Description

完全重叠物理下行控制信道候选的传输方法、装置及介质
本公开要求于2021年4月21日提交中国专利局、申请号为202110431522.7、申请名称为“完全重叠物理下行控制信道候选的传输方法、装置及介质”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域,尤其涉及一种完全重叠物理下行控制信道候选的传输方法、装置及介质。
背景技术
随着通信技术的发展,5G NR系统也得到了快速发展。在5G NR系统中,当面向多连接等场景时,大量终端设备(英文全称为:User Equipment,简称为:UE)和基站交互时,基站需要同时下发大量的物理下行控制信道(英文全称为:Physical Downlink Control Channel,简称为:PDCCH)。
而现有技术规定的UE对PDCCH的最大盲检次数不能满足需求,所以考虑基站为不同的下行控制信息(英文全称为:Downlink Control Information,简称为:DCI)格式类型配置相同的有效负荷大小(英文全称为:payload size)。但是这种配置方式在存在属于不同搜索空间(英文全称为:Search Space,简称为:SS)的完全重叠的PDCCH候选时,如果不同搜索空间关联的CORESET相同,UE和基站将无法通过payload size区分完全重叠的PDCCH候选对应的DCI格式,从而导致UE无法正确接收基站发送的PDCCH,增加了PDCCH的堵塞概率。

具体实施方式
本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
为了清楚理解本公开的技术方案,首先对现有技术及技术背景的方案进行详细介绍。
在5G NR系统中,UE的带宽可以动态的变化,每个UE可以设置属于自己的带宽分片(英文全称为:BandWidth Part,简称为:BWP)。在一个BWP内最多可以配置10个SS,高层信令为UE配置的SS的配置信息包括:和当前SS建立联系的CORESET的编号、PDCCH候选的时域起始位置、当前SS是否为UE专属(英文全称为:UE-specific Search Space,简称为:USS)以及当搜索空间为USS时UE需要监听的DCI格式。一个BWP内最多可以配置3个控制资源集合(英文全称为:Control REsource SET,CORESET,简称为:CORESET),高层信令配置的CORESET的配置信息包括:PDCCH候选的频域REG分布以及时域占用的OFDM符号个数等。
基于高层信令中SS和CORESET的配置信息,可知PDCCH候选的时频域位置是由SS和CORESET共同确定的。在UE确定PDCCH候选的时频域位置后需要根据SS中配置的DCI格式对PDCCH候选进行盲检。
在Rel-15/16协议中,UE专属的DCI可以分为回退(英文全称为:fallback)DCI格式(如DCI 0_0/DCI 1_0)、非回退(英文全称为:non-fallback)DCI格式(如DCI 0_1/DCI 1_1)、以及new DCI格式(如DCI 0_2/DCI 1_2三大类)。UE一次盲检仅针对具有相同payload size的DCI格式,UE盲检时通过不同的payload size区分基站发送的不同DCI格式类型。具体来说包括三种情况:如果non-fallback DCI和fallback DCI的配置的payload size相同,non-fallback DCI需要额外增加1bit;new DCI配置的payload size不可以和fallback DCI的相同;non-fallback DCI配置的payload size不可以和new DCI相同。由于不同的SS可能配置了不同DCI格式,如图1所示,当不同的SS和/或CORESET确定的多个PDCCH候选发生完全重叠时,UE可以通过payload size确定相应的DCI格式。在图1中,第一个SS(图1中为SS#1)中的第一个PDCCH候选与第二个SS(图1中为SS#2)中的第一个PDCCH候选发生完全重叠。
额外的,UE在一个时隙内对PDCCH进行盲检时有一定的次数限制。表1为不同 的场景(英文为:case)和子载波间隔下,UE在一个时隙内最大的盲检次数。如果UE在一个时隙内的盲检次数超过限制,则UE在该时隙内不再进行盲检。
表1:UE在一个时隙内最大的盲检次数示意表
Figure PCTCN2022080714-appb-000001
而在5G NR系统中,当面向多连接等场景时,大量终端设备和基站交互时,基站需要同时下发大量的PDCCH,而现有技术规定的UE对PDCCH的最大盲检次数不能满足需求,所以考虑基站为不同的DCI格式类型配置相同的payload size。但是这种配置方式在存在属于不同SS的完全重叠的PDCCH候选时,如果不同搜索空间关联的CORESET相同,UE和基站将无法通过payload size区分完全重叠的PDCCH候选对应的DCI格式,从而导致UE无法正确接收基站发送的PDCCH,进而增加了PDCCH堵塞概率。
