Description

一种基于非授权频段的载波测量方法和基站 技术领域
本发明涉及无线通信领域，尤其涉及一种基于非授权频段的载波测量方法和基站。
背景技术
随着通信业务量的急剧增加，3GPP授权频谱显得越来越不足以提供更高的网络容量。为了进一步提高频谱资源的利用，3GPP正讨论如何在授权频谱的帮助下使用未授权频谱，如2.4GHz和5GHz频段。这些未授权频谱目前主要是Wi-Fi，蓝牙，雷达，医疗等***在使用。载波聚合功能让将LTE部署于非授权频段变为可能。3GPP提出了LAA(Licensed Assisted Access)的概念，借助LTE授权频谱的帮助来使用未授权频谱。鉴于免授权频段上存在包括Wi-Fi、蓝牙等其它接入设备，一种用于避免雷达机制，动态频谱选择(DFS，Dynamic Frequency Selection)被提出。
LTE网络中由于有很好的正交性保证了干扰水平，基站与用户的上下行传输不用考虑周围是否有同一运营商的基站或用户在进行传输。而如果将LTE部署在非授权频段上，考虑到雷达***的最高优先级，必须执行DFS算法。而传统的LTE***中没有DFS的机制来避免干扰。为了更好的在非授权频段上工作，LTE需要DFS机制，这就是现存技术的缺陷所在。
同时，传统的DFS算法中的能量探测，都是基于RSSI的主动能量检测，基站半静态的周期性执行能量检测，这样存在的问题是：无论是否存在干扰，基站都会在某个固定时间段上执行能量检测，使得基站必须停止正常的发送和接收来执行信道检测，降低***效率。

具体实施方式
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作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1，为本发明实施例提供的一种基于非授权频段的载波测量方法的流程示意图，在本发明实施例中，所述方法包括：
S101、若小区内CQI小于预设CQI门限的用户设备的比例超过预设值，所述基站检测所述小区对应的工作载波的干扰情况。
其中，本发明实施例的基站和用户设备工作在非授权频段的小区，即小区对应的载波为，工作载波为基站所属的小区当前使用的载波。小区内的多个用 户设备会各自反馈上行信道的CQI(Channel Quality Indicator，信道质量指示，简称CQI)，基站在预设时长内接收多个用户设备反馈的CQI，并将接收到的CQI和预设CQI门限进行比较，确定CQI小于预设CQI门限的用户设备的数量，计算CQI小于预设CQI门限的用户设备的数量和小区内用户设备的数量的比例，如果计算得到的比例大于预设值，基站检测小区对应的工作载波的干扰情况，以确定工作载波是否受到强干扰，如果受到强干扰表明基站的工作载波可能需要进行切换。
S102、若所述工作载波受强干扰，所述基站向所述小区内的多个用户设备发送载波测量指示，所述载波测量指示用于指示所述多个用户设备测量各自对应的工作载波的RSSI，并向所述基站返回测量得到的RSSI。
具体的，如果工作载波受到强干扰，基站向小区内的多个用户设备发送载波测量指示，其中载波测量指示可用通过授权频段的载波或非授权频段的载波进行发送，例如：通过调度信息或RRC(Radio Resource Control，无线资源控制，简称RRC)信令进行承载。载波测量指示发送给小区内的多个用户设备，多个用户设备处于连接态的用户设备，每个用户设备接收到载波测量指示后对各自对应的工作载波进行测量，以获得工作载波的RSSI(Received Signal Strength Indicator，接收信号强度指示，简称RSSI)，并各自向基站返回测量得到的RSSI。
S103、所述基站根据所述多个用户设备反馈的RSSI确定各个用户设备是否需要进行载波切换。
具体的，基站分别对比用户设备反馈的RSSI和预设RSSI门限的关系，如果大于RSSI门限，表明对应的用户设备侧的工作载波同样受到强干扰，基站只是该用户设备进行载波切换。
实施本发明的实施例，基站在小区内CQI小于预设CQI的用户设备的比例小于预设值时，对自身测量的工作载波的干扰情况和小区内用户设备测量的工作载波的干扰情况进行评估，以确定是否进行载波切换。这样避免基站周期性的进行载波测量，由主动检测变为触发式的被动检测，减少了基站的处理开销，同时提高的载波切换评估的准确性。
参见图2，为本发明实施例提供的一种基于非授权频段载波的测量方法的另一流程示意图，在本发明实施例中，所述方法包括：
S201、基站获取小区内的多个用户设备上报的CQI。
具体的，小区对应的载波为非授权频段的载波，小区内的多个用户设备表示处于连接态的用户设备，每个用户设备在满足一定的上报条件后向基站上报CQI，例如，用户设备周期性的向基站上报CQI或用户设备在向基站传输数据之前上报CQI。其中，基站在预设时长内获取多个用户设备上报的CQI，预设时长可以根据需要进行设置，本发明不作限制。
S202、计算CQI小于预设CQI门限的用户设备的数量和所述多个用户设备的数量的比例。
