一种确定信息传输位置的方法及装置
相关申请的交叉引用
本申请要求在2020年05月22日提交中国专利局、申请号为202010442881.8、申请名称为“一种确定信息传输位置的方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种确定信息传输位置的方法及装置。
背景技术
在Rel-15和Rel-16协议中,物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的传输参数的接收位置是由下行控制信息(Downlink Control Information,DCI)的接收位置以及DCI的内容决定的,而且在一个调度单元内,DCI仅在一个物理下行控制信道(Physical Downlink Control Channel,PDCCH)中进行传输。
通常情况下,终端在某时隙接收到PDCCH中传输的DCI,进而确定所述DCI的传输位置,并获取所述DCI中携带的时域资源分配域(Time domain resource assignment,TDRA)信息,其中,所述TDRA域中包含有为终端配置的PDSCH的映射类型信息、PDSCH的时隙偏移信息,以及能够确定PSDCH在时隙中的位置的开始符号和长度符号指示信息等等。进而基于所述时隙偏移信息,以及所述开始符号和长度符号指示信息,确定接收PDSCH中数据信息的传输位置。
然而,当在两个或两个以上的符号或时隙重复传输DCI时,终端可能会接收到多个不同PDCCH中传输的DCI,这样基于多个DCI信息,相应确定可以接收PDSCH中所传输的数据信息的位置,这样可能会导致终端对于 PDSCH的位置判断失误,即终端确定的PDSCH的传输资源和基站发送的PDSCH的传输资源不一致,进而造成无法正确接收PDSCH中传输的数据信息的问题。
例如,参阅图1和图2所示,图1中为终端在一个调度单元内仅在一个PDCCH接收DCI的示意性说明,终端在时隙n接收PDCCH中传输的DCI,根据DCI的内容终端确定PDSCH的时隙偏移为1,并确定所述PDSCH的开始符号和长度符号指示信息,进而确定能够接收PDSCH的位置是图1中时隙n+1的图示位置。
进一步的,图2中示例性的说明了DCI采用时分复用方式在两个或两个以上的符号或时隙进行重复传输的场景,终端在时隙n和时隙n+1分别接收到PDCCH1和PDCCH2传输的DCI,2个DCI均指示PDSCH的时隙偏移为1。根据DCI指示以及PDCCH1的传输位置,终端确定应该在时隙n+1中的图示位置接收PDSCH传输的数据信息,而根据DCI指示以及PDCCH2的传输位置,终端确定应该在时隙n+2中接收PDSCH传输的数据信息,这样,会造成终端无法确定应该根据在哪个时隙接收的DCI确定接收PDSCH的时隙,而且会出现基站在时隙n+1中配置PDSCH传输的数据信息,终端却确定在时隙n+2接收PDSCH传输的数据信息,这样,终端错误的确定了PDSCH的位置,造成PDSCH中传输的数据信息接收失败。

下面结合附图4,对本申请实施例中,对于网络侧确定信息传输位置的流程进行说明。

网络侧将至少两个DCI发送至终端后,进一步的,令终端获得所述至少两个DCI中的至少一个DCI时,触发根据预设规则确定参考传输位置,确定第一物理信道或第一物理信息的传输参数,其中,所述预设规则为预配置信息,或者,在接收所述至少一个DCI之前由高层信令通知。所述参考传输位置的具体确定过程已经在上述附图3的流程中进行详细说明,在此不再赘述。
下面结合以下场景,对本申请涉及到的确定信息传输位置的方法进行进一步详细说明:
终端在一个调度周期内接收到网络侧发送的K个DCI,其中,所述网络侧发送K个DCI的方式可以是时分复用方式或者频分复用方式中的任一种,所述一个调度周期可以是一个时隙或多个时隙,K次重复发送可以在第一时隙或多个时隙的K个控制资源集合里发送,K个DCI对应K个承载DCI的PDCCH,且K个PDCCH中承载的DCI有效载荷和DCI的信息内容相同,即,所述K个DCI的TDRA域,RV指示域,TCI状态指示域等的指示是可以是相同的或者是不完全相同的,其中,对于获取的不完全相同的DCI,所述终端可以基于DCI对应的限定的内容确定第一物理信道或者第一物理信息的传输参数,以下的实施中仅以获得多个内容相同的DCI为例进行说明。
本申请实施例中,一方面,根据参考传输位置确定第一物理信道或第一物理信息的传输参数,另一方面,根据参考传输位置以及DCI的信息内容来确定第一物理信道或第一物理信息的传输参数,其中,所述第一物理信道包括但不限于以下任意一种:物理下行共享信道;物理上行共享信道;采用重复传输方案的物理共享信道;采用重复传输方案的物理上行共享信道。所述第一物理信息包括但不限于CSI-RS。以下的实施例中,仅以物理下行共享信道的传输参数的确定为例进行说明,所述传输参数包括但不限于资源分配信息,冗余版本信息,以及TCI状态指示。
场景一、
终端获取网络侧采用时分复用方式发送的至少一个DCI后,确定参考传输位置为时频资源集合,其中,所述时频资源集合可以是以下任意一种:承载所述至少一个DCI的第一控制信道相关联的,监测时机或搜索空间或控制资源集合;由高层信令配置的时频资源集合;预定义的时频资源集合。如一个控制信道关联的监测时机作为参考传输位置为例,则可以约定所述终端接收到的DCI的信息内容中的偏移量S表征PDSCH的传输位置相对于所述参考传输位置的起始符号S0的偏移量,以及约定所述终端接收到的DCI的信息内容中的时隙偏移K0为PDSCH的传输位置所在的时隙相对于参考传输位置所在时隙的时隙偏移量,其中,所述PDSCH的传输位置表示所述PDSCH的 时域资源分配信息。
例如,参阅图5所示,参考传输位置为预定义的一个控制信道关联的一个检测时机,例如在时间轴上最早进行传输的至少一个PDCCH,即图5中所示终端检测到PDCCH1的位置,且PDCCH1的起始位置为符号3,即sym3,再者,根据PDCCH1所承载的DCI的信息内容,可知,TDRA域中的指示S=3,故可以确定PDSCH的传输位置为符号6,即sym6。因此,网络侧和终端均可确定PDSCH的传输位置开始于符号6。
再例如,参阅图6所示,终端确定参考传输位置为由高层信令通知配置的一个控制信道关联的一个监测时机,即图6中所示将所述终端检测到PDCCH2的传输位置,时隙n+1,作为参考传输位置,且终端基于接收到的DCI的内容,确定TDRA域中的时隙偏移K0为1,因此,网络侧和终端均可确定PDSCH的传输位置所在的时隙为时隙n+2。
场景二、
终端基于获取PDCCH中承载的DCI的信息内容后,确定PDSCH的TCI状态时,并在确定参考传输位置后,基于参考传输位置推算与PDSCH的调度offset(偏移量),并确定所述offset小于预设门限值时,将默认的TCI状态(例如TCI 1)设置为所述PDSCH的TCI状态,反之,若确定所述offset大于或等于预设门限值时,将获取的所述DCI中的TCI状态域指示的TCI状态(例如TCI 2)作为所述PDSCH的TCI状态。
例如,继续参阅图6所示,以PDCCH1的最后一个符号作为参考传输位置时,在没有检测到控制信息前,会假设PDSCH可能在时隙n以及以后的时隙进行传输,假设终端在时隙n接收PDSCH传输的数据信息,基于所述PDCCH1的最后一个符号与假设的PDSCH的位置,计算offset,并将所述offset与预设门限值进行大小比较,假设预设门限值为28个符号,时隙n中的假设PDSCH的位置与PDCCH1的offset是小于28个符号的,所以终端在时隙n使用TCI 1来接收PDSCH。
假设终端在时隙n+2上接收PDSCH传输的数据信息时,此时假设PDSCH 与PDCCH1最后一个符号的offset大于已经门限,终端就会使用TCI 2来接收PDSCH。
同理,对于确定非周期CSI-RS的TCI状态时,同样根据CSI-RS与参考接收位置的offset来确定PDSCH的TCI状态,在此不再赘述。
场景三、
终端重复获取承载于PDCCH中的DCI的信息内容后,确定所述信息内容中满足以下任意条件时,确定所述DCI中不包含TCI状态域:没有配置高层参数tci-PresentInDCI;没有配置无线资源控制tci-PresentInDCI-Format1_2;没有配置下行控制信息格式DCI format为1_0。则定义参考传输位置为承载至少一个DCI的第一控制信道所使用的控制资源集合,或者,定义所述参考传输位置为预定义的控制资源集合,并约定PDSCH的TCI状态与参考传输位置对应的控制资源集合的TCI状态相同。
例如,参阅图7所示,终端获取承载在PDCCH1和PDCCH2中的DCI后,确定DCI的信息内容中不包含TCI状态域,且所述PDCCH1和所述PDCCH2传输使用的控制资源集合不同,在确定参考传输位置为PDCCH1传输所使用的控制资源集合后,则可确定PDSCH的TCI状态为所述PDCCH1传输所使用的控制资源集合的TCI状态。
场景四、
将预定义的时频资源集合设置为参考传输位置,其中,所述时频资源集合包括但不限于以下任意一种:终端获得DCI的一个时隙中的第一个符号或最后一个符号;终端获得DCI的一个时隙;终端获得DCI的第一个符号或最后一个符号。进而基于确定的参考传输位置,以及DCI中携带的TDRA域指示,确定PDSCH的时频资源分配信息,而且由于重复获取的DCI的信息内容相同,故确定的PDSCH的时频资源分配信息唯一。
例如,设置终端获得PDCCH1时的时隙的第一个符号0为参考传输位置,基于所述PDCCH1承载的DCI的信息内容,确定TDRA域中偏移量S为6,故可确定PDSCH的传输位置开始于所述时隙的符号6。此时,即使配置了高 层参数ReferenceofSLIV-ForDCIFormat1_2,也仍然按照参考传输位置来确定PDSCH的传输位置。
场景五、
终端基于获取PDCCH中承载的DCI的信息内容后,确定重复传输的PDSCH的各个传输时机的冗余版本,并在确定参考传输位置后,所述终端进一步确定重复传输的PDSCH占用的时隙编号,以及每次重复传输对应的传输时机,进而可以根据DCI中指示的冗余版本,确定每个时隙的PDSCH使用的冗余版本。
