Description

非授权载波的测量方法、系统、相关设备及计算机存储介质 技术领域
本发明涉及无线通信技术，尤其涉及一种非授权载波的测量方法、系统、相关设备及计算机存储介质。
背景技术
长期演进/高级长期演技(LTE/LTE-A，Long Term Evolution Advanced)系统是由3GPP(The 3rd Generation Partnership Project)组织制定的第四代移动通信标准。LTE支持多种带宽分配：1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz等，频谱分配更加灵活。LTE目前主要工作在授权频谱上，不同地区选择的频段也有所不同。北美网络计划使用700/800和1700/1900MHz；欧洲网络计划使用800、1800、2600MHz；亚洲网络计划使用1800MHz和2600MHz；澳洲网络计划使用1800MHz。
为了支持更宽的频带，LTE-A引入载波聚合(CA，Carrier Aggregation)，基本思想是通过将多个连续或离散的载波聚合在一起，形成更宽的频谱。通过载波聚合，LTE-A最大可支持100MHz带宽。
随着数据业务的不断增长，授权频谱资源越来越拥挤和紧张。因此一个自然的想法就是在授权载波的辅助下，使用载波聚合等方法将LTE/LTE-A系统扩展到非授权频谱资源上使用。
在非授权频谱上，除了LTE系统，还有其他WiFi、雷达(Radar)等系统的存在，为了公平性，不同地区有不同的管制要求，包括发射功率控制(TPC，Transmit Power Control)、动态频率选择(DFS，Dynamic Frequency Selection)和先听后说(LBT，Listen Before Talk)等，各系统需要采用竞争的方式来获取资源，这就需要各系统能够侦听、测量、甚至识别其他系 统或其他网络节点是否已经占用了信道资源。
WiFi系统的测量量主要是接收信号强度指示(RSSI，Received Signal Strength Indicator)，表示接收机接收到信道带宽上的宽带接收功率。在空载下，测量并看RSSI的平均值是判断干扰的最主要手段。如果发现RSSI值明显高于某一阈值，那么肯定存在反向链路干扰，也就说明信道当前被其他系统或其他网络节点占用。
LTE系统的测量主要包括信道状态信息测量和无线资源管理(RRM，Radio Resource Management)测量，信道状态信息测量主要包括公共参考信号(CRS)测量和信道状态信息测量参考信(CSI-RS)测量，而RRM测量主要包括：参考信号接收功率(RSRP，Reference Signal Receiving Power)测量、RSSI和参考信号接收质量(RSRQ，Reference Signal Receiving Quality)。RSRP定义为测量频率带宽内承载CRS的所有资源单元(RE)上接收到的线性功率的平均值。RSSI定义为测量频率带宽内CRS天线端口0所在正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号的线性总接收功率的平均值，其中测量频率带宽内有N个资源块(RB)。RSSI包含UE接收到的所有来源，包括共道服务小区、共道非服务小区、邻小区干扰及热噪声等。若高层配置RSSI在某些子帧集合中进行测量时，RSSI应使用这些子帧集合内的所有OFDM符号进行测量。而RSRQ定义为：RSRQ＝N*RSRP/RSSI。
在授权载波上，小区发送5ms周期的PSS/SSS、1ms周期的CRS，以及CSI-RS用于小区检测和RRM测量。在LAA系统中，这种短时的周期性传输会导致对临近WiFi和其他LAA节点的干扰。并且，由于非授权载波资源的占用具有不确定性，参考信号必须采用非连续发送的方式。LTE系统原有的信道状态信息测量和RRM测量方法都会存在一定的问题。
因此，需要提供一种LTE系统测量的方法，使得LTE系统的测量行为 能够适应非授权频谱上参考信号非连续传输的情况，能够正确地评估非授权载波资源的占用情况，以及向LTE系统提供可靠的信道状态信息、以及RRM测量结果。

具体实施方式
本发明实施例中，网络侧设备根据非授权载波信道的可用状态和可用性确定非授权载波的可用信道，并指示UE对所述可用信道进行测量，UE对网络侧设备指示的非授权载波的可用信道进行测量，将测量结果上报给所述网络侧设备。这里，所述网络侧设备可以是基站、中心基站或网络节点。
下面通过附图及具体实施例对本发明做进一步的详细说明。
本发明实施例实现一种非授权载波的测量方法，如图1所示，该方法包括以下几个步骤：
步骤101：网络侧设备根据非授权载波信道的可用状态和可用性确定非授权载波的可用信道；
具体的，在LTE系统中，网络侧设备如基站，根据地区管制要求对目标的非授权载波信道进行可用状态判断，判断可用状态为禁用状态，还是正常使用状态，在非授权载波上，根据地区管制要求，当有雷达信号或其他强制发送的信号到达时，非授权载波信道需要在规定时间内关闭，并在规定时间内，禁止任何系统占用所述非授权载波信道，这时的可用状态为禁用状态，其他时间的可用状态为正常使用状态。
网络侧设备在确定非授权载波信道的可用状态为正常使用状态后，根据固定的测量带宽或可变的测量带宽对非授权载波信道进行可用性测量，测量出可用信道，所述可用信道包括直接可用信道和有条件可用信道，所述可用信道可以以列表的形式形成可用信道列表；
所述根据固定的测量带宽或可变的测量带宽对非授权载波信道进行可用性测量包括：
方式一：根据固定的测量带宽对非授权载波信道进行可用性测量。
网络侧设备可预先根据数据发送需求确定测量带宽W1，例如W1可选择1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz中的一个带宽，也可以是其他合适带宽作为测量带宽。然后，按照测量带宽进行非授权载波信道的可用性测量，具体的，确定测量带宽W1后，非授权载波按照测量带宽W1可划分为N个非授权载波信道，网络侧设备可以直接对一个信道进行可用性测量，也可以依次对所有的N个信道进行可用性测量，经过测量确认为可用的信道，形成一个可用信道列表，网络侧设备可根据测量结果选择列表中的信道作为实际使用或竞争使用的信道。
方式二：根据可变的测量带宽对非授权载波信道进行可用性测量。
在下列情况下，网络侧设备可以调整测量带宽W1为W2，……，Wn，分别按照W2，……，Wn对非授权载波信道进行可用性测量，其中，W1，W2，……，Wn均为不同数值。
1)在非授权载波上按照测量带宽W1检测不到可用信道；或者可用信道的测量结果不符合要求，例如：能量检测结果大于某一阈值、或可用信道数目少于某一阈值，不利于后续进行动态信道调整。
2)网络侧设备为了获得更为全面的可用信道列表，主动按照不同测量带宽来对非授权载波信道进行可用性测量。
如图2所示，以100MHz带宽的非授权载波为例，如果按照5MHz带宽，可将所述非授权载波划分为20个信道；如果按照10MHz带宽，可将所述非授权载波划分为19个信道；如果按照20MHz带宽，可将所述非授权载波划分为17个信道。a表示的是信道占用情况，其中空白表示此处信道空闲，阴影表示此处信道忙，针对这一信道的可用性测量，如果基站按照5MHz带宽进行信道的可用性测量，会得出信道1、3、4、7、8、11、12、13、14、19为可用信道，空闲；如果按照10MHz带宽进行信道的可用性测量，会得出信道3、7、11、12、13为可用信道，空闲；如果按照20MHz带宽进行信道的可用性测量，会得出仅信道11为可用信道，空闲。
上述实例仅为本发明的一个简单示意，实际应用中，非授权载波信道按照标称信道带宽作为测量带宽进行划分，包括有效信道和保护间隔，而占用信道带宽指包含绝大部分信道能量的带宽，通常略小于标称信道带宽。非授权载波信道之间允许部分重叠，例如对于实际占用带宽为20MHz的情况，可按照22MHz标称带宽作为测量带宽来进行信道划分，相邻信道的中心频点相距5MHz。
所述进行可用性测量包括以下几种方式：
1)网络侧设备在一个或多个非授权载波信道上进行能量检测，根据检测的能量与预先设定的门限的关系，确定非授权载波信道的可用性，例如：可以在时间T内对接收信号功率进行累计平均，即RSSI测量。这里，RSSI值的大小反映了LTE系统的总体干扰水平，可以设定一定门限，如：当RSSI值小于第一门限时，认为信道空闲，为可用信道；而当RSSI值大于第三门限时，认为信道状态忙，为不可用信道。
2)网络侧设备可以对非授权载波信道的同系统干扰和异系统干扰进行测量，根据测量的干扰结果确定非授权载波信道的可用性，即：
一种方法是对非授权载波信道的干扰信号进行相干检测，如果检测到干扰信号为WiFi或雷达信号或未知信号，则认为信道当前状态忙，为不可用信道；如果检测到干扰信号为LTE信号，则可认为信道存在的干扰为同系统干扰，可以在进行干扰处理的情况下，适当使用，例如LTE系统中LAA接收机可进行同系统信号检测，然后从接收信号中减去其他同系统节点发送的信号，从而将干扰进行消除；还有一种情况是，如果仅检测到一部分同系统信号，另一部分为异系统信号，可设定一个同系统/异系统能量所占比例的门限，当同系统信号能量大于所述门限时，判定为同系统干扰，否则判定为异系统干扰。
另一种方法是：LTE系统可以按周期或按需求统一静默，即不发送任何LTE信号，这时网络侧设备对非授权载波信道测量得到的干扰信号则完全为异系统干扰，认为非授权载波信道为不可用信道；其中，所述LTE系统可以按周期或按需求统一静默可以包括以下任一种方式：
A、某一非授权载波信道上的所有LAA节点按照静默图样进行静默；
B、由于相距较远的LAA节点之间可认为几乎没有干扰，可将某一非授权载波信道上的LAA节点按照地理位置进行分簇，一个簇内的LAA节点按照同一个静默图样进行静默；
所述静默图样是指约定LAA节点允许发送和静默的图样，其中静默的时间粒度可以是连续的几个帧/子帧/OFDM符号，也可以是离散的帧/子帧/OFDM符号，这里，LAA节点的静默图样可以周期性重复，也可以一次性配置使用。
所述网络侧设备在检测到非授权载波信道存在的干扰为同系统干扰后，还可以对非授权载波信道上的不同运营商设备部署的LAA节点的干扰信号进行区分，即：
A、可以检测识别接收到的同系统干扰信号，解析同系统干扰信号里携带的运营商信息、小区信息，如果识别出的运营商信息或小区信息属于其他运营商，则判断为同系统异运营商干扰，如果识别出的运营商信息或小区信息属于自身运营商，则判断为同系统同运营商干扰；
B、协调不同运营商的LAA节点采用的静默图样，例如：将运营商A和运营商B采用的静默图样中的一部分重合，用于检测异系统干扰，另一部分不重合，用于检测同系统异运营商干扰。
进一步的，若异运营商LAA节点之间不能保证同步，还可以通过开放移动联盟(OMA)配置、空口或者小区间回程线路(backhaul)接口协调静默图样。
上述方式1)和方式2)可以结合使用，网络侧设备预先设置第一门限、第二门限、第三门限，在一个或多个非授权载波信道上进行能量检测，当检测到的能量小于第一门限时，认为非授权载波信道为直接可用信道；当检测到的能量大于第一门限，小于第二门限时，对非授权载波信道的同系统干扰和异系统干扰进行测量，根据测量的干扰结果确定非授权载波信道的可用性；当检测到的能量大于第三门限时，认为非授权载波信道为不可用信道。例如：可以使用RSSI门限和异系统/同系统干扰相结合的方式进行可用性测量，包括：
(1)当RSSI值小于第一门限时，即认为信道空闲，非授权载波信道为直接可用信道。
(2)当RSSI值大于第一门限，小于第二门限时，对非授权载波信道进行同系统/异系统干扰测量：
例如可采用对干扰信号相干接收的方法或LTE系统静默的方法来进行同系统/异系统干扰测量，如果干扰来自异系统，则认为信道当前状态忙，非授权载波信道为不可用信道；如果干扰来自同系统，则认为非授权载波信道为有条件可用信道。
3)当RSSI值大于第三门限时，认为信道当前状态忙，非授权载波信道为不可用信道。
例如：上述的第一门限可以为-80dBm～-90dBm之间，第二门限可以为-50dBm～-60dBm之间，第三门限可以为-20dBm～-30dBm之间。
对于上述直接可用信道和有条件可用信道可以统一为可用信道，可以将可用信道和不可用信道通过不同的标记进行标示，例如用0、1来标记可用信道和不可用信道，也可以将直接可用信道、有条件可用信道和不可用信道均通过不同的标记进行标示，例如使用0、1、2来标记直接可用信道、有条件可用信道和不可用信道。
本步骤对非授权载波的可用信道的确定可以由需要使用信道的基站进行，也可以由某一个中心基站或网络节点进行，再将可用信道通知给其他基站或网络节点。
步骤102：网络侧设备指示UE对所述可用信道进行测量；
这里，网络侧设备可以在对所述可用信道的占用期向UE发送测量参考信号，以指示UE根据所述测量参考信号对所述可用信道进行测量；
具体的，网络侧设备对确定的可用信道采用直接获得或竞争获得的方式获得使用权，在获得使用权之后，进入对所述可用信道的占用期，网络 侧设备可随辅小区(Scell)激活信令一起或单独发送下行控制信号，将测量参考信号发送给UE，以及调度UE进行CSI测量和RRM测量上报，在UE根据测量参考信号上报测量结果之前，网络侧设备按照保守的发送方式、低级别的调制编码方式，进行数据发送，例如采用分集发送、BPSK调制方式等。在收到UE上报的测量结果后，网络侧设备依据UE的测量结果，选择相应的发送方式、调制编码级别进行数据发送。
在步骤101与步骤102之间，网络侧设备在确定出非授权载波的可用信道后，如果地区管制允许发送短控制信令，网络侧设备可在对所述可用信道的非占用期，即在Scell获得所述可用信道的使用权之前，发送短控制信令形式的测量参考信号给UE，所述短控制信令形式的测量参考信号包括：PSS/SSS、CRS、CSI-RS等，这种短控制信令形式的测量参考信号称为非授权频谱上的发现信号(UCDS，Unlicensed Carrier Discovery Signal)。UE可利用这些短控制信令形式的测量参考信号获取同步参数、进行CSI测量和RRM测量(包括RSRP和RSRQ测量)，这样网络侧设备在获得所述可用信道的使用权后，可以快速地利用相应的CSI测量进行快速、准确的数据调度发送。
需要说明的是，本发明实施例中提及的短控制信令不单单指欧洲电信标准化协会(ETSI)规定中的短控制信令(SCS，Short Control Signalling)，而泛指在非占用期的特殊时长内发送的短时的信号、信道。在短控制信令时长内发送信号、信道，LAA接入点不需要执行空闲信道评估(CCA)和LBT功能。短控制信令发送时长需要满足一定的管制要求，否则就违背了非授权频段不同系统和设备友好共存的原则。有些地区和国家对于短控制信令可能有另外的名称和定义，这里统称为短控制信令。还有些地区和国家可能没有定义短控制信令，针对这些地区和国家可以定义短控制信令以及类似规则要求(例如对发送时长的要求，在固定时长的观察期内发送时 长不得大于设定比例)来进行非占用期的信号发送。
网络侧设备通过主小区(Pcell)配置Scell的UCDS的发送，并通过Pcell将UCDS的发送配置指示给UE，UCDS的发送配置可以包括以下信息中的一个或多个：载波中心频率、信道带宽、PSS/SSS序列信息、CRS序列信息、CSI-RS序列信息、CSI-RS配置等。
即使地区管制允许发送短控制信令，网络侧设备通过可用信道发送短控制信令形式的测量参考信号的过程中所述可用信道仍然有可能被其他系统占用，例如雷达系统，从而短控制信令形式的测量参考信号的发送不得不被中断，网络侧设备可以不间断的对所述可用信道的可用状态进行判断，通过所述可用信道的可用状态来隐式地通知UE短控制信令形式的测量参考信号的发送情况，也可以通过Pcell向UE发送下行控制信号，显式地通知UE短控制信令形式的测量参考信号的发送情况。
隐式通知方式为：
通过所述可用信道的可用状态为禁用状态，通知UE在当前时刻不发送短控制信令形式的测量参考信号；通过所述可用信道的可用状态为正常使用状态，通知UE在当前时刻正常发送短控制信令形式的测量参考信号。
显式通知方式为：
网络侧设备可以通过Pcell发送下行控制信号通知UE短控制信令形式的测量参考信号的发送情况，可以采取的方式包括：
1)在短控制信令形式的测量参考信号发送周期的整数倍时间点，通知下一个时间段内是否发送短控制信令形式的测量参考信号，例如：短控制信令形式的测量参考信号的发送周期为T，可以每隔N*T时间发送一个通知信号，指示下一个N*T时间段内是否发送短控制信令形式的测量参考信号。
2)在短控制信令形式的测量参考信号发送周期的整数倍时间点，检查 短控制信令形式的测量参考信号在下一个时间段内的发送情况是否会发生变化，如果在下一个时间段内，发送情况发生变化，例如：从不允许发送变为允许发送，或者从允许发送变为不允许发送，则指示UE短控制信令形式的测量参考信号的发送情况发生变化，否则，不进行指示。
3)默认短控制信令形式的测量参考信号为允许发送，仅在不允许发送的情况下，通知UE短控制信令形式的测量参考信号停发，可以约定每次停发的持续时间Tstop，或者随停发通知一起通知准确的停发时间。
本实施例的方法还包括：UE根据网络侧设备下发的测量参考信号对非授权载波的可用信道进行测量，将测量结果进行平滑后上报给所述网络侧设备；
由于非授权载波上，测量参考信号无法进行连续发送，甚至无法进行持续时间较长的发送，因此UE测量的统计时间可按照一次非授权载波的可用信道的占用时间或者更短的时间来进行统计，当次对所述可用信道的占用期的测量结果在当次所述可用信道的占用时间内可利用授权载波或非授权载波上报，例如：UE上报RRM测量结果的周期为T_report，初次上报时间为T0，占用期为T_occupy，则UE可在下述时间点上进行M次上报：
T0+T_report，T0+2*T_report，……，T0+M*T_report，
其中T0+M*T_report<＝T_occupy<＝T0+(M+1)*T_report；
如果T_occupy<T_report，那么UE在对所述可用信道的占用期内，没能进行一次成功的上报，则UE可对所述可用信道的占用期内的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波或其他非授权载波上报测量结果。
对于占用期内最后一次未完成的测量，UE可对占用期内剩余的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波上报测量结果。
如果UE只有在对所述可用信道的占用期对所述可用信道进行测量，那么只有占用期的测量结果，这些占用期的测量结果可以进行平滑操作。
如果UE在对所述可用信道的占用期与非占用期都对所述可用信道进行测量，那么对于占用期测量结果与非占用期的测量结果，可以按如下任一方式进行平滑：
1)占用期的测量结果单独进行平滑，得到一个长期的占用期的测量结果；非占用期的测量结果单独平滑，得到一个长期的非占用期测量结果；
这里，所述占用期的测量结果单独进行平滑，例如：当前统计的占用期历史测量结果是R_pre，当次占用期的测量结果为R_occupy，平滑加权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_occupy；
注意：对于第一个测量结果，R_pre＝R_occupy；
所述非占用期的测量结果单独进行平滑例如：当前统计的非占用期历史测量结果是R_pre，当次非占用期的测量结果为R_non_occupy，平滑加权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_non_occupy。
注意对于第一个测量结果，R_pre＝R_non_occupy。
2)通过不同的加权因子对占用期的测量结果与非占用期的测量结果一起平滑，具体的，可以增加占用期的测量结果与非占用期的测量结果的加权因子，以调节占用期测量结果所占的权重和非占用期的测量结果所占的权重。
例如：当前统计的历史测量结果是R_pre，若当次测量结果为占用期测量结果R_occupy，占用期加权因子为a，则此次测量结果可按照下式进行平滑：R_next＝(1-a)*R_pre+a*R_occupy；若当次测量结果为非占用期测量结果R_non_occupy，非占用期加权因子为b，则此次测量结果可按照下 式进行平滑：R_next＝(1-b)*R_pre+b*R_non_occupy。
注意：对于第一个测量结果，若第一个测量结果为占用期测量结果R_occupy，则R_pre＝R_occupy；若第一个测量结果为非占用期测量结果R_non_occupy，则R_pre＝R_non_occupy。
此外，网络侧设备在对非授权载波的可用信道的占用期内，仍然继续进行所有非授权载波信道的可用状态和可用性检测，维护可用信道列表，其中，在进行所有非授权载波信道的可用性检测时，可以根据固定的测量带宽或可变的测量带宽对所有非授权载波信道进行可用性测量，维护可用信道列表。
网络侧设备还可以根据UE上报的测量结果确定当前处于占用期的非授权载波信道的信道状态发生恶化时，例如当前CSI测量结果反应的SINR小于某一门限值和/或RSRQ值小于某一门限值，或与其他信道RSRQ测量值的差值大于某一阈值，网络侧设备可通过可用信道列表快速地切换到其他信道。
对于非授权载波上支持上行发送的情况，网络侧设备也可以对UE发送的非连续发送的上行测量信号进行测量，例如：对探测参考信号(SRS)进行测量。
基于上述方法，本发明实施例还提供一种非授权载波的测量方法，如图3所示，该方法包括以下几个步骤：
步骤301：UE对网络侧设备指示的非授权载波的可用信道进行测量；
具体的，UE接收网络侧设备不连续下发的测量参考信号，根据所述测量参考信号对非授权载波的可用信道进行测量。
步骤302：UE将测量结果进行平滑后上报给所述网络侧设备；
具体的，UE按照一次非授权载波的可用信道的占用时间或者指定的时间来进行测量结果的统计，当次对所述可用信道的占用期的测量结果在当 次所述可用信道的占用时间内利用授权载波或非授权载波上报，例如：UE上报RRM测量结果的周期为T_report，初次上报时间为T0，占用期为T_occupy，则UE可在下述时间点上进行M次上报：
T0+T_report，T0+2*T_report，……，T0+M*T_report，
其中T0+M*T_report<＝T_occupy<＝T0+(M+1)*T_report；
如果T_occupy<T_report，那么UE在对所述可用信道的占用期内，没能进行一次成功的上报，则UE可对所述可用信道的占用期内的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波或其他非授权载波上报测量结果。
对于占用期内最后一次未完成的测量，UE可对占用期内剩余的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波上报测量结果。
如果UE只有在对所述可用信道的占用期对所述可用信道进行测量，那么只有占用期的测量结果，这些占用期的测量结果可以进行平滑操作。
如果UE在对所述可用信道的占用期与非占用期都进行测量，那么对于占用期测量结果与非占用期的测量结果，可以按如下任一方式进行平滑：
1)占用期的测量结果单独进行平滑，得到一个长期的占用期的测量结果；非占用期的测量结果单独平滑，得到一个长期的非占用期测量结果；
这里，所述占用期的测量结果单独进行平滑，例如：当前统计的占用期历史测量结果是R_pre，当次占用期的测量结果为R_occupy，平滑加权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_occupy；
注意：对于第一个测量结果，R_pre＝R_occupy；
所述非占用期的测量结果单独进行平滑例如：当前统计的非占用期历史测量结果是R_pre，当次非占用期的测量结果为R_non_occupy，平滑加 权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_non_occupy。
注意对于第一个测量结果，R_pre＝R_non_occupy。
2)通过不同的加权因子对占用期的测量结果与非占用期的测量结果一起平滑，具体的，可以增加占用期的测量结果与非占用期的测量结果的加权因子，以调节占用期测量结果所占的权重和非占用期的测量结果所占的权重。
例如：当前统计的历史测量结果是R_pre，若当次测量结果为占用期测量结果R_occupy，占用期加权因子为a，则此次测量结果可按照下式进行平滑：R_next＝(1-a)*R_pre+a*R_occupy；若当次测量结果为非占用期测量结果R_non_occupy，非占用期加权因子为b，则此次测量结果可按照下式进行平滑：R_next＝(1-b)*R_pre+b*R_non_occupy。
注意：对于第一个测量结果，若第一个测量结果为占用期测量结果R_occupy，则R_pre＝R_occupy；若第一个测量结果为非占用期测量结果R_non_occupy，则R_pre＝R_non_occupy。
基于上述方法，本发明实施例还提供一种非授权载波的测量方法，如图4所示，该方法包括以下几个步骤：
步骤401：网络侧设备根据非授权载波信道的可用状态和可用性确定非授权载波的可用信道；
步骤402：网络侧设备指示用户设备UE对所述可用信道进行测量；

为了实现上述方法本发明还提供一种网络侧设备，如图5所示，该网 络侧设备包括：可用信道确定模块51、信号下发模块52；其中，
可用信道确定模块51，可以由处理器实现，配置为根据非授权载波信道的可用状态和可用性确定非授权载波的可用信道；
信号下发模块52，可以由通信芯片实现，配置为指示UE对所述可用信道进行测量；
所述信号下发模块52，具体配置为在对所述可用信道的占用期向UE发送测量参考信号；
所述可用信道确定模块51，具体配置为根据地区管制要求对目标的非授权载波信道进行可用状态判断，在确定非授权载波信道的可用状态为正常使用状态后，根据固定的测量带宽或可变的测量带宽对非授权载波信道进行可用性测量，测量出可用信道，所述可用信道包括直接可用信道和有条件可用信道，所述可用信道可以以列表的形式形成可用信道列表；
所述根据固定的测量带宽或可变的测量带宽对非授权载波信道进行可用性测量包括：
方式一：根据固定的测量带宽对非授权载波信道进行可用性测量。
可预先根据数据发送需求确定测量带宽W1，例如W1可选择1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz中的一个带宽，也可以是其他合适带宽作为测量带宽，然后，按照测量带宽进行非授权载波信道的可用性测量。
方式二：根据可变的测量带宽对非授权载波信道进行可用性测量。
可调整测量带宽W1为W2，……，Wn，分别按照W2，……，Wn对非授权载波信道进行可用性测量，其中，W1，W2，……，Wn均为不同数值。
所述进行可用性测量包括以下几种方式：
1)在一个或多个非授权载波信道上进行能量检测，根据检测的能量与 预先设定的门限的关系，确定非授权载波信道的可用性，例如：可以在时间T内对接收信号功率进行累计平均，即RSSI测量。这里，RSSI值的大小反映了LTE系统的总体干扰水平，可以设定一定门限，如：当RSSI值小于第一门限时，认为信道空闲，为可用信道；而当RSSI值大于第三门限时，认为信道状态忙，为不可用信道。
2)可以对非授权载波信道的同系统干扰和异系统干扰进行测量，根据测量的干扰结果确定非授权载波信道的可用性，即：
一种方法是对非授权载波信道的干扰信号进行相干检测，如果检测到干扰信号为WiFi或雷达信号或未知信号，则认为信道当前状态忙，为不可用信道；如果检测到干扰信号为LTE信号，则可认为信道存在的干扰为同系统干扰，可以在进行干扰处理的情况下，适当使用，例如LTE系统中LAA接收机可进行同系统信号检测，然后从接收信号中减去其他同系统节点发送的信号，从而将干扰进行消除；还有一种情况是，如果仅检测到部分同系统信号，另一部分为异系统信号，可设定一个同系统/异系统能量所占比例的门限，当同系统信号能量大于所述门限时，判定为同系统干扰，否则判定为异系统干扰。
另一种方法是：LTE系统可以按周期或按需求统一静默，即不发送任何LTE信号，这时对非授权载波信道测量得到的干扰信号则完全为异系统干扰。
上述方式1)和方式2)可以结合使用，网络侧设备预先设置第一门限、第二门限、第三门限，在一个或多个非授权载波信道上进行能量检测，当检测到的能量小于第一门限时，认为非授权载波信道为直接可用信道；当检测到的能量大于第一门限，小于第二门限时，对非授权载波信道的同系统干扰和异系统干扰进行测量，根据测量的干扰结果确定非授权载波信道的可用性；当检测到的能量大于第三门限时，认为非授权载波信道为不可 用信道；例如可以使用RSSI门限和异系统/同系统干扰相结合的方式进行可用性测量，包括：
(1)当RSSI值小于第一门限时，即认为信道空闲，非授权载波信道为直接可用信道。
(2)当RSSI值大于第一门限，小于第二门限时，对非授权载波信道进行同系统/异系统干扰测量：
例如可采用对干扰信号相干接收的方法或LTE系统静默的方法来进行同系统/异系统干扰测量，如果干扰来自异系统，则认为信道当前状态忙，非授权载波信道为不可用信道；如果干扰来自同系统，则认为非授权载波信道为有条件可用信道。
3)当RSSI值大于第三门限时，认为信道当前状态忙，非授权载波信道为不可用信道。
其中，所述第一门限小于所述第二门限；所述第二门限小于所述第三门限。
对于上述直接可用信道和有条件可用信道可以统一为可用信道，可以将可用信道和不可用信道通过不同的标记进行标示，例如用0、1来标记可用信道和不可用信道，也可以将直接可用信道、有条件可用信道和不可用信道均通过不同的标记进行标示，例如使用0、1、2来标记直接可用信道、有条件可用信道和不可用信道。
所述信号下发模块52，具体配置为对确定的可用信道采用直接获得或竞争获得的方式获得使用权，在获得使用权之后，进入对所述可用信道的占用期，可随Scell激活信令一起或单独发送下行控制信号，在所述下行控制信号中携带测量参考信号将测量参考信号发送给UE，以及调度UE进行CSI测量和RRM测量上报，在UE根据测量参考信号上报测量结果之前，按照保守的发送方式、低级别的调制编码方式，进行数据发送，例如采用 分集发送、BPSK调制方式等，在收到UE上报的测量结果后，依据UE的测量结果，选择相应的发送方式、调制编码级别进行数据发送。
所述信号下发模块52，还配置为在地区管制允许发送短控制信令时，在对所述可用信道的非占用期，即在Scell获得所述可用信道的使用权之前，发送短控制信令形式的测量参考信号给UE，所述短控制信令形式的测量参考信号包括：PSS/SSS、CRS、CSI-RS等，这种短控制信令形式的测量参考信号称为UCDS。
所述信号下发模块52，还配置为通过Pcell配置Scell的UCDS的发送，并通过Pcell将UCDS的发送配置指示给UE，UCDS的发送配置可以包括以下信息中的一个或多个：载波中心频率、信道带宽、PSS/SSS序列信息、CRS序列信息、CSI-RS序列信息、CSI-RS配置等。
即使地区管制允许发送短控制信令，通过可用信道发送短控制信令形式的测量参考信号的过程中所述可用信道仍然有可能被其他系统占用，例如雷达系统，从而短控制信令形式的测量参考信号的发送不得不被中断，所述信号下发模块52，还配置为通过所述可用信道的可用状态隐式地通知UE短控制信令形式的测量参考信号的发送情况，或者，通过Pcell向UE发送下行控制信号，显式地通知UE短控制信令形式的测量参考信号的发送情况。
隐式通知方式为：
通过所述可用信道的可用状态为禁用状态，通知UE在当前时刻不发送短控制信令形式的测量参考信号；通过所述可用信道的可用状态为正常使用状态，通知UE在当前时刻正常发送短控制信令形式的测量参考信号。
显式通知方式为：
网络侧设备可以通过Pcell发送下行控制信号通知UE短控制信令形式的测量参考信号的发送情况，可以采取的方式包括：
1)在短控制信令形式的测量参考信号发送周期的整数倍时间点，通知下一个时间段内是否发送短控制信令形式的测量参考信号，例如：短控制信令形式的测量参考信号的发送周期为T，可以每隔N*T时间发送一个通知信号，指示下一个N*T时间段内是否发送短控制信令形式的测量参考信号。
2)在短控制信令形式的测量参考信号发送周期的整数倍时间点，检查短控制信令形式的测量参考信号在下一个时间段内的发送情况是否会发生变化，如果在下一个时间段内，发送情况发生变化，例如：从不允许发送变为允许发送，或者从允许发送变为不允许发送，则指示UE短控制信令形式的测量参考信号的发送情况发生变化，否则，不进行指示。
3)默认短控制信令形式的测量参考信号为允许发送，仅在不允许发送的情况下，通知UE短控制信令形式的测量参考信号停发，可以约定每次停发的持续时间Tstop，或者随停发通知一起通知准确的停发时间。
所述可用信道确定模块51，还配置为在对非授权载波的可用信道的占用期内，仍然继续进行所有非授权载波信道的可用状态和可用性检测，维护可用信道列表，在根据UE上报的测量结果确定当前处于占用期的非授权载波信道的信道状态发生恶化时，通过可用信道列表切换到其他信道。
该网络侧设备还包括上行测量模块53，配置为对于非授权载波上支持上行发送的情况，对UE发送的非连续发送的上行测量信号进行测量。
实际应用时，所述上行测量模块53可以由处理器结合通信芯片实现。

所述上报模块62，具体配置为按照一次非授权载波的可用信道的占用时间或者指定的时间来进行测量结果的统计，当次对所述可用信道的占用期的测量结果在当次所述可用信道的占用时间内利用授权载波或非授权载波上报；
所述上报模块62，还配置为在对所述可用信道的占用期内，没能进行一次成功的上报，则通知测量模块61对所述可用信道的占用期内的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波或其他非授权载波上报测量结果；
所述上报模块62，还配置为对于占用期内最后一次未完成的测量，通知测量模块61对占用期内剩余的全部测量参考信号进行测量，在当次占用时间结束后，通过授权载波上报测量结果；
所述上报模块62，具体配置为在测量模块61对所述可用信道的占用期与非占用期都进行测量后，对于占用期测量结果与非占用期的测量结果，可以按如下任一方式进行平滑：
1)占用期的测量结果单独进行平滑，得到一个长期的占用期的测量结果；非占用期的测量结果单独平滑，得到一个长期的非占用期测量结果；
这里，所述占用期的测量结果单独进行平滑，例如：当前统计的占用期历史测量结果是R_pre，当次占用期的测量结果为R_occupy，平滑加权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_occupy；
注意：对于第一个测量结果，R_pre＝R_occupy；
所述非占用期的测量结果单独进行平滑例如：当前统计的非占用期历 史测量结果是R_pre，当次非占用期的测量结果为R_non_occupy，平滑加权因子为a，则此次测量结果可按照下式进行平滑：R_pre＝(1-a)*R_pre+a*R_non_occupy。
注意对于第一个测量结果，R_pre＝R_non_occupy。
2)通过不同的加权因子对占用期的测量结果与非占用期的测量结果一起平滑，具体的，可以增加占用期的测量结果与非占用期的测量结果的加权因子，以调节占用期测量结果所占的权重和非占用期的测量结果所占的权重。
例如：当前统计的历史测量结果是R_pre，若当次测量结果为占用期测量结果R_occupy，占用期加权因子为a，则此次测量结果可按照下式进行平滑：R_next＝(1-a)*R_pre+a*R_occupy；若当次测量结果为非占用期测量结果R_non_occupy，非占用期加权因子为b，则此次测量结果可按照下式进行平滑：R_next＝(1-b)*R_pre+b*R_non_occupy。
注意：对于第一个测量结果，若第一个测量结果为占用期测量结果R_occupy，则R_pre＝R_occupy；若第一个测量结果为非占用期测量结果R_non_occupy，则R_pre＝R_non_occupy。
