Description

一种频率共享方法、用户设备和基站 技术领域
本文涉及通信领域，尤其涉及一种频率共享方法、用户设备和基站。
背景技术
根据国际电信同盟(ITU，International Telecommunications Union)的预测，随着用户移动通信需求的不断攀升，到2020年，移动通信业务有可能出现超过500倍，甚至到达1000倍的增长，因此无线通讯业内正在探讨各种可能的技术，以扩容网络能力，增强网络覆盖，从而满足移动业务爆发式增长的态势。其中一种可能的方向为让多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术之间共享使用相同的频率资源，从而打破传统蜂窝无线通信技术在授权频带(licensed spectrum/licensed band)上通过完全独占一个授权频率或者在一定时间、一定区域内独占一个授权频率的方式，以提高频率利用率，扩容网络能力，增强网络覆盖。
但是多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术很有可能会同一时间在相同的频率上发起数据传输，从而导致多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术之间发生相互的干扰或者冲突的情况。
此外，当可共享使用的频率资源上已经有在用的非蜂窝无线通信系统部署的时候，如无线本地局域网(WLAN，Wireless Local Area Network)、无线个域网(WPAN，Wireless Personal Area Network)、全球微波接入互操作性系统(WiMax，World Interoperability for Microwave Access)等，将蜂窝无线通信技术部署到这些可共享使用的频率资源上也会造成对这些在用的非蜂窝无线通信系统的干扰。
因此，有必要寻求技术方案解决可共享使用的频率资源上的多种无线通信技术(包括蜂窝无线通信技术之间以及蜂窝无线通信技术与非蜂窝无线通信技术之间)或者多个运营商部署的同种无线通信技术之间的干扰的问题。

条件三，虽然在第二小区的公共信道上接收到其他UE或基站发送的信道占用信令但所述信道占用信令指示的信道占用时间已过。
对于本发明实施例来说，UE也可以只包括上述移动通信模块，此时如UE的移动通信模块通过检测确定满足上述条件一和条件二或确定满足上述条件一和条件三，UE即可确定第二载波可用，并通过移动通信模块在第二载波上发送移动通信制式的信道占用信令。
步骤130，UE激活第二小区，根据第二基站的调度进行数据传输。
上述流程实现了对信道占用的告之。所述UE邻近的WLAN设备接收到所述WLAN制式的信道占用信令后，在所述信道占用信令指示的信道占用时间内不在第二载波上发起数据传输；同时，所述UE邻近的其他基站在接收到所述UE发送的移动通信制式的信道占用信令后，在所述信道占用信令指示的信道占用时间内不在第二载波上发起与本基站下UE的数据传输。从而可以避免多个运营商部署的同种无线通信技术之间，和/或共享使用的频率上多种无线通信技术之间的干扰。
本实施例方法又可以通过但不局限于以下两种实现方式。
方式一：
本方式下，UE对第二小区配置完成后，需要在第二小区的公共信道上接收第二基站发送的信道占用请求，如接收到所述信道占用请求且确定第二载波可用后，再在第二载波上发送信道占用信令；发送所述信道占用信令后，即激活所述第二小区。对第二载波上信号的检测，可以在第二小区配置完成后开始，也可以在收到所述信道占用请求后开始。
本方式下，如UE开启了WLAN功能，UE在第二载波上发送信道占用信令，包括：所述UE以时分复用的方式，在第二载波上发送WLAN制式的信道占用信令，在第二小区的公共信道上发送移动通信制式的信道占用响应。
可选地，所述第二基站发送的信道占用请求携带第二小区的标识信息和第一信道占用时长的信息，所述UE发送的信道占用响应携带所述UE的标识信息和第二信道占用时长的信息，所述UE发送的WLAN制式的信道占用信令携带第五信道占用时长的信息。信道占用时长由所在消息的发送方确定。
可选地，第二信道占用时长T2＝T1-t1-t2-t3-t4，其中，T1为第一信道占用时长，t1为所述信道占用请求在空中接口的传输时间，t2为所述UE接收和处理所述信道占用请求的时间，t3为所述UE发送所述信道占用响应的处理时间，t4为所述信道占用响应在空中接口的传输时间。
可选地，所述第五信道占用时长T5＝T1-t1-t2-t5-t6-t7，T1为第一信道占用时长，t1为所述信道占用请求在空中接口的传输时间，t2为所述UE接收和处理所述信道占用请求的时间，t5为所述UE发送所述WLAN制式的信道占用信令的处理时间，t6为竞争使用第二载波的退避时间，t7为所述WLAN制式的信道占用信令在空中接口的传输时间。
上述信道占用时长的计算可以有其他等同的替代方式。以第二基站发送的所述信道占用请求为例，如果第二基站计算第一信道占用时长时，已考虑所述信道占用请求在空中接口的传输时间，则所述UE按照T2＝T1-t2-t3-t4计算第二信道占用时长，按照T5＝T1-t2-t5-t6-t7计算第五信道占用时长，而其他基站接收到该信道占用请求，将以接收到所述信道占用请求的时刻加上第一信道占用时长作为其指示的信道占用时间。如果第二基站计算第一信道占用时长时，不考虑所述信道占用请求在空中接口的传输时间，则UE按照上述实施例的公式来计算第二信道占用时长和第五信道占用时长，而其他基站接收到该信道占用请求，将以接收到所述信道占用请求的时刻加上第一信道占用时长、再减去所述信道占用请求在空中接口的传输时间，得到的值作为其指示的信道占用时间。以此类推，如果UE计算第二信道占用时长时不考虑所述信道占用响应在空中接口的传输时间，则关于T2的计算公式中不需要减去t4，等等。
方式二：
该方式下，基站不向UE发送信道占用响应，UE对第二小区配置完成后，如通过检测确定第二载波可用，即可以在第二载波上发送信道占用信令，包括：以时分复用的方式，在第二载波上发送WLAN制式的信道占用信令，在第二小区的公共信道上发送移动通信制式的信道占用请求。所述UE可以在发送所述信道占用请求后即激活第二小区；所述UE也可以在发送 所述信道占用请求后，在第二小区的公共信道上接收第二基站发送的信道占用响应，如收到，再激活第二小区，所述信道占用响应中携带第二小区的标识信息和第四信道占用时长的信息。
可选地，UE发送的移动通信制式的信道占用请求携带所述UE的标识信息和第三信道占用时长的信息，第二基站发送的信道占用响应中携带第二小区的标识信息和第四信道占用时长的信息，UE发送的WLAN制式的信道占用信令携带第五信道占用时长的信息。
可选地，所述UE接收到的第二小区的配置信息中包含第一基站期望在第二小区上传输的数据流量或第一基站期望所述UE在第二小区上激活的时间长度；所述UE根据所述数据流量或时间长度确定第三信道占用时长。
可选地，所述第四信道占用时长T4＝T3-t1’-t2’-t3’-t4’，其中，T3为第三信道占用时长，t1’为所述信道占用请求在空中接口的传输时间，t2’为第二基站接收和处理所述信道占用请求的时间，t3’为第二基站发送所述信道占用响应的处理时间，t4’为所述信道占用响应在空中接口的传输时间。与方式一中第二信道占用时长类似的，第四信道占用时长也有其他的等同计算方式，这里不再赘述。
可选地，所述第五信道占用时长T5＝T3，其中，T3为第三信道占用时长。
相应地，本实施例的UE如图2所示，包括在多载波场景下与基站通信的移动通信模块10，其中：

为了避免干扰，所述UE的邻近基站和第二基站的邻近基站收到所述UE或第二基站发送的信道占用信令后，在所述信道占用信令指示的信道占用时间内，不在第二载波上发起与本基站下UE的通信。
本实施例方法又可以通过但不局限于以下两种实现方式。
方式一：

图中还示出了可选的信道占用单元603。
对应于上述方法的两种实现方式，基站上述模块还要实现以下特定功 能。
对应于方式一
第二载波处理模块60还包括信道占用单元603；其中：
所述信道占用单元603，设置为：在有UE的第二小区处于非激活状态时，如检测到邻近设备在第二载波上发射的信号的信号强度未超过预设值，则在第二小区的公共信道上发送信道占用请求，携带第二小区的标识信息和第一信道占用时长的信息；

在发送的情况下：

实施例三
本实施例对应于实施例一和实施例二的方式一，从收发两个方面描述频率共享的方案，
本实施例提供一种频率共享方法，适用于多载波场景，UE在使用第一载波的第一小区上与第一基站建立了RRC连接，如图5所示，所述方法包括：
步骤310、第一基站为UE配置第二基站下的第二小区，所述第二小区使用的第二载波为可共享使用的载波；
第一基站通过第一小区与UE的无线接入链路为UE配置第二小区。第一基站为UE配置了第二小区之后，UE和第二基站将第二小区设置为非激活状态，第二基站和UE之间不在第二小区上传输数据，但第二基站可以通过第二小区的公共信道在第二载波上发送和接收信道占用信令如信道占用请求、信道占用响应等。
基站可能支持第一载波又支持第二载波，上述第一基站和第二基站为同一基站，第一小区和第二小区均由该基站控制。但还存在另一场景，第一小区和第二小区也可以由不同的基站控制，即第一基站和第二基站为不同的基 站，此时第一基站和第二基站会通过一定的方式连接，并在此连接上交互所述第一小区、第二小区和UE的信息，比如本步骤中，第一基站在为UE配置所述第二小区之前，第一基站和第二基站在所述第一基站和第二基站的连接上交互并协商第二小区的配置信息如要为哪些UE配置第二小区，因此在本步骤中，通过以上交互协商过程，第二基站知道第一基站为UE配置了所述第二小区。
步骤320、第二基站通过检测判断第二小区是否可用，如是，执行步骤330，否则，继续检测；
第二基站接收邻近设备在第二载波上发射的信号，比如邻近基站发送的小区参考信号(Cell Reference Signal，CRS)，或者邻近基站发送的服务于小区测量的其他测量信号，还比如邻近WLAN AP发送的信号。
第二基站如接收到邻近设备在第二载波上发射的信号，判断所述信号的信号强度是否高于预设值，如果高于预设值，则判断第二小区不可用，否则判断第二小区可用。
若基站判断所述第二小区不可用，则基站继续检测或者根据预设算法在一段时间T之后继续检测。
步骤330、第二基站在第二载波上发送LTE制式的信道占用请求；
LTE制式的信道占用信令是指信道占用信令的发送采用LTE支持的调制、编码等技术，符合LTE协议标准定义的方式发送。所述信道占用请求中至少包括第二小区的标识信息和信道占用时长。第二基站可以根据期望在第二小区上传输的数据流量、第二小区的负荷、第二小区的信号质量、相关国家法规对可共享使用的载波的占用规定，以及运营商的策略等因素中的一个或多个确定该信道占用时长。
第二基站可以在专门设置的用于发送和接收信道占用信令的公共信道上发送所述信道占用请求。设置可以有不同的方法，比如可以设置每个LTE子帧第二载波的中央N个RB(Resource Block，资源块)为所述公共信道，或者设置每间隔M个LTE子帧第二载波的中央N个RB为所述公共信道；比如还可以设置每个LTE子帧第二载波的中央N个RB中去除最中央6个RB后 的N-6个RB为所述公共信道，或者设置每间隔M个LTE子帧第二载波的中央N个RB中去除最的中央6个RB后的N-6个RB为所述公共信道；比如还可以设置每个LTE子帧的前X个符号上第二载波的全部带宽为公共信道；或者以其他方式设置的公共信道。
可以相互监听到的基站，在设置各自的公共信道时，还可以通过网络配置或相互之间的协商(比如基站之间直接协商或者通过中间协调设备进行协商)，使得相互之间的公共信道在频域资源或者时域资源上相互错开。
第二基站的邻近基站接收到第二基站发送的信道占用请求后，在所述信道占用请求中指示的信道占用时间内，不在所述第二小区使用的第二载波上发起与本基站下的UE的通信。
步骤340、所述UE接收到所述信道占用请求后，检测第二载波上的信号，如确定第二载波可用，在第二载波上发送LTE制式的信道占用响应和WLAN制式的信道占用信令(CTS-to-self)，并激活所述第二小区。
UE内的LTE模块和WLAN模块分别判断第二载波是否可用。
在满足以下条件一和条件二或满足以下条件一和条件三，则LTE模块确定第二载波可用，否则确定第二载波不可用：
条件一，检测到第二小区的信号质量或信号强度超过预设值；例如，通过测量第二小区的CRS，确定第二小区的信号质量或信号强度超过预设值；
条件二，未在第二小区的公共信道上接收到其他UE或基站发送的信道占用信令；
条件三，虽然在第二小区的公共信道上接收到其他UE或基站发送的信道占用信令但所述信道占用信令指示的信道占用时间已过。
如果LTE模块检测到第二小区的信号质量或者信号强度未好于预设值，或者，LTE模块接收到公共信道上来自其他UE或基站的信道占用请求指示要占用第二载波T时间，则在这些UE或基站占用第二载波的T时间内判断第二载波不可用。
LTE模块接收到信道占用请求后，通过UE内部LTE模块与WLAN模块之间的接口，将信道占用请求中的信道占用时长发送给WLAN模块。
WLAN模块执行空闲信道评估，判断第二载波是否空闲，如第二载波空闲，则判断第二载波可用。
当LTE模块判断和WLAN模块均判断第二载波可用时，UE确定第二载波可用，在第二载波上发送LTE制式的信道占用响应和WLAN制式的CTS-to-self。
上述信道占用响应中至少包含UE的标识信息和信道占用时长，该信道占用时长的值可以为信道占用请求中信道占用时长的值减去信道占用请求在空中接口的传输时间、UE接收和处理该信道占用请求的时间，UE发送信道占用响应的信令处理时间及信道占用响应在空中接口的传输时间得到的差值。其中，信道占用请求在空中接口的传输时间和信道占用响应在空中接口的传输时间，可以根据信道占用请求以何种通信制式在空中接口传输，使用该通信制式在空中接口传输时在特定的空中接口信号质量下的平均传输次数等因素确定/约定，不同的通信制式由于技术本身的差异，在空中接口发送一次数据的时间是不同的。UE接收和处理该信道占用请求的时间，由通信标准协议根据一定时期UE内每种芯片和处理器的技术指标规定其接收和处理的最长时间。UE发送信道占用响应的信令处理时间，由通信标准协议综合考虑一定时期UE内每种芯片和处理器的技术指标，发送该信道占用响应使用的通信制式对信令的处理方式等因此规定信令处理的最长时间。
UE在第二载波上发送WLAN制式的信道占用信令，是指该信令的发送采用WLAN支持的调制，编码等技术，符合WLAN协议标准定义的方式发送。该信道占用信令尤其指WLAN 802.11协议中定义的自我信道清空(CTS-to-self)信令，CTS-to-self信令中将接收端地址设置成UE内WLAN模块的地址，CTS-to-self信令还包括信道占用时长，该信道占用时长为WLAN模块从LTE模块处获得的所述信道占用请求中信道占用时长的值减去所述信道占用请求在空中接口的传输时间、UE接收和处理所述信道占用请求的时间(包括内部接口的传送时间)、UE发送CTS-to-self的信令处理时间、UE竞争使用第二载波的退避时间(backoff time)和CTS-to-self在空中接口的传输时间后得到的差值。
LTE模块和WLAN模块都需要在第二载波上发送信道占用响应，为避免 两者之间的干扰，LTE模块和WLAN模块在发送各自的信道占用响应时，可以采用时分复用的方式发送，比如LTE模块发送LTE制式的信道占用响应之后，WLAN模块再发送WLAN制式的信道占用响应，反之也可以。
UE在第二载波上发送完LTE制式的信道占用响应和WLAN CTS-to-self之后，激活UE的所述第二小区，即UE开始在所述第二小区上监听来自第二基站的调度，根据第二基站的调度发送上行数据或接收下行数据，UE还可以在第二小区上发送一些控制信令。
UE邻近的WLAN设备接收到该UE发送的WLAN制式的信道占用信令后，在其指示的信道占用时间内不在所述第二载波上发起数据传输。所述UE邻近的其他基站在接收到该UE发送的LTE制式的信道占用响应后，在所述信道占用响应指示的信道占用时间内不在第二载波上发起与本基站下UE的数据传输。
步骤350、第二基站接收到所述UE发送的LTE制式的信道占用响应后，激活所述UE的第二小区。
激活所述UE的第二小区后，第二基站可以在第二小区上调度所述UE，向所述UE发送下行数据或接收UE发送的上行数据，以及在第二小区上向所述UE发送一些控制信令等。同时，第二基站还可以通知第一基站所述第二小区已被激活。
实施例四
本实施例对应于实施例一和实施例二的方式，同时对UE和基站的处理加以描述。
本实施例提供另一种频率共享方法，适用于多载波场景，UE在使用第一载波的第一小区上与第一基站建立了RRC连接，如图6所示，本实施例的频率共享方法包括：
步骤410、UE接收第一基站发送的第二小区的配置信息并对第二小区进行配置，第二小区使用可共享使用的第二载波；
UE接收并配置了第二小区后，将第二小区置于非激活状态，除了在第二载波上发送或者接收信道占用信令，UE和基站不在第二小区上传输数据。
第二小区的配置信息中，可以包括第一基站期望在第二小区上传输的数据流量，或者第一基站期望UE在第二小区上激活的时间长度。所述UE可以根据所述数据流量估算信道占用时长，或者根据所述激活的时间长度设置信道占用时长。
步骤420、UE检测第二载波上的信号，判断第二载波是否可用，如是，执行步骤430，否则，继续检测；
UE内的LTE模块和WLAN模块分别判断第二载波是否可用。判断方法和实施例三相同，不再赘述。
若UE判断第二小区不可用，则UE继续检测或根据预设算法在一段时间T之后继续检测。
步骤430、UE在第二载波上分别发送LTE制式的信道占用请求和WLAN制式的信道占用请求(CTS-to-self)；
可以设置专门用于发送和接收信道占用信令的公共信道，UE在所述公共信道上发送所述信道占用请求。
UE发送的LTE制式的信道占用请求中，至少包含UE的标识信息和信道占用时长。其中信道占用时长，由UE根据步骤410中接收到的第一基站期望在第二小区上传输的数据流量或第一基站期望UE在第二小区上激活的时间长度确定，确定时可以结合所述UE需要在第二小区上传输的上行数据流量，第二小区的信号质量，相关国家法规对可共享使用的载波的占用规定等因素中的一个或多个。
UE在第二载波上发送WLAN制式的信道占用信令，这里尤其指自我信道清空信令(CTS-to-self)。CTS-to-self信令中将接收端地址设置成UE内WLAN模块的地址，CTS-to-self信令还包括信道占用时长，设置该信道占用时长等于LTE制式的信道占用请求中的信道占用时长。
UE内的LTE模块和WLAN模块都需要在第二载波上发送信道占用请 求，为避免两者之间的干扰，LTE模块和WLAN模块在发送各自的信道占用请求时，可以采用时分复用的方式发送，比如LTE模块发送LTE制式的信道占用请求之后，WLAN模块再发送WLAN制式的信道占用信令，反之也可以。
所述UE邻近的WLAN设备接收到所述UE发送的WLAN制式的信道占用信令后，在所述信道占用信令指示的信道占用时间内不在第二载波上发起数据传输；所述UE邻近的其他LTE基站和其他UE接收到所述UE发送的LTE制式的信道占用请求后，在所述信道占用请求指示的信道占用时间内不在第二载波上发起数据传输。
步骤440、所述UE接收第二基站在第二载波上发送的信道占用响应；
本步骤为可选步骤。
第二基站接收到所述UE发送的LTE制式的信道占用请求后，可以发送一个LTE制式的信道占用响应，该信道占用响应可以在专门的公共信道上发送，信道占用响应中至少包含第二小区的小区标识和信道占用时长，信道占用时长的值等于信道占用请求中信道占用时长的值减去信道占用请求在空中接口的传输时间、第二基站接收并处理该信道占用请求的时间、第二基站发送信道占用响应的信令处理时间和信道占用响应在空中接口的传输时间得到的差值。若第二基站同时接收到多个UE发送的信道占用请求，则在发送的所述信道占用响应中包含第二小区的标识信息，所述多个UE的标识信息及各自的信道占用时长。在第二小区激活进行数据传输时第二基站会对这多个UE采用现在LTE的集中调度方式进行调度，保证它们之间在第二小区上的传输不会产生干扰。
第二基站接收到所述信道占用请求后，激活UE的第二小区；或者在发送信道占用响应后，激活UE的第二小区。激活后，第二基站可以在第二小区上调度UE，向UE发送下行数据或接收UE发送的上行数据，以及在第二小区上向UE发送一些控制信令。
第二基站的邻近基站接收到第二基站发送的信道占用响应后，在所述信道占用响应中指示的信道占用时间内不在第二载波上发起与本基站下的UE通信。
步骤450、所述UE激活第二小区；
若步骤440不执行，则所述UE在第二载波上发送完LTE制式的信道占用请求和WLAN制式的信道占用信令后即激活第二小区；若执行步骤440，则UE在接收到第二基站在第二载波上发送的信道占用响应后激活第二小区。激活第二小区后，所述UE可以开始在第二小区上监听来自第二基站的调度，根据第二基站的调度发送上行数据或接收下行数据，以及UE可以在第二小区上发送一些控制信令。
下面结合网络拓扑，通过应用的示例对上述方案加以说明。
图7所示为一定区域内的网络拓扑，图示区域内，部署了3个LTE的低功率基站节点eNB1，eNB2，eNB3。eNB1，eNB2，eNB3均即支持非共享使用的频率(比如授权独立使用的频率)又支持可共享使用的频率，这里假设：
eNB1支持两个频率F1和F2，其中F1为授权独立使用的频率，F2为可共享使用的频率，eNB1在F1上配置了小区cell1(小区1)，在F2上配置了小区cell2(小区2)，cell1和cell2的覆盖范围相同(实际部署时cell1和cell2的覆盖范围也完全可以不相同)；
eNB2支持两个频率F3和F2，其中F3为授权独立使用的频率，eNB2在F3上配置了小区cell3(小区3)，在F2上配置了小区cell4(小区4)，cell3和cell4的覆盖范围相同(实际部署时cell3和cell4的覆盖范围完全可以不相同)；
eNB3支持两个频率F4和F2，其中F4为授权独立使用的频率，eNB3在F4上配置了小区cell5(小区5)，在F2上配置了小区cell6(小区6)，cell5和cell6的覆盖范围相同(实际部署时cell5和cell6的覆盖范围完全可以不相同)。
3个低功率基站节点中，eNB1和eNB2相互在对方的覆盖区域内，也即eNB1和eNB2可以相互监听到对方。这里，相互监听到对方，以eNB1可以监听到eNB2为例，是指eNB2的射频发射信号可以被eNB1的射频接收装置 接收到，或者指eNB2的射频发射信号可以被eNB1的射频接收装置接收到且eNB1所接收到的信号强度/信号质量好于预设值。
需要说明的是，图1中假设eNB1，eNB2，eNB3均即支持非共享使用的频率(比如授权独立使用的频率)又支持可共享使用的频率，这只是一种可选实施方式而已，事实上，eNB1，eNB2，eNB3还可以仅支持可共享使用的频率，比如仅支持以上可共享使用频率F2，三个基站分别仅配置了F2上的cell2，cell4，cell6，在这种情况下，eNB1，eNB2，eNB3通过一定方式与支持非共享使用的频率(比如授权独立使用的频率)的eNB相连，连接方式比如通过有线的光纤，无线的微波等方式连接。
图5所示区域内还部署了2个WLAN AP(Access Point，AP)，AP1和AP2，均可使用共享频率F2，其中AP1与eNB1相互在对方的覆盖区域内，AP1与eNB2也相互在对方的覆盖区域内，即AP1，eNB1，eNB2可以相互监听到。区域内有很多用户设备，图中只示意了UE1～UE5。eNB1，eNB2，eNB3，AP1，AP2可以由同一个运营商或者不同的运营商部署运营。
eNB1，eNB2和AP1可以互相监听到，当eNB1，eNB2，AP1都在频率F2上传输数据时，相互之间就很有可能相互干扰。eNB1和eNB3虽然不能相互监听到，但是eNB1和eNB3之间有重叠覆盖，以UE1和UE2为例，UE1与eNB1通信，UE2与eNB3通信，两者位于eNB1和eNB3的重叠覆盖区域内且相距较近，当UE1和UE2均使用频率F2分别与eNB1和eNB3通信时，UE1与eNB1的通信链路和UE2与eNB3的通信链路之间很有可能相互干扰。同样，eNB3和AP2之间虽然不能相互监听到，但是eNB3和AP2之间有重叠覆盖，以UE3和UE4为例，UE3与AP2通信，UE4与eNB3通信，两者位于AP2和eNB3的重叠覆盖区域内且相距较近，当UE3和UE4均使用频率F2分别与AP2和eNB3通信时，UE3与AP2的通信链路和UE4与eNB3的通信链路之间很有可能相互干扰。
示例一
以图7所示一定区域内网络拓扑示意图中的基站eNB2和UE5使用共享频率F2为例，图8给出了本示例提出的频率共享方法的信令流程图，包括：
本实施例中，eNB2和UE5在使用共享频率F2之前，UE5在eNB2配置 的cell3上已经与eNB2建立了RRC连接，即cell3为UE5的第一小区，cell3使用的频率F3为UE5的第一载波。UE5在cell3上与eNB2通信，即图8步骤500UE5在cell3上与eNB2建立了RRC连接，UE5在与cell3建立的无线接入链路上与eNB2通信。
步骤510、eNB2为UE5配置第二小区cell4；
eNB2根据业务需要和cell3的负荷，比如UE5当前的业务流量增加，而当前cell3的负荷已经很高，不足以满足UE5新增加的业务需求，eNB2为UE5配置第二小区cell4，cell4使用频率F2，F2为可共享使用的频率。
eNB2为UE5配置了cell4之后，cell4的初始状态为非激活状态，除了eNB2在需要时在F2上向UE5发送信道占用请求，基站不在cell4上调度UE5。UE5接收了cell4的配置信息后，配置cell4，但是不激活cell4，UE5除了有需要时在F2上向eNB2发送信道占用信令，UE5在cell4上不监听来自eNB2的调度。
步骤520、eNB2测量判断cell4是否可用；
eNB2通过测量，判断cell4是否可用。eNB2监听F2上邻近基站或邻近设备发送的信号，本实施例中，eNB2可以监听到来自邻近eNB1和AP1的信号，若eNB2所接收到的F2上邻近基站/设备的信号强度高于预设值，则判断cell4不可用，否则判断cell4可用。
本实施例假设eNB2判断结果为cell4可用。对于cell4不可用的情况，eNB2可以继续检测判断cell4是否可用，或者eNB2可以根据预设算法，在一段时间T之后继续检测判断cell4是否可用。
步骤530、eNB2在cell4所在频率F2上发送信道占用请求。
eNB2在F2上发送LTE制式的信道占用请求，其中，eNB2在专门的用于发送/接收信道占用信令的公共信道上发送信道占用请求，信道占用请求可以以物理层信令方式或者媒体接入层信令方式或者更高协议层次的无线资源管理层信令方式发送。信道占用请求中包含cell4的小区标识和信道占用时长，小区标识比如物理小区标识(Physical Cell Identity，PCI)小区全局标识(Cell Global Identity，CGI)，或者其他类型的能在图7所示的区域内唯一标 识cell4的小区标识。
eNB2邻近的eNB1接收到eNB2发送的信道占用请求后，在信道占用请求中指示的信道占用时间内不在F2上发起与eNB2下UE的通信。
步骤540、UE5接收到eNB2发送的信道占用请求后，在F2上发送LTE制式的信道占用响应和WLAN制式的信道占用信令CTS-to-self，并激活cell4。
UE5内部的LTE模块接收到eNB2发送的信道占用请求后，通知UE内部的WLAN模块，告知WLAN模块F2上信道将被占用的时长。然后UE5在F2上发送LTE制式的信道占用响应和WLAN制式的信道占用信令。其中，LTE制式的信道占用响应在F2上专门的用于发送/接收信道占用信令的公共信道上发送，信道占用响应可以以物理层信令方式或者媒体接入层信令方式或者更高协议层次的无线资源管理层信令方式发送。信道占用响应包含UE5的标识信息和信道占用时长。UE5在F2上先发送LTE制式的信道占用响应，然后再发送CTS-to-self。
UE5发送完上述信道占用信令后，激活cell4，UE5开始在cell4上监听来自eNB2的调度。
需要说明的是，UE5接收到eNB2发送的信道占用请求，在F2上发送LTE制式的信道占用响应和WLAN制式的信道占用信令CTS-to-self前，UE5需要检测F2是否可用(是否空闲)，即UE5需要检测F2是否被其射频接收范围内的其他UE或者WLAN设备或者基站设备使用，其中，UE5可以通过UE5内部的LTE模块和WLAN模块，检测F2是否可用，本实施例中UE5内LTE模块执行对使用频率F2的第二小区cell4的测量，判断cell4的信号质量或信号强度好于预设值，则cell4(F2)可用/空闲，且UE5未在F2上检测到其他UE或者eNB1的信道占用信令或者检测到其他UE或者eNB1的信道占用信令但指示的占用时间已过。此外UE5内部的WLAN模块也检测到AP1未占用F2，因此判断F2可用。本实施例中，eNB2下无法接收到UE5的发射信号的其他UE若也被配置了使用F2的第二小区，这些UE在接收到eNB2发送的信道占用请求后，若判断F2空闲，也可以在F2上发送LTE制式的信道占用响应和WLAN制式的信道占用信令CTS-to-self。
步骤550、eNB2接收到UE5发送的信道占用响应后，eNB2本地激活cell4，即eNB2设置cell4为激活状态，eNB2可以开始在cell4上调度UE5，与UE5通信。
AP1接收到UE5发送的CTS-to-self之后，在CTS-to-self中指示的信道占用时长内，不在F2上发起数据传输。
通过上述方法，步骤530中，eNB2邻近的eNB1接收到eNB2发送的信道占用请求后，在信道占用请求中指示的信道占用时间内不在F2上发起与eNB2下UE的通信，以及步骤550中，AP1接收到UE5发送的CTS-to-self之后，在CTS-to-self中指示的信道占用时长内，不在F2上发起数据传输，可以有效解决eNB2与UE5在可共享频率F2上通信时，避免eNB1，UE5，AP1对eNB2和UE5的干扰，最终实现可共享频率F2在不同设备，不同链路间的共享使用。
示例二
以图7所示一定区域内网络拓扑示意图中的基站eNB3和UE4使用共享频率F2为例，图9中给出了另一种频率共享方法的信令流程图，包括：
本实施例中，eNB3和UE4在使用共享频率F2之前，UE4在eNB3配置的cell5上已经与eNB3建立了RRC连接，即cell5为UE4的第一小区，cell5使用的频率F4为UE4的第一载波。UE4在cell5上与eNB3通信，即图1步骤600UE4在cell5上与eNB3建立了RRC连接，UE4在与cell5建立的无线接入链路上与eNB3通信。
步骤610、eNB3为UE4配置第二小区cell6。eNB3根据业务需要和cell5的负荷，为UE4配置第二小区cell6。
eNB3为UE4配置了cell6之后，cell6的初始状态为非激活状态。
eNB3可以在配置cell6的消息中，发送eNB3期望在cell6上与UE4传输的数据流量。
步骤620、UE4检测cell6是否可用。
本实施例中，UE内的LTE模块执行测量，比如测量cell6的CRS，判断 cell6的信号质量或信号强度好于预设值，且UE6未在F2上检测到其可以监听到的UE3或者的信道占用信令或检测到信道占用信令但其指示占用时间已过，此外UE6内部的WLAN模块也检测到AP2未占用F2，因此判断cell6(F2)可用。如果UE4判断cell6不可用，则UE4继续检测，或者UE4按照预设算法在一段时间T之后继续检测cell6是否可用。
步骤630、UE4在cell6所在频率F2上发送LTE制式的信道占用请求和WLAN制式的信道占用信令CTS-to-self，并激活cell6。
UE4在F2上专门用于发送/接收信道占用信令的公共信道上发送信道占用请求，信道占用请求可以以物理层信令方式或者媒体接入层信令方式或者更高协议层次的无线资源管理层信令方式发送，信道占用请求包含UE4的标识信息和信道占用时长。UE5在F2上先发送LTE制式的信道占用请求，然后再发送CTS-to-self，UE5设置CTS-to-self中的信道占用时长等于LTE制式的信道占用请求中的信道占用时长。
UE4发送完上述信道占用信令后，激活cell6，UE4开始在cell6上监听来自eNB3的调度。
可以接收到UE4信号的AP2和UE3接收到UE4发送的CTS-to-self后，在CTS-to-self中指示的信道占用时间内不在F2上发起数据传输。
步骤640、eNB3接收到UE4发送的信道占用请求后，eNB3本地激活cell6，即eNB3设置cell6为激活状态，eNB3可以开始在cell6上调度UE4，与UE4通信。
通过上述方法，步骤630中，可以接收到UE4信号的AP2和UE3接收到UE4发送的CTS-to-self后，在CTS-to-self中指示的信道占用时间内不在F2上发起数据传输，可以有效解决eNB3与UE4在可共享频率F2上通信时，避免AP2，UE3对eNB3和UE4的干扰，最终实现可共享频率F2在不同设备，不同链路间的共享使用。
