Abstract

本发明公开了通过主同步信号进行指示的方法、基站、终端设备及系统，能够通过PSS中的多个子同步信号在无线帧中的位置来表示工作模式，达到了通过PSS指示网络的工作模式的目的。本发明实施例方法包括：基站确定网络的工作模式；所述基站根据确定的工作模式生成主同步信号PSS，所述PSS包含多个子同步信号，其中，不同的工作模式对应不同位置的子同步信号；所述基站向终端设备发送所述PSS。

Description

通过主同步信号进行指示的方法、基站、终端设备及系统 技术领域
本发明涉及通信技术领域，尤其涉及通过主同步信号进行指示的方法、基站、终端设备及系统。
背景技术
随着机器到机器(Machine to Machine，M2M)通信应用的飞速扩展，其市场需求和规模呈现爆发式增长。通信双工模式分为频分双工(Frequency Division Duplex，FDD)和时分双工(Time Division Duplex，TDD)。FDD双工模式指的是在分离的两个对称频率信道上，系统进行接收和传送，通过保证频段的方式来分离接收和传送信道，TDD双工模式指的是在同一频率信道的不同时隙上，系统进行接收和传送，通过保证时间的方式来分离接收和传送信道。由于应用场景、地方法规和频谱划分的多样性，M2M通信系统需要同时支持FDD双工模式和TDD双工模式，因此基站要通知终端设备具体的双工模式。
当前，在长期演进(Long Term Evolution，LTE)中，TDD双工模式和FDD双工模式是由主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)的相对位置来指示的，FDD双工模式中，PSS位于无线帧的第1和第11个时隙的最后一个正交频分复用(Orthogonal Frequency Division Multiple，OFDM)符号，SSS位于PSS前面的一个OFDM符号，TDD双工模式中，PSS位于无线帧的第3和第13个时隙，SSS早于PSS三个符号。终端设备首先检测PSS，完成基本的时频同步，然后检测SSS，如果SSS位于PSS前三个符号，则判断系统的双工模式是TDD双工模式，如果SSS位于PSS前一个符号，则判断系统的双工模式是FDD双工模式。
但是，上述通过PSS和SSS的相对位置来指示具体的双工模式的方法不适用于M2M通信系统，因为在M2M通信系统中，PSS和SSS可能都要占用一个子帧，所以没有过多的资源能够供PSS和SSS使用，无法依靠PSS和SSS的相对位置来指示具体的双工模式，同理，也无法依靠PSS和SSS的相对位 置来指示部署场景等。

具体实施方式
本发明实施例提供了通过主同步信号PSS进行指示的方法、基站、终端设备及系统，能够通过PSS中的多个子同步信号在无线帧中的位置来表示工作模式，达到了通过PSS指示网络的工作模式的目的。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发 明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
虽然在前述背景技术部分以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本发明不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如全球移动通信系统(Global System for Mobile Communication，GSM)，移动通信系统(Universal Mobile Telecommunications Systemc，UMTS)，码分多址接入(Code Division Multiple Access，CDMA)系统，以及新的网络系统等。下面以LTE系统为例进行具体实施例的介绍。
本发明实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为系统、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(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用 户装备(User Equipment)。
本发明实施例所涉及基站，该基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。该基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本申请并不限定。
下面结合具体实施例对本发明中通过主同步信号进行指示的方法进行说明:
请参阅图1，本发明实施例中通过主同步信号进行指示的方法一个实施例包括：
101、基站确定网络的工作模式；
