所述的接收波束是指,无需指示的接收端的波束,或者发送端可以通过当前参考信号和天线端口与UE反馈报告的参考信号(或基准参考信号)和天线端口的准共址(QCL)指示下的接收端的波束资源。
在一实施例中,在波束指示中,原参考信号是指之前曾经测量的参考信号,作为参考源;而目标参考信号,是指该信道特征需要指示的参考信号,用于确定所关联参考信号的信道特征加载。
所述的准共址(QCL)涉及的参数至少包括,多普勒扩展,多普勒平移,时延拓展,平均时延,平均增益,空间参数,空间关系和空间接收参数。
链路重配置请求也称为,波束恢复请求。
本申请提出了一种参考信号信道特征配置方法,所述方法包括:步骤100和步骤200。
在步骤100中,基站配置M个第一类集合,其中第i个集合内部包含Ni个索引元素。
在步骤200中,基站向UE发送信令,信令中携带有配置的M个第一类集合。
其中,配置的M个第一类集合中,其中第i个集合内部包含Ni个索引元素,并且将配置信息告知给UE端。其中,M和Ni是大于等于1的整数。在仅考虑单beam的情况下,第一类集合下的每一个集合内的索引元素的数目可以都仅为1个。所述的第一类集合,可以称为传输控制指示(transmission configuration indication),或者备选的传输控制指示(candidate transmission configuration indication),或者上行的传输控制指示。
例如,在每个集合下索引元素都为1时,我们有第一类集合,即备选的传输控制指示状态,如表1所示。
表1、备选的传输控制指示状态实例一
状态序号 参考信号索引
0 CRI-1
1 CRI-8
N-1 SS block-8
在一般案例下,配选的传输控制指示状态,如表2所示。其中,每个状态可以关联大于等于1个参考信号索引。
表2 备选的传输控制指示状态实例二
Figure PCTCN2018116115-appb-000001
其中,所述的索引可以包括如下至少之一或者组合:索引元素序号、参考信号类型索引、参考信号资源配置索引、参考信号资源集合索引、参考信号资源索引、参考信号端口索引、资源块索引、资源块突发索引、资源块突发集合索引、测量限制窗口索引、时域窗索引、报告配置索引、波束分组索引、测量约束、配置约束、时间约束、触发信息、以及参考信号分组索引。
其中,参考信号包括如下至少之一:同步信号块SS block、信道状态信息参考信号CSI-RS、信道探测参考信号SRS、物理随机接入信道信号(Physical Random Access Channel,PRACH)、以及解调参考信号DMRS。
对于非周期参考信号,例如aperiodic CSI-RS时,指示该aperiodic CSI-RS需要额外配置触发信息。对于非周期的CSI-RS而言,系统端可能会多次触发aperiodic CSI-RS,而触发信息可以用于区分具体的aperiodic CSI-RS指示。在一实施例中,存在一种索引行为是触发索引,而aperiodic CSI-RS指示模式是触发索引+CRI。
在一实施例中,所述重配置所述第一类集合包括至少如下之一:向所述第一类集合中添加集合;删除所述第一类集合中指定集合;更新所述第一类集合中指定集合内的元素;删除所述第一类集合中指定集合内的元素;添加所述第一类集合中指定集合内的元素。在一实施例中,重配置所述的第一类集合可以通过无线资源控制(Radio Resource Control,RRC)信令或者媒体接入控制-控制元素(Medium Access Control-Control Element,MAC-CE)信令实现。在一实施例中,重配置可通过一个独立的信令实现,而不仅是第一类信令。
在所述的第一类集合基础上,支持对于第一类集合的筛选,进而构成第二类集合。在一实施例中,生成第二类信令包括如下操作至少之一。
(1)激活第一类集合中的集合,构成第二类集合。
(2)组合第一类集合中的集合,构成第二类集合。
(3)组合第一类集合中集合内的元素,构成第二类集合。