为了将完全重叠的PDCCH有效区分,可通过改变完全重叠的PDCCH候选对应的频域位置,从而确定完全重叠的PDCCH候选对应的DCI格式。完全重叠的PDCCH候选可称为待区分的PDCCH候选。而在改变待区分的PDCCH候选对应的频域位置时,可先从各待区分的PDCCH候选的搜索空间中确定需要进行偏移的第一目标搜索空间或目标PDCCH候选,或者从搜索空间中确定进行转移的第二目标搜索空间。再将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移。最终根据偏移结果或转移结果确定各待区分PDCCH候选对应的实际传输位置,以对各待区分PDCCH候选进行区分,进而根据实际传输位置,基站发送对应的PDCCH或者,终端检测接收对应的PDCCH。由于本公开中将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移,能够有效改变完全重叠的PDCCH候选对应的频域位置,所以即使不同DCI格式类型配置相同的payload size的情况下,存在属于不同SS的完全重叠的PDCCH候选时,也能够根据改变后的PDCCH候选对应的实际传输位置准确区分完全重叠的PDCCH候选对应的DCI格式,从而保证终端正确接收基站发送的PDCCH,有效减少PDCCH的堵塞概率。
图2为本公开实施例提供的完全重叠物理下行控制信道候选的传输方法的网络架构图,如图2所示,本公开实施例提供的完全重叠物理下行控制信道候选的传输方法的网络架构为5G NR系统的网络架构,在该网络架构中可以包括:基站1和终端设备。在图2中示例出了两个终端设备,分别为终端设备21和终端设备22。基站1在向终端设备发送PDCCH时,若需要在来自不同SS的完全重叠的PDCCH候选上发送,需要确定每个PDCCH候选对应的实际传输位置。而终端设备在从基站检测及接收PDCCH时,若在来自不同SS的完全重叠的PDCCH候选上检测及接收,需要确定每 个PDCCH候选对应的实际传输位置。则采用本公开实施例提供的完全重叠物理下行控制信道候选的传输方法来确定每个PDCCH候选对应的实际传输位置。

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
实施例一
图3为本公开一实施例提供的完全重叠物理下行控制信道候选的传输方法的流程示意图,如图3所示,本实施例提供的完全重叠物理下行控制信道候选的传输方法的执行主体为完全重叠物理下行控制信道候选的传输装置,该完全重叠物理下行控制信道候选的传输装置位于终端设备中。则本实施例提供的完全重叠物理下行控制信道候选的传输方法包括以下步骤:
步骤101,获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间。
本实施例中,接收基站发送的高层信令中SS的配置信息及CORESET的配置信息。根据SS的配置信息和CORESET的配置信息可确定在每个搜索空间中PDCCH候选对 应的时频域位置,进而确定是否存在完全重叠的待区分PDCCH候选。若确定存在完全重叠的待区分PDCCH候选,则获取完全重叠的待区分PDCCH候选。如图1所示,完全重叠的待区分PDCCH候选来自不同的SS。
步骤102,从搜索空间中确定进行偏移的第一目标搜索空间或目标PDCCH候选,或者从搜索空间中确定进行转移的第二目标搜索空间。
其中,第一目标搜索空间为从完全重叠的待区分PDCCH对应的搜索空间中确定出的需要进行偏移的搜索空间。目标PDCCH候选为从搜索空间对应的待区分PDCCH中确定出的需要进行偏移的PDCCH候选。第二目标搜索空间为从完全重叠的待区分PDCCH对应的搜索空间中确定出的需要进行转移的搜索空间。
本实施例中,第一目标搜索空间为搜索空间中的任意一个或者目标PDCCH候选为任意一个搜索空间中的待区分PDCCH候选。第二目标搜索空间为搜索空间中的任意一个;或者第二目标搜索空间为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间。
步骤103,将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移。
本实施例中,在将第一目标搜索空间或目标PDCCH候选进行偏移时,可首先确定第一目标搜索空间的第一偏移量或目标PDCCH候选的第二偏移量,然后根据第一偏移量将第一目标搜索空间在关联的控制资源集合中进行偏移,或者根据第二偏移量将目标PDCCH候选在对应的搜索空间关联的控制资源集合中进行偏移。
或者本实施例中,在将第二目标搜索空间进行转移时,可首先第二目标搜索空间转移到的备用控制资源集合;将第二目标搜索空间转移到备用控制资源集合中。
步骤104,根据偏移结果或转移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH。
本实施例中,若将第一目标搜索空间或目标PDCCH候选进行偏移,则获取偏移结果,根据偏移结果确定各待区分PDCCH候选对应的实际传输位置,进而根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