本实施例中，工作模式包括双工模式和/或部署场景，部署场景可以为部署方式、系统帧号和小区标识(Identity，ID)中的一种或者几种，部署方式包括独立部署方式以及非独立部署方式。M2M通信系统频谱有多种部署方式，比如，可以部署到现有通信系统频带内，例如LTE、全球移动通信系统(Global System for Mobile communications，GSM)等，也可以部署到现有通信系统频带的保护带中，像LTE、GSM的保护带，也可以独立部署到一段独有的频谱中，不同的部署方式会有不同的场景和需求，从而会有不同的设计，为了使得终端设备能够兼容不同的部署方式，需要在终端设备接入网络后用一定的方式来通知终端设备具体的部署方式。
102、基站根据确定的工作模式生成主同步信号PSS，该PSS包含多个子同步信号，其中，不同的工作模式对应不同位置的子同步信号；
本实施例中，子同步信号在无线帧中可以单独占用一个子帧，也可以占用一个子帧中的一个符号。
103、基站向终端设备发送该PSS。
本实施例中，在基站生成PSS后，基站向终端设备发送该PSS。
需要说明的是，终端设备在接收到该PSS后，能够根据PSS中的多个子同步信号在无线帧内的位置确定工作模式。
本实施例中，通过PSS中的多个子同步信号在无线帧中的位置来表示工作模式，工作模式可以为双工模式，也可以为部署场景，避免了现有技术中通过PSS和SSS的相对位置来指示双工模式和/或部署场景的方法不适用于M2M通信系统的问题，由此可见，本发明通过PSS中的多个子同步信号在无线帧中的位置来表示工作模式，达到了通过PSS指示网络的工作模式的目的。
可选的，在本发明的一些实施例中，基站确定网络的工作模式包括：基站确定网络的工作模式为双工模式；
基站根据确定的工作模式生成主同步信号PSS，该PSS包含多个子同步信号，其中，不同的工作模式对应不同位置的子同步信号，包括：
基站根据确定的双工模式生成PSS，该PSS包含第一子同步信号和第二子同步信号，在TDD双工模式下承载第一子同步信号的子帧位置和在FDD双工模式下承载第一子同步信号的子帧位置不同，和/或在TDD双工模式下承载第二子同步信号的子帧位置和在FDD双工模式下承载第二子同步信号的子帧位置不同。
需要说明的是，第一子同步信号和第二子同步信号可以分别为根指数为1、-1的Zadoff-Chu序列，简称ZC序列；
第一子同步信号可以为zc(n)1＝e-jπn(n+1+2q)/L,n＝0,1,...,L-1,q∈Z；
第二子同步信号可以为zc(n)2＝ejπn(n+1+2q)/L,n＝0,1,...,L-1,q∈Z；
其中L表示ZC序列的长度。
需要说明的是，为了保证终端设备能够区分双工模式，在TDD双工模式下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置之间的距离等于在FDD双工模式下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置之间的距离的条件下，需要满足在TDD双工模式下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置的顺序与在FDD双工模式下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置的顺序不同，并且PSS的发送周期为至少两个无线帧的长度，举例来说，假如在TDD双工模式下，承载第一子同步信号的子帧位置为子帧0，承载第二子同步信号的子帧位置为子帧5，在FDD双工模式下，承载第一子同步信号的子帧位置为子帧1，承载第二子同步信号的子帧位置为子帧6，这种情况下终端设备是不能区分双 工模式的，正确的方式是在FDD双工模式下，承载第一子同步信号的子帧位置为子帧6，承载第二子同步信号的子帧位置为子帧1，同时PSS的发送周期为至少两个无线帧的长度。
进一步可选的，TDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧0，TDD双工模式下承载第二子同步信号的子帧位置为无线帧内的子帧5；或者，TDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧5，TDD双工模式下承载第二子同步信号的子帧位置为无线帧内的子帧0。
需要说明的是，若PSS包含两个以上的子同步信号，比如PSS包含四个子同步信号，那么可以有：TDD双工模式下承载第一子同步信号和第三子同步信号的子帧位置为无线帧内的子帧0，TDD双工模式下承载第二子同步信号和第四子同步信号的子帧位置为无线帧内的子帧5；或者，FDD双工模式下承载第一子同步信号和第三子同步信号的子帧位置为无线帧内的子帧5，FDD双工模式下承载第二子同步信号和第四子同步信号的子帧位置为无线帧内的子帧0。需要说明的是，上述子同步信号的分布方案只是实施例的一种，本发明不限定于上述分布方案。另外，多个子同步信号位于无线帧内的同一个子帧上指的是多个子同步信号位于一个子帧内的不同符号上。
可选的，在TDD双工模式下承载第一子同步信号的子帧位置和在FDD双工模式下承载第一子同步信号的子帧位置不同，包括：
TDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧0，FDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧5；或者，TDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧5，FDD双工模式下承载第一子同步信号的子帧位置为无线帧内的子帧0；和/或
在TDD双工模式下承载第二子同步信号的子帧位置和在FDD双工模式下承载第二子同步信号的子帧位置不同，包括：
TDD双工模式下承载第二子同步信号的子帧位置为无线帧内的子帧5，FDD双工模式下承载第二子同步信号的子帧位置为无线帧内的子帧0，且PSS的发送周期为至少两个无线帧的长度；或者，TDD双工模式下承载第二子同步信号的子帧位置为无线帧内的子帧0，FDD双工模式下承载第二子同步信 号的子帧位置为无线帧内的子帧5，且PSS的发送周期为至少两个无线帧的长度。
需要说明的是，PSS的发送周期为至少两个无线帧的长度的原因是：若PSS的发送周期为一个无线帧的长度，在TDD双工模式和FDD双工模式下，第一子同步信号和第二子同步信号不存在前后关系，总是相距5ms，终端设备检测不出来具体的双工模式。为了便于理解本发明技术方案，下面通过一个具体实例进行说明，请参阅图2，其中图2中的PSS1表示第一子同步信号，PSS2表示第二子同步信号，假设PSS的发送周期为两个无线帧的长度，当该双工模式为TDD双工模式时，承载第一子同步信号的子帧位置为无线帧内的子帧0上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，当双工模式为FDD双工模式时，承载第一子同步信号的子帧位置为无线帧内的子帧5上，承载第二子同步信号的子帧位置为无线帧内的子帧0上，终端设备若检测出第一子同步信号在第二子同步信号的前面5ms处或者第一子同步信号在第二子同步信号的后面15ms处，则确定工作模式为TDD双工模式，若检测出第一子同步信号在第二子同步信号的后面5ms处或者第一子同步信号在第二子同步信号的前面15ms处，则确定工作模式为FDD双工模式。
需要说明的是，上述指示TDD双工模式或FDD双工模式采用的是方法是通过第一子同步信号和第二子同步信号在一个无线帧内的位置顺序，在本发明的一些实施例中，还可以采用的方法是通过第一子同步信号和第二子同步信号在一个无线帧内的位置距离，例如：请参阅图3，其中图3中的PSS1表示第一子同步信号，PSS2表示第二子同步信号，当该双工模式为TDD双工模式时，承载第一子同步信号的子帧位置为无线帧内的子帧0上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，当双工模式为FDD双工模式时，承载第一子同步信号的子帧位置为无线帧内的子帧4上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，终端设备若检测出第一子同步信号和第二子同步信号相距5ms，则确定工作模式为TDD双工模式，若检测出第一子同步信号和第二子同步信号相距1ms，则确定工作模式为FDD双工模式。
需要说明的是，在实际应用中，指示信息还可以指示部署场景，由此，在本发明的一些实施例中，基站确定网络的工作模式包括：基站确定网络的工作 模式为部署场景；
基站根据确定的工作模式生成主同步信号PSS，该PSS包含多个子同步信号，其中，不同的工作模式对应不同位置的子同步信号，包括：
基站根据确定的部署场景生成主同步信号PSS，该PSS包含第一子同步信号和第二子同步信号，第一部署场景下承载第一子同步信号的子帧位置与第二部署场景下承载第一子同步信号的子帧位置不同，和/或第一部署场景下承载第二子同步信号的子帧位置与第二部署场景下承载第二子同步信号的子帧位置不同。
同理，为了保证终端设备能够区分部署场景，在第一部署场景下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置之间的距离等于在第二部署场景下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置之间的距离的条件下，需要满足在第一部署场景下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置的顺序与在第二部署场景下承载第一子同步信号的子帧位置和第二子同步信号的子帧位置的顺序不同，并且PSS的发送周期为至少两个无线帧的长度。
进一步可选的，在本发明的一些实施例中，第一部署场景下承载第一子同步信号的子帧位置与第二部署场景下承载第一子同步信号的子帧位置不同，包括：
第一部署场景下承载第一子同步信号的子帧位置为无线帧内的子帧0，第二部署场景下承载第一子同步信号的子帧位置为无线帧内的子帧5；或者第一部署场景下承载第一子同步信号的子帧位置为无线帧内的子帧5，第二部署场景下承载第二子同步信号的子帧位置为无线帧内的子帧0；和/或，
第一部署场景下承载第二子同步信号的子帧位置与第二部署场景下承载第二子同步信号的子帧位置不同，包括：
第一部署场景下承载第二子同步信号的子帧位置为无线帧内的子帧5，第二部署场景下承载第二子同步信号的子帧位置为无线帧内的子帧0；或，第一部署场景下承载第二子同步信号的子帧位置为无线帧内的子帧0，第二部署场景下承载第二子同步信号的子帧位置为无线帧内的子帧5。
需要说明的是，当部署场景为第一部署场景时，承载第一子同步信号的子 帧位置为无线帧内的子帧0上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，当部署场景为第二部署场景时，承载第一子同步信号的子帧位置为无线帧内的子帧5上，承载第二子同步信号的子帧位置为无线帧内的子帧0上，终端设备若检测出第一子同步信号位于第二子同步信号前面5ms处或者第一子同步信号位于第二子同步信号后面15ms处(假设PSS的发送周期为两个无线帧的长度)，则确定工作模式为第一部署场景，当部署场景为第一部署场景时，承载第一子同步信号的子帧位置为无线帧内的子帧5上，承载第二子同步信号的子帧位置为无线帧内的子帧0上，当部署场景为第二部署场景时，承载第一子同步信号的子帧位置为无线帧内的子帧0上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，终端设备若检测出第一子同步信号位于第二子同步信号后面5ms处或者第一子同步信号位于第二子同步信号前面15ms处，则确定工作模式为第二部署场景。
可选的，在本发明的一些实施例中，基站确定网络的工作模式包括：基站确定网络的工作模式为双工模式和部署场景；
基站根据确定的工作模式生成主同步信号PSS，该PSS包含多个子同步信号，其中，不同的工作模式对应不同位置的子同步信号，包括：
基站根据确定的双工模式和部署场景生成主同步信号PSS，该PSS包括第一子同步信号和第二子同步信号，在FDD双工模式和第一部署场景下，第一子同步信号的子帧位置为无线帧内的第一目标子帧，第二子同步信号的子帧位置为无线帧内的第二目标子帧，在FDD双工模式和第二部署场景下，第一子同步信号的子帧位置为无线帧内的第二目标子帧，第二子同步信号的子帧位置为无线帧内的第一目标子帧，第一目标子帧和所述第二目标子帧中存在至少一个子帧为非子帧0和非子帧5的子帧。
例如：请参阅图4，其中图4中的PSS1表示第一子同步信号，PSS2表示第二子同步信号，假设在FDD双工模式下，当部署场景为第一部署场景时，承载第一子同步信号的子帧位置为无线帧内的子帧4上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，当部署场景为第二部署场景时，承载第一子同步信号的子帧位置为无线帧内的子帧5上，承载第二子同步信号的子帧位置为无线帧内的子帧4上；在TDD双工模式下，当部署场景为第一部署场景 时，承载第一子同步信号的子帧位置为无线帧内的子帧0上，承载第二子同步信号的子帧位置为无线帧内的子帧5上，当部署场景为第二部署场景时，承载第一子同信号的子帧位置为无线帧内的子帧5上，承载第二子同步信号的子帧位置为无线帧内的子帧0上，终端设备若检测到第一子同步信号在第二子同步信号的前面5ms处或第一子同步信号在第二子同步信号的后面15ms处(假设PSS的发送周期为两个无线帧的长度)，则确定工作模式为TDD双工模式和第一部署场景，终端设备若检测到第一子同步信号在第二子同步信号的后面5ms处或第一子同步信号在第二子同步信号的前面15ms处，则确定工作模式为TDD双工模式和第二部署场景，终端设备若检测到第一子同步信号在第二子同步信号的前面1ms处或后面19ms处，则确定工作模式为FDD双工模式和第一部署场景，终端设备若检测到第一子同步信号在第二子同步信号的后面1ms处或前面19ms处，则确定工作模式为FDD双工模式和第二部署场景。
需要说明的是，本发明还可以通过SSS进行指示，比如指示具体的双工模式和/或部署场景，以双工模式为例：SSS为一对ZC序列，可以通过ZC序列的不同根指数来区分TDD双工模式和FDD双工模式，假设SSS的一对ZC序列为SSS1和SSS2，分别获取SSS1和SSS2的所有的根指数，组成根指数对的集合，比如SSS1有100个根指数，SSS2有100个根指数，则根指数对的集合中的根指数对有10000个，将10000个根指数对分成两部分，一部分给TDD双工模式使用，另一部分给FDD双工模式使用，终端设备通过检测SSS就能判断双工模式是TDD双工模式还是FDD双工模式。
