Description
本发明涉及通信技术领域,尤其涉及一种上行控制信道的资源映射方法及装置。
第五代移动通信技术(5th-Generation,5G)通信系统采用正交频分复用(orthogonal frequency division multiplexing,OFDM)技术。基站(eNodeB,简称eNB)通过有限个OFDM符号向用户设备(user equipment,UE)发送信息。在5G通信系统中,eNB向UE发送信息时,可在一个时隙(slot,例如slot0)内发送信息,还可在该slot中包括的mini slot内发送优先级更高的业务数据。UE接收到eNB发送的信息之后,需要分别对eNB在slot0上发送的数据(设为数据1)进行反馈,以及eNB在mini slot上发送的数据(设为数据2)进行反馈。在5G通信系统中,UE接收到eNB发送的信息之后,通过物理上行链路控制信道(physical uplink control channel,PUCCH)向eNB反馈上行控制信息(uplink control information,UCI)等信息。
现有技术中,UE反馈UCI的PUCCH占用的频域资源被放置在上行系统带宽的两段,PUCCH占用的频域资源被放置在上行系统带宽中的位置与PUCCH包含的信息对应的下行控制信息(downlink control information,DCI)相关。然而,在5G通信系统中,eNB向UE发送信息的时候,不再是一个slot内只有一个DCI,而可能是一个slot中有多个DCI,其中包括mini slot对应的DCI。现有技术中,多个slot对应的多个DCI的PUCCH占用的频域资源被将被放置在上行系统带宽中的相同位置,进而导致PUCCH资源位置使用冲突,进而导致UE传输UCI发生错误,信息传输错误率高,适用性低。

下面结合本发明实施例中的附图对本发明实施例进行描述。
本申请各实施例中的接入网设备可以是任意一种具有无线收发功能的设备,包括但不限于:基站(NodeB)、演进型基站(evolved NodeB,eNB)、5G通信系统中的基站、未来通信系统中的基站或网络设备、WiFi系统中的接入节点、无线中继节点以及无线回传节点等。以下各实施例将以eNB为例进行说明。本申请各个实施例中所描述的终端设备也可以称之为UE、终端(terminal)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等。以下各实施例将UE为例进行说明。UE也可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、中继设备等等。本申请的实施例对应用场景不做限定。
图1是本申请的实施例应用的5G通信系统的架构示意图。如图1所示,该通信系统包括射频拉远头(remote radio head,RRH)、eNB1、eNB2和UE等。其中,RRH是用于移动宽带网络基站中的新技术设备,主要效益在于提升既有讯号传输效率,并且在更容易建置的网络架构下,扩大其网络覆盖率。eNB1和eNB2可通过无线连接或者有线连接或者其他连接方式与UE建立连接,本申请实施例将以eNB1和eNB2中的任意一个为例进行说明,以下描述将统称为eNB。UE可以是静止的也可以是移动的,具体可根据实际应用场景确定。图1只是示意图,该通信系统中还可以包括其它网络设备和/或其它终端设备,在图1中未予以画出,在此不做限制。
本申请的实施例可以适用于下行数据传输,也可以适用于上行数据传输,还可以适用于设备到设备(device to device,D2D)的数据传输。对于下行数据传输,数据的发送设备是基站,对应的数据接收设备是UE。对于上行数据传输,数据的发送设备是UE,对应的 数据接收设备是基站。对于D2D的数据传输,数据的发送设备是UE,对应的数据接收设备也是UE。具体可根据实际应用场景确定,本申请的实施例对此不做限定。
在5G通信系统中,eNB向UE发送信息时,在频域上占用的子载波间隔可以包括15千赫兹(KHz),或者30KHz,或者240KHz等,并且频段长度不同的子载波间隔对应的时域上的资源长度也不同,即eNB用以向UE发送信息的OFDM符号在时域上占用的时长与其在频域上占用的子载波间隔成反倍数关系。例如,假设eNB用于向UE1发送信息的OFDM符号(设为7个OFDM符号)在频域上占用的子载波间隔为15KHz,7个OFDM符号在时域上占用的时长为0.5ms。若eNB用于向UE2发送信息的OFDM符号(设为7个OFDM符号)在频域上占用的子载波间隔为30KHz,则7个OFDM在时域上占用的时长为0.25ms。
针对15KHz的子载波间隔,一个slot由7个OFDM符号组成,时长为0.5ms。在5G通信系统中,eNB和UE的工作模式分为时分双工(Time Division Duplexing,TDD)和频分双工(Frequency Division Duplexing,FDD)两种模式。其中,在FDD模式时,eNB向UE传输数据的下行传输和UE向eNB传输数据的上行传输中,eNB和UE分别工作在不同的频带上。如图2,是本发明实施例提供的FDD模式的帧结构示意图。如图2,在FDD模式下,eNB工作在下行(downlink,简称DL)子载波1上,UE工作在上行(uplink,简称UL)子载波2上。以15KHz的子载波间隔为例,子载波1的每个slot(如slot0)包括7个OFDM符号。Slot0中还包括一个mini slot,mini slot中包括2个OFDM符号。eNB在mini slot上下发给UE的数据包(设为数据包1),UE可在子载波2的slot0中的short PUCCH上反馈数据包1的接收状态。eNB在slot0的最后一个符号结束时下发给UE的数据包(设为数据包2),UE可在子载波2的slot1中的long PUCCH或者short PUCCH反馈数据包2的UCI。
如图3,是本发明实施例提供的TDD模式的帧结构示意图。如图3,在TDD模式时,eNB和UE共享一个频带,只是eNB向UE传输数据与UE向eNB传输数据分别工作在不同的OFDM符号上。其中,在子载波1的slot0中还有一个特殊的OFDM符号(如标记为4S的OFDM符号,即slot0包括的7个OFDM符号中的第5个),特殊的OFDM符号中的第一部分采样点用于DL数据传输,第二部分采用点为gap不使用,第三部分采样点用于UL数据传输。在5G通信系统中,short PUCCH在时域上占据的OFDM符号个数为1个或者2个,long PUCCH在时域上占据的OFDM符号个数最小为4个,最大可能达到14个,具体可根据实际应用场景确定,在此不做限制。
在5G通信系统中,如上图2或图3所示的数据传输模式中,DL子载波的slot0中还包括一个mini slot。eNB在mini slot向UE下发的信息可对应一个DCI,在slot0的最后一个符号完成下发的数据可对应另一个DCI。即在该工作模式中,eNB向UE发送信息的时候,不再是一个slot内只有一个DCI,而可能是一个slot(例如slot0)中有多个DCI(例如2个DCI),其中包括mini slot对应的DCI。此时,若两个DCI采用相同的CCE索引,则将导致多个相同索引编码的CCE在相同的PUCCH频域资源位置使用资源,导致PUCCH不够使用,进而导致UE传输UCI发生错误,信息传输错误率高,适用性低。
此外,在5G通信系统中,UE向eNB发送的UCI可包括混合自动重传请求(hybrid automatic repeat reQuest,HARQ)反馈信息、信道状态信息(channel state information,CSI) 和调度信息(scheduling request,SR)等。其中,上述HARQ反馈信息可包括否定应答(negative acknowledgement,NACK)和肯定应答(acknowledgement,ACK)等信号。HARQ反馈具有基于slot的定时关系,例如,UE从eNB获得数据包之后,可根据获取数据包的时隙和上述定时关系获取对该数据包的接收状态进行HARQ反馈的时隙;或者UE发送数据包给eNB之后,可根据上述定时关系和数据包发送的时隙确定获取eNB的反馈信息的时隙。针对PUCCH占用的时域资源,现有技术通过eNB直接将PUCCH占用的时域资源的信息发送给UE,信令开销大,eNB连接的UE越多,信令开销越大,实现成本越高。
本发明实施例提供了一种上行控制信道的资源映射方法及装置,UE可根据eNB发送的或者预配置的PUCCH的资源配置信息确定PUCCH资源,并在该PUCCH资源上发送UCI。具体实现中,上述确定的PUCCH资源可为PUCCH的时域位置和/或频域位置,其中,上述时域位置具体可为发送UCI的时隙,和/或发送UCI的时隙中的OFDM符号等。上述时域位置的具体表现形式可根据实际应用场景确定,在此不做限制。上述资源配置信息由包括基于UE的DCI所在资源的时域信息和/或频域信息的参数设置得到,和/或包括基于UE的PDSCH数据包所在资源的时域信息和/或频域信息的参数设置得到。UE根据DCI或者PDSCH数据包所在资源的时域信息和/或频域信息的参数设置的信息确定PUCCH资源,可提高用于传输UCI的PUCCH资源与资源配置信息的关联性,可降低PUCCH资源的占用冲突,进而可提高UCI传输的准确性,降低数据传输的信令开销,适用性更高。
需要说明的是,本申请中的UCI包括HARQ反馈信息(包括HARQ-ACK和/或HARQ-NACK)、信道状态信息参考信号(channel state information reference signal,CSI-RS)信息、缓存状态报告信息,波束ID信息,调度请求信息中的至少一种信息。上述CSI-RS信息包括信道状态指示信息、信道质量指示信息、预编码矩阵指示信息、秩指示信息、信道状态信息资源指示信息、信道状态信息干扰测量信息中的至少一种信息。
本申请中的HARQ反馈信息是基于一个或者多个传输块的反馈信息,或者是基于一个或者多个码块的反馈信息,或者是基于传输块和码块的组合的反馈信息。码块从属于和它一起发送的传输块,或者多个码块来自一个传输块。或者码块不从属于和它一起发送的传输块,或者多个码块来自不同的传输块。
参见图4,是本发明实施例提供的上行控制信道的资源映射方法的流程示意图。本发明实施例提供的方法包括步骤:
S401,UE获取上行控制信道的资源配置信息。
S402,UE基于所述资源配置信息确定上行控制信道资源,并在所述上行控制信道资源上发送上行控制信息。
在一些可行的实施方式中,eNB可依据UE的DCI占用的时频资源为UE分配PUCCH上行资源,以便将不同UE的UCI放置在不同的位置,进而可向UE发送PUCCH的资源配置信息,以供UE查找用于传输UCI的PUCCH资源。其中,上述UE的DCI占用的时频资源具体可为DCI占用的OFDM符号等。即,上述资源配置信息可由包括基于UE的DCI所在资源的时域信息和/或频域信息的参数设置得到。上述资源配置信息也可由包括基于UE的PDSCH数据包所在资源的时域信息和/或频域信息的参数设置得到。其中,上述 PUCCH的资源配置信息也可由通信协议等约定方式预先配置得到,eNB和UE均可根据通信协议等约定方式获取上述PUCCH资源配置信息,在此不做限制。eNB可通过高层信令通知UE根据上述资源配置信息确定发送UCI的PUCCH资源等,具体通知方式可根据实际应用场景的需求确定,在此不做限制。以下实现方式将以eNB向UE下发资源配置信息为例进行说明。DCI所在资源的时域信息和/或频域信息更具体为,DCI所在资源的时域信息,或者DCI所在资源的频域信息,或者DCI所在资源的时域信息和频域信息。
在一些可行的实施方式中,针对不同表现形式的资源配置信息,UE可采用不同的方式确定用以传输UCI的PUCCH资源。下面将分别对不同表现形式的资源配置信息,UE确定PUCCH资源所采用的方式进行说明。

在一些可行的实施方式中,eNB可向UE发送资源配置信息,通过上述资源配置信息指示UE在相应的PUCCH资源上发送UCI。UE接收到基站发送的资源配置信息之后,则可根据上述资源配置信息确定用于传输UCI的PUCCH资源。具体实现中,上述资源配置信息包括DCI占用的OFDM符号信息对应的资源偏移值信息,或者DCI占用的子载波间隔(subcarrier spacing,SCS)信息对应的资源偏移值信息,或者DCI占用的OFDM符号所在的SCS信息对应的资源偏移值信息。UE可根据上述任一表现形式的资源偏移值信息确定用于传输UCI的PUCCH资源。具体实现中,上述DCI占用的OFDM符号信息对应的资源偏移值信息具体可为DCI占用的每个或者指定个数的下行OFDM符号对应的资源偏移值信息。例如,在如图2所示的传输模式中,UE的DCI占用了子载波1中的slot0包括的OFDM符号,其中,可预先配置slot0中的前2个OFDM符号对应一个Nl(例如Nl1),slot0中的mini slot包括的2个OFDM符号对应一个Nl(例如Nl2)。其中,上述Nl1或者Nl2则为上述下行OFDM符号对应的PUCCH资源偏移值。Nl1或者Nl2为2个OFDM符号对应的PUCCH资源偏移值。具体实现中,也可配置每个OFDM符号对应一个PUCCH资源偏移值,即每个OFDM符号对应一个Nl。
DCI占用的OFDM符号信息也可以为DCI占用的时隙类型信息。具体实现中,上述DCI占用的时隙类型信息对应的资源偏移值信息具体可为DCI占用的每个时隙类型信息对应的资源偏移值信息。例如,在如图2所示的传输模式中,UE的DCI占用了子载波1中的slot0中的资源,利用slot0的资源发送数据包,对应一个Nl(例如Nl1),slot0中的mini slot包括的2个OFDM符号对应一个Nl(例如Nl2)。其中,上述Nl1和Nl2则为上述DCI占用的2个时隙类型对应的PUCCH资源偏移值。Nl1或者Nl2为2个时隙类型对应的PUCCH资源偏移值。可选的,上述Nl1和Nl2对应的2个时隙类型的可以相同,或者不同。可选的,上述Nl1和Nl2对应的2个时隙类型占据不同的时域和/或频域资源。可选的,上述Nl1和Nl2对应的2个时隙类型可以对应的时域资源可以交叠或者不交叠。可选的,上述Nl1和Nl2对应的2个时隙类型,可以占据相同的时隙,或者不同的时隙。上述时隙类型以及各个时隙类型占用的资源情况可以是上述各种可选方案的组合,具体可根据实际应用场景需求确定,在此不做限制。
具体实现中,上述资源配置信息包括终端设备的时隙类型信息对应的资源偏移值信息,或者上述资源配置信息包括终端设备的下行共享信道数据包所在资源的时域信息和/或频 域信息对应的资源偏移值信息。终端设备的下行共享信道数据包所在资源的时域信息和/或频域信息,更具体的为终端设备的下行共享信道数据包所在资源的时域信息,或者终端设备的下行共享信道数据包所在资源的频域信息,或者为终端设备的下行共享信道数据包所在资源的时域信息和频域信息。终端设备可根据上述任一表现形式的资源偏移值信息确定用于传输UCI的PUCCH资源。终端设备的占用了子载波1中的slot0中的资源,利用slot0的资源发送数据包,对应一个Nl(例如Nl1),slot0中的mini slot包括的2个OFDM符号对应一个Nl(例如Nl2)。其中,上述Nl1和Nl2则为上述终端设备的2个时隙类型对应的PUCCH资源偏移值。Nl1或者Nl2为2个时隙类型对应的PUCCH资源偏移值。可选的,上述Nl1和Nl2对应的2个时隙类型的可以相同,或者不同。可选的,上述Nl1和Nl2对应的2个时隙类型占据不同的时域和/或频域资源。可选的,上述Nl1和Nl2对应的2个时隙类型可以对应的时域资源可以交叠或者不交叠。可选的,上述Nl1和Nl2对应的2个时隙类型,可以占据相同的时隙,或者不同的时隙。上述时隙类型以及各个时隙类型占用的资源情况可以是上述各种可选方案的组合,具体可根据实际应用场景需求确定,在此不做限制。
具体实现中,上述资源配置信息包括终端设备的下行共享信道数据包所在资源的时域信息和/或频域信息对应的资源偏移值信息。终端设备可根据上述任一表现形式的资源偏移值信息确定用于传输UCI的PUCCH资源。终端设备的占用了子载波1中的slot0中的下行共享信道数据包时域和/或频域资源,利用slot0的资源发送数据包,对应一个Nl(例如Nl1),slot0中的mini slot包括另一个下行共享信道数据包时域和/或频域资源,即minislot中的2个OFDM符号包含了一个数据包对应了一个Nl(例如Nl2)。其中,上述Nl1和Nl2则为上述终端设备的2个下行数据包对应的PUCCH资源偏移值。Nl1或者Nl2为2个下行数据包对应的PUCCH资源偏移值。可选的,上述Nl1和Nl2对应的2个数据包类型的可以相同,或者不同。可选的,上述Nl1和Nl2对应的2个数据包占据不同的时域和/或频域资源。可选的,上述Nl1和Nl2对应的2个数据包可以对应的时域资源可以交叠或者不交叠。可选的,上述Nl1和Nl2对应的2个数据包,可以占据相同的时隙,或者不同的时隙。上述数据包类型以及各个数据包占用的资源情况可以是上述各种可选方案的组合,具体可根据实际应用场景需求确定,在此不做限制。
具体实现中,UE可根据上述资源偏移值信息获取用以确定PUCCH资源的资源偏移值,并根据承载UE的DCI的资源单位索引值确定PUCCH资源。具体实现中,若eNB所采用的数据传输方式为分布式传输,则可根据如下表达式1或者表达式3确定PUCCH资源。若eNB所采用的数据传输方式为集中式传输,则可根据如下表达式2或者表达式4确定PUCCH资源。
在上述表达式1,2,3,4中,n
RU指代资源单位索引值,也可以表示资源集合q中的资源单元索引值。具体实现中,上述n
RU具体可为n
CCE,也可为其他资源表现形式对应的资源单元索引值。n
RU,q表示资源集合q中的资源单元索引值。资源单位包括有限个资源元素(resource element,RE),或者有限个资源元素组(resource element group,REG),或者有限个资源块(resource block,RB),或者有限个CCE,具体可根据实际应用场景确定。上述
为PUCCH的资源单元索引信息。PUCCH的资源单元索引信息可用于查找对应的PUCCH。k为PUCCH的格式类型。p为天线的端口号和/或波束号相关数值。
为与用户设备相关的一个偏移量,也可以为与用户设备的资源集合q相关的一个偏移量。q为DCI所在的资源集合。
指代资源集合q中有限个RB所包括的资源单元的个数。需要说明的是,上述k指代的PUCCH的格式类型可以为不同长度PUCCH相关的格式类型,或者为所有长度PUCCH相关的格式类型,或者和DCI所在的资源集合相关的标识,在此不做限制。常数或者变量c和天线端口相关,和/或与波束相关。c的取值范围值可以为整数,可以为0,或者可以为1,2等,或者可以为-1,-2等。这里c也可以演变为c1和c2,c1和c2分别与天线端口和波束相关。c1和c2的取值范围和c相同或者类似。Δ
offset是和资源单位(resource unit,RU)的数据传输方式(分布式传输或者集中式传输)相关的变量。如果RU对应的控制信息是放置在一个资源集合中的,则Δ
offset是和资源集合对应的一个偏移值,或者是一个和DCI控制信息格式相关的偏移量,和/或是一个和PUCCH的UCI承载的信息内容相关的偏移量,或者是上述各种偏移值和或偏移量的有限组合。公式(2)和公式(4)中的取底运算,是因为DCI所在的资源集合采用集中式传输引起的。如果DCI所在的资源集合采用分布式传输传输,则选择公式(1)和(3)。
其中,公式(1)为最泛用的公式,这里对公式(1)的使用条件可以不做限定。和DCI占用的OFDM符号信息对应的资源偏移值信息,或者DCI占用的OFDM符号信息也可以为DCI占用的时隙类型信息对应的资源偏移值信息,可以用函数f表示。上述函数f的表现形式可包括如下表达式5、表达式6、表达式7和表达式8所示的四种中的任一种,或者 由如下四种表达式扩展得到的更多表现形式的表达式,在此不做限制。
f(N
l)=N

其中,上述表达式5表示函数f的取值可由N

l-1确定,上述表达式7表示函数f的取值可由N
1到N
l的累加值确定,上述表达式8表示函数f的取值可由N

进一步的,上述DCI占用的OFDM符号信息可以为一个具体OFDM符号信息,一个具体的连续的OFDM符号信息,一个具体的占用的下行DCI集合信息,一个具体的UE的下行控制信道信息。N
l为第l个OFDM符号,或者为第l个连续的OFDM符号,或者为第l个占用的下行DCI集合,或者为第l个UE的下行控制信道信息对应的资源偏移信息等。
需要说明的是,在上述表达式1、表达式2、表达式3、表达式4中求和指示一种可能的计算方式,具体也可通过上述各个参数单独表示或者通过其他计算方式确定,在此不做限制。
在一些可行的实施方式中,上述资源单位索引值(n
RU)的获取方式可包括一种或者多种,例如以下case1至case3所示的实现方式,具体获取方式可根据实际应用场景确定,在此不做限制。
Case1:权5
UE的DCI可由第一DCI(设为DCI1)和/或第二DCI(设为DCI2)共同承载,DCI1对应一个资源单元索引值(设为index1),DCI2也对应一个资源单元索引值(设为index2)。UE可从index1和index2中选取一个作为用以确定PUCCH资源的资源单位索引值。例如,上述index1或者index2可为资源单位索引,资源单位包括有限个RE,或者有限个REG)或者有限个RB,或者有限个CCE等。上述index1或者index2可为common搜索空间or non-common搜索空间的参数,例如,上述DCI可以为UE具体的DCI,或者可以为UE group的DCI,或者可以为Cell具体的DCI,公共搜素空间的DCI,非公共搜素空间的DCI。具体可根据实际应用场景确定,在此不做限制。