或者本实施例中,若将第二目标搜索空间进行转移,则获取转移结果,根据转移结果确定各待区分PDCCH候选对应的实际传输位置,进而根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
本实施例提供的完全重叠物理下行控制信道候选的传输方法,通过获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间;从搜索空间中确定进行偏移的第一目标搜索空间或目标PDCCH候选,或者从搜索空间中确定进行转移的第二目标搜索空间;将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移;根据偏移结果或转移结果确定各 待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH。由于将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移,能够有效改变完全重叠的PDCCH候选对应的频域位置,所以即使不同DCI格式类型配置相同payload size的情况下,存在属于不同SS的完全重叠的PDCCH候选时,也能够根据改变后的PDCCH候选对应的实际传输位置准确区分完全重叠的PDCCH候选对应的DCI格式,从而保证终端正确接收基站发送的PDCCH,有效减少PDCCH的堵塞概率。
实施例二
图4为本公开另一实施例提供的完全重叠物理下行控制信道候选的传输方法的流程示意图,如图4所示,本实施例提供的完全重叠物理下行控制信道候选的传输方法在本公开实施例一提供的完全重叠物理下行控制信道候选的传输方法的基础上,为对第一目标搜索空间或目标PDCCH候选进行偏移,以确定各待区分PDCCH候选对应的实际传输位置的技术方案,则本实施例提供的完全重叠物理下行控制信道候选的传输方法包括以下步骤:
步骤201,获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间。
本实施例中,步骤201的实现方式与本公开实施例一中的步骤101的实现方式类似,在此不再一一赘述。
步骤202,从搜索空间中确定进行偏移的第一目标搜索空间或目标PDCCH候选。
可选地,本实施例中,第一目标搜索空间为搜索空间中的任意一个。
或者,目标PDCCH候选为任意一个搜索空间中的待区分PDCCH候选。
需要说明的是,本实施例中,终端设备通过与基站的交互,虽然确定出的第一目标搜索空间为搜索空间中的任意一个,或者目标PDCCH候选为任意一个搜索空间中的待区分PDCCH候选,但终端设备确定出的第一目标搜索空间与基站确定出的第一目标搜索空间相同。或者终端设备确定出的目标PDCCH候选与基站确定出的目标PDCCH候选相同。
步骤203,将第一目标搜索空间或目标PDCCH候选进行偏移。
相应地,步骤203包括以下步骤:
步骤2031,确定第一目标搜索空间的第一偏移量或目标PDCCH候选的第二偏移量。
作为一种可选实施方式,本实施例中,步骤2031包括以下步骤:
步骤2031a,获取与基站通过协议预先设定的搜索空间偏移量或预先设定的PDCCH候选偏移量。
步骤2031b,将预先设定的搜索空间偏移量确定为第一偏移量,或者将预先设定的PDCCH候选偏移量确定为第二偏移量。
在该种可选实施方式中,终端设备可以与基站通过协议预先设定搜索空间偏移量,将预先设定的搜索空间偏移量确定为第一目标搜索空间的第一偏移量。或者终端设备 与基站通过协议预先设定PDCCH候选偏移量,将预先设定的PDCCH候选偏移量确定为目标PDCCH候选的第二偏移量。
作为另一种可选实施方式,本实施例中,步骤2031包括以下步骤:
步骤20311,接收基站发送的第一配置信息。
步骤20312,从第一目标搜索空间的第一配置信息中确定第一偏移量或者从目标PDCCH候选对应的搜索空间的第一配置信息中确定第二偏移量。
在该种可选实施方式中,基站发送给终端设备的第一配置信息可以是第一目标搜索空间对应的配置信息或者目标PDCCH候选对应的搜索空间的配置信息,该第一配置信息中包括新增的对应搜索空间的偏移量(英文为:SearchSpaceOffset)或搜索空间中待区分PDCCH候选的偏移量(英文为:PDCCHcandidateOffset)。
所以在本实施例中,终端设备获取第一目标搜索空间的第一配置信息,从第一目标搜索空间的第一配置信息中确定第一偏移量。或者终端设备获取目标PDCCH候选对应的搜索空间的第一配置信息,从目标PDCCH候选对应的搜索空间的第一配置信息中确定第二偏移量。
在上述两种可选实施方式中,第一偏移量为第一预定义的CCE数量,第一预定义的CCE数量包括以下任意一种CCE数量:
整个目标搜索空间所占的CCE数量、目标搜索空间中部分搜索空间所占的CCE数量、任意一个待区分PDCCH候选所占用的CCE数量。
其中,第二偏移量为第二预定义的CCE数量,第二预定义的CCE数量为任意一个待区分PDCCH候选占用的CCE数量。
可选地,在所述第一偏移量和所述第二偏移量为任意一个待区分PDCCH候选所占用的CCE数量时,第一偏移量和第二偏移量均为各待区分PDCCH候选中占用的最大CCE数量。
步骤2032,根据第一偏移量将第一目标搜索空间在关联的控制资源集合中进行偏移,或者根据第二偏移量将目标PDCCH候选在对应的搜索空间关联的控制资源集合中进行偏移。
本实施例中,在第一目标搜索空间的配置信息中包括与第一目标搜索空间建立联系的CORESET的编号,通过该建立联系的CORESET的编号确定与第一目标搜索空间关联的CORESET。进而根据第一偏移量将第一目标搜索空间在关联的控制资源集合中进行偏移。
或者本实施例中,在目标PDCCH候选对应的搜索空间的配置信息中包括目标PDCCH候选对应的搜索空间建立联系的CORESET的编号,通过该建立联系的CORESET的编号确定与目标PDCCH候选对应的搜索空间关联的CORESET,进而根据第二偏移量将目标PDCCH候选在对应的搜索空间关联的控制资源集合中进行偏移。
作为一种可选实施方式,步骤203中,将目标PDCCH候选进行偏移之后,还包括以下步骤:
若偏移后的目标PDCCH候选与任意一个搜索空间中的PDCCH候选再次完全重叠, 则对偏移后的目标PDCCH候选继续进行偏移,直到目标PDCCH候选与任意一个搜索空间中的PDCCH候选不再完全重叠为止。
其中,偏移次数小于或等于预设偏移次数阈值,预设偏移次数阈值预先设定或由高层信令配置。
具体地,本实施例中,将偏移后的目标PDCCH候选对应的时频域位置与所有搜索空间的PDCCH候选对应的时频域位置进行对比,判断偏移后的目标PDCCH候选对应的时频域位置是否与任意一个搜索空间中的PDCCH候选再次完全重叠。若是,则还需要继续对偏移后的目标PDCCH候选进行偏移。在继续对偏移后的目标PDCCH候选进行偏移前,判断偏移次数是否小于或等于预设偏移次数阈值,若是,则执行对偏移后的目标PDCCH候选继续进行偏移的步骤。若否,则停止对偏移后的目标PDCCH候选继续进行偏移。
其中,预设偏移次数阈值是预先设定或由高层信令配置的,具体的数值不作限定。
步骤204,根据偏移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH。
本实施例中,根据偏移结果重新确定待区分PDCCH候选对应的时频域位置,该重新确定的待区分PDCCH候选对应的时频域位置为对应的实际传输位置。该实际传输位置是不同的,所以可根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
需要说明的是,在步骤204之前,本实施例提供的完全重叠物理下行控制信道候选的传输方法还包括以下步骤:
根据各待区分PDCCH候选对应的初始传输位置检测及接收对应的PDCCH。
判断根据各待区分PDCCH候选对应的初始传输位置是否检测及接收到对应的PDCCH。
相应地,步骤204包括:
若未接收到对应的PDCCH候选,则根据实际传输位置,检测及接收对应的PDCCH。
其中,根据实际传输位置检测及接收对应的PDCCH时,当前时隙内检测PDCCH候选对应的传输位置是否存在对应的PDCCH需要接收的次数总和小于当前时隙内的最大盲检次数。
具体地,本实施例中,在确定完全重叠的待区分PDCCH候选后,待区分PDCCH候选具有相同的初始传输位置。则终端设备根据各待区分PDCCH候选对应的初始传输位置检测及接收对应的PDCCH。但由于待区分PDCCH候选具有相同的初始传输位置,导致终端无法接收对应的PDCCH。而将第一目标搜索空间或目标PDCCH候选进行偏移后,无法正确接收的PDCCH改变了初始传输位置,具有了新的实际传输位置。所以在未接收到对应的PDCCH后,根据实际传输位置,检测及接收对应的PDCCH。但由于当前时隙内的盲检次数不能超过最大盲检次数。所以当前时隙内检测PDCCH候选对应的传输位置是否存在对应的PDCCH需要接收的次数总和小于当前时隙内的 最大盲检次数。
本实施例提供的完全重叠物理下行控制信道候选的传输方法,通过获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间,从搜索空间中确定进行偏移的第一目标搜索空间或目标PDCCH候选,将第一目标搜索空间或目标PDCCH候选进行偏移,根据偏移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH,能够在第一目标搜索空间或目标PDCCH候选进行偏移后,有效改变完全重叠的PDCCH候选的初始传输位置,根据改变后的PDCCH候选对应的实际传输位置准确区分完全重叠的PDCCH候选对应的DCI格式,从而保证终端正确接收基站发送的PDCCH,有效减少PDCCH的堵塞概率。
为了更加清楚地描述本实施例提供的完全重叠物理下行控制信道候选的传输方法,下面进行示例性说明。
示例一
在示例一提供的完全重叠物理下行控制信道候选的传输方法中,步骤202为:从搜索空间中确定进行偏移的第一目标搜索空间,步骤203为:将第一目标搜索空间进行偏移。在步骤2031中确定第一目标搜索空间的第一偏移量时,获取与基站通过协议预先设定的搜索空间偏移量,将预先设定的搜索空间偏移量确定为第一偏移量。
在示例一中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。SS#1中包含3个聚合等级(简称:AL)为2的PDCCH候选,SS#2中包含2个AL为4的PDCCH候选。确定SS#2为第一目标搜索空间。则SS#2的第一偏移量是与基站通过协议预先设定的第一偏移量。具体第一偏移量的大小不作限定。在图5a-图5c中示意出了第一偏移量为不同取值后,对SS#2进行偏移后两个SS中PDCCH候选的情况。在图5a中,SS#2的第一偏移量为整个SS的大小(即为22个CCE)。图5b中,SS#2的第一偏移量为1/2SS大小(即为11个CCE),可以理解的是,部分偏移量占SS大小的比例可以任意定义。在图5c中,SS#2的第一偏移量为完全重叠的待区分PDCCH候选大小(即为4个CCE)。如图5a-图5c所示,SS#2进行偏移后,两个SS内原本完全重叠的两个待区分PDCCH候选将不会完全重叠或者部分完全重叠,无论CCE-REG采用集中式/分布式映射,两个待区分PDCCH候选对应的频域位置不完全相同,进而待区分PDCCH候选对应的实际传输位置不相同,UE可通过实际传输位置区分这两个PDCCH候选对应的DCI格式,根据两个PDCCH候选对应的DCI格式接收及检测对应的PDCCH。
由于第一目标搜索空间为完全重叠的待区分PDCCH候选对应的搜索空间中的任意一个,所以第一目标搜索空间也可以为SS#1。相应地,也可通过偏移SS#1来区分两个完全重叠的PDCCH,则SS#1对应的第一偏移量为与基站通过协议预先设定的搜索空间偏移量。具体实现方式与第一目标搜索空间为SS#2时类似,在此不再一一赘述。
但是在示例一中,如图5c所示,SS#2偏移4个CCE后导致SS#1中的第三个PDCCH候选和SS#2中的第二个PDCCH候选发生新的完全重叠,所以偏移整个SS 会引入新的完全重叠问题。由于CORESET和SS的配置情况比较复杂,因此在偏移整个SS的方案中预先设定的搜索空间偏移量无法完全避免新的完全重叠产生,并非较好方案。
所以本实施例在步骤2031中确定第一目标搜索空间的第一偏移量时,提供了接收基站发送的第一配置信息,从第一目标搜索空间的第一配置信息中确定第一偏移量的技术方案,具体参加示例二
示例二
在示例二提供的完全重叠物理下行控制信道候选的传输方法中,步骤202为:从搜索空间中确定进行偏移的第一目标搜索空间,步骤203为:将第一目标搜索空间进行偏移。在步骤2031中确定第一目标搜索空间的第一偏移量时,接收基站发送的第一配置信息,从第一目标搜索空间的第一配置信息中确定第一偏移量。
在示例二中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。SS#1中包含3个聚合等级(简称:AL)为2的PDCCH候选,SS#2中包含2个AL为4的PDCCH候选。确定SS#2为第一目标搜索空间。高层信令在第一目标搜索空间对应的第一配置信息中配置了对应搜索空间的偏移量(英文为:SearchSpaceOffset)。搜索空间的偏移量用于指示SS如果存在和其他SS中PDCCH候选完全重叠的PDCCH候选时,该SS需要偏移的偏移量。搜索空间的偏移量有多个候选值,如包括:{0,1,2,3}个CCE等,本实施例不做限制。当SearchSpaceOffset取值为0时,表示对应的搜索空间不需要进行偏移。
如图6所示,在示例二中,SS#2为第一目标搜索空间,SS#2对应的第一偏移量取值为1个CCE。所以将SS#2进行1个CCE的偏移。在进行1个CCE偏移后,两个SS内原本完全重叠的两个待区分PDCCH候选将部分完全重叠,无论CCE-REG采用集中式/分布式映射,两个待区分PDCCH候选对应的频域位置不完全相同,进而待区分PDCCH候选对应的实际传输位置不相同,UE可通过实际传输位置区分这两个PDCCH候选对应的DCI格式,根据两个PDCCH候选的DCI格式接收及检测对应的PDCCH。
由于第一目标搜索空间为完全重叠的待区分PDCCH候选对应的搜索空间中的任意一个,所以第一目标搜索空间也可以为SS#1。相应地,也可通过偏移SS#1来区分两个完全重叠的PDCCH,则SS#1对应的第一偏移量为SS#1的第一配置信息中确定出的第一偏移量。具体实现方式与第一目标搜索空间为SS#2时类似,在此不再一一赘述。
示例三
在示例三提供的完全重叠物理下行控制信道候选的传输方法中,步骤202为:从搜索空间中确定进行偏移的目标PDCCH候选。步骤203为:将目标PDCCH候选进行偏移。步骤2031中确定目标PDCCH候选的第二偏移量时,获取与基站通过协议预先设定的PDCCH候选偏移量,将预先设定的PDCCH候选偏移量确定为第二偏移量。
在示例三中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2 为例进行说明。确定SS#2中的第一个PDCCH候选为目标PDCCH候选。则SS#2中的第一个PDCCH候选的第二偏移量是与基站通过协议预先设定的第二偏移量。具体第二偏移量的大小不作限定。在图7中示意出了第二偏移量为占用4个CCE大小。在SS#2中的第一个PDCCH候选进行偏移后,SS#1的第一个PDCCH候选和SS#2的第一个PDCCH候选不再完全重叠。无论CCE-REG采用集中式/分布式映射,SS#1的第一个PDCCH候选和SS#2的第一个PDCCH候选的频域位置不完全相同,进而SS#1的第一个PDCCH候选和SS#2的第一个PDCCH候选对应的实际传输位置不相同,UE可通过实际传输位置区分这两个PDCCH候选对应的DCI格式,根据两个PDCCH候选对应的DCI格式接收及检测对应的PDCCH。
由于目标PDCCH候选为任意一个搜索空间中的待区分PDCCH候选,所以目标PDCCH候选也可以为SS#1的第一个PDCCH候选。相应地,也可通过偏移SS#1的第一个PDCCH候选来区分两个完全重叠的PDCCH,则SS#1的第一个PDCCH候选对应的第二偏移量为与基站通过协议预先设定的PDCCH候选偏移量。具体实现方式与目标PDCCH候选为SS#2的第一个PDCCH候选时类似,在此不再一一赘述。
示例四
在示例四提供的完全重叠物理下行控制信道候选的传输方法中,步骤202为:从搜索空间中确定进行偏移的目标PDCCH候选。步骤203为:将目标PDCCH候选进行偏移。步骤2031中确定目标PDCCH候选的第二偏移量时,接收基站发送的第一配置信息,从目标PDCCH候选对应的搜索空间的第一配置信息中确定第二偏移量。
在示例四中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。确定SS#2中的第一个PDCCH候选为目标PDCCH候选。目标PDCCH候选对应的搜索空间的第一配置信息中包括对应搜索空间的待区分PDCCH的偏移量(英文为:PDCCHcandidateOffset)。PDCCHcandidateOffset用于指示搜索空间中如果存在和其他SS中PDCCH候选完全重叠的PDCCH候选时,该搜索空间内完全重叠的PDCCH候选需要偏移的偏移量。PDCCHcandidateOffset可以有多个候选值,如包括:{0,1,2,3}个CCE等,本实施例不做限制。当PDCCHcandidateOffset取值为0时,表示对应搜索空间内的待区分PDCCH候选不需要偏移。
如图8所示,示例四中,SS#2的第一个PDCCH候选确定为目标PDCCH候选。SS#2中PDCCHcandidateOffset的取值为1个CCE,SS#1中PDCCHcandidateOffset的取值为0。所以在SS#2的第一个PDCCH候选进行1个CCE偏移后,两个SS内原本完全重叠的两个待区分PDCCH候选将部分完全重叠,无论CCE-REG采用集中式/分布式映射,两个待区分PDCCH候选对应的频域位置不完全相同,进而待区分PDCCH候选对应的实际传输位置不相同,UE可通过实际传输位置区分这两个PDCCH候选对应的DCI格式,根据两个PDCCH候选对应的DCI格式接收及检测对应的PDCCH。
由于目标PDCCH候选为任意一个搜索空间中的待区分PDCCH候选,所以目标PDCCH候选也可以为SS#1的第一个PDCCH候选。相应地,也可通过偏移SS#1的第一个PDCCH候选来区分两个完全重叠的PDCCH,则SS#1的第一个PDCCH候选对 应的第二偏移量为SS#1的第一配置信息中确定出的第二偏移量。具体实现方式与第一目标搜索空间为SS#2时类似,在此不再一一赘述。
实施例三
图9为本公开再一实施例提供的完全重叠物理下行控制信道候选的传输方法的流程示意图,如图9所示,本实施例提供的完全重叠物理下行控制信道候选的传输方法在申请实施例一提供的完全重叠物理下行控制信道候选的传输方法的基础上,是将第二目标搜索空间进行转移,并根据转移结果确定各待区分PDCCH候选对应的实际传输位置的技术方案,则本实施例提供的完全重叠物理下行控制信道候选的传输方法包括以下步骤:
步骤301,获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间。
本实施例中,步骤301的实现方式与本公开实施例一中的步骤101的实现方式类似,在此不再一一赘述。
步骤302,从搜索空间中确定进行转移的第二目标搜索空间。
其中,第二目标搜索空间为搜索空间中的任意一个。或者第二目标搜索空间为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间。
需要说明的是,本实施例中,终端设备通过与基站的交互,虽然确定出的第二目标搜索空间为搜索空间中的任意一个,或者为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间,但终端设备确定出的第二目标搜索空间与基站确定出的第二目标搜索空间相同。
若第二目标搜索空间为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间,则将待区分PDCCH候选放入当前带宽切片BWP内的新的搜索空间中,新的搜索空间的索引编号沿用待区分PDCCH候选对应的原搜索空间的索引编号。
或者若第二目标搜索空间为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间,则将待区分PDCCH候选放入当前BWP内的新的搜索空间中,新的搜索空间的索引编号配置为当前BWP内未被占用的索引编号。
本实施例中,无论新的搜索空间的索引编号沿用待区分PDCCH候选对应的原搜索空间的索引编号还是配置为当前BWP内未被占用的索引编号,均能够使新的搜索空间中的待区分PDCCH候选对应的实际传输位置区别于与其发生完全重叠的其他搜索空间中的待区分PDCCH候选对应的实际传输位置。