向第二通信节点发送第二类信令。其中,第二类集合,共包括S个集合,第i个所述集合内部包含k i个索引元素。S和k i是大于等于1的整数。在一实施例中,参考信号信道特征配置方法包括使用比特地图,指示第一类集合中的集合或者集合中的元素来构成第二类集合。第一类集合中的集合或者集合中的元素,与比特地图中的每个比特相对应。所述的比特地图(bitmap)是指,通过一组二进制系列中的1和0元素以及元素的位置来指示所关联的信息是否有效或是否激活。
若比特位置为特定数值时,表示(I)激活/组合或者选择所关联集合;或者(II)激活、组合或者选择所关联集合中的元素。通过比特地图选择出的集合或者集合中的元素,按照比特地图中顺序依次编码,用于指示第二类集合中的集合或者集合中的元素。
例如,第一类集合下一共有16个集合,则激活第一类集合中(8个集合)的信令,可以分别显式指示:例如1,3,5,6,7,8,15,16;或者,通过比特地图来进行指示。
在一实施例中,通过16比特(bit)来分别对应于需要第一类集合中的每一个集合,1代表激活该集合,否则,0表示不激活,例如16’b1010111100000011。因此,仅需要16个比特就可以有效的指示和激活其中任意集合。在一实施例中,存在一个门限k,当需要激活的集合数目大于或者大于等于k时,使用比特地图的方法;否则,使用显式指示的方法。其中k为大于等于1的正整数。在一实施例中,
Figure PCTCN2018116115-appb-000002
其中T表示为第一类集合中集合的个数。
在一实施例中,该显式以及比特地图的方法可以扩展到对于集合中元素的指示,以及集合和集合元素的联合激活中来。
在本申请的另一个实施例中,第二类集合中的X1个集合被显式指示,而M-X1个集合使用比特地图进行指示,其中,X1是大于等于1的整数。在一实施例中,第二类集合使用两种不同的指示办法来进行指示。比特地图可以有效节省花销,但是,比特地图并不能提供有效的顺序信息。而,从第一类集合中选择中,第二类集合中其中特定位置的集合和其他集合的默认配置不一致。
在一实施例中,根据准则(包括,最低序号的集合;最高序号的集合;第 一通信节点预先指定或者配置的序号时,所述序号下的集合),则所述第二类集合中的约定集合,用于指示所关联的物理上行控制信道(Physical Uplink Control CHannel,PUCCH),或者用于指示所关联的物理上行控制信道(PUCCH)的解调参考信号的信道特性假设。
例如,第一类集合下一共有16个集合,则激活第一类集合中(8个集合)的信令,可以通过一个显式信令加一个比特地图来进行指示。例如,激活1,3,5,6,7,8,15,16,而其中6作为第二类集合中的第一个集合,则信令格式为{显式指示,比特地图}={6,16’b1010101100000011}。在一实施例中,比特地图将不指示显式指示的集合,则信令格式为{显式指示,比特地图(跳过显式指示比特)}={6,15’b101011100000011}。在一实施例中,我们将获得如下的第二类集合。
第二类集合序号 所对应的第一类集合索引
1 第一类集合-集合6
2 第一类集合-集合1
3 第一类集合-集合3
4 第一类集合-集合5
5 第一类集合-集合8
6 第一类集合-集合8
7 第一类集合-集合15
8 第一类集合-集合16
下面的实施例结合DL control,data channel,以及UL control and data channel的场景进行说明。
根据第一类集合和第二类集合构成的可选集合,通过第三类信令来进行指示。在一实施例中,第三类信令,可能是MAC-CE信令或者下行控制信息(Downlink Control Information,DCI)信令。在一实施例中,指示第二类集合中的一个集合,和指示第一类集合中的一个集合中的至少一个集合,用于如下至少之一。
(a)指示所关联的下行解调参考信号的信道特性假设。
(b)指示所关联的上行解调参考信号,或者指示所关联的上行解调参考信号的信道特性假设。
(c)指示所关联的物理上行控制信道(PUCCH),或者指示所关联的物理上行控制信道(PUCCH)的所关联的层(layer)。
(d)指示所关联的物理上行共享信道(Physical Uplink Shared Channel,PUSCH),或者指示所关联的物理上行共享信道(PUSCH)的所关联的层(layer)。
