSCH 605包含的每个分割线也可以组成一个信道,比如,第一信道中的一个信道的资源为:第一时隙601中编号11-13的OFDM符号;第一信道中的另一个信道的资源为:第二时隙602中编号0-2的OFDM符号。以此类推,第二时隙602中编号3-7的OFDM符号也可以是第一信道中的一个信道的资源;第二时隙602中编号11-13的OFDM符号也可以是第一信道中的一个信道的资源;第三时隙603中编号0的OFDM符号也可以是第一信道中的一个信道的资源。
步骤503,当第一信道与第三信道发生重叠,且第一信道满足第一条件时,在第一信道上对上行数据和上行控制信息进行复用传输。
第三信道是传输上行控制信息的信道。比如,第三信道是网络设备配置给终端的PUCCH。终端可以判断第一信道与第三信道是否发生重叠。其中,终端判断信道重叠的方式可以参照上述图4所示的方式,此处不再赘述。
可选的,上行控制信息中也可以包含承载针对PDSCH反馈的确认应答ACK/否定应答NACK的PUCCH,或者,承载PUSCH对应的上行调度请求(Scheduling Request,SR)的PUCCH,或者,承载信道状态信息(Channel State Information,CSI)的PUCCH或PUSCH中的任意一种信息。
当第一信道与第三信道发生重叠时,终端可以判断第一信道是否满足第一条件,并在第一信道满足第一条件的情况下,在第一信道上对上行数据和上行控制信息进行复用传输。
可选的,第一条件可以如下:与第三信道重叠的多个满足复用时序要求的信道中的起始时间最早的信道;和/或;第一数量大于或等于目标数量,第一数量用于表示第一信道中用于传输上行数据的资源数量,或第一信道中除参考信号以外的所有资源数量或部分资源数量。
例如,在上述图6中,第一信道与第三信道发生重叠的信道的资源是符号11至符号13,终端可以判断该信道可以是否满足复用时序要求。和/或,终端获取第一数量,终端计算目标数量,终端判断第一数量与目标数量之间的大小关系。当该信道满足复用时序要求,第一数量大于或等于目标数量时,视为第一信道满足第一条件。
其中,第一数量用于表示第一信道中用于传输上行数据的资源数量,或第一信道中除参考信号以外的所有资源数量或部分资源数量。目标数量是根据第二信道的资源数量得到的,或者,根据第一信道的资源数量得到的。
可选的,此处的资源数量可以是时频资源单元(Resource Element,RE)、子载波、OFDM符号中的任意一种资源的数量。例如,终端可以根据第二信道中RE的个数,计算上行控制信息在第一信道上复用所需要的RE的个数(即为目标数量)。或者,终端可以根据第二信道中子载波的个数,计算上行控制信息在第一信道上复用所需要的子载波的个数。或者,终端可以根据第二信道中OFDM符号的个数,计算上行控制信息在第一信道上复用所需要的OFDM符号的个数。本申请实施例对此并不加以限定。
可选的,此处的参考信号可以包含解调参考信号(Demodulation Reference Signal,DMRS)或者相位跟踪参考信号(Phase Tracking Reference Signal,PTRS)等中的至少一种参考信号。
可选的,终端判断上述信道是否满足复用时序要求时,可以按照NR Rel-15中的规定,本申请实施例对此并不加以限定。
请参考图7,其示出了本申请一示例性实施例涉及图6的另一种第一信道与第三信道重叠的示意图。如图7所示,其中包含了第一时隙701,第二时隙702,第三时隙703。名义PUSCH 704,实际PUSCH 705。终端通过上述步骤可以获取到第一信道与第三信道中重叠的信道的资源包含第一时隙701中编号11至第二时隙702中编号2的OFDM符号。重叠的信道可以包括实际PUSCH 1和实际PUSCH 2,此时,终端可以判断实际PUSCH 1是否满足复用时序要求。和/或,终端获取第一数量,终端计算目标数量,终端判断第一数量与目标数量之间的大小关系。当实际PUSCH 1满足复用时序要求,第一数量大于或等于目标数量时,视为第一信道满足第一条件。可选的,第一数量和目标数量的获取方式与上述类似,此处不再赘述。
可选的,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,不发送第一信道;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,只发送第三信道;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,不发送上行控制信息;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,只在第一信道中传输上行数据;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,在第一信道中发送上行数据,在第四信道上传输上行控制信息,第四信道与第一信道不重叠;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,在第一信道中传输上行数据,在第三信道中传输上行控制信息。可选的,上述不发送第一信道可以理解为不发送第一信道中承载的数据,发送第三信道可以理解为发送第三信道中承载的数据。
比如,在上述图6中,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端不发送实际PUSCH 1;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端只发送PUCCH;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端不发送上行控制信息;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端只在实际PUSCH 1中传输上行数据;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端在实际PUSCH 1中发送上行数据,在实际PUSCH 2上传输上行控制信息;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端在实际PUSCH 1中传输上行数据,在PUCCH中传输上行控制信息。
又例如,在图7中,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端不发送实际PUSCH 1;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端只发送PUCCH;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端不发送上行控制信息;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端只在实际PUSCH 1中传输上行数据;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端在实际PUSCH 1中发送上行数据,在实际PUSCH 3上传输上行控制信息;或者,当第一信道与第三信道发生重叠,且第一信道不满足第一条件时,终端在实际PUSCH 1中传输上行数据,在PUCCH中传输上行控制信息。
在本申请实施例中,当第一信道与第三信道发生重叠时,通过判断第一信道是否满足第一条件,从而决定是否在第一信道上对上行数据和上行控制信息进行复用传输,其中第一信道的资源是第二信道的资源中的部分资源,对应目标数量的计算,是根据基于segment前的PUSCH中的资源数量来计算目标上行信息所需要的资源数目,由于segment前的PUSCH的资源所包含的资源数量比segment后的PUSCH的资源所包含的资源数量多,避免了第一信道中的资源数量过小导致上行控制信息在第一信道中复用传输时码率过大的问题,提高了网络设备解调上行控制信息的准确率,从而提高了终端与网络设备之间信息传输的可靠性。
