具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
参见图1,图1为本公开实施例提供的网络结构示意图,如图1所示,包括一个或者多个用户设备11和网络侧设备12,其中,附图中以一个用户设备(UE,User Equipment)11进行举例示意。其中,用户设备11也可以称为终端,可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定用户设备11的具体类型。用户设备11可以与网络侧设备12建立通信,其中,附图中的网络可以表示用户设备11与网络侧设备12无线建立通信,网络侧设备12可以是基站,基站可以是宏站,如LTE eNB、5G NR NB(gNB)等;也可以是小站,如低功率节点(LPN:low power node)pico、femto等小站,或者可以是接入点(AP,access point);网络侧设备12也可以是中央单元(CU,central unit)与其管理和控制的多个传输接收点(TRP,Transmission Reception Point)共同组成的网络节点。另外,一个基站下有一个或多个小区(例如:不同的频点或扇区分裂)。需要说明的是,在本公开实施例中并不限定网络侧设备12的具体类型。
参见图2,本公开实施例提供一种系统信息获取方法,如图2所示,包括以下步骤:
201、用户设备接收网络侧设备发送的按需的系统信息的第一调度信息;
202、所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息。
本公开实施例中,按需的系统信息(on-demand SI)可以是网络侧设备包括的系统信息中的部分系统信息,或者网络侧设备的按需的系统信息可以是网络侧设备中除周期广播的系统信息(periodic broadcast SI)之外的系统信息。而周期广播的系统信息(periodic broadcast SI)可以是网络侧设备的系统信息中需要周期广播的系统信息,例如:除按需的系统信息之外的系统信息,或者用户设备驻留到小区并接入驻留小区的系统信息,如MIB、SIB1和SIB2中的全部或部分内容;或者UE驻留到小区并接入驻留小区必要的系统信息等等。 另外,按需的系统信息(on-demand SI)也可以理解为通过按需的方式进行传输的系统信息。
上述第一调度信息(scheduling information)可以是用于用户设备检测或者接收第一调度信息对应的按需的系统信息的相关信息,即用户设备通过第一调度信息能够检测或者接收到第一调度信息对应的按需的系统信息。另外,本公开实施例中,可以针对每一个按需的系统信息有一个调度信息,即一个调度信息对应一个按需的系统信息;也可以针对一组按需的系统信息有一个调度信息,即一个调度信息对应一组按需的系统信息。
上述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息可以是,用户设备基于上述第一调度信息执行获取所述网络侧设备发送的按需的系统信息的过程,该过程中获取的按需的系统信息可以是与上述第一调度信息不对应的按需的系统信息,当然,也可以是与第一调度信息对应的按需的系统信息。或者上述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息可以是,用户设备使用第一调度信息获取所述网络侧设备发送的按需的系统信息,这里获取的按需的系统信息可以是与第一调度信息对应的按需的系统信息。
需要说明的是,本公开实施例中,并不限定系统信息是MIB,以及SIB1~SIB20,例如:系统信息还可以是SIBn,其中,n为大于20的整数,或者系统信息还可以是适应未来无线通信系统的发展扩展的系统信息。其中:
SIB1可以包括广播小区接入与小区选择的相关参数以及SI消息的调度信息,可以包含了一个或多个SIB2~13;
SIB2可以包括小区内所有UE共用的无线参数配置,其它无线参数基本配置;
SIB3可以包括小区重选信息,主要关于服务小区重选参数以及同频小区重选参数;
SIB4可以包括同频邻区列表以及每个邻区的重选参数、同频白/黑名单小区列表;
SIB5可以包括异频相邻频点列表以及每个频点的重选参数、异频相邻小区列表以及每个邻区的重选参数、异频黑名单小区列表。

SIB11可以包括ETWS辅通知(secondary notification);
SIB12可以包括商业移动警报服务(Commercial Mobile Alert Service,CMAS)通知(CMAS notification);
SIB13可以包括获取跟一个或多个多播广播单频网络(Multicast Broadcast Single Frequency Network,MBSFN区域相关的多媒体广播组播功能(Multimedia Broadcast Multicast Service,MBMS)控制信息的信息。
SIB14~SIB20各有其针对的特性,不再一一描述。
另外,需要说明的是,步骤202获取的按需的系统信息可以包括上述用户设备需要的全部或者分部按需的系统信息,或者步骤202获取的按需的系统信息不包括上述用户设备需要的系统信息。例如:上述用户设备需要的按需的系统信息是SIB3和SIB4,而网络侧设备发送的按需的系统信息可能是SIB3和SIB4,或者SIB3和SIB5,或者SIB6、SIB7、SIB8和SIB9等等。且当用户设备接收到的按需的系统信息不包括用户设备需要的系统信息或者只包括上述用户设备需要的部分系统信息,则用户设备可以执行下一次按需的系统信息获取流程。
通过上述步骤可以实现用户设备基于上述第一调度信息获取网络侧设备发送的按需的系统信息,由于不是每次都广播全部的系统信息,从而可以达到节省传输资源的目的。
可选的,上述第一调度信息包括如下一项或者多项参数配置:
系统信息映射表、系统信息周期(SI period)、系统信息时间窗(SI-window)、起始点(start point)和传输次数(transmission number)其中,所述系统信息映射表用于表示所述第一调度信息对应的按需的系统信息。
该实施方式中,通过上述系统信息映射表用户设备可以知道上述第一调度信息对应哪些按需的系统信息,或者可以理解为通过上述系统信息映射表可以知道上述第一调度信息是哪些按需的系统信息的调度信息。优先的,上述系统信息映射表可以包括第一调度信息对应的按需的系统信息列表(SIB mapping list),可以针对每一个按需的系统信息有一个调度信息,也可以针对一组按需的系统信息有一个调度信息。上述系统信息映射表可以是索引列表(index list),也可以是指示系统信息索引(SIB index)的位图(bitmap),其中bitmap指示SIB1~SIBn(n为正整数,例如n=20)是否包含,如果包含,那么用1表示;否则,用0表示。
用户设备通过上述系统信息映射表就可以确定是否需要接收网络侧设备发送的按需的系统信息。例如:如果包括用户设备需要的按需的系统信息,则可以接收,如果不包括用户设备需要的按需的系统信息,则可以不接收。从而可以实现减少一些不必要的接收,例如:避免接收用户设备不需要的按需的系统信息。另外,这里的接收第一调度信息对应的广播周期内接收,且这里广播周期可以是通过上述系统信息周期确定的,也可以是用户设备与网络侧设备预先协商好的,对此本公开实施例不作限定。
上述系统信息周期可以是按需的系统信息的广播周期,或者可以是按需的系统信息的传输周期(transmission period),即网络侧设备广播发送按需的系统信息的传输机会的时间间隔。优先的,上述系统信息周期可以通过无线帧数来表示,例如:{rf8,rf16,rf32,rf64,rf128,rf256,rf512}。另外,按需的系统信息的广播周期可以比周期广播的系统信息的广播周期(传输周期)要长,例如:前者可以是后者的整数倍。通过上述系统信息周期用户设备就可以接收到网络侧设备发送的按需的系统信息,当然,这里可以结合上述系统信息映射表确定是否接收,也可以是不结合上述系统信息映射表,直接接收,接收后再判断是否包括用户设备需要的按需的系统信息。这里的接收可以是在下一个周期到达时接收,也可以是结合上述系统信息时间窗,在该系统信息时间窗内进行接收。
上述信息时间窗可以是用户设备接收按需的系统信息的时间窗长度。优先的,上述系统信息时间窗可以通过毫秒数来表示,例如:{ms1,ms2,ms5,ms10,ms15,ms20,ms40}。此外,系统信息时间窗内,UE可以不需要在连续的子帧上接收,某个子帧上是否传输,通过无线网络临时标识(SI-RNTI,system information-radio network temporary identifier)(例如OD-SI-RNTI)加扰的物理下行控制信道(PDCCH,Physical Downlink Control Channel)来指示,UE可以通过SI-RNTI进行寻址。另外,UE还可以通过混合自动重传请求(HARQ,Hybrid Automatic Repeat reQuest)重传合并(没有ACK/NACK反馈)将多个子帧合并接收来提高系统信息接收性能。同样的,这里广播周期可以是通过上述系统信息周期确定的,也可以是用户设备与网络侧设备预先协商好的,对此本公开实施例不作限定。
上述起始点可以是网络侧设备发送按需的系统信息的传输机会的每个时间间隔的起始点,也可以是每个系统信息周期内系统信息时间窗的起始位置(例如,起始无线帧、起始子帧)。通过该起始点用户设备可以及时接收到网络侧设备发送的按需的系统信息。
上述传输次数可以是网络侧设备发送按需的系统信息的次数,或者可以是在传输机会发送按需的系统信息的次数。这里的传输次数可以是网络侧设备在连续的广播周期内发送的次数,或者可以是在一个系统信息的修改周期(modification period)内网络侧设备发送按需的系统信息的次数。优先的,上述传输次数可以通过整数来表示,例如:{1,2,4,8,…,infinite},其中,infinite表示一直发送,进一步的,在一个系统信息的修改周期(modification period)内,每个广播周期都发送。通过上述传输次数可以让用户设备知道网络侧设备会发送多少次按需的系统信息,从而网络侧设备不需要每次发送按需的系统信息之前都发送一传输指示,从而可以节约网络资源和系统信令的开销。
需要说明的是,本公开实施例中,上述第一调度信息可以包括上述任一项参数配置就可以实现,并不限定需要包括多个或者全部的参数配置。且针对一些不同的应用场景可以包括不同的参数配置,例如:广播发送的按需的系统信息(OD SI)的调度信息可以包括系统信息周期、系统信息时间窗、起始点和传输次数,而对于组播发送的OD SI的调度信息可以包括系统信息时间窗和起 始点。
可选的,上述用户设备接收网络侧设备的按需的系统信息的第一调度信息,包括:
所述用户设备接收所述网络侧设备周期广播的系统信息(periodic broadcast SI),所述周期广播的系统信息包括按需的系统信息的第一调度信息。
该实施方式中,可以实现通过周期广播的系统信息发送按需的系统信息的第一调度信息。另外,上述周期广播的系统信息可以是只包括按需的系统信息的第一调度信息的系统信息,当然,在一些场景中上述周期广播的系统信息还可以包括其他需要周期广播的系统信息,例如,MIB、SIB1和SIB2。
可选的,所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,包括:
若所述第一调度信息包括预先指定的参数配置,所述用户设备使用所述第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息;或者
若所述第一调度信息包括预先指定的参数配置,且所述第一调度信息对应的按需的系统信息包括所述用户设备需要的按需的系统信息,所述用户设备使用所述第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息。
其中,上述预先指定的参数配置可以是系统信息映射表、系统信息周期、系统信息时间窗、起始点和系统信息传输次数,即上述预先指定的参数配置包括这五个参数配置。当然,在一些场景中,上述预先指定的参数配置可以是系统信息映射表、系统信息周期、系统信息时间窗、起始点和系统信息传输次数中的部分参数,例如:系统信息映射表、系统信息周期、系统信息时间窗和起始点,或者系统信息映射表、系统信息周期和起始点等等,对此本公开实施例不作限定。另外,上述预先指定的参数配置也可以称作完整的参数配置。
该实施方式中,可以实现若第一调度信息包括预先指定的参数配置,则用户设备可以直接使用第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息,从而可以减少用户设备执行的操作。例如:第一调度信息中包含完整的参数配置,可用于网络触发的按需的系统信息的广播发送,例如,公共预警系统(Public Warning System,PWS,包括ETWS和CMAS)的系统 信息,小区重选的系统信息,更新后的按需的系统信息等的广播发送。那么UE就可以根据该调度信息获取按需的系统信息。
另外,该实施方式中,还可以实现若第一调度信息包括预先指定的参数配置,且第一调度信息对应的按需的系统信息包括所述用户设备需要的按需的系统信息,用户设备才使用第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息,这样可以避免用户设备接收用户设备不需要的按需的系统信息。例如:如果用户设备收到按需的系统信息的调度信息,该调度信息中包含完整的参数配置,那么该用户设备查看是否包含自己需要的系统信息,如果包含,那么用户设备根据该调度信息获取所需的系统信息;如果不包含,则可以向网络侧设备发送按需的系统信息请求消息,其中,关于按需的系统信息请求消息请见下面实施方式的描述。
可选的,所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,包括:
所述用户设备根据所述第一调度信息确定是否需要向所述网络侧设备发送按需的系统信息请求消息(on-demand SI request message),;
若确定需要向所述网络侧设备发送按需的系统信息请求消息,则所述用户设备向所述网络侧设备发送按需的系统信息请求消息(on-demand SI request message),,所述按需的系统信息请求消息用于请求所述用户设备需要的按需的系统信息;
所述用户设备接收所述网络侧设备发送的按需的系统信息响应消息(on-demand SI response message)。
该实施方式中,可以实现用户设备向网络侧设备发送上述系统信息请求消息,以请求用户设备需要的系统信息。例如:上述用户设备需要的按需的系统信息是SIB3和SIB4,则用户设备可以向网络侧设备发送SIB3和SIB4对应的系统信息请求消息。
当网络侧设备接收到上述系统信息请求消息后,就可以根据该系统信息请求消息发送系统信息响应消息。或者可以是网络侧设备根据用户设备发送的按需的系统信息请求消息以及自己可以提供的按需的系统信息,发送按需的系统信息响应消息。其中,上述系统信息响应消息可以包括用户需要的全部或者部 分按需的系统信息。当然,在一些场景中,上述系统信息响应消息可能不包括用户设备需要的按需的系统信息,如果用户设备收到的按需的系统信息响应消息中不包含自己所需的系统信息,那么用户设备获知网络侧无法提供自己所需的系统信息。另外,如果用户设备没有收到网络侧的反馈,认为请求按需的系统信息失败,那么用户设备可以进行下一次的按需的系统信息调度过程。另外,上述按需的系统信息响应消息还可以包括其他用户设备需要的全部或者部分的按需的系统信息,或者不包括其他用户设备需要的按需的系统信息。或者上述按需的系统信息响应消息可以包括系统信息表格索引,这样用户设备可以从已保存的系统信息表格中查找与所述系统信息表格索引对应的按需的系统信息;其中,与系统信息表格索引对应的按需的系统信息可以包括用户设备需要的全部或者分部按需的系统信息,或者不包括所述用户设备需要的系统信息;以及与系统信息表格索引对应的按需的系统信息还可以包括其他用户设备需要的全部或者部分的按需的系统信息,或者与系统信息表格索引对应的按需的系统信息可以不包括其他用户设备需要的按需的系统。
该实施方式中,可以实现根据用户设备发送的按需的系统信息请求消息进行按需的系统信息发送,从而可以避免广播用户设备不需要的按需的系统信息,以避免传输资源浪费。
另外,网络侧设备可以使用SI-RNTI加扰的PDCCH调度按需的系统信息响应消息,各用户设备可以通过SI-RNTI进行寻址。且对于广播方式发送按需的系统信息响应消息,网络侧可以重复发送按需的系统信息,用户设备通过HARQ重传合并(没有ACK/NACK反馈)来提高系统信息接收性能。
其中,上述根据所述第一调度信息确定是否需要向所述网络侧设备发送按需的系统信息请求消息可以是根据上述第一调度信息确定第一调度信息对应的按需的系统信息不包括用户设备需要的全部或者部分按需的系统信息,或者上述第一调度信息中包括的参数配置不完整,即用户设备需要的参数配置有些是第一调度信息中不包括的等等,对此本公开实施例不作限定。
可选的,该实施方式中,上述方法还包括:
若所述系统信息响应消息中不包括所述用户设备需要的全部或者部分按需的系统信息,所述用户设备重新发送按需的系统信息请求消息;或者
若所述用户设备在预定义或者预配置时间内没有接收到所述系统信息响应消息,所述用户设备重新发送按需的系统信息请求消息。
这样可以实现当系统信息响应消息中不包括所述用户设备需要的全部或者部分按需的系统信息,或者在预定义或者预配置时间内没有接收到所述系统信息响应消息,用户设备重新发送按需的系统信息请求消息。例如:用户设备需要的按需的系统信息是SIB3,但系统信息响应消息不包括SIB3,从而用户设备需要重新发起系统信息请求消息。
其中,上述预定义或者预配置时间可以理解为预定义或配置的监听时间,即若在该时间内未监听到对应的系统信息响应消息,则认为SI request发送失败,需要重新发送。
可选的,所述用户设备根据所述第一调度信息确定是否需要向所述网络侧设备发送按需的系统信息请求消息,包括:
所述用户设备判断所述第一调度信息对应的按需的系统信息是否包括所述用户设备需要的按需的系统信息,若否,则确定需要向所述网络侧设备发送按需的系统信息请求消息;或者
所述用户设备判断所述第一调度信息包括的参数配置中是否只包括第一部分参数配置,若是,则确定需要向所述网络侧设备发送按需的系统信息请求消息。
该实施方式中,可以实现第一调度信息对应的按需的系统信息不包括用户设备需要的按需的系统信息,或者第一调度信息包括的参数配置中只包括第一部分参数配置,则确定需要发送按需的系统信息请求消息。其中,上述第一部分参数配置可以是预先设置的,例如:设定系统信息映射表、系统信息周期、系统信息时间窗和起始点,或者系统信息映射表、系统信息周期和起始点中的部分为上述第一部分参数配置,即只要第一调度信息没有包括上述五个参数配置,则确定者第一调度信息包括的参数配置中只包括第一部分参数配置。或者上述第一部分参数配置可以定义为上面实施例中预先指定的参数配置中的部分参数配置。例如:如果用户设备收到按需的系统信息的调度信息,该调度信息中包含部分的参数配置(例如,系统信息映射表、系统信息周期、系统信息时间窗和起始点中的一个或多个),可用于用户设备请求的按需的系统信息的 广播/组播发送,那么该用户设备确定需要发送按需的系统信息请求消息。
可选的,上述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,进一步还包括:
所述用户设备接收所述网络侧设备发送的系统信息变更指示(system Info Modification);
所述用户设备根据所述系统信息变更指示接收所述网络侧设备发送的按需的系统信息的第二调度信息,其中,所述第二调度信息对应的按需的系统信息包括所述用户设备需要的按需的系统信息,且所述第二调度信息包括预先指定的参数配置;
所述用户设备接收所述网络侧设备发送的按需的系统信息响应消息,包括:
所述用户设备使用所述第二调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息响应消息。
其中,上述系统信息变更指示用于通知用户设备将发生的系统信息变化。从而用户设备根据系统信息变更指示确定将发生的系统信息变化后,就可以接收所述网络侧设备发送的按需的系统信息的第二调度信息。另外,该实施方式中,上述按需的系统信息响应消息是与上述第二调度信息对应的,即网络侧设备是根据第二调度信息发送上述按需的系统信息响应消息的,从而用户设备使用第二调度信息包括的参数配置接收到按需的系统信息响应消息。
例如:在系统信息的修改周期内系统信息不可变的场景,即周期广播的系统信息以及其中的按需的系统信息的调度信息不可变,网络侧设备可以在paging(寻呼)消息中发送系统信息变更指示(system Info Modification),通知UE将发生的系统信息变化。然后,在下一个系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(第二调度信息),以及该调度信息对应的按需的系统信息响应消息。例如,用户设备查看原调度信息中不包含自己需要的系统信息,用户设备发送的按需的系统信息列表为{SIB3,SIB4},网络侧在paging消息中发送系统信息变更指示,通知用户设备将发生的系统信息变化。然后,网络侧根据用户设备发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在下一个系统信息的修改周期内周期广播 的系统信息中发送新的按需的系统信息的调度信息(包含SIB3、SIB4完整的参数配置),以及该调度信息对应的按需的系统信息响应消息,其中包含SIB3、SIB4的系统信息。其中,本公开实施例中的系统信息的修改周期可以是网络侧设备预先定义的,或者网络侧设备与用户设备预先协商的等,对此本公开实施例不作限定。
需要说明的是,该实施方式中,并不限定终端在下一个系统信息的修改周期内接收第二调度信息,例如:也可以是在当前系统信息的修改周期内根据上述系统信息变更指示接收第二调度信息,即该实施方式中,也可以应用于在系统信息的修改周期内系统信息可变的场景。
需要说明的是,本公开实施例中,关于预先指定的参数配置的解释说明可以参见预先指定的参数配置第一次出现时的相关说明,在其他地方不作赘述。
可选的,该实施方式中,所述方法还包括:
若所述用户设备根据所述系统信息变更指示确定所述网络侧设备变更的按需的系统信息中不包括所述用户设备需要的全部或者部分按需的系统信息,所述用户设备重新发送按需的系统信息请求消息。
该实施方式中,可以实现网络侧设备变更的按需的系统信息中不包括所述用户设备需要的全部或者部分按需的系统信息,用户设备重新发送按需的系统信息请求消息。例如:用户设备需要的按需的系统信息是SIB3,但变更前网络侧设备提供的按需的系统信息不包括SIB3,且上述系统信息变更指示所指示的变更后网络侧设备提供的按需的系统信息也不包括SIB3,从而用户设备需要重新发起系统信息请求消息。
另外,还可以实现如果网络侧设备变更的按需的系统信息中不包括所述用户设备需要的全部或者部分按需的系统信息用户设备可以不接收上述第二调度信息,即上述第二调度信息可以是在确定网络侧设备变更的按需的系统信息中包括所述用户设备需要的按需的系统信息的情况下接收的。
可选的,所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,进一步还包括:
所述用户设备接收所述网络侧设备发送的按需的系统信息的第三调度信息,其中,所述第三调度信息对应的按需的系统信息包括所述用户设备需要的 按需的系统信息,且所述第三调度信息包括预先指定的参数配置;
所述用户设备接收所述网络侧设备发送的按需的系统信息响应消息,包括:
所述用户设备使用所述第三调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息响应消息。
该实施方式中,可以直接发送上述第三调度信息,相比上述一实施方式,可以减少系统信息变更指示的传输,以节约网络传输资源。例如:在系统信息的修改周期内系统信息可变的场景,那么周期广播的系统信息以及其中的按需的系统信息的调度信息可变。网络侧设备可以在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(第三调度信息),以及该调度信息对应的按需的系统信息响应消息。例如,用户设备查看原调度信息中不包含自己需要的系统信息,用户设备发送的按需的系统信息列表为{SIB3,SIB4},网络侧根据用户设备发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(包含SIB3、SIB4完整的参数配置),以及该调度信息对应的按需的系统信息响应消息,其中包含SIB3、SIB4的系统信息。这样用户设备就可以获取到自己需要的按需的系统信息。
另外,该实施方式中还可以应用系统信息的修改周期内系统信息不可变的场景,例如:终端可以默认在下一个系统信息的修改周期内接收所述第三调度信息。
可选的,所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,进一步还包括:
所述用户设备接收所述网络侧设备发送的按需的系统信息的第四调度信息,其中,所述第四调度信息对应的按需的系统信息包括所述用户设备需要的按需的系统信息,且所述第四调度信息包括第二部分参数配置;
所述用户设备接收所述网络侧设备发送的按需的系统信息响应消息,包括:
若所述第一调度信息包括的参数配置中包括第一部分参数配置,所述用户设备使用所述第一部分参数配置和所述第二部分参数配置接收所述网络侧设 备发送的按需的系统信息响应消息。
该实施方式中,上述第二部分参数配置可以是上面实施方式中介绍的第一部分参数配置之外的参数配置,例如:上述第一部分参数配置为预先指定的参数配置中的一部分,则第二部分参数配置为该预先指定的参数配置中的另一部分。当然,在一些场景中,上述第二部分参数配置与第一部分参数配置之和也可以是上述预先指定的参数配置中的一部分,对此本公开实施例不作限定。
例如:在系统信息的修改周期内系统信息可变的场景,那么周期广播的系统信息以及其中的按需的系统信息的调度信息可变。网络侧设备可以在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(第四调度信息),以及该调度信息对应的按需的系统信息响应消息。例如,用户设备收到按需的系统信息的第一调度信息(包含部分的参数配置,例如,系统信息映射表为{SIB5,SIB6}、系统信息周期为8rf、系统信息时间窗为5ms)。用户设备发送的按需的系统信息列表为{SIB5},网络侧设备根据该用户设备发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(包含SIB5、SIB6另一部分的参数配置,例如,起始点为SFNmod8=0的起始无线帧以及无线帧中第2号起始子帧,传输次数为2),即第四调度信息,以及该调度信息对应的按需的系统信息响应消息,其中包含SIB5、SIB6的系统信息。这样用户设备就可以使用所述第一部分参数配置和所述第二部分参数配置接收所述网络侧设备发送的按需的系统信息响应消息。由于该实施方式中,是使用所述第一部分参数配置和所述第二部分参数配置进行接收的,这样可以减少第四调度信息的开销,以节约网络资源。
同样的,该实施方式中还可以应用系统信息的修改周期内系统信息不可变的场景,例如:终端可以默认在下一个系统信息的修改周期内接收所述第四调度信息。
可选的,上述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,进一步还包括:
所述用户设备接收所述网络侧设备发送的传输指示,所述传输指示用于指示系统信息响应消息根据所述第一调度信息发送;
所述用户设备接收所述网络侧设备发送的按需的系统信息响应消息,包括:
所述用户设备使用所述第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息响应消息。
该实施方式中,可以实现通过上述传输指示通知用户设备系统信息响应消息根据所述第一调度信息发送,从而用户使用所述第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息响应消息。这样可以避免其他调度信息的传输,以节约网络资源。其中,上述第一调度信息包括的参数配置可以是预先指定的参数配置,也可以是部分参数配置,例如:上面实施方式中,介绍的第一部分参数配置。
例如:在系统信息的修改周期内系统信息可变的场景,那么周期广播的系统信息以及其中的按需的系统信息的调度信息可变。网络侧设备在当前系统信息的修改周期内周期广播的系统信息中发送传输指示(1bit指示或列表),以及第一调度信息对应的按需的系统信息响应消息。例如,用户设备收到按需的系统信息的第一调度信息(包含部分的参数配置,例如,系统信息映射表为{SIB7}、系统信息周期为16rf、系统信息时间窗为5ms,起始点为SFNmod16=1的起始无线帧以及无线帧中第3号起始子帧)。用户设备发送的按需的系统信息列表为{SIB7},网络侧设备根据该用户设备发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在当前系统信息的修改周期内周期广播的系统信息中发送传输指示(例如,1bit指示SIB7根据原调度信息进行发送),以及原调度信息对应的按需的系统信息响应消息,其中包含SIB7的系统信息。
同样的,该实施方式中还可以应用系统信息的修改周期内系统信息不可变的场景,例如:终端可以默认在下一个系统信息的修改周期内接收传输指示。
可选的,上述方法还包括:
所述用户设备接收所述网络侧设备发送的指示信息,所述指示信息为所述网络侧设备提供按需的系统信息的指示信息;
所述用户设备根据所述指示信息向所述网络侧设备发送按需的系统信息请求消息,所述按需的系统信息请求消息用于请求所述用户设备需要的按需的 系统信息;
所述用户设备接收网络侧设备发送的按需的系统信息的第一调度信息,包括:
所述用户设备接收网络侧设备发送的所述用户设备需要的按需的系统信息的第一调度信息;
所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息,包括:
所述用户设备使用所述第一调度信息包括的参数配置接收所述网络侧设备发送的按需的系统信息响应消息。
该实施方式中,可以实现根据上述指示信息发起按需的系统信息请求消息。例如:上述指示信息指示网络侧设备会提供按需的系统信息,则用户设备就可以发起按需的系统信息请求消息。且网络侧设备发送的第一调度信息为用户设备需要的按需的系统信息的第一调度信息,这样可以实现用户设备使用第一调度信息接收到上述按需的系统信息的响应消息。当然,上述系统信息响应消息可以包括用户需要的全部或者部分按需的系统信息。当然,在一些场景中,上述系统信息响应消息可能不包括用户设备需要的按需的系统信息,如果用户设备收到的按需的系统信息响应消息中不包含自己所需的系统信息,那么用户设备获知网络侧无法提供自己所需的系统信息。另外,如果用户设备没有收到网络侧的反馈,认为请求按需的系统信息失败,那么用户设备可以进行下一次的按需的系统信息调度过程。另外,上述指示信息可以是通过周期广播的系统信息(periodic broadcast SI),即网络侧设备通过周期广播的系统信息发送上述指示信息。
可选的,所述指示信息用于指示所述网络侧设备是否提供按需的系统信息;或者所述指示信息包括所述网络侧设备提供的按需的系统信息的系统信息列表;
所述用户设备根据所述指示信息向所述网络侧设备发送按需的系统信息请求消息,包括:
若所述指示信息指示所述网络侧设备提供按需的系统信息,则所述用户设备向所述网络侧设备发送按需的系统信息请求消息;或者
若系统信息列表指示的按需的系统信息包括所述用户设备需要的按需的系统信息,则所述用户设备向所述网络侧设备发送按需的系统信息请求消息。
该实施方式中,上述指示信息可以分为两种情况,一种是指示网络侧设备是否提供按需的系统信息,例如用1比特指示,1表示有,0表示没有;或者提供时用真(true)表示,不提供则无该指示。另一种是指示网络侧设备提供哪些按需的系统信息。可以是索引列表index list,也可以是指示SIB index的bitmap,其中bitmap指示SIB1~SIBn(n为正整数,例如n=20)是否提供,如果提供,那么用1表示;否则,用0表示。其中,该实施方式中的提供可以是指在下一个广播周期或者当前修改周期或者下一个修改周期是否提供。
这样,如果用户设备收到按需的系统信息的存在指示为1或者true,指示网络侧可以提供按需的系统信息,那么该用户设备就发送按需的系统信息请求消息。如果用户设备收到按需的系统信息列表,指示网络侧提供哪些按需的系统信息,那么该用户设备查看是否包含自己需要的系统信息,如果包含,那么该用户设备就发送按需的系统信息请求消息。
例如:针对上述指示为1或者true的指示信息,网络侧设备在接收到用户设备发送的上述按需的系统信息请求消息后,就可以在当前系统信息的修改周期内周期广播的系统信息中发送按需的系统信息的第一调度信息(可以包含完整的参数配置),以及该调度信息对应的按需的系统信息响应消息。例如,用户设备收到按需的系统信息的存在指示为1或者true,指示网络侧可以提供按需的系统信息,用户设备发送的按需的系统信息列表为{SIB13},网络侧设备根据该用户设备发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(包含SIB13完整的参数配置),以及该调度信息对应的按需的系统信息响应消息,其中包含SIB13的系统信息。
又例如:针对指示网络侧设备提供按需的系统信息包含用户设备需要的系统信息,网络侧设备在接收到用户设备发送的上述按需的系统信息请求消息后,就可以在当前系统信息的修改周期内周期广播的系统信息中发送按需的系统信息的第一调度信息(可以包含完整的参数配置),以及该调度信息对应的按需的系统信息响应消息。例如,用户设备1和用户设备2收到按需的系统信 息列表{00111111110000000000},指示网络侧提供SIB3~SIB10,UE5查看包含自己需要的系统信息SIB8,用户设备1发送的按需的系统信息列表为{SIB8},UE6查看包含自己需要的系统信息SIB9,用户设备2发送的按需的系统信息列表为{SIB9},网络侧根据用户设备1和用户设备2发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在当前系统信息的修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(包含SIB8、SIB9完整的参数配置),以及该调度信息对应的按需的系统信息响应消息,其中包含SIB8、SIB9的系统信息。
可选的,上述用户设备向所述网络侧设备发送按需的系统信息请求消息,包括:
所述用户设备通过随机接入过程的Msg3向所述网络侧设备发送按需的系统信息请求消息;或者
所述用户设备通过RRC消息向所述网络侧设备发送按需的系统信息请求消息;或者
所述用户设备通过MAC CE向所述网络侧设备发送按需的系统信息请求消息。
