具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
可以理解,本申请的技术方案可应用于第五代移动通信(the 5th Generation,5G)***或者称为新无线(New Radio,NR)***、长期演进(Long Term Evolution,缩写:LTE)等***,此处不一一列举。此外,本申请的技术方案可具体应用于数据传输设备中,用于进行数据传输,比如根据TCI state进行数据传输等。可选的,该数据传输设备可以是终端,也可以是网络设备。
请参见图1,是本申请提供的一种通信***的架构图。如图1所示,该通信***可以包括:一个或多个网络设备101,以及,一个或多个终端102,图1中仅示出一个网络设备101和一个终端102作为示例。该网络设备101和终端102之间可以进行数据传输。为了提升数据传输的可靠性,通信***引入了重复传输技术,即重传技术。网络设备101和终端102可以通过对数据的重复传输,即将数据如携带相同数据的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)通过不同的时隙/TRP/冗余版本等多次传输,从而有助于获得分集增益,降低误检概率如块误码率(Block Error Rate,BLER),进而提升数据传输可靠性。
在可能的设计中,该重复传输可以在多个时隙进行,如图2a所示;也可以在多个数据传输设备如传输点/发送接收点(Transmission/reception point,TRP)上进行,如图2b所示。例如,对于多时隙的重复,该重复传输对应的多个携带相同数据的PDSCH可以通过DCI来调度在连续的多个时隙上传输,也可以在非连续的多个时隙上传输,传输时可采用相同的频域资源。又如,对于多TRP的重复,携带相同数据的PDSCH可在不同TRP上分别传输,数据传输设备可以采用不同的传输参数如不同的波束(该传输参数可通过TCI指示,比如此时可在一个DCI中指示多个TCI state,每个TCI state用于一次重复传输)。多TRP的重复也可以和多时隙的方式结合,采用非连续的时隙来传输,或者采用连续的时隙来传输,在不同的时隙采用不同的TRP进行传输等等。从而有助于提升数据传输可靠性,并有助于确保超可靠、低时延通信(Massive Machine Type Communications,URLLC)的低时延高可靠特性等。
由此,在重复传输的场景下,数据传输设备可以根据每次重复传输对应的TCI state来进行数据传输,如采用TCI state对应的传输参数进行数据传输。对于该重复传输,可能存在配置传输资源发生变化的情况,比如该重复传输可能存在中断的情况,或者存在其他导致重复传输的配置传输资源发送变化的情况。如果配置传输资源发生变化,数据传输设备如上述的终端、网络设备,无法确定应该采用何种TCI state来进行数据传输,可能导致数据无法正确接收或发送。例如,某些***的上下行配置较为灵活,某些时刻可能存在一些比较重要的***信息等,会导致多重复传输发生部分中断,如图2c和2d所示,4次重复传输中第二次传输被优先级更高的***消息如SSB中断,重复传输的资源发生变化。对于重复传输的资源发生变化如中断传输的情况,没有明确的TCI映射方式,导致数据传输设备无法确定实际传输对应的TCI state以进行数据传输,如无法确定应该采用何种TCI state对应的TRP的信道估计滤波参数来接收正常传输的数 据。由此,本申请能够在重复传输对应的时域资源发生变化时,根据配置传输对应的第一TCI state序列和第一时域资源对应的实际传输,来确定该第一时域资源对应的第二TCI state序列,进而能够根据该第二TCI state序列进行数据传输,使得能够实现在重复传输的配置资源发生变化时,确定出可采用的TCI state来进行数据传输,其可以在非连续的传输资源中采用正确的TCI state进行数据的接收或发送,有助于提升数据传输的可靠性,并有助于确保URLLC的正确传输,达到低时延高可靠的目的。
在本申请中,网络设备可以为网络侧的一种用来发送或接收信息的实体,比如可以为基站,基站可以用于与一个或多个终端进行通信,也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站之间的通信,如接入点之间的通信)。基站可以是基站收发台(Base Transceiver Station,BTS),也可以是长期演进(Long Term Evolution,LTE)***中的演进型基站(Evolutional Node B,eNB),还可以是5G***、NR***中的基站gNB,等等,此处不一一列举。或者,该网络设备101还可以是传输点(transmission point,TP)、接入点(Access Point,AP)、传输点/发送接收点(transmission and receiver point,TRP)、中继设备、中心单元(Central Unit,CU),或者具备基站功能的其他网络设备等等,本申请不做限定。
在本申请中,终端是具有通信功能的设备,例如可以是车载设备、可穿戴设备、手持设备(如智能手机)等。该终端还可以叫做其余名称,比如用户设备(User Equipment,UE)、用户单元、移动台(mobile station)、移动单元(mobile unit)、终端设备等等,本申请不做限定。
在本申请中,该重复传输可以包括上行传输的至少一次传输,或者,该重复传输也可以包括下行传输的至少一次传输,本申请不做限定。
在本申请中,TCI state序列可以包括顺序排列的至少一个TCI state(以下可以简称TCI)。也就是说,TCI state序列包括至少一个TCI state,且该至少一个TCI state是按照一定顺序排列的。
可以理解,图1示出的通信***只是作为一种示例,并不构成对本申请的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请提供的技术方案对于类似的技术问题,同样适用。
本申请公开了一种数据传输方法及相关设备,数据传输设备能够在重复传输的配置资源发生变化时,确定出可采用的TCI来进行数据传输,有助于提升数据传输的可靠性。下面结合附图进行详细描述。
请参见图3,图3是本申请实施例提供的一种数据传输方法的流程示意图。本实施例的方法可具体应用于上述的数据传输设备中,该数据传输设备可以是终端,也可以是网络设备。如图3所示,该数据传输方法可以包括:
301、确定用于数据的重复传输的第一TCI state序列。
其中,该第一TCI state序列可包括至少一个TCI state,该重复传输的每次传输和该第一TCI state序列中的一个TCI state关联,即该重复传输的每次传输对应该第一TCI state序列中对应位置的TCI state。例如,该重复传输的首次传输(初传、第一次传输)和第一TCI state序列的第一个TCI state关联,该重复传输的第二次传输和第一TCI state序列的第二个TCI state关联,以此类推,即该重复传输的第n次传输和第一TCI state序列的第n个TCI state关联。重复传输的第n次传输和第n个TCI state关联可以是指,进行该第n次传输时根据该第n个TCI state进行数据传输,比如根据该第n个TCI state对应的接收参数接收数据,又如根据该第n个TCI state对应的发送参数发送数据等等。
该第一TCI state序列可以是指重复传输的配置传输对应的TCI state序列,或者说重复传输的配置传输资源即第二时域资源对应的TCI state序列。可选的,该第一TCI state序列可以是根据TCI配置信息确定出的,或者可以是网络设备配置的,或者可以是预先存储的,或者还可以是通过其他方式确定出的。
在一种可能的设计中,数据传输设备可获取TCI配置信息,进而在确定第一TCI state序列时,根据该TCI配置信息确定该第一TCI state序列。其中,该TCI配置信息可用于指示至少一个TCI state,或者可用于指示该第一TCI state序列。可选的,该TCI配置信息可包括一个或多个TCI索引,和/或,多个TCI state和该多个TCI state的配置顺序,和/或,一个或多个TCI state所属的CORESET的组索引,等等,从而数据传输设备可结合这些信息来确定TCI配置信息指示的TCI state,确定TCI配置信息指示的TCI state的顺序,以及确定该第一TCI state序列等等。进一步可选的,该TCI配置信息可包括该重复传输的配置传输次数。例如,该TCI配置信息可用于指示至少一个TCI state,或者用于指示至少一种TCI state,数据传输设备可根据重复传输的配置传输次数(重传次数)以及该TCI配置信息,来确定该第一TCI state序列;又如,该TCI配置信息可用于指示该第一TCI state序列,比如直接携带该第一TCI state序列,或者可包括该第一TCI state序列的各TCI对应的索引(TCI索引或所属组索引等)及顺序,以使数据传输设备根据该索引及顺序确定该第一TCI state序列等等。
