Description

系统消息冗余版本确定方法及装置
本申请要求在2018年4月4日提交中国国家知识产权局、申请号为201810299694.1、发明名称为“系统消息冗余版本确定方法及装置”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，尤其涉及一种系统消息冗余版本确定方法及装置。
背景技术
无线通信网络中，系统消息是网络设备下发给终端设备的系统级别或小区级别的消息。例如，LTE(long term evolution)中的系统消息可以是系统消息块(System Information Block，SIB)，且定义有不同的SIB(SIB1、SIB2等)，不同的SIB承载不同功能的信息。
LTE的SIB1的传输时间间隔(Transmission Time Interval，TTI)为80毫秒(ms)。所述TTI为80ms，是指在80ms内，发送的SIB1承载的都是相同的信息，在下一个80ms才会发送承载不同信息的SIB1。SIB1的发送周期为20ms，因此其在80ms的TTI内会重复发送4次，即在SFN(System Frame Number)为偶数的无线帧(也可称作系统帧)上传输SIB1，其中SFN表示无线帧的帧号。4次SIB1传输采用不同的冗余版本(Redundancy Version，RV)，具体来说，上述4次SIB1传输采用的RV分别为0、2、3、1。图1A给出了上述SIB1传输的一个例子。在SIB1 TTI周期80ms内的第一个20ms发送周期内的第一个无线帧(即SFN＝0对应的无线帧)传输RV为0的SIB1，在第二个20ms内的第一个无线帧(即SFN＝2对应的无线帧)传输RV为2的SIB1，在第三个20ms内的第一个无线帧(即SFN＝4对应的无线帧)传输RV为3的SIB1，在第四个20ms内的第一个无线帧(即SFN＝6对应的无线帧)传输RV为1的SIB1，且上述4个SIB1均承载相同的信息。
对于LTE的SIB2，其发送周期为160ms，其遵循基于窗口的传输，所述窗口是指配置的一个时段，SIB2只能在所述窗口中进行传输，且SIB2在一个所述窗口中至少有一次传输。图1B给出了LTE中SIB2传输的一个例子，以无线帧长度为10ms为例。图1B中示意了两个SIB2窗口，每个窗口包含两个无线帧，一个窗口包含无线帧0和无线帧1，另一个窗口包含无线帧16和无线帧17，且两个窗口之间的时间间隔为SIB2的发送周期(即160ms)。每一个上述窗口中包含20个长度为1ms的子帧。所述20个子帧上能够承载的SIB2的RV是由SIB2所在子帧的标识确定的，具体来说，在包含无线帧16和无线帧17的窗口中，{i＝0，i＝4，i＝8，i＝12，i＝16}的5个子帧可以承载RV为0的SIB2，{i＝1，i＝5，i＝9，i＝13，i＝17}的5个子帧可以承载RV为2的SIB2，{i＝2，i＝6，i＝10，i＝14，i＝18}的5个子帧可以承载RV为3的SIB2，{i＝3，i＝7，i＝11，i＝15，i＝19}的5个子帧可以承载RV为1的SIB2。
又例如，新空口(New Radio，NR)网络中，波束成型技术用来将传输信号的能量限制在某个方向内，从而增加信号在该方向上的接收效率。为了增强覆盖，波束成型需结合波束扫描以尽可能多而全的覆盖不同方向，并且系统消息需支持冗余版本的收发。

进一步地，上述系统消息的传输可以是类似于图1B所示例的基于窗口的传输。一个窗口可以包含一个或多个子窗口。一个子窗口可以理解成所述窗口内的一个时段，可以包含一个或多个时域资源单元(例如符号，微时隙，时隙，子帧，无线帧或采样点等)，所述一个或多个时域资源单元可以在时域上离散或连续。一个子窗口可以与一个同步信号块关联，所述同步信号块可以是可能传输的同步信号块或实际传输的同步信号块。所述一个子窗口与一个同步信号块关联是指该子窗口内承载系统消息的波束与承载该子窗口关联的同步信号块的波束一致；或者是指该子窗口内承载的系统消息与关联的同步信号块具有准共址(Qusi Co-located，QCL)的关系，其中QCL关系表示两个信号在多普勒扩展、多普勒频移、平均增益、空域参数等方面可以是相同的或者相通的。所述子窗口内可以传输一个或多个所述系统消息，且所述系统消息可以采用一个或多个波束传输。不同的子窗口可以重叠，也可以不重叠。

可以理解的是，本发明实施例对子窗口包含的时域资源单元的数量、分布、类型等均不作限制。例如图3B给出了另一种可能的窗口和子窗口的示意，与图3A相比，图 3B中是以系统消息子窗口包含时域上连续时域资源单元为例的：系统消息子窗口1包含无线帧16中的时隙0-4；系统消息子窗口2包含无线帧16中的时隙5-9；系统消息子窗口3包含无线帧17中的时隙0-4；系统消息子窗口4包含无线帧17中的时隙5-9。
如上所述，系统消息采用波束成型或波束扫描的方式收发时，通过不同的波束扫描不同的方向完成系统消息在多个方向上的传输。波束扫描一轮或一圈持续的时间或时域资源单元数量可以称为波束扫描周期。例如系统消息使用6个波束发送，一个波束使用1个时隙，则所述系统消息的波束扫描周期为6个时隙。系统消息窗口包含至少一个波束扫描周期，所述波束扫描周期可以有其索引或编号，所述索引或编号用以在所述系统消息窗口内标识所述波束扫描周期。可选地，所述系统消息窗口长度可以为波束扫描周期的倍数(例如可以是1倍，2倍，3倍，4倍，6倍，8倍，16倍，12倍，10倍，32倍，20倍，24倍，28倍，36倍，40倍，44倍，48倍，52倍，56倍，60倍，64倍，或68倍等)。可选地，系统消息窗口可以与半静态上下行资源分配周期具有相同的时域起始位置。所述半静态上下行资源分配周期可以是网络设备通过高层信令半静态地为终端设备配置的，终端设备通过该配置还可以获得所述半静态上下行资源分配周期内的下行时域资源单元、灵活时域资源单元和上行时域资源单元；终端通过上述配置，可以获得所述半静态上下行资源分配周期在时域上的位置和时长，以及所述半静态上下行资源分配周期内的下行时域资源单元、灵活时域资源单元和上行时域资源单元在时域上的分布。所述下行时域资源单元可以用作下行传输；所述上行时域资源单元可以用作上行传输；所述灵活时域资源单元可以用作下行传输或上行传输，网络设备可以通过下行控制信令告知终端设备所述灵活时域资源单元的传输方向。
在采用波束成型或波束扫描的无线通信系统(例如NR)中，系统消息可以采用波束成型或波束扫描的方式收发。承载在一个波束上的系统消息在时域资源单元上传输，并采用对应的RV进行收发。所述时域资源单元可以为符号，微时隙(mini-slot)，时隙，子帧，无线帧或采样点等。如果仍然采用图1A或图1B所示意的方法确定时域资源单元对应的RV，可能出现可以承载该系统消息的波束在某些时域资源单元上无法支持有效的RV，导致系统消息在该时域资源单元上无法收发，从而导致承载系统消息波束的数量减少，进而导致系统消息的覆盖变差。
图3C以一种波束扫描下剩余最小系统消息(Remaining Minimum System Information，RMSI)的传输为例来进一步阐明上述问题，其中RMSI为NR系统中定义的一种系统消息，也可以称为NR-SIB0信息、NR-SIB1信息或者NR-SIB2信息。图3C示意了16个无线帧(即SFN＝0的无线帧-SFN＝15的无线帧)，每个无线帧持续时长以10ms为例，RMSI的TTI以160ms为例。若仍按照图1A所示的方法(即RVk＝(ceil(3/2*k))mod 4，其中k＝(SFN/2)mod 4)确定某个无线帧上传输RMSI使用的RV，则只有SFN为偶数的无线帧(即SFN＝0，2...14)能够获得有效的RV，而SFN为奇数的无线帧(即SFN＝1，3...15)无法通过上述方式获得有效的RV。原因是当SFN为奇数时，SFN/2不是整数，因此无法再对4进行取模操作。由此可以看出，在图3C所示的16个无线帧中，仅有8个无线帧上的波束可以承载RMSI的有效RV，其余8个无线帧上的波束无法承载RMSI的有效RV，因此会导致承载RMSI的波束数量减少，进而导致RMSI的覆盖变差，影响系统性能。
本发明实施例提供的系统消息冗余版本确定方法及装置，通过增加能够承载系统消息有效RV的时域资源单元数量，解决了上述某些时域资源单元上的波束无法支持系统消 息的有效RV进而承载系统消息波束数量减少的问题，从而提高了系统消息的覆盖范围。
本发明实施例中的系统消息的种类包含RMSI或其他系统消息(Other System Information，OSI)中的至少一种。其中RMSI可以携带上行随机接入配置信息、OSI的调度信息、以及同步信号和同步信号块的周期信息等内容中的至少一项内容；OSI可以携带SIB2，SIB3，SIB4...等系统消息块中的至少一种SIB信息，也可以携带其他系统信息，这些系统信息可以用作小区切换，频率切换，网络切换等。需要理解的是，本发明实施例也可以应用于其他种类的系统消息，例如LTE或NR中的SIB、系统信息块、基于广播的系统消息、基于随机接入过程请求的系统消息等，本发明对此不做限定。本领域技术人员可以理解，本发明中以RMSI为例的实施例也可以应用于OSI或其他种类的系统消息，以OSI为例的实施例也可以应用于RMSI或其他种类的系统消息。

下面以具体实施例结合附图对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图4为本申请实施例提供的一种系统消息冗余版本确定方法的流程图。如图4所示，本实施例的方法可以包括：
401部分，通信设备确定至少一个时域资源单元Ux，其中x可以理解为所述时域资源单元的标识或索引。
402部分，所述通信设备根据所述时域资源单元Ux确定系统消息在所述时域资源单元Ux的冗余版本RVx，所述冗余版本RVx满足RVx＝(Int1(X1/X2*(Int2(x/M)mod K)))mod L，其中x为非负整数，X1和X2为非零实数，M为正实数，K和L为正整数；mod表示取模(A mod B表示A对B进行取模操作或运算)；Int1表示上取整或下取整的操作或运算，Int2表示上取整或下取整的操作或运算。其中RVx中的x与Ux中的x可以理解为对应的。

可选地，所述时域资源单元的标识x可以在一个时段内独立编号，即所述时域资源单元的标识x可以是一个时段内的时域资源单元索引或时域资源单元编号。以图5B为例示意了三个时间上离散的窗口(即窗口0、窗口1和窗口2)，所述窗口可以理解为所述的一个时段，例如所述窗口可以为图3A和图3B中描述的系统消息窗口或系统消息子窗口。图5B示意了在窗口1中包含32个时隙，所述非负整数x在图5B中以x＝0，x＝1，...，x＝31标识图5B窗口1内的32个时隙。以窗口0包含64个时隙、窗口2包含32个时隙为例，则所述非负整数x以x＝0，x＝1，...，x＝63标识图5B窗口0内的64个时隙，以x＝0，x＝1，...，x＝31标识图5B窗口2内的32个时隙。图5B中示意的窗口数量、窗口的位置以及窗口内的时域资源单元数量仅为示例，例如窗口数量可以是除了3以外的值，窗口之间在时间上可以是连续的，窗口内的时域资源单元数量可以是除了32、64以外的值，窗口内的时域资源单元可以是符号、微时隙、时隙、子帧、无线帧或采样点等。若所述窗口为图3A和图3B中描述的系统消息窗口，则窗口的时间长度可以是50ms，60ms，70ms，80ms，90ms，100ms，110ms，120ms，130ms，140ms，150ms，160ms，320ms，或640ms等，例如可以为80ms或160ms，或者80ms和160ms。
可选地，所述时域资源单元的标识x还可以是一个时段内的下行时域资源单元索引或下行时域资源单元编号，或者是一个时段内的可以用作下行传输的时域资源单元索引或可以用作下行传输的时域资源单元编号。所述一个时段与图5B中的描述类似，在此不再赘述。所述可以用作下行传输的时域资源单元可以包含下行时域资源单元和灵活时域资源单元中的至少一种。
可选地，所述时域资源单元的标识x还可以是实际传输的同步信号块的索引，或是可能传输的同步信号块的索引，或是系统消息子窗口的索引，或是与实际传输或可能传输的同步信号块x关联的系统消息子窗口的索引，或是波束扫描周期的索引。

在402部分中，所述通信设备根据所述时域资源单元Ux，确定系统消息在所述时域资源单元Ux的冗余版本RVx。图6给出了一套详细的确定所述系统消息在所述时域资源单元Ux的冗余版本RVx的流程示例。图6的流程仅以图4402部分中示意的公式为例进行描述。可以理解的是，采用其他方法或公式获得本发明实施例提供的技术效果的也属于本发明的保护范畴。
在601部分中，通信设备根据x/M确定参数x1，即x1＝x/M，其中M为正实数。
进一步地，所述M可以为预定义的正实数，即采用602部分。在第一种示例中，以M＝2为例，则x1＝x/2。604部分中，所述通信设备对所述参数x1下取整获得参数x2，则x2＝floor(x1)＝floor(x/2)，其中floor(Q2)表示对Q2进行向下取整操作或运算，Q2为正实数。需要说明的是，向下取整也可以称为下取整，还可以使用
Figure PCTCN2019079493-appb-000001
表示；对Q2下取整也可以通过对Q2上取整再减1实现；如果Q2本身就是整数，则floor(Q2)也可理解为不做下取整操作，即floor(Q2)＝Q2。额外需要说明的是，本申请中ceil(Q1)表示对Q1进行向上取整操作或运算，Q1为正实数；向上取整也可以称为上取整，还可以使用
Figure PCTCN2019079493-appb-000002
表示；对 Q1上取整也可以通过对Q1下取整再加1实现；如果Q1本身就是整数，则ceil(Q1)也可理解为不做上取整操作，即ceil(Q1)＝Q1。
605部分与606部分中，所述通信设备可以根据所述参数x2，确定参数x3，再根据所述参数x3，确定系统消息在所述时域资源单元Ux的冗余版本RVx。在605部分中，所述通信设备可以采用参数x2对K取模确定所述参数x3，其中K为预定义的正整数。例如K可以是预定义的RV个数，以K取4为例，可以理解为预定义有4个RV(例如RV＝0，RV＝2，RV＝3，RV＝1)，则x3＝x2mod K＝x2 mod 4＝floor(x/2)mod 4。可以理解的是，本申请实施例在605部分中并不限定K的具体取值。例如，K还可以取2或8，则可以理解为预定义有2个或8个RV。
进一步地，在606部分中，所述通信设备可以根据RVx＝(ceil(3/2*(x3)))mod L获得系统消息在所述时域资源单元Ux的冗余版本RVx，其中L为预定义的正整数。例如L可以是预定义的RV个数，以L取4为例，可以理解为预定义有4个RV(例如RV＝0，RV＝2，RV＝3，RV＝1)，则RVx＝(ceil(3/2*(x3)))mod L＝(ceil(3/2*(floor(x/2)mod 4)))mod 4。可以理解的是，本申请实施例在606部分中并不限定L的具体取值。例如L还可以取2，则可以理解为预定义有2个RV。可以理解的是，上述公式可以理解为图4402部分中的X1和X2分别取3和2。此外，在606部分中所述通信设备还可以根据其他公式获得系统消息在所述时域资源单元Ux的冗余版本RVx，例如可以采用下列公式中的任意一个：
RVx＝ceil(3/2*(x3))mod L、RVx＝ceil(1/2*(x3))mod L、RVx＝ceil(5/2*(x3))mod L、RVx＝ceil(7/2*(x3))mod L、RVx＝ceil(1/3*(x3))mod L、RVx＝ceil(2/3*(x3))mod L、RVx＝ceil(4/3*(x3))mod L、RVx＝ceil(5/3*(x3))mod L、RVx＝ceil(7/3*(x3))mod L、RVx＝ceil(1/4*(x3))mod L、RVx＝ceil(3/4*(x3))mod L、RVx＝ceil(5/4*(x3))mod L、RVx＝ceil(7/4*(x3))mod L、RVx＝ceil(1/5*(x3))mod L、RVx＝ceil(2/5*(x3))mod L、RVx＝ceil(3/5*(x3))mod L、RVx＝ceil(4/5*(x3))mod L、RVx＝ceil(6/5*(x3))mod L、RVx＝ceil(7/5*(x3))mod L、RVx＝ceil(1/6*(x3))mod L、RVx＝ceil(5/6*(x3))mod L、RVx＝ceil(7/6*(x3))mod L、RVx＝ceil(1/7*(x3))mod L、RVx＝ceil(2/7*(x3))mod L、RVx＝ceil(3/7*(x3))mod L、RVx＝ceil(4/7*(x3))mod L、RVx＝ceil(5/7*(x3))mod L或RVx＝ceil(6/7*(x3))mod L。上述公式中的ceil也可以替换为floor；X1和X2还可以有其他的取值；此外，X1/X2还可以理解为一个整体，例如X1/X2可以是一个常数。
602部分的第二种示例中，以M＝4为例，则x1＝x/4。604部分中，所述通信设备对所述参数x1上取整获得参数x2，则x2＝ceil(x1)＝ceil(x/4)，其中ceil(Q2)表示对Q2进行向上取整操作或运算，Q2为正实数。605部分与606部分与前述类似，在此不再赘述。则可以获得系统消息在所述时域资源单元Ux的冗余版本为RVx＝(ceil(3/2*(x3)))mod L＝(ceil(3/2*(ceil(x/4)mod 4)))mod 4。
图7A给出了依据上述第一种和第二种示例得到的系统消息在时域资源单元Ux的冗余版本RVx示意。图7A以系统消息是RMSI，且有标识为x＝0，x＝1，...，x＝15的16个无线帧为例，示意了可以承载RMSI冗余版本RVx。图7A中所有的16个无线帧均可以支持RMSI的有效RV，因此所示意的16个无线帧中的波束均可用作RMSI的波束成型或波束扫描，与图3C示意的现有方案相比，增加了能够用于承载RMSI的波束数量，从而增强了RMSI在波束成型或波束扫描下的覆盖。
图7B以RMSI为例，示意了在一个RMSI TTI中RMSI的PDSCH使用的RV。图7B中RMSI在时域资源单元Ux的冗余版本RVx与图7A一致。以RMSI TTI为160ms、RMSI发送周期为40ms为例，RMSI在一个TTI中可以在无线帧{x＝0，x＝4，x＝8，x＝12}上传输，且在x＝0和x＝8的无线帧上RMSI的PDSCH的RV＝0，在x＝4和x＝12的无线帧上RMSI的PDSCH的RV＝3，共采用了两种RV完成一个TTI内的RMSI收发。以RMSI TTI为160ms、RMSI发送周期为80ms为例，RMSI在一个TTI中可以在无线帧{x＝0，x＝8}上传输，且在x＝0和x＝8的无线帧上RMSI的PDSCH的RV＝0，共采用了一种RV完成一个TTI内的RMSI收发。
602部分的第三种示例中，以M＝4为例，则x1＝x/4。604部分中，所述通信设备对所述参数x1下取整获得参数x2，则x2＝floor(x1)＝floor(x/4)。605部分和606部分与前述类似，在此不再赘述。则可以获得系统消息在时域资源单元Ux的冗余版本为RVx＝(ceil(3/2*(floor(x/4)mod 4)))mod 4。
602部分的第四种示例中，以M＝8为例，则x1＝x/8。604部分中，所述通信设备对所述参数x1上取整获得参数x2，则x2＝ceil(x1)＝ceil(x/8)。605部分和606部分与前述类似，在此不再赘述。则可以获得系统消息在时域资源单元Ux的冗余版本为RVx＝(ceil(3/2*(ceil(x/8)mod 4)))mod 4。
图8A给出了依据上述第三种和第四种示例得到的系统消息在时域资源单元Ux的冗余版本RVx示意。图8A以系统消息是RMSI、且有标识为x＝0，x＝1，...，x＝15的16个无线帧为例，示意了可以承载RMSI冗余版本RVx。图8A中所有的16个无线帧均可以支持RMSI的有效RV，因此所示意的16个无线帧中的波束均可用作RMSI的波束成型或波束扫描，与图3C示意的现有方案相比，增加了能够用于承载RMSI的波束数量，从而增强了RMSI在波束成型或波束扫描下的覆盖。
图8B以RMSI为例，示意了RMSI TTI中RMSI的PDSCH使用的RV。图8B中RMSI在时域资源单元Ux的冗余版本RVx与图8A一致。以RMSI TTI为160ms，RMSI发送周期为40ms为例，RMSI在一个TTI中可以在无线帧{x＝0，x＝4，x＝8，x＝12}上传输，且在x＝0的无线帧上RMSI的PDSCH的RV＝0，在x＝4的无线帧上RMSI的PDSCH的RV＝2，在x＝8的无线帧上RMSI的PDSCH的RV＝3，在x＝12的无线帧上RMSI的PDSCH的RV＝1，共采用了四种RV完成一个TTI内的RMSI收发。以RMSI TTI为160ms，RMSI发送周期为80ms为例，RMSI在一个TTI中可以在无线帧{x＝0，x＝8}上传输，且在x＝0的无线帧上RMSI的PDSCH的RV＝0，在x＝8的无线帧上RMSI的PDSCH的RV＝3，共采用了两种RV完成一个TTI内的RMSI收发。与图7B相比，图8B对应的方案能够实现在相同RMSI发送周期的情况下，在一个TTI内使用更多的冗余版本进行RMSI的收发，能够在RMSI TTI内增加一个波束上收发RMSI的RV，从而能够提供更大的频选性增益。
602部分的第五种示例中，M还可以根据系统消息(例如RMSI)的发送周期确定。以Ux的单位为无线帧、RMSI的发送周期T1＝10ms为例，则x1＝x/M＝x/1；以Ux的单位为无线帧、RMSI的发送周期T1＝20ms为例，则x1＝x/M＝x/2；以Ux的单位为无线帧、RMSI的发送周期T1＝40ms为例，则x1＝x/M＝x/4；以Ux的单位为无线帧、RMSI的发送周期T1＝80ms为例，则x1＝x/M＝x/8，或者x1＝x/M＝x/4；以Ux的单位为无线帧、RMSI的发送周期T1＝80ms为例，则x1＝x/M＝x/8，或者x1＝x/M＝x/4；以Ux的单位为无线帧、RMSI的发送周期T1＝160ms为例，则x1＝x/M＝x/16，或者x1＝x/M＝x/8，或者x1＝x/M＝x/4。可以 理解的是，若Ux的单位以时隙为例，则M需要根据系统消息(例如RMSI)的发送周期和子载波间隔参数确定。以Ux的单位为时隙、RMSI的发送周期T1＝5ms、子载波间隔为15KHz为例，则x1＝x/M＝x/5；以Ux的单位为时隙、RMSI的发送周期T1＝5ms、子载波间隔为30KHz为例，则x1＝x/M＝x/10；以Ux的单位为时隙、RMSI的发送周期T1＝5ms、子载波间隔为60KHz为例，则x1＝x/M＝x/20；以Ux的单位为时隙、RMSI的发送周期T1＝5ms、子载波间隔为120KHz为例，则x1＝x/M＝x/40；以Ux的单位为时隙、RMSI的发送周期T1＝10ms、子载波间隔为15KHz为例，则x1＝x/M＝x/10；以Ux的单位为时隙、RMSI的发送周期T1＝10ms、子载波间隔为30KHz为例，则x1＝x/M＝x/20。604部分、605部分和606部分与前述类似，在此不再赘述。当Ux的单位为时隙的时候，M的值也可以使用M1*2 u表示，其中子载波间隔为15KHz，30KHz，60KHz，120KHz的时候，u分别对应0、1、2、3。M1的值可以为5，也可以为10。
602部分的第六种示例中，不同的系统消息的发送周期也可以采用相同的参数M。例如，以RMSI的发送周期包含{5ms，10ms，20ms、40ms、80ms和160ms}为例。在一种可能的实施方式下，全部RMSI的发送周期对应相同的参数M；以M＝4为例，则无论RMSI的发送周期为{5ms，10ms，20ms、40ms、80ms和160ms}中的哪一个，M的取值都为4。在另一种可能的实施方式下，部分RMSI的发送周期对应相同的参数M；例如，RMSI的发送周期为{20ms、40ms}时采用相同的M＝4，RMSI的发送周期为{80ms、160ms}时采用相同的M＝2。604部分、605部分和606部分与前述类似，在此不再赘述。
602部分的第七种示例中，不同的系统消息与同步信号块的复用方式下的参数M可以分别定义或配置(指示)。所述不同的系统消息与同步信号块的复用方式包含时分复用和频分复用。以系统消息为RMSI为例，RMSI与同步信号块的复用方式包含时分复用和频分复用，则可以为RMSI与同步信号块时分复用和RMSI与同步信号块频分复用时RMSI的传输分别定义或配置(指示)各自的参数M。例如，RMSI与同步信号块时分复用时RMSI的传输采用的M可以定义为M＝2，RMSI与同步信号块频分复用时RMSI的传输采用的M可以定义为M＝4。再例如，RMSI与同步信号块时分复用时RMSI的传输采用的M可以定义为M＝2，RMSI与同步信号块时分复用时RMSI的传输采用的M的值可以根据RMSI的发送周期确定。再例如，RMSI与同步信号块时分复用时RMSI的传输采用的M可以定义为M＝4，RMSI与同步信号块频分复用时RMSI的传输采用的M或RMSI的发送周期可以由DCI配置或指示。再例如，RMSI与同步信号块时分复用时RMSI的传输采用的M或RMSI的发送周期可以由DCI配置或指示，RMSI与同步信号块时分复用时RMSI的传输采用的M可以定义为M＝4。再例如，RMSI与同步信号块时分复用时RMSI的传输采用的M或RMSI的发送周期可以由DCI配置或指示，RMSI与同步信号块时分复用时RMSI的传输采用的M可以根据RMSI的发送周期确定。604部分、605部分和606部分与前述类似，在此不再赘述。需要说明的是，当使用DCI配置或指示M取值或RMSI的发送周期时，可以复用DCI中的部分字段，例如复用下述字段中的一个或多个，{字段Redundancy version，字段HARQ process number，字段TPC command for PUCCH，字段Frequency domain resource assignment，字段ARI(ACK/NAK Resource Index)，字段ARI HARQ timing indicator，字段Carrier indicator，字段BWP indicator，字段Time-domain PDSCH resources，字段VRB-to-PRB mapping，字段Reserved resource set on/off，字段Bundling size indicator，字段Modulation and coding scheme，second CW， 字段New data indicator，second CW，字段Redundancy version，second CW，字段CBGFI，字段CBGTI，字段Downlink Assignment Index，字段Antenna port(s)，字段TCI(Transmission Configuration Indication)}。需要说明的是，本申请实施例在604部分中并不限定对x1的取整方式。优选地，对x1采用下取整的方式。
可以理解的是，本申请实施例在602部分中并不限定M的具体取值。优选地，所述M的取值可以为{1、2、4、5、8、16}中的任意一个，也可以根据系统消息的发送周期确定。可以理解的是，除了所述优选值以外，M还可以取其他正实数，例如M还可以是系统消息子窗口包含的时域资源单元数量。
本申请实施例提供的系统消息冗余版本确定方法及装置，通过增加能够承载系统消息有效RV的时域资源单元数量，从而解决了某些时域资源单元上的波束无法支持系统消息的有效RV进而承载系统消息波束数量减少的问题，从而提高了系统消息的覆盖范围，并且在部分实施方式下能够在系统消息窗口或系统消息子窗口内增加一个波束上收发系统消息的RV，为系统消息的接收提供更大的频选性增益。
可选的，对于601部分中的M，可以不采用602部分描述的方式确定，而是参考图6中的603部分，即M可以根据实际传输的同步信号块数量N确定。例如，所述M还可以由通信设备根据{实际传输的同步信号块数量N，系统消息的子窗口包含的时域资源单元数量D}中的至少一项确定。所述实际传输的同步信号块数量N可以由网络设备通知终端设备，例如在NR中，所述实际传输的同步信号块数量N由网络设备通过RMSI通知给终端设备。所述D也可以表示一个预定义的常数，或是多个预定义常数中的任意一个。需要说明的是，采用603部分时，图6示意的本申请实施方案也可以理解为通信设备根据{实际传输的同步信号块数量N，系统消息的子窗口包含的时域资源单元数量D}中的至少一项确定所述系统消息在时域资源单元Ux的冗余版本RVx。可以理解的是，603部分中仅示意了N的一种可能含义，例如，N也可以表示可能传输的同步信号块数量。
在603部分的第一种可能的实施方式中，以M＝N*D或M＝n*N*D为例，n表示波束扫描周期的倍数。以所述系统消息为OSI、所述时域资源单元为时隙、OSI的子窗口包含的时隙数量D＝1以及实际传输的同步信号块数量N＝6、n＝1为例，则可以获得M＝6*1＝6、x1＝x/6。可以理解的是，所述实际传输的同步信号块数量N＝6也可以理解为包含有N＝6个波束，一个波束承载一个实际传输的同步信号块。604部分中，所述通信设备对所述参数x1下取整获得参数x2，x2＝floor(x1)＝floor(x/6)。605部分和606部分与前述类似，在此不再赘述。则可以获得所述OSI在时隙Ux的冗余版本为RVx＝(ceil(3/2*(floor(x/6)mod4)))mod 4。
在603部分的第二种可能的实施方式中，以M＝2*N*D为例。以所述系统消息为OSI、所述时域资源单元为时隙、OSI的子窗口包含的时隙数量D＝1以及实际传输的同步信号块数量N＝6为例，则可以获得M＝2*6*1＝12、x1＝x/12。可以理解的是，所述实际传输的同步信号块数量N＝6也可以理解为包含有N＝6个波束，一个波束承载一个实际传输的同步信号块。604部分中，所述通信设备对所述参数x1上取整获得参数x2，x2＝ceil(x1)＝ceil(x/12)。605部分和606部分与前述类似，在此不再赘述。则可以获得所述OSI在时隙Ux的冗余版本为RVx＝(ceil(3/2*(ceil(x/12)mod 4)))mod 4。
图9A给出了依据上述示例得到的OSI在时隙Ux的冗余版本RVx示意，以32个时隙(时隙0-时隙31)为例，且以{时隙8、时隙9、时隙18、时隙19、时隙28、时隙29} 为上行时隙，其余时隙为下行时隙且OSI承载于下行时隙为例。图9A进一步以4轮波束扫描为例，一轮波束扫描包含N＝6个波束，一个波束在一个下行时隙上传输，OSI可以承载在6个波束中的一个或多个上。图9A进一步以OSI承载于垂直向上的波束为例，示意了在4轮波束扫描中OSI发送的时隙及其使用的RV。示意的承载于垂直向上波束的OSI在{x＝0，x＝6，x＝14，x＝22}时隙上，分别使用对应的冗余版本为{RVx＝0，RVx＝2，RVx＝3，RVx＝1}。
需要说明的是，OSI也可以承载于其他波束上。可以理解的是，OSI一般会承载在信道条件较好的波束上发送。例如NR系统的网络设备可以在同步过程中通过同步信号块的发送以及终端设备的反馈，确定与所述终端设备间在哪条波束上的信道条件相对较好，由此为依据将OSI承载在相应的波束上。可以理解的是，所述终端设备的反馈可以是由所述终端设备直接显式向网络设备反馈信道条件相对较好的波束标识，也可以通过上行信道(例如随机接入信道)或上行信号(例如探测参考信号)的发送隐式告知网络设备信道条件相对较好的波束。
图9B给出了另一种方法得到的OSI在时隙Ux的冗余版本RVx示意，其中RVx的确定方式为RVx＝(ceil(3/2*(x mod 4)))mod 4。图9B的其他内容与图9A类似。图9B中示意的承载于垂直向上波束的OSI在{x＝0，x＝6，x＝14，x＝22}时隙上，分别使用对应的冗余版本为{RVx＝0，RVx＝3，RVx＝3，RVx＝3}。
通过对比可以看出，图9A与图9B提供的方法相比，能够使用更多的冗余版本进行OSI的收发，能够在系统消息窗口或系统消息子窗口内增加一个波束上收发OSI的RV，从而能够提供更大的频选性增益。
需要说明的是，在603部分中，N还可能有其他取值，例如N＝2、4、8等；D还可能有其他取值，例如D＝0.5、2、4等。
可选地，图9C给出了在另一种时域资源单元编号或时域资源单元索引的情况下OSI在时隙Ux的冗余版本RVx示意，以32个时隙(时隙U0-时隙U31)为例，且以{时隙U8、时隙U9、时隙U18、时隙U19、时隙U28、时隙U29}为上行时隙，其余时隙为下行时隙且OSI承载于下行时隙为例。图9C中的x仅标识可以承载OSI的时隙，标有‘-’的时隙无法承载OSI。图9C仍以4轮波束扫描为例，一轮波束扫描包含N＝6个波束，一个波束在一个下行时隙上传输，OSI可以承载在6个波束中的一个或多个上。图9C进一步以OSI承载于垂直向上的波束为例，示意了在4轮波束扫描中OSI发送的时隙及其使用的RV。示意的承载于垂直向上波束的OSI在{x＝0，x＝6，x＝12，x＝18}时隙上，分别使用对应的冗余版本为{RVx＝0，RVx＝2，RVx＝3，RVx＝1}。
在603部分的另一种可能的实施方法中，还可以根据其他方法获得M。例如可以采用M＝N*D+F获得M。图9D给出了采用M＝N*D+F获得M时的一种OSI在时隙Ux的冗余版本RVx示意，其他条件与图9A相同。图9D中以F＝2为例，则M＝N*D+F＝6*1+2＝8。604部分、605部分和606部分与前述类似，在此不再赘述，则可以获得如图9D所示的OSI在时隙Ux的冗余版本RVx示意。与图9A相比，图9D中每一轮波束扫描包含的时域资源单元数量相同，而图9A中不同轮的波束扫描可能包含不同的时域资源单元数量。本申请实施例通过采用M＝N*D+F获得OSI在时隙Ux的冗余版本RVx，且能够实现相同的一轮波束扫描的时间，从而可以使终端设备更加容易地获得波束扫描的位置，简化终端设备的实现。
需要说明的是，本发明实施例的603部分并不限定上述获得M的方法，例如还可以采用M＝f(N，D)+F获得M。其中f(N，D)可以为f(N，D)＝N*D，或者为f(N，D)＝floor(N*D)，或者为f(N，D)＝ceil(N*D)；F为由网络设备配置的或是预定义的非负整数。所述F还可以由其他方法获得，例如可以采用如下方法中的任意一个获得F：
F＝g(D，N，N_DL，N_UK)*N_UL，
F＝g(D，N，N_DL，N_UK)*(N_UK+N_UL)，
F＝g(D，N，N_DL，N_UK)*N_DU；
其中N_DL为半静态上下行资源分配周期内下行时域资源单元的数量，N_UL为半静态上下行资源分配周期内上行时域资源单元的数量，N_DU为半静态上下行资源分配周期内时域资源单元的数量，N_UK为半静态上下行资源分配周期内灵活时域资源单元的数量。其中g(D，N，N_DL，N_UK)可以采用下列方法中的任意一个获得：
f(N，D)/R，floor(f(N，D)/R)，ceil(f(N，D)/R)，其中R的取值为N_DL、N_UK、N_UK+N_DL中的任意一个。
可以理解的是，本申请实施例在605部分中还可以根据其他方法获得x3，例如可以采用下列方法中的任意一个：
x3＝x mod K，x3＝floor(x/ceil(D))mod K，x3＝(x+z)mod K，其中z可以表示冗余版本的偏移值，该偏移值可以是系统消息窗口内的波束扫描周期的索引，也可以是其他常数。
本申请实施例提供的系统消息冗余版本确定方法及装置，通过增加能够承载系统消息有效RV的时域资源单元数量，从而解决了某些时域资源单元上的波束无法支持系统消息的有效RV进而承载系统消息波束数量减少的问题，从而提高了系统消息的覆盖范围，并且在部分实施方式下能够在系统消息窗口或系统消息子窗口内增加一个波束上收发系统消息的RV，为系统消息的接收提供更大的频选性增益。
为了减少终端设备在接收系统消息时的盲检次数，降低终端设备的功耗和复杂度，本申请提供确定至少一个时域资源单元Ux的方法。可以理解，该方法也可以在图4的401部分中实施。在一种可能的实施方式下，所述通信设备可以根据同步信号块数量N确定承载所述系统消息的时域资源单元Ux；所述同步信号块可以是实际传输的同步信号块，也可以是可能传输的同步信号块。进一步地，在采用波束扫描的情况下，所述时域资源单元Ux包含所述系统消息在其一轮波束扫描(也可以理解为一个波束扫描周期)内的起始时域资源单元，为方便表述，将所述系统消息在第y轮波束扫描中的起始时域资源单元标识为xy0。所述起始时域资源单元xy0可以理解为在第y轮波束扫描中所述系统消息的PDCCH的第一个PDCCH时机的起始时域资源单元，也可以理解为在第y轮波束扫描中所述系统消息的PDCCH由第一个同步信号块关联或对应的PDCCH时机的起始时域资源单元。
例如在图9A中给出了一种可能的实施方式，以OSI进行4轮波束扫描、一轮波束扫描包含N＝6个波束、第一轮波束扫描的起始时域资源单元为时隙x10＝0为例。则OSI在第二轮波束扫描的起始时域资源单元为时隙x20＝x10+N+j1＝0+6+0＝6，其中，j1为第一轮波束扫描的时间段内不能承载OSI的时域资源单元数量；OSI在第三轮波束扫描的起始时域资源单元为时隙x30＝x20+N+j2＝6+6+2＝14，其中j1为第二轮波束扫描的时间段内不能承载OSI的时域资源单元数量；OSI在第四轮波束扫描的起始时域资源单元为时隙x40＝x30+N+j3＝14+6+2＝22，其中j3为第三轮波束扫描的时间段内不能承载OSI的时域资源单元数量。
例如在图9C中给出了另一种可能的实施方式，以OSI进行4轮波束扫描、一轮波束扫描包含N＝6个波束、第一轮波束扫描的起始时域资源单元为时隙x10＝0为例。图9C中的x仅标识可以承载OSI的时隙，标有‘-’的时隙无法承载OSI。则OSI在第二轮波束扫描的起始时域资源单元为时隙x20＝x10+N＝0+6＝6；OSI在第三轮波束扫描的起始时域资源单元为时隙x30＝x20+N＝6+6＝12；OSI在第四轮波束扫描的起始时域资源单元为时隙x40＝x30+N＝12+6＝18。
可以理解的的是，第一轮波束扫描的起始时域资源单元还可以是x10＝x0+Offset，其中x0可以理解为参考点，其可以是一个非负整数；Offset可以理解为第一轮波束扫描的起始时域资源单元相对上述参考点的偏置，其可以是一个非负整数。x10也可以理解为系统消息窗口的起始时域资源单元或系统消息窗口内第一轮波束扫描的起始时域资源单元，对应地，Offset也可以理解为系统消息窗口的起始时域资源单元相对上述参考点的偏置。在上述x10＝0的例子中，可以理解为x0＝0且Offset＝0，本发明实施例并不限制x0和Offset的其他取值和单位，例如Offset还可以取5ms。
需要说明的是，本发明实施例并不限定根据所述实际传输的同步信号块数量N确定所述时域资源单元Ux的具体方法。例如还可以用下述方法中的任意一种获得系统消息在第y轮波束扫描中的起始时域资源单元索引xy0：
h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod N_DU+Offset，
h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod N_DL+Offset，
h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod(N_DL+N_UK)+Offset，
(h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod N_DU+Offset)mod N_frame，
(h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod N_DL+Offset)mod N_frame，
(h(y，D，N，N_DL，N_UK)*N_DU+p(y，D，N，N_DL，N_UK)mod(N_DL+N_UK)+Offset)mod N_frame，
y*M+Offset，
(y*M+Offset)mod N_frame；
其中，N_frame可以为一个无线帧内的时隙数目或者子帧数目。Offset为可选参数；可选地，以Offset的单位为时隙为例，则所述Offset可以是0-80中的任一整数；可选地，以Offset的单位为ms为例，则所述Offset可以是0-10中的任一整数，也可以是0-10中小数点后为1位的任一实数。M可以通过602部分或603部分中描述的方法获得，此处不再赘述。
上述方法中的h(y，D，N，N_DL，N_UK)和p(y，D，N，N_DL，N_UK)可以采用如下任意一种方法获得，且h(y，D，N，N_DL，N_UK)和p(y，D，N，N_DL，N_UK)可以采用相同或不同的方法获得：
y*f(D，N)/R，floor(y*f(D，N))/R，ceil(y*f(D，N))/R，floor(y*D)*N/R，ceil(y*D)*N/R，floor(floor(y*f(D，N))/R)，floor(ceil(y*f(D，N))/R)，floor(y*f(D，N)/R)，floor(floor(y*D)*N/R)，floor(ceil(y*D)*N/R)，ceil(floor(y*f(D，N))/R)，ceil(ceil(y*f(D，N))/R)，ceil(y*f(D，N)/R)，ceil(floor(y*D)*N/R)，ceil(ceil(y*D)*N/R)；其中R的取值为N_DL、N_UK、N_UK+N_DL中的任意一个。
在图4的401部分中，通信设备要确定至少一个时域资源单元Ux。在一种可能的实施方式下，所述通信设备可以根据同步信号块数量N确定承载所述系统消息的时域资源单元Ux；所述同步信号块可以是实际传输的同步信号块，也可以是可能传输的同步信号块。进一步地，在采用波束扫描的情况下，所述时域资源单元Ux包含所述系统消息在其一轮波束扫描(也可以理解为一个波束扫描周期)内的至少一个时域资源单元，为方便表述，将所述系统消息在第y轮波束扫描中的至少一个时域资源单元标识为xyj。其中时域资源单元xy0表示所述系统消息在第y轮波束扫描中的起始时域资源单元，其获得方法可以参考上述描述，此处不再赘述；所述时域资源单元xyj(j为正整数)表示所述系统消息在第y轮波束扫描中除起始时域资源单元xy0以外的第j个时域资源单元，j也可以为实际发送或可能发送的SS/PBCH block的索引，也可以为系统消息的索引。所述时域资源单元xyj可以理解为在第y轮波束扫描中所述系统消息的PDCCH除第一个PDCCH时机以外的PDCCH时机的起始时域资源单元，也可以理解为在第y轮波束扫描中所述系统消息的PDCCH除由第一个同步信号块以外的同步信号块关联或对应的PDCCH时机的起始时域资源单元。所述xyj可以采用如下任意一种方法获得：
(xy0+f(j，D))mod N_frame，(xy0+f(j，D)+Oj)mod N_frame，floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod N_DU，(floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod N_DU)mod N_frame，floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod R，(floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod R)mod N_frame，floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod N_DU+Offset，(floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod N_DU+Offset)mod N_frame，floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod R+Offset，(floor(q(y，M，j，D)/R)*N_DU+r(y，M，j，D)mod R+Offset)mod N_frame
其中，M可通过602部分或603部分描述的方法获得，此处不再赘述。q(y，M，j，D)和r(y，M，j，D)可以采用如下任意一种方法获得，且q(y，M，j，D)和r(y，M，j，D)可以采用相同或不同的方法获得：
y*M+f(j，D)，floor(y*M+f(j，D))，ceil(y*M+f(j，D))。
