为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例提供的信息指示方法进行详细介绍之前,先对本申请实施例涉及的名词、应用场景和实施环境进行简单介绍。
首先,对本申请实施例涉及的名词进行简单介绍。
回程链路:(Backhaul link),又可称为无线回传链路,是指IAB基站之间的通信链路,用于数据的回传。
广播信息:为PBCH(Physical Broadcast Channel,物理广播信道)信道承载的信息,包括来自高层的MIB(Master information block,主信息块)信息和来自层1的8比特信息。其中,该层1一般理解为 物理层。
MIB信息:共A比特,A为正整数,包括设备(如UE设备)接入基站所需信息中的部分信息,比如cellbarred等,其中,该cellbarred用于指示小区的接入控制状态。具体地,MIB信息包括6比特SFN(System Frame Number,系统帧号),1比特子载波间隔信息,4比特SSB(Synchronization signal block,同步信号块)的子载波偏移,DMRS(Demodulation Reference Signal,解调参考信号)相关信息,调度SIB(System information block,系统信息块)的PDCCH(Physical Downlink Control CHannel,物理下行控制信道)的资源信息等,另外,MIB信息还包括了一个空闲比特位。在标准中,MIB信息的具体定义如下:
MIB::=SEQUENCE{
systemFrameNumberBIT STRING(SIZE(6)),
subCarrierSpacingCommon ENUMERATED{scs15or60,scs30or120},
ssb-SubcarrierOffset INTEGER(0..15),
dmrs-TypeA-Position ENUMERATED{pos2,pos3},
pdcch-ConfigSIB1 PDCCH-ConfigSIB1,
cellBarred ENUMERATED{barred,notBarred},
intraFreqReselection ENUMERATED{allowed,notAllowed},
spare BIT STRING(SIZE(1))
}
层1的8比特信息:是指PBCH承载的信息中除MIB之外的信息,为了便于描述,将该8比特信息所在的比特位记为
通常,
中的信息用于指示SFN的最低4位;
中的信息为半帧指示信息,即指示该比特是前半帧还是后半帧。当IAB基站的系统频带大于6GHz(即L
SSB=64)时,
为PBCH编号的最高3位,否则,当系统频带小于6GHz时,即L
SSB小于64时,层1相关的信息有2比特保留比特位,具体地,
为参数k
SSB的最高位,
为保留比特位。其中,L
SSB为最大的SSB个数,k
SSB为SSB的子载波偏移信息。为了便于描述,这里可以将该层1的8比特信息所在的比特位可称为附加比特位。
系统信息:为设备接入基站所需信息的另一部分信息,即与MIB信息组成设备接入基站所需的全部信息。其中,该系统信息可以为SIB1信息。
SIB1信息:包括cellReservedForOperatorUse和cellReservedForOtherUse两个参数。其中,该cellReservedForOperatorUse和cellReservedForOtherUse两个参数与MIB信息中的cellBarred可以共同用于确定小区的接入控制状态,或者说,可以用于UE确定是否可以接入IAB基站。目前,cellReservedForOperatorUse、cellReservedForOtherUse和cellBarred定义为:当cellBarred=“not barred”,并且cellReservedForOperatorUse=“not reserved”,以及cellReservedForOtherUse=not“true”时,小区状态为允许UE接入,即UE可以将小区作为小区选择或者重选的候选小区;当cellBarred=“barred”或者,cellReservedForOtherUse=“true”时,小区状态为不允许UE接入;当cellBarred=“not barred”,并且,cellReservedForOperatorUse=“reserved”,以及cellReservedForOtherUse=not“true”时,小区状态为允许部分接入类型的UE接入。
此外,对本申请实施例涉及的应用场景进行简单介绍。
IAB基站是指为用户提供无线接入的基站,通常需要回程链路连接至核心网或者其他IAB基站,以便于进行数据回传,也即是,IAB基站可以支持UE接入,也可以支持其他IAB基站接入。一般情况下,考虑到部署的复杂性和灵活性,IAB基站与其他IAB基站之间的回程链路大多数采用无线回传,比如采用微波回传。随着5G部署步伐的加快,网络容量、复杂性、时延要求逐渐提高,移动基站的数量也逐渐增加,因此,无线回传的应用范围逐渐扩大,从而使得IAB基站更容易部署在密集和复杂场景,减轻了部署有线传输网络的负担。
针对无线回传,当前尚无技术记载如何实现对其他IAB基站的接入控制。在一些场景中,往往可能需要对其他IAB基站的接入和对UE的接入分别进行控制,譬如可能需要只允许IAB基站接入,所以,为了能够提高IAB基站的接入控制的灵活性,本申请实施例提供了一种信息提示方法,该信息提示方法可以对IAB基站的接入单独进行控制,即将与对UE的接入分离开分别进行控制,从而可以提高IAB基站的接入控制的灵活性,其具体实现请参见如下实施例。
接下来,对本申请实施例涉及的实施环境进行简单介绍。
请参考图1,该图1是根据一示例性实施例示出的一种实施环境的示意图,该实施环境中包括多个IAB基站110和UE 120。每个IAB基站110可以通过无线接入链路与所服务的UE120进行数据通信,并且,该多个IAB基站110之间可以通过无线回传链路进行数据回传。
为了便于描述和理解,这里将该多个IAB基站110中向其他IAB基站提供无线回传功能的IAB基站称为第一IAB基站,并且,将与该第一IAB基站无线连接的其他IAB基站称为第二IAB基站。
在介绍完本申请实施例提供的名词、应用场景和实施环境后,接下来将结合附图对本申请实施例提供的信息指示方法进行详细介绍。
请参考图2,该图2是根据一示例性实施例示出的一种信息指示方法的流程图,该信息指示方法可以包括如下几个实现步骤:
步骤201:第一IAB基站发送指示信息,其中,该指示信息用于指示是否允许其他IAB基站接入。
具体地,第一IAB基站发送指示信息可以包括:第一IAB基站发送系统信息和广播信息中的至少一个,其中,该系统信息和广播信息中的至少一个包括该指示信息。
也就是说,该第一IAB基站可以通过系统信息和广播信息中的至少一个来携带该指示信息,换句话来说,该第一IAB基站可以只通过该系统信息携带该指示信息,或者,也可以只通过该广播信息携带该指示信息,再或者,还可以通过该系统信息和广播信息携带该指示信息。
其中,该系统信息可以为SIB1信息。另外,该广播信息可以为PBCH信道承载的信息。
进一步地,该第一IAB基站发送指示信息可以包括:该第一IAB基站广播指示信息。也就是说,该第一IAB基站可以采用广播的方式来发送该指示信息,以便于能够监听到该指示信息的其他IAB基站可以根据该指示信息确定是否可以接入该第一IAB基站。
步骤202:第二IAB基站接收该指示信息,该指示信息用于指示是否允许其他IAB基站接入第一IAB基站。
进一步地,该第二IAB基站接收该指示信息的具体实现可以包括:接收系统信息和广播信息中的至少一个,其中,该系统信息和广播信息中的至少一个包括该指示信息。
具体地,当该第一IAB基站通过系统信息携带该指示信息时,该第二IAB基站接收该系统信息。或者,当该第一IAB基站通过广播信息携带该指示信息时,该第二IAB基站接收该广播信息。再或者,当该第一IAB基站通过系统信息和广播信息携带该指示信息时,该第二IAB基站接收该系统信息和广播信息。
在一种可能的实现方式中,当第一IAB基站采用广播的方式发送该指示信息时,该第二IAB基站可以周期监听该指示信息,以接收该指示信息。也即是,可以每隔参考时长,监听第一IAB基站广播的指示信息。其中,该参考时长可以根据实际需求进行设置,本申请实施例对此不做限定。
步骤203:第二IAB基站基于该指示信息,确定是否接入该第一IAB基站。
具体地,当该指示信息指示允许其他IAB基站接入该第一IAB基站时,第二IAB基站确定可以接入该第一IAB基站,否则,当该指示信息指示不允许其他IAB基站接入该第一IAB基站时,该第二IAB基站确定不可以接入该第一IAB基站。
在本申请实施例中,第一IAB基站发送指示信息,由于该指示信息用于指示是否允许其他IAB基站接入该第一IAB基站,因此,第二IAB基站接收该指示信息后,可以确定是否接入该第一IAB基站。如此通过该指示信息单独控制其他IAB基站的接入,即将与对UE的接入分离开分别进行控制,提高了IAB基站的接入控制的灵活性。
根据图2所示实施例可知,该第一IAB基站发送系统信息和广播信息中的至少一个,以通过该系统信息和广播信息中的至少一个携带指示信息,也就意味着,该第一IAB基站可能只通过系统信息携带该指示信息,也可能只通过广播信息携带该指示信息,或者,还可能通过系统信息和广播信息携带该指示信息。根据实现方式不同,接下来将通过如下几个具体实例分别进行介绍。
请参考图3,该图3是根据一示例性实施例示出的一种信息指示方法的流程图,该信息指示方法可以包括如下几个步骤:
步骤301:第一IAB基站发送系统信息,该系统信息包括第一参数和第二参数,该第一参数用于指示是否保留为运营商使用的小区,该第二参数用于指示是否保留为其他用途使用的小区。
进一步地,该第一IAB基站广播指示信息,即可以采用广播的方式发送该指示信息。在一些实施例中,该系统信息可以为SIB1信息,此时,该第一参数可以为cellReservedForOperatorUse,该第二参数可以为cellReservedForOtherUse。
步骤302:第一IAB基站发送广播信息,该广播信息包括主信息块MIB信息,该MIB信息包括第一小区禁止信息。
进一步地,该第一IAB基站广播该广播信息,也即是,该第一IAB基站可以采用广播的方法发送广播信息。
需要说明的是,该步骤与步骤301之间没有明确的先后执行顺序,即第一IAB基站可以在不同时刻分别发送该系统信息和该广播信息,或者,也可以同时发送该系统信息和广播信息,本申请实施例对此不作限定。
在一种可能的实现方式中,该第一小区禁止信息可以为cellbarred,用于指示小区的接入控制状态。
其中,该第一参数和该第二参数中的至少一个以及该第一小区禁止信息组成该指示信息。进一步地,当该第一参数和第二参数中的至少一个的内容以及该第一小区禁止信息的内容满足第一参考条件时,该指示信息用于指示允许其他IAB基站接入;当该第一参数和第二参数中的至少一个的内容以及该第一小区禁止信息的内容不满足第一参考条件时,该指示信息用于指示不允许其他IAB基站接入。
进一步地,可以采用cellReservedForOperatorUse和cellReservedForOtherUse中的至少一个以及cellbarred来组成该指示信息,并且,在实施中可以根据cellReservedForOperatorUse和cellReservedForOtherUse中的至少一个的内容以及cellbarred的内容是否满足第一参数条件来指示是否允许其他IAB基站接入。其中,正如前文所述,由于目前cellbarred、cellReservedForOperatorUse和cellReservedForOtherUse这三个参数可以用于指示是否允许UE接入IAB基站,因此,为了不影响对UE的接入控制,在一种可能的实现方式中,该第一参考条件可以包括如下情况中的至少一种:
第一种:第一小区禁止信息指示禁止接入第一IAB基站,并且,第二参数指示保留为其他用途使用的小区。
第二种:第一小区禁止信息指示禁止接入第一IAB基站,并且,第一参数指示保留为运营商使用的小区。
第三种:第一小区禁止信息指示禁止接入第一IAB基站,并且,第一参数指示保留为运营商使用的小区,以及第二参数指示保留为其他用途使用的小区。
第四种:第一小区禁止信息指示禁止接入第一IAB基站,并且,第一参数指示保留为运营商使用的小区或者第二参数指示保留为其他用途使用的小区。
第五种:第一小区禁止信息指示非禁止接入第一IAB基站,并且,第一参数指示保留为运营商使用的小区,以及第二参数指示保留为其他用途使用的小区。
第六种:第一小区禁止信息指示非禁止接入第一IAB基站,并且,第二参数指示保留为其他用途使用的小区。
也就是说,当该第一参数和第二参数中至少一个的内容以及第一小区禁止信息的内容满足上述六种情况中的至少一种情况时,该指示信息用于指示允许其他IAB基站接入,否则,当该第一参数和第二参数中至少一个的内容以及第一小区禁止信息的内容不满足上述六种情况时,该指示信息用于指示不允许其他IAB基站接入。
譬如,当cellBarred="barred",并且cellReservedForOtherUse="true"时,该指示信息用于指示允许其他IAB基站接入。当cellBarred="barred",并且cellReservedForOperatorUse="reserved",该指示信息用于指示允许其他IAB基站接入。当cellBarred="barred",并且cellReservedForOperatorUse="reserved,该指示信息用于指示允许其他IAB基站接入。当cellBarred="barred",并且(cellReservedForOperatorUse="reserved,或者cellReservedForOtherUse="true")时,该指示信息用于指示允许其他IAB基站接入。当cellBarred="not barred",并且cellReservedForOperatorUse="reserved",并且cellReservedForOtherUse="true",该指示信息用于指示允许其他IAB基站接入。当cellBarred="not barred",并且cellReservedForOtherUse="true"),该指示信息用于指示允许其他IAB基站接入。否则,该指示信息用于指示不允许其他IAB基站接入。
值得一提的是,本实施例不需要额外增加新的信息,而是利用通信技术中已使用的与小区状态相关的参数cellBarred、cellReservedForOtherUse和cellReservedForOperatorUse来组成指示信息,即利用没有定义的组合形式来指示是否允许其他IAB基站的接入,在不影响对UE接入控制的情况下,实现了对IAB基站的单独控制,保证了与现有的通信系统的向下兼容。
需要说明的是,上述仅是以该第一参考条件包括上述几种情况中的至少一种为例进行说明,也即是,这里仅是以当第一参数和第二参数中的至少一个以及第一小区禁止信息满足上述几种情况中的至少一种时,指示信息用于指示允许其他IAB基站接入为例。在另一实施例中,上述几种情况中的至少一种还可以用于指示不允许其他IAB基站接入,也就是说,在具体实施场景中,上述几种组合情况可以根据实际需求来设置以指示是否允许其他IAB基站接入,本申请实施例对此不作限定。
此外,在一些实施例中,当第一参数和第二参数中至少一个的内容以及第一小区禁止信息的内容满足如下2种情况中的至少一种时,该指示信息用于指示允许其他IAB基站接入,其中,所述2种情况包括:1、cellBarred=“not barred”,并且cellReservedForOperatorUse=“not reserved”,以及cellReservedForOtherUse=not“true”;2、cellBarred=“not barred”,并且,cellReservedForOperatorUse=“reserved”,以及cellReservedForOtherUse=not“true”。也就是说,通常情况下,当IAB基站允许UE接入或者允许部分接入类型的UE接入时,默认也允许其他IAB基站接入。
还需要说明的是,上述第一参考条件包括的至少一种情况仅是示例性的,在实施中,在不影响UE 接入的情况下,还可以采用其它组合形式来指示是否允许其他IAB基站接入。
步骤303:第二IAB基站接收系统信息。
在一种可能的实现方式中,当该第一IAB基站采用广播的方式发送该广播信息时,该第二IAB可以采用周期监听的方式接收该广播信息。也即是,可以每隔参考时长,监听第一IAB基站广播的系统信息。该参考时长可以根据实际需求进行设置。
步骤304:第二IAB基站接收广播信息。
同理,当该第一IAB基站采用广播的方式发送广播信息时,该第二IAB基站可以采用周期监听的方式接收该广播信息。也即是,可以每隔参考时长,监听第一IAB基站广播的广播信息。
同理,上述步骤303和步骤304之间没有明确的先后执行顺序,即第二IAB基站可以在不同时刻分别接收该系统信息和该广播信息,或者,也可以同时接收该系统信息和广播信息,本申请实施例对此不作限定。
步骤305:第二IAB基站读取该第一参数和该第二参数中的至少一个以及该第一小区禁止信息,得到该指示信息。
当第一IAB基站采用第一参数和第一小区禁止信息组成该指示信息时,该第二IAB基站读取该第一参数和该第一小区禁止信息。当采用第二参数和第一小区禁止信息组成该指示信息时,该第二IAB基站读取该第二参数和该第一小区禁止信息。当采用第一参数、第二参数和第一小区禁止信息组成该指示信息时,该第二IAB基站读取该第一参数、该第二参数和该第一小区禁止信息。
步骤306:第二IAB基站基于该指示信息,确定是否接入该第一IAB基站。
具体地,当该指示信息指示允许其他IAB基站接入该第一IAB基站时,第二IAB基站确定可以接入该第一IAB基站,否则,当该指示信息指示不允许其他IAB基站接入该第一IAB基站时,该第二IAB基站确定不可以接入该第一IAB基站。
比如,当该指示信息包括cellBarred和cellReservedForOtherUse,并且,该cellBarred="barred",以及cellReservedForOtherUse="true"时,该第二IAB基站确定可以接入该第一IAB基站。
在本申请实施例中,第一IAB基站发送指示信息,由于该指示信息用于指示是否允许其他IAB基站接入该第一IAB基站,因此,第二IAB基站接收该指示信息后,可以确定是否接入该第一IAB基站。如此通过该指示信息单独控制其他IAB基站的接入,即将与对UE的接入分离开分别进行控制,提高了IAB基站的接入控制的灵活性。
请参考图4,该图4是根据另一示例性实施例示出的一种信息指示方法的流程图,该信息指示方法可以包括如下几个实现步骤:
步骤401:第一IAB基站发送广播信息,该广播信息包括主信息块MIB信息,该指示信息位于该MIB信息中。
在一种可能的实现方式,该指示信息位于该MIB信息的空闲比特位中。如前文所述,该MIB信息包括1比特的空闲比特位,因此,可以在该空闲比特位中添加该指示信息。
比如,该指示信息可以表示为cellBarred-IAB。其中,当cellBarred-IAB=“not barred”时,用于指示允许其他IAB基站接入,当该cellBarred-IAB=“barred”时,用于指示不允许其他IAB基站接入。
进一步地,该指示信息在标准中可以定义为:cellBarred-IAB ENUMERATED{barred,notBarred}。
值得一提的是,利用MIB信息中的空闲比特位携带指示信息实现对IAB基站的单独控制,可以减小对通信技术中已使用信息的影响。
当然,上述实现方式仅是示例性的,在另一实施例中,也可以采用该MIB信息中的其它信息作为该指示信息,本申请实施例对此不做限定。
步骤402:第二IAB基站接收该广播信息。
在一种可能的实现方式中,当该第一IAB基站采用广播的方式发送该广播信息时,该第二IAB可以采用周期监听的方式接收该广播信息。也即是,可以每隔参考时长,监听第一IAB基站广播的系统信息。该参考时长可以根据实际需求进行设置。
步骤403:第二IAB基站在该MIB信息中读取该指示信息。
在一些实施例中,当第一IAB基站采用MIB信息中的空闲比特位携带该指示信息时,该第二IAB基站可以从该MIB信息的空闲比特位中读取该指示信息。譬如,读取的指示信息为cellBarred-IAB。
步骤404:第二IAB基站基于该指示信息,确定是否接入该第一IAB基站。
具体地,当该指示信息指示允许其他IAB基站接入该第一IAB基站时,第二IAB基站确定可以接入该第一IAB基站,否则,当该指示信息指示不允许其他IAB基站接入该第一IAB基站时,该第二IAB基站确定不可以接入该第一IAB基站。
比如,当该cellBarred-IAB=“not barred”时,确定可以接入该第一IAB基站,当该cellBarred-IAB=“barred”时,确定不可以接入该第一IAB基站。
在本申请实施例中,第一IAB基站发送指示信息,由于该指示信息用于指示是否允许其他IAB基站 接入该第一IAB基站,因此,第二IAB基站接收该指示信息后,可以确定是否接入该第一IAB基站。如此通过该指示信息单独控制其他IAB基站的接入,即将与对UE的接入分离开分别进行控制,提高了IAB基站的接入控制的灵活性。
请参考图5,该图5是根据另一示例性实施例示出的一种信息指示方法的流程图,该信息指示方法可以包括如下几个实现步骤:
步骤501:第一IAB基站发送系统信息,该系统信息包括第一参数和第二参数,该第一参数用于指示是否保留为运营商使用的小区,该第二参数用于指示是否保留为其他用途使用的小区。
进一步地,该第一IAB基站广播该系统信息,也即是,该第一IAB基站可以采用广播的方式发送该系统信息。其中,该系统信息可以为SIB1信息,在该种情况下,该第一参数可以为cellReservedForOperatorUse,该第二参数可以为cellReservedForOtherUse。
步骤502:第一IAB基站发送广播信息,该广播信息包括主信息块MIB信息,该MIB信息中携带有第二小区禁止信息,该第二小区禁止信息用于指示第一IAB基站是否处于禁止接入状态。
进一步地,该第一IAB基站广播该广播信息,也即是,该第一IAB基站可以采用广播的方法发送广播信息。
需要说明的是,该步骤与步骤501之间没有明确的先后执行顺序,即第一IAB基站可以在不同时刻分别发送该系统信息和该广播信息,或者,也可以同时发送该系统信息和广播信息,本申请实施例对此不作限定。
进一步地,该第二小区禁止信息可以位于该MIB信息的空闲比特位中,也即是,第一IAB基站可以在该MIB信息的空闲比特位中添加第二小区禁止信息,用于指示第一IAB基站是否处于禁止接入状态。譬如,该第二小区禁止信息可以表示为cellBarred-IAB,进一步地,当该cellBarred-IAB=“not barred”时,用于指示该第一IAB基站处于非禁止接入状态,当该cellBarred-IAB=“barred”时,用于指示该第一IAB基站处于禁止接入状态。
其中,该第一参数和该第二参数中的至少一个以及该MIB信息的第二小区禁止信息组成该指示信息。当该第二小区禁止信息指示该第一IAB基站处于禁止接入状态时,该指示信息指示不允许其他IAB基站接入。当该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态,该第一参数和该第二参数中至少一个的内容满足第二参考条件时,该指示信息指示允许其他IAB基站接入;当该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态,该第一参数和该第二参数中至少一个的内容不满足该第二参考条件时,该指示信息指示不允许其他IAB基站接入。
也就是说,当该第二小区禁止信息指示该第一IAB基站处于禁止接入状态时,该指示信息可以指示不允许其他IAB基站接入;而当该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态时,还可以结合第一参数和第二参数中的至少一个来指示是否允许其他IAB基站接入,具体可以根据该第一参数和第二参数中至少一个的内容是否满足第二参考条件来进行指示。
其中,该第二参考条件可以根据实际需求进行设置。在一种可能的实现方式中,该第一参考条件可以包括如下情况中的至少一种:
第一种情况:第一参数指示不保留为运营商使用的小区,第二参数指示不保留为其他用途使用的小区。
第二种情况:第一参数指示保留为运营商使用的小区。
也就是说,在该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态的情况下,当该第一参数和第二参数中至少一个的内容满足上述两种情况中的至少一种时,该指示信息用于指示允许其他IAB基站接入,否则,该指示信息用于指示不允许其他IAB基站接入。
譬如,假设该第二小区禁止信息表示为cellBarred-IAB,该第一参数为cellReservedForOperatorUse,该第二参数为cellReservedForOtherUse。则当cellBarred-IAB=“not barred”,并且,cellReservedForOperatorUse=“not reserved”,以及cellReservedForOtherUse=not“true”时,该指示信息用于指示允许其他IAB基站接入。当cellBarred-IAB=“not barred”,并且,cellReservedForOperatorUse=“reserved”时,该指示信息也可以用于指示允许其他IAB基站接入。否则,对于其他种情况,该指示信息用于指示不允许其他IAB基站接入。
值得一提的是,这里基于第二小区禁止信息,结合第一参数和第二参数中的至少一个组成指示信息,兼容了当前已有的通信技术,减小了运算代价。
步骤503:第二IAB基站接收该系统信息。
在一种可能的实现方式中,当该第一IAB基站采用广播的方式发送系统信息时,该第二IAB基站可以采用周期监听的方式接收该系统信息。也即是,可以每隔参考时长,监听第一IAB基站广播的系统信息。该参考时长可以根据实际需求进行设置。
步骤504:第二IAB基站接收该广播信息。
同理,当该第一IAB基站采用广播的方式发送广播信息时,该第二IAB基站可以采用周期监听的方 式接收该广播信息。也即是,可以每隔参考时长,监听第一IAB基站广播的广播信息。该参考时长可以根据实际需求进行设置。
同理,该步骤504与上述步骤503之间也没有明确的先后执行顺序,即第二IAB基站可以在不同时刻分别接收该系统信息和该广播信息,或者,也可以同时接收该系统信息和广播信息,本申请实施例对此不作限定。
步骤505:第二IAB基站至少读取该MIB信息的第二小区禁止信息,得到该指示信息。
具体地,第二IAB基站读取该MIB信息的第二小区禁止信息,得到该指示信息。当该第二小区禁止信息指示该第一IAB基站处于禁止接入状态时,确定该指示信息指示不允许其他IAB基站接入;当该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态时,继续读取该第一参数和该第二参数中的至少一个,得到该指示信息。
由于当该第二小区禁止信息指示该第一IAB基站处于禁止接入状态时,可以直接确定该指示信息指示不允许其他IAB基站接入,即无需读取系统信息中的两个参数,而当该第二小区禁止信息指示该第一IAB基站处于非禁止接入状态时,需要继续读取系统信息中的第一参数和第二参数,因此,对于该第二IAB基站来说,至少读取该MIB信息的第二小区禁止信息,也即是,必须读取第二小区禁止信息,至于是否需要读取第一参数和第二参数中的至少一个,需要根据该第二小区信息的指示来确定。
值得一提的是,当该第二小区禁止信息指示该第一IAB基站处于禁止接入状态,只需要读取第二小区禁止信息即可确定第一IAB是否允许其他IAB接入,如此,减少了读取的次数,降低了基站的功耗。
步骤506:第二IAB基站基于该指示信息,确定是否接入该第一IAB基站。
具体地,当该指示信息指示允许其他IAB基站接入该第一IAB基站时,第二IAB基站确定可以接入该第一IAB基站,否则,当该指示信息指示不允许其他IAB基站接入该第一IAB基站时,该第二IAB基站确定不可以接入该第一IAB基站。
譬如,当该指示信息包括第二小区禁止信息cellBarred-IAB、第一参数cellReservedForOperatorUse以及第二参数cellReservedForOtherUse时,如果cellBarred-IAB=“not barred”,并且,cellReservedForOperatorUse=“not reserved”,以及cellReservedForOtherUse=not“true”,则确定可以接入第一IAB基站。
在本申请实施例中,第一IAB基站发送指示信息,由于该指示信息用于指示是否允许其他IAB基站接入该第一IAB基站,因此,第二IAB基站接收该指示信息后,可以确定是否接入该第一IAB基站。如此通过该指示信息单独控制其他IAB基站的接入,即将与对UE的接入分离开分别进行控制,提高了IAB基站的接入控制的灵活性。
请参考图6,该图6是根据另一示例性实施例示出的一种信息指示方法的流程图,该信息指示方法可以包括如下几个实现步骤:
步骤601:第一IAB基站发送广播信息,该广播信息包括除MIB信息之外的附加比特位,该指示信息位于该附加比特位中。
在一种可能的实现方式中,该第一IAB基站发送该广播信息的具体实现可以包括:该第一IAB基站广播该广播信息。也就是说,该第一IAB基站可以采用广播的方式发送该广播信息。
在一些实施例中,该指示信息位于该PBCH信道承载的信息中。其中,该附加比特位为PBCH信道的层1的8比特信息所在的比特位,相应地,该指示信息位于该PBCH信道承载的层1的8比特信息中。
进一步地,当该第一IAB基站的系统频带带宽小于参考频带阈值时,该指示信息可以位于该附加比特位的保留比特位中。如前文所述,由于当该第一IAB基站的系统频带带宽小于参考频带阈值时,该附加比特位中包括2比特的保留比特位,因此,可以在该保留比特位中添加该指示信息。
譬如,该指示信息可以表示为cellBarred-IAB。在一种可能的实现方式中,当cellBarred-IAB=“not barred”时,用于指示允许其他IAB基站接入,当该cellBarred-IAB=“barred”时,用于指示不允许其他IAB基站接入。
进一步地,在标准中可以定义为:cellBarred-IAB ENUMERATED{barred,notBarred}。
其中,上述参考频带阈值可以根据实际需求进行设置,比如该参考频带阈值可以为6GHz等。
值得一提的是,利用附加比特位中的空闲比特位携带指示信息实现对IAB基站的单独控制,可以减小对通信技术已使用的信息的影响。
需要说明的是,上述是以在保留比特位中添加该指示信息为例进行说明,在另一实施例中,还可以使用附加比特位上通信技术已使用的信息来作为该指示信息,本申请实施例对此不做限定。
步骤602:第二IAB基站接收该广播信息。
在一种可能的实现方式中,当该第一IAB基站采用广播的方式发送该广播信息时,该第二IAB可以采用周期监听的方式接收该广播信息。也即是,可以每隔参考时长,监听第一IAB基站广播的系统信息。该参考时长可以根据实际需求进行设置。
步骤603:第二IAB基站在该附加比特位中读取该指示信息。
进一步地,当第一IAB基站采用附加比特位的保留比特位携带该指示信息时,该第二IAB基站可以从该附加比特位的保留比特位中读取该指示信息。譬如,读取的指示信息为cellBarred-IAB。
步骤604:第二IAB基站基于该指示信息,确定是否接入该第一IAB基站。
具体地,当该指示信息指示允许其他IAB基站接入该第一IAB基站时,第二IAB基站确定可以接入该第一IAB基站,否则,当该指示信息指示不允许其他IAB基站接入该第一IAB基站时,该第二IAB基站确定不可以接入该第一IAB基站。
比如,当该cellBarred-IAB=“not barred”时,确定可以接入该第一IAB基站,当该cellBarred-IAB=“barred”时,确定不可以接入该第一IAB基站。
在本申请实施例中,第一IAB基站发送指示信息,由于该指示信息用于指示是否允许其他IAB基站接入该第一IAB基站,因此,第二IAB基站接收该指示信息后,可以确定是否接入该第一IAB基站。如此通过该指示信息单独控制其他IAB基站的接入,即将与对UE的接入分离开分别进行控制,提高了IAB基站的接入控制的灵活性。
需要说明的是,图6所示实施例是以通过PBCH承载的附加比特位携带指示信息为例进行说明,在另一实施例中,第一IAB基站还可以在PBCH承载的附加比特位添加第三小区禁止信息,并结合系统信息的第一参数和第二参数作为指示信息。在实施中,第一IAB基站发送系统信息,以及发送广播信息,该广播信息的附加比特位包括第三小区禁止信息,该系统信息中的第一参数和第二参数中的至少一个以及该第三小区禁止信息组成该指示信息。此时,当该第三小区禁止信息指示该第一IAB基站处于禁止接入状态时,该指示信息指示不允许其他IAB基站接入。否则,当该第三小区禁止信息指示该第一IAB基站处于非禁止接入状态时,可以结合第一参数和第二参数中的至少一个来指示是否允许其他IAB基站接入,具体实现与图5实施例中通过第一参数和第二参数中的至少一个以及第二小区禁止信息指示是否允许其他IAB基站接入类似。
对应的,对于第二IAB来说,接收系统信息以及接收广播信息,至少读取该MIB信息中的第三小区禁止信息,得到该指示信息。具体地,第二IAB基站读取MIB信息的第三小区禁止信息,当该第三小区禁止信息指示该第一IAB基站处于禁止接入状态时,确定该指示信息指示不允许其他IAB基站接入;当该第三小区禁止信息指示该第一IAB基站处于非禁止接入状态时,继续读取第一参数和第二参数中的至少一个,以得到该指示信息,即结合第一参数和第二参数中的至少一个来确定第一IAB基站是否允许其他IAB基站接入。
另外还需要说明的是,在上述几个实施例中是采用通信技术中已使用的信息来携带指示信息,在另一实施例中,还可以定义新的高层信令用于指示是否允许其他AIB基站接入。例如,定义的新的高层信令可以承载在SIB1等信息中,进一步地,可以引入参数cellBarredForIAB、cellReservedForOperatorUseForIAB和cellReservedForOtherUseForIAB,以通过该三个参数组成指示信息。其中,该cellBarredForIAB可以用于指示小区的接入控制状态,该cellReservedForOperatorUseForIAB可以用于指示是否保留为运营商使用的小区,该cellReservedForOtherUseForIAB可以用于指示是否保留为其他用途使用的小区。
值得说明的是,前述各个实施例中的参考时长可以相同也可以不同,本发明实施例对此不做限定。前述各个实施例中,虽然增加了指示信息来指示是否允许其他IAB基站接入,但是该指示信息并未对UE的接入产生影响,从而保证了对其他IAB基站的接入以及对UE的接入的分别控制,实现了与现有的通信系统的向下兼容。