如果该数据传输设备为终端,网络设备可向终端发送TCI配置信息,终端可接收来自网络设备的TCI配置信息。可选的,该TCI配置信息还可用于指示该至少一个TCI state的顺序,从而数据传输设备可根据该顺序确定第一TCI state序列包括的各TCI state的顺序;或者,数据传输设备可通过其他方式确定该第一TCI state序列包括的各TCI state的顺序,比如随机确定该至少一种TCI state的顺序、根据该至少一种TCI state的索引确定该顺序、根据该至少一种TCI state所属的控制资源集CORESET的组索引确定该顺序等等,本申请不做限定。其中,该配置传输次数可携带于该TCI配置信息中,也可以携带于其他信息,通过其他信息发送给终端,或者可以是终端通过其他方式确定出的。
示例的,数据传输设备在确定该第一TCI state序列时,可根据该重传次数,依次对该TCI配置信息指示的至少一个TCI state进行轮询,以得到该第一TCI state序列。如基于第一TCI配置信息中的第一TCI state(以下简称第一TCI)用于第1,第j+1,第2j+1次传输,第二TCI state(以下简称第二TCI)用于第2,第j+2,第2j+2次传输,第三TCI state(以下简称第三TCI)用于第3,第j+3,第2j+3次传输,以此类推。例如,该重传次数为4次,TCI配置信息指示了该第一TCI和第二TCI,对该第一TCI和第二TCI轮询后,得到该第一TCI state序列可以为第一TCI、第二TCI、第一TCI、第二TCI,即第一TCI用于第1次和第3次传输,第二TCI用于第2次和第4次传输。又如,该重传次数为6次,TCI配置信息指示了该第一TCI和第二TCI,则该第一TCI state序列可以为第一TCI、第二TCI、第一TCI、第二TCI、第一TCI、第二TCI,即第一TCI用于第1次、第3次和第5次传输,第二TCI用于第2次、第4次和第6次传输。又如,该重传次数为6次,该TCI配置信息指示了该第一TCI、第二TCI和第三TCI,则该第一TCI state序列可以为第一TCI、第二TCI、第三TCI、第一TCI、第二TCI、第三TCI,即第一TCI用于第1次和第4次传输,第二TCI用于第2次和第5次传输,第三TCI用于第3次和第6次传输,等等,此处不一一列举。
示例的,数据传输设备在确定该第一TCI state序列时,还可根据该重传次数,分别确定该至少一种TCI state中每种TCI state在该第一TCI state序列中的数目,进而根据每种TCI state的数目,确定该第一TCI state 序列。如可以是基于第一TCI配置信息中的第一TCI用于第1至k次传输,第二TCI用于第k+1至2k次传输,第三TCI用于第2k+1至第3k次传输,以此类推。例如,该重传次数为4次,TCI配置信息指示了第一TCI和第二TCI,得到该第一TCI state序列可以为第一TCI、第一TCI、第二TCI、第二TCI,即第一TCI用于第1次和第2次传输,第二TCI用于第3次和第4次传输。又如,该重传次数为5次,TCI配置信息指示了第一TCI和第二TCI,则该第一TCI state序列可以为第一TCI、第一TCI、第一TCI、第二TCI、第二TCI,即第一TCI用于第1-3次传输,第二TCI用于第4-5次传输。又如,该重传次数为6次,该TCI配置信息指示了第一TCI、第二TCI和第三TCI,则该第一TCI state序列可以为第一TCI、第一TCI、第二TCI、第二TCI、第三TCI、第三TCI,即第一TCI用于第1-2次传输,第二TCI用于第3-4次传输,第三TCI用于第5-6次传输,等等,此处不一一列举。
302、当该重复传输对应的时域资源发生变化时,根据该第一TCI state序列中的TCI state和第一时域资源对应的每次传输的对应关系,确定该第一时域资源对应的第二TCI state序列。
其中,该第一时域资源为发生变化后的重复传输对应的时域资源,该第二TCI state序列可包括至少一个TCI state。数据传输设备确定第一时域资源对应的第二TCI state序列可以是指:分别确定第一时域资源中对应的每次传输(各重复传输)所对应的TCI state,或者分别确定第一时域资源中各重复传输对应的时域资源所对应的TCI state,即确定重复传输的每次实际传输对应的TCI state。也就是说,数据传输设备能够根据重复传输对应的每次实际传输和第一TCI state序列中的TCI state的映射关系,确定重复传输的每次实际传输的TCI配置,即第二TCI state序列。
在一种可能的设计中,该重复传输对应的第二时域资源发生变化,可以是指该第二时域资源的部分资源(如某次配置传输或某几次配置传输对应的资源)变化,或者可以是指该第二时域资源的全部资源变化;其还可称为配置传输被中断、配置传输资源被占用等等。可选的,该变化可能由多种情况导致,比如某次配置传输被中断如被优先级更高的***信息中断导致变化,或者说某次配置传输对应的配置传输资源被占用如被优先级更高的***信息占用,或者主动调整该重复传输的时域资源,或者是传输资源发生变化的其他情况,本申请不做限定。
在一种可能的设计中,数据传输设备可根据该第一TCI state序列和目标信息,确定该第一TCI state序列中的TCI state和第一时域资源对应的每次传输的对应关系。其中,该目标信息可用于指示实际使用的传输资源,或者说可用于指示该第一时域资源对应的每次传输的位置,数据传输设备可根据目标信息确定第一时域资源对应的每次传输。可选的,该目标信息包括以下任一项或多项:该第一时域资源的位置信息如该第一时域资源对应的每次传输的位置信息、该第一时域资源对应的传输次数、第二时域资源中首次传输所对应的时域资源(假设记为第三时域资源)的位置信息、该重复传输的配置传输次数、发生变化的时域资源的位置信息;该第二时域资源为时域资源发生变化前的重复传输对应的时域资源,且该第一时域资源对应的传输次数小于或等于该重复传输的配置传输次数。可选的,第三时域资源可以为直接配置或间接配置的时域资源。该位置信息可包括资源起始位置、长度、结束位置中的任一项或多项,比如包括起始位置和长度,又如包括起始位置和结束位置等等。如果该数据传输设备为终端,该目标信息可以是网络设备发送给终端的,或者可以是终端通过其他方式确定的。

在一种可能的设计中,该TCI可以包括准共址(QuasiCo-location,QCL),数据传输设备可根据QCL的指示来确定进行数据传输时的波束,比如网络设备可通过QCL的指示来通知终端在进行数据传输的接收波 束,又如网络设备可根据QCL确定发送波束等等。可选的,QCL的可以通过以下方式指示:通过RRC配置指示,或者可以通过RRC配置并由MAC-CE激活,或者通过RRC配置并由MAC-CE激活并利用DCI进行指示。对于基于MAC-CE的指示方式,可以由高层配置一组TCI state,根据每个TCI state可以确定相应的QCL参考。对于基于DCI的指示方式,QCL信息的获取可经历RRC配置、MAC-CE激活以及DCI指示三个步骤。例如,以数据传输设备为终端为例,对于多TRP重复传输,由于不同TRP在空间上的位置差异会导致接收链路上的大尺度信道参数的差别,终端在接收来自不同TRP的数据时可以使用不同的接收参数如信道估计滤波参数,为了简化终端在每次接收数据时调整信道估计滤波参数,网络设备可通过QCL的指示来通知终端在进行数据接收时的接收波束,以提升数据传输的可靠性。
在一种可能的设计中,数据传输设备在确定出该第二TCI state序列之后,还可将该第二TCI state序列发送给对应的设备以进行数据传输,比如该数据传输设备为终端时,可将该第二TCI state序列发送给网络设备以进行数据传输,又如该数据传输设备为网络设备时,可将该第二TCI state序列发送给终端以进行数据传输,从而有助于节省***确定实际传输对应的TCI的开销。
在其他可选的实施例中,数据传输设备还可仅确定发生变化的重复传输对应的实际传输资源所对应的TCI state,及发生变化的重复传输对应的配置传输资源之后的其他配置传输资源所对应的TCI state,该第四时域资源之前的重复传输仍可以以第一TCI state序列中对应的TCI state进行数据传输,以提升数据传输效率。