Case2:权6

其中,上述short PDSCH(短的PDSCH)和/或PDSCH为子带级别的PDSCH,或者一个或者若干个RB的集合。
Case3:
UE的DCI可由第一DCI(设为DCI1)和第二DCI(设为DCI2)共同承载,DCI1对应一个资源单元索引值(设为index1),DCI2也对应一个资源单元索引值(设为index2)。UE可根据index1和index2的预定义函数f()处理得到用以确定PUCCH资源的资源单位索引值。简单的,UE可将上述index1和index2二者之和确定为用以确定PUCCH资源的资源单位索引值,如下表达式9和表达式10所示:
n
RU,q=f(n
RU,q,DCI1,n
RU,q,DCI2)=n
RU,q,DCI1+n
RU,q,DCI2 (9)
n
RU=f(n
RU,DCI1,n
RU,DCI2)=n
RU,DCI1+n
RU,DCI2 (10)
其中,上述n
RU的含义和上述实现方式中包含的n
RU的含义一致,具体可参见上述实现方式中描述的含义,在此不再赘述。n
RU,q表示资源集合q中的资源单元索引值。n
RU,q,DCI1表示第一DCI对应的在资源集合q中的资源单元索引值。n
RU,DCI2表示第二DCI对应的在资源集合q中的资源单元索引值。n
RU,q,DCI1和n
RU,DCI2对应的资源集合可能相同或者不同。
在一些可行的实施方式中,UE也可根据上述资源偏移值信息获取资源偏移值,并根据基站指示的用于传输UCI的PUCCH的频域资源索引,确定PUCCH资源。
需要说明的是,本发明实施例中所描述的n
RU也为基站指示的用于传输UCI的PUCCH的频域资源索引。其中,上述n
RU的含义和上述实现方式中包含的n
RU的含义一致,具体可参见上述实现方式中描述的含义,在此不再赘述。
需要说明的是,上述频域资源索引可为高层信令配置的一个资源索引集合,eNB根据UE的DCI从上述资源索引集合中动态选择一个并下发给UE。上述频域资源索引也为eNB通过高层信令下发给UE的频域资源索引。UE也可通过与eNB通信的其他方式获取上述频域资源索引,具体可根据实际应用场景确定,在此不做限制。
可选的,在一些可行的实施方式中,mini slot可采用更宽的SCS,或者DCI在多个不同载波使用不同的SCS,对应的UCI在同一个PUCCH信道反馈。例如,mini slot采用更宽的SCS后,在相同时间内,CCE index个数并不变化,但是依然存在PUCCH资源冲突的问题。因此,所述频域资源映射需要基于SCS进行分割,隐式映射的计算公式需要增加一个和SCS相关的频域偏移值,如Δ
SCS,UE可根据如下表达式11至表达式14确定PUCCH资源。上述DCI占用的OFDM符号所在的SCS信息相关的频域偏移值,如Δ'
SCS,UE可根据如下表达式19至表达式22确定PUCCH资源。
其中,上述表达式11-14中各个参数的含义可参加上述表达式1-4中相关参数的含义,在此不再赘述。其中,函数f为与Δ
SCS相关的函数表达式。
上述偏移值和函数f()相关,或者直接使用偏移值Δ
SCS。例如:
f(Δ
SCS)=Δ
SCS
上述函数f的表现形式可包括如下表达式15、表达式16、表达式17和表达式18所示的四种中的任一种,或者由如下四种表达式扩展得到的更多表现形式的表达式,在此不做限制。
类似如下公式:
f(Δ
scsl)=Δ
scsl (15)
f(Δ
scsl)=Δ
scsl-1 (16)
其中,上述表达式15表示函数f的取值可由Δ
scsl确定,上述表达式16表示函数f的取值可由Δ
scsl-1确定,上述表达式17表示函数f的取值可由Δ
scs1到Δ
scsl的累加值确定,上述表达式18表示函数f的取值可由Δ
scs1到Δ
scsl-1的累加值确定。
进一步的,上述参数l与SCS的类型对应,或者和SCS的OFDM信息对应,或者和SCS的时隙类型对应,或者与SCS所在的时序关系对应。具体可根据实际应用场景确定,在此不做限制。
同理,上述Δ'
SCS也可采用相同的描述。
其中,上述表达式19-22中各个参数的含义可参加上述表达式1-4中相关参数的含义,在此不再赘述。其中,函数f为与Δ'
SCS相关的函数表达式。
上述偏移值和函数f()相关,或者直接使用偏移值Δ'
SCS。例如:
f(Δ
SCS)=Δ'
SCS
上述函数f的表现形式可包括如下表达式23、表达式24、表达式25和表达式26所示的四种中的任一种,或者由如下四种表达式扩展得到的更多表现形式的表达式,在此不做限制。
类似如下公式:
f(Δ'
scsl)=Δ'
scsl (23)
f(Δ'
scsl)=Δ'
scsl-1 (24)
其中,上述表达式15表示函数f的取值可由Δ'
scsl确定,上述表达式16表示函数f的取值可由Δ'
scsl-1确定,上述表达式17表示函数f的取值可由Δ'
scs1到Δ'
scsl的累加值确定,上述表达式18表示函数f的取值可由Δ'
scs1到Δ'
scsl-1的累加值确定。
当然如果DCI占用的时频资源块成比例增加,上述所有偏移值也成对应比例增加。例如DCI的mini slot占据的资源块比参考的mini slot占据的资源块多了一半,则对应的偏移值也多了一半。
具体实现中,上述偏移值的配置为可以通过RRC信令通知,也可以通过DCI通知,或者采用RRC通知一个集合,DCI从集合中选择其中一个的方式配置,或者DCI使能的方式配置。具体配置方式可根据实际应用场景需求确定,在此不再赘述。
需要说明的是,通常情况下,eNB和UE都是工作在一个载波上的,但是考虑到未来网络载波中载波的带宽可能很大,比如高达400MHz。特别是针对UL发送能力受限的UE,或者下行接收能力受限的UE,UE可能只能工作在有限的子带上。因此在载波或者小区的基础上,UE的资源分配或者接收引入子带的概念。例如,可以包括如下case1至case3所描述的三种情况:
Case1:UE的DL和UL都可以工作在多个子带上
如图5所示,图5为UL频域和DL频域的一示意图。在case1所示的应用场景中,UE的UL频域包括一个或者多个子带,UE的DL频域也包括一个或者多个子带,并且UE的DL子带和UL子带包括一种或者多种映射关系。其中,上述映射关系可包括一一对应的映射关系,或者一对多的映射关系,或者多对一的映射关系。其中,上述映射关系可为预定义的映射关系,eNB可通过高层信令将上述映射关系发送给UE;或者将相关配置信息通过高层信令或者预配置方式发送给UE,UE再利用其DCI动态选择一个或者多个映射关系。
在case1所示的应用场景中,UE基于资源配置信息确定PUCCH资源之前可首先获取UL频域上的子带与DL频域上的子带之间的映射关系,并根据所映射关系确定子带资源偏移值,以根据资源配置信息和子带资源偏移值确定PUCCH资源。需要说明的是,上述子带资源偏移值用于确定UL频域上的子带内使用的资源单位的偏移,这里的资源单位可以使有限个RB,这里的偏移可以使用有限个RB。具体实现中,若上述DL频域和UL频域的子带为一一对应的映射关系,则上述子带资源偏移值可为空,资源配置信息中包括的资 源单元索引值(例如,CCE index)的计算,可以以下行band为一个集合,资源单位的index为下行子带内的所有资源单位为单位对应出的一个索引值。
此外,如果多个DL子带映射到同一个UL子带,则上述子带资源偏移值则不为空,并且上述子带资源偏移值为和DL子带相关的偏移值,用于UL子带内使用的资源单位的偏移。
Case2:UE的UL可以工作在多个子带上
如图6所示,图6为UL频域和DL频域的另一示意图。此时,DL频域可为多个子带也可不分子带,具体可根据实际应用场景确定,在此不做限制。在case1所示的应用场景中,eNB将UE的UL频域的子带信息提前配置给UE,UE再利用其DCI灵活选择其中一个。依据如下公式和资源配置信息计算UE工作的UL子带对应的PUCCH资源。UE可获取eNB发送的子带配置信息,根据子带配置信息确定其工作的UL子带。进一步的,UE可根据预定义的PUCCH资源计算方式和上述获取的资源单元偏移值,计算其所工作的UL子带对应的PUCCH资源。
如下预定义的PUCCH资源计算方式所示,计算PUCCH资源时,需要对子带对应的资源单位偏移值进行取模运算,具体被取模的数值可以是多个参数的和。
移值进行取模运算,具体被取模的数值可以是多个参数的和。
其中,上述表达式27至表达式34中各个参数的含义可参见上述表达式1至表达式26中相关参数的含义,在此不再赘述。在上述表达式27至表达式34中,上述表达式1至表达式26中相关参数的含义,在此不再赘述。在上述表达式27至表达式34中,N
subband指代一个子带内的资源单位的个数。Δ
offset是和资源单位(resource unit,RU)的数据传输方式(分布式传 输或者集中式传输)相关的变量。如果RU对应的控制信息是放置在一个资源集合中的,则Δ
offset是和资源集合对应的一个偏移值,或者是一个和DCI控制信息格式相关的偏移量,和/或是一个和PUCCH的UCI承载的信息内容相关的偏移量,或者是上述各种偏移值和或偏移量的有限组合。需要说明的是,具体实现中也可以对f(Δ
SCS)相关的计算公式进行取模运算。例如,
包括上述加上变量c的部分。总的而言,取模预算可以是上述公式中所有参数中的有限个参数的和进行取模运算,用于
的计算。
Case3:UE的DL可以工作在多个子带上
如图7所示,图7为UL频域和DL频域的另一示意图。UE的DL频域被分配成不同的子带,UE如果采用基于子带的RU,即RU index是和子带相关的编号,则不同子带的RU编号是相同的,这样UL频域中的PUCCH需要采用一个偏移量来区分不同子带的偏移值,具体方法包括:
每个子带给出一个子带资源偏移值Δ
subband1,UE可根据其工作的DL子带确定其工作的DL子带对应的子带资源偏移值作为子带资源偏移值。再结合n
RU确定其所工作的DL子带对应的PUCCH资源。UE在子带i对应的UL频域资源为:
其中,上述表达式35-38中各个参数的含义可参加上述表达式1至表达式34中相关参数的含义,在此不再赘述。其中,函数f为与N
subbandi相关的函数表达式。
上述偏移值和函数f()相关,或者直接使用偏移值N
subbandi。例如:
f(N
subbandi)=N
subbandi
上述函数f的表现形式可包括如下表达式39、表达式40、表达式41和表达式42所示的四种中的任一种,或者由如下四种表达式扩展得到的更多表现形式的表达式,在此不做限制。
类似如下公式:
f(N
subbandi)=N
subbandi (39)
f(N
subbandi)=N
subbandi-1 (40)
其中,上述i表示子带相关的序列号。
其中,上述表达式39表示函数f的取值可由N
subbandi确定,上述表达式40表示函数f的取值可由N
subbandi-1确定,上述表达式41表示函数f的取值可由N
subband1到N
subbandi的累加值确定,上述表达式42表示函数f的取值可由N
subband1到N
subbandi-1的累加值确定。
需要说明的是,上述子带相关方案可和上述其他实施例之后的方案联合使用。
这样上述计算公式为多个f()函数引入到一个公式中。可选的对此公式中的一个或者多个参数,进行基于子带的取模运算。
例如,采用如下计算公式:
上述公式的取低运算,也可以为取整,或者取余运算,相应的,与之相乘的数值也可做相应调整。具体可根据实际应用场景确定,在此不做限制。
UE根据其工作的DL子带确定子带资源偏移值,并基于资源配置信息(即资源单位偏移值,例如nCCE)确定其所工作的DL子带对应的PUCCH资源。
需要说明的是,DL频域上的子带和/或UL频域上的子带可以基于所述终端设备的UCI内容分配得到。比如,UE的HARQ反馈可以集中到一个子带反馈,CSI信息相关集中到一个子带反馈。
可选的,UE的资源单位索引值在计算时考虑其在时域上的累加。例如minislot的资源单位索引值的初始值以其时域之前的slot的最后一个单位索引值的数值+1为数值。minislot 的资源单位索引值的都需要其在本minislot内索引值加上其时域之前的slot的最后一个资源单位索引值的数值为其数值。
UE工作在一个有限的带宽上的,上述有限带宽小于载波带宽。上述子带可以为载波带宽上的子带,也可以为UE工作的有限带宽。UE在一个载波上的带宽,和子带之间是可以互相包含。
n
RU基于有限带宽计算,则也有频域偏移值,用于PUCCH资源的计算。
UE可以选择在子带上进行PUCCH跳频。基于slot的子带跳频,即每个时隙可以依据一定的规则选择对应的子带,和/或基于PUCCH控制信道类型的子带跳频,即UE在每个PUCCH控制信道选择对应的子带。选择的依据包括基于UE的ID,cell的ID,Beam的ID,slot信息,信道信息对其取模,选择合适的子带。或者依据一定的子带级别的偏移进行跳频。
n
RU可以DCI所在的资源单位的第一个索引值,或者可以为DCI所在的资源单位的第j个索引值。j为自然数,或者可以为资源单位的个数。
DCI可以为UE具体的DCI,或者可以为UE group的DCI,或者可以为Cell具体的DCI,公共搜索空间的DCI,非公共搜索空间的DCI。
需要说明的是,上述频域资源索引可为高层信令配置的一个资源索引集合,eNB根据UE的DCI从上述资源索引集合中动态选择一个并下发给UE。上述频域资源索引也为eNB通过高层信令下发给UE的频域资源索引。UE也可通过与eNB通信的其他方式获取上述频域资源索引,具体可根据实际应用场景确定,在此不做限制。
数据包为一个或者多个传输块,或者为一个或者多个码块,或者为传输块和码块的组合。或者码块从属于和它一起发送的传输块,多个码块来自一个传输块。
UE获取的资源配置信息包括频域资源索引信息,所述频域资源索引信息包括与UE的时隙类型信息,或者UE的下行共享信道数据包所在资源的时域信息和/或频域信息,或者子带信息对应的频域资源索引信息。UE基于所述频域资源索引信息确定上行控制信道资源包括:
UE根据所述频域资源索引信息,以及上行控制信道类型相关的偏移量确定上行控制信道资源。