其中,新搜索空间按照所有待区分的PDCCH候选配置每个聚合等级包含的PDCCH候选数目,新搜索空间的其他配置参数与原搜索空间对应的配置参数相同。
步骤303,将第二目标搜索空间进行转移。
作为一种可选实施方式,本实施例中,步骤303包括以下步骤:
步骤3031,确定第二目标搜索空间转移到的备用控制资源集合。
作为一种可选实施方式,本实施例中,备用控制资源集合为预先设定的控制资源集合。
其中,预先设定的控制资源集合为第二目标搜索空间关联的控制资源集合相邻的前一个控制资源集合或后一个控制资源集合,或者为预定义的默认控制资源集合。
在该种可选实施方式中,示例性的,若当前BWP内配置的控制资源集合的编号为{#0,#1,#2}。第二目标搜索空间原有关联的CORESET编号为#1。则作为一种可选实施方式,第二目标搜索空间需要转移到的备用CORESET编号为#2。或者第二目标搜索空间需要转移到的备用CORESET为预定义的默认控制资源集合,则预定义的默认控制资源集合编号为#2。
作为另一种可选实施方式,本实施例中,步骤3031包括以下步骤:
步骤3031a,接收基站发送的第二配置信息;
步骤3031b,从第二目标搜索空间的第二配置信息中确定转移到的备用控制资源集合。
具体地,在该种可选实施方式中,基站发送给终端设备的第二配置信息为第二目标搜索空间对应的配置信息,该第二配置信息中包括新增的搜索空间当前关联的控制资源集合的编号。在第二目标搜索空间的第二配置信息中包括第二目标搜索空间当前关联的控制资源集合的编号,该当前关联的控制资源集合的编号即为转移到的备用控制资源集合的编号。
需要说明的是,在上述两种可选实施方式中,备用控制资源集合为当前BWP内配置的控制资源集合,且备用控制资源集合为终端设备专属的控制资源集合。
步骤3032,将第二目标搜索空间转移到备用控制资源集合中。
步骤304,根据转移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH。
本实施例中,由于将第二目标搜索空间转移到了备用控制资源集合中,不同的控制资源集合占用不同的频域资源,所以待区分的PDCCH候选映射到完全独立的频域资源中,此时UE可通过频域位置对待区分的PDCCH候选对应的实际传输位置进行区分,根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
需要说明的是,在步骤304之前,本实施例提供的完全重叠物理下行控制信道候选的传输方法还包括以下步骤:
根据各待区分PDCCH候选对应的初始传输位置检测及接收对应的PDCCH。

其中,根据实际传输位置检测及接收对应的PDCCH时,当前时隙内检测PDCCH候选对应的传输位置是否存在对应的PDCCH需要接收的次数总和小于当前时隙内的最大盲检次数。
本实施例中,步骤304的具体实现方式与实施例二中的步骤204的实现方式类似,在此不再一一赘述。
本实施例提供的完全重叠物理下行控制信道候选的传输方法,通过获取完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间,从搜索空间中确定进行转移的第二目标搜索空间,将第二目标搜索空间进行转移,根据转移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置,检测及接收对应的PDCCH,由于将第二目标搜索空间进行转移后,不同的控制资源集合占用不同的频域资源,所以待区分的PDCCH候选映射到完全独立的频域资源中,能够有效避免再次出现PDCCH候选出现完全重叠的情况,提高了基站和终端设备间传输PDCCH候选的效率。
为了更加清楚地描述本实施例提供的完全重叠物理下行控制信道候选的传输方法,下面进行示例性说明。
示例五
示例五提供的完全重叠物理下行控制信道候选的传输方法中,第二目标搜索空间为搜索空间中的任意一个。在步骤3031中确定第二目标搜索空间转移到的备用控制资源集合时,备用控制资源集合为预先设定的控制资源集合。
在示例五中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。假设当前BWP配置了三个CORESET编号为{#0,#1,#2},且SS#1和SS#2原来关联的CORESET编号均为#1。通过将SS#1关联到当前BWP内配置的其他CORESET以区分两个SS中存在完全重叠的PDCCH候选。其中,SS#1为第二目标搜索空间。SS#1关联到的备用控制资源集合为预先设定的控制资源集合。如SS#1当前关联的CORESET编号可以是原来关联CORESET编号的后一个,即CORESET#2。CORESET#2为UE专属的CORESET。若SS#1当前关联的CORESET编号为来关联CORESET编号的前一个,即CORESET#0,则不属于UE专属的CORESET。由于不同的控制资源集合占用不同的频域资源,所以待区分的PDCCH候选映射到完全独立的频域资源中,此时UE可通过频域位置对待区分的PDCCH候选对应的实际传输位置进行区分,根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
由于第二目标搜索空间为搜索空间中的任意一个,所以第二目标搜索空间也可以为SS#2。相应地,也可通过将SS#2关联到当前BWP内配置的其他CORESET来区分两个SS中存在完全重叠的PDCCH候选。SS#2关联的新CORESET编号由基站和UE预先设定。具体实现方式与第一目标搜索空间为SS#1时类似,在此不再一一赘述。
示例六
示例六提供的完全重叠物理下行控制信道候选的传输方法中,第二目标搜索空间为搜索空间中的任意一个。在步骤3031中确定第二目标搜索空间转移到的备用控制资源集合时,通过接收基站发送的第二配置信息;从第二目标搜索空间的第二配置信息 中确定转移到的备用控制资源集合。
在示例六中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。假设当前BWP配置了三个CORESET编号为{#0,#1,#2},且SS#1和SS#2关联的CORESET编号均为#1。通过将SS#1关联到当前BWP内配置的其他CORESET以区分两个SS中存在完全重叠的PDCCH候选。其中,SS#1为第二目标搜索空间。高层信令在第二目标搜索空间对应的第二配置信息中配置了当前关联的备用控制资源集合(英文为:ControlResourceSetId-reserved)。通过ControlResourceSetId-reserved确定SS#1转移后的CORESET编号。由于不同的控制资源集合占用不同的频域资源,所以待区分的PDCCH候选映射到完全独立的频域资源中,此时UE可通过频域位置对待区分的PDCCH候选对应的实际传输位置进行区分,根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
由于第二目标搜索空间为搜索空间中的任意一个,所以第二目标搜索空间也可以为SS#2。相应地,也可通过将SS#2关联到当前BWP内配置的其他CORESET来区分两个SS中存在完全重叠的PDCCH候选。SS#2关联的新CORESET编号由ControlResourceSetId-reserved确定的。具体实现方式与第二目标搜索空间为SS#1时类似,在此不再一一赘述。
示例七
示例七提供的完全重叠物理下行控制信道候选的传输方法中,第二目标搜索空间为由任意一个搜索空间中的待区分PDCCH候选组建的新搜索空间。新的搜索空间的索引编号沿用待区分PDCCH候选对应的原搜索空间的索引编号,或者新的搜索空间的索引编号配置为当前BWP内未被占用的索引编号。
在示例七中,以完全重叠的待区分PDCCH候选分别来自图1中的SS#1和SS#2为例进行说明。假设当前BWP配置了三个CORESET编号为{#0,#1,#2},且SS#1和SS#2关联的CORESET编号均为#1。通过将SS#1关联到当前BWP内配置的其他CORESET以区分两个SS中存在完全重叠的PDCCH候选。其中,SS#1为第二目标搜索空间。SS#1内需要转移的所有PDCCH候选组成一个新的SS,该新SS的索引可以继续为#1,也可以是当前BWP内所有SS未占用的索引编号,且该新的SS内只有一个聚合等级为2的PDCCH候选,新的SS内的其他参数和SS#1内的参数配置完全相同。新的SS当前关联的CORESET编号确定方式和示例五和示例六中相同,所以不再详细介绍。由于不同的控制资源集合占用不同的频域资源,所以待区分的PDCCH候选映射到完全独立的频域资源中,此时UE可通过频域位置对待区分的PDCCH候选对应的实际传输位置进行区分,根据实际传输位置确定各待区分PDCCH所属的搜索空间,根据各待区分PDCCH所属的搜索空间的配置信息确定待区分PDCCH对应的DCI格式,根据DCI格式检测及接收对应的PDCCH。
由于第二目标搜索空间为搜索空间中的任意一个,所以第二目标搜索空间也可以 为SS#2。相应地,也可通过将SS#2中的待区分PDCCH候选组建的新搜索空间,并关联到当前BWP内配置的其他CORESET来区分两个SS中存在完全重叠的PDCCH候选。具体实现方式与第二目标搜索空间为SS#1时类似,在此不再一一赘述。

本实施例提供的完全重叠物理下行控制信道候选的传输方法,通过确定完全重叠的待区分物理下行控制信道PDCCH候选,各待区分PDCCH候选分别来自不同的搜索空间,从搜索空间中确定进行偏移的第一目标搜索空间或目标PDCCH候选,或者从搜索空间中确定进行转移的第二目标搜索空间,将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移,根据偏移结果或转移结果确定各待区分PDCCH候选对应的实际传输位置,并根据实际传输位置发送对应的PDCCH,由于将第一目标搜索空间或目标PDCCH候选进行偏移,或者将第二目标搜索空间进行转移,能够有效改变完全重叠的PDCCH候选对应的频域位置,所以即使不同DCI 格式类型配置相同的payload size的情况下,存在属于不同SS的完全重叠的PDCCH候选时,也能够根据改变后的PDCCH候选对应的实际传输位置准确区分完全重叠的PDCCH候选对应的DCI格式,从而保证终端正确接收基站发送的PDCCH,有效减少PDCCH的堵塞概率。