其中，基站确定小区内的用户设备的数量，用户设备为连接态的用户设备，以及根据用户设备反馈的CQI判断是否小于预设CQI，统计CQI小于预设CQI门限的用户设备的数量，计算小区内CQI小于预设CQI门限的用户设备的数量和小区内的多个用户设备的数量的比例。
例如，预设CQI门限为8，基站所属的小区内有4个连接态的用户设备，基站在预设时长内获取4个用户设备反馈的CQI分别为6、5、4、10，则小区内CQI小于预设CQI门限的用户设备的数量为3个，比例为3/4＝0.75。
S203、所述比例是否大于预设值。
其中，如果S202计算得到的比例大于预设值，执行S204，如果S202计算得到的比例不大于预设值，执行S205。
例如，预设值为0.5，S202计算得到的比例为0.75，0.75＞0.5，执行S204。
S204、所述基站在预设时长内多次测量所述小区对应的工作载波的RSSI。
其中，预设时长的持续时间和在预设时长内的测量此处、时间间隔本发明不作限制，可以根据需要进行设置。
S205、不进行载波测量。
S206、所述基站将多次测量的RSSI取平均值后得到平均RSSI。
具体，对于S204多次测量得到的多个RSSI取平均值的方法本发明不作限制，可以取简单算术平均值、几何平均值和加权算术平均值等，也可以采用其他方法取平均值。
S207、所述平均RSSI是否大于预设RSSI门限值。
其中，如果S206计算得到的平均RSSI大于预设RSSI门限值，执行S208；如果S206计算得到的平均RSSI不大于预设RSSI门限值，执行S209。
S208、确定所述小区对应的工作载波受到强干扰。
其中，基站确定工作载波受到强干扰，表明业务的服务质量下降可能会影响业务的正常进行，指示小区内的用户设备进行载波测量，根据载波测量结果来进一步确认是否需要进行载波切换，以保证业务的服务质量。
S209、确定所述小区对应的工作载波未受到强干扰。
S210、基站基于非授权载波或授权载波的调度信息或RRC信令向所述小区内的多个用户设备发送载波测量指示，所述载波测量指示用户指示所述多个用户设备测量各自对应的工作载波的RSSI，并向所述基站返回测量得到的RSSI。
其中，每个用户设备在预设时长内对工作载波进行多次测量，取多次测量的平均值，向基站返回取平均值后的RSSI，具体过程可以参照基站侧测量平均RSSI的方法。
S211、反馈的RSSI是否大于所述预设RSSI门限值。
其中，基站比较每个用户设备反馈的RSSI和预设RSSI门限值的大小，如果反馈的RSSI大于预设RSSI门限值，执行S213，否则执行S212。
S212、不指示用户设备进行切换。
S213、指示用户设备进行切换。
其中，基站确定待切换的目标载波，向需要进行载波切换的用户设备发送携带目标载波的频点和带宽的载波切换制式，该用户设备接收到载波切换指示，将当前的工作载波切换到目标载波。
实施本发明的实施例，基站在小区内CQI小于预设CQI的用户设备的比例小于预设值时，对自身测量的工作载波的干扰情况和小区内用户设备测量的工作载波的干扰情况进行评估，以确定是否进行载波切换。这样避免基站周期性的进行载波测量，由主动检测变为触发式的被动检测，减少了基站的处理开销，同时提高的载波切换评估的准确性。
参见图3，为本发明实施例提供的一种通信***的交互示意图，在本发明实施例中，通信***包括基站和所属小区内的至少一个用户终端，下面就基站和一个用户设备之间的交互进行说明，交互流程如下：
S301、用户设备向基站上报CQI。其中，基站所属小区内的多个用户设备向基站上报CQI。
S302、基站统计小区内CQI小于预设门限的用户设备的数量的比例。其中，比例为小区内CQI小于预设CQI门限的用户设备的数量和小区内用户设备的数 量的比例，其中用户设备为连接态。
S303、基站确定比例大于预设值。其中比例为S302计算的比例。
S304、基站测量预设时长内工作载波的多个RSSI，并计算多个RSSI的平均值得到平均RSSI。
S305、基站确定平均RSSI大于预设RSSI门限值。其中平均RSSI为S304计算得到的。
S306、基站向用户设备发送载波测量指示。其中，用户设备为小区内为连接态的多个用户设备。
S307、用户设备在预设时长内测量多个RSSI，并取多个RSSI的平均值。其中，预设时长的持续时间、测量的RSSI的数量和测量的时间间隔本发明不作限制，可以根据需要进行设置。
S308、用户设备向基站返回平均RSSI。
S309、基站确定用户设备反馈的平均RSSI大于预设RSSI门限值。
S310、确定目标载波。
S311、基站向用户设备发送载波切换指示，以指示用户设备将当前的工作载波切换到目标载波上。
实施本发明的实施例，基站在小区内CQI小于预设CQI的用户设备的比例小于预设值时，对自身测量的工作载波的干扰情况和小区内用户设备测量的工作载波的干扰情况进行评估，以确定是否进行载波切换。这样避免基站周期性的进行载波测量，由主动检测变为触发式的被动检测，减少了基站的处理开销，同时提高的载波切换评估的准确性。
