为便于理解本申请实施例的技术方案,以下对本申请实施例涉及到的相关技术进行说明。
在NR系统中,终端通过网络侧配置的CORESET和搜索空间(Search Space)来确定检测物理下行控制信道(Physical Downlink Control Channel,PDCCH)的资源。其中,CORESET用于确定PDCCH在一个时隙内的频域资源大小(如占用的PRB数目)和时域资源大小(如占用的OFDM符号数目),包括频域资源起始位置,频域资源长度和时域资源长度等。而搜索空间用于确定PDCCH的时域资源位置,包括时域资源起始位置和监测周期。根据一个COSRESET和一个搜索空间配置,终端可以确定检测PDCCH的物理资源位置,如图2中斜线填充的资源。
具体的,参照图3,网络侧通过高层信令(如RRC信令)配置最多三个CORESET,每个CORESET有自己的CORESET ID。同时,网络侧还可以通过高层信令先配置至少一个搜索空间,每个搜索空间的配置参数包括该搜索空间关联的CORESET的ID,聚合等级,搜索空间类型等。每个搜索空间只能关联一个CORESET,但是一个CORESET可以关联多个搜索空间。其中,搜索空间类型包括该搜索空间为公共搜索空间(Common Search Space,CSS)还是UE专属搜索空间(User Search Space,USS)的配置,以及终端需要在该搜索空间中需要检测的下行控制信息(Downlink Control Information,DCI)格式。如果搜索空间为CSS,则搜索空间中的搜索空间类型(searchSpaceType)配置为公共(Common),且相应需要检测的DCI格式包括DCI format 2_0、DCI format 2_1、DCI format 2_2、DCI format 2_3、DCI format 0_0和DCI format 1_0等格式中的至少一个,即该DCI一般用于调度控制信息的传输。如果搜索空间是USS,则相应需要检测的DCI格式包括DCI format 0_0和DCI format 1_0(formats0-0-And-1-0),或者包括DCI format 0_1和DCI format 1_1(formats0-1-And-1-1),即该DCI一般用于调度上行或下行数据传输。
在NR系统中引入了基于多个TRP的下行和上行的非相干传输。其中,TRP之间的回程(backhaul)连接可以是理想的或者非理想的,理想的backhaul下TRP之间可以快速动态的进行信息交互,非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。在下行非相干传输中,多个TRP可以采用不同的控制信道独立调度一个终端的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输,所调度的PDSCH可以在相同的时隙或不同的时隙传输。终端需要支持同时接收来自不同TRP的PDCCH和/或PDSCH。终端反馈ACK/NACK时,可以将ACK/NACK各自反馈给传输相应PDSCH的不同TRP(如图4-1所示),也可以合并上报给一个TRP(如图4-2所示)。前者可以应用于理想backhaul和非理想backhaul两种场景,后者只能用于理想backhaul的场景。其中不同TRP发送的PDSCH可以携带相同的数据,这样通过多TRP的分集传输可以进一步提高PDSCH的传输可靠性。此时,终端针对携带相同数据的多个PDSCH只需要上报一个ACK/NACK即可。其中,不同TRP传输的用于调度PDSCH的PDCCH可以通过不同的CORESET或CORESET组来承载,即网络侧配置多个CORESET或CORESET组,每个TRP采用各自的CORESET或CORESET组进行调度。
在上行非相干传输中,不同TRP同样可以独立调度同一个终端的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输。不同PUSCH传输可以配置独立的传输参数,例如波束、预编码矩阵、层数等。所调度的PUSCH传输可以在同样的时隙或不同的时隙传输。如果终端在同一个时隙被同时调度了两个PUSCH传输,则需要根据自身能力确定如何进行传输。如果终端配置有多个天线面板(panel),且支持在多个panel上同时传输PUSCH,则可以同时传输这两个PUSCH,且不同panel上传输的PUSCH对准相应的TRP进行模拟赋形,从而通过空间域区分不同的PUSCH,提供上行的频谱效率(如图5-1所示)。如果终端只有单个panel,或者不支持多个panel同时传输,则只能在一个panel上传输PUSCH(如图5-2所示)。其中,不同TRP传输的用于调度PUSCH的DCI可以通过不同的CORESET或CORESET组来承载,即网络侧配置多个CORESET或CORESET组,每个TRP采用各自的CORESET或CORESET组进行调度。
在NR系统中,各信道/信号所采用的加扰序列如下:

(q)(i)是一个伪随机序列,具体是一个长度为31的Gold序列,输出序列c(n)的长度为M

由这两个高层参数确定。
如果DMRS相应的PDSCH/PUSCH是由DCI format 0_0或1_0调度的且相应PDCCH的CRC采用C-RNTI,或者MCS-C-RNTI,或者CS-RNTI加扰,且高层参数配置了scramblingID0,则
由该高层参数确定。
如果DMRS相应的PDSCH/PUSCH由DCI format 0_1或1_1调度,则n
SCID∈{0,1}由该DCI中的DMRS序列初始化指示域确定;如果PUSCH是一个type 1的PUSCH传输,则n

按照上述加扰序列生成方法,不同TRP调度的信号是采用相同的加扰序列初始化值,从而会得到相同的加扰序列。这样,当不同TRP调度的信号的传输资源重叠时,这些信号之间会产生严重的干扰,从而影响信号的传输性能。为此,提出了本申请实施例的以下技术方案。
