Description

一种系统信息块调度方法及装置 技术领域
本申请涉及无线通信技术领域,特别涉及一种系统信息块调度方法及装置。
背景技术
第五代(the fifth-generation,5G)移动通信技术,新无线(new radio,NR)系统,是下一代非常重要的蜂窝移动技术,其面向包括大规模机器通信(massive machine-type communication,mMTC)业务在内的多种业务。NR系统中,基站需要向终端设备发送到小区的系统信息(system information,SI),以便终端设备接入该小区并在该小区内正常地工作。系统信息主要包括主信息块(master information block,MIB)和系统信息块(system information block,SIB)。其中,定义了14种类型的SIB:从SIB类型(type)1到SIB类型14,分别简称为SIB1,SIB2,…,SIB14。除SIB1之外的SIB也称其他系统信息(other system information,OSI)。
NR系统中,SIB1是通过物理下行控制信道(physical downlink control channel,PDCCH)进行调度的,SIB1频域资源调度范围为24资源块(resource block,RB)或者48RB或者96RB。而随着在NR系统中引入低成本窄带物联终端设备,此时调度SIB1的PDCCH能够占用的带宽也相应缩减,因此如果维持和NR系统中相同的性能的SIB1,PDCCH的时域符号开销会增大。
为此本申请提供一种调度SIB1的方法,尽量降低调度SIB1的开销的同时,还能够满足网络调度SIB1的灵活性的需求。

通过实施该方法,通过物理广播信道承载的信息携带第一系统信息块1的调度信息,避免了按照传统方法中采用PDCCH调用第一系统信息块1时,PDCCH开销过大的影响。此外可以减少通过物理广播信道承载的主信息块直接调度第一系统信息块1的开销,并可以尽量提升调度第一系统信息块1的灵活度。

具体实施方式
下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、新无线(New Radio,NR)等,在此不做限制。
本申请实施例中,终端设备,可以为具有无线收发功能的设备或可设置于任一设备中的芯片,也可以称为用户设备(user equipment,UE)、接入终端、用户单元、移动站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端等。
网络设备,可以是NR系统中的下一代基站(next Generation node B,gNB),可以是LTE系统中的演进型基站(evolutional node B,eNB),可以是全球移动通讯(global system of mobile communication,GSM)系统或码分多址(code division multiple access,CDMA)中的基站(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)系统中的基站(nodeB,NB)等。
图1是本申请一个实施例的通信系统100的示例性架构图。本申请实施例中的方法可以应用于图1所示的通信系统100中。应理解,可以应用本申请实施例的方法的通信系统100中可以包括更多或更少的网络设备或终端设备。
图1中的网络设备或终端设备可以是硬件,也可以是从功能上划分的软件或者以上二者的结合。图1中的网络设备或终端设备之间可以通过其他设备或网元通信。
图1所示的通信系统100中,网络设备110和终端设备101~终端设备106组成一个通信系统100。在该通信系统100中,网络设备110可以向终端设备101~终端设备106发送下行数据,当然,终端设备101~终端设备106也可以发送上行数据给网络设备110。通信系统100可以是LTE网络或NR网络、设备到设备(device-to-device,D2D)网络、机器到机器(machine to machine,M2M)网络等。
本申请中,网络设备支持多波束(beam)工作模式,网络设备在每个波束中均发送SIB1,不同波束中发送的SIB1需要不同的调度信息进行调度。如果通过MIB调度SIB1,那么在每个波束中发送的MIB,需要包括所有波束对应的SIB1的调度信息,这样可以灵活的向终端设备指示每个波束对应的SIB1。但是这样会导致MIB的开销变大,降低系统效率。本申请提供一种方法,可以解决上述问题,下面将详细描述。
需要说明的是,本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请实施例中,以终端设备和接入网设备等设备之间的交互为例进行说明,本申请实施例提供的方法还可以适用于其他执行主体之间的交互,例如可以是终端设备芯片或模块,与接入网设备中的芯片或模块之间的交互,当执行主体为芯片或模块时,可以参考本申请实施例中的描述,在此不再赘述。
结合前面的描述,如图2所示,为本申请实施例提供的一种系统信息块调度方法流程示意图。参见图2,该方法包括:
步骤201:网络设备生成第一信息和第二信息。
其中,第一信息指示多个系统信息块1对应的各自的调度信息中的公共信息;第二信息指示第一系统信息块1的调度信息中除了第一信息之外的信息,第一系统信息块1为多个系统信息块1中的一个系统信息块1。
第一信息也可以称为公共(common)信息,第二信息也可以称为私有(specific)信息,本申请对第一信息和第二信息的具体名称并不限定。
需要说明的是,当网络设备支持多波束工作模式时,每个波束配置一个同步信号块(synchronization signal block,SSB),每个SSB包括的PBCH承载的信息可以调度一个系统信息块1,该多个系统信息块1可以是指在多个波束对应的多个系统信息块1。当然,以上只是示例,多个系统信息块1并不限定于多波束工作模式中。
第一信息指示的公共信息,可以是多个系统信息块1对应的各自的调度信息中相同的信息。例如,多个系统信息块1占用相同的频域资源,那么该频域资源的位置可以属于公共信息。
步骤202:网络设备向终端设备发送第一信息和第二信息。
本申请实施例中,网络设备可以通过物理广播信道(physical broadcast channel,PBCH)发送第一信息和第二信息。具体的,PBCH中承载MIB(承载高层RRC信令信息)和L1信息(物理层额外添加的信息),第一信息可以位于PBCH承载的MIB中,第二信息位于PBCH承载的L1信息中。
需要说明的是,网络设备发送的同步信号块(synchronization signal block,SSB)中包括PBCH中承载的信息。本申请实施例中,PBCH承载的信息携带第一系统信息块1的调 度信息,该调度信息包括两个部分,分别为第一信息和第二信息。
假设网络设备支持多波束工作模式,每个波束需要发送一个系统信息块1,即每个波束对应一个系统信息块1,为此,网络设备可以通过第一系统信息块1对应的波束发送第一信息和第二信息。
步骤203:终端设备接收来自网络设备的第一信息和第二信息。
步骤204:终端设备根据第一信息以及第二信息接收第一系统信息块1。
通过本申请提供的方法,通过PBCH承载信息中携带SIB1的调度信息,避免了按照传统NR系统利用PDCCH调用SIB1时,窄带情况下,PDCCH开销过大的影响。此外本申请可以减少PBCH承载的MIB直接调度SIB1的开销,并可以尽量提升了网络设备调度SIB1的灵活度。
本申请实施例对第一信息指示的内容和第二信息指示的内容并不限定,只要是属于多个调度信息的公共信息(或相同信息),都可以通过第一信息指示。其中多个调度信息为多个系统信息块1对应的各自的调度信息,举例来说,第一信息可以指示以下一项或多项:
多个系统信息块1共同占用的频域资源的位置;
多个系统信息块1的重复次数;
多个系统信息块1的编码调制策略(modulation and coding scheme,MCS);
多个系统信息块1的冗余版本(redundancy version,RV)。
需要说明的是,如果第一信息不包括其中的任一信息,则该信息可以为默认值。例如第一信息不包括频域资源的位置时,则频域资源的位置可以为默认的位置。再例如第一信息不包括重复次数时,则重复次数可以为默认的重复次数。
相应的,只要是第一系统信息块1对应的调度信息中,与多个系统信息块1中其他系统信息块1对应的调度信息不同的信息,都可以通过第二信息指示,例如第二信息可以指示第一系统信息块1占用的时域资源的位置,该时域资源的位置,可以是第一系统信息块1在一次重复周期中的时隙位置。重复周期可以为20ms,也可以为其他值,具体可以参考现有技术中的描述。
本申请中,不再通过PDCCH调度SIB1,直接通过MIB调度SIB1。通过这种方式,MIB中原来用于调度PDCCH的信息可以进行缩减;然后通过MIB携带调度SIB1的第一信息,通过L1携带调度SIB1的第二信息。
举例来说,现有技术中的MIB包括以下内容:
Figure PCTCN2020119160-appb-000001
通过上面的描述可知,MIB中包括pdcch-ConfigSIB1和dmrs-TypeA-Position等参数,参数pdcch-ConfigSIB1,指示SIB1所在的控制资源集合(control resource set,CORESET)的时频域位置和周期,该参数包括8比特(bit)。参数dmrs-TypeA-Position包括1个比特,指示解调参考信号(demodulation reference signal,DMRS)的第一个符号位置。MIB中的其他参数可以参考第三代伙伴计划(the 3rd generation partnership project,3GPP)技术规范(technical specification,TS)38.331版本(version,V)15.8.0第6.2.2章节等文献中的描述,在此不再赘述。
可选地,MIB中不再包括参数pdcch-ConfigSIB1,本申请中,可以通过参数pdcch-ConfigSIB1对应的8个比特承载(或者携带)第一信息。具体的,一种可能实现方式中,第一信息可以指示出频域资源的位置、编码调制策略以及冗余版本,重复次数为默认值,在该情况下,频域资源的位置可以通过前面描述的8个比特中的4个比特指示,编码调制策略可以通过描述的8个比特中的3个比特指示,冗余版本可以通过描述的8个比特中的1个比特指示。
在该实现方式中,MIB可以包括以下内容:
Figure PCTCN2020119160-appb-000002
其中,SIB1 Frequency domain,指示第一系统信息块1的频域资源的位置;SIB1 MCS指示第一系统信息块1的MCS;SIB1 RV指示第一系统信息块1的RV。需要说明的是,上面的MIB中的其他参数可以参考3GPP TS 38.331 V15.8.0第6.2.2章节等文献中的描述,在此不再赘述。
另一种可能实现方式中,第一信息可以指示出频域资源的位置以及编码调制策略,冗余版本和重复次数为默认值,在该情况下,频域资源的位置可以通过描述的8个比特中的5个比特指示,编码调制策略可以通过描述的8个比特中的3个比特指示。
在该实现方式中,MIB可以包括以下内容:
Figure PCTCN2020119160-appb-000003
Figure PCTCN2020119160-appb-000004
其中,SIB1 Frequency domain,指示第一系统信息块1的频域资源的位置;SIB1 MCS指示第一系统信息块1的MCS。需要说明的是,上面的MIB中的其他参数可以3GPP TS 38.331 V15.8.0第6.2.2章节等文献中的描述,在此不再赘述。
当然以上只是示例,通过MIB携带第一信息时,还可能存在其他实现方式,在此不再逐一举例说明。
可选地,L1信息包括8个比特,分别为
Figure PCTCN2020119160-appb-000005
Figure PCTCN2020119160-appb-000006
其中的保留比特为
Figure PCTCN2020119160-appb-000007
Figure PCTCN2020119160-appb-000008
本申请中,可以通过L1信息中的3个比特携带第二信息,例如可以通过保留比特
Figure PCTCN2020119160-appb-000009
Figure PCTCN2020119160-appb-000010
以及
Figure PCTCN2020119160-appb-000011
指示第一系统信息块1占用的时域资源的位置。
需要说明的是,本申请实施例中,当网络设备支持多波束工作模式时,网络设备可以发送多个不同方向的波束,每个波束配置一个SSB,为此,网络设备在每个波束中都发送一个SSB,该SSB包括的PBCH承载的信息,包括调度该SSB对应的波束的SIB1的调度信息,该调度信息包括第一信息和第二信息。举例来说,如图3所示,图3中以4个波束为例进行描述。波束0至波束3中,分别发送第一SSB至第四SSB;第一SSB至第四SSB包括的PBCH承载的信息,分别调度了第一SIB1至第四SIB1。
进一步的,如果第一系统信息块1占用的时域资源的位置对应M个比特位,那么第一信息还可以包括第三信息,第三信息包括所述M个比特位中的至少一个高比特位(high bit),所述第二信息包括所述M个比特位中除了所述至少一个高比特位之外的比特位。其中M为大于1的整数。至少一个高比特位可以是指M个比特位中,从左往右顺序,最前面的至少一个比特位。高位比特还可以称为最高有效比特位(most significant bit,MSB)。
通过这种方式,所述第三信息和所述第二信息可以联合指示出所述第一系统信息块1占用的时域资源的位置,进一步降低主信息块中的开销。
举例来说,M等于4,第1个SIB1在时隙(slot)2中传输,第2个SIB1在时隙3中传输,第3个SIB1在时隙4中传输,第3个SIB1在时隙5中传输,对应的M个比特位的取值可以如表1所示。
表1
  时隙2 时隙3 时隙4 时隙5
M个比特位的取值 0010 0011 0100 0101
通过表1可知,所有时隙对应的最高比特位相同,均为0,那么可以将0作为第三信息,通过MIB携带;每个时隙对应的后3个比特,可以通过在各自时隙中发送的L1信息携带。
