Abstract

一种信息指示方法、检测方法及其装置、通信系统。。其中，该信息指示装置，包括：第一发送单元，其用于向用户设备发送指示同步信号块(SS block)在信号发送周期(SS burst set)内的位置的第一指示信息，其中，所述第一指示信息包括至少两部分信息。由此，通过至少两部分信息指示同步信号在信号发送周期内的位置，以支持UE侧的帧定时，解决了目前存在的问题。

Description

信息指示方法、检测方法及其装置、通信系统 技术领域
本发明涉及通信领域，特别涉及一种信息指示方法、检测方法及其装置、通信系统。
背景技术
在长期演进(LTE，Long Term Evolution)系统中，用户设备(user equipment，UE)通过检测同步信号实现下行同步(包括频率和符号同步)，获取单个系统帧的定时边界并确定物理小区标识(Physical Cell Identifier，PCI)。例如,网络侧周期性地发送位于不同时间位置的两组同步信号，在每个发送周期内，该两组同步信号中的每组同步信号均包含主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)，其中两组同步信号中的PSS序列相同，而SSS序列不同，这样，用户设备可根据检测到的SSS序列来确认该同步信号在该发送周期内的位置，从而可获知单个系统帧的定时边界。
另外，UE不仅在初始接入小区时需要检测同步信号实现下行同步；此外，为了支持移动性，UE初始接入小区后会不停地搜索邻居小区，取得同步并估计该小区信号的接收质量，从而决定是否进行小区切换或小区重选。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在未来无线通信系统，例如5G、新无线(New Radio，NR)系统中，采用更高频率更大带宽的无线频谱资源，如厘米波、毫米波等来应对持续增长的无线业务量及各种各样的新业务，然而高频段会遭受严重的传输损耗。为了解决该问题，可以采用大规模天线技术(massive MIMO)，通过较大的波束成形增益对抗严重的传输衰减。由于基站的单个波束只能覆盖小区内某一方向范围内的UE，因此，基站需要采用多个波束时分地发送同步信号及物理广播信道(Physical Broadcast Channel，PBCH)， 才能保证小区内所有的UE都能接收到同步信号及PBCH。由于UE侧搜索时间应尽可能低，基站在单个信号发送周期内发送的同步信号数量也就相应增加。
例如，基站以信号发送周期(如SS burst set发送周期)为周期来发送同步信号块(SS block)，该SS block可包括PSS，SSS，和/或PBCH，在每个发送周期内发送的SS block为一个或多个(如64个)，在发送多个SS block时，不同的SS block可能采用不同数量和/或方向的波束发送。目前还没有有效的指示SS block在信号发送周期中的位置的方案。在这种情况下，若直接扩展现有的指示方式，即采用SSS序列来指示一个SS block在SS burst set内的位置，则可能存在诸多方面的问题。例如，一方面，SSS序列数可能并不足以指示信号发送周期内所有的同步信号的位置；另一方面，通过扩展的SSS序列数来进行指示也会增加UE侧的盲检复杂度和搜索时间。
为了解决上述问题，本发明实施例提供一种信息指示方法、检测方法及其装置、通信系统，能够指示同步信号在信号发送周期内的位置的方法，以支持UE侧的帧定时。
根据本实施例的第一方面，提供了一种信息指示方法，该方法包括：
向用户设备发送指示同步信号块(SS block)在信号发送周期(SS burst set)内的位置的第一指示信息，其中，该第一指示信息包括至少两部分信息。
根据本实施例的第二方面，提供了一种信息检测方法，其中，该方法包括：
接收网络侧指示同步信号块(SS block)在信号发送周期(SS burst set)内的位置的第一指示信息，该第一指示信息包括至少两部分信息。
根据本实施例的第三方面，提供了一种信息配置方法，其中，该方法包括：
将至少部分DMRS放置在同步信号所在的符号。
根据本实施例的第四方面，提供了一种信息指示装置，该装置包括：
发送单元，其用于向用户设备发送指示同步信号块(SS block)在信号发送周期(SS burst set)内的位置的第一指示信息，其中，该第一指示信息包括至少两部分信息。
根据本实施例的第五方面，提供了一种信息检测装置，其中，该装置包括：
接收单元，其用于接收网络侧指示同步信号块(SS block)在信号发送周期(SS burst set)内的位置的第一指示信息，该第一指示信息包括至少两部分信息。
根据本实施例的第六方面，提供了一种信息配置装置，其中，该装置包括：
处理单元，其用于将至少部分DMRS放置在同步信号所在的符号。
本发明实施例的有益效果在于，根据本发明实施例，通过至少两部分信息指示同步信号在信号发送周期内的位置，以支持UE侧的帧定时，解决了目前存在的问题。

下面结合附图对本发明实施例进行说明。
实施例1
图1是本实施例1的信息指示方法流程图，应用于网络设备侧。如图1所示，该方法包括：
步骤101，向用户设备(UE)发送指示同步信号块(SS block)在信号发送周期内的位置的第一指示信息，其中，该第一指示信息包括至少两部分信息。
由上述实施例可知，通过至少两部分信息指示同步信号在信号发送周期内的位置，以支持UE侧的帧定时，解决了目前存在的问题。
在本实施例中，该至少两部分信息中的每部分信息分别用于指示该SS block的位置的部分位置信息。这样，在用户设备接收到每部分信息后，可利用该每部分信息来确定该SS block的部分位置信息，进而根据该部分位置信息确定SS block在信号发送周期中的位置，以获得单个系统帧的定时边界。例如，该SS block的位置可通过索引来表征，在这种情况下，SS block的位置的部分位置信息是指SS block索引的部分信息，在该索引采用信息比特表示时，该部分信息是指部分比特。
在本实施例中，该第一指示信息中的每部分信息可以通过以下信息来指示：
信号序列、与解调参考信号(DMRS)序列相关的信息或与物理广播信道(PBCH)相关的信息，但本实施例不限于上述信息，还可采用其他信息来指示，此处不再一一列举。
由上述实施例可知，通过多个信息来指示同步信号在信号发送周期内的位置，以支持UE侧的帧定时，解决了目前存在的问题。
下面以未来无线通信系统中网络侧发送的同步信号(如SS block)为例，对指示该SS block的位置的方法进行详细说明。但需要说明的是，该方法不限于该通信系统，对于涉及到同步信号的指示的其他通信系统均适用。
图2是未来无线通信系统中基站发送同步信号示意图，如图2所示，网络侧设备，如基站以信号发送周期(如SS burst set)为基本周期发送至少一个SS block，如图2所示，每个信号发送周期可发送K个SS block，不同的SS block可以采用相同或不同数量和/或方向的波束(包括全向波束)发送，其中K大于等于1，图2所示为8个，单个系统帧长度和信号发送周期分别为10ms和20ms，但本实施例K的数量、单个系统帧长度、信号发送周期、每个SS block的发送波束的数量和方向等均不限于上述实施例，此处不再一一列举。
在本实施例中，网络侧周期性发送的SS block可用于支持小区同步、测量、信息广播等，例如，该SS block可包括同步信号、和/或广播信道、和/或参考信号等，如图3所示；例如，该同步信号可以是主同步信号(PSS/NR-PSS)，和/或辅同步信号(SSS/NR-SSS)等，该广播信道可以是物理广播信道(PBCH/NR-PBCH)。
图3是本实施例中同步信号块结构示意图，如图3所示，SS block可以包含PSS，SSS，此外还可包含PBCH。该同步信号块的结构不限于图3所示的结构，还可采用其他结构，例如包含参考信号等。
在本实施例中，该SS block的位置可通过索引(index)来表征，该至少两部分信息中的每部分信息分别用于指示该SS block索引的部分信息(如部分比特)。
在一个实施方式中，SS block的位置可通过该SS block在整个信号发送周期(如SS burst set)中的索引表征。例如，在该索引采用信息比特表示时，该索引的信息比特是Y位比特，该至少两部分信息中的每部分信息分别用于指示该Y位比特中的部分比特。
例如，待指示的SS block索引的信息比特为Y位，在采用数量为X的部分信息来指示该SS block索引时，可以将Y位比特分为X部分，每部分的比特数量分别为Y1,Y2,…,YX，其中，Y1+Y2,+…+YX＝Y，X部分信息中的每部分信息分别指示Y1,Y2,…,YX位比特，其中X大于等于2，且为整数。其中，Y1、Y2…、Yx可相同也可不同。
在一个实施方式中，SS block的位置通过该SS block在所属信号发送周期(如SS burst set)内所在SS block组的组索引和在该SS block组中的索引表征，可以使用至少两部分信息分别指示该组索引的全部或部分比特，以及在该SS block组中的索引全部或部分比特。
例如，在采用数量为X的部分信息来指示该SS block索引时，组索引的信息比特为Y1，组中SS block索引的信息比特为Y2时，可以将Y1分为X1部分，每部分的比特数量分别为Y11,Y12,…,Y1X，其中，Y11+Y12,+…+Y1X＝Y1，X1部分信息中的每部分信息分别指示Y11,Y12,…,Y1X位比特，可将Y2分为X2部分，每部分的比特数量分别为Y21,Y22,…,Y2X，其中，Y21+Y22,+…+Y2X＝Y2，X2部分信息中的每部分信息分别指示Y21,Y22,…,Y2X位比特，其中X1+X2＝X，X大于等于2，X1和X2大于等于1，且均为整数。其中Y11,Y12,…,Y1X可相同或不同，Y21,Y22,…,Y2X可相同或不同。
以下分别说明该至少两部分(X个)信息如何指示该SS block的位置的部分信息。
图4和图5分别是SS block在信号发送周期中的位置表征方式示意图，如图4所示，SS block在信号发送周期，如SS burst set中的位置可以通过该SS block在整个信号发送周期中的索引(0，1，…，M×N－1)表征，其中M×N表示SS block的数量；如图5所示，将在信号发送周期，如SS burst set中发送的SS block分为多个组，如分为M个SS block组，且每个组的组索引分别为0，1，…，M-1，每个组即为SS burst set中的SS block集合的一个子集，每个组内包括连续发送或者非连续发送的多个SS block，每个组内SS block的索引分别为0，1，…，N-1，且每个组中的SS block数量相同，该SS block的位置通过该SS block在所属的信号发送周期内所在SS block组的组索引(Group index)和在该SS block组中的索引(SS block index)表征。需要指出的是，图中所示每个组中的SS block相同，但本发明不限于此。
例如，在X＝2时，通过两部分信息分别指示SS block的位置的部分信息。
在采用图4所示的表征方式时，一部分信息用于指示该SS block索引的高位，另一部分信息用于指示该SS block索引的低位，或者在采用图5所示的表征方式时，一部分信息用于指示该SS block组的组索引，另一部分信息用于指示该SS block在该SS block组中的索引。
例如，如图4所示，一个SS burst set中有M×N个SS block，SS block索引采用信息比特表示，该信息比特的个数Y为：
Figure PCTCN2017083313-appb-000001
该第一指示信息的一部分信息用于指示Y位中的高P(0<P<Y)位比特信息，另一部分信息用于指示Y位中的低(Y-P)位比特信息，这样，UE分别根据两部分信息确定其所指示的SS block索引的部分信息，从而确定SS block在SS burst set内的位置，获得帧定时。
例如，如图5所示，一个SS burst set中有M×N个SS block，将M×N个SS block分为M个组，组索引分别为0～M-1，在一个组中有N个SS block，每个SS block的索引分别为0～N-1，组索引和SS block在组中的索引均采用信息比特表示，第一指示信息的一部分信息指示组的组索引0～M-1，共
Figure PCTCN2017083313-appb-000002
个比特，第一指示信息的另一部分信息指示SS block在该组中的索引0～N-1，共
Figure PCTCN2017083313-appb-000003
个比特，UE分别根据两部分信息确定其所指示的SS block索引的部分信息，从而确定SS block在SS burst set内的位置，获得帧定时。
例如，在X＝4时，通过四部分信息分别指示SS block的位置的部分信息。
在采用图4所示的表征方式时，四部分信息分别用于指示该SS block索引的4部分比特，例如最高位，次高位，次低位，最低位(最高位，次高位，次低位，最低位的比特数量可以相同，可以不同)，或者在采用图5所示的表征方式时，两部分信息用于指示该SS block组的组索引的高位和低位(高位和低位的比特数量可以相同，可以不同)，另两部分信息用于指示该SS block在该SS block组中的索引的高位和低位(高位和低位的比特数量可以相同，可以不同)，或者其中一部分信息用于指示该SS block组的组索引的全部比特，另三部分信息用于指示该SS block在该SS block组中的索引的高位，中位和低位(高位，中位和低位的比特数量可以相同，可以不同)，或者，其中三部分信息用于指示该SS block组的组索引的高位，中位和低位(高位，中位和低位的比特数量可以相同，可以不同)，另一部分信息用于指示该SS block在该SS block组中的索引的全部比特，本实施例并不以此作为限制。
例如，如图4所示，一个SS burst set中有M×N个SS block，SS block索引采用信息比特表示，该信息比特的个数Y为：
Figure PCTCN2017083313-appb-000004
该第一指示信息的四部分信息用于指示Y位中的高P1(0<P1<Y)位比特信息，次高P2位比特信息，次低P3位比特信息，低P4位比特信息(P1+P2+P3+P4＝Y)，这样，UE分别根据四部分信息确定其所指示的SS block索引的部分信息，从而确定SS block在SS burst set内的位置，获得帧定时。
例如，如图5所示，一个SS burst set中有M×N个SS block，将M×N个SS block分为M个组，组索引分别为0～M-1，在一个组中有N个SS block，每个SS block的索引分别为0～N-1，组索引和SS block在组中的索引均采用信息比特表示，第一指示信息的两部分信息指示组的组索引0～M-1的高位P1和低位P2，共
Figure PCTCN2017083313-appb-000005
个比特，其中，第一指示信息的另两部分信息指示SS block在该组中的索引0～N-1的高位P3和低位P4，共
Figure PCTCN2017083313-appb-000006
个比特，或者，第一指示信息的一部分信息指示组的组索引0～M-1，共
Figure PCTCN2017083313-appb-000007
个比特，其中，第一指示信息的另三部分信息指示SS block在该组中的索引0～N-1的高位P1，中位P2和低位P3，共
Figure PCTCN2017083313-appb-000008
个比特，或者第一指示信息的一部分信息指示组的组索引0～M-1的高位P1，中位P2和低位P3，共

Figure PCTCN2017083313-appb-000010
个比特，UE分别根据四部分信息确定其所指示的SS block索引的部分信息，从而确定SS block在SS burst set内的位置，获得帧 定时。
以上仅以X＝2或4为例对该至少两部分信息进行说明，在X为其他值时，其指示方式类似，此处不再一一举例。
在本实施例中，如前所述，该第一指示信息中的的每部分信息可以通过以下信息来指示：
信号序列、与解调参考信号(DMRS)序列相关的信息或与物理广播信道(PBCH)相关的信息，例如，该信号序列可包括SSS序列或解调参考信号(DMRS)序列或第三同步信号(tertiary synchronization signal，TSS)序列；该与DMRS序列相关的信息包括DMRS序列所占时频资源的频域偏移、时域偏移或DMRS序列的正交覆盖码(OCC)；该与PBCH相关的信息包括：PBCH负载、或PBCH的加扰序列、或PBCH中包含的比特信息所采用的循环移位、或加扰PBCH所携带的循环冗余校验(CRC)的CRC掩码(mask)。但该每部分信息并不限于上述信息，还可包括其他信息，此处不再一一列举。
例如，在第一指示信息包括两部分信息时，可利用SSS序列与DMRS序列所占时频资源的频域偏移、时域偏移DMRS序列的正交覆盖码(OCC)中的一种分别指示两部分信息；或者利用SSS序列与PBCH负载、PBCH的加扰序列、PBCH中包含的比特信息所采用的循环移位、加扰PBCH所携带的循环冗余校验的CRC mask中的一种分别指示两部分信息；或者利用DMRS序列与DMRS序列所占时频资源的频域偏移、时域偏移DMRS序列的正交覆盖码(OCC)中的一种分别指示两部分信息；或者利用DMRS序列与PBCH负载、PBCH的加扰序列、PBCH中包含的比特信息所采用的循环移位、加扰PBCH所携带的循环冗余校验的CRC mask中的一种分别指示两部分信息；或者利用DMRS序列所占时频资源的频域偏移、时域偏移、DMRS序列的正交覆盖码(OCC)中的一种，与PBCH负载、PBCH的加扰序列、PBCH中包含的比特信息所采用的循环移位、加扰PBCH所携带的循环冗余校验的CRC mask中的一种分别指示两部分信息，或者可利用TSS序列与DMRS序列所占时频资源的频域偏移、时域偏移DMRS序列的正交覆盖码(OCC)中的一种分别指示两部分信息；或者利用TSS序列与PBCH负载、PBCH的加扰序列、PBCH中包含的比特信息所采用的循环移位、加扰PBCH所携带的循环冗余校验的CRC mask中的一种分别指示两部分信息。
例如，在第一指示信息包括X(X大于2)部分信息时，可以利用SSS序列，DMRS序列，TSS序列中的S1种，与DMRS序列所占时频资源的频域偏移、时域偏移、DMRS序列的正交覆盖码(OCC)中的S2种，以及PBCH负载、PBCH的加扰序列、PBCH中包含的比特信息所采用的循环移位、加扰PBCH所携带的循环冗余校验(CRC)的CRC mask的S3种分别指示X部分信息，其中，S1+S2+S3＝X，且S1为小于等于3的整数，S2为小于等于3的整数，S3为小于等于4的整数，本实施例并不以此作为限制。
由此，该至少两部分信息可以显示的指示，例如通过上述PBCH负载来指示，也可以隐式的指示，即通过重用已有的信号序列，信号序列资源位置，信号序列的编码方式，PBCH的编码调制方式等隐式的指示，例如通过SSS序列或DMRS序列或TSS序列本身；或DMRS序列所占时频资源的频域偏移、时域偏移或DMRS序列的OCC；或PBCH的加扰序列、或PBCH中包含的比特信息所采用的循环移位、或加扰PBCH所携带的CRC的CRC mask等隐式的指示，可以节省信令开销。
因此，通过上述至少两种信息分别指示该第一指示信息中的至少两部分信息，可以避免现有技术中的指示方式存在的诸多问题。
在本实施例中，该方法还包括：
步骤100，配置该信息与该信息所指示的用于确定SS block的位置的部分位置信息的映射关系。
例如，预定义或预配置信号序列(SSS、DMRS、TSS序列)、与物理广播信道(PBCH)相关的信息(PBCH负载、PBCH负载、和/或PBCH的加扰序列、和/或PBCH中包含的比特信息所采用的循环移位、和/或加扰PBCH所携带的循环冗余校验(CRC)的CRC mask)、与DMRS序列相关的信息(DMRS序列所占资源的频域偏移、时域偏移与DMRS序列的正交覆盖码OCC)与上述信息所指示的用于确定SS block的位置的部分位置信息的映射关系，该映射关系是UE侧预定义或预配置的，或者是由基站通知给UE的，UE根据该第一指示信息以及该映射关系分别确定指示SS block位置的至少两部分位置信息，并根据该至少两部分位置信息确定该SS block在SS burst set内的位置，以便获取帧定时。
以下分别对以上信息如何指示部分位置信息进行说明，该部分位置信息可以是SS block索引的部分信息(部分比特，例如表征SS block在整个信号发送周期内的 SS block索引的部分比特，或者表征组索引的全部或部分比特，组中索引的全部或部分比特，为方便说明，将该部分信息统称为索引l，且每一部分比特数为X’，L1表示索引值，均为正整数，其中，L1+1等于2X'。
1、信号序列
1)通过不同的SSS序列指示相应的索引l，需要预先配置SSS序列和索引l的映射关系，如表1所示，在PCI为1时，SSS序列与索引l的映射关系。

其中，

与l一一对应，其中，m＝0，1，…，LSSS-1，LSSS表示SSS序列的长度，L为正整数。UE根据上述映射关系以及检测到的SSS序列即可以确定索引l。
2)通过不同的PBCH的解调参考信号(DMRS)序列指示不同的索引l，需要预先配置DMRS序列和索引l的映射关系，下表2为DMRS序列与索引l的映射关系。
表2

与l一一对应，其中，m＝0，1，…，LDMRS-1，LDMRS表示DMRS序列的长度，L为正整数。UE根据上述映射关系以及检测到的DMRS序列即可以确定索引l。
与1)中映射关系不同的是，DMRS序列和SS block索引的高位或低位的映射关系还可以通过DMRS序列的生成来配置，即至少基于需要指示的SS block的部分位置信息生成DMRS序列，由此确定DMRS序列与其所指示的SS block的部分位置信息的映射关系。
例如，基于SS block索引生成DMRS序列为伪随机序列，则可采用如下方式生成：

c(n)＝(x1(n+NC)+x2(n+NC))mod 2
x1(n+31)＝(x1(n+3)+x1(n))mod 2
x2(n+31)＝(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod 2
其中，NC＝1600，并且第一个m序列的初始值为x1(0)＝1,x1(n)＝0,n＝1,2,...,30。第二个m序列的初始值为

若DMRS序列仅基于SS block索引生成，第二个m序列的初始值例如为：

若DMRS序列基于SS block索引及其他信息生成，例如，第二个m序列的初始值为

若DMRS序列基于SS block索引，PCI、及CP长度生成，例如，第二个m序列的初始值为

其中，
Figure PCTCN2017083313-appb-000023
其中，UE根据检测到的DMRS序列可以确定索引l。
3)通过不同的TSS序列指示相应的索引l，需要预先配置TSS序列和索引l的映射关系，其具体配置方式与1)类似，此处不再赘述。
2、与物理广播信道(PBCH)相关的信息
1)通过不同的PBCH负载指示不同的索引l，其中，PBCH负载表示PBCH所包含的比特信息，需要预先配置PBCH所包含的比特信息和索引l的映射关系，下表3为PBCH所包含的比特信息与索引l的映射关系；
表3
l PBCH中包含的比特信息
1 0.....1
2 0...10
… …
L1 11…1
其中，UE根据上述映射关系以及接收到的PBCH即可以确定索引l。
2)通过不同的PBCH的加扰序列指示不同的索引l，其中，PBCH的加扰序列基于不同的方式生成的，需要预先配置不同的加扰序列和索引l的映射关系，UE根据上述映射关系，通过检测PBCH的加扰序列即可以确索引l，其中加扰序列的生成方式与DMRS序列的生成方式类似，映射关系的配置方式类似，此处不再重复。
3)通过PBCH中包含的比特信息所采用的不同的循环移位指示不同的索引l，需要预先配置不同的循环移位和索引l的映射关系，下表4为PBCH中包含的比特信息所采用的不同的循环移位与索引l的映射关系；
表4
l PBCH中包含的比特信息
1 xZ......x2x1x0
2 .....x2x1x0xZ
… …
L1 x0xZ.....x2x1
其中，PBCH包含Z个比特，例如循环移位步长为1，存在Z种不同的比特循环移位，可以分别表示不同的索引l，其中Z等于L1，UE根据上述映射关系以及接收 到的PBCH所采用的循环移位即可以确定索引l。
4)通过加扰PBCH所携带的不同的循环冗余校验(CRC)的CRC mask指示不同的索引l，其中，在发送SS block时，根据该SS block的index选用相应的CRC mask加扰PBCH所携带的传输块的CRC，需要预先配置CRC mask序列和索引l的映射关系，下表5为PBCH所包含的比特信息与索引l的映射关系；
表5
l CRC mask
1 <0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>
2 <1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1>
… …
L1 <1,0,1,0,1,0,1,0,1,0,1,0,1,0,1，0>
UE根据该映射关系，盲检该SS block中的PBCH所携带的传输块的CRC所使用的CRC mask即可以确定索引l。
3、与DMRS序列相关的信息
1)通过DMRS序列所占用的不同的时频资源位置指示不同的索引l，其中，时频资源位置可以通过时频资源的频域偏移或时域偏移来表示，需要预先配置DMRS所占用的时频资源的频域偏移或时域偏移和索引l的映射关系，UE通过检测DMRS占用的时频资源的频域偏移或频域偏移以及该映射关系即可以确定索引l。
2)DMRS序列的OCC
通过DMRS序列所使用的不同OCC来指示不同的索引l，需要预先配置OCC和索引l的映射关系，下表6为OCC与索引l的映射关系；
表6
l OCC
1 [+1 +1 +1 +1]
2 [+1 -1 +1 -1]
… …
L1 [-1 +1 +1 -1]
UE通过检测DMRS所使用的OCC以及该映射关系即可以确定索引l。
以上对上述信息如何指示部分位置信息进行了说明。需要说明的是，以上信息指示不同的部分位置信息的方法相同，可以使用其中的任意X种分别指示SS block索引的不同的部分信息(部分比特)，例如，通过SSS序列指示SS block索引的高位，通过PBCH负载指示SS block索引的低位，反之亦然，或者，也可以通过SSS序列指示SS block索引的高位，通过DMRS序列指示SS block索引的低位，反之亦然，此处仅以X＝2为例进行说明，对于X大于2的情况类似，此处不再一一举例。
在本实施例中，该方法还可以包括：
步骤102(可选)，在该第一指示信息的至少一部分通过信号序列来指示时，其向用户设备发送指示对检测到的同步信号块(SS block)在信号发送周期(SS burst set)内的位置或部分位置进行确认的信息。
由此，在UE在根据该第一指示信息获取SS block的位置或部分位置后，还可以根据该进行确认的信息、确认该SS block的位置或部分位置是否正确。
在本实施例中，该进行确认的信息可以采用与PBCH相关的信息，例如PBCH负载、和/或PBCH的加扰序列、和/或PBCH中包含的比特信息所采用的循环移位、和/或加扰PBCH所携带的循环冗余校验(CRC)的CRC来指示，其具体实施方式参考实施例1中的信息2，此处不再赘述。
在本实施例中，SS block中包括PSS，SSS和/或PBCH和/或用于PBCH解调的DMRS，图6是该SS block结构示意图，如图6所示，可以将至少部分DMRS放置在同步信号所在的符号。

例如，分别通过DMRS的OCC和PBCH的加扰序列指示第一指示信息的两部分信息(SS block索引的高位和低位)，网络设备侧发送包含该DMRS和PBCH的SS block，UE根据接收到的SS block，检测DMRS序列，根据DMRS的OCC与预先获得的DMRS的OCC与索引的映射关系确定SS block索引的高位，UE根据接收到的PBCH与预先获得的PBCH的加扰序列与索引的映射关系确定SS block索引的低位，从而确定SS block索引，进而确定SS block在SS burst set内的位置，获取帧定时。
以上仅示例性的说明了如何指示第一指示信息的两部分信息，但本实施例并不以此作为限制，该第一指示信息可以包括3部分以上的信息，且每部分信息还可以通过其他信息指示，具体可以参考实施例1，此处不再赘述。
