Abstract

本公开实施例提供一种控制信道检测、信息元素传输方法、装置、设备及存储介质,可根据信令信息和/或预设规则,确定H个第一类控制信道元素中包括的控制信道信息是否相同,其中,H为大于或者等于2的正整数;以及根据确定的结果监测控制信道。

Description

控制信道检测、信息元素传输方法、装置、设备及存储介质 技术领域
本公开涉及通信技术领域。
背景技术
NR(New Radio,新一代无线通信)中PDCCH(Physical Downlink Control Channel,物理下行控制信道)的传输配置相对LTE(Long Term Evolution,长期演进)更加灵活。
在NR中引入了CORESET(Control Resource Set,控制信道资源集合)和控制信道搜索空间集合;其中,一个控制信道搜索空间集合中的配置信息中会进一步配置聚合度分别为{1,2,4,8,16}的搜索空间包括的候选控制信道个数。每个搜索空间对应一个聚合度,一个聚合度包括的候选控制信道的个数可以为{0,1,2,3,4,5,6,8}中的一个值。一个搜索空间集合关联一个CORESET,一个CC(Component Carrier,组成载波)中最多可以配置3个CORESET,一个BWP(Bandwidth part,部分带宽)中最多可以配置10个搜索空间集合。
在相关技术中,在以波束发送PDCCH的时候,PDCCH只能达到部分覆盖,因此如何提高PDCCH的鲁棒性是目前急需解决的问题。
另外,类似地,相关技术中PDSCH(Physical Downlink Shared Channel,物理下行共享信道)只关联一个准共址参考信号集合,即只支持单波束传输,因此,如何支持多波束PDSCH的传输也是一个急需解决的问题。

下述示例中,一个控制信道可为一个PDCCH,一个PDCCH中包括一个或者多个DCI。
在一种示例中,每个CORESET中可以配置一个序列参数,用于如下序列的产生:所述CORESET中的DCI信道编码后的比特的加扰序列,所述CORESET中的控制信道解调参考信号的序列。每个CORESET中可以配置一个准共址参考信号集合,所述CORESET中的解调参考信号和所述准共址参考信号集合中的参考信号关于一类准共址参数满足准共址关系。
在一种示例中,为了增加PDCCH的鲁棒性和/或增加PDCCH的传输覆盖距离,可以通过多个候选控制信道重复发送同一个控制信息。特别是在高频通信下,为了进一步增加PDCCH的鲁棒性,优选地多个候选控制信道可采用不同的空域资源,如图5所述,重复发送的多个候选控制信道是不同的TRP(Transmission Reception Point,传输接收点,图5中为TRP0和TRP1)发送的,为此可以采用但不限于如下示例方案中的一种或者多种实现。
方案1:如图6所示为一个控制信道解调参考信号端口配置 多于一套的第二信息,第二信息包括如下至少之一:准共址参考信号集合(如图6中的Quasi-Co-Location,QCL),相位跟踪参考信号集合(如图6中的Phase Tracking Reference Signal,PTRS),序列参数(如图6中的Scraming)。其中,序列参数包括如下序列参数用于产生如下序列至少之一:控制信道信道编码后比特的加扰序列,控制信道的解调参考信号序列,控制信道的信道编码时循环移位校验位的加扰序列。如图6所示,一个解调参考信号不同套第二信息,对应候选控制信道的不同传输,图6中所述多套第二信息分别对应一个空域通道,每个空域通道可以看做分别对应一个时域和/或频域栅格,一个候选控制信道时频资源在所述多个空域通道中可以看做多个候选控制信道,一个控制信息在所述多个空域通道中重复传输或者一个控制信息在所述多个候选控制信道中重复传输,其中所述多个候选控制信道占有的时频资源的交集非空,和/或所述多个候选控制信道占有的时频资源的差集为空。
在方案1中,可以在准共址参考信号集合的TCI(Transmission Configuration Information,传输配置信息)的配置中,增加PTRS和序列参数配置信息;或者,建立TCI、PTRS和序列参数之间的关联关系。其中,TCI用于配置目标参考信号的准共址参考信号集合,所述准共址参考信号集合中包括一个或者多个参考信号,每个参考信号关联一类准共址参数,所述目标参考信号和准共址参考信号集合中的参考信号关于所述一类准共址参数满足准共址关系。如表1所示,TCI1中配置了CSI-RS1和CSI-RS2,且CSI-RS1关联的准共址参数为{多普勒频移,多普勒扩展,平均延迟,延迟扩展},CSI-RS2关联的准共址参数为空间接收参数。当DMRS1的准共址参考信号集合配置信息配置为TCI1时,表示DMRS1和CSI-RS1之间关于{多普勒频移,多普勒扩展,平均延迟,延迟扩展}满足准共址关系,DMRS1和CSI-RS2之间关于{空间接收参数} 满足准共址关系。并且一个TCI中还会配置PTRS参数和序列加扰参数,表1中一个DMRS端口关联多于一个的TCI,当然也可以是所述多于一个的TCIstate放到一个更大TCI state中,比如TCI3={TCI1,TCI2},直接配置DMRS1的准共址参数配置为TCI3。根据本公开提供的实施例,此方案也可以用于PDSCH的重复传输中,即一个PDSCH的DMRS关联多套{TCI,PTRS,信道加扰序列参数}对应多个空域通道,所述DMRS对应的PDSCH信息在所述多个空域通道上重复传输。

方案2:如图7所示在CORESET/SSS(Search Space Set)/SS(Search Space)中配置多于一个的正交解调参考信号端口,多个正交解调参考信号端口采用传输分集的方式传输同一个PDCCH;或者,多个正交解调参考信号端口分别对应的一个时频栅格,分别包括一个控制信息的一次传输,所述一个控制信息在所述多个正交解调参考信号端口对应时频栅格中重复传输。类似地,可以在CORESET/SSS/SS中配置一个解调参考信号端口,多于一个的序列参数,对应多个伪正交端口,一个控制信息在所述多个伪正交端口上重复传输。
方案3:建立多个CORESET/SSS/SS中包括的候选控制信道之间的对应关系,多个CORESET/SSS/SS中的存在对应关系的候选控制信道中包括相同的控制信息。
如图8所示,一个SSS/SS(即所述第三控制信道元素)关联多个CORESET(即所述第四控制信道元素);根据本公开提供的实施例,不同CORESET对应不同的TRP,图8中SSS1/SS1在CORESET1和CORESET2中包括的候选信道个数相同,一个简单的方法是规定SSS1/SS1分别在CORESET1和CORESET2中具有相同聚合度且在该聚合度下的候选控制信道索引相同的两个候选控制信道中包括相同的控制信息。其中,一个聚合度搜索空间中,候选控制信道的索引即公式(1)中的

上述是CORESET1和CORESET2中的关联相同SSS1/SS1的相同候选控制信道索引的候选控制信道建立关联,存在关联关系的候选控制信道中包括相同的传输信息。上述方式中,是两个TRP采用相同的聚合度传输同一个候选控制信道。即一个SS的属于不 同CORESET的候选控制信道之间满足一一对应的关系,如图9所示。
另一种方案中是组成一个SSS/SS/CORESET组(即一个第四控制信道元素组),不同组中的SSS/SS/CORESET中包括的候选控制信道中包括相同的控制信息,相同组中的SSS/SS/CORESET中包括的候选控制信道中不包括相同的控制信息;或者,相同组中的SSS/SS/CORESET中包括的候选控制信道中包括相同的控制信息,不同组中的SSS/SS/CORESET中包括的候选控制信道中不包括相同的控制信息。根据本公开提供的实施例,由于一个SSS/SS/CORESET中会包括多个候选控制信道,如果仅说两个SSS/SS/CORESET中包括的候选控制信道中包括相同的控制信息,终端的盲检复杂度就很大,如图10所示,两个CORESET中分别包括4个候选控制信道,CORESET1中的一个候选控制信道,在CORESET2中可能存在4个候选控制信道与其传输相同的控制信息,那终端的盲检复杂度就是4*4=16,即总共需要16次盲检,为了降低盲检复杂度,可以进一步约束,两个候选控制信道关联的第一类参数满足第一类约定条件时,所述两个候选控制信道中包括相同的控制信息。其中所述第一类约定条件包括如下至少之一:所述两个候选控制信道的参数取值相同;所述两个候选控制信道的参数取值的差值满足第四类约定条件,其中所述第四类约定条件包括:差值等于预定值,差值属于预定范围,差值的最小间隔大于预定值;所述两个候选控制信道的参数取值组合属于预定集合;所述两个候选控制信道的参数取值不同;所述两个候选控制信道的参数取值的交集满足第五类约定条件,其中所述第五类约定条件包括如下之一:交集为空,交集为非空,交集中包括的元素个数不小于预定值,交集中包括的元素个数不大于预定值;所述两个候选控制信道的参数取值的差集满足第六类约定条件,其 中所述第六类约定条件包括:差集为空,差集为非空,差集中包括的元素个数不小于预定值,差集中包括的元素个数不大于预定值。