举例来说,结合前面的描述,本申请中,MIB中不再包括参数pdcch-ConfigSIB1,该参数包括的8个比特,可以携带第一信息。具体的,一种可能实现方式中,第一信息可以指示出频域资源的位置以及编码调制策略,第一信息还包括第三信息,冗余版本和重复次 数为默认值,在该情况下,频域资源的位置可以通过描述的8个比特中的4个比特指示,编码调制策略可以通过描述的8个比特中的3个比特指示,第三信息可以通过描述的8个比特中的1个比特携带。
例如MIB可以如下所示:
Figure PCTCN2020119160-appb-000012
其中,SIB1 Frequency domain,指示第一系统信息块1的频域资源的位置;SIB1 MCS指示第一系统信息块1的MCS;假设第一系统信息块1的时域资源的位置对应4个比特位,SIB1 Time domain MSB为第三信息,可以指示第一系统信息块1的时域资源的位置对应4个比特位中的1个高比特位。需要说明的是,上面的MIB中的其他参数可以参考3GPP TS 38.331 V15.8.0第6.2.2章节等文献中的描述,在此不再赘述。
在该实现方式中,L1信息中的第二信息,包括第一系统信息块1的时域资源的位置对应4个比特位中的剩余3个比特位。例如,可以通过L1信息中的保留比特

Figure PCTCN2020119160-appb-000014
以及
Figure PCTCN2020119160-appb-000015
指示第一系统信息块1占用的时域资源的位置对应4个比特位中的剩余3个比特位。
另一种可能实现方式中,MIB中不再包括参数pdcch-ConfigSIB1和参数dmrs-TypeA-Position。在该实现方式中,参数pdcch-ConfigSIB1和参数dmrs-TypeA-Position对应9个比特,可以通过MIB中的这9个比特携带第一信息。第一信息可以指示出频域资源的位置以及编码调制策略,冗余版本和重复次数为默认值,在该情况下,频域资源的位置可以通过前面描述的9个比特中的4个比特指示,编码调制策略可以通过前面描述的9个比特中的3个比特指示,第三信息可以通过描述的9个比特中的2个比特携带。
例如MIB可以如下所示:
Figure PCTCN2020119160-appb-000016
Figure PCTCN2020119160-appb-000017
其中,SIB1 Frequency domain,指示第一系统信息块1的频域资源的位置;SIB1 MCS指示第一系统信息块1的MCS;假设第一系统信息块1的时域资源的位置对应5个比特位,SIB1 Time domain MSB为第三信息,可以指示第一系统信息块1的时域资源的位置对应5个比特位中的2个高比特位。需要说明的是,上面的MIB中的其他参数可以参考3GPP TS 38.331 V15.8.0第6.2.2章节等文献中的描述,在此不再赘述。
在该实现方式中,在该实现方式中,L1信息中的第二信息,包括第一系统信息块1的时域资源的位置对应5个比特位中的剩余3个比特位。例如,可以通过L1信息中的保留比特
Figure PCTCN2020119160-appb-000018
Figure PCTCN2020119160-appb-000019
以及
Figure PCTCN2020119160-appb-000020
指示第一系统信息块1占用的时域资源的位置对应5个比特位中的剩余3个比特位。
在该实现方式中,举例来说,第1个SIB1在时隙2中传输,第2个SIB1在时隙3中传输,第3个SIB1在时隙4中传输,第3个SIB1在时隙5中传输,对应的M个比特位的取值可以如表1所示。第一系统信息块1的时域资源的位置对应的5个比特位的取值可以如表2所示。
表2
  时隙2 时隙3 时隙4 时隙5
5个比特位的取值 00010 00011 00100 00101
表2中,从左至右,最前面的2个比特的取值为00,可以通过MIB中的第三信息(SIB1 Time domain MSB)携带,剩余的3个比特的取值可以通过每个SIB1对应的L1信息携带。
当然以上只是示例,通过MIB携带第一信息时,还可能存在其他实现方式,在此不再逐一举例说明。
需要说明的是,本申请并不限定于上面的实施方式,另一种可能的实现方式中,假设网络设备需要发送N个波束,N为大于0的整数。网络设备可以确定第一信息和N个第二信息,第一信息指示N个系统信息块1对应的各自的调度信息中公共信息;N个第二信息中的一个第二信息指示N个系统信息块1中的一个系统信息块1的调度信息中除了第一信息之外的信息。
N个系统信息块1中每个系统信息块1对应一个波束,假设第一系统信息块1对应第一波束,网络设备可以在第一波束中向终端设备发送所述第一信息和所述N个第二信息;其中所述第一信息位于物理广播信道承载的主信息块中,第一系统信息块1对应的第二信息位于物理广播信道承载的L1信息中,N个第二信息中除了第一系统信息块1对应的第二信息,位于主信息块中。