(e)指示所关联的信道状态信息参考信号(CSI-RS)的信道特性假设。
(f)指示所关联的信道探测参考信号(SRS)的信道特性假设。
(g)指示所关联的干扰测量参考信号(Interference Measurement Resource,IMR)的信道特性假设。
向第二通信节点发送第三类信令。
图1为本申请实施例提供的一种波束指示方法的示意图,应用于面向下行业务信道(Physical Downlink Shared Channel,PDSCH)和物理下行控制信道(Physical Downlink Control Channel,PDCCH)的波束指示的场景下,其中:
目标参考信号/信道:Target RS/Channel;
RRC信令:RRC signaling;
MAC-CE信令:MAC-CE signaling;
DCI信令:DCI signaling;
M备选TCI状态,其中每个状态可以关联非周期(通过触发信息和Set ID指示)/半持续/周期CSI-RS,SSB,以及非周期(通过触发信息和Set ID指示)/半持续/周期SRS:M candidate TCI states,each of which is associated with aperiodic(identified by triggered info or set ID),semi-persistent,periodic CSI-RS,SSB,aperiodic(identified by triggered info or set ID),semi-persistent,periodic SRS;
参考RS池用于至少空间QCL指示:Reference RS pool for at least spatial QCL indication;
使用1个状态指示PDCCH DMRS QCL假设:1state indicated for PDCCH DMRS QCL assumption;
使用比特地图信令来指示M个备选TCI状态:Using one bitmap signaling for M candidate TCI states;
2 Na TCI状态:2 Na states TCI;
映射2 Na TCI状态到Na bit DCI字段:Mapping 2 Na TCI states into Na bit DCI field;
指示2 Na TCI状态用于PDSCH波束指示:Indicating one of 2 Na TCI states for PDSCH beam indication。
首先,基站配置M个第一类集合,即配置一个包含M个配选的传输配置指示(Tag Control Information,TCI)状态集合。其中,每一个集合关联到非周期、半持续以及周期的CSI-RS和SSB。也就是说,每个集合管理到非周期、半持续以及周期的CSI-RS和SSB中的一个或组合,M个第一类集合携带在第一类信令中,第一类信令通过RRC发送给UE。其中,配选的TCI状态集合,也可以关联到非半持续以及周期的SRS资源。
对于PDCCH而言,可以通过MAC-CE进行指示,而对于PDSCH而言,如果M>2 Na时,启用MAC-CE信令进行选择,从M个配选TCI状态中,选择2 Na个TCI状态,并且建立2 Na和Na个比特的DCI指示字段进行关联,即第二类信令。
最后,对于PDSCH,通过DCI进行波束指示,完成第三类信令的传输。
其中,存在将PDCCH和PDSCH进行联合指示的方法,因为均涉及MAC-CE信令,而MAC-CE信令可以共享,其中被激活的第一个配选的TCI状态可以作为PDCCH的指示波束。
在一实施例中,对于PDSCH和PDCCH的波束指示,是通过对于其所关联的DMRS信号的QCL指示所实现的。即由TCI来携带参考的RS索引信息,而在最后的指示阶段,关联到所对应的PDSCH的DMRS信号上来。
图2为本申请面向非周期的CSI-RS的波束指示实施例。首先,与PDCCH和PDSCH共享一个相同的备选TCI状态集合,其中:
目标参考信号/信道:Target RS/Channel;
RRC信令:RRC signaling;
MAC-CE信令:MAC-CE signaling;
DCI信令:DCI signaling;
非周期CSI-RS:Aperiodic CSI-RS;
非周期CSI-RS资源配置:Configuration for aperiodic CSI-RS resources;
配置L个非周期CSI-RS资源集合:Configuration of L aperiodic CSI-RS resource sets;
M备选TCI状态,其中每个状态可以关联非周期(通过触发信息和Set ID指示)/半持续/周期CSI-RS,SSB,以及非周期(通过触发信息和Set ID指示) /半持续/周期SRS:M candidate TCI states,each of which is associated with aperiodic(identified by triggered info or set ID),semi-persistent,periodic CSI-RS,SSB,aperiodic(identified by triggered info or set ID),semi-persistent,periodic SRS;
激活2 Nb-1个状态表示非周期CSI-RS资源集合,其中每个集合包含Ki>1CSI-RS资源:Activating of 2 Nb-1 states representing aperiodic CSI-RS resource sets,each of which contains Ki>1 CSI-RS resources;
每个Ki资源都需要与M个备选的TCI状态,其中2 Nb-1状态,每个状态下包含K i个资源:Each of the Ki resources is associated with one of the M candidate TCI states.(2 Nb-1 states,each state contains a resource set with size of K i resources;
触发2 Nb-1个非周期CSI-RS资源集合中的一个:Triggering one of 2 Nb-1aperiodic CSI-RS resource sets。
首先,除了通过RRC信令配置的配选TCI状态外,RRC信令配置L个非周期的CSI-RS资源集合。如果L大于等于2 Nb时,激活其中的2 Nb-1个状态,其中分别关联到对应的CSI-RS资源集合上来,其中每一个资源集合包含K i个CSI-RS资源。在一实施例中,可以通过比特地图的方法,从L个非周期的CSI-RS资源集合上激活2 Nb-1个非周期CSI-RS资源。在一实施例中,比特地图中非零元素的个数可以隐式指示Nb的尺寸大小。其后,通过MAC-CE信令,将candidate TCI states和非周期的CSI-RS资源关联起来,用于支持最后的2 Nb-1的非周期CSI-RS资源集合的DCI触发。
另外,如果将第二类集合中的一个集合和指示第一类集合中的一个集合中的至少一个集合,与上行参考信号索引联合编码,指示联合编码中的一个元素,或者,指示上行参考信号索引,用于如下至少之一:
(a)指示所关联的上行解调参考信号,或者指示所关联的上行解调参考信号的信道特性假设。
(b)指示所关联的信道探测参考信号(SRS)的信道特性假设。
然后,向第二通信节点发送携带上述信息的第四类信令。
在一实施例中,所述的第四类信令的信道特征假设的约束条件,强于第三类信令的信道特征假设的约束条件。第四类信令的信道特征假设,是基于相同的空间滤波器,或者基于以下所有参数集合之一:多普勒扩展,多普勒平移,时延拓展,平均时延,平均增益和空间参数;或者,多普勒扩展,多普勒平移,时延拓展,平均时延和空间参数。而,第三类信令仅基于空间参数或者空间关 系。
在一实施例中,所述的上行参考信号,包括如下之一:信道探测参考信号SRS、物理随机接入信道信号PRACH、以及上行解调参考信号UL DMRS。
在一实施例中,第三类信令,仅限制了基本的空间特征,例如上行参考信号和下行参考信号波束之间的相关度足够(而非完全相同的空间滤波器),而第四类信令,是明确要求限制目标上行参考信号需要完全与原上行参考信号的发送模式一致,包括完全一致的空间滤波器。
与相关技术相比,本申请提供了一种参考信号信道特征配置方法,包括:确定第一类信令;所述第一类信令携带有第一类集合,所述第一类集合包括多个索引元素;向第二通信节点发送第一类信令。通过本申请的方案,基于QCL假设或者强约束指示的方法,来区分的指示上行参考信号用于波束训练或者信道状态信息获取,从而能够适应用户的移动和信道的变化的场景,减少了波束指示开销,增加了系统的灵活性。
下面的实施例结合面向非周期的SRS的场景进行说明。
如果指示所关联的(即目标参考信号)SRS为非周期SRS时,如果E>=2 Nd时,第一通信节点需要从E个SRS资源集合中选择2 Nd-1个SRS资源,与DCI指示字段关联,用于非周期SRS资源触发;如果E<2 Nd时,E个SRS资源,直接与DCI指示字段关联,用于非周期SRS资源触发。所述非周期SRS,是由E个SRS资源集合构成,其中第i个SRS资源集合下包含W i个SRS资源,其中E、Nd和W i为大于等于1的正整数。
在一实施例中,可以使用比特地图,将E个SRS资源集合中选择2 Nd-1个SRS资源集合。
与相关技术相比,本申请提供了一种参考信号信道特征配置方法,通过确定第一类信令;所述第一类信令携带有第一类集合,所述第一类集合包括多个索引元素;向第二通信节点发送第一类信令。通过本申请的方案,基于QCL假设或者强约束指示的方法,来区分的指示上行参考信号用于波束训练或者信道状态信息获取,从而能够适应用户的移动和信道的变化的场景,减少了波束指示开销,增加了系统的灵活性。
图3为本申请对于非周期的SRS的信道状态信息的配置实施例其中:
目标参考信号/信道:Target RS/Channel;
RRC信令:RRC signaling;
MAC-CE信令:MAC-CE signaling;
DCI信令:DCI signaling;
配置非周期SRS资源:Configuration for aperiodic SRS resource;
配置L d个非周期SRS资源集合:Configuration of L d aperiodic SRS resource sets;
激活2 Nd-1个状态,每个状态代表非周期SRS资源集合,其中每个状态包含K i>1SRS资源:Activating of 2 Nd-1 states representing aperiodic SRS resource sets,each of which contains K i>1 SRS resources;
参考RS和目标RS关联:Association between reference and target RSs;
每K i个资源关联到M个备选的TCI状态或者MUL个备选的UL-TCI状态(其中,2 Nd-1状态,米格状态包含一个资源集合,其中每个资源集合包含Ki个资源.):Each of the Ki resources is associated with one of the M candidate TCI or MUL candidate UL-TCI states.(2 Nd-1 states,each state contains a resource set with size of K i resources.);
触发2 Nd-1非周期SRS资源集合中的一个:Triggering one of 2 Nd-1 aperiodic SRS resource sets。
首先,RRC信令配置L d个非周期的SRS资源集合,然后通过MAC-CE信令来进行对于其中2 Nd-1个状态进行激活,其中每个SRS资源集合中包含K 1个SRS资源。然后,通过配选的TCI状态或者上行UL-TCI状态来与SRS进行关联。这里,支持两种关联方法,第一种关联方法,通过QCL或者空间关联的方法进行规范,在这种情况下,仅对上行发送波束进行较粗的约束;第二种关联方法,通过SRI或CRI进行直接约束,在这种情况下,要求目标参考信号需要完全服从指示参考信号的滤波器或者完整的信道特征要求。最后,通过DCI信令,对于aperiodic SRS资源进行触发和指示。
在一实施例中,仅当L d大于等于Nd时,才需要使用MAC-CE信令进行下选择,否则可以省略该信令。但是,对于将目标参考信号和源参考信号(即备选的TCI)进行关联时,可以通过MAC-CE信令进行关联。
其中备选的UL-TCI状态,可以被称为第三类集合,而第三类集合包括T个集合,其中第i个集合包含R i个上行参考信号索引元素,其中T和R i是大于等于1的整数。在考虑一个beam的条件下,所述第三类集合下的每一个集合内的索引元素的数目可以都为1个。
总之,对于CSI-RS、SRS或者IMR为非周期参考信号,并且所述参考信号资源或者资源集合大于等于2 G时,可以通过比特地图,将Y个所述参考信号资源或者资源集合池中选择2 G-1个资源或者资源集合;然后,再将所选择的2 G-1个资源或者资源集合中的每一个集合,与所述第三类信令指定的第二类集合中的集合,或者与所述第三类信令指定的第一类集合中的集合,进行关联。
下面的实施例结合如何解决一部分与beam reporting绑定的关系的场景进行说明。
针对第一类和第二类集合或者集合中的元素,允许其与波束报告关联,根据波束报告的结果来更新指示集合或者集合中的元素。而后,第一通信节点在接收到所述的波束报告后,向第二通信节点发送确认信令,用于指示更新生效时间,其中更新生效时间,为所述确认信令发送后的X个slot,其中X是大于等于1的整数。
与所述的第一类或者第二类集合中的一个集合或元素相关联的下行参考信号的信道特征假设进行更新;或者,激活与第一类或者第二类集合中的一个集合或元素相关联相的下行参考信号。这里,下行参考信号包括如下至少之一:CSI-RS,用于时频追踪的CSI-RS,或者TRS。
图4为本申请对于与波束报告关联的波束指示实施例。首先,基站向UE配置了波束报告配置-T,并且将波束报告配置T与TCI状态a关联。在一实施例中,波束报告的配置,可以通过测量配置进而实现。在UE进行波束报告后,基站需要向UE发送确认信令。只有在确认信令生效后,才表明TCI状态a会和波束报告中的结果关联,例如最佳RSRP的beam。考虑UE的响应的花销,该关联只有在X个slot后生效,例如X的大小为4个slot。其中X的值,可以根据UE的能力进行确定。即,在X个slot后,如果基站进一步指示TCI-a,则与该报告关联的参考信号,将会成为原参考信号,用于波束指示。
在一实施例中,因为UE上报存在一定的失败的可能,如果没有基站的确认信令,很可能出现双方的误判。例如,UE认为该信息已经被告知给基站,但是基站并没有收到。因此,基站的确认信令,即响应信息,将会显著提升TCI状态更新(即关联的原参考信号)的稳定性和可靠性。在一实施例中,承载确认信令的DCI,调度PDSCH;或者,UE不希望承载确认信令的DCI不关联或者不调度PDSCH。
下面的实施例结合port index指示方法的场景进行说明。
图5为本申请端口指示以实现CSI上报的实施例。基站指示终端根据一组port index的指示测量上报CSI,其中UE对port index指示的理解满足一定的特性,例如层间嵌套的特性,例如定义这样的规则:UE用于测量rank i的port组是rank j的port组的一个子集,i<j,如图5所述,这样信令只需要通知rank 8的端口顺序就可以了。
在一实施例中,第一通信节点(基站)指示第二通信节点(UE)根据一组port index的指示测量上报CSI,其中UE对port index指示的理解满足特性要求。在一实施例中,所述的特性要求包括层间嵌套的特性。在一实施例中,所述的层间嵌套特性为用于测量rank i的port组是rank j的port组的一个子集,i<j,其中i和j为大于等于1的整数。
综上所述,基于本申请实施例提供的技术方案,建立多层的波束指示架构和使用比特地图的方法,通过创建索引集合,激活部分索引集合(和指示特定的索引集合),实现对于下行数据信道、下行控制信道、下行参考信号、上行控制信道、上行数据信道和上行参考信号的波束指示。其中,对于上行参考信号指示上,提出了两种不同约束强度的指示方法,即基于QCL假设或者强约束指示的方法,来区分的指示上行参考信号用于波束训练或者信道状态信息获取。
基于与上述实施例相同或相似的构思,本申请实施例还提供一种参考信号信道特征配置方法,应用于第二通信节点,所述方法包括:
