Description

非授权载波占用处理方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种非授权载波占用处理方法、装置及系统。
背景技术
非授权载波(免授权频谱)是指在满足政府部门(如，国家无线电管理委员会)有关规定(无线电管制)下，不需要授权就能直接使用的频谱(或载波)。例如，在我们的日常生活中，微波炉、遥控玩具飞机、无线鼠标、无线键盘、高保真无线上网(Wireless Fidelity，简称为WiFi)等都使用了非授权载波。
由于各种设备都能使用非授权载波，它们之间可能会相互干扰。如果干扰过大(如，自己的发射使得对方收到自己的功率超过-62dBm)，则可能会导致在该非授权载波上正常工作的设备停止工作。为减少或避免这种干扰，相邻设备之间最好在使用非授权载波时协商一下资源如何使用。
在有的情况下，非授权载波需要通过竞争才能使用。如果基站(包括WiFi接入点)和UE(包括WiFi站点)没有竞争到资源，则不能使用非授权载波。在一定区域内，如果只有一个基站使用非授权载波而不让其他周围相邻的基站使用，那么总的区域吞吐率可能受到影响。
长期演进(Long Term Evolution，简称为LTE)是第三代移动通信合作伙伴项目(3rd Generation Partnership Project，简称为3GPP)推出的运行在授权载波上的移动通信系统。LTE目前有Rel-8到Rel-11共4个完全向后兼容的稳定版本。
根据3GPP RAN#64次会议后关于非授权载波专题讨论会的结论(《RWS-140029Chairman Summary》和《RWS-140030_draft_report_LTE_U_workshop_140613》)，3GPP将在RAN#65次会议(2014年9月份)开始开展关于把LTE应用到非授权载波的研究项目。
因此，在相关技术中，在使用非授权载波时，相邻基站之间存在干扰，导致区域的吞吐率不高的问题。
发明内容

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种非授权载波占用处理方法，图1是根据本发明实施例的非授权载波占用处理方法一的流程图，如图1所示，该流程包括如下步骤：
步骤S102，第一基站确定占用非授权载波；
步骤S104，第一基站发送占用非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息，其中，信号/信道以及发射功率信息用于一个或多个第二基站确定自身使用非授权载波的最大发射功率。
通过上述步骤，第一基站将占用的非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息发送，用于一个或多个第二基站确定自身使用非授权载波的最大发射功率，解决了相关技术中，在使用非授权载波时，相邻基站之间存在干扰，导致区域的吞吐率不高的问题，进而达到了在使用非授权载波时相邻基站间的干扰，协调了非授权载波在各个基站之间的使用，有效地提升区域吞吐率的效果。
在协调非授权载波在各个基站之间的使用时，可以包括多个方面，下面举例说明。
例如，在第一基站发送占用非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息之后，第一基站接收到一个或多个第二基站发送的用于请求使用非授权载波的第一请求消息；第一基站将第一请求消息对应的响应消息发送给一个或多个第二基站，其中，该响应消息包括：第一基站同意或不同意一个或多个第二基站使用非授权载波；第一基站使用非授权载波的最大发射功率。
又例如，在第一基站发送占用非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息之后，第一基站接收到一个或多个第二基站发送的用于请求降低第一基站占用非授权载波时使用的发射功率的第二请求消息；第一基站依据第二请求消息降低占用非授权载波时使用的发射功率；第一基站发送降低后的发射功率。
还例如，在第一基站发送占用非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息之后，第一基站和/或第一基站通过所属用户检测到第二基站在非授权载波发送的信号/信道；第一基站和/或第一基站通过用户代理的方式向第二基站发送用于请求降低第二基站占用非授权载波时使用的发射功率的第三请求消息，其中，第三请求消息用于指示第二基站降低占用非授权载波时使用的发射功率。
其中，上述占用非授权载波的信号/信道可以包括以下至少之一：PSS/SSS、CRS、CSI-RS、PRS、MBSFN-RS、UE-RS、DM-RS、PCFICH、PHICH、PBCH、PDCCH、R-PDCCH、EPDCCH、PDSCH、SRS、PUCCH、PUSCH、PRACH。
上述发送发射功率的信号/信道可以是PSS/SSS、CRS、CSI-RS、PRS、MBSFN-RS、UE-RS、DM-RS、PCFICH、PHICH、PBCH、PDCCH、R-PDCCH、EPDCCH、PDSCH、SRS、PUCCH、PUSCH、PRACH或它们的组合。需要说明的是，上述占用非授权载波的信号/信道与上述发送发射功率的信号/信道可以相同，也可不同。例如，前面一个用高功率PSS/SSS，后面一个用PRACH。
优选地，上发射功率也可以包括多种方式，例如，可以包括以下至少之一：针对非授权载波进行管制而规定的最大发射功率、第一基站预定的最大发射功率(即自身规定的最大发射功率)、子带发射功率、物理资源块PRB级别的发射功率、子帧上的发射功率。其中，上述子带发射功率、PRB级别的发射功率、各个子帧上的发射功率可以是绝对的(例如，200mW，23dBm)也可以是相对的(例如，相对政府管制而规定发射功率。例如，管制规定最大发射功率为23dBm，而这里给出了“-3dB”这一个发射功率。则该基站的发射功率为20dBm)。
图2是根据本发明实施例的非授权载波占用处理方法二的流程图，如图2所示，该流程包括如下步骤：
步骤S202，第二基站接收到第一基站发送的占用非授权载波的信号/信道，以及占用非授权载波时使用的发射功率信息；
步骤S204，上述第二基站依据接收到的信号/信道以及发射功率信息确定自身使用非授权载波的最大发射功率。
通过上述步骤，第二基站依据接收到的信号/信道以及发射功率信息确定自身使用非授权载波的最大发射功率，解决了相关技术中，在使用非授权载波时，相邻基站之间存在干扰，导致区域的吞吐率不高的问题，进而达到了在使用非授权载波时相邻基站间的干扰，协调了非授权载波在各个基站之间的使用，有效地提升区域吞吐率的效果。
对应地，在协调非授权载波在各个基站之间的使用时，第二基站的处理也可以包括多个方面，下面举例说明。
例如，在第二基站依据接收到的信号/信道以及发射功率信息确定自身使用非授权载波的最大发射功率之后，第二基站向第一基站发送用于请求使用非授权载波的第一请求消息；第二基站接收到第一基站依据第一请求消息反馈的响应消息，其中，响应消息包括：第一基站同意或不同意一个或多个第二基站使用非授权载波；或者，第一基站使用非授权载波的最大发射功率。
又例如，在第二基站依据接收到的信号/信道以及发射功率信息确定自身使用非授权载波的最大发射功率之后，第二基站向第一基站发送用于请求降低第一基站占用非授权载波时使用的发射功率的第二请求消息；第二基站接收到第一基站依据第二请求消息降低占用非授权载波后的发射功率；第二基站依据降低后的发射功率确定自身使用非授权载波的最大发射功率。
再例如，在第二基站依据接收到的信号/信道以及发射功率信息确定自身使用非授权载波的最大发射功率之后，第二基站接收到第一基站和/或第一基站通过用户代理的方式发送的用于请求降低第二基站占用非授权载波时使用的发射功率的第三请求消息；第二基站依据第三请求消息降低第二基站占用非授权载波时使用的发射功率。
图3是根据本发明实施例的非授权载波占用处理方法三的流程图，如图3所示，该流程包括如下步骤：
步骤S302，第一基站创建预定物理资源块PRB段；
步骤S304，第一基站和/或通过第一基站所属用户检测到第二基站在预定PRB段上发送的信号/信道；
步骤S306，上述第一基站依据接收到的信号/信道对第一基站所属用户进行调度。
通过上述步骤，由第一基站创建PRB段，以及检测到第二基站占用预定的信号/信道后，对第一基站所属用户进行调度，解决了相关技术中，在使用非授权载波时，相邻基站之间存在干扰，导致区域的吞吐率不高的问题，进而达到了在使用非授权载波时相邻基站间的干扰，协调了非授权载波在各个基站之间的使用，有效地提升区域吞吐率的效果。
优选地，在第一基站创建PRB段之后，还包括：第二基站在PRB段发送预定信号/信道；第二基站依据预定信号/信道对第二基站的用户进行调度。
其中，上述预定信号/信道可以包括多种，例如，可以包括以下至少之一：以固定一种级别的高功率发送的PRB；以至少两种预定级别的功率发送的PRB。
在本实施例中还提供了一种非授权载波占用处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

当上述占用非授权载波的信号/信道在非授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个符号上发射占用非授权载波的信号/信道。当上述占用非授权载波的信号/信道可在非授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧上发射占用非授权载波的信号/信道。当上述占用非授权载波的信号/信道在授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧的第一个符号上发射占用非授权载波的信号/信道。当上述占用非授权载波的信号/信道在授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧上发射占用非授权载波的信号/信道。当上述送发射功率的信号/信道在非授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个符号上发射占用非授权载波的信号/信道。当上述送发射功率的信号/信道在非授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧上发射占用非授权载波的信号/信道。当上述送发射功率的信号/信道在授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧的第一个符号上发射占用非授权载波的信号/信道。当上述送发射功率的信号/信道在授权载波上发送时，第一个基站可以在获得非授权载波的使用权后的第一个子帧上发射占用非授权载波的信号/信道。
优选地，在第二个基站根据上述第一个基站发射的信号功率、载波检测门限以及上述发射功率来计算出自己可以发送的最大发射功率后，该第二个基站还可以执行以下操作：第二个基站请求第一个基站降低发射功率。对应地，第一个基站根据上述第二个基站的请求来降低自己的发射功率。之后，第二个基站重新测量计算第一个基站发射的信号功率以及最大发射功率。
优选地，在上述第二个基站根据上述自己可以发送的最大发射功率来服务自己的UE之后，第一个基站和/或自己服务的用户设备(需要说明的是，这面只描述了一个UE，实际可以多个)还可以向第二个基站发送要求第二个基站降低发射功率的信号/信道。例如，划分出4个专用Preamble，每个表示不同的发射功率降低要求：-3dB(相对最大功率)、-6dB、-9dB、-12dB。
上述第二个基站接收上述信号/信道。上述第二个基站根据上述信号/信道来降低自己的发射功率。需要说明的是，上述信号/信道可以是PSS/SSS、CRS、CSI-RS、PRS、 MBSFN-RS、UE-RS、DM-RS、PCFICH、PHICH、PBCH、PDCCH、R-PDCCH、EPDCCH、PDSCH、SRS、PUCCH、PUSCH、PRACH或它们的组合。

其中，上述特定的信号/信道上的信息可以包括多种，例如，上述特定的信号/信道上的信息可以包括在哪些PRB上有高功率发射(例如，该高功率只有一种功率级别)；上述特定的信号/信道上的信息可以包括在哪些PRB上有一定级别的功率发射(例如，20MHz，100个PRB，用100比特的位图，每4个比特表征一个RBG的信息，每个RBG有16个功率级别。当然，也可以是，用100比特的位图，每2个比特表征每2个PRB的信息，每2个PRB有4个功率级别)；上述基站(第一个基站和第二个基站)轮流地获得发射上述特定的信号/信道的令牌。需要说明的是，上述获得令牌的基站所发射的上述特定的信号/信道具有最高的优先级，即该站点发射的信息比其他站点更为重要。
上述方法也可作用到共享授权接入(License Shared Access，简称为LSA)载波、电视空白频段(TV White Space，简称为TVWS)上面。
通过上述处理，能够有效减少在使用非授权载波时的相邻基站之间的干扰、协调非授权载波在各个基站之间的使用、提升区域吞吐率。