频域资源索引信息可以为与UE的时隙类型信息对应的频域资源索引信息。频域资源索引信息可以为与UE的下行共享信道数据包所在资源的时域信息和/或频域信息对应的频域资源索引信息。频域资源索引信息可以为与子带信息对应的频域资源索引信息。频域资源索引信息可以为与下行控制信息DCI所在资源的时域信息和/或频域信息对应的频域资源索引信息。频域资源索引信息可以为与UE的时隙类型信息,或者UE的下行共享信道数据包所在资源的时域信息和/或频域信息,或者子带信息对应的频域资源索引信息至少之一对应的频域资源索引信息。通过将频域资源索引信息与具体的UE的时隙类型信息信息对应,则slot与minislot对应的下行信息的上行UCI反馈在不同的频域资源上,避免其发送在同一资源上,引入冲突。
需要说明的是,n
RU或者n
RU,q可以为上述频域资源索引。上述频域资源索引可为高层信令配置的一个资源索引集合,接入网设备从上述资源索引集合中选择一个通过下行控制信息发送给终端设备。上述频域资源索引也为接入网设备通过高层信令下发给终端设备的频域资源索引。上述频域资源索引也为接入网设备通过下行控制信息发给终端设备的频域资源索引。终端设备也可通过与接入网设备通信的其他方式获取上述频域资源索引,具体可根据实际应用场景确定,在此不做限制。下行控制信息包括第一DCI(设为DCI1),或者第二DCI,或者第一DCI(设为DCI1)和第二DCI(设为DCI2)共同承载。
在一些可行的实施方式中,上述资源配置信息包括码分复用信息。上述码分信息包括DCI占用的正交频分复用技术OFDM符号信息对应的码分复用资源,或者UE的时隙类型对应的码分复用资源。上述码分复用资源可以包括承载UCI信息的参考信号序列信息,序列的循环偏移信息,用于时域和或频域正交序列信息。
UE可根据上述码分复用信息确定PUCCH的发送方式。
利用码分复用方式,可以让来自不同时隙的,或者原本频域冲突的两个UCI使用相同的时域资源和/或频域资源,但是两个UCI彼此通过码分复用的方式保持正交性。上述码分可以用在空分的方式上。或者是其中一个类型的码分复用信息或者码分复用信息对应的索引值,进行了偏移等。
具体实现中,上述资源配置信息包括DCI占用的OFDM符号信息对应的码分复用信息,或者DCI占用的子载波间隔(subcarrier spacing,SCS)信息对应的码分复用信息,或者DCI占用的OFDM符号所在的SCS信息对应的码分复用信息。UE可根据上述任一表现形式的码分复用信息确定用于传输UCI的PUCCH资源。具体实现中,上述DCI占用的OFDM符号信息对应的码分复用信息具体可为DCI占用的每个或者指定个数的下行OFDM符号对应的码分复用信息。例如,在如图2所示的传输模式中,UE的DCI占用了子载波1中的slot0包括的OFDM符号,其中,可预先配置slot0中的前2个OFDM符号对应一个Nl(例如Nl1),slot0中的mini slot包括的2个OFDM符号对应一个Nl(例如Nl2)。其中,上述Nl1或者Nl2则为上述下行OFDM符号对应的码分复用信息的资源偏移值。Nl1或者Nl2为2个OFDM符号对应的码分复用信息的资源偏移值等。具体实现中,也可配置每个OFDM 符号对应一个PUCCH资源偏移值,即每个OFDM符号对应一个Nl。
DCI占用的OFDM符号信息也可以为DCI占用的时隙类型对应的码分复用信息。具体实现中,上述DCI占用的时隙类型对应的码分复用信息具体可为DCI占用的每个时隙类型对应的码分复用信息。例如,在如图2所示的传输模式中,UE的DCI占用了子载波1中的slot0中的资源,利用slot0的资源发送数据包,对应一个Nl(例如Nl1),slot0中的mini slot包括的2个OFDM符号对应一个Nl(例如Nl2)。其中,上述Nl1和Nl2则为上述DCI占用的2个时隙类型对应的码分复用信息的资源偏移值。Nl1或者Nl2为2个时隙类型对应的码分复用信息的资源偏移值。可选的,上述Nl1和Nl2对应的2个时隙类型的可以相同,或者不同。可选的,上述Nl1和Nl2对应的2个时隙类型占据不同的时域和/或频域资源。可选的,上述Nl1和Nl2对应的2个时隙类型可以对应的时域资源可以交叠或者不交叠。可选的,上述Nl1和Nl2对应的2个时隙类型,可以占据相同的时隙,或者不同的时隙。上述时隙类型以及各个时隙类型占用的资源情况可以是上述各种可选方案的组合,具体可根据实际应用场景需求确定,在此不做限制。

在一些可行的实施方式中,UE接收eNB发送的PDSCH域的数据包,因为UE处理能力有限,如果eNB希望能够UE尽快将UCI发送给eNB,则需要和UE之间进行有效的定时约束。eNB发送的或者预配置的PUCCH资源配置信息包括可通过隐式映射的方式通知UE,也可通过显示的方式告知UE,具体可根据实际应用场景确定,在此不做限制。
隐式映射的方式通知UE时,上述资源配置信息中可包括查找PUCCH的指示信息。例如,在DCI中用1bit的信息指示当前传输块(transport block,TB)反馈UCI使用距离当前时刻最近的PUCCH传输UCI,上述PUCCH可为long PUCCH或者short PUCCH,具体不限定,或者通过其他方式通知UE,在此不做限制。UE根据指示信息查找距离当前时刻最近,并且在当前时刻之后的满足信道需求的PUCCH资源,将查找到的PUCCH资源确定为用以传输UCI的PUCCH资源。
其中,上述当前时刻为UE接收到eNB下发的DCI的时刻,或者UE解析得到PDSCH数据包的时刻,在此不做限制。
此外,在一些可行的实施方式中,隐式映射的方式通知UE时,上述资源配置信息中可包括PUCCH的信道类型,上述PUCCH的信道类型包括shortPUCCH和/或longPUCCH,和/或者一种具体PUCCH格式的信道,或者上述一种或者多个信道类型的组合,在此不做限制。例如,在DCI中用1bit的信息指示当前传输块(transport block,TB)或者CB(码块)反馈UCI使用距离当前时刻最近的PUCCH传输UCI,上述PUCCH可为long PUCCH或者short PUCCH,具体可根据上述资源配置信息中携带的信道类型指示确定。UE根据指示信息查找距离当前时刻最近,并且在当前时刻之后的满足信道类型需求的PUCCH资源,将查找到的PUCCH资源确定为用以传输UCI的PUCCH资源。
需要说明的是,上述当前时刻的单位可以为子帧、时隙和或时隙中的有限个OFDM符号。
进一步的,在一些可行的实施方式中,UE的DCI中可使用x个bits指示使用第k个 后续的PUCCH传输UCI。其中,上述后续的第k个PUCCH可为任一信道类型的PUCCH,也可为后续的第k个long PUCCH,也可为后续的第k个short PUCCH,也可为后续的第k1个long PUCCH和第k2个short PUCCH。其中,k1和k2均小于k。
具体实现中,上述资源配置信息包括PUCCH的比特信息,UE可根据上述比特信息查找当前时刻之后的第k个short PUCCH和/或long PUCCH,将查找到的short PUCCH和/或long PUCCH确定为用以传输UCI的PUCCH。进一步的,UE也可根据上述比特信息,从当前时刻起始的PUCCH开始查找,将从起始的PUCCH的PUCCH算起的第k个short PUCCH和/或long PUCCH,将查找到的short PUCCH和/或long PUCCH确定为用以传输UCI的PUCCH。上述第k个PUCCH的确定方式可根据实际应用场景确定,在此不做限制。
在一些可行的实施方式中,若eNB和UE上承载着增强移动宽带(enhanced mobile broadband,eMBB)业务,eMBB业务包括超高清视频业务、增强现实(augmented reality,AR)业务、虚拟现实(virtual reality,VR)业务等等,则由于eMBB业务的主要特点包括传输数据量大、传输速率高等特点,eNB和UE之间的数据传输速率较高,即数据接收和数据反馈的速率也将更高。eNB向UE发送PDSCH数据包,UE接收eNB发送的数据包会对应产生一个HARQ进程,此时,UE接收到数据包的时域位置即为该HARQ进程对应的时域位置。UE接收到数据包之后,还可在相应的PUCCH的时域位置上反馈该数据包的UCI信息。UE可根据eNB下发的资源配置信息或者预配置的资源配置信息确定反馈数据包的UCI的PUCCH的时域位置,进而可在确定的时域位置上反馈该数据包的UCI。
在一些可行的实施方式中,eNB可通过向UE发送资源配置信息,将用于确定PUCCH的时域位置的相关信息携带在资源配置信息中下发给UE,触发UE根据上述相关信息和接收PDSCH数据包的时域位置等信息确定反馈PDSCH数据包的UCI的时域位置。eNB也可通过高层信令触发UE根据预配置的资源配置信息中携带的相关信息,以及接收PDSCH数据包的时域位置等信息确定反馈PDSCH数据包的UCI的时域位置。具体实现中,当上述资源配置信息中携带的用于确定PUCCH的时域位置的相关信息不同时,UE确定反馈PDSCH数据包的UCI的时域位置则可能不同,具体可包括如下方式一至方式三:
方式一:
上述资源配置信息包括第一HARQ进程接收到数据包的时域位置和反馈改数据包的UCI信息的PUCCH的时域位置的定时信息。其中,上述第一HARQ可为某一个参考HARQ进程,第一HARQ进程接收到的数据包可设为数据包A(或者第一数据包)。第一HARQ进程接收到的数据包A的时域位置与反馈数据包A的UCI的PUCCH的时域位置之间存在一个定时信息,该定时信息可为子帧间隔、时隙间隔,或者OFDM符号间隔中的至少一种,在此不做限制。
这里,子帧间隔,时隙间隔,或者OFDM符号间隔中的至少一种,具体包括OFDM符号间隔,或者子帧间隔和时隙间隔,或者子帧间隔、时隙间隔和OFDM符号间隔,或者时隙间隔和OFDM符号间隔,或者子帧间隔和OFDM符号间隔。
具体实现中,UE获取得到上述资源配置信息中携带的定时信息之后,当UE接收到数据包B(设为第二数据包)时,UE则可根据上述定时信息和HARQ进程(设为第二HARQ进程)接收到的数据包B的时域位置等信息确定反馈数据包B的UCI的PUCCH的时域位 置。具体的,UE接收到数据包A的时域位置和接收到数据包B的时域位置均为UE可知的信息,UE可根据第一HARQ进程接收到数据包A的时域位置(设为第一时域位置)和上述定时信息确定反馈数据包A的UCI的PUCCH的时域位置。进一步的,UE可将第一HARQ进程和第二HARQ进程接收到数据包的时域位置的差值作为反馈数据包A的UCI的PUCCH的时域位置与反馈数据包B的UCI的PUCCH的时域位置的差值。UE确定了反馈数据包A的UCI的PUCCH的时域位置之后,则可根据上述差值确定反馈数据包B的UCI的PUCCH的时域位置。
在方式一所描述的实现方式中,UE将参考HARQ进程接收到数据包的时域位置与反馈该数据包的UCI的PUCCH的时域位置的定时信息(设为第一定时信息)作为参照定时关系,上述参考定时关系可为后续HARQ进程接收到新的数据包的时域位置与反馈新的数据包的UCI的PUCCH的时域位置之间的定时信息(设为第二定时信息),如,第二定时信息与第一定时信息相同等。
方式二:
上述资源配置信息包括接收PDSCH数据包的时域位置与PDSCH数据包的UCI反馈的PUCCH时域位置的参考定时关系。其中,上述参考定时关系用于指示HARQ进程接收下行共享信道数据包(如PDSCH数据包)的时域位置对应的反馈下行共享信道数据包的UCI的上行控制信道(如PUCCH)的时域位置。
需要说明的是,上述参考定时关系为指定HARQ进程接收到下行共享信道数据包的时域位置与反馈下行共享信道数据包的UCI的上行控制信道的时域位置的时域位置关系。上述指定HARQ进程为预配置的或者接入网设备发送的HARQ标识ID所指示的HARQ进程。
上述参考定时关系可用于任一HARQ进程,即每个HARQ进程接收到数据包的时域位置与反馈该数据包的UCI的PUCCH的时域位置的差值均相同。
具体实现中,UE获取得到上述资源配置信息之后,当UE接收到新的数据包时,UE则可根据接收到新的数据包的时域位置和所述参考定时关系,确定反馈该新的数据包的UCI的PUCCH的时域位置。
参考定时关系可为子帧间隔、时隙间隔,或者OFDM符号间隔中的至少一种,在此不做限制。
这里,子帧间隔,时隙间隔,或者OFDM符号间隔中的至少一种,具体包括OFDM符号间隔,或者子帧间隔和时隙间隔,或者子帧间隔、时隙间隔和OFDM符号间隔,或者时隙间隔和OFDM符号间隔,或者子帧间隔和OFDM符号间隔。
方式三:
上述资源配置信息包括接收PDSCH数据包的时域位置与PDSCH数据包的HARQ反馈的PUCCH时域位置的参考定时关系。此外,上述资源配置信息还包括预配置的时域位置偏移值。与上述方式二相同,上述参考定时关系用于指示HARQ进程接收到下行共享信道数据包的时域位置对应的反馈下行共享信道数据包的UCI的上行控制信道的时域位置。
需要说明的是,上述参考定时关系为指定HARQ进程接收到下行共享信道数据包的时域位置与反馈下行共享信道数据包的UCI的上行控制信道的时域位置的时域位置关系。上 述指定HARQ进程为预配置的或者接入网设备发送的HARQ标识ID所指示的HARQ进程。
上述参考定时关系可用于任一HARQ进程。进一步的,在方式三所描述的实现方式中,当UE接收到新的数据包时,UE接收到新的数据包的HARQ进程的时域位置与反馈该数据包的UCI的PUCCH的时域位置的差值则为上述参考定时关系所指示的差值和上述时域位置偏移值之和。所述时域位置偏移值可通过高层信令配置的一个时域位置偏移值的索引集合,eNB根据UE的DCI从上述索引集合中动态选择一个并下发给UE。上述时域位置偏移值也为eNB通过高层信令下发给UE的时域位置偏移值。UE也可通过与eNB通信的其他方式获取上述时域位置偏移值,具体可根据实际应用场景确定,在此不做限制。
具体实现中,UE获取得到上述资源配置信息,则可根据上述参考定时关系和时域位置偏移值确定接收数据包的HARQ进程的时域位置与反馈数据包的UCI的PUCCH的时域位置的差值。进一步的,当UE接收到新的数据包时,UE则可根据接收到新的数据包的时域位置和上述确定的差值,确定反馈该新的数据包的UCI的PUCCH的时域位置。
进一步的,在一些可行的实施方式中,上述资源配置信息中包括的信息也可为HARQ标识(identity,ID)等信息,UCI的PUCCH的时域位置与HARQ ID关联,进而可通过上述HARQ ID指示UCI的PUCCH的时域位置。UE可将资源配置信息中携带的HARQ ID所指示的HARQ的PUCCH的时域位置确定为用以传输UCI的PUCCH资源。例如,若一个slot(例如slot0)的eMBB业务中存在一个突发mini slot的低时延高可靠通信(ultrareliable and low latency communications,URLLC)业务,则可通过资源配置信息指示mini slot对应的HARQ进程(设为HARQ进程1)可与slot0对应的HARQ进程(设为HARQ进程2)采用相同的PUCCH的时域位置。此时,上述资源配置信息中可携带HARQ进程2的HARQ ID,以触发UE在HARQ进程2对应的PUCCH的时域位置传输UCI。
上述资源配置信息也可在HARQ进程2的DCI信息中携带,在此不做限制。
本发明的时域位置偏移值,包括基于时隙的偏移值,基于OFDM符号的偏移值,基于子帧的偏移值的之一或者组合。
本发明实施例中的时隙或子帧内的时域位置信息,可进一步包括如下情况之一:时隙和时隙内OFDM符号的时域位置信息,子帧和子帧内OFDM符号的时域位置信息,子帧内的OFDM符号的时域位置信息,时隙内的OFDM符号的时域位置信息,子帧,子帧内时隙,以及时隙内的OFDM符号的时域位置信息。还包括如下情况之一:时隙的时域位置信息,子帧的时域位置信息,子帧和时隙的时域位置信息。
实现方式三:
在一些可行的实施方式中,UE获取上行控制信道的资源配置信息之后,也可基于上述资源配置信息确定上行控制信道所在的时隙或子帧内的时域位置信息。具体的,考虑到UE的每个slot的类型,eNB是提前通知UE的,即每个slot上有多少个UL OFDM符号UE是提前知道的,因此将所有长度为L的PUCCH可能存在的位置通过bit信息表示。Bit的数值表示一种可能存在的情况,PUCCH的长度信息采用另外的信令发送给UE,或者将长度为L也纳入bit信息表示范围。例如UL占据多数的如下子帧类型:长度为2个OFDM符号(ofdm symbol, os)的short PUCCH在时隙slot0中有3个可选位置,可以编码为2bit表示。长度4个os的long PUCCH在slot1中有2个可选位置,可以编码为1bit表示。例如,参见图8,是本发明实施例提供的OFDM符号示意图。如图8所示,假设,slot0的7个os中,UD占据的os为4个(灰色部分),其中,长度为2个os的位置有3个可选位置。例如图8中的slot0的4个灰色标记的os中的前面2个,中间2个或者最后2个等。Slot1的7个os中,UD占据的os为5个(灰色部分),其中,长度为4个os的位置有2个可选位置。例如图8中的slot1的5个灰色标记的os中的前面4个,或者后面4个等。进一步的,也可在1个slot内,不同长度的PUCCH的位置形成一个PUCCH位置集合,用bits表示集合中每种情况的编码。即,上述PUCCH位置集合中包括多个PUCCH位置元素,每个PUCCH位置元素指代一个PUCCH的时域位置和/或频域位置。每个PUCCH位置元素指代的PUCCH的时域位置可包括short PUCCH的时域位置或者long PUCCH的时域位置。例如,在一个slot中,长度为2个os的PUCCH共有3个位置,长度为1个os的PUCCH共有4个位置,长度为4个os的PUCCH共有1个位置,共计8个位置,可用3bit表示一个PUCCH位置集合。上述PUCCH位置集合中包括8个元素,每个元素指代一个PUCCH位置。例如,000可表示表示长度为L的PUCCH在一个slot中的具体位置,例如在slot0中的第一个OFDM符号等。
UE获取得到上述资源配置信息中包括的比特指示信息之后,则可根据比特指示信息从上述预定义的或者预先配置的PUCCH位置集合中查找上述比特指示信息所指示的PUCCH的时域位置和/或频域位置,将查找得到的PUCCH的时域位置和/或频域位置确定为用以传输UCI的PUCCH资源。
在上述实现方式中,eNB利用bit信息指示一个slot中存在的各种长度的PUCCH所在的时域位置,并通过一个PUCCH位置集合表示,减少了PUCCH资源位置配置时所使用的DCI数据,提高了DCI数据的有效利用率。
在上述实现方式中,eNB利用bit信息指示一个slot中存在的各种长度的PUCCH所在的频域位置,并通过一个PUCCH位置集合表示。减少了PUCCH资源位置配置时所使用的DCI数据,提高了DCI数据的有效利用率。
在上述实现方式中,eNB利用bit信息指示一个slot中存在的各种长度的PUCCH所在的时域位置和频域位置,并通过一个PUCCH位置集合表示。减少了PUCCH资源位置配置时所使用的DCI数据,提高了DCI数据的有效利用率。
上述bit指示信息,可以通过高层信令发送给UE,或者通过DCI发送给UE。或者通过高层信令发送一个集合,DCI从中集合选择一个或者若干元素的方式发送给UE。本发明实施例中的高层信令包括无线资源控制(radio resource control,RRC),介质访问控制(media access control,MAC),广播或者系统信息中的至少一种。
在一些可行的实施方式中,若5G通信系统支持PUCCH和PUSCH同时发送,则可在上述资源配置信息中携带PUCCH在PUSCH资源上占据的资源信息,并下发给UE。上述资源信息用于指示UE在PUSCH资源的频域的一端或者两端的指定个数的OFDM符号上发送UCI;或者用于指示UE在PUSCH资源的频域的一端或者两端的全部OFDM符号上发送UCI。
需要说明的是,上述PUSCH资源的频域的一端或者两端的频域资源为预配置的频域 资源,或者eNB指定的频域资源,或者根据UE DL DCI或者数据包信息获取的信息与偏移值而获取的频域资源。可以在PUSCH资源的最边缘的频域区域,或者和边缘频域区域有一定的空隙。上述指定个数的OFDM符号可为有限个的OFDM符号,上述有限个OFDM符号可在频域的一端或者两端;进一步的,上述有限个的OFDM符号也可为全部OFDM符号,具体可根据实际应用场景需求配置,在此不做限制。配置方式可包括通过高层信令配置,或者通过DCI指示,或者通过高层信令和DCI指示结合的方式配置等。
进一步的,也可以配置PUCCH format在PUSCH资源内的重复次数,重复次数可根据实际应用场景需求确定。重复发送的具体位置包括时域重复的具体位置,和/或包括频域重复的具体位置。
上述有限个OFDM符号与PUSCH的OFDM符号个数不一定为PUSCH符号个数的一半,OFDM符号关系和PUCCH的具体发送类型和/或格式相关。
进一步的,在一些可行的实施方式中,PUCCH也可在PUSCH资源的区域外,具体的频域和时域的偏移值可以由配置信息决定。或者PUSCH资源以PUCCH资源为基础进行偏移,具体的频域和时域的偏移值可以由配置信息决定,实现方式更加灵活,使得PUCCH,PUSCH可以根据实际使用时UE的上行发送数据的带宽能力,以及PUCCH,PUSCH信道的干扰情况,灵活选择对应的发送资源,适用性更高。
在本发明实施例中,PUCCH的资源配置信息可通过多种方式下发给UE,UE可根据资源配置信息中携带的信息确定发送UCI的PUCCH的时域位置和/或频域位置,操作更灵活,适用性更强。