根据本公开提供的实施例,所述第一类参数满足第一类约定条件包括如下至少之一:参数一:所述候选控制信道所在的所述控制信道元素的索引,比如两个候选控制信道所在的CORESET索引不同,所述两个候选控制信道所在的SSS和/或SS索引相同,两个候选控制信道包括的CCE/REG/REGBundle索引相同/或相差固定值;参数二:所述候选控制信道所在的所述控制信道元素中的最低索引,比如两个候选控制信道包括的起始或者最高CCE/REG/REGBundle索引相同/或相差固定值;参数三:所述候选控制信道的准共址参考信号集合,比如两个候选控制信道的准共址参考信号集合之间的差集非空,即两个候选控制信道是通过两个不同的发送波束,和/或不同的接收波束接收的;参数四:所述候选控制信道的时域资源,比如两个候选控制信道占有的时域符号的差集为空,或者两个候选控制信道占有的时域资源的最大间隔不能超过预定阈值,其中最大时间间隔表示两个候选控制信道占有的时域资源中间隔最远的两个时域符号之间的时间间隔,比如第一候选控制信道占有slotn中的时域符号{1,2},第二候选控制信道占有slotn中的时域符号{3,4},则所述两个候选控制信道之间的时间间隔为4-1=3个时域符号。或者两个候选控制信道属于相同的时间单元,所述时间单元为一个slot/一个子帧/一个帧/一个slot中的多个时域符号;参数五:所述候选控制信道的频域资源,比如两个候选控制信道占有的频域资源没有重叠,和/或两个候选控制信道占有的频域资源的频域间隔不超过频域预定值,比如两个候选控制信道在一个BWP中,或者一个CC中;参数六:所述候选控制信道的序列产生参数,其中所述序列包括如下序列 至少之一:所述控制信道信道编码后比特的加扰序列,所述控制信道的解调参考信号序列,所述控制信道的信道编码时循环校验位的加扰序列;比如两个候选控制信道序列参数相同或者不同,或者上述三个序列参数中的部分参数相同,部分参数不同;参数七:所述候选控制信道的解调参考信号,比如两个候选控制信道的解调参考信号相同,比如两个候选控制信道在两个CORESET中,希望这两个CORESET中的解调参考信号的序列参数相同;参数八:所述候选控制信道的聚合度,比如两个候选控制信道的聚合度相同,或者聚合度相差一定的范围;参数九:所述候选控制信道的组信息,所述组信息是配置在候选控制信道中,或者所述组信息是所述候选控制信道所在的控制信道元素比如:CORESET/SSS/SS/TCI Bundle所述的组索引,属于相同组的候选控制信道包括相同的控制信息;或,参数十:所述候选控制信道的服务小区索引,其中所述服务小区ID即为公式(1)中的n CI相同的候选控制信道中包括相同的控制信息,n CI不同的候选控制信道中不包括相同的控制信息。进一步地,当n CI为约定值时,两个CORESET/SSS/SS中的候选控制信道之间包括相同的控制信息,否则,两个CORESET/SSS/SS中的候选控制信道包括的控制信息之间没有关联关系,或者属于不同组的候选控制信道包括相同的控制信道信息。
如图11所示,CORESET1/SSS1/SS1中包括的候选控制信道有4个,4个候选控制信道中对应n CI=0的有两个,CORESET2/SSS2/SS2中的候选控制信道有4个,4个候选控制信道中对应n CI=0的有4个,而且CORESET1/SSS1/SS1的n CI=0的一个候选控制信道在CORESET2/SSS2/SS2中有两个和其存在对应关系,终端在盲检的时候只盲检2*2=4次。
上述多个控制信道元素中,一个控制信道元素为如下之一: 一个CORESET,一个SSS,一个SS,一个SSS/SS的一个时域机会occasion;其中一个SSS/SS的时域occasion在时域占有的时域个数在CORESET中配置,一个occasion的起始时域符号在SSS/SS中配置。
方案4:将一个CORESET/SSS/SS中包括的资源分为多个第四控制信道元素(其中一个第四控制信道元素组对应一个所述第四控制信息元素),根据本公开提供的实施例,一个候选控制信道包括的资源只属于一个第四控制信道元素。
如图12所示,一个控制信道元素为一个SSS/SS的一个时域机会(occasion)中的一个TCI Bundle(即所述准共址资源组);其中,一个SSS/SS的一个时域机会中属于一个CORESET的频域资源中包括多于一个的TCI Bundle,一个TCI Bundle组(即图12中的TCI Bundle)中包括整数倍个REGBundle size组(即图12中的REGBundle,即所述预编码资源组)。一个TCIBundle组对应一个准共址参考信号集合,不同TCI Bundle组中的准共址参考信号集合可以不同。或者不同TCI Bundle组中的关于第一类准共址参数(比如空间接收参数)的准共址参考信号相同或者满足准共址关系,不同TCI Bundle组中的关于第二类准共址参数(所述第二类准共址参数包括如下参数中的一种或者多种:多普勒频移,多普勒扩展,平均延迟,延迟扩展,平均增益)的准共址参考信号不同或者不满足准共址关系。
在图12中,一个TCI Bundle占有的时域符号个数和一个SSS/SS的时域occasion中占有的时域符号个数相同,在图13中一个TCI Bundle中占有的时域符号个数小于一个SSS/SS的时域occasion占有的时域符号个数。每个TCI Bundle关联一个TCI配置信息,一个TCI配置信息用于配置PDCCH的DMRS的准共址参考信号集合。
在图12和13中,一个候选控制信道占有的资源不能属于多于一个的TCI Bundle,一个REGBundle占有的资源不能属于多于一个的TCIBundle,一个SSS/SS/CORESET中的不同TCI Bundle占有的时域资源和/或频域资源之间的交集为空。上述TCI Bundle也可以称为准共址组,或者其他名称,本公开实施例对此不作任何限定。
图14中是一个SSS/SS的在一个slot中的两个occasion中包括的候选控制信道之间建立对应关系,存在对应关系的两个候选控制信道中包括相同的控制信息。
图15中是一个SSS/SS的在两个slot中的两个occasion中包括的候选控制信道之间建立对应关系,存在对应关系的两个候选控制信道中包括相同的控制信息。根据本公开提供的实施例,通过信令信息和/或约定规则通知哪些occasion中包括相同的控制信息,比如根据帧索引,子帧索引,slot索引,occasion索引中的一种或者多种,确定所述哪些occasin中的候选控制信道中包括相同的控制信息。
方案5:规定一个PDSCH可以被多个DCI调度,只要终端检测到所述多个DCI中的一个就可以解出所述PDSCH的传输参数。
方案6:规定一个SSS/SS/一个CORESET中在预定时间资源中包括的所有候选控制信道包括一个控制信息的重复传输。比如所述预定时间资源为一个或者多个时域occasion,或者为一个或者多个slot。
方案7:建立一个候选控制信道组,所述候选控制信道组中的任意两个或者多个候选控制信道中包括的控制信息相同。所述候选控制信道组中的每个候选控制信道关联一个第三信息,其中所述第三信息包括如下信息中的一种或者多种:搜索空间集合索引,搜索空间索引,成员载波索引,候选控制信道索引信息,搜 索空间集合时域ocassion索引,搜索空间时域ocassion索引,控制信道资源集合索引。所述候选控制信道组中至少存在两个候选控制信道的第三信息不同。
上述是以两个TRP为例讲述两个候选控制信道中包括相同的控制信息,类似地可以建立H个候选控制信道中包括相同的控制信息。根据本公开提供的实施例,上述是终端假设H个候选控制信道中包括相同的控制信息,基站实际采用了几个候选控制信道发送所述相同的控制信息,是基站的实现问题,即终端在所述H个候选控制信道中成功检测到的候选控制信道的个数可以小于H。所述成功检测到一个候选控制信道包括如下:所述候选控制信道的解调参考信号的接收性能超过预定值,通过所述候选控制信道单独译码所述控制信息,通过所述控制信息中的循环移位校验位得到所述控制信息成功收到。
根据本公开提供的实施例,H个控制信道元素包括相同的控制信道信息,包括控制信道信息第一类相同,控制信道信息第一类相同满足如下特征至少之一:H个候选控制信道中包括的信道编码前的控制信息比特相同;H个候选控制信道的信道编码时循环移位的加扰序列相同;H个候选控制信道中包括的信道编码后的控制信息比特不同;H个候选控制信道的聚合度不同;或,H个候选控制信道的信道编码后的加扰序列不同。
例如,如图16所示,基于K比特的控制信息即DCI比特,基于K比特控制信息得到P个CRC比特(循环移位校验位),然后对P个CRC比特进行加扰,然后送入信道编码器,信道编码之后的比特在调制之前进行加扰,加扰之后进行调制。如果H个候选控制信道中包括的控制信息是信道编码后的比特相同,但是加扰不同,或者H个候选控制信道的聚合度不同,信道编码后的比特就不同。那此时终端在处理这H个候选控制信道的时候,需要对 每个候选控制信道单独解调,然后解加扰,然后将这H个候选控制信道的解扰码之后的信息进行软合并,然后送到信道译码器,即H个候选控制信道在控制信道盲检计数的时候算作一次盲检。即H个候选控制信道中传输的调制符号不同,没有对应关系。
根据本公开提供的实施例,H个候选控制信道包括的控制信道信息相同,包括控制信道信息第二类相同,控制信道信息第二类相同满足如下特征至少之一:H个候选控制信道中包括的信道编码前的控制信息比特相同;H个候选控制信道的信道编码时循环移位的加扰序列相同;H个候选控制信道中包括的信道编码后的控制信息比特相同;H个候选控制信道的聚合度相同;H个候选控制信道的信道编码后的加扰序列相同;H个候选控制信道中传输的调制符号相同;或,H个候选控制信道中存在对应关系的子载波中传输的调制符号相同。终端在处理这H个候选控制信道时,可以将这多个存在对应关系的子载波当做不同的接收天线,综合解调,得到一个解调符号,进行一次解扰,也进行一次信道译码。为此H个候选控制信道在控制信道盲检计数的时候算作一次盲检;和/或H个候选控制信道中包括的存在对应关系的控制信道元素CCE在CCE计数时算作一个CCE;上述是H个候选控制信道的聚合度相同。另一种方案是候选控制信道一的聚合度是候选控制信道二的聚合度的整数倍;候选控制信道二中的一个子载波对应候选控制信道一中的一个或者多个子载波,存在对应关系的子载波中包括相同的调制符号。候选控制信道一和候选控制信道二是H个候选控制信道中的两个候选控制信道。根据本公开提供的实施例,信道编码速率匹配的时候,候选控制信道一以候选控制信道二得到信道编码后的信息比特,然后在多个子载波上放置相同的调制符号。如图17所示,候选控制信道一中的RE1和候选控制信道二中的{RE1,RE2,RE3,RE4}对应,都传输相同的 调制符号s1。
根据本公开提供的实施例,H个候选控制信道包括的控制信道信息相同,包括控制信道信息第三类相同,控制信道信息第三类相同满足如下特征至少之一:H个控制信道元素中包括的信息比特相同;H个控制信道元素中包括的指示信息不同;或,H个控制信道元素中至少存在两个控制信道元素,两个控制信道元素对应的信息比特域与指示信息的映射表格不同。
根据本公开提供的实施例,基站(例如TRP)和终端约定H个SSS/SS/CORESET/SSS ocassion/SS ocassion是重复传输,即H个SSS/SS/CORESET中传输的控制信道信息相同。
根据本公开提供的实施例,此时H个SSS/SS/CORESET/SSS ocassion/SS ocassion中存在对应关系的子载波中传输相同的控制信道调制符号。
一种可实施方式可如图18所示,H个SSS/SS/CORESET/SSS ocassion/SS ocassion中包括的子载波数/CCE数相同,CCE索引一一对应,存在对应关系的CCE中的对应子载波中包括相同的调制符号。
另一种可实施方式可如图19所示,H个SSS/SS/CORESET/SSS ocassion/SS ocassion中包括的子载波数/CCE数成倍数关系,一个SSS/SS/CORESET/SSS ocassion/SS ocassion中的一个子载波/CCE对应另一个SSS/SS/CORESET/SSS ocassion/SS ocassion的多个子载波/CCE,存在对应关系的CCE中的对应子载波中包括相同的调制符号。
也可以是多个SSS/SS/CORESET/SSS ocassion/SS ocassion中存在对应关系的RE中传输的信道编码后的比特相同,但是信道加扰不同,所以调制符号不同。比如存在对应关系的两个RE中传输的信道编码后的比特相同为{00},但是加扰不同,第一个 SSS/SS/CORESET/SSS ocassion/SS ocassion中RE的加扰序列为{01},加扰之后序列为{01};第二个SSS/SS/CORESET/SSS ocassion/SS ocassion中对应RE的加扰序列为{11},加扰之后序列为{11};所以这两个对应RE中传输的调制符号不同,但是两个SSS/SS/CORESET/SSS ocassion/SS ocassion中的RE还是存在对应关系,存在对应关系的RE中传输的信道加扰前的比特序列相同。
根据本公开提供的实施例,由于控制信道信道编码后比特的加扰序列的初始化参数根据c init=(n RNTI·2 16+n ID)mod2 31得到,其中n ID是高层配置给UE的参数n ID∈{0,1,...,1023},或者n ID是物理小区ID,但是n ID每个CORESET独立配置的,为了两个CORESET中传输的调制符号相同,就需要规定,这两个CORESET中n ID相同。
根据本公开提供的实施例,包括相同控制信道信息的H个控制信道元素占有的资源之间的最大间隔需要满足预定条件,其中资源包括时域资源和/或频域资源,这个限定主要是为了控制信道的解码延迟,以及终端的复杂度和功耗。
根据本公开提供的实施例,一个控制信道元素在频域上可包括一个或者多个的准共址资源组;和/或,一个控制信道元素在时域上包括一个或者多于的准共址资源组。
根据本公开提供的实施例,一个控制信道元素包括如下之一:一个CORESET/一个SSS/一个SS/一个SSS的一个时域occasion/一个SS的一个时域occasion。
根据信令信息或者约定规则得到准共址资源组的划分,一个控制信道元素中包括的多个准共址资源组中包括的子载波数可以不同。每个准共址资源组关联一个准共址参考信号集合,其中一个准共址资源组中的信道和/或信号关于第一类准共址参数满足准共址关系,不同准共址资源组中的信道和/或信号关于第二类准共址参数不满足准共址关系。
一个控制信道元素中包括的准共址资源组的个数和如下信息至少之一之间有关联:一个信息元素的重复传输次数R、所述一个信息元素的解调参考信号信息、所述一个信息元素的准共址参考信号信息;其中,所述一个信息元素为一个控制信道元素,类似地也可以为一个信号,比如参考信号,同步信号等。
根据本公开提供的实施例,下面以两个码字中包括的是相同信息块的重复传输为示例进行说明。数据信道PDSCH的加扰序列初始化值根据公式(3)得到,其中RNTI是调度PDSCH的DCI的控制信息循环冗余位加扰序列中对应的RNTI范围,是UE-Specific的,q∈{0,1}为码字索引,n ID是高层配置给UE的参数n ID∈{0,1,...,1023},或者n ID是物理小区ID。
c init=n RNTI·2 15+q·2 14+n ID................................(3)。
当一个DCI中调度的两个码字对应一个PDSCH的重复传输,为了终端在解调的时候,即根据接收信号得到调制符号的时候,两个码字可以合并起来处理,为此两个码字中对应RE汇中传输的调制符号相同。为此需要规定,当两个码字中包括相同的控制信息时,两个码字中码字索引q要相同,比如q规定为0。
根据本公开提供的实施例,只有满足约定条件时,两个码字的q值相同,约定条件包括但不限于如下至少之一:一个传输块重复传输时的调制编码速率相同、一个传输块重复传输时的冗余版本相同、多次重复传输是由一个控制信道调度的、多次重复传输占有的资源间隔满足预定特征,比如多次重复传输占有的时域资源的最大间隔不超过预定值,或多次重复传输占有的时域资源的最大间隔不超过预定值占有的频域资源的间隔不超过预定值。
根据本公开提供的实施例,如图20所示,TRP0传输(DCI1,PDSCH1,DMRS0),TRP1传输(DCI2,PDSCH2,DMRS2);其中,DCIi调度PDSCHi,i=1,2,如果DCI1和DCI2之间没有关系, 两个DCI中包括的信息比特可以不同,从而终端需要盲检两个DCI,为了支持这种场景,增加DCI鲁棒性降低终端的盲检复杂度,可以让DCI1和DC2的对应信息比特域相同,但是DCI1和DCI2中相同比特域中,比特域值到指示信息的映射表格不同。
比如DCI中包括的DMRS信息比特指示域包括的比特数为2,其中比特域值和指示新线之间的对应关系为表2所示。如果DCI1和DCI2都采用表2的映射关系,则DCI1中DMRS比特域值为3,则DCI1中DMRS比特域值为6,两个DCI中包括的比特值就不同,从而终端就需要盲检2次;但是可以让DCI1和DCI2对应的映射表格不同,比如DCI1对应表2,DCI2对应表3,从而DCI1和DCI2中的DMRS信息比特域都为3,终端将两个候选控制信道(分别对应两个TRP,如图20中右侧的(b)所示中传输的DCI1联合解码,然后分别采用表2和表3得到TRP1对应的TRP1信息,TRP2对应的DCI2信息,如图20中左侧的(a)所示。

根据本公开提供的实施例,如果TRP1和TRP2不是总同时发送,可能其中一个发送,此时如何知道是如下情况中的哪种{(情况1:TRP1发送图20(b)中的DCI1和PDSCH1),(情况2:TRP2发送图20(b)中的DCI1和PDSCH2),(情况3:TRP1发送图20(b)中的DCI1和PDSCH1,TRP2发送图20(b)中的DCI1和PDSCH2)},一种方案是终端通过盲检候选控制信道1中的DCI1,盲检候选控制信道2中的DCI1,候选控制信道1和候选控制信道2联合起来盲检DCI1,从而知道是上面情况中的哪一种;或者终端假设始终是情况3,只不过情况1中检测不到PDSCH2,针对PDSCH2反馈NACK,情况2中检测不到PDSCH1针对PDSCH1反馈NACK。另一种方案中是图20(b)中DCI1中有一个比特域用于指示当前是情况3中的哪一种,当为情况1时,终端只采用表2解释DCI1的比特域值;当为情况2时,终端只采用表3解释DCI1的比特域值;当为情况3时,终端只表2和表3解释DCI1的比特域值。
上述方案是建立了两个映射表格:表2和表3;另一种方案是还是建立一个映射表,认为表格中的端口索引只是端口在端口集合中的相对索引,在高层信令中通知候选控制信道1(或者候选 控制信道1所在的SSS1/SS1/CORESET1)对应的DMRS端口集合为{0,1,2,3},在高层信令中通知候选控制信道2(或者候选控制信道2所在的SSS2/SS2/CORESET2)对应的DMRS端口集合为{2,3,1,0},当DCI中指示信息为0值,对应的DMRS端口为2,实际上相当于还是两个映射表格,此时虽然是一个映射表格,通过高层信令改变比特域值到指示信息的映射关系,实际上相当于还是两个映射表格,这种情况也称为是两个映射关系表格。
根据本公开提供的实施例,可以规定当DMRS层数小于3时,高层信令中通知候选控制信道2(或者候选控制信道2所在的SSS2/SS2/CORESET2)对应的DMRS端口集合为{2,3,1,0};当DMRS层数大于2时,高层信令中通知候选控制信道2(或者候选控制信道2所在的SSS2/SS2/CORESET2)对应的DMRS端口集合为{1,0,3,2}。
上述是以DCI中的DMRS指示域为例,类似地,一个DCI对应多个比特域与指示信息的映射表格,比特域可以为如下中的一种或者多种:解调参考信号信息比特域、传输配置比特域TCI、进程号信息比特域,或CBG比特域(code block group)。当然也可以是其他比特域,其中,传输比特域TCI用于配置PDSCH的准共址参考信号集合。
根据本公开提供的实施例,一个PDSCH在时域和/或频域可包括多于一个的准共址资源组,其中每个准共址资源组对应准共址参考信号集合,一个DMRS端口组在一个准共址资源组满足准共址关系,一个DMRS端口组在不同准共址资源组中关于一类准共址参数不满足准共址关系。
PDSCH的重复传输次数R、PDSCH的的解调参考信号信息以及PDSCH的准共址参考信号信息中的一种或者多种与一个PDSCH包括的准共址资源组的划分和/或一个PDSCH包括的准共 址资源组的个数有关。
