Therefore, when the enhanced DRS includes two subframes in the time domain, and the remaining frequency domain resources other than the middle 6 RBs are used to carry the payload of the MF system information block, the channel quality is required to ensure that the terminal normally demodulates the MF system information. Piece. When the channel quality is poor, for example, when the signal-to-noise ratio is below -10 dB, it is difficult for the terminal to normally demodulate the MF system information block.
- the channel quality of the terminal is usually fluctuating.
- the channel quality fluctuation can be understood as: at a certain moment, the channel quality of the terminal is good, and at another moment, the channel quality of the terminal is poor. Therefore, when the terminal is in poor channel quality, the received DRS may not correctly demodulate the MF system information block, and if the terminal receives the DRS at a time when the channel quality is good, the MF system may be detected and demodulated.
- the terminal in the case that the terminal determines that the MF system information block is not correctly demodulated, the terminal may perform detection and demodulation of the MF system information block at other times, and perform the MF system information block multiple times. Detection and demodulation can increase the chances of detection and demodulation of the terminal in the case of better channel quality, and thus improve the probability that the terminal successfully demodulates the information block of the MF system.

It is to be understood that the following embodiments of the present application are described by using the enhanced DRS as an example. However, the following method for scheduling the MF system information block is also applicable to the existing DRS, and the specific implementation manner is similar. .

So that the terminal can determine the transmission time of the enhanced DRS, and then detect the MF system information block at the corresponding subframe position at the transmission time of the enhanced DRS, and demodulate each detected MF system information block to increase the channel quality. In a good case, the opportunity to demodulate the information block of the MF system is improved, and the probability of successfully demodulating the information block of the MF system is improved.
- the DMTC period information may be included in the MIB-MF, so that the terminal can determine the DMTC period by using the MIB-MF including the DMTC period information after receiving the MIB-MF that is sent by the network device, including the DMTC period information, for example, The terminal obtains the DMTC period by demodulating the MIB-MF including the DMTC period information.

Description
本申请涉及通信技术领域,尤其涉及一种调度系统信息块的方法及装置。
随着通信业务低成本、低功耗、易部署和免维护的需求,部署在免授权频谱上的MF(MulteFire)通信系统应用越来越广泛。
MF通信系统中,终端(例如用户设备(User Equipment,UE))通过接收网络设备(例如基站)的发现信号(discovery signal,DRS)来完成接入网络的通信流程。MF通信系统中的DRS包括用于终端获取下行同步和物理小区标识(physical cell ID,PCI)的同步信号、用于终端获取MF主信息块(Master Information Block-MF,MIB-MF)以及用于终端获取系统信息的MF系统信息块(System Information Block-MF1,SIB-MF1)。其中,同步信号主要包括主同步信号(primary synchronization signal,PSS),MF主同步信号(MF-primary synchronization signal,MF-PSS),辅同步信号(secondary synchronization signal,SSS),MF辅同步信号(MF-secondary synchronization signal,MF-SSS)。MIB-MF主要包括系统带宽、帧号和子帧偏移等信息,承载在MF物理广播信道(physical broadcast channel,MF-PBCH)中。MF系统信息块中主要包括发现信号测量定时(Discovery Signal Measurement Timing,DMTC)的配置参数,诸如指示DMTC周期的DMTC周期信息(dmtc-Periodicity-mf),指示DMTC窗口长度的DMTC窗口长度信息(dmtc-WindowSize-mf),以及指示在DMTC周期内的DMTC窗口的子帧起始位置的DMTC偏移信息(dmtc-Offset-mf)。
通常,网络设备只能通过一个子帧向多个终端发送DRS,该DRS包括在一个子帧内传输,占用12个或14个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号,其中,PSS、SSS、MF-PSS以及MF-SSS分别占用1个符号。另外,MF-PBCH占用6个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号。终端接收到DRS后解析PSS、MF-PSS,SSS,MF-SSS,以便得到物理小区标识,解析MF-PBCH以便获得系统带宽等信息,并完成与网络设备的时钟和频率同步,进而获取MF系统信息块并解调该MF系统信息块,得到系统信息。
然而,MF通信系统中经常会出现终端处于信号质量较差的弱覆盖场景,例如当MF通信系统部署于港口、码头、自动化生产流等场景时,由于终端普遍具有较高的移动性,在终端的移动过程中,网络设备发送的无线信号容易被终端和网络设备之间各种物体遮挡,从而导致无线信号质量较差,终端可能无法正常接收。再例如,由于终端数量较大,在移动过程中,容易发生互相遮挡无线信号的情况,也会导致终端可能无法正常接收网络设备发送的数据。再有,MF通信系统是部署在免授权频谱上的通信系统,存在着与其他通信系统共存的场景,比如图1中MF通信系统与无线保真(Wireless Fidelity,WiFi)共存的场景中,在WiFi接入点(WiFi Access Point,WiFi AP)较多,通信需求较大时,MF通信系统中的演进基站(eNB)与WiFi系统中的WiFi AP之间干扰比较严重,终端与eNB之间正常收发无线数据过程会受限。
在现有MF通信系统中,当终端处于上述信号质量较差的弱覆盖场景时,若DRS在一个子帧内完成传输,则会出现终端不能正常接收DRS的情况,使得终端无法获得MF系统信息块,进而不能获得系统信息,无法接入网络。
发明内容

下面将结合附图,对本申请实施例进行描述。
首先,对本申请中的部分用语进行解释说明,以便于本领域技术人员理解。
1)、网络设备,可以称之为无线接入网(Radio Access Network,RAN)设备,是一种将终端接入到无线网络的设备,包括但不限于:演进型节点B(evolved Node B,eNB)、无线网络控制器(Radio Network Controller,RNC)、节点B(Node B,NB)、基站控制器(Base Station Controller,BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如,Home evolved NodeB,或Home Node B,HNB)、基带单元(BaseBand Unit,BBU)、无线保真(Wireless Fidelity,WIFI)接入点(Access Point,AP),传输点(transmission and receiver point,TRP或者transmission point,TP)等。
2)、终端,是一种向用户提供语音和/或数据连通性的设备,可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile station,MS),终端设备(Terminal Equipment),传输点(transmission and receiver point,TRP或者transmission point,TP)等等。
3)、交互,本申请中的交互是指交互双方彼此向对方传递信息的过程,这里传递的信息可以相同,也可以不同。例如,交互双方为基站1和基站2,可以是基站1向基站2请求信息,基站2向基站1提供基站1请求的信息。当然,也可以基站1和基站2彼此向对方请求信息,这里请求的信息可以相同,也可以不同。
4)、“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
5)、主信息块、MIB、MF主信息块和MIB-MF为同一概念,在不强调其区别时,其所要表达的含义是一致的。系统信息块、SIB-MF1和MF系统信息块也为同一概念,在不强调其区别时,其所要表达的含义也是一致的。
名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。信息(information),信号(signal),消息(message),信道(channel)有时可以混用,应当指出的是,在不强调其区别时,其所要表达的含义是一致的。“的(of)”,“相应的(corresponding,relevant)”和“对应的(corresponding)”有时可以混用,应当指出的是,在不强调其区别时,其所要表达的含义是一致的。
本申请实施例提供的调度MF系统信息块的方法,可应用于MF通信系统。其中,MF是一种部署在免授权频频谱上的无线通信系统,适应于企业、工厂、车间、仓库等独立部署的智能化作业场景,然而在这些作业场景中,由于终端的移动性,使得终端移动过程中,网络设备发送的无线信号容易被终端和网络设备之间各种物体遮挡,例如图2所示,此种情况下信号衰落严重,从而导致无线信号质量较差,使终端可能无法正常接收网络设备发送的下行信号,例如终端无法正常接收DRS信号,进而使得终端无法接入网络。
本申请实施例中面对上述问题,可对MF系统的下行覆盖进行增强,例如对DRS和MF系统信息块的增强,以使终端正常接入网络。本申请实施例以下主要以MF通信系统的DRS信号进行举例说明。
本申请实施例中首先对MF通信系统中发送的DRS的格式进行说明。MF通信系统中的
DRS格式如图3所示。图3中,MF通信系统中的DRS包括长期演进(Long Term Evolution,LTE)中已有的PSS/SSS,还包括MF-PSS/MF-SSS、MF-PBCH和MF系统信息块等。其中,MF-PSS/MF-SSS分别占用1个符号,MF-PBCH占用6个符号。MF通信系统中的DRS中的同步信号和PBCH占用中间6个物理资源块(Physical Resource Block,PRB),在剩余的PRB内,网络设备用物理下行控制信道(Physical Downlink Control Channel,PDCCH)携带调度信息,调度MF系统信息块,并用物理下行链路共享信道(Physical Downlink Shared Channel,PDSCH)承载MF系统信息块的内容。
本申请实施例中以下对MF通信系统中发送DRS的时机进行说明。MF通信系统中,网络设备通过dmtc-Periodicity-mf,dmtc-Offset-mf和dmtc-WindowSize-mf等DMTC配置参数,确定发送DRS的时机。例如,可采用如下方式确定发送DRS的时机:
SFN mod T=FLOOR(dmtc-Offset/10);
subframe=dmtc-Offset mod 10;
with T=dmtc-Periodicity/10。
上述确定发送DRS时机的指令中,SFN(system frame Number)表示系统帧号,subframe表示子帧号,T表示以无线帧(radio frame)为单位的DMTC发送周期,mod表示取余运算,FLOOR表示向下取整。通常主小区(serving cell)配置中,dmtc-Offset默认为0。例如,如果dmtc-Periodicity-mf配置为40ms,dmtc-Offset-mf配置为0,dmtc-WindowSize-mf配置为10ms,则DMTC开始的位置为子帧0,周期为40ms,DMTC Window长度为10ms(即子帧0~子帧9),DRS发送时机如图4所示。
在MF通信系统中,网络设备发送数据之前可以利用两个类别的先检测后发送(Listen-Before-Talk,LBT)对信号进行侦听。例如,基于随机回退的信道空闲评估以及非基于随机回退的信道空闲评估,具体可以以Cat.4 LBT和Cat.2 LBT为例进行说明。Cat.2LBT,指非基于随机回退的信道空闲评估(Clear Channel Assessment,CCA),例如可以是在发送节点对信道进行侦听,如果在25us内检测信道空闲,则发送节点可以立即占用该信道进行数据发送。Cat.4 LBT,为基于随机回退的CCA,需要的侦听时长是需要随机化的,具体可以为:发送节点在0至竞争窗长度(Contention Window Size,CWS)之间均匀随机生成一个回退计数器N,并且以侦听时隙(CCA slot)为粒度进行侦听,如果侦听时隙内检测到信道空闲,则将回退计数器减一,反之检测到信道忙碌,则将回退计数器挂起,即回退计数器N在信道忙碌时间内保持不变,直到检测到信道空闲;当回退计数器减为0时发送节点可以立即占用该信道。
采用上述配置,网络设备可在DMTC window(即子帧0~子帧9)内,从子帧0开始前25us执行Cat.2 LBT进行信道侦听,如果侦听到信道在25us内一直处于空闲状态,则网络设备发送DRS。如果Cat.2 LBT失败,也即侦听到信道在25us内非一直处于空闲状态,则网络设备可以在下一个子帧前25us继续执行Cat.2 LBT侦听信道。网络设备如果针对某个子帧Cat.2 LBT成功之后发送了DRS,则在剩余的DMTC window内,不再发送DRS。
本申请实施例中为实现DRS增强,扩大MF通信系统中下行信号的覆盖范围,使得无线信号质量较差时,终端也能够正确接收DRS(例如正确接收MF系统信息块),可在时域上对DRS进行多子帧扩展。然而,若DRS在时域上的子帧长度超过一个子帧长度,网络设备需要执行Cat.4 LBT对信道进行侦听,本申请实施例中为了保证DRS有更多的发送机会,增强的DRS在时域上的子帧长度最好不超过2个子帧,使得网络设备可以执行priority 1 Cat.4
LBT对信道进行侦听,需要信道空闲的时间较短,从而能够更快地获得传输机会,保证增强DRS的及时发送。
本申请实施例中以增强DRS在时域上包含子帧n和子帧n+1两个子帧为例进行说明。
图5为本申请实施例提供的增强DRS的格式的一种示意图。参阅图5所示,子帧n的中间6个资源块(Resource Block,RB)的前12个符号为已有的PDCCH、同步信号和PBCH,最后两个符号为新增加的PSS,本申请实施例中将新增加的PSS称为MF-ePSS。子帧n+1的前两个符号为新增加的SSS,本申请实施例中将新增加的SSS的称为MF-eSSS。MF-eSSS与MF-SSS/SSS相同,终端进行辅同步序列检测时,可以与MF-SSS/SSS进行合并。子帧n+1的后12个符号为新增加的PBCH,本申请实施例中将新增加的PBCH称为MF-ePBCH。MF-ePBCH占连续6个符号,也可以理解为子帧n+1中包含两个MF-ePBCH。
其中,MF-ePSS可为ZC序列,其根指数与PSS和MF-PSS不同,可以按照下表1进行选择:
NID (2) | 根指数 | MF-PSS根指数 | MF-ePSS根指数 |
0 | 25 | 40 | 5 |
1 | 29 | 44 | 10 |
2 | 34 | 59 | 15 |
表1
其中,NID
(2)表示在一个PCI组内的所对应的PCI。PCI取值范围为0~503,并分为168个PCI组,每个PCI组内包含3个PCI。也即,在一个PCI组内包含的3个PCI分别对应NID
(2)取值为0,1,和2
进一步的,为了降低MF-ePSS之间的互相关性,两个MF-ePSS符号可用正交掩码[-1,1]或者[1,-1]在时域上加掩。
图6所示为本申请实施例提供的增强DRS的格式的另一种示意图。图6所示的增强DRS格式与图5所示的增强DRS格式类似,不同之处在于,子帧n+1的符号2、符号3上为MF-eSSS,符号0、符号1、符号4、符号5、符号6和符号7上为包含6个符号的MF-ePBCH。采用图6所示的增强DRS格式可以避开符号0、符号1上的小区专属导频信号(Cell-specific reference signals,CRS)。
图7所示为本申请实施例提供的增强DRS格式的又一种示意图。图7所示的增强DRS格式与图5所示的增强DRS格式类似,不同之处在于,MF-ePSS和MF-eSSS互换位置。
图8所示为本申请实施例提供的增强DRS格式的又一种示意图。图8所示的增强DRS格式与图6所示的增强DRS格式类似,不同之处在于,MF-ePSS和MF-eSSS互换位置。
图9所示为本申请实施例提供的增强DRS格式的又一种示意图。参阅图9所示,子帧n中间6个RB的前12个符号为已有的PDCCH、同步信号和MF-PBCH,最后两个符号为MF-eSSS。MF-eSSS由基序列和扰码构成,基序列为MF-SSS/SSS,扰码共有5种,每种扰码与子帧偏移(sf-offset)一一对应。扰码的长度与基序列相同。网络设备根据DRS的起始子帧号来确定sf-offset,进而选择对应的扰码。对基序列进行加扰后生成MF-eSSS,两个符号的MF-eSSS相同。子帧n+1中的前两个符号为PDCCH,后续两个符号为MF-ePSS,最后10个符号为MF-ePBCH,所包含的内容,也即MIB-MF,与子帧n的MF-PBCH相同。
图10所示为本申请实施例提供的增强DRS格式的又一种示意图。参阅图10所示,子帧n
中的符号2到符号5为MF-ePSS,符号6到符号9为MF-eSSS,符号10到符号13为MF-ePBCH。子帧n+1中符号2到符号7为MF-ePBCH,最后6个符号同样为MF-ePBCH。MF-eSSS可以用扰码加扰指示子帧偏移,也可以不用。
需要说明的是,图10所示的增强DRS格式中,子帧n中MF-ePSS、MF-eSSS和MF-ePBCH所占符号数、符号位置可以与图10所示位置不同,只要位于子帧n即可。
本申请实施例中采用上述涉及的增强DRS格式进行DRS发送时,增强DRS在时域上包含两个子帧,相比现有DRS,同步信号所占资源扩展了一倍,物理广播信道资源扩展了约3倍。因此,当终端接收到增强DRS时,能够利用更多的资源对同步信号和物理广播信道进行检测和解调,即使在无线信道质量较差的场景,也可对同步信号和物理广播信道进行正确接收。网络设备可以利用除中间6个RB之外的频域资源承载MF系统信息块,例如,本申请实施例中MF系统信息块的调度信息可利用PDCCH/ePDCCH承载,信息比特利用PDSCH承载。
本申请实施例中,MF系统信息块中包含SIB1和SIB2的必要信息,总比特数在1000比特以上,需要较多的资源承载才能保证较好的覆盖范围。因此,当增强DRS在时域上包含两个子帧,利用除中间6个RB之外的剩余频域资源承载MF系统信息块的载荷时,需要信道质量较高才能保证终端正常解调MF系统信息块。当信道质量较差,比如信噪比在-10dB以下时,终端很难正常解调MF系统信息块。
在一般情况下,终端的信道质量通常是波动的,所述信道质量波动可以理解为:在某一时刻,终端的信道质量较好,而在另外一时刻,终端的信道质量较差。因此,当终端在信道质量较差时,接收到的DRS可能无法正确解调出MF系统信息块,而如果终端在信道质量较好的时刻接收到DRS,则可以检测到并解调出MF系统信息块,故本申请实施例中,终端在确定未正确解调得到MF系统信息块的情况下,可在其它时刻再进行MF系统信息块的检测与解调,多次进行MF系统信息块的检测与解调,可增加终端在信道质量较好的情况下检测与解调的机会,进而可提高终端成功解调得到MF系统信息块的几率。
本申请实施例以下以DRS为增强DRS为例,对本申请实施例提供的调度MF系统信息块的方法进行说明。可以理解的是,本申请以下实施例虽然是以增强DRS为例进行说明的,但是以下涉及的调度MF系统信息块的方法也适用于现有DRS,具体执行方式类似,本申请不再详述。
本申请实施例中,为进一步的提高终端解调MF系统信息块的成功率,在调度MF系统信息块时,可由网络设备在终端接收MF系统信息块之前,向终端发送增强DRS的DMTC周期信息,以使终端能够确定增强DRS的发送时刻,进而在增强DRS的发送时刻对应子帧位置处检测MF系统信息块,并对每次检测到的MF系统信息块解调,以增加在信道质量较好的情况下解调MF系统信息块的机会,提高成功解调MF系统信息块的几率。
本申请实施例中采用上述涉及的增强DRS格式进行DRS发送时,终端正常检测与成功解调MIB-MF的几率相对检测并成功解调MF系统信息块的几率而言,会比较高,故本申请实施例中可在MIB-MF中包括DMTC周期信息,以使终端接收到网络设备发送的包括DMTC周期信息的MIB-MF后可通过该包括DMTC周期信息的MIB-MF,确定DMTC周期,例如,终端通过解调该包括DMTC周期信息的MIB-MF,得到DMTC周期。终端在位置位于所述DMTC周期内的子帧上,检测网络设备发送的MF系统信息块,使终端能够确定增强DRS的发送时刻,进而在增强DRS的发送时刻对应子帧位置处检测MF系统
信息块,并对每次检测到的MF系统信息块解调,以增加在信道质量较好的情况下解调MF系统信息块的机会,提高成功解调MF系统信息块的几率。
图11所示为本申请实施例提供的调度MF系统信息块的实施方法流程图,参阅图11所示,包括:
S101:网络设备向终端发送MIB-MF,终端接收网络设备发送的MIB-MF,所述MIB-MF中包括DMTC周期信息。
其中,所述MIB-MF中包括的DMTC周期信息可以理解为是增强DRS的DMTC周期信息。
S102:网络设备向终端发送MF系统信息块,终端接收网络设备发送的MF系统信息块。
本申请实施例中MF系统信息块中包括有DMTC配置信息,该DMTC配置信息可以理解为是目前已有DRS的DMTC配置信息。
可以理解的是,若本申请实施例中提供的MF系统信息块的调度方法应用于现有DRS,则MIB-MF中包括的DMTC周期信息可以与MF系统信息块中包括的DMTC配置信息中的DMTC周期信息一致。
S103:终端通过该包括DMTC周期信息的MIB-MF,确定DMTC周期。
其中,终端可解调该包括DMTC周期信息的MIB-MF,得到DMTC周期。
S104:终端在位置位于得到的DMTC周期内的子帧上,检测网络设备发送的MF系统信息块。
目前的MIB-MF中除包括系统带宽、帧号和子帧偏移等信息的比特以外,还有剩余未使用的比特,故本申请实施例中可利用MIB-MF中剩余未使用的比特携带DMTC周期信息。
例如,本申请实施例中可占用MIB-MF的2比特承载DMTC周期信息,具体的信令配置可如下:
上述涉及的信令配置中,MasterInformationBlock-MF表示MIB-MF,dl-Bandwidth-mf表示传输带宽信息,systemFrameNumber-mf表示系统帧号前8bit信息(系统帧号一共10bit,其余2bit在MF-PBCH的扰码中携带),sf-Offset-mf表示子帧偏移信息,dmtc-Periodicity-mf表示DMTC周期信息,spare表示剩余比特。
本申请实施例中利用MIB-MF的2比特携带DMTC周期信息,在占用MIB-MF较少的比特携带DMTC周期信息的情况下,使终端在DMTC周期到达时,在位置位于所述DMTC周期内的子帧上,检测网络设备发送的MF系统信息块,例如DMTC周期为40ms则,终端可在满足SFN mod 4=0的无线帧开始,从子帧0到子帧9对应位置处检测增强DRS中的MF系
统信息块。
由于网络设备有可能并不是在DMTC整个周期内的每一子帧上发送增强DRS,而只是在DMTC窗口内发送增强DRS,故本申请实施例中MF系统信息块中还可包括DMTC窗口长度信息,终端解调包括DMTC窗口长度信息的所述主信息块,得到DMTC窗口长度,在位置位于所述DMTC周期内且位于DMTC窗口长度内的子帧上,检测网络设备发送的MF系统信息块,以避免终端在DMTC周期内未发送增强DRS的子帧上检测增强DRS中的MF系统信息块,一定程度上可降低终端检测子帧的功耗。
图12为本申请实施例提供的调度MF系统信息块的又一实施流程图,参阅图12所示,包括:
S201:网络设备向终端发送MIB-MF,终端接收网络设备发送的MIB-MF,所述MIB-MF中包括DMTC周期信息和DMTC窗口长度信息。
其中,所述MIB-MF中包括的DMTC周期信息和DMTC窗口长度信息可以理解为是增强DRS的DMTC周期信息和DMTC窗口长度信息。
S202:网络设备向终端发送MF系统信息块,终端接收网络设备发送的MF系统信息块。
本申请实施例中MF系统信息块中包括有DMTC配置信息,该DMTC配置信息可以理解为是目前已有DRS的DMTC配置信息。
可以理解的是,若本申请实施例中提供的MF系统信息块的调度方法应用于现有DRS,则MIB-MF中包括的DMTC周期信息和DMTC窗口长度信息,可以与MF系统信息块中包括的DMTC配置信息中的DMTC周期信息和DMTC窗口长度信息一致。
S203:终端通过该包括DMTC周期信息和DMTC窗口长度信息的MIB-MF,确定DMTC周期和DMTC窗口长度。
其中,终端可通过解调包括DMTC周期信息和DMTC窗口长度信息的MIB-MF,得到DMTC周期和DMTC窗口长度。
S204:终端在位置位于所述DMTC周期内、且位于DMTC窗口长度内的子帧上,检测网络设备发送的MF系统信息块。
本申请实施例中可利用MIB-MF中未使用的比特携带DMTC周期信息和DMTC窗口长度信息。其中,DMTC周期信息和DMTC窗口长度信息可联合编码也可独立编码。
例如,本申请实施例中可占用MIB-MF中的5比特对DMTC周期信息和DMTC窗口长度信息进行联合编码,具体的信令配置可如下:
其中,DMTC-mf表示DMTC周期信息和DMTC窗口长度信息的联合编码信息,共占用
5bit。
本申请实施例中,DMTC周期信息和DMTC窗口长度信息也可以分别编码。
例如,本申请实施例中可占用MIB-MF中的2比特对DMTC周期信息进行编码,利用MIB-MF中的4比特对DMTC窗口长度信息进行编码,具体的信令配置可如下:
其中,dmtc-Periodicity-mf表示DMTC周期信息,dmtc-WindowSizw-mf表示DMTC窗口长度信息。
DMTC周期信息和DMTC窗口长度信息的具体映射可采用如下表2所示的映射规则:
表2
本申请实施例中,DMTC配置信息中的DMTC周期和DMTC窗口长度可以设置不同的取值范围,比如,DMTC周期可配置的值可配置为80ms,160ms两种。DMTC时间窗的取值范围可以是如下情况:1~9ms,1~11ms,1~12ms,1~39ms和1~40ms中的一种或多种。
本申请实施例中,DMTC周期和DMTC窗口长度采用不同取值时,在MIB-MF中占用的比特数也不同。例如,DMTC周期为40ms,80ms,160ms三种取值,DMTC窗口长度为1~40ms时,采用对DMTC周期信息和DMTC窗口长度信息联合编码时需要7比特,MIB-MF具体的信令配置可如下:
例如,DMTC周期为40ms,80ms,160ms三种取值,DMTC窗口长度为1~40ms时,采用对DMTC周期信息和DMTC窗口长度信息单独编码时,各需要2比特和6比特,剩余比特为2比特,MIB-MF具体的信令配置可如下:
通过上述配置,终端通过MF-PBCH,能够获得DMTC配置的全部信息,并且只需要在DMTC窗口内采用诸如同步序列检测,或者根据PCI和子帧号进行CRS检测的方式检测增强DRS中的MF系统信息块,而不需要在每个子帧都进行DRS的检测,减少了终端的功耗。进一步的,本申请实施例中只利用了MIB-MF中未用的比特携带DMTC配置信息,网络设备只需在相应的字段上按照DMTC配置设置相应的比特取值,终端只需通过例如解调MIB-MF的方式,即可得到相应的DMTC配置信息,实现简单,并满足后向兼容性,对只能解调DRS而不能解调增强DRS的终端没有影响。
本申请实施例终端采用上述方式多次进行MF系统信息块的检测后,可对检测到MF系统信息块进行解调。具体在解调过程中,可对多次检测到的MF系统信息块进行合并解调,当然也可单次解调,本申请实施例不做限定。
本申请实施例以下以终端对多次检测到的MF系统信息块进行合并解调的实施过程进行说明。
本申请实施例中,若网络设备多次发送的MF系统信息块内容发生改变,则终端对多次检测到的MF系统信息块进行合并解调,将会解调失败。本申请实施例中可为增强DRS设置MF系统信息块的周期,其中,在同一MF系统信息块周期内的各MF系统信息块的内容一致。在网络设备向终端发送的MIB-MF中携带MF系统信息块周期信息,终端接收到包括有MF系统信息块周期信息的MIB-MF后,通过该包括有MF系统信息块周期信息的MIB-MF,可确定MF系统信息块周期,进而确定进行合并解调的各MF系统信息块是否属于同一MF系统信息块周期的内容未发生改变的MF系统信息块。
本申请实施例中还可为增强DRS设置MF系统信息块内容变更指示信息,所述MF系统信息块内容变更指示信息用于指示所述网络设备当前发送的MF系统信息块的内容与所述网络设备已发送的MF系统信息块的内容是否一致。本申请实施例中网络设备向终端发送的MIB-MF中包括MF系统信息块内容变更指示信息,终端接收到该包括有MF系统信
息块内容变更指示信息的MIB-MF后,通过该包括MF系统信息块内容变更指示信息的所述主系统信息块,可确定MF系统信息块内容变更指示信息,并根据所述MF系统信息块内容变更指示信息,确定所述检测到的MF系统信息块的内容是否发生变更,进而确定该检测到的MF系统信息块与其合并解调的其它系统信息块的内容是否一致。
图13所示为本申请实施例提供的调度MF系统信息块的又一实施流程图,参阅图13所示包括:
S301:网络设备向终端发送MIB-MF,所述MIB-MF中包括MF系统信息块周期信息或MF系统信息块内容变更指示信息。
S302:终端接收网络设备发送的MIB-MF,并通过包括MF系统信息块周期信息或MF系统信息块内容变更指示信息的MIB-MF,确定检测到的MF系统信息块与其合并解调的其它系统信息块的内容是否一致。
本申请实施例中,MF系统信息块周期信息可以理解为是MF系统信息块的周期参数,该周期参数可以有多种表示方式。例如,本申请实施例中可将MF系统信息块的周期参数表示为与DMTC周期的倍数。也即,MF系统信息块周期的计算方式可表示为:DMTC周期与MF系统信息块周期参数的乘积。假设子帧起始位置为子帧0,则无线帧起始位置计算公式为:SFN mod T=0。无线帧周期的计算公式为:T=dmtc-Periodicity*SIB-MF1-Periodicity-mf/10,其中,T为无线帧周期,dmtc-Periodicity为DMTC周期,SIB-MF1-Periodicity-mf为MF系统信息块周期信息。其中,DMTC周期、DMTC窗口与MF系统信息块周期(SIB-MF1的周期)之间的对应关系可如图14所示。图14中,DMTC周期为40ms,MF系统信息块周期参数为2,则MF系统信息块周期为80ms。
本申请实施例中,MF系统信息块的周期配置与上述DMTC周期配置类似,可以取不同的值,与DMTC配置进行组合或者单独配置,不再一一列举。
本申请实施例中,MF系统信息块内容变更指示信息用于指示MF系统信息块内容是否发生变更,可用一个比特位表示。例如一个比特位被置位为1的情况下,可表示网络设备本次发送的MF系统信息块的内容与上次发送的MF系统信息块的内容不一致。一个比特位被置位为0的情况下,可表示网络设备本次发送的MF系统信息块的内容与上次发送的MF系统信息块的内容一致。
本申请实施例中可占用MIB-MF中的未使用比特对上述配置的MF系统信息块周期信息进行编码,利用MIB-MF中的未使用比特对MF系统信息块周期信息进行编码具体的信令配置可如下:
上述信令配置中,SIB-MF1-Periodicity-mf表示MF系统信息块周期信息,表示了MF系统信息块周期的具体取值。
本申请实施例中,MF系统信息块内容变更指示信息也可采用占用MIB-MF中的未使用比特进行编码的方式实现,利用MIB-MF中的未使用比特对MF系统信息块内容变更指示信息进行编码具体的信令配置可如下:
上述信令配置中,SIB-MF1-ChangeInd-mf表示MF系统信息块内容变更指示信息。
其中,若MIB-MF包括MF系统信息块周期信息,则终端可通过该包括MF系统信息块周期信息的MIB-MF后,确定MF系统信息块周期。例如,终端可通过解调该包括MF系统信息块周期信息的MIB-MF后,得到MF系统信息块周期。若MIB-MF包括MF系统信息块内容变更指示信息的MIB-MF,则终端通过该包括MF系统信息块内容变更指示信息的MIB-MF,可确定MF系统信息块内容变更指示。例如,终端可通过解调该包括MF系统信息块内容变更指示信息的MIB-MF后,得到MF系统信息块内容变更指示。
本申请实施例中,终端通过包括MF系统信息块周期或MF系统信息块内容变更指示的MIB-MF,确定MF系统信息块周期或MF系统信息块内容变更指示后,可进一步确定是否可将本次检测到的MF系统信息块和以前接收的其它MF系统信息块进行合并解调,以提高解调成功率。
图15所示为本申请实施例提供的调度MF系统信息块的又一实施流程图,参阅图15所示包括:
S401:网络设备向终端发送MIB-MF,所述MIB-MF中包括MF系统信息块周期信息。
S402:终端接收网络设备发送的MIB-MF,并通过包括MF系统信息块周期信息的MIB-MF,确定MF系统信息块周期。
S403:网络设备发送MF系统信息块,终端检测网络设备发送的MF系统信息块。
S404:终端根据所述MF系统信息块周期确定所述检测到的MF系统信息块与其它系统信息块是否属于同一MF系统信息块周期。
本申请实施例中,所述其它MF系统信息块可以理解为是终端接收检测到的MF系统信息块之前,已接收的MF系统信息块中与所述检测到的MF系统信息块内容一致的系统信息块,也可以理解为是终端将要与本次检测到的MF系统信息块合并解调的MF系统信息块。
本申请实施例中终端可将每次检测到但未成功解调的MF系统信息块进行缓存,将该缓存的MF系统信息块与本次检测到的MF系统信息块进行合并解调。但是在合并解调之前,需确定缓存的MF系统信息块与当前检测到的MF系统信息块的内容是否一致,只有
在一致的情况下,才进行合并解调,在不一致的情况下,可丢弃该内容不一致的已缓存的MF系统信息块。故本申请实施例中上述与本次检测到的MF系统信息块合并解调的其它MF系统信息块可以是终端在解调所述检测到的MF系统信息块之前,未成功解调的MF系统信息块中设定的MF系统信息块,该设定的MF系统信息块为与本次检测到的MF系统信息块内容一致的系统信息块。
S405:终端将检测到的MF系统信息块与所述其它系统信息块进行合并解调。
图16所示为本申请实施例提供的调度MF系统信息块的又一实施流程图,参阅图16所示包括:
S501:网络设备向终端发送MIB-MF,所述MIB-MF中包括MF系统信息块内容变更指示信息。
S502:终端接收网络设备发送的MIB-MF,并通过该包括MF系统信息块内容变更指示信息的MIB-MF,确定MF系统信息块内容变更指示信息。
S503:网络设备发送MF系统信息块,终端检测网络设备发送的MF系统信息块。
S504:终端根据所述MF系统信息块内容变更指示信息,确定所述检测到的MF系统信息块的内容与其它系统信息块的内容是否一致。
S505:终端确定检测到的MF系统信息块的内容与其它系统信息块的内容一致的情况下,将检测到的MF系统信息块与所述其它系统信息块进行合并解调。
本申请上述实施例中,通过在MIB-MF中包括MF系统信息块周期信息或MF系统信息块内容变更指示信息,可占用MIB-MF较少的比特,使终端实现MF系统信息块的检测与解调。但是由于MIB-MF中未包括DMTC周期信息,终端需要在每个子帧检测增强DRS中的MF系统信息块,或者按照DMTC最小周期配置进行DRS中的MF系统信息块的检测,功耗较大。
本申请实施例中为降低终端的功耗,可在上述包括MF系统信息块周期信息或MF系统信息块内容变更指示信息的实施基础上,采用上述实施例涉及的在MIB-MF中包括DMTC配置信息的实现方式。
图17所示为本申请实施例提供的调度MF系统信息块的又一种实施流程图。图17中涉及的执行步骤S601、S602、S603和S604,可与图11中的S101、S102、S103和S104的执行步骤相同,也可与图12中的S201、S202、S203和S204的执行步骤相同,在此不再赘述。本申请实施例图17中以与图12中的S201、S202、S203和S204的执行步骤相同为例进行说明。
图17中涉及的S605、S606、S607、S608和S609的执行步骤可与图15中的S401、S402、S403、S404和S405的执行步骤相同,也可与图16中的S501、S502、S503、S504和S505的执行步骤相同,在此不再赘述。本申请实施例图17中以与图15中的S401、S402、S403、S404和S405的执行步骤相同为例进行说明。
本申请实施例中在MIB-MF中包括DMTC配置信息和MF系统信息块的信令配置可采用如下方式:
其中,上述信令配置中,DMTC-mf表示DMTC配置信息,包括了DMTC周期信息和DMTC窗口长度信息,并利用5bit进行联合编码。DMTC-mf也可以占用6bit对DMTC周期信息和DMTC窗口长度信息进行独立编码,其中DMTC周期信息占用2bit,DMTC窗口长度信息占用4bit。还可以只包括DMTC周期信息,占用2bit。SIB-MF1-Periodicity-mf表示MF系统信息块周期信息。
本申请实施例中采用上述信令配置方式发送MIB-MF以及MF系统信息块时,终端检测MF系统信息块时,可通过第一个增强DRS获得下行同步、PCI,并解调MF-PBCH得到系统带宽,无线帧号,子帧号,以及DMTC配置和MF系统信息块周期配置。如果通过第一个增强DRS,终端没有正确解调到MF系统信息块,则对MF系统信息块数据进行缓存,并在下一个DMTC时间窗内进行DRS检测,如果检测到DRS,则对MF系统信息块进行解调,如果仍未解调成功,则可以和缓存的第一个增强DRS的MF系统信息块数据进行合并解调。如果两次增强DRS不在一个MF系统信息块周期内,则丢弃缓存的MF系统信息块,继续在下一个DMTC窗口内进行增强DRS检测,对于处于MF系统信息块周期内的MF系统信息块数据进行合并解调。
本申请实施例中,网络设备通过MF系统信息块周期,可确定MF系统信息块的变更信息,进而能够根据MF系统信息块的周期确定是否进行合并解调,不会发生合并错误,能够更快解调出MF系统信息块。
本申请实施例中在MIB-MF中包括DMTC配置信息和MF系统信息块内容变更指示信息的信令配置可采用如下方式:
其中,上述信令配置中,DMTC-mf表示DMTC配置信息,包括了DMTC周期信息和DMTC窗口长度信息,并利用5bit进行联合编码。DMTC-mf也可以占用6bit对DMTC周期信息和DMTC窗口长度信息进行独立编码,其中DMTC周期信息占用2bit,DMTC窗口长度信息占用4bit。还可以只包括DMTC周期信息,占用2bit。SIB-MF1-ChangeInd-mf表示MF系统
信息块内容变更指示信息。
本申请实施例中采用上述信令配置方式发送MIB-MF以及MF系统信息块时,终端检测MF系统信息块时,终端每次检测到增强DRS之后解调MF-PBCH,根据SIB-MF1-ChangeInd-mf判断是否能够对MF系统信息块进行合并解调。如果为1,则表示此次MF系统信息块与上次检测到的MF系统信息块内容不同,终端不能进行合并解调,如果为0,则表示与上次检测到的MF系统信息块相同,终端可以进行合并解调。
本申请实施例中采用MF系统信息块内容变更指示信息的配置方式,相对采用MF系统信息块周期信息的配置占用bit较少。
本申请上述实施例中,MIB-MF中包括至少包括DMTC周期,也可以包括DMTC窗口长度信息,使得终端能够在解调MF系统信息块之前获得DMTC配置,从而只需要在增强DRS的可能发送位置检测增强DRS中的MF系统信息块,减少终端功耗。
本申请上述实施例中,MIB-MF中包括MF系统信息块周期信息或MF系统信息块内容变更指示,使终端能够确定检测到的MF系统信息块内容是否变更,在确定检测到的MF系统信息块内容未发生变更的情况下,对MF系统信息块进行合并解调,一定程度上避免终端合并解调错误,提升终端解调MF系统信息块的成功率。
需要说明的是,本申请实施例中,如果MF系统信息块的调度信息,例如TBS、MCS、资源分配等信息也在MIB-MF中承载,和/或如果除DMTC窗口之外,子帧0位置也能够下发增强DRS,也是可以适用上述涉及的MF系统信息块的调度方案的。
其中,若在除DMTC时间窗之外,子帧0位置也下发增强DRS,则终端需要在DMTC时间窗之外的子帧0位置也检测增强DRS中的MF系统信息块,进行MF系统信息块的单独解调或者合并解调。
其中,若MF系统信息块的调度信息也在MIB-MF中承载,终端从MIB-MF中获得了MF系统信息块的调度信息之后,可利用CRS检测来确定MF系统信息块的存在。如果不在MIB-MF中配置DMTC信息,则终端需要在每个子帧对CRS进行检测,检测成功后解调PDSCH。而在子帧5位置处,终端的CRS检测是可以成功的,但是在子帧5并没有MF系统信息块的下发,终端会发生解调错误,合并也会发生错误。
需要说明的是,本申请实施例上述涉及的各方法执行步骤描述以及附图示意的执行步骤并不限定具体执行的先后顺序,例如,本申请实施例并不限定网络设备发送MIB-MF和MF系统信息块的先后顺序,可以先发送MIB-MF,然后发送MF系统信息块,也可MF系统信息块和MIB-MF一同发送。
上述主要从终端和网络设备交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是,终端和网络设备为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。结合本申请中所公开的实施例描述的各示例的单元(器、器件)及算法步骤,本申请实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能,但是这种实现不应认为超出本申请实施例的技术方案的范围。
