Description

一种系统信息区域或网络区域的接入方法及装置
相关申请的交叉引用
本申请主张在2016年7月15日在中国提交的中国专利申请号No.201610561774.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种系统信息区域或网络区域的接入方法及装置。
背景技术
一个无线通信系统可以包括一个或者多个站点(例如基站Node)和用户设备(UE)进行下行传输和上行接收。UE开机之后，为了接入网络，必须至少找到一个站点并通过此站点进行接入。如果一个网络包括多个站点，则UE可能可以通过多个站点中的任意一个站点接入。举例，蜂窝网络中每一个站点可以配置为一个小区(cell)，每个小区发送独立的信号，UE检测不同小区的信号然后选择一个小区接入网络，此过程称为初始接入。
LTE系统中PSS(primary synchronization signal，主同步信号)/SSS(secondary synchronization signal，辅同步信号)的带宽为6PRB(Physical resource block)，即900KHz，限制在每个小区的带宽中心发送，每个小区发送一个PSS/SSS，此信号需要被系统信息区域或网络区域内的所有用户接收到。一个小区的带宽可能有多种可能，包括1.4MHz、5MHz、10MHz、15MHz和20MHz。UE开机进行小区接入之前不知道小区带宽，也不知道小区的频域中心的位置。UE会以100KHz为精度，搜索所有可能的小区中心频点。如果UE检测到了一个PSS/SSS，则UE成功检测到了小区的中心频点，然后UE解调小区的基本信息(master information block)，携带小区系统带宽的信息，然后UE得到小区频率的起始和结束位置。
现有系统主要集中在低频段部署，站点侧的天线数量较少。未来系统会在0.4GHz-100GHz的大带宽上进行部署，低频段和高频段的信道性能差别很大，高频带pathloss(路径损耗)相比低频段高很多，小区覆盖范围急剧减小，需要新的同步和初始接入信号设计保证足够的网络覆盖。另外，未来系统的 天线数量会急剧增多到上百甚至上千，大量天线使用赋形技术产生窄的赋形波束，虽然波束增益可以提高波束内覆盖，但是由于波束变窄，每个波束可以覆盖的角度变表小，小区需要多个波束指向不同的方向，达到全小区的覆盖。
由此，现有的设计不能满足未来系统的需求，未来系统的同步和初始接入信号设计需要考虑这些部署的影响。

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本领域技术人员知道，本公开的实施方式可以实现为一种系统、装置、设备、方法或计算机程序产品。因此，本公开的实施例可以具体实现为以下形式：完全的硬件、完全的软件(包括固件、驻留软件、微代码等)，或者硬件和软件结合的形式。
根据本公开的实施方式，提出了一种系统信息区域或网络区域的接入方法及装置，终端接收系统信息区域或网络区域发送的一个或多个初始接入信号IAS；所述终端根据预先约定的IAS信号在子帧内的发送位置，获取系统信息区域或网络区域的子帧边界；或者所述终端根据预先约定的IAS信号与 系统带宽的映射关系，获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率；或者所述终端通过预先约定的IAS信号与其他信号的时频关系，解调IAS信号对应的其他信号获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率。
在本公开的实施方式中，初始接入信号称为IAS(initial access signal)，需要指出的是IAS是一个宽泛的名称用来指代在UE接入网络的步骤中所需要的信号的总和，可以包括一个信号，也可以包括多个信号。IAS信号可以用以实现一个或者多个功能，比如系统信息区域或网络区域同步，时域/频域同步，系统信息区域或网络区域系统信息接收等等。当然可以理解的是，在本公开的实施方式中IAS信号并不局限于上述例举的功能，该IAS信号也不局限于包括某个具体的信号。
在本公开的实施方式中，IAS信号的功能可以包括给UE提供时频同步的信号。LTE系统中给UE提供时频同步的信号称为同步信号(SYNC)，包括PSS和SSS两部分。时域同步可以达到subframe(子帧)级别(1ms)的同步。每个系统信息区域或网络区域(或者站点)发送其自己的PSS/SSS。每个系统信息区域或网络区域的PSS/SSS的base sequence(基序列)和此系统信息区域或网络区域的系统信息区域或网络区域ID(例如cellID)存在一一对应关系。UE在检测到一个系统信息区域或网络区域的PSS/SSS之后，也对应得到该系统信息区域或网络区域ID(例如CellID)。UE检测不同系统信息区域或网络区域的PSS/SSS，然后选择接入最强信号的系统信息区域或网络区域。
在一些实施例中，参见图1，图中示出了一种系统信息区域或网络区域的接入方法，具体步骤如下：
步骤101、终端接收系统信息区域或网络区域发送的一个或多个初始接入信号IAS；
可选地，系统信息区域或网络区域由一个或者多个站点组成，每个IAS信号由一个站点发送，或者由一组站点发送。上述系统信息区域或网络区域对应的一个示例为小区(cell)，上述站点的一个示例为基站，具体地，在步骤101中，终端接收小区在下行发送的一个或多个IAS信号。
上述IAS信号可以用于表示UE接入网络所需要的信号的总和，该IAS信号可以包括一个信号，也可以包括多个信号，IAS信号可以用于实现一个或多个功能，例如小区同步、时域/频域同步，小区系统信息接收等等，需要说明的是，在本实施例中并不具体限定IAS信号所具有的具体功能和IAS信号所包括的具体信号。
可选地，若所述系统信息区域或网络区域发送一个IAS信号，一个IAS信号在系统信息区域或网络区域所占用的带宽内的任意频率位置发送，且一个IAS信号在子帧内的发送位置由系统信息区域或网络区域与用户预先约定，或者一个IAS信号在系统信息区域或网络区域所占用的带宽内的预定义的频率位置发送，且一个IAS信号在子帧内的发送位置由系统信息区域或网络区域与用户预先约定。
可选地，若所述系统信息区域或网络区域发送多个IAS信号，多个IAS信号中的每个IAS信号在系统信息区域或网络区域所占用的带宽内的任意频率位置发送，且多个IAS信号在子帧内的发送位置由系统信息区域或网络区域与用户预先约定，或者多个IAS信号中的在系统信息区域或网络区域所占用的带宽内的多个预定义的频率位置发送，且多个IAS信号在子帧内的发送位置由系统信息区域或网络区域与用户预先约定。
在本实施例中，多个IAS信号的区分方式可以使用时分复用(TDM)技术区分多个IAS信号、频分复用(FDM)技术区分多个IAS信号和码分复用(CDM)技术区分多个IAS信号其中的一种或者几种的组合，当然也并不限于此。
需要说明的是，在本实施例中，一个系统信息区域或网络区域发送的IAS信号的数量可以在每个系统信息区域或网络区域内不同，在一个系统信息区域或网络区域内的不同时间点也可以不同，具体发送几个IAS信号由系统信息区域或网络区域决定。根据何种条件决定IAS信号的数量是网络的自身实现算法，例如可以根据网络beamforming波束的数量决定，发送IAS信号数量和波束的数量一致，或者可以根据小区内TRP数量决定，每个TRP对应一个IAS信号。
步骤102、所述终端根据接收到的IAS信号获取系统信息区域或网络区 域的子帧边界、系统带宽、起始频率和终止频率中的一项或多项。
具体地，终端根据预先约定的IAS信号在子帧内的发送位置，获取系统信息区域或网络区域的子帧边界；或者，终端根据预先约定的IAS信号与系统带宽的映射关系，获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率；或者，终端通过预先约定的IAS信号与其他信号的时频关系，解调IAS信号对应的其他信号获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率，所述其他信号包含系统信息区域或网络区域的系统带宽、起始频率和/或终止频率。
例如：用户在下行接收一个或者多个IAS信号。当检测到某一IAS信号，则根据此信号的序列，确定其是第几个IAS信号。再根据预先约定的此IAS信号在子帧的发送位置确定子帧的边界。例如系统约定：n个IAS信号的发送时间如图4所示。若用户检测到第3个IAS信号，则其向前两个符号即为子帧边界。
又例如：系统预先定义了IAS序列与系统带宽及其起始和终止频率的映射关系，终端根据上述映射关系获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率。
再例如：终端通过检测其他的系统信号，获取系统信息区域或网络区域的系统带宽、起始频率和/或终止频率，上述其他的系统信号可以是系统信息System Information。此信号可以包含小区的系统带宽及其起始和终止频率信息。
后续终端可根据系统信息区域或网络区域的子帧边界、系统带宽、起始频率和终止频率中的一项或多项进行接入流程的处理，后续的接入过程为相关技术，在此不在敷述。
参见图2，图中示出了一种可能适用第一实施例的系统示意图，下面的实施例中以小区为例进行描述，其中小区的概念可以替换成系统信息区域、网络区域等，一个无线网络覆盖提供广域覆盖。无线网络覆盖多个小区，每个小区覆盖一个不同的范围。一个小区定义为一个无线网络对象，可以供用于接入网络，每个小区对应一个唯一的小区ID，在小区内广播发送。一个小区可以包括一个或者几个TRP(Transmit or Receive Point，发送或接收节点)， 每个TRP包括N个天线，N＝1或大于1。TRP上的天线可以进行波束赋形，下行信号在波束赋形之后在天线上发送。每个波束提供宽覆盖或者窄覆盖，取决于天线数量和波束赋形方式。
在本实施例中，通过执行上述步骤101和步骤102可以实现通过多个IAS信号(例如其具有小区同步、时域/频域同步，小区系统信息接收等功能)获取系统带宽和/或子帧边界，提高系统接入的灵活性和容量，以满足未来多天线系统的需求。

步骤302、所述系统信息区域或网络区域发送一个或多个IAS信号，以使接收到所述IAS信号的终端根据接收到的IAS信号获取系统信息区域或网络区域的子帧边界、系统带宽、起始频率和终止频率中的一项或多项。

下面的实施例中以小区为例进行描述，其中小区的概念可以替换成系统信息区域、网络区域等，不影响本实施例的实施。
在本实施中，获取系统带宽和确定子帧边界的流程具体如下：
步骤A、小区在下行发送多个IAS信号，不同信号采用TDM方式在不同时间发送，不同信号采用不同的基本序列，或者采用相同的基本序列，并使用不同的扰码序列进行加扰。以下假设不同信号采用不同的扰码序列。此 外不同信号在小区带宽内的相同频率位置上发送。
步骤B、用户在下行接收一个或者多个IAS信号。当检测到某一IAS信号，则根据此信号的序列，确定其是第几个IAS信号。再根据预先约定的此IAS信号在子帧的发送位置确定子帧的边界。例如系统约定，n个IAS信号的发送时间如图4所示。若用户检测到第3个IAS信号，则其向前两个符号即为子帧边界。
步骤C、用户根据预定义的小区接入规则，判定是否接入小区。一种接入规则为当用户成功找到某一IAS信号，且此信号强度足够满足接入小区的性能要求，则小区接入成功。
步骤D、若用户接入小区成功，则用户需要获取小区带宽及起始和终止频率。
具体地，一种实现方式是系统预先定义了IAS序列与系统带宽及其起始和终止频率的映射关系。用户根据小区接入时检测到的IAS信号的属性，查找映射关系，获得系统带宽及其起始和终止频率信息。例如，预先约定了基本序列与系统带宽及其起始终止频率的映射关系，如表1所示。若检测到得IAS信号的基本序列为Base sequence2，则系统起始频率为f2，1，系统终止频率为f2，2，系统带宽为f2，2-f2，1。
表1：IAS信号与系统带宽的映射关系
基本序列 起始、终止频率
Base sequence1[f1，1，f1，2]
Base sequence2[f2，1，f2，2]
……
Base sequenceM[fM，1，fM，2]
或者，另一种映射关系如表2所示。其中，f0表示基本序列的中心所在频点，fd表示带宽的基本单位(基本带宽)，m1，1表示基本序列1对应的系统起始频率距离f0相差m1，1个基本带宽，m1，2表示基本序列1对应的系统终止频率距离f0相差m1，2个基本带宽。系统带宽为(m1，1+m1，2)fd。其余基本序列依次类推。这样等效为预先定义了Base sequence与m值的映射关系。
表2：IAS信号与系统带宽的映射关系
基本序列 起始终止频率
Base sequence1[f0-m1，1fd，f0+m1，2fd]
Base sequence2[f0-m2，1fd，f0+m2，2fd]
……
Base sequenceM[f0-mM，1fd，f0+mM，2fd]
另一种实现方式是用户检测其他的系统信号。一种系统信号可以是系统信息System Information。此信号可以包含小区的系统带宽及其起始和终止频率信息。系统预先定义此系统信号与IAS信号的时频关系。图5中给出了一种预先定义的系统信号(表示为MIB)与IAS信号的时频对应关系，图中MIB1，MIB2，…，MIBn可以完全相同。用户根据检测到得IAS信号找到对应的MIB，获得系统带宽信息。
下面的实施例中以小区为例进行描述，其中小区的概念可以替换成系统信息区域、网络区域等，不影响本实施例的实施。
在本实施中，获取系统带宽和确定子帧边界的流程具体如下：
步骤A、小区在下行发送多个IAS信号，不同信号采用FDM方式在相同时间发送，不同信号可以采用相同的序列。此外不同信号在小区带宽内的任意不同频率位置上发送。
步骤B、用户在下行接收一个或者多个IAS信号。当检测到某一IAS信号，根据预先约定的此IAS信号在子帧的发送位置确定子帧的边界。例如系统约定，n个IAS信号的发送时间如图6所示。若用户检测到某一个IAS信号，则其向前两个符号即为子帧边界。
步骤C、用户根据预定义的小区接入规则，判定是否接入小区。一种接入规则为当用户成功找到某一IAS信号，且此信号强度足够满足接入小区的性能要求，则小区接入成功。
步骤D、若用户接入小区成功，则用户需要获取小区带宽及起始和终止频率。
具体地，一种实现方式是系统预先定义了IAS序列与系统带宽及其起始和终止频率的映射关系。用户根据小区接入时检测到的IAS信号的属性，查找映射关系，获得系统带宽及其起始和终止频率信息。例如，预先约定了序 列与系统带宽及其起始终止频率的映射关系，如表3所示。若检测到得IAS信号的序列为Sequence2，则系统起始频率为f2，1，系统终止频率为f2，2，系统带宽为f2，2-f2，1。
表3：IAS信号与系统带宽的映射关系
序列起始终止频率
Sequence1[f1，1，f1，2]
Sequence2[f2，1，f2，2]
……
SequenceM[fM，1，fM，2]
另一种实现方式是用户检测其他的系统信号。一种系统信号可以是系统信息System Information。此信号可以包含小区的系统带宽及其起始和终止频率信息。系统预先定义此系统信号与IAS信号的时频关系。图7中给出了一种预先定义的系统信号(表示为MIB)与IAS信号的时频对应关系，图中MIB1，MIB2，…，MIBn可以完全相同。用户根据检测到得IAS信号，再其之后的第2个信号的相同频率位置解调对应的MIB，获得系统带宽信息。
下面的实施例中以小区为例进行描述，其中小区的概念可以替换成系统信息区域、网络区域等，不影响本实施例的实施。
在本实施中，获取系统带宽和确定子帧边界的流程具体如下：
步骤A、小区在下行发送多个IAS信号，不同信号采用FDM方式在相同时间发送，不同信号可以采用相同的基本序列和不同的扰码序列进行加扰。此外不同信号在小区带宽内的多个预定义的频率位置上发送。
步骤B、用户在下行接收一个或者多个IAS信号。当检测到某一IAS信号，根据预先约定的此IAS信号在子帧的发送位置确定子帧的边界。例如系统约定，n个IAS信号的发送时间如图8所示。若用户检测到某一个IAS信号，则其向前两个符号即为子帧边界。
步骤C、用户根据预定义的小区接入规则，判定是否接入小区。一种接入规则为当用户成功找到某一IAS信号，且此信号强度足够满足接入小区的性能要求，则小区接入成功。
步骤D、若用户接入小区成功，则用户需要获取小区带宽及起始和终止 频率。
具体地，一种实现方式是系统预先定义了IAS序列与系统带宽及其起始和终止频率的映射关系。此映射关系定义了频域中的第N个IAS信号所在频率位置与小区带宽的关系，这样表4的映射关系中，f0表示第N个IAS信号基本序列的中心所在频点。假设N＝1，用户根据小区接入时检测到的IAS信号的扰码序列，确定其是频域上的第几个IAS信号。再根据预定义的频率位置推算出第一个IAS信号所在的频率位置。例如预定义的第一个IAS信号的中心频点为f0，第二个IAS信号的中心频点为f0+Δf，第三个IAS信号的中心频点为f0+2Δf，依次类推，其中Δf表示每个IAS信号的频率间隔。则由接入时的IAS信号即可以得到第一个IAS信号的中心频点。最后根据表4确定小区带宽及起始和终止频率。
表4：IAS信号与系统带宽的映射关系
基本序列起始终止频率

Base sequence2[f0-m2，1fd，f0+m2，2fd]