该实施方式中,可以实现通过随机接入过程的Msg3、RRC消息或者MAC CE向所述网络侧设备发送按需的系统信息请求消息。例如:空闲态/非激活用户设备通过随机接入过程进行按需的系统信息请求消息发送。也就是在随机接入过程的Msg3中包含按需的系统信息请求消息,其中包含按需的系统信息列表。例如,当UE所需的系统信息是SIB3和SIB4,那么UE发送的按需的系统信息请求消息中包含的按需的系统信息列表为{SIB3,SIB4}或{00110000000000000000}。又例如:连接态用户设备通过RRC消息或MAC CE进行按需的系统信息请求消息发送。也就是UE在RRC消息或MAC CE中包含按需的系统信息请求消息,其中包含按需的系统信息列表。
可选的,上述方法还包括:
所述用户设备获取上行信号与按需的系统信息的映射关系信息;
所述用户设备向所述网络侧设备发送按需的系统信息请求消息,包括:
所述用户设备向所述网络侧设备发送上行信号,其中,所述上行信号与所 述用户设备需要的按需的系统信息存在映射关系。
该实施方式中,上述映射关系信息可以是从接收到周期广播的系统信息中获取的,即网络侧设备发送的周期广播的系统信息中包括上述映射关系信息,或者用户设备预先配置的,从而从本地获取上述映射关系信息。该实施方式中,可以通过发送上述上行信号,以告知网络侧设备用户设备需要的按需的系统信息,而发送上行信号是基于现有流程实现的,从而可以减少通信流程,以及用户设备和网络侧设备的改进。当然,网络侧设备也是预先获取有上述映射关系信息。例如:空闲态/非激活用户设备通过上行信号过程进行按需的系统信息请求消息发送。也就是用户设备发送上行信号(例如,Preamble前导码,Sync同步码等),该上行信号与按需的系统信息存在映射表。例如,Preamble1对应SIB3,Preamle2对应SIB4或Preamble3对应SIB3和SIB4。
需要说明的是,本公开实施例中介绍的实施方式中可以相互结合实现,也可以单独实现,对此本公开实施例不作限定。
本公开实施例,用户设备接收网络侧设备发送的按需的系统信息的第一调度信息;所述用户设备基于所述第一调度信息获取所述网络侧设备发送的按需的系统信息。这样可以实现系统信息按需发送,相比相关技术所有系统信息都是周期广播,本公开实施例可以减少系统信息的开销。

301、网络侧设备向用户设备发送按需的系统信息的第一调度信息;
302、网络侧设备向所述用户设备发送按需的系统信息。

需要说明的是,本实施例作为与图2所示的实施例中对应的网络侧设备的实施方式,其具体的实施方式可以参见图2所示的实施例的相关说明,以为避免重复说明,本实施例不再赘述。本实施例中,同样可以实现减少系统信息的开销。
下面以多个举例对上面实施例中介绍的实施方式进行举例说明:
例1:
该举例以空闲态/非激活UE进行网络侧触发的按需的系统信息调度过程进行举例说明,该举例网络侧触发的按需的系统信息调度示意图可以参见图4,其中,具体工作流程如下:
步骤1:空闲态/非激活UE1,UE2,…,UEn(n为整数)接收网络侧设备周期广播发送的系统信息,其中包含按需的系统信息的调度信息,并包含完整的参数配置,可用于网络触发的按需的系统信息的广播发送,例如,PWS(包括ETWS和CMAS)的系统信息广播发送。
步骤2:网络侧设备根据调度信息广播发送按需的系统信息响应消息,其中包含PWS的系统信息。具体的,网络侧用SI-RNTI加扰的PDCCH调度按需的系统信息响应消息。
步骤3:UE1,UE2,…,UEn根据PWS调度信息接收按需的系统信息响应消息。具体的,UE1,UE2,…,UEn通过SI-RNTI进行寻址,从而获得PWS的系统信息。
例2:
该举例中系统信息的修改周期内系统信息不变,以空闲态/非激活UE收到按需的系统信息的调度信息进行按需的系统信息调度过程进行举例说明,该 举例按需的系统信息的调度信息下按需的系统信息调度示意图可以参见图5,具体工作流程如下:
步骤1:空闲态/非激活UE1接收网络侧周期广播发送的系统信息,其中包含按需的系统信息的调度信息,并包含完整的参数配置,例如,PWS(包括ETWS和CMAS)的系统信息广播发送。
步骤2:UE1查看是否包含自己需要的系统信息SIB3和SIB4,由于不包含,所以UE1向网络侧发送按需的系统信息请求消息,其中包含的按需的系统信息列表为{SIB3,SIB4}。
步骤3:由于修改周期内系统信息不可变,所以按需的系统信息的调度信息不可变,网络侧在paging(寻呼)消息中发送系统信息变更指示(systemInfoModification),通知UE1,UE2,…,UEn(n为整数)将发生的系统信息变化。
步骤4:网络侧设备根据UE1发送的按需的系统信息请求消息,结合自己可提供的按需的系统信息,在下一个修改周期内周期广播的系统信息中发送新的按需的系统信息的调度信息(包含SIB3、SIB4完整的参数配置),以及该调度信息对应的按需的系统信息响应消息,其中包含SIB3、SIB4的系统信息。
步骤4:UE1根据SIB3、SIB4调度信息接收按需的系统信息响应消息。具体的,UE1通过SI-RNTI进行寻址,从而获得SIB3、SIB4的系统信息。
例3:
该举例系统信息的修改周期内系统信息不变,以空闲态/非激活UE收到按需的系统信息列表情况下进行按需的系统信息调度过程进行举例说明。该举例中按需的系统信息列表情况下按需的系统信息调度示意图可以参见图6,具体工作流程如下:
