请参考图1,其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示,无线通信***是基于蜂窝移动通信技术的通信***,该无线通信***可以包括:若干个终端11以及若干个基站12。
其中,终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端11可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment,UE)。或者,终端11也可以是无人飞行器的设备。或者,终端11也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线通信设备。或者,终端11也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信***中的网络侧设备。其中,该无线通信***可以是***移动通信技术(the 4th generation mobile communication,4G)***,又称长期演进(Long Term Evolution,LTE)***;或者,该无线通信***也可以是5G***,又称新空口(new radio,NR)***或5G NR***。或者,该无线通信***也可以是5G***的再下一代***。其中,5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。或者,MTC***。
其中,基站12可以是4G***中采用的演进型基站(eNB)。或者,基站12也可以是5G***中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于***移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的 更下一代移动通信网络技术标准的无线空口。
在一些实施例中,终端11之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。
在一些实施例中,上述无线通信***还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中,网络管理设备13可以是无线通信***中的核心网设备,比如,该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备13的实现形态,本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于:采用蜂窝移动通信网络技术进行无线通信的手机终端等用户设备(UE,User Equipment),以及基站等接入网设备。
本公开实施例的一个应用场景为,在NR中,主同步信号(PSS,Primary Synchronization Signal)、辅同步信号(SSS,Secondary Synchronization Signal),和物理广播信道(PBCH,Physical Broadcast Channel)被称为同步信号/广播信号块(SS/PBCH block,Synchronization Signal/PBCH block)。本实施例为描述方便,把SS/PBCH block称为SSB。
5G蜂窝移动通信***允许采用NR unlicensed技术,即在非授权频谱上使用NR技术进行通信。针对NRU,引入了SSB候选位置(Candidate Position)概念,在每个SSB周期内的SSB发送半帧内,会存在多个SSB候选位置,SSB候选位置为接入网设备可能会发送SSB的时域位置。
为了支持波束扫描,SSB被组织成一系列脉冲串(Burst),并周期性发送。每个SSB周期内发送的多个SSB组成一个Burst,这多个SSB可以从0开始升序编号。一个Burst中的SSB的数量可以与基站采用的波束的数量相同,一个Burst中的各SSB分别采用不同的波束发送。
在120kHz SCS情况下,Case D类型的64个SSB候选位置已经占用了整个半帧,如果由于基站进行LBT失败而无法发送某一个或多个SSB,那么在该半帧所属的SSB周期内,基站将无法发送未发送的SSB,一个或多个波束覆盖范围内UE将无法接收到SSB。
因此,如何提高在120kHz SCS情况下SSB发送的可靠性是亟待解决的问题。
如图2所示,本示例性实施例提供一种信息传输方法,信息传输方法可以应用于无线通信的接入网设备中,包括:
步骤201:在一个SSB周期中的一个无线帧时长内的M个第一类候选位置发送SSB,其中,所述无线帧时长内还包括N个第二类候选位置,其中,所述第二类候选位置用于发送在所述第一类候选位置未发送的所述SSB,M小于或等于64,并且M小于或等于N,M和N均为正整数。
接入网设备可以包括基站等。相关技术中,接入网设备在一个SSB周期中的半帧发送SSB。示例性的,在120kHz SCS下,一个半帧最大可以具有64个发送SSB的候选位置。如果接入网设备需要发送64个SSB,并且由于特定原因有一个或多个SSB未发送,那么在一个SSB周期中,将没有用于重发未发送SSB的候选位置。
这里,可以由通信协议规定、或者由接入网设备与UE商定等,在一个SSB周期中,在一个无线帧时长内发送SSB。在120kHz SCS下,一个半帧 最大可以具有128个候选位置。可以将候选位置分为第一类候选位置和第二类候选位置。第一类候选位置可以用于正常发送SSB,第二类候选位置可以用于发送在第一类候选位置未发送的SSB。
UE可以在第一类候选位置接收正常发送的SSB。针对在第一类候选位置未接收到的SSB,可以在第二类候选位置进行检测并接收。
这里,第一类候选位置和第二类候选位置的时域位置不同。
示例性的,在120kHz SCS下,一个无线帧时长内最大可以具有64个第一类候选位置,和64个第二类候选位置。
在不同的SCS下,每个半帧可以发送的SSB的最大数量不同,即半帧内SSB候选位置数量不同。本实施例提供的方法可以应用但不限于120kHz的SSB SCS情况。不同的SCS包括:15kHz、30kHz、120kHz、240kHz、480kHz等。
可选的,第一类候选位置的数量M可以选择64、32或16等。对应的,第二类候选位置的数量N可以选择64、32或16等。如此,一个第一类候选位置可以关联于一个第二类候选位置,使得一个SSB具有一次重发机会,提高了SSB发送可靠性。
在一个实施例中,M等于N。
示例性的,针对120kHz SCS的情况,最多可以发送64个SSB,M和N可以都等于64,如此,每个SSB都对应于一个可以重发的第二类候选位置。如此,每个第一类候选位置对应于一个第二类候选位置,即每个SSB都有一个机会可以重发。提高了接入网设备发送SSB和UE接收SSB的可靠性。
在一个实施例中,所述第二类候选位置,用于发送在所述第一类候选位置因信道探测失败未发送的所述SSB。
可以选的,未发送成功的SSB,可以是由于接入网设备LBT失败等原 因,未发送的SSB。采用非授权频段进行通信时,接入网设备在发送SSB之前,可以对信道进行监听,如果监听到信道空闲,则在第一类候选位置发送SSB。如果监听到信道被占用,则不在第一类候选位置发送SSB。未发送的SSB可以在第一类候选位置关联的第二类候选位置发送。
如此,通过在一个无线帧时长内的M个第一类候选位置发送SSB,并在N个第二类候选位置发送未发送成功的SSB。扩展了接入网设备发送SSB的时间窗口,即UE接收SSB的时间窗口,使得每个SSB都具有重发的机会,提高了接入网设备发送SSB和UE接收SSB的可靠性。
在一个实施例中,所述在一个SSB周期中的一个无线帧时长内的M个第一类候选位置发送SSB,包括:
在一个SSB周期内的两个半帧分别关联的M/2个第一类候选位置发送所述SSB,其中,一个所述半帧包括第一时域范围和第二时域范围,其中,第一时域范围内具有M/2个所述第一类候选位置,第二时域范围内具有N/2个第二类候选位置,其中,所述第二类候选位置用于发送在同一所述半帧内所述第一类候选位置未发送的所述SSB,其中,所述半帧的时长为所述无线帧时长的1/2。
一个无线帧的时长可以是10ms,那么一个半帧的时长可以是5ms,一个半帧可以包括第一时域范围和第二时域范围,第一时域范围可以位于第二时域范围之前,并且第一时域范围和第二时域范围不具有重复范围。例如,第一时域范围是半帧的前2.5ms,第二时域范围是半帧的后2.5ms。
这里,可以在一个SSB周期中设置两个半帧。接入设备可以在该两个半帧中发送SSB。
第一时域范围的第一类候选位置用于正常发送SSB。每个第一类型候选位置可以在第二时域范围内对应有至少一个第二类型候选位置。
可选的,第二类型候选位置可以至少用于发送在关联的第一类型候选 位置未发送成功的SSB。
示例性的,在120kHz SCS下,一个半帧最大可以具有32个第一类候选位置,和32个第二类候选位置。
在一个实施例中,所述第二类候选位置,用于发送在所述第一类候选位置因信道探测失败未发送的所述SSB。
可以选的,未发送成功的SSB,可以是由于接入网设备LBT失败等原因,未发送的SSB。采用非授权频段进行通信时,接入网设备在发送SSB之前,可以对信道进行监听,如果监听到信道空闲,则在第一类候选位置发送SSB。如果监听到信道被占用,则不在第一类候选位置发送SSB。未发送的SSB可以在第一类候选位置关联的第二类候选位置发送。
在120kHz SCS情况下,一个半帧一共可以设置有64个候选位置,为满足一个第一类候选位置具有一个关联的第二类候选位置,因此,第一类候选位置最多可以设置32个,对应于32个第一类候选位置,可以设置有32个第二类候选位置。
在一个半帧内,第二类候选位置用于由接入网设备发送本半帧的第一类候选位置未发送的SSB。
可选的,一个半帧内,第一类候选位置的数量M/2可以选择32、16或8等。对应的,在该半帧内,第二类候选位置的数量N/2可以选择32、16或8等。如此,一个第一类候选位置可以关联于所属半帧内的一个第二类候选位置,使得一个SSB在半帧内具有一次重发机会,提高了SSB发送可靠性。
在一个实施例中,在一个所述SSB周期中,每个第一类候选位置关联于一个波束。
当接入网设备通过波束扫描方式发送信号时,接入网设备在一个通过一个波束发送一个SSB。针对120kHz SCS的情况,接入网设备最多可以在 64个波束内发送SSB,即SSB的索引从0至63。
在64个波束中发送SSB,则需要64个第一类候选位置。
由于一个SSB周期中具有两个半帧,每个半帧的第一类候选位置最多可以发送32个SSB,因此,两个半帧可以最多发送64个SSB,并且两个半帧的第二类候选位置可以为每个第一类候选位置提供一次重发的机会。
针对120kHz SCS Case D的情况,在一个SSB周期内最多需要发送64个SSB,采用本实施例提供的方法,可以在一个SSB周期内发送64个SSB,并且针对每个SSB均可以设置有第二类候选位置用于重发。减少由于LBT失败未发送SSB时,没有重发机会的情况。提高了SSB发送的可靠性。
在一个实施例中,如图3所示,所述方法还包括:
步骤202:在所述第二类候选位置发送在所述第二类候选位置关联的所述第一类候选位置未发送的所述SSB。
当接入网设备可以第一时域范围的第一类候选位置发送SSB。如果由于LBT失败等原因,接入网设备在第一时域范围的一个或多个第一类候选位置未发送SSB。可以在第二时域范围的一个或多个第二类候选位置发送未发送的SSB。
UE可以在第一类候选位置接收正常发送的SSB。如果有在第一类候选位置未接收的SSB,则UE可以在该第一类候选位置关联的第二类候选位置再次接收SSB。
可选的,第一类候选位置关联第二类候选位置,可以是第一类候选位置在第一时域范围的位次与第二类候选位置在第二时域范围的位次相同。例如,第一时域范围的第一个第一类候选位置关联于第二时域范围的第一个第二类候选位置。或者,当一个第一类候选位置关联于多个第二类候选位置时,M/2个第一类候选位置可以划分为一组,针对一组M/2个第一类候选位置,在第二时域范围内具有多组M/2个第二类候选位置,第一类候 选位置对应的第二类候选位置在组内的位次相同。
示例性的,一个第一类候选位置对应的第二类候选位置在各自所属分组内的位次可以相同。例如:某第一类候选位置位于第一类候选位置分组的第j位,则第二类候选位置的一个或多个分组内的第j位均为该第一类候选位置所关联的第二类候选位置。
如此,针对120kHz SCS Case D的情况,在一个SSB周期内设置两个半帧,在一个半帧内、在第二类候选位置发送在第一类候选位置未发送成功的SSB,一方面,可以在一个SSB周期内可以发送最多64个SSB,另一方面,使得未发送成功的SSB可以进行重发,增加接入网设备发送SSB的机会,进而增加了UE接收SSB的机会,从而提高了接入网设备发送SSB的可靠性。
在一个实施例中,接入网设备可以通过下行指示信息向UE指示一个SSB周期中是否有两个半帧。
当指示信息指示SSB周期中有两个半帧时,UE基于两个半帧接收SSB。
当指示信息指示SSB周期没有两个半帧时,UE可以采用相关技术的方式在一个半帧中接收SSB。
在一个实施例中,所述SSB周期包括:第一SSB子周期和第二SSB子周期;其中,两个所述半帧分别位于所述第一SSB子周期和所述第二SSB子周期内。
可选的,可以在一个SSB周期中设置两个SSB子周期:第一SSB子周期和所述第二SSB子周期。UE可以以子周期为单位监听SSB。每个SSB子周期可以设置有一个半帧用于发送SSB。
在一个实施例中,接入网设备可以通过下行指示信息向UE指示一个SSB周期中是否有两个SSB子周期,即指示是否有两个半帧。
当指示信息指示SSB周期中有两个SSB子周期时,UE基于两个SSB 子周期接收SSB。
当指示信息指示SSB周期没有两个SSB子周期时,UE可以采用相关技术的方式在一个SSB周期中接收SSB,不再通过两个SSB子周期搜索SSB。
在一个实施例中,所述第一SSB子周期的时长和所述第二SSB子周期的时长相同。
示例性的,接入网设备可以配置SSB子周期。例如,针对初始接入的SSB周期,可以设置第一SSB子周期和第二SSB子周期可以均为10m等。
在一个实施例中,所述第一SSB子周期的时长和所述第二SSB子周期的时长均为所述SSB周期的时长的1/2。
示例性的,接入网设备可以配置SSB周期,对于初始接入默认的SSB周期为20ms,那么第一SSB子周期和第二SSB子周期可以均为10m。
接入网设备可以在第一SSB子周期,即第一个10ms内的半帧的第一类候选位置发送32个SSB,以及在第一SSB子周期,即第一个10ms内半帧的第二类候选位置发送该32个SSB中未发送的SSB。
接入网设备可以在第二SSB子周期,即第二个10ms内的半帧的第一类候选位置发送剩余的32个SSB,以及在第二SSB子周期,即第二个10ms的半帧的第二类候选位置发送剩余32个SSB中未发送的SSB。
在一个实施例中,所述第一时域范围的时长和所述第二时域范围的时长相同。
这里,一个半帧可以包括第一时域范围和第二时域范围,半帧占用的时长为5ms,第一时域范围的时长和第二时域范围的时长可以均为2.5ms。
示例性的,第一SSB子周期和第二SSB子周期可以均为10ms。
接入网设备可以在第一个10ms内的半帧的第一时域范围,即前2.5ms的第一类候选位置发送32个SSB,以及在第一个10ms内的半帧的第二时 域范围,即后2.5ms的第二类候选位置发送该32个SSB中未发送的SSB。
接入网设备可以在第二个10ms内的半帧的第一时域范围,即前2.5ms第一类候选位置发送剩余的32个SSB,以及在第二个10ms内的半帧的第二时域范围,即后2.5ms的第二类候选位置发送剩余32个SSB中未发送的SSB。
在一个实施例中,UE响应于M和N均等于64,并且在所述第一SSB子周期的所述半帧的第二类候选位置接收到的所述SSB的索引号小于或等于31,UE可以确定接入网设备发送的SSB数量大于32。
第一SSB子周期可以用于发送索引为0至31的SSB,第二SSB子周期可以用于发送索引为32至63的SSB。
当在第一SSB子周期的半帧的第二类候选位置接收到的所述SSB的索引号小于或等于31,则可以确定第一SSB子周期只用于发送32个SSB,并且接入网设备会通过两个SSB子周期发送SSB,即发送的SSB大于32,如64个。UE需要在第二SSB子周期接收剩余的SSB。
在一个实施例中,UE响应于M和N均等于64,并且在所述第二SSB子周期的所述半帧的第一类候选位置接收到的所述SSB的索引号大于或等于32,UE确定接入网设备发送的SSB数量大于32。
第一SSB子周期可以用于发送索引为0至31的SSB,第二SSB子周期可以用于发送索引为32至63的SSB。
当UE在第二SSB子周期的半帧的第二类候选位置接收到的所述SSB的索引号大于或等于31,则可以确定第一SSB子周期和第二SSB子周期发送的SSB数量大于32个。
如图4所示,本示例性实施例提供一种信息传输方法,信息传输方法可以应用于无线通信的用户设备UE中,包括:
步骤401:在一个SSB周期中的一个无线帧时长内的M个第一类候选 位置接收SSB,其中,所述无线帧时长内还包括N个第二类候选位置,其中,所述第二类候选位置用于接收在所述第一类候选位置未接收到的所述SSB,M小于或等于64,并且M小于或等于N,M和N均为正整数。
这里,可以由基站等接入网设备发送SSB,由手机终端等UE接收SSB。。相关技术中,接入网设备在一个SSB周期中的半帧发送SSB,UE在一个SSB周期中的半帧监听并接收SSB。示例性的,在120kHz SCS下,一个半帧最大可以具有64个发送SSB的候选位置。如果接入网设备需要发送64个SSB,并且由于特定原因有一个或多个SSB未发送,那么在一个SSB周期中,将没有用于重发未发送SSB的候选位置,即如果UE在一个SSB周期内对应的资源上没有接收到SSB,则在该SSB周期内不会在接收到SSB。
这里,可以由通信协议规定、或者由接入网设备与UE商定等,UE在一个一个SSB周期中在一个无线帧时长内接收SSB。在120kHz SCS下,一个半帧最大可以具有128个候选位置。可以将候选位置分为第一类候选位置和第二类候选位置。第一类候选位置可以用于正常接收SSB,第二类候选位置可以用于接收在第一类候选位置未接收到的SSB。
UE可以在第一类候选位置接收正常发送的SSB。针对在第一类候选位置未接收到的SSB,可以在第二类候选位置进行检测并接收。
这里,第一类候选位置和第二类候选位置的时域位置不同。
示例性的,在120kHz SCS下,一个无线帧时长内最大可以具有64个第一类候选位置,和64个第二类候选位置。
在不同的SCS下,每个半帧可以接收的SSB的最大数量不同,即半帧内SSB候选位置数量不同。本实施例提供的方法可以应用但不限于120kHz的SSB SCS情况。不同的SCS包括:15kHz、30kHz、120kHz、240kHz、480kHz等。
可选的,第一类候选位置的数量M可以选择64、32或16等。对应的, 第二类候选位置的数量N可以选择64、32或16等。如此,一个第一类候选位置可以关联于一个第二类候选位置,使得一个SSB具有一次重发机会,提高了SSB发送可靠性。
在一个实施例中,M等于N。
示例性的,针对120kHz SCS的情况,一个SSB周期内最多可以发送64个SSB,M和N可以都等于64,如此,每个SSB都对应于一个可以重发的第二类候选位置。如此,每个第一类候选位置对应于一个第二类候选位置,即每个SSB接入网设备都有一个机会可以重发;每个未发送的SSB,UE都可以在第二类候选位置上进行接收。提高了接入网设备发送SSB和UE接收SSB的可靠性。
在一个实施例中,所述第二类候选位置,用于接收在所述第一类候选位置因信道探测失败未接收的所述SSB。
可以选的,未接收成功的SSB,可以是由于接入网设备LBT失败等原因,未发送的SSB。采用非授权频段进行通信时,接入网设备在发送SSB之前,可以对信道进行监听,如果监听到信道空闲,则在第一类候选位置发送SSB。如果监听到信道被占用,则接入网设备不在第一类候选位置发送SSB。未发送的SSB可以在第一类候选位置关联的第二类候选位置发送。
UE在接收SSB时,会首先在第一类候选位置进行检测并接收SSB。如果在一个或多个第一类候选位置上未检测到SSB,UE可以在第一类候选位置关联的第二类候选位置上进行检测接入网设备重发的SSB。
示例性的,接入网设备在进行LBT时,发现第一类候选位置A和第一类候选位置B的资源被占用,则不在第一类候选位置A和第一类候选位置B发送SSB。UE检测第一类候选位置A和第一类候选位置B时未检测到SSB。接入网设备分别可以在第一类候选位置A关联的第二类候选位置A,以及第一类候选位置B关联的第二类候选位置B重发SSB,UE可以通过 检测第二类候选位置A和第二类候选位置B分别检测到重发的SSB。
如此,通过在一个无线帧时长内的M个第一类候选位置发送SSB,并在N个第二类候选位置发送未发送成功的SSB。扩展了接入网设备发送SSB的时间窗口,即UE接收SSB的时间窗口,使得每个SSB都具有重发的机会,提高了接入网设备发送SSB和UE接收SSB的可靠性。
在一个实施例中,所述在一个SSB周期中的一个无线帧时长内的M个第一类候选位置接收SSB,包括:
在一个SSB周期内的两个半帧分别关联的M/2个第一类候选位置接收所述SSB,其中,一个所述半帧包括第一时域范围和第二时域范围,其中,第一时域范围内具有M/2个所述第一类候选位置,第二时域范围内具有N/2个第二类候选位置,其中,所述第二类候选位置用于接收在同一所述半帧内所述第一类候选位置未接收的所述SSB,其中,所述半帧的时长为所述无线帧时长的1/2。
一个无线帧的时长可以是10ms,那么一个半帧的时长可以是5ms,一个半帧可以包括第一时域范围和第二时域范围,第一时域范围可以位于第二时域范围之前,并且第一时域范围和第二时域范围不具有重复范围。例如,第一时域范围是半帧的前2.5ms,第二时域范围是半帧的后2.5ms。
这里,可以在一个SSB周期中设置两个半帧。接入设备可以在该两个半帧中发送SSB,UE则在该两个半帧中接收SSB。
第一时域范围的第一类候选位置用于由UE正常接收SSB。每个第一类型候选位置可以在第二时域范围内对应有至少一个第二类型候选位置。
可选的,第二类型候选位置可以至少用于由UE接收在关联的第一类型候选位置未接收成功的SSB。
示例性的,在120kHz SCS下,一个半帧最大可以具有32个第一类候选位置,和32个第二类候选位置。
在120kHz SCS情况下,一个半帧一共可以设置有64个候选位置,为满足一个第一类候选位置具有一个关联的第二类候选位置,因此,第一类候选位置最多可以设置32个,对应于32个第一类候选位置,可以设置有32个第二类候选位置。
在一个半帧内,第二类候选位置用于由UE接收本半帧的第一类候选位置未接收的SSB。
可选的,一个半帧内,第一类候选位置的数量M/2可以选择32、16或8等。对应的,在该半帧内,第二类候选位置的数量N/2可以选择32、16或8等。如此,一个第一类候选位置可以关联于所属半帧内的一个第二类候选位置,使得一个SSB在半帧内具有一次重新接收机会,提高了SSB接收可靠性。
在一个实施例中,在一个所述SSB周期中,每个第一类候选位置关联于一个波束。
当接入网设备通过波束扫描方式发送信号时,接入网设备在一个通过一个波束发送一个SSB。针对120kHz SCS的情况,接入网设备最多可以在64个波束内发送SSB,即SSB的索引从0至63。
属于一个波束覆盖范围的UE可以接收在波束对应的第一类候选位置发送的SSB。相应的,属于一个波束覆盖范围的UE可以接收在波束对应的第二类候选位置重新发送的SSB。
在64个波束中发送SSB,则需要64个第一类候选位置。
由于一个SSB周期中具有两个半帧,每个半帧的第一类候选位置最多可以接收32个SSB,因此,两个半帧可以最多接收64个SSB,并且两个半帧的第二类候选位置可以为每个第一类候选位置提供一次重新接收的机会。
针对120kHz SCS Case D的情况,在一个SSB周期内最多需要接收64 个SSB,采用本实施例提供的方法,可以在一个SSB周期内接收64个SSB,并且针对每个SSB均可以设置有第二类候选位置用于重新接收。减少由于LBT失败未发送SSB时,没有重新接收的机会的情况。提高了SSB接收的可靠性。
在一个实施例中,如图5所示,所述方法还包括:
步骤402:在所述第二类候选位置接收在所述第二类候选位置关联的所述第一类候选位置未接收的所述SSB。
当接入网设备可以第一时域范围的第一类候选位置发送SSB。如果由于LBT失败等原因,接入网设备在第一时域范围的一个或多个第一类候选位置未发送SSB。可以在第二时域范围的一个或多个第二类候选位置发送未发送的SSB。
UE可以在第一类候选位置接收正常发送的SSB。如果有在第一类候选位置未接收的SSB,则UE可以在该第一类候选位置关联的第二类候选位置再次接收SSB。
可选的,第一类候选位置关联第二类候选位置,可以是第一类候选位置在第一时域范围的位次与第二类候选位置在第二时域范围的位次相同。例如,第一时域范围的第一个第一类候选位置关联于第二时域范围的第一个第二类候选位置。或者,当一个第一类候选位置关联于多个第二类候选位置时,M/2个第一类候选位置可以划分为一组,针对一组M/2个第一类候选位置,在第二时域范围内具有多组M/2个第二类候选位置,第一类候选位置对应的第二类候选位置在组内的位次相同。
示例性的,一个第一类候选位置对应的第二类候选位置在各自所属分组内的位次可以相同。例如:某第一类候选位置位于第一类候选位置分组的第j位,则第二类候选位置的一个或多个分组内的第j位均为该第一类候选位置所关联的第二类候选位置。
如此,针对120kHz SCS Case D的情况,在一个SSB周期内设置两个半帧,在一个半帧内、在第二类候选位置发送在第一类候选位置未接收成功的SSB,一方面,UE可以在一个SSB周期内可以接收最多64个SSB,另一方面,UE可以对未接收成功的SSB进行重新接收,增加接入网设备发送SSB的机会,进而增加了UE接收SSB的机会,从而提高了UE接收SSB的可靠性。
在一个实施例中,接入网设备可以通过下行指示信息向UE指示一个SSB周期中是否有两个半帧。
当指示信息指示SSB周期中有两个半帧时,UE基于两个半帧接收SSB。
当指示信息指示SSB周期没有两个半帧时,UE可以采用相关技术的方式在一个半帧中接收SSB。
在一个实施例中,所述SSB周期包括:第一SSB子周期和第二SSB子周期;其中,两个所述半帧分别位于所述第一SSB子周期和所述第二SSB子周期内。
可选的,可以在一个SSB周期中设置两个SSB子周期:第一SSB子周期和所述第二SSB子周期。UE可以以子周期为单位监听SSB。每个SSB子周期可以设置有一个半帧用于发送SSB。
在一个实施例中,接入网设备可以通过下行指示信息向UE指示一个SSB周期中是否有两个SSB子周期,即指示是否有两个半帧。
当指示信息指示SSB周期中有两个SSB子周期时,UE基于两个SSB子周期接收SSB。
当指示信息指示SSB周期没有两个SSB子周期时,UE可以采用相关技术的方式在一个SSB周期中接收SSB,不再通过两个SSB子周期搜索SSB。
在一个实施例中,所述第一SSB子周期的时长和所述第二SSB子周期 的时长相同。
示例性的,接入网设备可以配置SSB子周期。例如,针对初始接入的SSB周期,可以设置第一SSB子周期和第二SSB子周期可以均为10m等。
在一个实施例中,所述第一SSB子周期的时长和所述第二SSB子周期的时长均为所述SSB周期的时长的1/2。
示例性的,接入网设备可以配置SSB周期,对于初始接入默认的SSB周期为20ms,那么第一SSB子周期和第二SSB子周期可以均为10m。
UE可以在第一SSB子周期,即第一个10ms内的半帧的第一类候选位置接收32个SSB,以及在第一SSB子周期,即第一个10ms内半帧的第二类候选位置接收该32个SSB中未接收的SSB。UE可以在第二SSB子周期,即第二个10ms内的半帧的第一类候选位置接收剩余的32个SSB,以及在第二SSB子周期,即第二个10ms的半帧的第二类候选位置接收剩余32个SSB中未接收的SSB。
在一个实施例中,所述第一时域范围的时长和所述第二时域范围的时长相同。
这里,一个半帧可以包括第一时域范围和第二时域范围,半帧占用的时长为5ms,第一时域范围的时长和第二时域范围的时长可以均为2.5ms。
示例性的,第一SSB子周期和第二SSB子周期可以均为10ms。
UE可以在第一个10ms内的半帧的第一时域范围,即前2.5ms的第一类候选位置接收32个SSB,以及在第一个10ms内的半帧的第二时域范围,即后2.5ms的第二类候选位置接收该32个SSB中未接收的SSB。
UE可以在第二个10ms内的半帧的第一时域范围,即前2.5ms第一类候选位置接收剩余的32个SSB,以及在第二个10ms内的半帧的第二时域范围,即后2.5ms的第二类候选位置接收E剩余32个SSB中未接收的SSB。
在一个实施例中,所述第一SSB子周期的时域位置在所述第二SSB子 周期的时域位置之前,所述方法还包括:
响应于M和N均等于64,并且在所述第一SSB子周期的所述半帧的第二类候选位置接收到的所述SSB的索引号小于或等于31,确定接入网设备发送的SSB数量大于32。
第一SSB子周期可以用于发送索引为0至31的SSB,第二SSB子周期可以用于发送索引为32至63的SSB。
当在第一SSB子周期的半帧的第二类候选位置接收到的所述SSB的索引号小于或等于31,则可以确定第一SSB子周期只用于发送32个SSB,并且接入网设备会通过两个SSB子周期发送SSB,即发送的SSB大于32,如64个。UE需要在第二SSB子周期接收剩余的SSB。
在一个实施例中,所述第一SSB子周期的时域位置在所述第二SSB子周期的时域位置之前,所述方法还包括:
响应于M和N均等于64,并且在所述第二SSB子周期的所述半帧的第一类候选位置接收到的所述SSB的索引号大于或等于32,确定接入网设备发送的SSB数量大于32。
第一SSB子周期可以用于发送索引为0至31的SSB,第二SSB子周期可以用于发送索引为32至63的SSB。
当UE在第二SSB子周期的半帧的第二类候选位置接收到的所述SSB的索引号大于或等于31,则可以确定第一SSB子周期和第二SSB子周期发送的SSB数量大于32个。
以下结合上述任意实施例提供一个具体示例:
1、120kHz SCS配置下,基站配置最大64个SSB。同时,定义SSB子周期的概念。即两个SSB子周期等于一个实际的SSB周期
2、基站配置SSB的周期,对于初始接入默认的20ms周期,那么SSB子周期就是10m
3、在第一个10ms内的5ms SSB发送窗口里,SSB实际发送的位置是前32个第一类候选位置,占用前2.5ms;后面2.5ms是第二类候选位置。
4、同理,第二个10ms的子周期里的前2.5ms是实际发送的第一类候选位置,后面是第二类候选位置。
5、对于UE,对120kSCS SSB默认用SSB子周期来搜索,当在第1子周期的后2.5ms搜索到SSB index小于32,则确定基站发送的总SSB数/或者说最大beam数大于32;同理,在第二子周期的前2.5ms搜索到SSB index大于31,则确定基站发送的总SSB数/或者说最大beam数大于32。
6、基于上述方法,如果基站配置的SSB数量小于32,则SSB子周期概念自动消失,仍然在一个SSB周期中的一个半帧发送SSB。