其中，Oj可以表示所述系统消息在第y轮波束扫描中除起始时域资源单元xy0到所述时域资源单元xyj之间的不能传输所述系统消息的时域资源单元数目。Oj可以采用如下任意一种方法获得：
Oj＝floor(f(j，M)/R)*S，Oj＝ceil(f(j，M)/R)*S，Oj＝floor((xy0mod N_DU+f(j，D))/N_DL)*N_UL，Oj＝ceil((xy0mod N_DU+f(j，D))/N_DL)*N_UL；其中S的取值为N_UL、N_UK、N_UK+N_UL中的任意一个。可以理解的是，Oj可以是必选的参数，也可以是可选的参数。
在另一种可能的实施方式下，所述系统消息采用波束扫描时在第y轮波束扫描中的起始时域资源单元xy0的位置是固定的，可以理解为所述系统消息采用波束扫描时在一轮扫描中的起始时域资源单元的位置是预先定义的，例如可以是系统消息窗口或系统消息子窗口的起始位置、中间位置、1/4位置、3/4位置中至少一个或任意一个。
以系统消息窗口的长度为20ms为例，则所述起始位置、中间位置、1/4位置和3/4位置分别为所述系统消息窗口的0ms，5ms，10ms和15ms这4个位置。在一种可能的实施方式中，以预定义这4个位置中的任意一个为例，例如预定义0ms的位置，则所述系统消息在一轮波束扫描中的起始时域资源单元固定为该系统消息窗口第一个时域资源单元。在另一 种可能的实施方式中，以预定义这4个位置中的至少一个为例，例如预定义0ms和10ms两个位置，则终端设备还需要根据其他的配置信息确定应采用0ms和10ms中的哪一个位置；例如，终端设备可以根据实际传输的同步信号块数量、系统消息窗口的长度决定应采用0ms和10ms中的哪一个位置。
在另一种可能的实施方式下，所述系统消息采用波束扫描时在第y轮波束扫描中的起始时域资源单元xy0的位置还可以是由网络设备配置或指示的。所述网络设备可以通过RMSI、OSI、媒体接入控制元素(Media Access Control-Control Element，MAC-CE)、无线资源控制(Radio Resource Control，RRC)信令、下行控制信息(Downlink Control Information，DCI)中的至少一种配置或者指示所述系统消息采用波束扫描时在一轮扫描中的起始时域资源单元的位置。
本申请实施例提供的方法及装置，通过确定系统消息采用波束扫描时在一轮扫描中的至少一个时域资源单元，可以减少终端设备盲检系统消息的次数，从而降低终端设备的功耗和复杂度。
图10为本申请实施例提供的系统消息收发方法的流程图。如图10所示，本实施例的方法可以包括：

所述8个冗余版本可以是预定义的，也可以是由网络配置的。所述8个冗余版本还可以是通过公式计算获得的，所述公式与图6、图7A、图7B、图8A、图8B、图9A、图9C、图9D中的描述类似，仅需改变公式中个别参数的取值，例如将公式中与预定义的RV个数相关的参数置为8，此处不再赘述。
还需要理解的是，图7A、图7B、图8A、图8B、图9A、图9C、图9D均以公式计算的方式为例获得时域资源单元上的冗余版本，本发明对具体实施例中的冗余版本的获得方式并不做限定，在1001部分中，通信设备还可以采用其他方式获得时域资源单元上的冗余版本。

可以理解的是，不同的系统消息与同步信号块的复用方式下的所述时域资源单元Ux上系统消息的冗余版本RVx可以采用不同的方法(例如预定义、配置、指示等)获得。所述不同的系统消息与同步信号块的复用方式包含时分复用和频分复用。以系统消息为RMSI，且RMSI与同步信号块的复用方式包含时分复用和频分复用为例，一个例子中，RMSI与同步信号块时分复用时RMSI的传输在时域资源单元Ux采用的冗余版本RVx可以根据上述图4、图6中描述的方法获得，RMSI与同步信号块频分复用时RMSI的传输在时域资源单元Ux采用的冗余版本RVx可以由DCI配置或指示。另一个例子中，RMSI与同步信号块时分复用时RMSI的传输在时域资源单元Ux采用的冗余版本RVx可以由DCI配置或指示，RMSI与同步信号块频分复用时RMSI的传输在时域资源单元Ux采用的冗余版本RVx可以根据上述图4、图6中描述的方法获得。需要说明的是，当使用DCI配置或指示RVx时，可以复用DCI中的部分字段，例如复用下述字段中的至少一个{字段Redundancy version，字段HARQ process number，字段TPC command for PUCCH，字段ARI(ACK/NAK Resource Index)，字段Frequency domain resource assignment，字段ARI HARQ timing indicator，字段Carrier indicator，字段BWP indicator，字段Time-domain PDSCH resources，字段VRB-to-PRB mapping，字段Reserved resource set on/off，字段Bundling size indicator，字段Modulation and coding scheme，second CW，字段New data indicator，second CW，字段Redundancy version，second CW，字段CBGFI，字段CBGTI，字段Downlink Assignment Index，字段Antenna port(s)，字段TCI(Transmission Configuration Indication)}。可以理解的是，网络设备可以同时采用上述图4、图6中描述的方法和在DCI中配置RVx的方法；当终端设备接收到的系统消息的DCI中RVx与上述图4、图6中描述的方法不相同的时候，可以采用DCI中指示的RVx为准，也可以采用上述图4、图6中描述的方法为准。网络设备也可以将采用上述图4、图6中描述的方法设为默认的方法，如果DCI中配置了RVx，则终端设备以DCI配置为准。网络设备也可以在DCI中携带DCI中配置RVx和用上述图4、图6中描述的方法，可以复用上面的任意字段进行指示。
在1002部分中，通信设备可以根据图7B、图8B、图9A、图9C示例和描述的方法，使用所述冗余版本，在所述至少两个在时域上连续的时域资源单元中的至少一个时域资源单元上接收或发送所述系统消息。详细内容参见图7B、图8B、图9A、图9C对应的描述，此处不再赘述。
