本公开涉及无线通信技术,尤其涉及一种系统信息变更指示方法、网络侧设备及终端。
5G(5th Generation)移动通信系统中,为了降低信令开销、提高无线资源利用率、降低基站能耗等,新空口(New Radio,简称NR)提出了将系统信息(System Information,简称SI)分为两大类,一类为最小系统信息(minimum SI),另一类为其他系统信息(other SI),other SI又称为需求系统信息(On-demand SI)。其中,On-demand SI包含除minimum SI以外的所有SI。基站通过广播将minimum SI发送给终端,而On-demand SI是终端基于自身需求向基站请求获取的。
具体地,On-demand SI根据有效范围又可以分为通用SI(Common SI)和小区特定SI(Cell specific SI)。Common SI是多个小区之间共享的SI,需要在这多个小区保持一致;小区特定SI是一个小区范围内特有的SI。
相关技术中的5G之前的通信系统中,如果系统信息发生变化,基站会通过广播或单播的方式将变更后的系统信息发送给终端,但是,对于Common SI来说,会发生系统信息不一致的问题。

本公开实施例中以第一网络侧设备和第二网络侧设备交互协商为例进行说明,第一网络侧设备作为SI发生变化的一方,第二网络侧设备作为接收第一网络侧设备协商指示的一方。具体场景中,可以有多个第二网络侧设备。
图2为本公开一实施例提供的系统信息变更指示方法流程示意图,如图1所示,该方法包括:
S201、第一网络侧设备向第二网络侧设备发送变更指示。该变更指示用于指示系统信息发生变化。
即由第一网络侧设备确定系统信息要变更,进而可以发起与其他基站的协商。
本实施例中,系统信息可以指通用系统信息(Common SI),但不以此为限。
可选地,第一网络侧设备下的小区与第二网络侧设备下的小区共享系统信息,但不局限于此情况。
S202、第一网络侧设备向第一终端发送系统信息变更通知。该系统信息变更通知用于指示SI发生变化。
该第一终端可以标识第一网络侧设备覆盖范围内的终端,可以有一个或多个,即第一网络侧设备会向自己覆盖范围内的终端发送系统信息变更通知。
S203、第二网络侧设备向第二终端发送该系统信息变更通知。
第二网络侧设备收到变更指示后,也会变更系统信息,进而也向自己覆 盖范围内的终端发送系统信息变更通知。类似地,该第二终端标识第二网络侧设备覆盖范围内的终端,可以有一个或多个。
S202和S203可以同步执行,也可以分别执行,本实施例不作限制。
本实施例中,第一网络侧设备向第二网络侧设备发送变更指示,进而第一网络侧设备会向第一终端发送系统信息变更通知,第二网络侧设备也会向第二终端发送系统信息变更通知。实现了系统信息发生变化时多个网络侧设备之间的协商,以保证这些网络侧设备之间的系统信息一致。
进一步地,第一网络侧设备可以和第二网络侧设备协商系统信息变更通知的发送时间。
具体地,第一网络侧设备指示第二网络侧设备在第一预设时间发送系统信息变更通知。可选地,可以在指示消息中携带第一预设时间,或者指示第一预设时间和当前时间的差值等,在此不作限制。
即该实现方式中,第一网络侧设备在第一预设时间向第一终端发送所述系统信息变更通知。
类似地,第二网络侧设备也在第一预设时间向第二终端发送系统信息变更通知。
另一种实现方式中,第一网络侧设备向第二网络侧设备发送第一变更周期指示,该变更周期指示用于指示当前变更周期后与所述当前变更周期间隔n个周期的第一预设周期。其中,n为大于或等于0的整数。
n可以是预设值。第二网络侧设备根据第一变更周期指示可以知道在当前变更周期后的某个周期发送系统信息变更通知。例如n=0时,表明在当前变更周期的下一变更周期发系统信息变更通知。
需要说明的是,变更周期的长度可以都相同,也可以不同。如果变更周期不同的话,第一变更周期指示还可以用于指示第一预设周期的时间长度,在此不做限定。
相应地,第一网络侧设备在第一预设周期向第一终端发送所述系统信息变更通知。
类似地,第二网络侧设备也在第一预设周期向第二终端发送系统信息变更通知。
本实施例中,第一网络侧设备和第二网络侧设备同时向各自覆盖范围内的终端发送系统信息变更通知。
进一步地,一种可选的实施方式中,第一网络侧设备确定系统信息变更后,第一网络侧设备还可以向第二网络侧设备发送系统信息指示。该系统信息指示用于指示变更后的系统信息基于当前系统信息的变化。例如系统信息的参数加1、减1等,在此不做限制。
这种方式中,可以不用发送所有变更后的系统信息,而是指示变更后的系统信息基于当前系统信息的变化。这样第二网络侧设备收到系统信息指示后,就可以根据系统信息指示以及当前系统信息,确定出变更后的系统信息。
或者,另一种可选地实施方式中,第一网络侧设备还可以向第二网络侧设备发送变更后的系统信息。即直接发送变更后的系统信息。
在上述实施例的基础上,第一网络侧设备还将变更后的系统信息发送给第一终端。
这里第一终端可以是主动请求变更后的系统信息,也可以是接收第一网络侧设备发送的变更后的系统信息,在此不做限制。
相应地,第二网络侧设备将变更后的系统信息发送给第二终端。其中,第二终端也可以是主动请求变更后的系统信息,或者直接接收第二网络侧发送的变更后的系统信息。
可选地,第一网络侧设备可以将发送变更后的系统信息的时间告知第二网络侧设备,以便第一网络侧设备和第二网络侧设备同时向终端发送变更后的系统信息。
一种实施方式中,第一网络侧设备指示所述第二网络侧设备在第二预设时间发送变更后的系统信息。
相应地,第一网络侧设备在第二预设时间,将变更后的系统信息发送给所述第一终端。
第二网络侧设备在第二预设时间,将变更后的系统信息发送给所述第二终端。
或者,另一种实施方式中,第一网络侧设备向第二网络侧设备发送第二变更周期指示,该变更周期指示用于指示当前变更周期后与所述当前变更周 期间隔n个周期的第二预设周期,n为大于或等于0的整数。
n可以是预设值。第二网络侧设备根据第二变更周期指示可以知道在当前变更周期后的某个周期发送系统信息。例如n=0时,表明在当前变更周期的下一变更周期发系统信息。
需要说明的是,变更周期的长度可以都相同,也可以不同。如果变更周期不同的话,第二变更周期指示还可以用于指示第二预设周期的时间长度,在此不做限定。
相应地,第一网络侧设备在第二预设周期将变更后的系统信息发送给第一终端。
第二网络侧设备在第二预设周期将变更后的系统信息发送给第二终端。
可选地,终端在收到变更通知后,可以主动请求变更后的系统信息。
具体地,第一网络侧设备将所述变更后的系统信息发送给所述第一终端之前,第一网络侧设备接收所述第一终端发送的系统信息请求。该系统信息,所述系统信息请求用于请求所述变更后的系统信息。
类似地,第二网络侧设备将所述变更后的系统信息发送给所述第二终端之前,第二网络侧设备接收所述第二终端发送的系统信息请求。该系统信息,所述系统信息请求用于请求所述变更后的系统信息。
进一步地,第一网络侧设备还可以与第二网络侧设备协商变更后的系统信息的生效时间。即第一网络侧设备将变更后的系统信息的生效时间发送给至少一个协作的第二网络侧设备。生效即指开始使用变更后的系统信息。
需要说明的是,第一网络侧设备确定系统信息发生变更后,进一步确定变更后的系统信息。为了跟第二网络侧设备的系统信息保持一致,第一网络侧设备可以确定一个生效时间,并将生效时间告知第二网络侧设备,以便于一起使用变更后的系统信息。
当然,第一网络侧设备也可以在确定系统信息发生变更后,立即使用变更后的系统信息。第二网络侧设备也可以在收到第一网络侧设备发送的变更指示后,立即使用变更后的系统信息。在此不作限制。
系统信息发生变化时,版本信息也可能随之变化。
一种方式中,第一网络侧设备还可以向第二网络侧设备发送版本信息指 示。该版本信息指示用于指示变更后的系统信息的版本信息基于当前版本信息的变化。例如ValueTag的值基于当前ValueTag加1等,在此不具体限定。
第二网络侧设备根据版本信息指示确定变更后的系统信息的版本信息。
另一种方式中,第一网络侧设备向第二网络侧设备发送变更后的系统信息的版本信息。即直接告诉第二网络侧设备变更后的系统信息的版本信息。
另外,第一网络侧设备还将变更后的系统信息的版本信息发送给第一终端。
类似地,第二网络侧设备也将变更后的系统信息的版本信息发送给第二终端。
图3为本公开另一实施例提供的系统信息变更指示方法流程示意图。
在上述实施例的基础上,终端收到网络侧设备发送的需求系统信息变更通知后进行的操作也会有相应地改进。具体地,以第一网络侧设备覆盖范围内的终端举例说明,第二网络侧设备覆盖范围内的终端操作类似,可以参照,不再赘述。
如图3所示,该方法包括:
S301、终端接收第一网络侧设备发送的系统信息变更通知。
该终端可以是前述第一终端。当前该终端接入第一网络侧设备。
第一网络侧设备在系统信息变化时,会向终端发送系统信息变更通知。该系统信息变更通知用于指示系统信息发生了变化。
该系统信息发生了变化可以是系统信息的部分或全部参数发生了变化。
可选地,系统信息变更通知可以指示系统信息的一个或多个系统信息块(System Information Block,简称SIB)发生变化,或者指示一个SI发生变化,也可以指示一组SI发生变化,在此不作限制。
S302、终端接收第一网络侧设备发送的与该系统信息变更通知对应的系统信息。
其中,与该系统信息变更通知对应的系统信息就是上述变更后的系统信息。
可选地,第一网络侧设备发送系统信息变更通知后可以广播或向该终端单播该变更后的系统信息,也可以在终端需要时再发送该变更后的系统信息。
相应地,终端确定接收变更后的系统信息后,就可以主动接收第一网络侧设备发送的变更后的系统信息。例如主动请求,或者主动接收第一网络侧设备广播的变更后的系统信息,在此不作限制。
本实施例中,终端接收第一网络侧设备发送的系统信息变更通知;进而接收所述第一网络侧设备发送的与所述系统信息变更通知对应的系统信息。实现了终端在收到系统信息变更通知后,接收第一网络侧设备发送的与上述系统信息变更通知对应的系统信息,能够提高系统资源的利用率。另外,网络侧设备在发送系统信息变更通知之后,再发送与上述系统信息变更通知对应的系统信息,有助于提高系统资源的利用率。
在一种可能的实现方式中,终端确定接收与上述系统信息变更通知对应的系统信息之前,可以接收第一网络侧设备发送的系统信息的版本信息(例如ValueTag),终端根据该系统信息的版本信息确定接收该系统信息。
需要说明的是,系统信息的版本信息可以是与上述系统信息变更通知对应的系统信息的版本信息,即变更后的系统信息的版本信息。
如果该终端之前已经存储有版本信息,终端会比较已存储的版本信息和与上述系统信息变更通知对应的系统信息的版本信息是否相同,如果相同就不再接收与上述系统信息变更通知对应的系统信息。如果不同就确定接收与上述系统信息变更通知对应的系统信息。
具体地,终端根据系统信息的版本信息确定接收系统信息可以是:终端判断自身存储的版本信息是否与上述系统信息的版本信息相同;当自身存储的版本信息与上述系统信息的版本信息不同时,终端确定接收该系统信息。
其中,版本信息可以是ValueTag,系统信息中的部分系统信息块(SIB)与ValueTag关联,在ValueTag不变时,表明与ValueTag关联的SIB均不变。ValueTag发生变化表示与ValueTag关联的SIB均变化了,需要获取更新后的系统信息。以相关技术的标准中的ValueTag为例,ValueTag值携带在SIB1中,如果SIB1中的ValueTag与终端存储的ValueTag不同,表明除了SIB10、SIB11、SIB12之外的所有存储的系统信息都无效。
可选地,该版本信息可以直接携带在上述变更通知中。终端收到变更通知后,根据系统信息的版本信息与自身存储的版本信息进行比较。当然也可 以由其他消息来携带版本信息,本实施例不作限定。
对于新接入的终端,由于本身没有存储系统信息,可以确定接收系统信息。
在上述实施例的基础上,终端可以接收第二网络侧设备发送的指示消息,该指示消息用于指示系统信息变化。终端可以根据该指示消息确定是否接收第二网络侧设备发送的系统信息。
上述方案适用于终端从第一网络侧设备切换到第二网络侧设备的情况,如果第二网络侧设备的系统信息发生变化,而在终端接入第二网络侧设备前,第二网络侧设备已经发送过系统信息变更通知,第二网络侧设备可以向该终端发送指示消息,告知终端系统信息发生变化,终端根据该指示消息,确定是否接收第二网络侧设备发送的系统信息。
可选地,指示消息可以指示发生变化的系统信息,如果终端已经从第一网络侧设备接收过上述指示消息所指示的系统信息,可以不再接收第二网络侧设备发送的系统信息。
此外,指示消息中也可以携带系统信息的版本信息,便于终端根据已存储的版本信息和指示消息中的版本信息确定是否接收系统信息。
可选地,指示消息可以是下行控制信息(Downlink Control Information,简称DCI)。其中,DCI可以是下行控制信道(Physical Downlink Control Channel,简称PDCCH)对应的DCI,该DCI中包含指示系统信息变化的指示位。例如,利用相关技术中的DCI中的某个指示位指示系统信息是否发生变化,也可以增加1个bit位专门标识系统信息是否发生变化。或者,采用多个bit位具体标识发生变化的SIB,在此不具体限定。
相应地,终端可以在上述DCI指示系统信息发生变化时,确定接收系统信息;在上述DCI指示系统信息不变时,确定不接收系统信息;也可以根据DCI指示的发生变化的SI或SIB,确定是否接收系统信息。
进一步地,第一网络侧设备发送系统信息变更通知后,可以广播与上述系统信息变更通知对应的系统信息。例如,在当前变更周期的下一周期广播与上述系统信息变更通知对应的系统信息、或者在当前变更周期后的预设个变更周期后广播与上述系统信息变更通知对应的系统信息。对于这种情况, 终端在接收第一网络侧设备发送的与上述系统信息变更通知对应的系统信息之前,终端还接收第一网络侧设备发送的调度指示消息。该调度指示消息用于指示该第一网络侧设备在广播与上述系统信息变更通知对应的系统信息。更具体地,调度指示消息还用于指示第一网络侧设备正在广播的系统信息,即广播哪些系统信息。
可选地,终端可以根据调度指示消息确定是否接收上述系统信息。如果终端判断该调度指示消息指示第一网络侧设备正在广播的系统信息是否包含系统信息变更通知对应的系统信息。如果包含,则确定接收第一网络侧设备广播的系统信息,否则,确定不接收第一网络侧设备广播的系统信息。
相应地,终端接收第一网络侧设备发送的与上述系统信息变更通知对应的系统信息,可以是终端在预设周期内接收第一网络侧设备广播的与上述系统信息变更通知对应的系统信息。
可选地,该预设周期可以是当前周期后的某个变更周期,例如是当前变更周期后与该当前变更周期间隔n个周期的变更周期。其中,n为大于或等于0的整数。当n=0时,预设周期为当前变更周期的下一变更周期。该间隔n可以预设在终端内,也可以是第一网络侧设备通过专门的消息通知终端,在此不作限制。
上述预设周期可以是一个具体的变更周期,一个变更周期可以分为1个或多个连续的时间窗(window),第一网络侧设备在一个变更周期内广播与上述系统信息变更通知对应的系统信息,终端依次在各时间窗接收该系统信息。但是相关技术中,终端不知道谁是最后一个时间窗,即终端在最后一个时间窗接收完与上述系统信息变更通知对应的系统信息后,可能会继续等待系统信息,从而影响终端的后续操作,以及浪费终端的功耗。
本实施例中,可以在与上述系统信息变更通知对应的系统信息中携带广播指示信息,来指示下一时间窗是否还有系统信息。
可选地,终端在所述预设周期内接收所述第一网络侧设备广播的与上述系统信息变更通知对应的系统信息,可以是:终端在预设周期内的起始时间窗内开始接收第一网络侧设备广播的与上述系统信息变更通知对应的系统信息。终端根据广播指示信息,确定是否在当前时间窗后的下一时间窗继续接 收系统信息。
其中,可以在预设周期的最后一个时间窗发送的系统信息中携带广播指示信息,该广播指示信息指示当前时间窗是预设周期的最后一个时间窗或下一个时间窗无所述系统信息发送。也可以在每个时间窗发送的系统信息中携带广播指示信息,具体指示下一时间窗是否还有系统信息发送。
本实施例中,终端在最后一个时间窗接收完系统信息后,就可以不再等待系统信息,并可以为后续其他操作做准备,即可以快速进入后续操作,提高终端的执行效率。
另外,终端在自身需要时会向第一网络侧设备发送关于系统信息的第二系统信息请求,以请求第一网络侧设备发送系统信息。若终端具有正在向第一网络侧设备发送的关于系统信息的第二系统信息请求或具有等待向第一网络侧设备发送的第二系统信息请求,则该终端接收第一网络侧设备发送的系统信息变更通知之后,停止发送第二系统信息请求。或者,终端在预设时长中禁止发送第二系统信息请求。即,终端本来要向第一网络侧设备请求系统信息,但是系统信息变更通知告知终端系统信息发生了变化,那么终端暂不发送第二系统信息请求。
可选地,终端还可以根据具体情况在预设时长内不发送该第二系统信息请求。预设时长可以由终端确定,也可以提前预置或由网络侧设备指示,在此不再限制。
需要说明的是,上述具有等待向第一网络侧设备发送的第二系统信息请求的情况,可以是终端连续发送请求消息的情况下,终端需要收到第一网络侧设备反馈的响应后再发送下一请求消息。本实施例中,终端准备发送第二系统信息请求了,但还在等待第一网络侧设备的响应。
在上述实施例的基础上,终端接收第一网络侧设备发送的与上述系统信息变更通知对应的系统信息之前,终端向第一网络侧设备发送第一系统信息请求。该第一系统信息请求用于请求与上述系统信息变更通知对应的系统信息。即,终端收到变更通知后,可以主动请求与上述系统信息变更通知对应的系统信息。
具体实现时,终端可以在收到变更通知后,决定是否要发送第一系统信 息请求。可选地,终端可以根据自身需求和/或系统信息的版本信息,确定发送第一系统信息请求。
例如,终端接收第一网络侧设备发送的与上述系统信息变更通知对应的系统信息的版本信息,确定发送第一系统信息请求。例如跟自己存储的版本信息进行比较,如果版本信息相同,则不需要接收该系统信息,也就无需发送第一系统信息请求。当终端存储的版本信息与该系统信息的版本信息不同时,确定发送第一系统信息请求。
也有可能是,终端接收第一网络侧设备发送的调度指示消息,该调度指示消息用于指示第一网络侧设备正在广播的系统信息,即,指示正在广播哪些系统信息。如果终端判断调度指示消息指示的第一网络侧设备正在广播的系统信息不包含第一系统信息请求对应的系统信息,那么终端确定发送第一系统信息请求。如果调度指示消息指示第一网络侧设备正在广播的系统信息包含第一系统信息请求对应的系统信息,那么终端无需发送第一系统信息请求,直接在预设周期接收该系统信息即可。
终端也可以根据自身需求确定发送第一系统信息请求,可以是终端根据后续执行的功能确定发送第一系统信息请求,例如,终端后续要执行小区重选功能,那么需要发送第一系统信息请求,以获取小区重选功能对应的系统信息。当然不以此为限,也可以是根据其他需求发送第一系统信息请求。
进一步地,如果终端确定发送第一系统信息请求,终端还可以确定第一系统信息请求的发送时间,进而终端在该发送时间向第一网络侧设备发送第一系统信息请求。
其中,终端可以在收到变更通知后就发送第一系统信息请求。这种方式适用于已存储有系统信息的终端,但不以此为限,新接入的终端也可以收到变更通知后立即发送第一系统信息请求。
终端也可以在收到变更通知后先不发送第一系统信息请求。具体地,终端可以根据自身需求确定第一系统信息请求的发送时间,例如,根据后续要执行的功能需要的系统信息来确定第一系统信息请求的发送时间。举例说明,可以根据即将执行的广播功能确定第一系统信息请求的发送时间,以获取广播功能对应的系统信息。
需要说明的是,本公开实施例中的调度指示消息可以包含在第一网络侧设备发送的最小系统信息(minimum SI)中,但不以此为限。
一种可选地实施方式中,如果终端处于空闲态(idle)或去激活态(inactive),那么可以在随机接入过程中向第一网络侧设备发送第一系统信息请求。
需要说明的是,终端发起随机接入过程时,先向第一网络侧设备发送随机接入请求(MSG1),收到第一网络侧设备返回的随机接入响应后,再向第一网络侧设备发送随机接入配置请求(MSG3)。那么上述第一系统信息请求可以为MSG1或者MSG3。即利用随机接入请求或者随机接入配置请求来请求与上述系统信息变更通知对应的系统信息,可以在随机接入请求或者随机接入配置请求中携带用于请求与上述系统信息变更通知对应的系统信息的请求信息,在此不做限制。
另外,终端如果在连接态,需要传输数据,对于接收能力不足的终端,可以从连接态切换到空闲态或去激活态之后,再接收与上述系统信息变更通知对应的系统信息。即在接收第一网络侧设备发送的所述与上述系统信息变更通知对应的系统信息之前,终端从连接态切换到空闲态或去激活态。
可选地,第一网络侧设备收到终端发送的第一系统信息请求后,可以采用单播或广播的方式向终端发送与上述系统信息变更通知对应的系统信息。
如果第一网络侧设备采用单播的方式向终端发送与上述系统信息变更通知对应的系统信息,可以先调度该终端,进而单独向该终端发送与上述系统信息变更通知对应的系统信息。其中,第一网络侧设备可以向终端发送调度信息,该调度信息用于指示第一网络侧设备发送与上述系统信息变更通知对应的系统信息的资源位置。终端根据调度信息指示的资源位置,接收第一网络侧设备发送与系统信息变更通知对应的系统信息。
例如,调度信息指示第一网络侧设备发送与上述系统信息变更通知对应的系统信息所占用的时频资源等。相应地,终端可以在调度信息所指示的时频资源接收系统信息。
进一步地,本公开实施例中,也对系统信息相关的变更通知、版本信息等提出了新的内容。
其中,变更通知可以携带在下述任一消息中:最小系统信息(minimum SI)、寻呼消息、用于调度寻呼消息的PDCCH对应的DCI格式(format)、小区无线网络临时标识(Cell Radio Network Temporary Identifier,简称C-RNTI)加扰后的PDCCH对应的DCI格式(format)。
其中,minimum SI不需要终端的请求,可以是第一网络侧设备主动发送给终端的。不同PDCCH的DCI不同,即上述用于调度寻呼消息的PDCCH对应的DCI与C-RNTI加扰后的PDCCH对应的DCI不同。
变更通知中可以由1bit或多bit标识系统信息是否变化,以1bit为例,例如“1”标识发生变化,“0”标识没有变化。
具体地,变更通知中还可以包括:系统信息的变更标识集合,该变更标识集合用于标识对应系统信息是否发生变化。
系统信息的变更标识集合的粒度可以不同。例如包括:每个SIB(per-SIB)的变更标识。即变更通知中系统信息的每个SIB都有一个对应的标识位,来标识对应的SIB是否变化。或者,
包括:每个系统信息(Per-SI)的变更标识。即每个系统信息对应一个标识位,来标识是否变化。或者,
包括:每个系统信息组(per-SIB group)的变更标识。每个系统信息组包含一个或多个预设系统信息。或者,
包括:每个系统信息功能组(per-functionality)的变更标识。每个系统信息功能组包括一个或多个对应统一功能的系统信息。即可以将系统信息按功能划分到不同的功能组,例如小区重选对应的系统信息划分到同一个功能组。
进一步地,变更通知还可以包括下述一项或多项:系统信息标识、系统信息区域标识、版本信息。
其中,系统信息标识与上述变更标识集合对应。具体地,变更标识集合包括:每个系统信息块SIB的变更标识时,系统信息标识包括:每个系统信息块SIB的标识。当然,也可以以固定的bit位标识SIB,例如变更通知的第1比特位为SIB1的变更标识位,这样就不需要专门的系统信息标识了。
或者,变更标识集合包括:每个系统信息的变更标识时,系统信息标识包括:每个系统信息的标识。与SIB类似地,也可以以固定的bit位标识SI。
或者,变更标识集合包括:每个系统信息组的变更标识时,系统信息标识包括:每个系统信息组的标识。与SIB类似地,也可以以固定的bit位标识系统信息组。
或者,变更标识集合包括:每个系统信息功能组的变更标识时,系统信息标识包括:每个系统信息功能组的标识。与SIB类似地,也可以以固定的bit位标识系统信息功能组。
系统信息区域标识为下述任一种:小区标识(Cell ID)、小区组标识(Cell group ID)、收发节点标识(TRP ID)、收发节点组标识(TRP group ID)。
进一步地,上述版本信息可以包括下述一项或多项:系统信息值标签、系统信息标识、系统信息区域标识。
可以有Nbit系统信息值标签(ValueTag),N为大于0的整数。
系统信息标识包括下述任一种:每个系统信息块SIB的标识、每个系统信息的标识、每个系统信息组的标识、每个系统信息功能组的标识。与前述实施例类似,在此不再赘述。
系统信息区域标识为下述任一种:小区标识、小区组标识、收发节点标识、收发节点组标识。与前述实施例类似,在此不再赘述。
