下面结合具体例子,以第一至第三终端装置和网络装置为例,更加详细地描述本申请的实施例。
图7为本申请实施例提供的一种控制信息的传输方法、第一至第四终端装置、网络装置及系统。如图3所示,第一终端装置包括发送单元31、处理单元32以及接收单元33,其中,发送单元31与接收单元33可以由收发单元代替。如图4所示,第二终端装置包括发送单元41、处理单元42以及接收单元43,其中,发送单元41与接收单元43可以由收发单元代替。如图5所示,第三终端装置包括发送单元51、处理单元52以及接收单元53,其中,发送单元51与接收单元53可以由收发单元代替。如图6所示,网络装置包括发送单元61、处理单元62以及接收单元63,发送单元61和接收单元63可以由收发单元代替。
当第一至第三终端装置为车载模块、车载模组或者用户设备时,当网络装置为基站时,处理单元32至处理单元62可以为处理器,发送单元31至发送单元61、接收单元33至接收单元63可以为收发器,发送单元31至发送单元61可以为发射器,接收单元33至接收单元63可以为接收器,此收发器、发射器或接收器可以为射频电路,当第一至第二终端装置或网络装置包含存储单元时,该存储单元用于存储计算机指令,该处理器与存储器通信连接,处理器执行存储器存储的计算机指令,使第一至第二终端装置或网络装置执行图7实施例涉及的方法。其中,处理器可以是一个通用中央处理器(CPU),微处理器,特定应用集成电路(Application Specific Intergrated Circuit,ASIC)。
当第一至第三终端装置或网络装置为芯片时,所述处理单元32至处理单元62例如可以是处理器,发送单元31至发送单元61可以是输出接口、管脚或电路等,接收单元33至接收单元63可以是输入接口、管脚或电路等,所述收发单元例如可以是输入/输出接口、管脚或电路等。该处理单元可执行存储单元存储的计算机执行指令,以使该第一至第二终端装置内或网络装置内的芯片执行图7所涉及的方法。可选地,所述存储单元为所述芯片内的存储单元,如寄存器、缓存等,所述存储单元还可以是所述终端内的位于所述芯片外部的存储单元,如只读存储器(Read Only Memory,ROM)或可存储静态信息和指令的其 他类型的静态存储设备,随机存取存储器(Random Access Memory,RAM)等。
图7实施例所涉及的侧行同步信号突发集的配置信息的发送和接收方法的步骤包括:
步骤71,网络装置的处理单元62确定配置信息,此配置信息可以由网络装置发送给其所覆盖的小区内的终端装置,此配置信息也可以由网络装置发送给第一终端装置,再由第一终端装置发送给其周边的终端装置(例如,第二终端装置和第三终端装置)。配置信息用于配置终端装置之间进行同步的侧行同步信号突发集的传输参数。
配置信息包括侧行同步信号突发集时域指示信息、侧行同步信号突发集频域指示信息、侧行同步信号突发集周期指示信息或侧行同步信号突发集周期复用指示信息中的至少一个信息,所述侧行同步信号突发集(burst set)包括至少一个同步信号块(Synchronization Signal Block,SSB),所述同步信号块包括主同步信号、辅同步信号和广播信息,所述侧行同步信号突发集时域指示信息用于指示侧行同步信号突发集的时域资源位置,所述侧行同步信号突发集频域指示信息用于指示侧行同步信号突发集的频域资源位置,所述侧行同步信号突发集周期指示信息用于指示侧行同步信号突发集的周期,所述侧行同步信号突发集周期复用指示信息用于指示侧行同步信号突发集的周期是否复用所述第一终端装置所在小区的同步信号突发集的周期。
侧行同步信号突发集包括至少一个侧行同步信号块,所述侧行同步信号块包括主同步信号、辅同步信号和广播信息,此广播信息具体可以称为物理广播信道(Physical Broadcast Channel,PBCH),主同步信号和辅同步信号主要作用是帮助接收端终端装置识别发送端终端装置,以及接收端终端装置与发送端终端装置进行同步,广播信息则包含了最基本的系统信息,例如系统帧号、时隙号或微时隙号、帧内或时隙内定时信息等。同步信号块可以占用x个符号,x为大于或等于2的正整数,x的取值可以有协议预定义,也可以由网络装置确定。例如图8所示为一个同步信号块的结构,此同步信号块占用了符号n至符号n+3的共4个符号,主同步信号位于符号n,辅同步信号位于符号n+2,广播信息位于符号n至符号n+3内除所述主同步信号和辅同步信号之外的全部或部分资源上,例如在图8中,广播信息位于符号n+1、符号n+3以及符号n+2上除所述辅同步信号之外的资源上。
为了支持多波束特性,侧行同步信号突发集为包含一个或多个侧行同步信号块的时间窗或一段时间,终端装置可以采用不同的波束发送侧行同步信号突发集中包含的多个不同的侧行同步信号块,侧行同步信号突发集在时域上可以占用y毫秒,y为正整数,此y毫秒可以为协议预定义的或者由网络装置配置的。侧行同步信号突发集所包含的侧行同步信号块的最大数量L与子载波间隔(Subcarrier Space,SCS)具有对应关系,此对应关系可以由协议预定义,此对应关系可以为一个表格,不同的子载波间隔对应一个所述最大数量L,此表格可以存储于网络装置或者终端装置内,由网络装置或终端装置根据子载波间隔通过查表获得对应的最大数量L。可选的,所述侧行同步信号突发集所包含的侧行同步信号块的最大数量L也可以由网络装置或者终端装置根据子载波间隔确定。终端设备会周期性地发送侧行同步信号突发集,此侧行同步信号突发集中实际包含的侧行同步信号块的数量小于等于所述最大数量L。
图9以侧行同步信号突发集所占用的时间为5毫秒为例说明侧行同步信号突发集的结构,在图9中,当SCS<3GHz时,1个侧行同步信号突发集包含的侧行同步信号块的最大数 量为4,终端装置在被调度或者自主选择其中的3个位置发送侧行同步信号块,可选的,终端装置也可以在侧行同步信号突发集的5毫秒内发送4个侧行同步信号块,即以SCS所对应的最大数量来发送侧行同步信号块。当3GHz≤SCS<6GHz时,1个侧行同步信号突发集包含的侧行同步信号块的最大数量为8,终端装置在被调度或者自主选择其中的5个位置发送侧行同步信号块,可选的,终端装置也可以在侧行同步信号突发集的5毫秒内发送8个侧行同步信号块,即以SCS所对应的最大数量来发送侧行同步信号块。当6GHz≤SCS≤52.6GHz时,1个侧行同步信号突发集包含的侧行同步信号块的最大数量为64,终端装置在被调度或者自主选择其中的32个位置发送侧行同步信号块,可选的,终端装置也可以在侧行同步信号突发集的5毫秒内发送64个侧行同步信号块,即以SCS所对应的最大数量来发送侧行同步信号块。
步骤72,网络装置的发送单元61向第一终端装置发送配置信息,第一终端装置的接收单元33从所述网络装置接收所述配置信息。
步骤73,第一终端装置的发送单元31向其周边的终端装置,例如,第二终端装置和/或第三终端装置发送从网路装置接收的配置信息。由此,网络装置确定的传输侧行同步信号突发集的配置信息通过第一终端装置发送给第二终端装置和第三终端装置的方式使第一至第三终端装置均获得此配置信息,然后,第一终端装置会根据此配置信息来发送侧行同步信号突发集。在步骤73中,第一终端装置可以通过侧行控制信息(Sidelink Control Information,SCI)将所述配置信息发送给第二终端装置和/或第三终端装置。
可选的,网络装置的发送单元61除了在步骤72中将配置信息发送给第一终端装置,网络装置的发送单元61还可以在步骤721中向第二终端装置以及第三终端装置发送所述配置信息,当然,步骤721不是必须的。由此,网络装置所确定的传输侧行同步信号突发集的配置信息会通过步骤72以及步骤721由网络装置发送给第一至第三终端装置,使第一至第三终端装置均获得此配置信息,然后,第一终端装置会根据此配置信息来发送侧行同步信号突发集。当网络装置在步骤721中向第二终端装置和第三终端装置发送了所述配置信息的前提下,步骤73可以省略也可以保留。
在步骤72或步骤721中,网络装置可以通过系统消息(System Information Block,SIB)或专用无线资源控制信令来传输配置(dedicated Radio Resource Control,dedicated RRC)信息,即网络装置向第一终端装置、第二终端装置和/或第三终端装置发送系统消息或专用无线资源控制信令,而所述系统消息或专用无线资源控制信令包含所述配置信息。系统消息是小区特定的,即系统消息可以被网络装置覆盖的小区内的所有终端装置接收及解码。专用无线资源控制信令是终端装置特定或用户设备特定的,即对于某一专用无线资源控制信令,只有对应的终端装置才能够接收及解码。通过专用无线资源控制信令来进行配置信息的指示,则小区内的不同的终端装置可以灵活的采用不同的侧行同步信号突发集配置,由此提高侧行同步的灵活性。
在步骤72或步骤721中,网络装置还可以通过系统消息和专用无线资源控制信令来传输配置信息,即网络装置向第一终端装置、第二终端装置和/或第三终端装置发送系统消息和专用无线资源控制信令。所述系统消息包含所述侧行同步信号突发集周期指示信息或侧行同步信号突发集周期复用指示信息中的至少一个信息,所述专用无线资源控制信令包含所述侧行同步信号突发集时域指示信息、侧行同步信号突发集频域指示信息中的至少 一个信息,所述专用无线资源控制信令为终端装置特定信令。例如,网络装置通过系统消息将侧行同步信号突发集周期指示信息或侧行同步信号突发集周期复用指示信息中的至少一个信息发送给第一至第三终端装置,由此第一至第三终端装置均会根据系统消息所包含的侧行同步信号突发集周期指示信息或侧行同步信号突发集周期复用指示信息中的至少一个信息确定侧行同步信号突发集的发送周期。网络装置还会向第一至第三终端装置分别发送专用无线资源控制信令,所述专用无线资源控制信令包含所述侧行同步信号突发集时域指示信息、侧行同步信号突发集频域指示信息中的至少一个信息,由此,第一至第三终端装置会分别根据网络装置发送的与其对应的专用无线资源控制信令获取与第一至第三终端装置分别对应的侧行同步信号突发集时域信息和/或频域信息。
步骤74,第一终端装置的发送单元31根据所述配置信息向第二终端装置和/或第三终端装置发送侧行同步信号突发集,第二终端装置的接收单元43根据所述配置信息从所述第一终端装置接收所述侧行同步信号突发集,第三终端装置的接收单元53根据所述配置信息从所述第一终端装置接收所述侧行同步信号突发集。由此,第二终端装置和第三终端装置可以根据所述侧行同步信号突发集与所述第一终端装置进行同步。
侧行同步信号突发集的发送周期可以由侧行同步信号突发集周期复用指示信息或侧行同步信号突发集周期指示信息指示。
当所述配置信息包括侧行同步信号突发集周期复用指示信息时,即可以通过侧行同步信号突发集周期复用指示信息来指示侧行同步信号突发集的发送周期。侧行同步信号突发集周期复用指示信息可以为1比特的信息,例如,其取值为1时指示复用所述第一终端装置所在小区的同步信号突发集的周期,其取值为0时指示不复用所述第一终端装置所在小区的同步信号突发集的周期。所述侧行同步信号突发集周期复用指示信息指示所述侧行同步信号突发集的周期复用所述第一终端装置所在小区的同步信号突发集的周期。第一终端装置为所述网络装置所覆盖的小区内的终端装置,此网络装置会周期性地发送同步信号突发集用于其覆盖小区内的终端装置与其进行同步,则第一终端装置待发送的侧行同步信号突发集的发送周期可以由侧行同步信号突发集周期复用指示信息指示,是否与所述网络装置周期性地发送的同步信号突发集的发送周期相同,如果相同,则侧行同步信号突发集的发送周期复用所述所述网络装置周期性地发送的同步信号突发集的发送周期。此时,所述第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述第一终端装置所在小区的同步信号突发集的周期和预定义的所述侧行同步信号突发集的时频资源位置向所述第二终端装置发送所述侧行同步信号突发集。
可选的,配置信息除包含侧行同步信号突发集周期复用指示信息,还包括侧行同步信号突发集时域指示信息,所述第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述第一终端装置所在小区的同步信号突发集的周期、所述侧行同步信号突发集时域指示信息所指示的所述侧行同步信号突发集的时域资源位置和预定义的所述侧行同步信号突发集的频域资源位置向所述第二终端装置发送所述侧行同步信号突发集。本申请中,侧行同步信号突发集时域指示信息可以指示侧行同步信号突发集相对于无线帧的起始位置的时域偏移量,或指示侧行同步信号突发集相对于当前子帧或时隙的起始位置的时域偏移量,或指示侧行同步信号突发集所包含的侧行同步信号块在子帧或时隙内或侧行同步信号突发集内的时域位置映射图样(pattern), 或指示侧行同步信号突发集在子帧或时隙内的起始时域位置。
可选的,配置信息除包含侧行同步信号突发集周期复用指示信息,还包括侧行同步信号突发集频域指示信息,所述第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述第一终端装置所在小区的同步信号突发集的周期、所述侧行同步信号突发集频域指示信息所指示的所述侧行同步信号突发集的频域资源位置和预定义的所述侧行同步信号突发集的时域资源位置向所述第二终端装置发送所述侧行同步信号突发集。本申请中,侧行同步信号突发集频域指示信息可以指示侧行同步信号突发集的中心频点,或指示侧行同步信号突发集的频率范围,或指示侧行同步信号突发集相对于小区同步信号突发集的频域偏移量,或指示侧行同步信号突发集相对于终端装置的部分带宽(bandwidth part,BWP)的偏移量。
可选的,配置信息除包含侧行同步信号突发集周期复用指示信息,还包括侧行同步信号突发集时域指示信息和侧行同步信号突发集频域指示信息,所述第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述第一终端装置所在小区的同步信号突发集的周期、所述侧行同步信号突发集时域指示信息所指示的所述侧行同步信号突发集的时域资源位置和所述侧行同步信号突发集频域指示信息所指示的所述侧行同步信号突发集的频域资源位置向所述第二终端装置发送所述侧行同步信号突发集。
当所述配置信息包括侧行同步信号突发集周期指示信息时,即可以通过侧行同步信号突发集周期指示信息来直接指示侧行同步信号突发集的发送周期。侧行同步信号突发集周期指示信息可以为q个比特,q为正整数,由此q个比特来指示侧行同步信号突发集的发送周期。第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述侧行同步信号突发集周期指示信息所指示的所述侧行同步信号突发集的周期和预定义的所述侧行同步信号突发集的时频资源位置向所述第二终端装置发送所述侧行同步信号突发集。
可选的,配置信息包括侧行同步信号突发集周期指示信息和侧行同步信号突发集时域指示信息,所述第一终端装置根据所述配置信息向第二终端装置发送所述侧行同步信号突发集包括:所述第一终端装置根据所述侧行同步信号突发集周期指示信息所指示的所述侧行同步信号突发集的周期、所述侧行同步信号突发集时域指示信息所指示的所述侧行同步信号突发集的时域资源位置和预定义的所述侧行同步信号突发集的频域资源位置向所述第二终端装置发送所述侧行同步信号突发集。

当配置信息中同时包含侧行同步信号突发集周期复用指示信息和侧行同步信号突发集周期指示信息时,侧行同步信号突发集的发送周期可以由侧行同步信号突发集周期指示信息指示,也可以由侧行同步信号突发集周期复用指示信息指示,当然,还可以在配置信息中包含一个优先级信息,终端装置会根据优先级信息来确定是根据侧行同步信号突发集周期复用指示信息,还是根据侧行同步信号突发集周期指示信息来确定侧行同步信号突发集的发送周期。
通过本申请实施例,第一终端装置根据侧行同步信号突发集的配置信息来确定侧行同步信号突发集的发送周期以及发送资源,避免了以固定的周期或资源来发送侧行同步信号,因此,提高了V2X通信中同步的灵活性。
